Diving helmet - Maximus International - www.replicartz.com

Diving helmets are worn mainly by professional divers engaged in surface supplied diving, though many models can be adapted for use with scuba equipment.
The helmet seals the whole of the diver's head from the water, allows the diver to see clearly underwater, provides the diver with breathing gas, protects the diver's head when doing heavy or dangerous work, and usually provides voice communications with the surface (and possibly other divers). If a helmeted diver becomes unconscious but is still breathing, the helmet will remain in place and continue to deliver breathing gas until the diver can berescued. In contrast, the scuba regulator typically used by recreational divers must be held in the mouth, otherwise it can fall out of an unconscious diver's mouth and result in drowning[2] (this does not apply to a full face mask which also continues to serve air if the diver is unconscious).
Before the invention of the demand regulator, all diving helmets used a free-flow design. Gas was delivered at a constant rate, regardless of the diver's breathing, and flowed out through an exhaust valve. Most modern helmets incorporate a demand valve so the helmet only delivers breathing gas when the diver inhales. Free-flow helmets use much larger quantities of gas than demand helmets, which can cause logistical difficulties and is very expensive when special breathing gases (such as heliox) are used. They also produce a constant noise inside the helmet, which can cause communication difficulties. Free-flow helmets are still preferred for hazardous materials diving, because their positive-pressure nature can prevent the ingress of hazardous material in case the integrity of the suit or helmet is compromised. They also remain relatively common in shallow-water air diving, where gas consumption is of little concern, and in nuclear diving because they must be disposed of after some period of use due to irradiation; free-flow helmets are significantly less expensive[citation needed] to purchase and maintain than demand types.
Most modern helmet designs are sealed at the neck using a neoprene "neck dam" which is independent of the suit, allowing the diver his choice of suits depending on the dive conditions. When a neck dam is installed into a drysuit, however, the entire body is isolated from the surrounding liquid, giving an additional degree of warmth and protection. When divers must work in hazardous environments such as sewage or dangerous chemicals, a helmet (usually of the free-flow type or using a series exhaust valve system) is sealed to a special drysuit (commonly made of a fabric with a smooth vulcanised rubber outer surface) to completely isolate and protect the diver. This equipment is the modern equivalent of the historic Mark V "Standard Diving Dress".

We at Maximus International india manufacture replica of diving helmets and many other nautical reproductions.

Brunton compass

Brunton compass, properly known as the Brunton Pocket Transit, is a type of precision compass made by Brunton, Inc. of Riverton,Wyoming. The instrument was patented in 1894 by a Canadian-born Colorado geologist named David W. Brunton. Unlike most modern compasses, the Brunton Pocket Transit utilizes magnetic induction damping rather than fluid to damp needle oscillation. Although Brunton Inc. makes many other types of magnetic compasses, the Brunton Pocket Transit is a specialized instrument used widely by those needing to make accurate degree and angle measurements in the field. These people are primarily geologists, but archaeologists,environmental engineers, and surveyors also make use of the Brunton's capabilities. The United States Army has adopted the Pocket Transit as the M2 Compass for use by crew-served artillery also in nautical.
The Pocket Transit may be adjusted for declination angle according to one's location on the Earth. It is used to get directional degree measurements (azimuth) through use of the Earth's magnetic field. Holding the compass at waist-height, the user looks down into the mirror and lines up the target, needle, and guide line that is on the mirror. Once all three are lined up and the compass is level, the reading for that azimuth can be made. Arguably the most frequent use for the Brunton in the field is the calculation of the strike and dip ofgeological features (faults, contacts, foliation, sedimentary strata, etc.). If next to the feature, the strike is measured by leveling (with thebull's eye level) the compass along the plane being measured. Dip is taken by laying the side of the compass perpendicular to the strike measurement and rotating horizontal level until the bubble is stable and the reading has been made. If properly used and if field conditions allow, additional features of the compass allow users to measure such geological attributes from a distance.

Historical reenactment is a scripted educational or entertainment activity in which participants follow a prearranged plan to recreate aspects of a historical event or period—often a military engagement or display. This may be as narrow as a specific moment from a battle, such as the reenactment of Pickett's Charge presented during the Great Reunion of 1913, or as broad as an entire period, such as Regency reenactment or The 1920s Berlin Project.

Historical reenactment through the ages


Activities related to "reenactment" have a long history. The Romans staged recreations of famous battles within their amphitheaters as a form of public spectacle. In the Middle Agestournaments often reenacted historical themes from Ancient Rome or elsewhere. In the nineteenth century, reenactments were popular in a number of countries, e.g. the Eglinton Tournament of 1839 in Britain. During the early twentieth century they were popular in Russia with re-enactments of the Siege of Sevastopol (1854–1855) (1906), the Battle of Borodino (1812) in St Petersburg and the Taking of Azov (1696) in Voronezh in 1918. In 1920, there was a reenactment of the 1917Storming of the Winter Palace on the third anniversary of the event. This reenactment inspired the scenes in Sergei Eisenstein's filmOctober: Ten Days That Shook the World.
Likewise, mass pageants were used to commemorate civic events like the 150th anniversary of the founding of St Louis, held in 1914.[1] Particularly during and since the centennial of the American Civil War in the United States beginning in 1961, reenactments of Civil War battles has attracted many reenactors, who are some of the most dedicated.
We at maximus international manufacture a huge range of such items.

We at maximus international manufacturers  sextant of different types and techniques and here is a brief introduction of sextant below : 
sextant is an instrument used to measure the angle between any two visible objects. Its primary use is to determine the angle between a celestial object and the horizon which is known as the object's altitude. Using this measurement is known as sighting the object, shooting the object, or taking a sight and it is an essential part of celestial navigation. The angle, andposition line on a nautical or aeronautical chart. Common uses of the sextant include sighting the sun at solar noon and sighting Polaris at night (in the Northern Hemisphere), to find one's latitude. Sighting the height of a landmark can give a measure of distance off and, held horizontally, a sextant can measure angles between objects for a position on a chart.[1] A sextant can also be used to measure the lunar distance between the moon and another celestial object (e.g., star, planet) in order to determine Greenwich time which is important because it can then be used to determine the longitude.
the time when it was measured, can be used to calculate a
The scale of a sextant has a length of  of a turn (60°); hence the sextant's name (sextāns, -antis is the Latin word for "one sixth"). An octant is a similar device with a shorter scale ( turn, or 45°), where as a quintant ( turn, or 72°) and a quadrant (¼ turn, or 90°) have longer scales.
Sir Isaac Newton (1643–1727) invented the principle of the doubly reflecting navigation instrument (a reflecting quadrant—see Octant (instrument)), but never published it. Two men independently developed the octant around 1730: John Hadley (1682–1744), an English mathematician, and Thomas Godfrey (1704–1749), a glazier in PhiladelphiaJohn Bird made the first sextant in 1757. The octant and later the sextant, replaced the Davis quadrantas the main instrument for navigation.
