During “Deadly relics Second part. Hermione pulled out a long, thin glass bottle that caught Harry Potter’s tears. The tradition of the “tear catcher” is the dream of many merchandisers. Tears from Potter fans are undoubtedly a joy for antique dealers.
The history of tear catchers, also known as tear gas canisters, goes back centuries. In the Bible they are mentioned. Egyptian and Roman examples are provided. Because these bottles were associated with wealth, it is likely that those with extra denarii could store tears in them.
In Victorian times, tear catchers were used by all classes as soon as they were reintroduced. A special bottle was used to collect tears upon the death of a loved one. Tears could evaporate through tiny holes in bottle caps. The mourning period ended when a dry bottle was found.
Before going on duty, soldiers gave their wives watery bottles. Over time, their wives added more tears to the glass cylinders after they left. The bottle is full when he returns home after an extended absence, and he knows his wife has been crying while he was gone. Soldiers’ wives shed their tears on their husbands’ graves to mark the end of a year of mourning.
Many women shed tears at the end of Aspen’s mining era. These people died young because life was hard for them. During childbirth, many women died and many children died before reaching adulthood. The widows faced many financial challenges after the death of their hardworking husbands.
There were four undertakers needed as the Aspenites were dying at a high rate. E. Turley was busiest during the summer at E. Turley of Cooper Avenue. Wilson and Allen fought at South Mill in the 1890s. During his term as coroner, Johnsen worked for a long time. His business was purchased between the Jerome Hotel and Main and Mill by Belden and Beall.
Collins Block Building, located in a prominent area, was occupied by Belden and Beall. The furniture business they ran was similar to that of all the funeral directors and embalmers in Aspen. Funeral coffins were made by furniture makers on the occasion of funerals.
Funeral homes today sell funeral accessories much like car dealerships do for their vehicles. Jewelers and perfume makers instead took advantage of the Victorian undertakers in fashion at this time.
Have you ever marveled at the movement of a dolphin, the movement of a seal or the movement of a shark? It seems that moving them is not difficult. Over millions of years they have evolved to become fast and agile as marine predators. Since water has a density 800 times greater than air, increasing speed requires great propulsion power. Streamlining helps reduce drag while moving efficiently through the water.
2nd Reason for TRIM
Diving in balance means facing the surface. In order to move efficiently through the water, it is essential to have a good horizontal trim. In your drysuit, weight placement, BC weight, and throttle positioning all contribute to a successful fit. Good vertical trim can be achieved by competent backmount divers as well as good horizontal trim. Your cylinders are positioned on either side of your body, allowing them to be more closely aligned with your center of gravity and buoyancy.
Finally, there is a balance
Both sides of your torso will have side mounted cylinders. Whatever your position, your center of gravity and buoyancy will always be close to the center. Your balance is never affected by your position, whether you are upright or inverted.
Sidemount diving appeals to me for the following reasons.
FIRST, STREAMLINING IS IMPORTANT
Dolphins, seals and sharks move with such grace, how many times have you been amazed by their movements? They seem to move effortlessly. As marine predators, they have evolved in speed and maneuverability over millions of years. Due to the density of water being 800 times that of air, increasing speed requires significantly more propulsion power than increasing speed. When moving efficiently through the water, streamlining is important to reduce drag.
The second reason is to prune
A diver is generally considered in equilibrium if he is facing the surface. The horizontal trim is essential to move efficiently through the water. It is important to place your weight, weigh your BCD and position your gas correctly in your drysuit to get an effective trim. Sidemount divers should have good horizontal trim, although backmount divers can achieve good vertical trim as well. Because your cylinders are at the sides of your body, they align closer to your centers of gravity and buoyancy, resulting in a pro-trim effect.
The third reason is balance
The side mounted cylinders will be on either side of your torso. Your centers of gravity and buoyancy will always be close to the center of your body, regardless of your position. It doesn’t matter whether you are upright or upside down, you are balanced.
On the other hand, backmounting consists of hanging your bottles on your back.
If you turn to the side, you will create a moment or a strong force that pulls you back. Although controllable with body tension, it can be disconcerting and interfere with a sense of balance when diving.
Decompression stop of a sidemount diver
The fourth reason is STABILITY
Stability depends on adjustment, balance and buoyancy. Staying poised and poised is the essence of stability. When your buoyancy balances your gravity, you are in balance. In addition to being weightless, you are now a stable platform from which to perform tasks or skills. Silt caused by contact with cave or shipwreck floors can reduce visibility in overhead environments, such as caves or shipwrecks. Performing gas changes while maintaining specific depths is another requirement of decompression diving.
5th reason for dismissal
Redundancy is another important reason to dive with two or more cylinders in addition to being able to carry more gas. It provides additional safety in the event of equipment failure or diver error. In multiple cylinder configurations, cylinders and regulators are redundant. Side-mounting the gas supplies provides two independent gas supplies, as opposed to one isolation valve. It is a distinguishing feature that has advantages and disadvantages.
