Luxury caskets often have a double lid, sometimes even a triple lid (the innermost being made of glass). In rare cases, caskets are even double walled (triple walled would be absolutely unusual), which means that the outer casket contains a complete inner casket, which can be taken out. Double walled caskets are much more heavy than double lid caskets, of course.
What else can I help you with?
What is a double walled structure containing the cells genetic code?
The cell membrane is a double-walled structure containing a cell's genetic code.
Why air conditioned buildings have double walled windows?
Because single pane glass is a lousy insulator. The layer of air between the two panes works as an insulator. This improves energy efficiency
What is construction and working of thermos flask?
it consists a double walled glass vessel having a vaccum between the walls.both these walls are silvered on the vaccum side.no heat can enter or leave the inner flask by convection oor conduction across vaccum.a small amount of heat can be gained by the flask through by radiation but the silver surface to control radiant heat and reduce it to a minimum
How much pressure can a full soda can withstand?
Conducted a lab at school measuring the strain on a soda can when it was opened. Back solving for the force as if the can were a thin walled pressure vessel led us to P = -54.447 +- 0.047288 Psi to 95% confidence.
How do you find the operating pressure of a hydraulic cylinder?
this is question related to the strength of materials rather than the hydraulics the basic equation for the stresses in thick walled cylinders will give you the pressure at which the respective hydraulic cylinder can be operated. for radial stress=((piri2 )/ (r02 -ri2)) * ((1 - (ro2/r2))) where pi is the internal pressure of the cylinder ri is the internal radius of the cylinder. r0 is external radius of the cylinder. r is the radius of the point you have selected on the cylinder (this is mostly ri because it is the point were high stress is felt .apparently this formula gives the value of radial stress at point selected by you that is the 'r' value) for tangential stress=((piri2 )/ (r02 -ri2)) * ((1 + (ro2/r2))) adding the 'tangential stress' and the 'radial stress' would give you the value of the 'axial stress' this along with some 'factor of safety' value can determine the operating pressure of the hydraulic cylinder or in this case the internal pressure of the cylinder.
Double rim or triple rim for a bike?
Another muddy question. Rims on a bike can be either single-walled or double-walled, with double-walls being the stronger choice. Never heard of triple walled. Cranks OTOH can have either a single chainwheel, double chainwheels or triple chainwheels. Singles are most common for bikes that are single-speed, have internal gears, or sports bikes built for a specific purpose, like BMX, dirt or track bikes. Double chainwheels are pretty much the standard for road bikes, while MTBs, hybrids and touring bikes often have triples to widen the range of available gears.
What is a double walled structure containing the cells genetic code?
The cell membrane is a double-walled structure containing a cell's genetic code.
What term is a double-walled membrane that encloses the heart?
Pericardium
What is the double walled membrane that contains the blastocyst called?
The double-walled membrane that contains the blastocyst is called the trophoblast. It plays a crucial role in implantation and later develops into the placenta.
What is a double-walled container?
A double-walled container is a type of container that has two layers of walls with space in between. This design provides insulation to keep the contents inside either hot or cold for longer periods of time. Double-walled containers are commonly used for items like insulated water bottles, coffee mugs, and food storage containers.
A nephron begin as double walled globe called?
A nephron begins as a double-walled globe called the renal corpuscle. This structure is made up of the glomerulus and Bowman's capsule, where blood filtration occurs in the kidneys.
What is a double walled with molecules that have hydrophobic tails and hydrophilic head?
Phospholipid Bilayer
What companies manufacture or manufactured copper deposit caskets?
Currently, copper deposit caskets are no longer produced in the US. Copper deposit caskets are caskets which - unlike solid copper caskets which are welded from sheets of wrought copper - are made in a time electrolytic process in which copper molecules are deposited upon a casket form which usually is made of 48 oz copper sheets. While sheet copper caskets weigh between 200 and 300 lbs and are available from $ 2,000 upwards (Online casket retailers' price), copper deposit caskets weigh between 600 and 800 lbs (the typical thickness of the casket walls is 1/8 inch respectively 3mm) and cost up to a dozen times more than standard 32 oz sheet copper caskets. Only cast bronze caskets are more heavy (between 1,000 and 1,200 lbs) and around three times more expensive (currently between $ 160,000 and 270,000). Until the 1980s, copper deposit caskets were manufactured by the Boyertown Burial Casket Company and by the National Casket Company of Massachusetts. The famous National Seamless Copper Deposit caskets had no joints or welding seams nor did the attachments of the handles penetrate the casket walls. The caskets were offered in several designs including a heavily rounded corner design and an urn shaped one. A National Seamless Copper Deposit Casket was used, for example, for the burial of President Franklin D. Roosevelt (a bronze plated round corner model # 21260), for the newspaper magnate William Randolph Hearst (a triple lid round corner design), for Elvis Presley (a round corner model # 21200) for the religious leader Eliajah Muhammad (a silver plated round corner double lid model #21200) and for the burial of singer Aaliyah Haughton (a silver plated model # 20761 with lavish ornamental corners). Boyertown also manufactured several designs. One of their deposit caskets (the model # 2471) was a double walled copper deposited 48 oz bronze unit, featuring an outer copper deposited 48oz bronze casket and another inner solid bronze casket; this luxury model had a hermetically sealed triple lid: the outer one was made of deposited copper and undivided, the middle one had divided panels made from bronze and the innermost lid was an undivided full length oval plate glass panel. The brass bar handles were attached in such a way that they did not penetrate the wall of the outer casket. The casket was available with either a statuary bronze finish or with silver plated exterior. Probably the closest modern equivalent to a copper deposit casket is the "Marquis" model of the York-Matthews Company, a thermo-deposit 48oz bronze casket, weighing around 310 lbs and offered at prices between $ 25,000 and 38,000.
What is the double-walled membrane that produce watery fluids?
The double-walled membrane that produces watery fluids is called the serous membrane. It lines certain cavities in the body and secretes a lubricating fluid to reduce friction between organs.
What material is a thermal flask made of?
A thermal flask is typically made of stainless steel with double-walled insulation to maintain the temperature of the contents. The double-walled design helps to keep drinks hot or cold for extended periods of time by minimizing heat transfer.
Why eskimos make double walled houses of blocks of ice?
Ice is readily available for them, and it is a good insulator.
How does a double-walled glass container cut down on heat loss?
A double-walled glass container creates a layer of insulation between the two walls, reducing heat transfer through conduction and convection. This helps to maintain the temperature of the contents inside the container for a longer period of time compared to a single-walled container.
