4,4′-Methylenebis(2-chloroaniline) (also known as MOCA, MBOCA, and bisamine) is a substance used as a curing agent in polyurethane production. [3] MOCA is an aromatic amine which is structurally similar to benzidine , a known human bladder carcinogen.
The sheet has a solid end and a flow-through end; sliding it from one position to the other opens or stops the flow. Also called sliding blind valve; Outflow valve: regulates flow and pressure, part of cabin pressurization; Pilot valve: regulates flow or pressure to other valves; Petcock, a small shut-off valve
The MoCA is a one-page 30-point test administered in approximately 10 minutes. [2] The test and administration instructions are available for clinicians online. The test is available in 46 languages and dialects (as of 2017). In this clock drawing task, the subject is asked to draw a clock with the hours and showing the time 2:30.
With proper analysis, problems relating to valve adjustment, hydraulic tappets, push rods, rocker arms, and above all, valve float, became things of the past without desmodromic drive. Today [ when? ] most automotive engines use overhead cams , driving a flat tappet to achieve the shortest, lightest weight, and most inelastic path from cam to ...
The balls swing out as speed increases, which closes the valve, until a balance is achieved between demand and the proportional gain of the linkage and valve. A centrifugal governor is a specific type of governor with a feedback system that controls the speed of an engine by regulating the flow of fuel or working fluid , so as to maintain a ...
PFD avg = [(1-PTC)×λ D ×(TI FC /2)] + [PTC×λ D ×(TI PST /2)] Where: PTC = Proof test coverage of the partial stroke test. λ D = The dangerous failure rate of the safety function. TI FC = The full closure interval, i.e. how often the valve must be full closed for testing. TI PST = The partial stroke test interval.

A Tesla valve, called a valvular conduit by its inventor, is a fixed-geometry passive check valve. It allows a fluid to flow preferentially in one direction, without moving parts. The device is named after Nikola Tesla , who was awarded U.S. patent 1,329,559 in 1920 for its invention.
