Patent GB-2031595-A (GB)
Title: Leaf shutter for single lens reflex cameras
IPC: G03B9/42
Filed: 1979-07-12
Abstract: The leaf shutter for a single lens reflex camera is so constructed that the closing leaves in their starting position are closed under the side of the film gate away from the viewfinder. During the exposure process, the opening and closing leaves start out towards the viewfinder, and after the exposure, at least the opening leaves return to their starting position automatically. The width of the corresponding closing leaves at any given time in the same plane is smaller than the width of the opening leaves, so that the opening leaves in their starting position covering the film gate overlap each other in the direction of movement by a total which is greater than the total by which the closing leaves overlap each other in their finishing position covering the film gate. In this way, the lower camera space can also be arranged to be smaller.

Patent GB-2036131-A (GB)
Title: Valve Assembly for the Remote Control of Fluid Flow with an Automatic Time Delay
IPC: E21B21/10
Filed: 1979-10-11
Abstract: A downhole float valve 17 is normally closed by a spring 41 until sufficient pressure of drilling fluid from the surface opens the valve. The valve 17 has a stem 33 secured to a piston 37 which moves within a fluid filled cylinder 31. When the valve opens, its movement is controlled by a one-way valve 43 in the piston giving a relatively rapid opening. When pressure of the drilling fluid from the surface is removed, the pressure on the underside of the valve typically assisted by the spring, closes the valve, but an adjustable bleed passage 46 in the piston delays this closing for a pre-determined time to allow the pressure on the underside of the valve to balance with the pressure on the other side of the valve, thus preventing an hydraulic lock situation from occurring. <IMAGE>
