Title: Improvements in pneumatic motors for operating and controlling the doors of vehicles
IPC: E05F15/02
Filed: 1926-01-14
Abstract: 261,572. National Pneumatic Co. Nov. 17, 1925, [Convention date]. Operating and controlling doors pneumatically and electrically; checks. -The cylinder of the motor has connected pistons with two opposing working faces to either of which operating pressure is supplied by control means, additional valve - controlled means being provided for simultaneously supplying retarding pressure to the other of the said faces during the normal closing movement of the door, to build up a predetermined pressure on the exhaust side of the cylinder for regulating the speed of the pistons. In the arrangement shown in Fig. 1, two cylinders 10, 11 are employed, each cylinder having at each end a reducing valve 12 which admits a reduced pressure to that cylinder end whenever operating pressure is admitted to the other cylinder end. The ends of the cylinders are connected through pipes A, B, as shown, the valves 45, 45<1> of which are controlled by small cylinders 44 of the electromagnetic valves 40, 46. A conductor's switch 43 has three positions for completing the circuit of the opening and closing magnets of the valves 40, 46, and for breaking both circuits. In operation, when pressure is supplied through the pipe A to move the piston in the cylinder 10 shown in section in Fig. 2, the air under pressure from the pipe A flows through the pipe 20 to the opening 21, the valve 23 is lifted, and the air passes through the conduits 28, 29 into the chamber 30, to move the piston away from the end of the cylinder. At the same time, pressure is exerted on the cup 31 to move the cup 34 against the face 36 to prevent the pressure in the cylinder exhausting through the pipe 32 and pipe B. When pressure is supplied through Lhe pipe B to the other end of the cylinder, to move the piston in the reverse direction, the pipe A, Fig 2, is open to exhaust and pressure is admitted through the pipe B and conduit 37 to the chamber 33. The cups 31, 34 are then moved by pressure to the left, to permit of pressure fluid passing through the port 32 to the exhaust end of the cylinder. The compressed air thus admitted is sufficient to build up a pressure to check a sudden closing movement of the door. When the pressure in the exhaust end of the cylinder is sufficient to move the cups to seal the member 35 against the face 36, the supply of compressed air is cut off. The arrangement of the operating cylinders and control switches on a car or train of cars may be varied.

Title: A Method of Ascertaining when an Aerial Object is at a Predetermined Distance from a Gun Station.
Inventor: COULSON WILLIAM THOMAS
IPC: G01C3/20
Filed: 1916-02-08
Abstract: 103,693. Coulson, W. T. Feb. 8, 1916. Methods of sighting.-Consists in ascertaining when an aerial object is at a predetermined distance from a gun station, by fixing two telescopes at known distances from, and in the same straight line as the gun, each telescope being supported on two axes at right-angles, one axis in line with the base-line and the other at right-angles to the optical axis. The triangulating scales S, Fig. 1, of the telescopes T are made thus. Referring to Fig. 3, let a semicircle be drawn with B as centre and BP as radius and let two other semicircles, upon which the triangulating scales are to be made, be drawn with the points A and C as centres, so that if a and are the distances of the observing stations from the gun, and gamma is the range at which the gun is to be fired, alpha/AB = #/BC = gamma/PB In other words, A, C, and B show to scale the positions of the observing and gun stations respectively, and PB shows the predetermined range on the same scale. From any point L on the range circle, let lines be drawn to the points A, C cutting the scale circles in the points M, M<1> respectively. Let the points M, M' be given the same number. If this process is repeated for a number of points distributed over the range circle, the scales may be completed so that, in use, when the two scales register the same number, the object is on the surface of the range hemisphere. The height of the object is determined by separate means not described. The image of the scale S may be superimposed upon that of the object by reflection into the field of view of the eyepiece E by means of a plane sheet of glass inside the telescope T, which has an aperture opposite the scale. The illumination of the scale may be adjusted and, in order that a number of concentric scales may be fitted for different ranges, one of the telescopes may be longitudinally adjustable. The sights, fuse, and charge of the gun are adjusted, according to the observed height and predetermined range, before the object reaches the latter, so that the gun may be fired as soon as the two scales give the same reading.
