Apparatus for delivering and recording measured quantities of liquid comprises a piston 12 reciprocable in a cylinder 1 having a port at each end communicating with ports in a valve chamber 6 connected by other ports 2, 8 to a delivery conduit and a supply of liquid, respectively, the piston, the movement of which is transmitted to a recording apparatus, acting through a lost-motion connection at the end of its stroke to connect one end of the cylinder to the supply of liquid and the other end of the cylinder to the delivery conduit. The rod 9 of the piston is secured to members 19, 20 which slidably receive a rod 15 carrying adjustably mounted collars 16, 17 and a pin 18. At the end of the strokes of the piston, adjustable cam members 28 carried by the members 19, 20 alternately engage detents 24, 25 which are thus alternately disengaged from the collars to permit springs 21 or 22 to axially move the rod 15. The rapid movement of the rod causes the pin 18, which engages a cam 26, to rock a spindle 27 carrying a plate 3 to alternately connect one or other of the ports communicating with the ends of the cylinder to the delivering port 2 by means of a recess in its upper surface, the supply conduit leading to the chamber 6 then being connected to the other uncovered port leading to the other end of the cylinder. The movement of the piston is transmitted by a rack-andpinion mechanism 32, 33 through two trains of gears provided with one-way clutches to a pointer 30, a second rack being adjustably mounted on the first to vary the backlash between the rack and pinion.

Title: Rotary disc shutter for photographic cameras
IPC: G03B9/08
Filed: 1955-09-12
Abstract: 779,430. Photographic shutters. ZEISS-STIFTUNG C., [trading as ZEISS, C. [Firm of]]. Sept. 12, 1955 [Sept. 13, 1954], No. 25956/55. Class 98(1) A photographic shutter is provided with a number of pairs of discs, e.g. four discs having cutout portions and rotating at constant speed in two planes, two in each plane, the cut-out portions alternately covering and uncovering the lens, and with a pivoted apertured blade movable to uncover the lens aperture to effect the exposure, and optionally with an additional rotatable disc having a cut-out portion selecting the successive exposure positions of the four discs. As shown in Fig. 2, the shutter comprises four rotatable discs 1, 2, 3 and 4 with the discs 1 and 2 in one plane and the discs 3 and 4 in another plane. A further disc 5 rotates at a lower speed than the discs 1 to 4, all the discs 1 to 5 having cut-out portions. A blade 6 having an aperture 7 alignable with the optical axis is pivoted at 8. As shown in Fig. 3, a release impulse produced periodically by an intervalometer energizes the electromagnet 10 to attract the lever 12 to free the latch 15 from the spring-urged lever 19 to permit its extension 21 to move towards the co-axial levers 23, 24. The continuously rotating cam 26 rotating synchronously with the disc 5 is so arranged that when the cam follower roller 32 is nearest the axis of rotation of the cam 26, the cut-out portions of the discs 1 to 4 are in alignment. If the levers 23, 24 are separated as shown when the extension 21 moves, the extension enters the space between them and locks them together, whereupon the cam 26 rocks the lever 24 through its camfollower disc 25 and thus moves the extension 29 of the lever 23 away from spring- urged lever 30 to permit this lever to swing clockwise to rotate the shaft 8 of the blade 6 through the rod 34 and link 35 to align its aperture with the optical axis. At the same time, the pin 36 restores the lever 19 to its initial position.

Title: Variable speed and torque transmitting fluid clutches
Inventor: THOMAS JOHN ROBERT
IPC: F16D31/04
Filed: 1959-07-30
Abstract: 877,950. Hydraulic clutches. THOMAS HYDRAULIC SPEED CONTROLS Inc. July 30, 1959, No. 26239/59. Class 69 (2). An hydraulic clutch comprises a casing which is rotatable with a driving shaft and has a chamber partially filled with oil so that during rotation an outer annular zone of oil is formed around an inner zone of air, and fluid circulating power transmitting means having air suction 501, 502, 503, Fig. 1, oil suction 36a, 36 and fluid discharge 400, 401, 504, 305, Fig. 6, circuits, the air suction and fluid discharge circuits being controlled by a single valve 500 and the oil suction circuit being constantly open, the valve means being adjustable to provide air and/or oil to the power transmitting means to vary the speed and/or torque transmitted by the clutch. The clutch is of the type described in Specifications 709,122 and 770,569, with the valve and supply passages to the gear pumps modified. In the present embodiment, the valve 500, Fig. 1, is axiallymovable by rods 53 and a collar 58 and is formed as a flanged cylindrical member with the air suction passage consisting of a channel 501 in one face of the flange communicating with passages 502, 503 which open on to the cylindrical surface of the valve, the openings of the passages having the shape shown in Fig. 13. The passages co-operate with openings 601, 602 in a manifold 42 communicating with the inlet cavities 36b, Fig. 14, of the gear pumps. The cylindrical portion of the valve 500 is also formed with ports 305, Fig. 6, having slotted openings 504 co-operating with recesses 400 in the manifold which are, in turn, connected to the exhaust cavities 34b of the gear pumps, the ports 401 and slots 504 having the shape shown in Fig. 13. The inlet cavities 36b are also connected by the oil suction passages 36 to ports 36a which are constantly open to the outer annular zone of oil. In the neutral position of the clutch, the valve 500 is in its axially innermost position, the passages 502, 503 and openings 601, 602 and the slots 504 and ports 401 being in register, the gear pumps drawing air only from the inner zone and passing it to exhaust. Axial movement of the valve first moves the passages 503 and openings 602 out of register and some oil is drawn in by the pumps to transmit low torque. Further movement of the valve moves the passages 502, 601 out of register so that the air suction passage is closed; the slot 504 has, in this position, moved from the wider to the narrower part of the port 401 to reduce the flow through the discharge passage to assist in transmitting increased speed and/or torque. In the axiallyoutermost position of the valve, the passages 502, 503 and openings 601, 602 and the slots 504 and ports 401 are out of register so that the clutch transmits maximum speed and/or torque.

Title: Improvements relating to fuel and air regulating means for mixture-compressing injection internal-combustion engines
IPC: F02D9/00
Filed: 1956-08-28
Abstract: 800,258. Regulating. DAIMLER-BENZ A. G. Aug. 28, 1956 [Aug. 30, 1955], No. 26300/56. Class 7(6) A thermostat 25 controlled by the temperature of the engine cooling water, cooling air, or lubricant, is connected through a mechanical connection to the fuel injection pump control means 7 and also controls a throttle member 27 in the idling air passage 4. The control rod 7 is controlled by a suction governor 10 connected to a lever 31 pivoted at 30 and actuating the rod 7 through a lever 13 pivoted thereon at 32 and connected to the thermostat 25 through a slidable capsule 12 resiliently connected to a lever 17 in contact with the end of valve 27. The capsule 12 is responsive to atmospheric pressure and temperature and is urged towards the right by a spring, its movement towards the left being limited by a flanged head 15 which is in contact with a spring-loaded abutment 18 carried by lever 17. The valve 27 also controls a passage 28 which adjusts the suction applied to governor 10. When the engine is cold thermostat 25 moves valve 27 to the left to open passage 4 for fast idling and move lever 17 clockwise, allowing the capsule 12 to be moved to the right whereby lever 13, for any position of lever 31, adjusts rod 7 towards the increased fuel supply direction. As the temperature of the cooling water, supplied at 22, increases, valve 27 is moved to the right to throttle passage 4 and rotate lever 17 anticlockwise, whereby the enriching correction applied by lever 13 is reduced, and the passage 28 is gradually opened to reduce the suction applied to the governor diaphragm 10 through pipe 5 and effect a subsidiary correction to the fuel supply, which correction varies with load. The resilient abutment 18 permits rotation of the lever 17 beyond the position in which the flange 15 attached to capsule 12 has reached its limit of travel in order to allow valve 27 to move to the position, in which it completely blocks the idling air passage 4 at normal running temperatures. Reference has been directed by the Comptroller to Specification 768,323.
