Title: Photographic camera
IPC: G03B9/70
Filed: 1969-12-01
Abstract: 1286648 Preventing double exposures AGFAGEVAERT A G 1 Dec 1969 [30 Nov 1968] 58516/69 Addition to 1135150 Heading G2A A camera having a double exposure preventing means has a slide 5 acting under a spring 7 which is released by the camera release to actuate the shutter, the slide then being returned to its initial position by the film advance, during which return movement it rotates a multiple flash device into position for the next exposure. As shown, the slide 5 can slide and pivot on a fixed pin 6. It is tensioned, in the position shown, by spring 7, and held in that position by the camera release 8 which latches into a lug 5b on slide 5. A further lug 5c holds a spring-loaded lever 10 against clockwise rotation about a pin 9. A feeler and locking lever 17 is mounted on a pin 18, and has a feeler arm 17a which can enter into a perforation 2a in the film sheet 2 (as shown in the Figure) and a locking arm 17b which is shown as engaging in a ratchet wheel 15 on the film transport, so blocking any further movement. When shutter release 8 is pressed, slide 5 is freed to act under the tensioned spring 7 and spring-loaded lever 10, which imparts both a translatory and a rotary movement to the slide (as shown by arrows 19 and 20). It is briefly brought high enough to strike member 4, which actuates the shutter. As lever 10 moves clockwise under spring 11, it lifts lever 17, so that arm 17a is lifted out of the perforation 2a, and arm 17b is also disengaged from ratchet wheel 15. Thus further film transport is now possible. During this transport movement, one arm of a cam 13 on the film transport engages on arm 5e at the end of slide 5, and pushes it back again (to the left, as shown). Lever 10 is therefore pivoted anticlockwise again, and arm 17a rests against the film until the perforation corresponding to the next film frame aligns with it. The arm then enters the perforation, and arm 17b again locks the ratchet wheel. During this return movement of slide 5, a further lug 5d engages a cam arm 12a of a flash-cube socket 12, and rotates it, and hence an associated flash-cube, to its next position.

Title: Fluid control circuit
IPC: F15B13/04
Filed: 1972-12-20
Abstract: 1414639 Dozers CATERPILLAR TRACTOR CO 20 Dec 1972 [23 Dec 1971] 58859/ 72 Heading E1F [Also in Divisions Fl and F2] A control circuit, e.g. for the blade lifting ram 13 of a bulldozer, includes a reversing valve 24 with a spool 28 which in the neutral position disconnects service chambers 46, 47 from exhaust chambers 51, 52 and supply chamber 23, the pressure in the latter then being held at a low level by bypass spool 64 which connects the chamber 23 to exhaust at 69. Upon movement of the spool from the neutral position, the pressure in the service chamber then connected to the supply chamber is admitted by selector, ball 83 and spool 87 to chamber 68 above spool 64 so that the supply pressure rises -to match the load, and while a service chamber is receiving fluid, solely via the metering slots 63 in spool 28 a constant pressure differential, as determined by spring 32, is maintained between that service chamber and the supply Chamber, but once the spool 28 has been moved far enough to -establish unrestricted communication between that service chamber and the supply chamber the pressure differential disappears, the pilot relief valve 94 being operable at that stage to prevent excess pressures in the circuit. The circuit may include a second reversing valve 34 controlling, e.g. the blade tilt ram 21, and in such case pilot pressure applied to valve 34 may be simultaneously applied via selector 98 to cause spool 97 to interconnect opposite sides of spool 64 which then again functions simply as a pilot-operated release valve. In modifications: (a) the metering slots in spool 28 are omitted and an auxiliary metering spool is provided which is linked to spool 28 (Fig. 2, not shown); (b) the metering slots in spool 28 are omitted and that spool is linked to spring 32 to cause progressive relaxation thereof as spool 28 is moved from neutral (Fig. 3, not shown); (c) the metering slots in spool 28 are again omitted and the auxiliary metering spool of (a) is included together with the linking of the spool 28 to the spring 32 as in (b) (Fig. 4, not shown); and, (d) the spool 87 and selector 83 are omitted and chamber 68 is connected, instead to the service chambers via further slots in the spool 28, these slots serving to exhaust the chamber 68 when spool 28 is in its neutral position.

Title: A data processing system incorporating a bus
IPC: G06F13/42
Filed: 1978-10-25
Abstract: A digital data processing system includes an interconnection connected to the various elements each called a nexus, that constitute the system. For one element 32A to communicate with another element 32B, the one element, as a commanding nexus, seeks control of the interconnection and then transmits a command and address of a storage location in the other element when it receives control of the interconnection; the other element sends to the one element a confirmation signal in response to receipt of the command and address. Control is then relinquished unless the one element is to send data to the other element whereupon the data is sent immediately. If data is to be retrieved, the other element retrieves the data, requests control of the interconnection and, when it receives control transmits the data onto the interconnection with an identification of the one element which was included in the command transmitted by the one element and has been temporarily stored in the second element. The one element then retrieves the data from the interconnection when it recognizes its own identification. If the other element is a memory element, it also contains a storage file for storing commands and data if it already is operating in response to another element command. <IMAGE>
