Title: Device for controlling the speed of an internal combustion engine
IPC: F02B1/04
Filed: 1972-07-04
Abstract: 1371544 Regulating I C engine fuel supply; stopping ROBERT BOSCH GmbH 4 July 1972 [5 July 1971] 31146/72 Heading F1B and F1K [Also in Division F2] A variable-length link 4, 6, 7, included in the linkage between the accelerator pedal 15 and fuel injection control lever 3 of the engine of a heavy motor-vehicle, more particularly for momentarily increasing and reducing the engine fuel supply during downshift and upshift respectively of a partly automatic transmission, e.g. by electronic control, comprises a cylinder 6 attached to the rod 4, and housing a piston 18 attached to the rod 7, the piston being movable to any of three positions in the cylinder by selective supply of hydraulic pressure to opposite ends of the cylinder under control of two two-position solenoid valves 30, 43, as follows. For the engine "start" position, both valves 30, 43 are energized, position I, so that the right end 21 of the cylinder is exhausted through the valve 43, whilst the left end 20 is pressurized through the valve 30 from a pump 34, thus forcing the piston 18 to the right end of the cylinder and shortening the link 4, 6, 7. For normal regulation by the accelerator pedal, the valve 43 is energized alone, whereby both cylinder ends are exhausted and springs 27, 40 centralize the piston 18 (position shown) and maintain a constant link length.  During downshift both valves 30, 43 are energized and the link is shortened to provide full load as for "start". During upshift the valve 30 is energized alone so that both ends 20, 21 of the cylinder are pressurized and, due to its differential area, the piston 18 is moved to the left end of the cylinder to increase the link length, bringing the fuel lever 3 to a "stop" position for reduced engine speed. When the engine is finally stopped, both valves 30, 43 are de-energized and pressure from a separate accumulator 47 passes through the valve 43 to the right end 21 of the cylinder, establishing the "stop" position, which is maintained by a non-return valve 45.

Title: Improvement in or relating to the manufacture of filters for cigarettes and like smokers' articles
Inventor: LABBE FRANCIS AUGUSTE MAURICE
IPC: A24D3/02
Filed: 1968-06-28
Abstract: 1,224,254. Making cigarette filters. MOLINS MACHINE CO. Ltd. 27 June, 1969 [28 June, 1968], No. 31163/68. Heading A2C. Filters for cigarettes etc. are produced by stationing stubs 5 of paper, cellulose acetate, &c., at spaced intervals on a trough-shaped moving web of wrapper material 1, feeding particulate material from a hopper 12 to the spaces between the stubs, and drawing air through the stubs to assist the passage of the material into the spaces and to cause the wrapper material to conform closely with the stubs. A sprocket-mounted endless band 9 of moulded plastics material has apertures 10 for passage of the particulate material, and portions between the apertures formed as suction ducts 11 to overlie the stubs and arranged to communicate with a stationary suction port 15. The air withdrawn through the port may be filtered to recover any particulate material, in which case such air may be heated to reduce caking in the filters used, and recirculated. Instead of a single port 15 a number of separate ports alternating with pressure ports may be provided whereby the particulate material is agitated and its tendency to cake on the end faces of the stubs reduced. If the stubs comprise a wrapping which is relatively impervious to air they may be punctured by a spiked wheel 8 before they reach the band 9. The stubs may be compressed laterally to increase the height at which the web 1 ceases to be in contact with the stubs. The apparatus may be embodied in a filter making machine as described in Specification 971,491.

Patent GB-1356287-A (GB)
Title: Buffer memory having read and write address comparison for indicating
IPC: G06F5/10
Filed: 1971-07-06
Abstract: 1356287 Buffer memory BURROUGHS CORP 6 July 1971 [6 July 1970] 31757/71 Heading G4C A buffer memory comprises a memory 12 adapted for connection between transmitting and receiving means and to supply data to the receiver when requested by the latter, a means responsive to the writing of data into and the reading of data from the memory to supply to the receiver an attention needed signal indicating that the memory stores data which has not yet been demanded by the receiver, and means for storing an overflow indication in the memory when the latter is full and a further input occurs. As described the memory 12 contains four word locations and is coupled to the transmitter and receiver via input 11 and output 13 AND gates. Initially the write and read address registers 16, 15 indicate the same location in the memory. When the transmitter wishes to transmit data it supplies a "ready" signal to the occupancy determining circuit 18 which, if a memory location is available, enables the input AND gates so as to transfer the data into the memory and subsequently increments the write address register to indicate the second location in the memory. The occupancy circuit responds to the difference in the addresses indicated by the write and read address registers and supplies a low priority "attention needed" signal ANPI to the receiver. If the receiver accepts the data before the transmitter sends further data the output gates 13 are enabled and the read address register 15 subsequently incremented. The read and write address registers thus indicate the same address and no attention needed signal is generated. However if further data is sent by the transmitter the input sequence repeats with the additional signal NWO being generated to indicate to the receiver that a further word has been transmitted. Following the third such transmission without any action being taken by the receiver a higher priority attention needed signal ANP2 is generated. Following a fourth such transmission the buffer becomes full and the write address register is not incremented to prevent overwriting. Following a fifth request for transmission the input AND gates are not enabled and a signal OWS is passed to gate 11-9 to write a bit into the last word in the buffer which indicates to the receiver, when that word is accepted, that an overflow has occurred. The Specification describes a number of simple gating circuits some of which include flip-flops for generating the signals produced by the occupancy circuit. The system may be used as an interface between an input (e.g. a process) and a digital computer or between a digital computer and an output (e.g. a printer). It is mentioned that an up/down counter may be used to indicate the occupancy or otherwise of the buffer store. The memory 12 may be a semi-conductor integrated circuit device.
