Title: Address manipulation circuitry for a digital computer
IPC: G06F12/08
Filed: 1970-11-04
Abstract: 1328268 Digital computers; address modification BURROUGHS CORP 4 Nov 1970 [16 Feb 1970] 52379/70 Addition to 1188436 Headings G4A, G4A A digital computer is a modification of Specification 1,188,436. It comprises a computer memory, a peripheral memory e.g. disc or magnetic tape, and address manipulation circuitry including a source of copy descriptors and original descriptors referencing information stored in groups of memory cells forming arrays in the computer memory. Provision is made for making space in the computer memory by transferring data to the peripheral or backup memory and subsequently transferring it back again when it is needed (this process is referred to as overlay) and the Specification is concerned with the addressing during overlay. Descriptors.-Memory cells or arrays of cells are referenced using copy or original descriptors, a descriptor being defined as a digital word including addresses of items of data or program information stored in the computer memory. The first time a cell 3 is referenced an original descriptor 12 is used (Fig. 3) including a field 13 designating a base address value, a field 14 designating length, a field 15 designating the nature of the field 13 (e.g. base address in computer memory) and a field 16 designating the type of descriptor. On subsequent referencing of a cell, a copy descriptor is used comprising a field 8 designating the base address value, a field 9 designating an index value of the cell relative to the base address, a field 10 designating the nature of the field 8 and a field 11 designating the type of descriptor. This Specification is concerned with a modification whereby a copy of a descriptor is generated which descriptor may be an original or a copy descriptor. If the descriptor is an original descriptor referencing information absent from the computer memory, a copy is generated having a first field designating the memory location of the original descriptor, a second field designating an index, a third field designating that the first field is an original descriptor location and a fourth field designating that the descriptor is a copy. If the descriptor is an original descriptor referencing information in the computer memory a copy is generated identical to the original descriptor except for the fourth field which designates a copy descriptor. If a copy descriptor is found, an identical copy is made.

Filed: 1964-11-30
Abstract: 1,095,708. Flowmeters. J. L. HARTSTONE. Dec. 31, 1964, No. 52925/64. Heading G1R. A metering and flow indicating device for use during milking operations comprises a cylindrical chamber 1 which may be connected to a milk supply 3a, an outlet 9 leading from the chamber, milk distributing means within the chamber and capable of passing milk from the supply in an evenly distributed flow on to the interior wall 5 of the chamber, and a metering cup 12 set about the entrance to a discharge tube 10, the area of the metering cup being of a selected ratio relative to the cross-sectional area of the interior of the cylindrical chamber, so as to pass a selected proportion of milk through the metering cup to a graduated scale 11a to indicate the weight of the milk taken from the cow. In the embodiment shown in Fig. 1 the milk distributing means comprises a conical like protuberance 4 formed on the concave undersurface 5 of the closure 2 and positioned directly over the top of the inlet pipe 3. The deflection of the milk is also assisted by a circular collar 6 on the inlet pipe 3 which provides an annular space 6a. The discharge pipe 10 extends upwardly through the chamber 1 to a short distance below the top 1a of the chamber. The metering cup 12 is positioned within the annular space 6a and fitted on the upper open end of the discharge tube 10. The lower end of the discharge tube 10 is connected by a length of transparent piping 10a to a graduated measuring glass 11.

Title: Fuel injection pumping apparatus
IPC: F02M41/14
Filed: 1974-12-06
Abstract: 1533385 Fuel injection pumps; extra fuel for starting CAV Ltd 25 Nov 1975 [6 Dec 1974 1 April 1975] 52969/74 and 13304/75 Headings F1A and F1B In a rotary distributer fuel injection pump comprising a multi-lobed cam ring 17 for imparting, via rollers 19 and shoes 18, inward movement to pumping plungers 15 reciprocable in a bore 14 in a rotary member 12, the maximum permitted outward strokes of the plungers are controlled by axially spaced stop rings 32, 33 for the ends of the rollers, the axial spacing being temporarily increased when the pump is required to deliver excess fuel for starting the engine supplied by the pump. During normal operation the actual outward strokes of the plungers is determined, within the maximum permitted by the stops 32, 33, by the position of a throttle 21 in the inlet flow-path to the bore 14. The throttle is controlled conventionally by a centrifugal governor including a spring 28a adjustably tensioned by an operator controlled shaft 29. The excess fuel position occurs when angular adjustment of a ring 37 mounting the stop ring 32 allows axial projections on the ring 37 to enter complementary recesses in a fixed ring 38, Figs. 6 and 7 (not shown). The ring 37 is angularly movable by a peg 39 depending from a plate 41, 45, 43 pivotable about a pin 42. An operator actuated cam 51 is provided for engaging an extension 50 on the plate 41 and moving the latter to its excess fuel position against the action of a leaf spring 44. Once the plate 41 has been moved to its excess starting position, a headed pin (46), Fig. 3 (not shown), is depressed by a leaf-spring 48 until the head 47 thereof obstructs movement of the plate back to its normal position. At this time the end of the pin (46) opposite the head 47 is received in recess (49) in the cam ring 17. After start-up the cam ring 17 is turned by a mechanism (not shown) to advance the timing and this lifts the pin (46) so that the spring 44 pivots the plate 41 back to its normal position abutting the shank of the pin (46). Operation of the cam 51 can also displace, via a pin 53, a shut-off plate 54 to pivot a lever 28 to a position which closes the throttle 21. In a second embodiment, Figs. 8-12 (not shown), the stop ring 133 is angularly movable to its excess fuel position by an actuation piston (137) urged by a spring (139). Movement of the piston (137) is only possible when an externally controlled member 140 is turned to a predetermined position, Fig. 12 (not shown). After startup a valve (142) acts to delay the supply of fuel for moving the actuation piston (137) to its normal position. The actuation piston is arranged to control ports in a circuit arranged to effect a retardation in the timing during the delivery of excess fuel.

Title: Temperature stable integrated oscillator
IPC: H04Q1/453
Filed: 1971-11-24
Abstract: 1342808 Oscillator SIGNETICS CORP 24 Nov 1971 [7 Dec 1970] 54592/71 Heading H3T A temperature stable integrated circuit oscillator comprises a bi-stable circuit whose output voltage swing is a function of V - 2Vbe, where V is the supply potential and Vbe is the forward voltage drop of the base emitter junction of each of two transistors in the bistable, which output voltage is applied to an RC tuning circuit, the voltage swing across the capacitor of which is compared to a respective one of two reference voltages, the difference of which also follows said function of V - 2Vbe, and when equal causes the bi-stable to be appropriately set or reset to initiate the next half cycle of oscillation. As shown, transistors Q 1 -Q 6  and Q 9 , Q 10 , Q 12  and Q 13  are the bistable whose output W 1  swings between V<SP>+</SP>- Vbe and Vbe and is applied to an external timing network R 1 C 1 , the output W 2  of which is applied via emitter follower Q 8  to the comparators 32, 33 having reference potential inputs V 1 , V 2  respectively and which respectively operate SET (W 3 ) or RESET (W 4 ) inputs to the bistable when the output W 4  equals V 1  or V 2 . The reference potentials V 1 , V 2  are a function of V - 2Vbe due to transistors Q 20 , Q 21  whose baseemitter paths thermally track with those of the bi-stable. The oscillator frequency depends on the current through the string 34 of resistors and transistors Q 20 , Q 29 . When used in a phase lock loop (Fig. 1, not shown) to detect an input-signal within a particular frequency range; a phase detector 13 receives the input signal together with the oscillator output W 1  and drives an amplifier 16 to control current I D  and obtain "lock". A quadrature phase detector 22 receives the amplified output W 5  of the bi-stable and a push pull output of the input signal from phase detector 13 to detect "lock". By varying the time constant of a low pass filter (14, Fig. 1, not shown) using capacitor C 2  the capture range of the phase locked loop can be controlled. The current control to alter the frequency of the oscillator also follows the same function of V<SP>+</SP> -2Vbe by mixture of bias supply 41.

[Also in Division D1] Apparatus for treating (e.g. drying or steaming) a layer of material (e.g. web, sheet or granular layer) comprises a conveyer for the material and a blow box comprising a pair of adjacent ducts, each duct having a nozzle, the nozzles extending transversely to the path of travel of the material and being inclined towards each other such that the gas streams flowing therefrom converge and merge to form a common stream at least at the path of travel of the material. The ducts of said pair having gaseous inlet means at opposite ends with respect to one another so that a swirling motion is created upon convergence of the streams. In one embodiment (Fig. 2) a web W is carried on a tenter chain conveyer 12 through an apparatus comprising air inlet and outlet locks (not shown), and a plurality of blow boxes 30a, 30b positioned above and blow the path of the web. Each blow box comprises ducts 32, 33 having inlets 34, 35 respectively and carrying inclined nozzles. The ducts taper from their inlet ends. The ducts are positioned in a suction chamber 27 and receive gas from blower 20 via a filter 24, a heater 25 and a plenum chamber 23. The ducts may be spaced from each other such that the issuing gas streams create a Venturi effect causing air to flow from the space between the ducts (Fig. 4). This space may be closed off by an adaptor (50, Fig. 7, not shown). In Fig. 10 ducts 231, 232 receive gas from the same plenum chamber 213, the gas by-passing the inlet 233 of duct 231 being directed by arcuate deflector 237 into duct 232. The ducts and nozzles may be formed by a partition 333a (Fig. 17) (not shown), the position of the partition in the blow box being variable to vary the nozzle openings.
