Title: Arrangement for testing a peripheral associated with a data processing
IPC: G06F11/267
Filed: 1975-10-15
Abstract: 1516538 Testing data processing peripheral units COMPAGNIE INTERNATIONALE POUR L'INFORMATION CII-HONEYWELL BULL 15 Oct 1975 [28 Oct 1974] 42333/75 Heading G1U [Also in Division G4]  Faulty peripheral equipment of a data processing unit is tested under the control of a stored programme which provides excitation signals to the circuits in the peripheral equipment, digital and analogue signals at test points therein being converted to logic levels and fed via multi-plexing to an analyzing arrangement which identifies the fault. The peripheral P1 e.g. a disc store has circuitry TEST controlling its various functions e.g. analogue circuitry for disc rotation control, digital circuitry for read/write head control, position sensing and write/scan control, Fig. 7 (not shown). These circuits have associated test points e.g. PA 1  PA 2  (analogue) and PL 1  - PL 8  (digital). The data processor central unit P2 has stored therein a test programme operative when the peripheral malfunctions Figs. 6a, 6b (not shown). Programme signals are sent to a control circuit COM Fig. 4 (not shown) which in response triggers setting circuit INIT to reset stores M1, M2 to zero, and signal back to control COM. Multi-plexers MULT are then set to relay selected information from their inputs SPA1, SPA2 and SPL1-SPL8 to the central unit P2 which contains analysis unit EXAM. Control COM also supplies excitation signals STi to the circuit under test, these being equivalent to normal operating conditions. The digital signals (logic levels or pulses) at the digital test points PL1-PL8 pass via circuit TRANS which converts them to logic levels and feeds them to the multi-plexers MULT. The analogue test point signals are compared to reference levels in comparators El, E2, stored Ml, M2 and also fed to the multi-plexers. The selected information is passed to analysis unit EXAM which compares the results to a list TAB representing correct responses and fault responses. If a fault response is detected, a stored dictionary DIC is consulted, which provides an identification of the fault. If no fault is found, the stored programme progresses to monitor other test points or alter the input conditions.

Title: Improvements in hydraulic braking systems
IPC: B60T13/24
Filed: 1961-11-28
Abstract: 971,827. Hydraulic brakes. BENDIX CORPORATION. Nov. 28, 1961 [Dec. 13, 1960], No. 42542/61. Headings F2E and F2F. An hydraulic internal-shoe drum brake system, Fig. 1, has two shoes 10, 12 actuated by two cylinders 18, 20 interposed each between one pair of adjacent ends of the shoes, each cylinder being connected to a separate pressurizing chamber of the master cylinder B which is so arranged internally that upon failure of one of the two actuating systems so formed, the other remains operative. There may be pneumatic pressure intensifiers C in the brake pipes. The ends of the shoes rest on fixed abutments 22, 24, the self-wrapping action of the shoes ensuring that they pivot thereon about one end; the other ends resting, in the inoperative position, on adjusting screws 26, 28. The master cylinder B, Fig. 2, has two pressurizing chambers 42, 44 delivering to brake pipes through outlets 50, 52, respectively; an outer piston 48 actuated by the brake pedal; and an inner free piston 46. The outer piston has a boss 66 which engages the piston 46 if pressure fails in the chamber 44. Each outlet 50, 52 is provided with a pressure-retaining check valve 116 comprising a rubber diaphragm 118 and metal disc 120. An additional disc check valve 132 is provided in the outlet 50 further to restrict return flow to the chamber 42. A reservoir 78 replenishes chamber 42 through passage 82 and valve 88, which opens when the piston 46 is retracted. It also replenishes chamber 46 through the tilt valve 104, and follow-up chamber 62 through tilt valve 104<SP>1</SP>, the valves 104, 104<SP>1</SP> being opened by contact of the stem extension 114 with piston 48 as shown. When the piston 48 is retracted, liquid is forced under pressure from the follow-up chamber 62 through passages 130 round the seal 58 into chamber 44; an equivalent effect being produced in the chamber 42 by the valve 132. Upon repeated stroking of the brake pedal a pumping action takes place. The pressure intensifier C, Fig. 3, is of the type described in Specification 690,589 and has an inlet from the master cylinder at 142 communicating with chamber 144 behind hydraulic piston 146 and with the back of the control valve actuating piston 148. When the piston 148 moves to the left, it closes valve 160, cutting off control chamber 168 from chamber 166 which is constantly at atmospheric pressure, and opening valve 156 to admit pressure air from the inlet 170. This pressure is communicated through pipe 172 to the back of piston 150, facing the piston-rod 176 and hydraulic cylinder 146 into the outlet chamber 178 to displace hydraulic fluid into the brake pipes. If pressure air fails, piston 146 will be displaced by direct action thereon of fluid from the master cylinder. The piston 146 has a check valve 184 to admit compensating fluid to the brake line.

Title: Pressure regulator
IPC: G05D23/12
Filed: 1977-10-13
Abstract: 1537220 Pressure regulator HONEYWELL BV 13 Oct 1977 [14 Oct 1976] 42587/77 Heading G3P A pressure regulator comprises a valve closure member 5 carried by a diaphragm 25 acted on by springs 46, 29 and 30, and a lever 10 acted on by an expansible temperature sensor 17 to act against the bias of the spring 46 to permit the springs 29 and 30 to determine a value of the pressure regulated by the valve 5 which is less than a maximum value set by the spring 46. The regulated pressure is that upstream of the valve 5 and is used to control a main gas supply valve (not shown), the outlet pressure of which acts on the diaphragm 25 in a sense to open the valve 5 (and thus reduce the pilot pressure). Below a temperature which is settable by a knob 22, which moves diaphragm capsule 17 bodily, the valve is held closed by the spring 46 to maintain both the control pressure and the main gas outlet pressure at their maximum values; above that temperature the gas-pressures fall, at a rate determined by the spring 29, to a minimum value determined by the spring 30. Should the temperature continue to rise a blade spring 49 connected to the lever 10 operates a switch 51 to cut off the gas supply.

Filed: 1970-09-07
Abstract: 1322573 Missiles with stabilizing fins MESSERSCHMITT - BOLKOW - BLOHM GmbH 7 Sept 1970 [8 Oct 1969] 42781/70 Heading F3A A rocket comprises stabilizing fins 4, Fig. 2, secured in a retracted position by a locking system which is released by the propulsion unit of the rocket a predetermined time after launching, the time lag being caused by a delay unit interposed between the propulsion unit and the locking system. The locking system comprises a wire 8 encircling the fins. Each end of the wire terminates in a ball 9 which is retained in a recess 21, Fig. 1, of a rod 19 by a sleeve 20. The rod 19 is connected to a piston 17 which is separated from a pyrotechnic charge 12 by a perforated plate 16. The pyrotechnic charge is an anged to be ignited through a passage 13 by the hot propellant gases from the rocket motor and burns through to expose the piston to the pressure of the propellant gases or to the pressure of its own combustion gases. The piston is thereby displaced rearwardly and the recessed end of the rod 19 emerges from the sleeve 20. The fins thus released from the retaining action of the wire 8 are erected by springs 6. The pyrotechnic charge 12 may be replaced by a substance which liquefies or evaporates at elevated temperatures.

Title: Improvement in or relating to exposure control apparatus for photomicrography
IPC: G03B27/80
Filed: 1965-10-11
Abstract: 1,128,808. Photo-electric camera exposure. C. REICHERT OPTISCHE WERKE A.G. Oct. 11, 1965 [Oct. 14, 1964], No.43051/65. In a photo-micrographic apparatus where a subject is photographed through a microscope and a photo-cell views the microscope image, the exposure time is determined by balancing a circuit containing the photo-cell either manually or automatically which simultaneously adjusts the time constant of an R.C. timer controlling the time of opening of a photographic shutter. The photo-cell may be of the photo-voltaic type whose emf is balanced against another voltage or be of the photo-conductive type and be contained in a Wheatstone's bridge circuit. In the arrangement of Fig. 1, light from a microscope directed towards a camera 3a is partially deflected by semi-transparent prism 2 on to a photo-voltaic cell 5. The emf of this cell is balanced against a resistor r i  selected manually by a rotary switch 6. An indicator 7 detects the state of balance and operates one of lamps 35, 38, 36 accordingly. Selection of resistor r i  for balance simultaneously selects by a gauged rotary switch 8 a resistor R i  in the R.C. timing circuit of the shutter solenoid 28. To take a photograph push-button 26 is operated which discharges capacitor 25 through resistors 24 and R i  and the shutter solenoid, upon the discharge current falling to a predetermined value, contacts 27 and 26a previously self-held, now open to close the shutter. Extra capacitors 43 and 42 may be inserted to compensate for the reciprocity low failure and by adjusting the relative coupling angle between rotary switches 6 and 8 the sensitivity of the photographic material can be taken into account.
