Title: Address decode logic for a semiconductor memory
IPC: G11C8/10
Filed: 1971-12-20
Abstract: 1340758 Decoders NORTH AMERICAN ROCKWELL CORP 20 Dec 1971 [18 Dec 1970] 59042/71 Heading G4H An address decode logic system comprises a plurality of decoded-address lines 72-79 (columns) in a semi-conductor substrate, a plurality of input lines 41-46 (rows) representing the bits of an address to be decoded, the address lines being associated in pairs, the two lines of each pair having addresses which differ in one bit position only and being connected to a precharge line 44 through respective FETs 81, 92, 95, 96, 99, 100, 103, 104 whose gate electrodes are connected to two of the input lines pertaining to the complementary values of one bit position, means for applying first and second voltage levels to the recharge line during a recharge interval and an ensuing evaluation interval respectively, and means for rendering both said FETs conductive in the precharge interval, whereas only one is conductive in the evaluation interval, as determined by the address being decoded. Stray capacitances are charged up by a precharge signal applied at the points labelled #1, then the address bits in true and complement forms Al, A1, A2, A2, A3, A3 discharge every column line but one, the inputs A1, A1 rendering a FET (e.g. 81 or 92) in one of each pair of columns conductive, and the other address bits rendering conductive FETs (e.g. 93) connecting the two columns of various pairs. The non-discharged column then provides an output via a respective FET 55-62. The output addresses one dimension of a memory, the other dimension being addressed similarly.
Patent GB-590497-A (GB)
Abstract: 590,497. Lubricating BENDIX AVIATION CORPORATION. Nov. 29, 1944, No. 23870. Convention date, Oct. 30, 1943. [Class 12 (iii)] Apparatus in which a rotary shaft passes through the wall of a sealed oil-containing space with sealing means surrounding the shaft at its point of entry has a venting means provided for such space comprising an axially extending duct of varying diameter in the shaft which duct is closed at one end but open to atmosphere at the other end externally of the sealed oil-containing space and which within the sealed oilcontaining space communicates therewith by an offset radial duct. The Figure shows the application to the sealed oil-space 31 for the lubrication of a bevel gear drive 38, 39 to a magneto generator for the ignition system of an aircraft internal-combustion engine. The shafts 33, 35 are sealed at their passage through the oil containing space by a carbon ring 45 carried on a flexible diaphragm support 42, 43, 41 subjected to spring pressure so that the carbon ring is forced against an outside collar 46 on the shaft. The shaft 35 has an axial duct 50 stepped in diameter and with radial offsets 51 at the portion with largest diameter whereby the sealed oil-space 31 is always at the pressure of the outside air and thus no pressure difference exists to cause an outward leak of the oil past the sealing ring 45. Oil is filled to not more than the level of the bottom of the smallest portion of shaft duct 50 so that none can escape through the duct; when the engine is running the centrifugal pump effect of the radial ducts 51 prevents entry of oil even on banking of the aircraft. The shaft 35 is shown with a helical groove 49 on its periphery cooperating with an adjacent sleeve 48 which arrangement while permitting passage of air acts as a reserve-flow pump to prevent oil reaching the end space adjacent the carbon sealing ring.

Filed: 1967-12-29
Abstract: 1,170,180. Powder dispensing projectiles. AAI CORP. 29 Dec., 1967 [30 Dec., 1966], No. 59232/67. Heading F3A. [Also in Division F1] A powder dispenser comprises a body 13 of plastics material, e.g. nylon, containing the powder 25, a piston 27 movable by gaseous pressure produced by an explosive charge 49 to discharge the powder, and a shear-type closure member 17 which is sheared by the movement of piston 27 acting through a lost motion linkage 31. In operation, a handle 63 is released by removing a pin 65, a spring-loaded striker 67 then striking a primer 61 which ignites a timedelay fuse 55. An explosive propellant charge 49 is fired by fuse 55 and blows out a cover 51 and shear disc 43. The propellant gases move piston 27 towards closure member 17. When the gap between projections 17a, 27a in tube 29 of linkage 31 has closed, member 17 is sheared off and discharged together with a protective cover 23 and tube 29, followed by the powder. A shear portion 27b on piston 27 is sheared by the gas pressure if skirt 27c seizes. The lost motion linkage may alternatively comprise a solid rod between cup portions of closure member 17 and piston 27, or tube 29 may be fixed to either member 17 or piston 27.

Title: Float chamber carburettors for internal combustion engines
IPC: F02M5/08
Filed: 1970-12-21
Abstract: 1312159 Spray carburetters SOC INDUSTRIELLE DE BREVETS ET D'ETUDES 21 Dec 1970 [19 Dec 1969] 60487/70 Heading FIB I. C. engine carburetter has a float chamber from which fuel is fed to a jet in an air inlet pipe by the difference in pressure between the airspace above the fuel and at the jet which is situated downstream of an air-filter and upstream of a driver-operated throttle valve, there being a valve which connects the air-space to either the air inlet pipe downstream of the filter when the throttle is opened beyond a pre-determined position, or to a point outside the inlet pipe when the throttle is not opened as far as the pre-determined position, there also being provided a temperature sensitive device which keeps the air-space connected to the point outside the inlet pipe when the temperature of the device exceeds a pre-set limit even though the throttle is opened beyond the pre-determined position. The air-space above the fuel in float chamber 1 is connected by a channel 6 to a chamber 7 having two valve seats 8 and 9 and a valve 12 which can close on to either of the seats. When the valve is closed on to seat 8, the channel 6 communicates with atmosphere through an orifice 11. When the valve is closed on to seat 9, channel 6 communicates through pipe 10 with the air-inlet pipe 3. The valve is biased towards seat 8 by a spring 20 and towards seat 9 by a stronger spring 19. A rod 13 connects the valve 12 to a lever 16 which is freely rotatable about the spindle 5 which carries the throttle valve 4, the connection being by a collar 18 which allows lost motion between the rod and lever. Fixed on the spindle 5 is a lever 14 carrying a pin 15 which engages the lever 16 as the throttle valve approaches its closed position, and turns the lever 16 in the same direction. The temperature sensitive device comprises a bi-metal strip which is clamped at one end by screws 23 and has a free end 21 which engages beneath a lug 24 on the lever 16. Operation. When the carburetter body is at its normal operating temperature and the throttle is allowed to close, pin 15 on lever 14 rotates the lever 16 so that spring 19 is compressed and valve 12 is closed by spring 20 on to seat 8. The air-space above the fuel is then vented to atmosphere. If the throttle is opened soon afterwards, spring 19 re-asserts its control and closes the valve 12 on to seat 9 so that the air-space is vented to air-pipe 3. Alternatively, when the engine is hot and is either stopped or idling, the temperature in the engine compartment heats the strip 22 so that end 21 moves upwardly and holds the valve 12 against seat 8. The air-space is then subject to atmospheric pressure which is higher than the pressure existing in the inlet pipe 3 so that the engine receives an enriched mixture for a short time.
