Title: Exhaust emission control device for internal combustion engines
Inventor: HANSEN HANS CHRISTIAN
IPC: F02M23/00
Filed: 1967-12-12
Abstract: 1,255,606. Treating I.C. engine charge; spray carburetters. H. C. HANSEN and E. JENSEN. Dec.9, 1968 [Dec.12, 1967; July 26, 1968], Nos. 56420/67 and 35827/68. Heading F1B. Additional air is supplied to the mixture formed in a carburetter under the control of a valve or valves adapted to be actuated in response to movement of the carburetter throttle valve and engine suction. The additional air supply system may be formed in the carburetter or in the form of a member 22 adapted to be bolted between the carburetter 10 and the engine intake manifold and having a bore 28 therethrough forming part of the engine mixture induction duct. In the embodiment shown the member 22 is formed of two plates 23, 24 defining a bore for a valve rod 37 and ducts 31 and 32 communicating with the bore 28 via a recess 35 and slots 34. The valve bore intersects an air inlet 36 and the additional air inlet duct 31 and the rod 37 is connected to the throttle valve shaft 39 by a linkage 42, 43, 44. A groove 40 and a further reduced diameter portion of the rod 37, which co-operates with an adjustable screw 45 in the idling position of the throttle valve 14, are moved into register with the inlet to the duct 31 as the throttle valve is opened and allow maximum air-flow through the duct at certain throttle valve positions, Fig.4 (not shown). The duct 32 communicates with a chamber (59), Fig. 3 (not shown), containing a member (51) which is spring- biased upwardly into contact with a lever (51) which is spring-biased downwardly. The chamber is closed by a diaphragm (56) coupled to the member (51) which, when subject to a predetermined vacuum on engine over-running through the duct 32, moves the member downwardly so that a lug (54) on one end of the lever (51) engages a groove 41 in the rod 37 and holds the rod with the groove 40 in register with the inlet to the duct 31. The rod may be held by lever (98), Fig.5 (not shown), coupled to a piston (104) which is subjected to the vacuum in the duct 32. The vacuum operated device 50 may permit a spring- biased lever (76), Fig. 6 (not shown), to open a valve (80) communicating with the duct 31. In a further embodiment, Figs.7 and 8 (not shown), a pressure responsive device (50) acts on a spring-biased lever (76) which opens an additional air inlet valve (80). The spring-biasing in the device (50) is adjusted so that the valve (80) is partially opened at idling and open to allow maximum additional air-flow at over-running. A leafspring (90) is mounted on the lever (76) to be engaged by the throttle valve actuating lever 16 when the throttle valve is fully open to open the valve (80).

Title: Matrix four-channel decoding system
IPC: H04H20/89
Filed: 1974-08-15
Abstract: 1447814 Quadraphonic decoders; gain control SANSUI ELECTRIC CO Ltd 15 Aug 1974 [20 Aug 1973] 36034/74 Heading H4R In a 2-4 quadraphonic decoder in which the matrix coefficients are automatically varied according to the instantaneous amplitude relationship between the directional components in the two composite input signals, the decoded front and rear channel pairs are fed to respective mixers 48, 49 which only mix the low frequency components (i.e. <500 Hz) without significantly affecting the high frequency components. For low frequencies the front mixer outputs correspond to the sum of the composite input signals and the rear mixer outputs to the difference. The provision of the mixers is tantamount to fixing the coefficients f=b=0 and l=r= 1 in the decoder of Specification 1,434,471. (Fig. 1). In Fig. 4, at low frequencies the capacitive impedances are high and mixing occurs via R12, R13 whereas at higher frequencies the mixing path R12, C12 provides an attenuating low pass filter. The high frequency level is reduced by 6 dB to produce a flat response by R12 in combination with the output impedance of the decoder. The circuit admits of integration and may alternatively be composed of integrated differential amplifiers. Variable gain amplifiers performing the function of the above coefficients consist of a gate-controlled FET (Q2, Fig. 2, not shown) shunting an emitter current source (60) so that low frequency gain is zero but high frequency gain is RC limited.

Abstract: 1,242,987. Thermal regenerators. FORD MOTOR CO. Ltd. 4 Aug., 1970 [2 Sept., 1969], No. 37481/70. Heading F4K. In an annular disc-shaped regenerator core 10 of ceramic material comprising a plurality of closely adjacent passages 12, the inner and outer peripheral regions 18, 20 of the core which, in use, bear against and are slidable on stationary seals 26, 28 in a gas turbine engine housing 30 are provided with a lubricating composition. The lubricating composition is prepared by mixing a particulate solid refractory material such as zinc oxide with a liquid such as water and the resulting mixture is applied to the core in narrow bands 22, 24 and fills the openings of the the passages bearing on the seals 26, 28. During operation, wear of the passage walls exposes the lubricating composition to the surface of the seals and greater amounts of wear expose greater amounts of lubricant until a balance is achieved between the lubricating properties and the wear rate. To produce a regenerator core in which the lubricating composition is maintained in place at extremely high temperatures, coatings of an aqueous solution of zinc nitrate may be applied to the zinc oxide which has been presintered, the core being heated between each coating to convert the zinc nitrate to zinc oxide.

Abstract: 1405615 Photo-detectore fire alarms CHUBB FIRE SECURITY Ltd 2 Aug 1973 [11 Aug 1972 14 Nov 1972] 37633/72 and 52587/72 Heading G1A [Also in Division G4] A fire alarm comprises a solid state source 10 emitting pulses of radiation, a detector 20 for receiving radiation passed through intervening gaseous medium, a frequency selective circuit 24 and an alarm circuit 28-36 responsive to an amplitude modulation present in the received signal and caused by variations in the refractive sides of the medium due to the heat of a fire. The photo-detector 20 has a standing bias applied to it or illumination by a subsidiary source to mimimize variations due to changes in the ambient light. The radiating source, e.g. a Gallium Arsenide diode is pulsed by about 1KHZ from devices 12, 14 and the frequency responsive circuit 24 is arranged to select a pulse signal having a frequency based on the rise time of the pulses of radiation. The effect of mains flicker is reduced in the above manner and the effect of other extraneous signals is reduced by emitting a pulsed instead of a continuous radiation. A further frequency responsive circuit 28, 30 is arranged to respond only to a band of modulation frequencies superimposed on the radiated pulses and caused by hot gases in the invervening medium. The output of the circuit 28, 30 is coupled to an alarm circuit 36 via a time delay 34 to prevent triggering by transient thermal phenomena. The arrangement also includes a circuit 38-48 which detects the presence of smoke by comparing at 40 the amplitude of signal detected during one period with the amplitude sampled and stored during the previous period. A further circuit 50-56 responds to a condition indicative of a fault or permanent obscuration of the radiated beam. An alarm circuit Fig. 6 (not shown), includes separate warning lamps associated with relays which become energized or de-energized to activate the above lamps. The source and detector may be kept at opposite ends of an enclosure or kept at the same end and associated with a reflecting mirror. Figs. 2-6 (not shown), relate to individual circuits usable in the arrangement of Fig. 1. The alarm may also operate as or incorporate a smoke detector.
