Abstract: 1489499 Regulating IC engine fuel supply NISSAN MOTOR CO Ltd 12 Nov 1975 [12 Nov 1974] 46684/75 Heading F1B [Also in Division G3]  The vacuum at a port 32 of a fluidic element 22 receiving fuel from a pump 40 via a port 24 and having a port 30 communicating with the atmosphere, a port 28 communicating with the air induction passage 10 and a port 26 communicating with the float chamber 38, is modified in accordance with the oxygen content of the engine exhaust gases by a solenoid valve 80. In the embodiment shown the valve 80 controls a by-pass 72 around a restrictor 56 in the passage 54 connecting the port 32 to the Venturi 12 in accordance with the signal from a sensor 70 via a controller 86. The valve 80 may control communication of the passage 54 downstream of the restrictor 56, with the atmosphere. The vacuum port 32' of a second fluidic element 22' or vacuum ports of further elements may similarly control fuel flow to the passage 10. The valve 80 may be operated continuously or in an on-off manner by constant frequency pulses produced by a generator 100. The amplified sensor voltage V s  is compared with a reference voltage V sR  to provide an error signal e. The signal e is fed to proportional and integrating controllers 92, 94 providing output signals which are added and fed to the generator 100 containing a generator of triangular pulses and producing an output of variable period rectangular pulses (104), Fig. 5 (not shown).

Abstract: 1398749 Multi-speed gear-boxes DAIMLERBENZ AG 10 Got 1972 [12 Oct 1971] 46687/72 Heading B7H [Also in Division F2] A vehicle having a multi-speed gear-box including a main gear-box 14, a distributing gearbox 13 for driving the axles and disposed near the centre of the vehicle, and an additional gearbox 15, wherein the main and additional gearboxes are arranged on opposite sides of the distributing gear-box, the additional gear-box being on the side facing the engine 11. Engine 11 drives, via shafts 12, 17, a main clutch 16 which is connected to an input shaft 18 of the main gear-box; shaft 18 carries forward and reverse gears 20 and 21 which are connectable to the shaft 18 by a clutch 22. Gears 20 or 21 drive, via an intermediate shaft 23, the gears for the individual speed changes which are mounted on the output shaft 24 of the main gear-box. A planetary gear set 25, having a carrier 27 connected to the input shaft 28 for the distributing gear-box, is driven by a sun gear 26 in shaft 24, and an annular gear 29 of the set 25 can be connected by a clutch 30 either, as a reaction member, to the gear-box casing for speed reduction, or to the carrier 27. As shown in Fig. 1, the input gear 31 of the distributing gear-box is driven by shaft 28, via a sliding clutch 39 having long and short tooth systems 40, 41, and in turn drives intermediate and output gears 34 and 35. Gear 35 is permanently connected to a take-off 36 for the vehicle rear axle, whilst a forward axle take-off 37 may be connected thereto by a clutch 38. If clutch 39 is moved to the left, toothing system 41 disengages and a similar system 42 engages, thus causing the additional gear-box to be engaged and further reduction gearing becomes available, since the distributing gear-box is now driven through the additional gear-box. A sliding clutch 46, similar to 39, is movable to engage either a planetary gear system 45 with an input gear 52 on shaft 28, or to engage the carrier 51 of a further gear system 44 with the sun gear 48 of the system 45. The gear system 44 is driven by input gear 55. The carrier 43 of the system 45 transfers drive via the clutch 39 to the input gear 31 of the distributer gear-box. In another embodiment (Fig. 2 not shown) shaft 28 does not extend into the additional gear-box, a further shaft (57) connectable to clutch 39 by a sliding sleeve, being provided to act as the input shaft.

The hinges 24 are also coupled to extensible telescopic struts 14, the lower ends of which are hinged to the spacecraft 12. For stowage in a launching vehicle the struts 14 are contracted, when the segments 22 form a series of ogives and the reflector 18 is folded, as shown in Fig. 1. When the spacecraft is in orbit the struts 14 are extended by gas pressure, and the segments 22 join in a closed loop, with the reflector 18 assuming a predetermined, preformed shape, such as a paraboloid, as shown in Fig. 4. Each of the hinges comprises a pair of covers 32, 34, Fig. 6, into which the ends of two adjacent segments 22 are secured, and which are pivotally connected by a pin 36 permitting rotation in one plane. The upper hinges 28 only are provided with balls 58 secured on their pins 36 and received in spherical sockets in bushings 62, so permitting rotation in two planes.

Abstract: 1535914 Automatic control of position SONY CORP 20 Nov 1975 [26 Nov 1974] 47837/75 Heading G3R In video playback apparatus, using parallel tracks on a recording medium e.g. tape or disc, a rotary signal pick-up is moved in the direction of a track width in accordance with a tracking error between the pick-up movement and a predetermined trace of the pick-up. In the embodiment shown, the pick-up 13a (Fig. 2) e.g. magnetic, optical or capacitive, is mounted on a member comprising Piezo-ceramic plates 100, 101 with a stainless steel plate 102 therebetween. A tracking error signal w, is applied to input Q to vary the voltage across the plates 100, 101 and thus to change the pick-up position accordingly, up to limits of Œ #h. In Fig. 5, the tracking error signal is used in apparatus having magnetic tape T and rotating, helical scan heads 13a, 13b mounted as above. Signals from sensors 202, 205, having frequencies proportional to tape and head speeds, are phase compared at 204 to provide the tracking error signal for pick-up controller 208, the correction being made if necessary e.g. due to tape slip whilst the pick-up is not reading information from the tape. The pick-up is progressively moved until its maximum value, when the deflection is reduced so that the pick-up scans the next, adjacent track. The parallel tracks may be oblique tracks on tape, or tracks on a magnetic disc. In an alternative embodiment Fig. 5 (not shown), the phase comparator is replaced by a circuit in which a sawtooth waveform is triggered for each tape speed signal from sensor 202, and this waveform is sampled by time delayed pulses from head speed sensor 205, the resultant passing through a low pass filter to control the position of the, or each, pick-up.

Abstract: 1,208,435. Preserving micro-organisms. NATIONAL RESEARCH DEVELOPMENT CORP. 29 Oct., 1968 [1 Nov., 1967], No. 496 79/67. Heading A2D. [Also in Division F4] A method of preserving a specimen (e.g. micro-organisms) comprises drying the specimen under substantially isothermal conditions by heating the specimen in a receptable, partially evacuating the receptacle and controlling the total pressure in the receptacle in such a manner that the rate of loss of heat from the specimen is substantially equal to the rate at which heat is supplied to the specimen, evacuating the receptacle to a higher vacuum after the specimen has been dried and then hermetically sealing the receptacle. In the apparatus shown, ampoules 1 and 7 each containing a specimen, are mounted on manifold 4 which is connected to a gasballasted rotary vacuum pump 5 and aircooled oil diffusion pump 6, heated in hot water bath 11 or a heated fluidized sand bed and partially evacuated. The difference in the temperature of control specimen in ampoule 7 and the water bath is sensed by a thermocouple 9 and this difference is maintained at a substantially constant predetermined value during drying, by controllably feeding air via adjustable needle valve 15 into the evacuating system. The valve 15 is automatically operated in response to temperature difference sensed by the thermocouple 9. When the specimens have been dried the temperature of the specimens rises towards that of the bath and the valve 15 is closed. The ampoules are then automatically raised from the bath and evacuated to a high vacuum. The evacuated ampoules are healed by a high temperature flame.

A dump valve may be fitted and may act as a safety valve if a compressing pump raises the pressure unduly. The dump valve otherwise is normally operated by a signal pressure of air through a port in member 35 which air acts on a seal positioned above the port, lifts the spring loaded dump valve and allows sump to empty. A pressure drop across filter and dessicant bed 50 causes housing 37 to lift as shown by lines 40 and allows air from inlet 58 to pass to outlet 79 since seal 63 is then ineffective.
