In a continuously operating ice-cream freezer and dispenser device comprising a chamber 16 cooled by an evaporator 22 and provided with a rotary helical beating device 17 adapted to transform liquid mix Q in a vat 14 into a pasty material and to urge the pasty material towards a dispensing outlet 36 located at the forward end of the chamber, pressurized air for emulsifying the pasty material into a foamy ice cream is supplied from the space above the mix to the chamber 16 through a nozzle 38. The air in the space above the mix Q enters an inlet 45 of a rotary or diaphragm pump 42, driven by a separate motor or by a cam 47 mounted on the belt-driven shaft 20 of the beating device 17. The air compressed by the pump passes through a non-return valve 39 before flowing through the nozzle 38. A small part of the air is discharged with the ice cream through the outlet 36 and the remaining part passes along the chamber 16 and flows upwardly through a vertical passage 15 to bubble through liquid mix Q. The space above the mix Q is closed by a substantially air-tight hinged cover 11 and hence the majority of the air is recirculated. Additive air may enter the space above the mix through a filter or air purifier. A casing 10 having perforated walls 49, 50 encloses the device which includes a compressor P and a condenser R.

Abstract: 1298330 Controlled rectifiers TOKYO SHIBAURA ELECTRIC CO Ltd 13 Oct 1970 [13 Oct 1969 7 Nov 1969 22 Nov 1969] 48657/70 Heading H1K In a PNPN controlled rectifier the cathode region, formed in one face of the P type gate region, has portions of that region extending through it to said face where they are contacted by a gate electrode spaced from the overlying cathode electrode by a layer of solid insulation. In one embodiment (Fig. 1A) gate electrode 5 which is comb-shaped is interdigitated with the cathode region and its spine 6 disposed along one edge of cathode electrode 7. Alternatively it consists of an annulus with radial spokes extending inwardly beneath a circular cathode electrode. In another arrangement it has a central annulus with outwardly extending spokes each with arcuate offshoots, which lie beneath an annular cathode electrode. In another form the gate has a central spine with teeth extending normally or obliquely from it on both sides, only one end of the spine emerging from beneath the circular cathode. All these embodiments may be modified by providing an auxiliary cathode region which is shortcircuited to the gate electrode and lies between the cathode region proper and a second gate electrode. In the Fig. 10A embodiment, an auxiliary cathode region continuous with the cathode region proper is used, a thinner high resistance portion dividing the auxiliary region contacted by gate electrode 6 from the main region contacted by cathode 7. In a modified form a circular cathode region and generally annular gate electrode with radial spokes is employed. Another modification is a variant, Fig. 1A, in which the cathode region has a finger which extends to contact spine 6 of the gate electrode and an auxiliary gate contact is provided on the side of the spine opposite the finger. The structures are produced by conventional processing steps.

Abstract: 1,273,320. S.C.R. switching circuits. D. D. BOWEN. 14 Oct., 1970, No. 48736/70. Heading H3T. [Also in Division G4] In a "first up" alarm indicator, the particular contacts first actuated is memorized in a thyristor store, the appropriate lamp is lit and all other lamps inhibited. If contact T2 is opened a trigger voltage from potentiometer R1, R2 is applied to the trigger electrode of S2 rendering it conducting. Capacitor 6 then starts to charge via diode D1 and resistance R. When C is charged transistor TR1 is switched to the conducting state permitting lamp L2 to light. This circuit prevents actuation of the lamp for transient effects. As soon as S2 conducts it drives the cathodes of the remaining thyristors positive, so that trigger voltages cannot make these thyristors conduct, and therefore inhibit the illumination of the remaining lamps.

Filed: 1967-11-06
Abstract: 1,202,397. Power steering. TRW Inc. 6 Nov., 1967, No. 50422/67. Heading B7H. A valve arrangement is adaptable for use either in closed-centre or an open-centre hydraulic circuit. For the former the valve comprises a housing with a first bore 31 containing a valve spool 32 with cam surfaces 50, a second bore 64 with a valve seat 74 and a complementary poppet valve 75, to control fluid flow between an inlet side 79 and an outlet side 89 of the valve 75, a first passage between a fluid chamber 85 and the outlet side 89 of the valve 75, and containing a check valve 92 which is normally biased close, a second (helical) fluid passage 83 between the inlet side 79 and the chamber 85, and means to displace the spool axially when one of the cam surfaces 50 operates actuating means 98, 97 to open the check valve 92, causing the poppet valve to open and permit fluid flow from the inlet to outlet side of the poppet valve. As shown, applied to a telemotor steering system in Fig. 1, a manual control pump 24 communicates with chambers 38, 39 at opposite ends of the spring-centralized spool 32 through grooves 51, 52 and bores 60, 46 and 61, 45 respectively of the spool 32; a servomotor 25 is connected to housing grooves 68, 69; housing grooves 71, 72 communicate with a fluid reservoir 23, and a pressure pump 22 is connected through the poppet valve with a central housing groove 66. In the central valve position the pump pressure acts in the chamber 85 to hold the poppet valve closed, but when the pump 24 is rotated a pressure differential is produced between the chambers 38, 39 displacing the valve spool when a cam surface lifts the ball 98 and hence the check valve 92 causing a drop in pressure in the chamber 85. The now unbalanced inlet pressure in chamber 79 acts on shoulder (80) (Fig. 2, not shown) of the poppet valve to lift it, permitting pressure fluid to the pass valve seat 74 to the housing groove 66. The displaced valve directs the pressure fluid through the manual pump 24 to one side of the servomotor 25 and connects the other side to the reservoir. When the valve spool is centralized by stopping the pump 24, the check valve 42 closes, permitting pressure to build up in the chamber 85 to close the poppet valve. In the alternative open-centre hydraulic system in Fig. 6, the poppet valve connects the outlet of the pressure pump 22 to the reservoir when the valve spool in its central position, but closes this connection when the spool 32 is displaced to increase the pump outlet pressure which is communicated through a line 131 to the central housing groove 66.

Abstract: 1,144,743. Change-speed control. CLAYTON DEWANDRE CO. Ltd. 6 Oct., 1967 [16 Nov., 1966], No. 51348/66. Heading F2D. [Also in Division E2] In a vehicle gear change mechanism in which a hand lever actuates a series of fluid pressure ratio shift control valves a fluid pressure operated member is arranged, upon an establishing movement of the lever, to hold the latter in the gear-engaged position and also, if the pressure in the system falls to a predetermined minimum value, to automatically return the lever to the neutral position. In the system shown air from an engine-driven pump 80 is supplied to a reservoir 83 from which it passes by a line 84 to the shift control valves 55 connected by lines 87 to the gear-box 88, and by a line 89 to a door actuator 90. A second line 85 from the reservoir 83 includes a low pressure protection valve 86 and leads to inlets 44, 45 of valves 37, 38 controlling the lever locking mechanism. The hand lever 13 which is movable along a central gate slot 14 in a cover 12 for gear selection and rotatable about a pivot 18 for establishment has a depending Y-shaped arm 70 for operating the shift control valves 55. In addition it has arms 24 engaging pins 25 on a cross-shaft 22 housing plungers 28, 30, the ends of which, in the neutral setting shown, are spaced from the valves 37, 38 so that the air pressure at inlets 44, 45 is communicated through valve bores 51, 52 to the opposite ends of cross-shaft 22 to balance the latter and hold the lever 13 in position. When the lever is moved to a gear-engaging position, the arm 70 operates the appropriate shift valve 55 and at the same time the plunger 28 or 30 located above the operated shift valve moves against the end of valve 37 or 38 to close the bore 51 or 52 and open the valve to exhaust port 46 or 47, so that the differential air loading then acting on cross-shaft 22 is transmitted by pins 25 to lever 13 which holds the shift valve fully open and is itself held in the gear-engaged position. In the event of the air supply pressure falling to the minimum value, the valve 86 opens to vent line 85 to atmosphere so that the pressure supply to inlets 44, 45 is cut off, whereby loading springs 31, 32 on plungers 28, 30 act to centre cross-shaft 22 and thus automatically return hand lever 13 to the neutral position. In this condition gear may still be engaged by appropriate setting of the lever 13 and holding it in position by hand. To engage reverse gear it is necessary to withdraw a retractable stop (91), Fig. 3 (not shown), by a knob (95) to allow full engaging movement of the valve operating arm 70, the stop being returned automatically by a spring (92) when reverse gear is disengaged. For door operation the hand lever 13 is raised against the action of a spring 101 until the lower end of a sleeve 96 clears a raised baulk lug (95) on the edge of the end gate slot D, Fig. 1 (not shown), before being fully engaged in the slot to operate the appropriate valve 55.
