Title: Improvements in or relating to sheet stacking devices
Inventor: HIRST PETER DAVID
IPC: G06K13/12
Filed: 1958-02-03
Abstract: 903,991. Stacking sheets. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Dec. 19, 1958 [Feb. 3, 1958; July 17, 1958], Nos. 3437/58 and 22964/58. Class 100(1). Sheet-stacking apparatus includes a hopper for holding a stack 1 of sheets, a pair of generally cylindrical rollers 3 spaced apart with their axes parallel and lying in a plane parallel to the plane of the sheets in the stack, a recess 6 extending longitudinally along the surface of each roller, and means for rotating the rollers in synchronism, the rollers being so arranged that at one point in their rotation the recesses 6 are positioned to receive and support opposite edges of a sheet or sheets fed towards the rollers in a plane parallel to the plane of the sheets in the stack 1 to form thereby a sub-stack 7 spaced from one face of the stack, and that further rotation of the rollers moves the substack into the hopper. The hopper is formed by side plates 2 and extensions 5 of the side plates extend into circumferential grooves in the rollers 3 to prevent the lowermost card from slipping sideways out of the stack. When the rollers are in the position shown, one or more cards are fed thereto so that marginal portions of the cards engage in the recesses 6 in the rollers. The rollers are then rotated through 180 degrees in the direction of the arrows 8 so as to transfer the card or cards in the recesses 6 to the bottom of the stack 1 and bring further recesses 6a into position to receive a further card or cards. This embodiment may be used for stacking horizontally as well as vertically if a suitable support, e.g. a spring-pressed plate, is provided for the main stack. The rollers 3 may have the noses 9 above the recesses 6, 6a omitted in which case the stack 1 is supported in the hopper by spring steel fingers projecting inwards from the side plates 2. In another embodiment described in the second Provisional Specification, but not in the Complete Specification, the sub-stack is built up on a platform situated below the bottom of the stack. When the sub-stack is complete a number of fingers pass through gaps in the platform to engage the bottom of the sub-stack and move it upwards until the top of the sub-stack is supporting the main stack of cards in the hopper the fingers move the bottom card of the sub-stack beyond spring or camcontrolled latches on the hopper wall and then are moved downwards before raising a further sub-stack.

Filed: 1965-01-27
Abstract: 1,033,493. Circuits of magnetic storage elements. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 27, 1965 [Jan. 30, 1964], No. 3581/65. Heading H3B. [Also in Division G4] Magnetic storage cores K1-Kn, Fig. 1, each with an input winding N3, a read-out winding N1 and an output winding N2, have the readout windings connected in series between a first current pulse source S1 and a plurality of parallel output circuits, each consisting of a respective output winding, a rectifier G1-Gn and a load A1-An, the application of a current pulse from S1 to windings N1 being of limited duration so as to partially reset the flux of a core previously set by input winding energization, while a further current pulse from a second current pulse source S2 and acting in further windings N4 completes the flux resetting after the first current pulse terminates. In the switching circuit shown, a core, while resetting, induces a voltage in the associated output winding N2 which biases the rectifier in the output winding circuit in the forward direction. This permits a current pulse from the first source to pass to a selected load. When the current pulse ceases, the load current terminates, and the pulse from the further current source serves to complete the core resetting without providing an output. In an application to shift registers, Fig. 2, the cores K1-K8 are arranged in odd and even groups which are pulsed alternately by respective first and further pulse sources SA, SA<SP>1</SP> and SB, SB<SP>1</SP>. Each output winding N2 on a core is connected in series with an input winding N3 on the next core of higher order, a current directed through that load circuit by a voltage induced in winding N2 causing the adjacent core to be set.

Title: Improvements in and relating to the control of thermionic devices
IPC: H03F3/22
Filed: 1936-02-08
Abstract: 466,831. Valve amplyifying and modulating circuits. BRITISH THOMSONHOUSTON CO., Ltd. Feb. 8, 1936, No. 3872. Convention date, Feb. 9, 1935. [Class 40 (v)] The anode supply voltage, and the grid bias, of an amplifier or modulator valve operating on the straight part of its characteristic curve, are varied automatically in response to the volume level, varying at syllabic frequency, of the audio signals impressed thereon ; the object being to increase efficiency by economizing anode current. The Figure shows a choke modulating-circuit in which the carrier-wave output of the valve 11 is modulated by a valve 18, the two anode circuits being fed from the same source of high-tension current through a common choke 31. The grid of the valve 18 is fed with modulating- current by a source 13 and amplifier 14 through a transformer 16. Modulating-current also feeds a rectifier 32 the output of which is smoothed by a filter 33 designed to remove the modulating frequencies but to retain syllable frequencies, which appear as variations of voltage across the resistance 35. Anode voltage for the valves 11, 18 is supplied by mains rectifiers 23, 24 shown as full-wave rectifiers of three-phase supply current. The voltage across the resistance 35 is applied through a polarizing-source 36 to grids 27 in the rectifiers 24, thus causing variation in the D.C. output of the rectifiers. This is applied to the valves 11, 18 through a smoothing circuit 28 designed to remove the supply frequency, but to retain the lower syllablefrequency caused by the grids 27. In this way the supply current to the valves 11, 18 is raised and lowered at syllable frequency. A self-biassing resistance 20 shunted by a condenser 21 may be arranged to cause a corresponding variation of grid bias. A voltagelimiting diode 38 is connected across the resistance 35 in series with a fixed voltage source 39. The system has the effect of reducing carrier strength when the modulating signals are weak. The Specification as open to inspection under Sect. 91 describes modifications in which only the anode voltage, or only the grid bias, is varied at syllabic frequency. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in and relating to the gasification of solid carbonaceous fuel
Inventor: HEBDEN DENNIS
IPC: C10J3/08
Filed: 1963-01-31
Abstract: <PICT:1070009/C4-C5/1> A shaft gasifier for the gasification of a static bed of an ash-containing solid carbonaceous fuel comprises a plurality of tuyeres distributed round the lower part of the inner wall of the shaft, means for causing gasifying agent to issue simultaneously from some of the tuyeres at one rate and from the remaining tuyeres at a different rate, valve means for changing the rate from each tuyere from one of the rates to the other, and automatic timing means for the valve.  The gasifier is operated at a temperature such that the ash collects in liquid form beneath the fuel bed, from where it is continuously discharged.  The velocity from some of the tuyeres is chosen to give preferential central gasification and that from the remainder to give preferential peripheral gasification of the fuel, and each change is made to give no alteration in the rate of supply of the gasifying agent from all the tuyeres collectively.  This may be effected by operating half the tuyeres at each chosen velocity and by simultaneously changing both halves from one to the other velocity.  The gasifying agent may be oxygen, air, oxygen-enriched air, a mixture of any of the foregoing with one or both of steam or CO2, or hydrogen.  Atmospheric or superatmospheric pressure may be used.  As shown, six tuyeres, designated 5 and 6, projecting into the shaft are supplied by pipes 7 and 8 with gasifying agent obtained from main supply pipe 9 via branch pipes 10, 11, 12 of which branch pipe 11 leads to two-way valve 13. Valve 13 communicates either with pipe 14 or with pipe 15 and in each of pipes 10, 12, 11 is a nozzle or orifice plate 16 which controls the rate of supply of gasifying agent.
