Title: Improvements in high frequency modulating systems utilising electron beam discharge devices
IPC: H01J25/06
Filed: 1940-09-27
Abstract: 544,850. Electron oscillators and circuits therefor; coil-less resonators. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 27, 1940, No. 14631. Convention date, Sept. 27, 1939. Addition to 541,271. [Classes 39 (i) and 40 (v)] The power output of a velocity-modulated ultra high-frequency electron discharge tube is modulated by varying the potential of the collector electrode 18, Fig. 1, or an electrode 19<SP>1</SP>, Fig. 2, in front of the collector 181. The tube is of the kind described in the parent Specification having a number of electrodes 23-27 surrounding the discharge tube 10 and spaced apart to form gaps; end plates 35, 36 and an outer conductive shell 33 complete the resonator. The capacity of the gaps is variable by the rings 28-31. Power is taken off by the coaxial line 39, 40, Fig. 1, from the electrode 25 ; or a loop 50, Fig. 2, is carried by the coaxial line 51, 52 which loop may be turned about its own centre to vary the inductive coupling of the loop. The beam is produced by a gun 15 and moves through electrodes 12 in the drift space opposite the ends of the resonator and at the same potential. The lengths of the electrodes 23 ... 27 is designed so that the energy imparted to the beam at the gaps shall be cumulative. Electromagnets, not shown, form the beams. In the arrangement shown in Fig. 1 the electrode 19 is at a potential lower than that of the collector 18 to suppress secondaries. If the potential of the collector 18, Fig. 1, or the electrode 191 and collector 181, Fig. 2, is suitably fixed some of the low velocity electrons in the beams moving towards the collector will be repelled and returned to the drift space to effect a variation in the interaction between the beams and the oscillations in the resonator. By applying a signal from a source 42, Fig. 1, or 67, Fig. 2, through valves 43 or 61 to the collector 18 or electrode 191, the potential at the end of the beam travel is varied and the reflection of electrons is varied to give a modulated output.

Title: Improvements in or relating to coated cereals
IPC: A23G3/26
Filed: 1954-05-19
Abstract: Ready-to-eat cereal bodies are coated with a hard glaze which does not become sticky in moist air by distributing over the surfaces of the cereal bodies an aqueous syrup containing 60-85 per cent of dissolved solids consisting of sucrose predominantly and 1-8 per cent of non-sucrose sugar and then drying the syrup-coated bodies to 2-3 per cent moisture at such a temperature and for such a time that the amount of invert sugar formed does not increase the non-sucrose sugar to above 8 per cent of the coating.  The drying may be for 7-8 min. at 275 DEG -300 DEG F., 15-20 min. at 225 DEG -250 DEG F., or 20-30 min. at 200 DEG -225 DEG F.  The syrup may contain a viscosity-increasing agent, e.g. dextrin, gum, methyl cellulose, carboxymethyl cellulose, dextran or gelatinized maize, waxy maize or tapioca starch.  The coating may constitute 25-60 per cent of the coated cereal product.  Examples are concerned with treating corn flakes with a sugar syrup containing honey, salt and sodium acetate and with treating puffed wheat with a sugar syrup containing maize dextrin, honey, salt and sodium acetate.

Patent GB-977469-A (GB)
Title: Process for the production of compounds for semi-conductor uses
IPC: C01G1/12
Filed: 1961-04-24
Abstract: Binary compounds for semi-conductor uses are made by reacting a vapour of one element of the binary compound or a vapour of a compound of such element, and the other element in liquid form, in the presence of a molten zone of the binary compound product freely supported on or by a carrier and not in contact with the walls of the confining vessels.  An element of the fifth, sixth or seventh main <PICT:0977469/C1/1> group of the Mendel<\>aeeff Periodic Table or a compound thereof, individually or in admixture is used as a starting material to provide the vapour.  A monocrystalline or polycrystalline seed crystal, having the shape of a rod or tube at the commencement of the process, is used to form the molten body or zone.  The non-volatile material is supplied from above, from the side or from below the molten zone in liquid or solid form, said solid form being melted before introduction to the molten zone, and the non-volatile material is brought to the molten zone by means of gravity, centrifugal force or magnetic and/or electric forces.  As the reaction proceeds, the seed crystal is slowly withdrawn from the reaction zone, so that a solid object of a desired shape is built up. The shape is governed (a) by the type of seed crystal used, i.e. rod or tube, and (b) by the shape of the melt zone as controlled by supporting magnetic fields. Fig. 1 shows an apparatus suitable for the production of GaAs.  1 is a titanium block which serves as a thermostat, 2 is a holding rod, mounted rotatably so as to be movable in an axial direction; support 3 carries a seed crystal 4 consisting of GaAs. The amount of As for producing a rod of GaAs is applied to the inside wall of vessel 5, and the vessel is then mounted by known means on block 1. The block is then heated to 645\sB5 DEG C. by a heating device (not shown), the temperature being controlled by thermocouple 6.  The vessel 5 is evacuated and a temperature between 700 DEG  and 800 DEG C. maintained.  The arsenic sublimes on to block 1, the temperature of which is used to control the arsenic vapour pressure in the vessel.  The upper end of 4 is melted by the high-frequency coil 7.  The gallium contained in vessel 8 is supplied in drop form through nozzle 9 to the molten meniscus 10.  As the GaAs is formed in the meniscus from the dropped on gallium and the arsenic vapour, the rod 2 is gradually withdrawn. An electromagnetic supporting field simultaneously generated by coil 7 prevents the molten meniscus dropping over the side, and a rod of GaAs is slowly produced.  The process is said to be of use in the formation of AIBVII, AIIBVI, AIIIBV compounds, and also nitrides, phosphides, arsenides, antimonides, oxides, sulphides, selenides, tellurides, halides, borides, carbides, silicides, germanides, stannides, other intermetallic compounds and mixtures thereof. The introduction of the liquid non-volatile material from below the molten zone is illustrated in Fig. 2 (not shown).

Abstract: 1328441 Roasting coffee grain &c SMITHERM INDUSTRIES Inc 13 May 1971 [8 June 1970 26 April 1971] 14818/71 Heading A2Q Heat processing of particulate solids, e.g. the roasting of coffee, cocoa beans or nuts, or production of expanded food products such as puffed cereals or popcorn, or drying of cereal grain, is performed in a reaction vessel 22 to which the solids are fed through an inlet 50 to form vertically extending, upwardly diverging beds 62 between vertical paddles 96 which radiate from a rotor 92 operated continuously or stepwise by an electric motor 136, the lower portions of the paddles being shaped to correspond with fixed annular walls 70, 82, 72 and openings 88, 89 being provided in the walls 82, 72 respectively, to admit heated inert gas, e.g. pressurized nitrogen, to fluidize the beds so that the solids are circulated in the manner indicated by arrows 90 and roasted as each bed passes between the feed station and a discharge station at which the solids fall through a hole in the bottom wall 82 communicating with a discharge conduit 52. As shown, the supply and withdrawal of solids are effected by rotary feeders 26, 36, the pockets 48 of which are evacuated by conduits 51a, 51b. Inert gas withdrawn by the conduits 51 b is returned to the system. In a modification, in which the rotor turns stepwise under the control of a timing shaft, the rotary feeders are replaced by air lock chambers controlled by a system of solenoid-operated valves also governed by the timing shaft. The roasting gas, circulated in a closed system which includes a heater, a condenser for removing moisture from the gas, and a chaff separator, is admitted to the vessel 22 through a conduit 58 and discharged through a conduit 60. Roasted solids leaving the vessel pass through a cooler (not shown) e.g. of rotary drum type.

Title: Improvements in or relating to guards for power-presses and the like
IPC: F16P3/04
Filed: 1948-06-02
Abstract: 663,074. Machinery safety devices. PRESS GUARDS, Ltd., and EVANS, F. A. July 1, 1949 [June 2, 1948], No. 14857/48. Class 80 (iv) In a safety device for a press or like machine the last part of the closing movement of a manuallyoperated guard is adapted to trip or release a weighted or spring-loaded member, which has been energised by a moving part of the press during the previous stroke, to engage the machine clutch. As shown, a spring 62 is adapted to be compressed by a cam 76 on the machine crankshaft 77 acting through a lever 73 and rod 72 on a collar 59 during the working stroke of the machine. The collar 59 is then engaged by a catch 57 to retain the spring 62 in a compressed state until the next operation of the machine is initiated by depression of a pedal 40, which first closes the guard (not shown) through a leakage 44, 45, 48, 49, and then operates a trip member 53 through linkage 50, 50<SP>1</SP>, 51 to release the catch 57 and allow the spring 62 to actuate a clutch extractor 69 through linkage 64, 65, 67 to start the machine. To obviate a repeat stroke of the machine should the pedal 40 be held down and maintain the catch 57 disengaged by the trip 53, a plunger 78 on the rod 72 is adapted to move the trip 53 downwards to free the catch 57 and allow it to engage and hold the collar 59 and the extractor 69 in its clutch disengaging position. An interlock between the guard and the clutch extractor 69 as described in Specification 663,077 may also be provided.

Title: Transistor oscillators
Inventor: FREEMAN JOHN WILLIAM HERBERT
IPC: H03B5/12
Filed: 1961-04-25
Abstract: 930,595. Transistor oscillator circuits. JOSEPH LUCAS (INDUSTRIES) Ltd. March 21, 1962 [April 25, 1961], No. 14869/61. Class 40 (6). An oscillator comprises a capacitor 5 connected across a source of supply, a transistor 6 having its collector electrode connected to a first terminal of the source, its emitter electrode connected through a first relay core 7 to the second terminal of the source and its base electrode connected to the first and second terminals of the source through a resistor 8 and a capacitor 9 respectively, and a second relay coil 12 connected in series with a normally open relay contact 13 across the terminals of the source, both relay coils acting when energized to close the contact 13 and the closure of said contact serving to initiate discharge of capacitor 9. The circuit may supply pulses for lighting a neon lamp connected across the secondary winding 15 of a transformer 11. A diode 16 may be connected as shown between the junction of winding 12 and contact 13 and the base of transistor 6; preferably, however, source 4 has a high resistance in which case the diode connection is omitted. With a high-resistance source 4 capacitor 9 charges until sufficient current flows through relay winding 7 to cause contact 13 to close. This completes the circuit through winding 12, thus making the closing of contact 13 more positive. However, since windings 10 and 12 are of low resistance, the potential at the collector of transistor 6 falls and capacitor 9 discharges through the base-collector diode until insufficient current flows through winding 7 to maintain contact 13 closed, whereupon the cycle repeats. If, however, source 4 has a low resistance, the potential at the collector of transistor 6 will not fall sufficiently when contact 13 closes to discharge capacitor 9. In this case diode 16 is provided through which capacitor 9 discharges when contact 13 closes.

Abstract: 791,048. Vehicle power steering. GENERAL MOTORS CORPORATION. May 14, 1956 [June 2, 1955], No. 14903/56. Class 79(5) In a fluid pressure, motor vehicle power steering mechanism having a piston 116 connectible to the vehicle frame 10 and contained in a cylinder 64 rigidly connected to a ported casing 60 of a control valve, a rocker arm 24 and an idler arm 18 are connected respectively to a valve spool 35 and the ported casing 60, the idler arm 18 being pivoted about the axis of a shaft 17 carrying the rocker arm 24 and being connected to a steering linkage part 20, the rocker arm 24 being located adjacent the idler arm 18 and the connection (shown as a bolt 19) between the rocker arm 24 and spool 35 passing through an aperture 30 in the idler arm 18. As shown a boss 36 on the upper end of the arm 24 carries by means of a bearing 38 the arm 18 having at its lower end 18a a ball and socket connection to the steering linkage part 20. Adjacent the aperture 30 the arm 18 carries by means of a boss 33 and a bearing 32 a casing 28 housing a shaft 46 through which the bolt 19 extends without play. The casing 28 is secured to the valve casing 60 and the shaft 46 is connected to the valve spool 35 which is centred in the casing 60 by a spring 128. The'casing 60 is connected to an end cap of the cylinder 64 comprising a pair of concentric members 104, 106 and an end cap 112 through which passes a rod 114 carrying the piston 116 dividing the cylinder into spaces 92, 94, the rod 114 being resiliently connected to the vehicle frame. In operation, manual operation of the steering gear 12 rocks the shaft 17 to cause relative movement of the arms 18, 24 as governed by the clearance in the aperture 30 and the spring 128. Such relative movement causes relative movement between the spool 35 and casing 60 whereby one of the spaces 92, 94 is pressurized from an engine driven pump 84 and the other space is connected to a reservoir 86. Such pressurizing causes power movement of the arm 18 which is connected to the steering linkage. The spring 128 is stated to give the driver "feel". Specification 750,589 [Group XXIX] is referred to.
