Title: Improvements in and relating to electronic heating devices
Inventor: SMITH PETER HAROLD
IPC: H05B6/80
Filed: 1965-04-08
Abstract: 1,092,484. Microwave heating. MICROTHERM Ltd. April 7, 1966 [April 8, 1965], No. 14913/65. Heading H5H. A comestible to be heated by microwaves is rotated about an axis and reciprocated along the same axis whilst subject to the microwave field. As exemplified, a comestible 2 is supported within an oven 1 upon a turn-table 3, having a vertical shaft 9 of dielectric material which passes through a metal bush 10 in the floor of the oven. The shaft and the bush together form a cylindrical waveguide dimensioned beyond cut-off for the operating frequency of the oven. The shaft is coupled by sliding splines 12 to a rotating gear train 11, 14, driven by a motor M1. The splines allow the shaft to be reciprocated by a cam 18, driven by a further motor M2. The use of two motors ensures that the frequencies of the two motions will not be in a simple ratio to each other whereby even heating of the comestible is ensured. Both motions may be derived from the same motor, one directly, and the other through a continuously variable speed-change coupling. This may consist of two coaxial parallel discs coupled by a ball, the distance of which from the axis varies in a controlled or random fashion.

Patent GB-398960-A (GB)
Title: Improvements in or relating to apparatus for governing steam turbines
IPC: F01D1/02
Filed: 1932-05-27
Abstract: 398,960. Motor power plant; speed governors. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and PREISIG, P., 12, Danson Mead, Welling, Kent. May 27, 1932, No. 15096. [Classes 57 and 110 (iii).] In motor power plant, particularly for ship propulsion, in which a reciprocating engine exhausts into a turbine, the turbine driving a generator which feeds a motor on the shaft of the reciprocator, the turbine is governed so that its speed is maintained in a definite relation to the speed of the main reciprocator shaft. This is effected by varying the exhaust pressure of the reciprocator, that is, by varying the inlet of the turbine thus transferring load from one power unit to another. The figure shows the turbine unit of the plant with its valve and governor gear. The turbine, which receives its supply through a plpe 7, has two stages 8a, 8b and is controlled by a bye pass valve 16 which is actuated by a servo-motor 15. The pilotvalve 14 of this motor is moved through the linkage 12 by a governor 26 driven from the turbine shaft. It is also under the influence of a governor 2 driven by the shaft 1 of reciprocator. This governor acts through a fluid relay 18 which varies the pressure in a chamber 21 containing a plate 22 bearing upon a spring 23. This spring acts upon a plate on the governor rod 20 and varies the setting of the governor. In a modification the centrifugal governor 26 is replaced by an oil pump driven by the turbine shaft. The oil, the pressure of which depends on the speed, actuates the bye pass valve through a servo-motor, and its pressure is influenced also by a leak-away valve controlled by the governor 2. At excessive speeds an emergency governor actuates a valve 41 to bye pass the steam from the pipe 7 to the condenser 9.

Title: Improvements in Lens Adjusting Devices for Photographic Cameras.
Inventor: GILL HUBERT ALEXANDER
IPC: G03B3/00
Filed: 1918-01-09
Abstract: 122,151. Gill, H. A., (International Patent Licensing Corporation). Jan. 9, 1918. Cameras, baseboard and like fittings for.-In a folding bellows camera, the lens slide 4 is provided with a pair of thumb-and-finger projections 2 and carries a spring-pressed pivoted plate 8 arranged to engage a stud 12 when the bellows are extended. The final adjustment of the lens for focusing purposes is obtained by sliding the stud 12 by means of a lever 13 carrying a pointer 20 moving over a curved scale 15 carried by a pivoted lever 16. Means are provided for locking the lever 13 in different positions on the scale 15. When the lens slide 4 is moved inwards by means of the projection 2 to collapse the bellows, the plate 8 is automatically tilted, thus disengaging the stud 12 from the slide 4; at the same time, the lever 13 is automatically moved slightly inwards by a spring 17, thus unlocking the lever 13 from the scale 15 and allowing a spring 25 to restore the lever 13 to the position shown in Fig. 1. Reference is made to Specification 122,018.
Patent GB-781180-A (GB)
Title: Improvements in apparatus for the feeding of powder and like fluent materials
Inventor: ROSE ALFRED GERMAN
IPC: B65B1/46
Filed: 1954-05-22
Abstract: 781,180. Photo-electric control. ROSE BROS. (GAINSBOROUGH), Ltd. May 13, 1955 [May 22, 1954; May 27, 1954], Nos. 15111/54 and 15662/54. Class 40 (3). [Also in Groups XVII, XXXV and XXXVIII] In a carton filling machine (see Group XXXV) of the type in which telescopic hoppers feeding the cartons have their capacity adjustable as a result of check weighing in order to keep a constant weight of carton charge, a follow-up device incorporated in the check weigher permits a capacity adjustment proportional to the weight deviation of the test charge. A detecting arm 118, Fig. 3, moves with the weigh-beam 104 of the check weigher, so that weight deviations of the test charge supplied to the weigh-pan 114 results in a screen 139 carried on arm 18 cutting- 'off the light to one or other of a pair of photocells 141. A reversible motor (not shown) is thereby energized to correctively adjust the capacity of the hoppers and to rotate a shaft 99, thereby moving a sleeve 154 which, through a link 148, causes rotation of a follow up arm 147 relative to a shaft 144, Fig. 4, on which the arm is mounted. An arm 143 carrying the photocells is mounted for rotation with shaft 144, the movement of arm 147 being communicated to arm 118 by means of a spring 152 and a thrust nut 153 on the shaft which urge the arm 147 against a friction disc 149 between the two arms. The capacity-adjusting motor is thus energized until correspondence between the detector arm 118 and the arm 143 carrying the photo-cells is re-established, the amount of adjustment being thus proportional to the weight deviation of the test charge. When the detector arm returns to its vertical position, a cam-operated switch (not shown) prevents operation of the photo-cells. The arm 143 is returned to the vertical by a cam-operated resetting blade 158 which coacts with rollers 151 on a doublearmed lever 151 centrally mounted on the shaft 144, so that the latter is rotated against the action of the friction disc 149.

Title: Improvements in change box motions for looms for weaving
IPC: D03C1/36
Filed: 1935-05-24
Abstract: 434,347. Loom change-box motions. HEYWORTH, E., 99, Park Drive, Alkincoats Road, Colne, Lancashire. May 24, 1935, No. 15114. [Class 142 (iii)] Relates to change-box motions in which the operation of the eccentrics for determining the positions of the shuttle-boxes is controlled by levers 1, 2, Figs. 2 and 3, under control of dobby, jacquard, or pattern barrel mechanism. In order that a particular pattern indication may always produce the same shuttle - box position irrespective of a previous position, the levers 1, 2 carry, at right-angles to their common axis 14, selector levers 7, 11, normally assuming the positions shown in full lines in Fig. 3 but capable of being moved outwardly against stops by levers 42, 45 operated by cams fast with the respective box eccentrics 3, 4. The selector levers have pins 21, 22 adapted to be engaged by the pattern barrel, or, as shown by tumbler levers 26 .. 29 carried by a swing arm 24 on an oscillating arm and connected by wires 30 to swing beams 31 of jacquard or dobby transmission levers 35. Each tumbler lever is connected by the wires to two swing beams, while each beam is connected with two tumbler levers. The wires have looped connections with the tumblers so that each tumbler may be lifted independently by either of the two beams to which it is connected. After each operation of an eccentric, the corresponding selector lever is moved either to its inner or outer position to be engaged, or not, by a tumbler lever at the next operation.

Abstract: 221,284. Packer's Supply Co., Ltd., and Trouton, M. June 9, 1923. Sealing.-Relates to the securing means in an apparatus for straining and securing metallic straps around bales &c., in which the initial rotation of a lever and associated parts tensions and cuts the strap, the ends of which are clamped and are caused to approach one another in a converging path other than a straight line, further rotation of the lever members in the same direction sealing the strap. Downward movement of the lever-handle l from the position shown in Fig. 2 depresses a sliding block 26 to actuate clamping- jaws 21 through links 22, 23 to seal the ends of the strap by wrapping a sealing-strip there around, and by deforming the strap and sealing- strip, the action being generally similar to that described in Specification 189,942.

Title: High density electronic packaging
IPC: H05K7/00
Filed: 1959-05-04
Abstract: 868,877. Circuit assemblies. FRANCIS, S. A., and GRAY, P. J. May 4, 1959 [May 20, 1958], No. 15228/59. Class 37. A self-supporting electronic circuit assembly is made by welding the component leads to conductors which form the only electrical connections and support means. As described a number of transistor amplifiers (Fig. 1, not shown) are formed into an encapsulated unit and a number of such units assembled into a complete assembly, Fig. 8. A number of pairs of transistors 10, 10<SP>1</SP>, Fig. 5, are stuck back-toback and have their electrodes connected by welding to soft stainless steel wires, for example 30. The associated circuit components are formed into two further assemblies (Figs. 6, 7, not shown) and the three assemblies are joined by welding the connecting points to form an unitary self-supporting structure, any unwanted wiring connections being subsequently removed by cutting, Fig. 4. The assembly is encapsulated into a block 62, Fig. 2, into which a number of transverse tubes 64 are inserted, the wiring connections being terminated in connectors 50. A number of such blocks may be formed into a complete unit, Fig. 8, by passing wires 68 through the tube 64, and wires 66 through similar tubes vertically inserted in the blocks. The wires are then tightened by screws 70 to hold the blocks together. In order to improve cooling the column of blocks may be interleaved with conductive foils connected to a heat sink plate fixed to the base of the unit (Fig. 9, not shown). Alternatively several blocks may be assembled side-by-side to form a flat wafer, with interconnecting wires running in two directions to terminals on all four sides of the assembly (Fig. 10, not shown).

Title: Improvements in or relating to electrical oscillation generators
IPC: H03C3/32
Filed: 1946-05-20
Abstract: 646,009. Magnetrons. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 20, 1946, No. 15262. Convention date, Nov. 16, 1944. [Class 39 (i)] Variable-frequency high-frequency apparatus comprises a cavity resonator 11, Fig. I, situated in a magnetostatic field H whose magnetic lines of force extend through the resonator in one direction, auxiliary means (such as a cavity magnetron 27) for exciting the resonator to produce a high-frequency electric field E extending in planes normal to H, means (such as cathode 14) for directing a beam of electrons into and through the resonator in a direction substantially parallel to H, and means for variably controlling the transit time or intensity of the beam. It is shown that, if the frequency is in the region of the Larmor frequency eH/m, a very small change of transit time (by a signal from transformer 25 which varies the beam accelerating voltage) will introduce a reactive impedance into the resonator 11, either capacitative or inductive, and this will result in a change in frequency of the magnetron 27. A change in beam density (by a signal from transformer 20 applied to control grid 15) will produce a similar effect by altering the value of the reactive impedance. Electrode 16 may collect the beam or reflect it back to the resonator 11. In a modification, the beam is introduced into one or more of the cavity resonators of the magnetron itself, by means of auxiliary cathodes 66, Fig. 9, the magnetic field used being the main field between magnetic inserts 34, 35. Insert 34 carries the main cathode and insert 35 the auxiliary cathodes, both being supported from the anode block 30 by spacers 36, 37, 40, 41. Control grids 66<SP>1</SP> are situated in front of each cathode 66. Collectors 67 are supported direct from the header 45. An annular auxiliary cathode and control grid could be used.

Title: Improvements in and relating to methods and apparatus for introducing lubricant into powdered materials
IPC: B22F1/10
Filed: 1950-06-19
Abstract: 683,037. Mixing appliances. BRITISH THOMSON-HOUSTON CO., Ltd. June 19, 1950 [June 29, 1949], No. 15272/50. Class 86 A method of introducing a lubricant into a powdered material consists in interfusing a stream of fine particles of the lubricant with a stream of the powdered material, the stream of lubricant being formed with the aid of an inert pressure gas which also serves to maintain a protective atmosphere at the point where the two streams interfuse with each other. The invention more particularly relates to the introduction of a pressing lubricant into refractory carbide metal powders. As described a stream of pre-mixed carbide powdered ingredients from a barrel 1 is delivered by a vibrating hopper 3 and vibrating shoot 4 into a mixing chamber 7. The lubricant is maintained at or above its melting point in a heated container 8, and carbon dioxide at a pressure of one-half to three pounds per square inch is introduced into the container 8 through the line 13 to force the melted lubricant along a heated pipe 11 to a spray nozzle 12. Carbon dioxide under pressure of twenty to fifty pounds per square inch is supplied to the nozzle 12 through line 15 to produce an atomized spray of fine particles of lubricant which is sprayed on to the stream of powdered ingredients. The carbide powder having lubricant sprayed thereon immediately falls into a hammer mill 22 for intimate mixing of the lubricant with the powdered ingredients, the resultant mixture subsequently falling into a receiving barrel 23. In order to synchronize the initial flow of both powder and lubricant a vane 18, displaceable by powder flowing from the shoot 4, is arranged to operate a mercury switch in the circuit of a solenoid valve 17 in the pipe 11. In order to maintain a closed system in which the powdered carbide mixture and the lubricant are housed and maintained in an inert carbon dioxide atmosphere, the barrel 1 is connected to hopper 3 by a rubber bellows 26 and the hammer mill 22 is connected to the receiving barrel 23 by rubber bellows 27. The proportions of the mixture are controllable by valves 14 and 16 in the carbon dioxide supply lines and by a rheostat 6 in the circuit of the vibrating mechanism of the shoot 4, the rates of feed by weight being indicated by means of scales 10 and 25 which carry the containers 8 and 23 respectively.

Title: Improvements in or relating to water ring primer pumps
IPC: F04C19/00
Filed: 1956-05-16
Abstract: 844,055. Liquid-ring pumps. HAMWORTHY ENGINEERING Ltd., and POLLAK, F. May 16, 1957 [May 16, 1956], No. 15274/56. Class 110 (1). In a water-ring priming pump, one or more openings are provided on the suction side of the water-ring chamber at the position where the pressure is between atmospheric pressure and the maximum pressure provided by the pump, whereby the pump may be automatically unloaded by varying the pressure at the suction opening. In the water-ring pump shown, the double-lobe casing 12 is of elliptical shape, and a suction opening 15 and discharge openings 16 are provided. The pump is unloaded by discharging the water ring through openings 17, and loaded by the return of water through the openings 17. For this purpose, the pressure at the suction opening 15 is varied to produce a corresponding variation in the pressure at the openings 17, whereby, if there is air pressure at the suction opening 15, water flows outwardly through the openings 17, whereas if there is a vacuum at the suction opening 15, water flows inwardly through the openings 17. The necessary variation of pressure at the suction opening 15 may be effected by means of a float gear connected to the suction side of the centrifugal pump being primed and operating a pair of valves whereby, when the float is in one position, the suction opening 15 is connected to atmosphere so that the pressure thereat is high, and when the float is in the other position the suction opening 15 is subjected to the vacuum produced at the suction side of the centrifugal pump.
