Abstract: 1,169,443. Automatic exchange systems. NIPPON ELECTRIC CO. Ltd. 22 Feb., 1967 [23 Feb., 1966], No. 8534/67. Heading H4K. A satellite communication system, in which the satellite has a transponder receiving in one frequency band F2 and retransmitting in a second frequency band F1, has earth stations which are each allocated exclusive use of some of the send channels, or some of the receive channels, or some of both. The invention is a recognition of the political difficulties that arise when one nation has exclusive control over all communication channels, as happens with a master station controlling the allocation of all channels. Earth stations originating calls agree with the wanted earth station which go and return channels from their common stock are to be employed. The channels are a frequency division multiplex of the bands F1 and F2; some of the channels being time division multiplexed. The channels are used for speech and telegraph signals.

Abstract: 595,086. Stoppers. RAY, F. F. April 7, 1945, No. 8631. [Class 125 (iii)] [Also in Group XXV] Means for hindering the unauthorised operation of devices having angularly movable members such as closure caps for motor vehicle petrol tanks or radiators or locking devices for electric lamp bulb sockets, comprising an actuating member retained to but freely rotatable about the angularly movable member to which it is adapted to be connected by a coupling member is characterised by the actuating member or a further member interposed between it and the angularly movable member being provided with at least one " through hole or slot through which the coupling member may be inserted to connect the actuating and angularly movable members and with a plurality of "blind" holes engageable by the coupling member but through which it cannot be so inserted. The outer cover 13 of a fuel tank cap, Fig. 1, may be formed with a depending skirt in which are formed one through hole 16 and a large number of blank holes 17. An inner angularly movable member 12 comprising a locking arm 14 adapted to engage the lip of the filler tube 11, a cover plate and a disc 18 having peripheral slots 19, pivots freely around the spindle 15. Each of the holes 16 and 17 is identified by a character formed on the cap 13 and the inner parts may be operatively engaged with the cap by inserting a pin through the hole 16 and engaging it with one of the slots 19. In modifications (1) several rows of holes may be formed in the skirt (2) all the holes may be through holes all but one being blanked off by an internal split ring having a detent engaged in one of the holes for locating it (3) the holes may be formed in a flange on the underside of the cap, for engagement by a hooked wire. In the form shown in Figs. 6 and 7, the cap is capable of limited axial movement against a spring 26 and carries a pin 28 for engaging holes 19 formed in the inner member through a hole 16 in a loose ring 27 which also has a number of blank holes 17. The hole 16 is engaged by turning the cap 13 until the detent 29 thereon engages the detent 27<1> on the ring 27 and then turning back through a known angle. A pointer 30 may be provided on the ring 27 to facilitate this. In the form shown in Fig. 8 a cut is made through the skirt in the plane of the centres of the holes 16, 17, the bottom part of the skirt being retained by a suitable flange. The two halves of the through hole 16 must-then be aligned before the pin can be inserted to engage the slot 19. Alternatively, a rotatable rim 13' may be formed around the edge of the cap 13 and having a through hole and blind holes, the through hole being brought into register with an inner one on the cap 13 before a pin can be inserted. The difficulty of finding the through holes by inspection may be increased by forming them at varying angles instead of radially.

Title: Improvements in or relating to the dividing of dough
IPC: A21C5/08
Filed: 1931-03-21
Abstract: 375,297. Dividing dough. WHITE, A. E., 5, Quality Court, Chancery Lane, London.-(Ward, Inc., A. F.; 2968, Jessamine Street, Cincinnati, Ohio, U.S.A.) March 21, 1931, No. 8786. [Class 87 (ii).] Lumps of dough 10 are placed in pans 4 and pushed intermittently through a machine, by hand, so that the dough in each pan is first flattened and greased by a reciprocating member 11, then distributed over the pan by plates 13 and divided by knives 14 after which the pans with the divided dough sheets are removed from the other side of the machine and conveyed to an oven. The oiling and flattening member comprises a vessel detachably connected to a member 73 which is guided in a tube 74 and forced downwardly therein by springs 79. The vessel has a fabric cover which is held in place by springs 72 and which dips into oil in the vessel, the oil being maintained fluid by an electric heater mounted in the base of the member 73 and supplied by a cable 82. The member 74 is carried by a head 44 which is guided on columns 8, 9 and is provided with knives 14 working between plates 13 mounted on pins 46 in a head 45, the latter being loosely guided on bushes 48 carried by the head 44. The columns 8, 9 are reciprocated by a crank mechanism driven through reduction gearing and an electric motor, the whole machine being mounted on wheels 20 to permit ready transport. The pans are pushed through the machine between adjustable side guides 3 and are located in turn below the dividing head by an adjustable detent 17, Fig. 5, which yields under sufficient pressure, to allow the pans to pass. The pan being properly positioned beneath the dividing head, the plates 13 and knives descend by gravity, the head 44 being carried by collars 50<a> on the columns, while the head 45 is supported by posts on the head 44. After the plates 13 have distributed the dough over the whole of the pan, a semicylindrical pawl 54 is tripped by a stop 57 and rotated into locking engagement with the column which thereupon moves the head 44 positively downwards to divide the dough. The knives contact with the bottom of the pan, but strain is prevented by forming the casing 19 which supports the table 2 of thin section so that it yields. If the pan is improperly positioned, the knives rest on the edge thereof and the locking pawls 54 are not engaged. The knives are surrounded by a guard 62 having horizontal portions 61 which strip the pan from the ascending knives and pressing plates. The pans may be strapped together in sets of three or may be fed individually.

Title: Improvements in or relating to electric semi-conductors
Inventor: MATTHEWS KENNETH ALBERT
IPC: H01L21/18
Filed: 1949-04-01
Abstract: 681,809. Semi-conductor amplifiers. STANDARD TELEPHONES & CABLES, Ltd. March 31, 1950 [April 1, 1949], No. 8902/49. Class 40 (iv). An electro-forming process for a crystal triode comprises the steps of passing a relatively small direct current between the emitter and collector electrodes, the base electrode being disconnected, and then momentarily increasing the direct current, such that after forming, the current voltage characteristic of the emittercollector path has no negative slope portion. The emitter electrode is polarized in such direction that it makes low resistance rectifier contact with the semi-conductor. Fig. 1 shows a suitable circuit in which the output from sawtooth generator 6 is applied across the emitter 4, collector 5 and resistances 7 and 8 connected in series. The deflecting plates of a cathoderay tube 10 are connected to display the emitter-collector current against the emittercollector voltage, and initially produce a curve such as the thick line of Fig. 2 which includes a negative resistance portion. A switch 9 which is connected across resistance 8 enables the current to be momentarily increased, and subsequently the loop portion of the curve is reduced so that the curve may take the form of the dotted line 15. This results in improved current amplification properties of the crystal triode. Pulses may be used in place of the sawtooth waveform. The voltage applied to the emitter should be positive in the case of N-type material. The collector electrode should include added material of donor type and may consist, for example, of phosphor bronze in the case of N- type material, or added acceptor type material in the case of P-type material. The collector electrode material should be softer than the semi-conductor material. The emitter and collector electrodes may be pointed or chiselshaped, and may contact opposite sides of a thin disc of semi-conductor instead of the flat surface as shown.

Title: An improved fluid pressure servo-motor for motorcars and the like
Filed: 1946-03-25
Abstract: 617,259. Controlling motor vehicles. MARTIN, J. March 25, 1946, Nos. 9074/46 and 4470/47. [Class 79 (v)] [Also in Group XXXIV] Control means for motor cars comprises a servomotor cylinder through which liquid is circulated and which may operate the clutch, valves controlling an outlet passage and connected to the brake pedal and the accelerator respectively and means whereby the controlling action of the accelerator-actuated valve may be made ineffective while the accelerator is not depressed. As shown, the cylinder A of a piston D connected by the lever C to the clutch of a motor vehicle is supplied through port G from a pump. Valves M, Q in an outlet passage P, P<SP>1</SP>, H are connected respectively by levers L, R to the brake pedal and accelerator so that with both of these in the raised position the valves are as shown and pressure builds up in the cylinder to move the piston outwardly against the pressure of a spring E to disengage the clutch, a relief passage I being then uncovered by the piston as shown. When the accelerator is depressed to increase the power supply, the valve P is opened, thus permitting the spring E to move the piston to the right to engage the clutch. Should the brake be applied at this time, the valve M is closed and the clutch is thus disengaged. To permit the clutch to remain engaged when the accelerator is not depressed as when running downhill against the engine, a third valve K may be provided which may be opened by a separate control to byepass the passage P, P<SP>1</SP>. The valve K is operated by a lever U having a toothed segment V meshed with a pinion W on the valve spindle and to prevent opening of the valve K when the accelerator is depressed a pin T is arranged to ride on to an abutment surface R<SP>1</SP> on the lever R of the valve Q. According to the first Provisional Specification, the servomotor is such as described in Specification 597,231, [Group XXXIV], and there is no mention of a valve corresponding to the valve K. The valve connected to the accelerator can in this case also be held open when required by an eccentric bush or link fitted to the control between the valve and accelerator and operable from the driver's position, but rendered inoperable when the accelerator pedal is depressed.
