Title: Improvements in and relating to the control of alternating current circuits by saturable chokes
IPC: H01F29/14
Filed: 1936-09-15
Abstract: 467,628. Supply systems for consumption apparatus; inductances; dynamoelectric machines. PINTSCH AKT.-GES., J. Sept. 15, 1936, Nos. 25154 and 25155. Convention dates, Sept. 21, 1935 and Oct. 10, 1935. [Classes 35, 38 (ii), and 38 (iv)] The flow of A.C. in one or more electric circuits is started and stopped by variations of inductance in saturable core choking coils in the circuits, the cores being saturated to render them conductive by a magnetic biassing flux obtained from permanent magnets or electromagnets which are moved into and out of their biassing positions. The biassing effects may be applied or removed in such a manner that no secondary effects are produced in the A.C. windings. The system may be used in the control of all kinds of electric apparatus or in the operation of electric machines such as in connection with commutation of electric generator or motors. In the arrangement shown in Fig. 1, lamps 2 are supplied from A.C. mains 3 through chokes 1, the inductance of which is such that very little current normally flows. The cores may be saturated in succession, to render the current conductive, by magnets 8, 81 movable along the row of chokes. To prevent secondary effects in the choke coils when the magnetic biassing effects are applied or removed, the portion 1<1> of the iron core, Fig. 2, is so arranged that the lines of magnetic flux pass on either side of it. The magnets 8, 8<1> are then movable in a direction which is perpen - dicular to the plane of the iron core. In the modification shown in Fig. 3, a number of connections 13 to consuming devices are each supplied through chokes arranged in a circle, each choke having a core formed as part of a common iron element. A saturating magnetic bias is applied to any one of the chokes by a magnet 8, rotatable about the centre and co-operating with the central magnet 8<1>. The method may be applied to the commutators of dynamo-electric machines, as shown in Fig. 5, the brushes being replaced by pairs of magnets 8, 8<1>, 9 9<1>, 10, 101, and 11, 11<1> co-operating with chokes 1 which replace the commutator segments to which the armature windings are connected. In a modification applied to a repulsion motor, chokes arranged diametrically opposite and connected in series are rendered conductive in pairs.

Filed: 1944-12-15
Abstract: 587,213. Scaling ladders. KAY BROS., Ltd., SINCLAIR, A. L., and HARTLEY, H. K. Dec. 15, 1944, Nos. 25260/44 and 1975/45. [Class 20 (ii)] [Also in Groups XXI, XXV and XXVIII] A suction device for securing articles to surfaces, particularly applied to adhering bombs but stated to be applicable to securing scaling ladders to walls, comprises an open-mouthed container provided at the mouth with a gasket for making joint with the surface, and containing an evacuated vessel which can be punctured to create a partial vacuum in the container. Fig. 1 shows a bomb comprising a container 1 having secured thereto at its closed end 2 a member 3 leaving a space 4 which can be packed with explosive (not shown). The mouth of the container carries a gasket 5 of channel section filled with sponge rubber impregnated with adhesive sealing compound. The container houses an evacuated vessel 8 of metal, glass, or other material which can be punctured at will. After applying the gasket to the surface, the vessel 8 is punctured by driving inwards a slidable headed pin 9 having a pointed inner end 10 passing through an aperture 11 in the container. The pin is slidably guided in a tubulure 13 secured to the container and is held outwards by a spring in compression between.the wall of the container and a flange 14 on the pin, the flange serving to seal the aperture 15 through which the pin stem slides. Fig. 4 shows an alternative puncturing device in which the pin is carried by a flexible diaphragm 18 serving to prevent leakage after puncturing has been effected. The pin may be held in its outer position by a lock pin 20 removable when required. The casing 16 is threaded at 17 to screw into the container wall. In another form of puncturing device the pin is carried by the inner surface of a thin metal dish soldered at its edges to the wall of the container, concave side outwards, with the pin registering with an aperture in the container. Puncturing is effected by buckling the dished member inwards. In a further arrangement a putty-like sealing compound is provided between two annular concentric shoes, one inside and one outside the mouth of the container, the mouth portion of the container being slidable between the shoes as an annular piston. In this case the shoes are applied to the surface and pressure is applied to the container to slide it towards the surface, this movement forcing the sealing compound into close contact with the surface. Further movement of the container effects puncture of the evacuated vessel by inwardly directed oblique pointed members (one shown in Fig. 3) carried by the inner shoe. The evacuated vessel, instead of being separate, may be a chamber having walls integral with those of the container. In all cases a protective cover may be provided over the gasket, removed when the device is to be used.

Abstract: 765,071. Testing coins electcically. YELLAND, L. J. Oct. 15, 1952 [Nov. 2, 1951], No. 25833/52. Class 37. [Also in Group XVIII] Testing coins : electric and magnetic properties.-The unbalanced voltage from an inductive bridge, whose balance is affected by the presence of a coin to be tested, is applied to a detector whose output depends on the phase of the unbalanced voltage relative to the input to the bridge as well as on its magnitude. This is stated to permit adjustment to pass valid coins of two different mints. The coin 16 (Fig. 3) to be tested, and a standard coin 15, are supported in similar gaps 12, 11 in the laminated core 9, 14 of a transformer, the primary 17 of which is connected to the A.C. mains. The secondaries 18, 19 of the transformer are connected in series-opposition and coupled by a condenser 79 (Fig. 2) to the grid 76 of a valve 75 the anode 74 of which is direct-coupled to a triode 64. When an invalid coin is under test the out-ofbalance voltage from secondaries 18, 19 raises the anode potential of valve 75 sufficiently to cause the current drawn by the anode of triode 64 to operate a relay 66 which prevents actuation of a vending machine. A condenser 81 connected across the secondaries 18, 19 may be adjusted so that, when a valid coin of higher conductivity than the standard coin 15 is under test, the ripple on the grid 76 is in phase with the voltage on the anode 74 and maintains the current drawn by the anode 74 sufficiently high to prevent operation of the solenoid 66.

Abstract: 833,886. T.R. switches. BRITISH THOMSON-HOUSTON CO. Ltd. Aug. 15, 1958 [Aug. 16, 1957], No. 25936/57. Class 39(1). [Also in Group XXXVI] A process for forming over a slot 2 in a metal wall 1 a window of vitreous material hermetically sealed to the rim of the slot and a protective dome over the window, for use in a T.R. device, consists in assembling the metal wall 1 with a length of glass tubing 4 located with its longitudinal axis parallel to the longitudinal axis of the slot and then heating the wall to cause the portion of the glass tubing in contact with the wall to soften and sink on and seal to the metal wall around the rim of the slot, whilst leaving the remainder of the tubing to constitute the dome. The heating may be effected by high frequency induction in an atmosphere of non-oxidizing or reducing gas or gases. With a narrow slot (about # in and under) the plastic glass is supported in the slot by its own surface tension. With wide slots (say “ in. or more) it may be necessary to support the centre of the glass pane e.g. by providing a gas pressure differential on opposite sides of the pane. The ends of the glass tubing 4 may be sealed to form an enclosure which is filled with gas and/or water vapour through an evacuating tubulation. Alternatively the ends of the tubing may be tapered to openings which may be made to an exact size e.g. by sealing in short lengths of vitreous or ceramic tubing.

Abstract: 1457105 Cathode-ray tubes ENGLISH ELECTRIC VALVE CO Ltd 28 Feb 1974 [1 June 1973] 26164/73 Heading HID An electron gun, e.g. for a storage tube or a pyroelectric vidicon, comprises a semiconductor cold cathode having a first diode 6 providing a finely focused electron beam and a further diode arrangement such as diodes 8 disposed symmetrically around the first diode at a constant radial distance therefrom and providing a relatively high current electron beam, the first and further diodes being independently energizable through respective metallic layers 7, 9. In a storage tube the fine electron beam is used for reading or writing and the high current beam for erasure or flooding the target. In a vidicon the high current beam is used to ionize residual gas with the further diodes held at a relatively positive potential to the first diode which is thus unimpeded in its normal operation and if the potential of the further diodes is arranged to be that of the image highlights at the target, then image spreading from the highlights is reduced.
