Title: Improvements in or relating to the tuning of electrical circuits
Inventor: GRIFFIN LAURENCE JAMES
IPC: H03J1/04
Filed: 1952-12-17
Abstract: 713,310. Adjusting radio apparatus. KOLSTER-BRANDES, Ltd. Dec. 17, 1952, No. 31953/52. Class 40 (5) The shaft 4, Fig. 1, of the tuning condenser of a radio receiver is driven by an arm 1 moving over a scale 7 and also serving as a pointer; a rotatable rubber wheel 2 is mounted on the end of the arm 1 and is maintained pressed firmly against the scale 7 by the action of a spring 3. The scale 7 may be illuminated from behind and the pointer is a part-cylindrical transparent moulding acting as a lens magnifying the figures on the dial seen through the pointer. The moulding carries a line indicating the precise tuning. Tuning is effected by moving the pointer by hand, the final adjustment being made by rotating the wheel 2. In the modification shown in Fig. 3, light is "piped" along the transparent pointer from the lamp 9. The scale 7 may be either translucent or opaque.

Title: Expandable polymers of vinylidene aromatic compounds
IPC: C08J9/224
Filed: 1972-07-07
Abstract: 1407263 Coated particles SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 6 July 1973 [7 July 1972] 31965/72 Heading B2E [Also in Division C3] Coated expandable particles of a polymer of a vinyl or vinylidene aromatic compound are made by contacting expandable particles of the polymer with a glycerol ester of a C 10-30  ethylenically unsaturated fatty acid, e.g. a drying oil, and allowing or causing the coating to oxidise and thereby harden on the surface of the particles. The coating may consist of linseed oil having a catalyst which promotes its oxidation e.g. a paint drier. In the examples expandable polystyrene beads were coated with a solution of linseed oil in isopropyl alcohol and optionally containing cobalt naphthenate (paint drier), lauric diethanolamide (antistatic agent) and magnesium carbonate.
Patent GB-742040-A (GB)
Title: Removal of sulphur chloride from mixtures containing perchloromethyl mercaptan and sulphur chloride
Filed: 1953-11-18
Abstract: Sulphur chloride is removed from mixtures containing perchloromethyl mercaptan and sulphur chloride by treating with water and chlorine, or substances yielding chlorine, until the sulphur chloride is transformed into aqueous hydrochloric and sulphuric acids.  The mixture may be stirred in water, with cooling, while introducing chlorine so rapidly that no sulphur precipitates or alternatively the mixture may be stirred into ice and chlorine water.  Instead of elementary chlorine, a chlorate in acid solution or a hypochlorite may be used.  Crude perchloromethyl mercaptan may also be distilled in a stream of water vapour and chlorine preferably continuously.  In examples (1) a chlorination mixture consisting of carbon disulphide and chlorine is dropped into water whilst chlorine is introduced with cooling and stirring.  By separating and fractionating the light yellow oil, pure perchloromethyl mercaptan is obtained; (2) the chlorination mixture is dropped into a packed column while chlorine and water vapour are introduced below at such a rate that a clear, non-fuming condensate forms.  The light yellow oil separating from the aqueous phase in the condensate is rectified to give perchloromethyl mercaptan.

Title: Improvements in and relating to coin-testing devices
IPC: G07D5/04
Filed: 1933-11-17
Abstract: 423,271. Coin - freed apparatus. ELEKTROZEIT AKT.-GES., 136, Mainzerlandstrasse, Frankfort - on - Main, Germany. Nov. 17, 1933, No. 32120. Convention date, Nov. 17, 1932. [Class 27] Testing coins.-Coins pass down an inclined track 1, where they are tested for size, onto a weighing lever 2. A coin of correct weight just reaches a point 8 at which the lever is tilted, so that it is passed in the direction B to associated apparatus. Under-weight coins do not tilt the lever, and are removed by means such as a pivoted flap in a side wall of the track. In order to prevent the passing of a coin when a second coin is inserted with an under-weight coin still in the weighing lever, a buffer 6 and support 7 are provided, which co-operate with the end of the track 1 to support the coins in the positions 5<a> and 5b. Guide members making point or line contact support the coin laterally whilst being tested.

Title: Improvements relating to aerodynamic control spoilers for missiles
IPC: H03B5/12
Filed: 1962-08-22
Abstract: 951,031. Controlling guided missiles. L. BOLKOW, [trading as BOLKOW-ENTWICKLUNGEN KOMM.-GES.]. Aug. 22, 1962 [Aug. 22, 1961], No. 32221/62. Heading B7G. Apparatus for controlling the oscillation of an aerodynamic control spoiler for missiles comprises a coil connected with the spoiler and located in a magnetic field, the spoiler oscillating continuously in response to two direct current impulses arranged to flow alternately in different directions in the coil. The mechanism is shown installed in an aerodynamic surface 1 of a missile wherein a hot magnet 3 is attached to a spar by distance pieces 4, 5 and the spoiler 6, comprising two blades 7 and 8 connected at 9 and 10, is mounted in slits 11 and 12 in the surface for movement along the axis of the magnet, tees 14 connecting the spoiler with lugs 25 on distance piece 5 to prevent rotation of the spoiler about the axis of the magnet. The spoiler is apertured at 13 to accommodate the magnet which is formed with pairs of cooperating diametrically opposite slits 36 and 37 which permit full reciprocating movement of the spoiler. The magnet comprises a core 28 having a flange 29 and an internal casing 30 and an external casing 31. A winding 35 is carried by core 28 and a sleeve 77, formed with slits 40, 41 to engage the aperture in the spoiler, is mounted in the annular gap between casings 30 and 31. The magnet and spoiler are connected for relative axial movement by a plunger 19 secured to the spoiler and mounted within a bush 20 mounted in the core 28. A winding 17 on sleeve 77 is energized by a continuously reversing D.C. current, whereby the sleeve and the associated spoiler reciprocate continuously along the axis of the magnet. To achieve this, the output of a generator (not shown) is applied to the terminals 71, 72 of a relay 70, the armature 73 of which operates reversing contacts 74 and 75. These are connected to the bases 58 and 62 of two power transistors 59 and 63 and the collector 56 of one transistor 59 is connected to the emitter 60, the other transistor 63 and to one end 51 of winding 17 of which the other end is connected to interconnected opposite poles 52 and 53 of two D.C. sources 54 and 55. The positive pole 64 of source 54 is connected to the emitter 57 of transistor 59 while the negative pole 65 of source 55 is connected with the collector 61 of transistor 63. A current supplied to the bases of the transistors to cause them alternately to block and conduct is derived through reversing switches 74, 75 from voltage dividers 68, 69 so that the apparatus forms two circuits which supply current alternatively in opposite directions through winding 17.

Abstract: 489,325. Valve generating circuits ; thermionic distributers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 25, 1937, No. 32504. Convention date, Dec. 1, 1936. [Class 40 (v)] A generator for producing short timed pulses comprises a valve the grid bias of which is controlled by an alternating source so that the valve is rendered conductive at intervals and additional means are provided to suppress the signal impulses periodically. The Figure shows a valve 20 in which the grid is normally biassed to zero but the bias is altered bv alternations fed through transformer 24 applied through the full wave rectifier 21, 22 and resistance 26. A condenser 31 is provided so that alternate pulses are insufficient to render the valve conductive so that the valve is rendered conductive once per cycle at the frequency applied to transformer 24. The invention is applicable to a signalling system as described in Specification 469,761 in which a plurality of different phases are derived from an alternating current and applied to a number of generators to give a series of voltage peaks at accurately timed intervals.
