Title: Improvements in or relating to electric theft alarms
IPC: B60R25/10
Filed: 1945-02-27
Abstract: 597,041. Hand actuating devices for switches. BROWN, J. C., and BROWN, H. B. Feb. 27, 1945, No. 4892. [Class 38(v)] [Also in Group XXXVIII] In an electric theft-alarm system for vehicles a key-operated ignition switch is provided of the kind set forth in Specification 522,423 but of different construction. The switch has main contacts 13, Figs. 2 and 8, for preparing an alarm circuit, which is then completed upon movement of such parts of the vehicle or the like as may be desired, and auxiliary contacts 14 operated by a key with false wards to close the alarm circuit. Each main contact 13 is arranged adjacent an auxiliary contact 14 each being prevented from rotation by a projection 35, 37 engaging in a slot 36 in the switch casing 10, and each pair of contacts 13, 14 being separated by a spacer assembly consisting of discs 16, interlocking with each other and with the adjacent auxiliary contact, retained within an annulus 15. When a correct key 38 is inserted its wards retract spring-loaded slides 20, 20 mounted within a disc 18 of each main contact so that they are now clear of lugs 44 on a locking bar 39. When the key 38 is fully inserted its end pushes back a spring-loaded plate 43 which moves the locking bar 39 to the left, disengaging the lugs 44 from a notch 45 in each master contact 13 and engaging them instead in a semi-circular slot 19a which permits the key 38 to rotate master contact discs 18 through 180 degrees, in which position a contact strip 22 on each disc 18 bridges terminals 17, 17 to prepare the alarm circuit. When the key is now withdrawn the locking bar 39 returns to the right where each lug 44 engages a second, diametrically opposed, notch 45 in the contact discs 18, and the slides 20 move radially outwards to lock the bar 39 in this position. The switch can now be unlocked only by a key having the correct wards. Insertion of a false key will result in one or more of its wards engaging either an auxiliarly contact 14 or one or more of its interlocked spacer discs 16, Rotation of such a key in either direction will therefore turn an auxiliary contact disc and result in the terminals 27, 27 being bridged to close the alarm circuit, which is self-locking so that the alarm remains operated even if the key is withdrawn.

Abstract: 567,238. Gramophone pick-ups. PHILCO RADIO & TELEVISION CORPORATION. April 1, 1943, No. 5238. Convention date, April 2, 1942. [Class 40 (iv)] [Also in Group XL] In a pick-up of the condenser type, the metallic elements constituting the condenser are normally twisted about an axis, are torsionally flexed about this axis in use, and are constructed and arranged so as to compensate for the diminishing amplitude characteristic of records recorded at constant velocity. The condenser is formed of flexible strips 35, 36, 37 adapted to be torsionally flexed about their longitudinal axes by the stylus 41. The strips are tapered towards the stylus end, where they are embraced by a U-shaped clamp 39 on a short shaft carrying the stylus. A rubber bushing 42, around this shaft, and the fixed ends of the strips 35, 36, 37 are clamped between yoke pieces 44, 45. The middle strip 37, Fig. 7, is given a slight twist about its longitudinal axis before assembly of the strips, and the two outer strips 35, 36 are bent outwardly as indicated and may each have a rib 47, Fig. 5, extending longitudinally along the strip. The high-Frequency response may be limited by varying the effective length of the strips by adjusting the position of a small rigid plate 48 clamped with the strips. Fig. 3 shows a wireless receiver modified as in Specification 558,680, for use with the pick-up 33 which is connected by a constant capacity cable 34 to the tuned circuit 30, 31, 32 connected to the grid and anode of the oscillator section of the valve 23, which also acts as the local oscillator for wireless reception. The circuit 30, 31, 32 is tuned to a frequency above or below the intermediate frequency, so that the output of the I.F. amplifier 24 and the output voltage of the second detector will vary with the capacity of the pick-up 33.

Title: Improvements in or relating to the manufacture of rubber compositions
IPC: C08L7/00
Filed: 1931-02-20
Abstract: Granular precipitates capable of being consolidated by filtration are prepared from aqueous dispersions of rubber and the like by a modification of the process described in Specification 338,975, [Class 70, Indiarubber &c.], which comprises precipitating in situ in the presence of a relatively large quantity of water one or more compounding ingredients by the interaction of one or more water soluble reagents having normally no coagulating effects with other water soluble reagents an ion of which may incidentally possess coagulating influences, whereupon the granular precipitates are formed, which are sufficiently coarse to allow filtration, but sufficiently fine so that the film produced is indistinguishable from an ordinary latex film. Examples of water soluble reagents of the first class are carbonates, sulphates, silicates of the alkali metals or of ammonium.  Examples of reagents of the second class are soluble salts of magnesium, aluminium, calcium, barium or zinc, and in some cases sodium silicate, if the reagent of the first class is one which precipitates silicic acid.  The reagents may be chosen such that only one soluble reaction product and two insoluble products are formed e.g. sodium carbonate and magnesium sulphate followed by barium chloride.  The reagents are added in aqueous solution.  Protective colloids may be present.  The soluble salt is washed out from the granular precipitate.  The emulsions used are natural rubber and like latices, or artificial dispersions of coagulated rubber, vulcanized rubber, synthetic rubber, waste or reclaim.  Concentrates prepared as described in Specifications 219,635 and 290,313, [both in Class 70, Indiarubber &c.], may be used.  The products have properties ranging from those of soft rubber to vulcanite, and may be given a suitable form by filtration through a shaped porous former.  In certain cases vulcanization may be omitted.  Specification 350,450 is referred to.

Abstract: 1,255,894. Filter element. COMPTOIR DE LA FILTRATION COFI. 4 Feb., 1970 [4 Feb., 1969], No. 5369/70. Heading B1D. A filter element comprises a split tube 3 of resilient material with external channels and perforations 6, covered with a filtering bag 10 of polyamide or polypropylene fibres. During filtration (Fig. 4) the filtered solids build up and the rising differential pressure causes the tube to contract until its slit is closed, bag 10 still not touching the floors of the channels. When the downstream pump is shut off, the tube opens out again breaking the filter cake. The ends of tube 3 have a closure plug and connection sleeve (Fig. 2, not shown) to which the open end of bag 10 is secured by adhesive or a hose clip. Fig. 6 (not shown) illustrates a filter unit with several elements in one housing, filtering the water of a swimming pool, with an auxiliary circuit (18) for use in applying the filter aid, which initially lies in the lower part of the housing and may be used in several cycles before being discharged and replaced. The pump (14) and valve (15) may be actuated by differential pressure switches to clean the filter elements, apply filter aid and restore filtering flow at appropriate times.

Patent GB-806697-A (GB)
Title: Improvements in or relating to processes for fusing powdered semi-conductor materials
IPC: C30B11/10
Filed: 1955-02-24
Abstract: Semi-conductor crystals are produced by fusion and progressive re-crystallization of powder fed by means of a stream of gas or vapour to the surface of a melt of the semi-conductor material. Fig. 1 shows a silicon rod <PICT:0806697/III/1> <PICT:0806697/III/2> <PICT:0806697/III/3> 2 which is moved slowly upwards in a quartz vessel 1 so that molten silicon freezes from a depending bead 3 as it moves away from H.F. induction heater 4; the size of bead 3 is kept constant by supplying silicon powder in a stream of hydrogen through a lower extenson 5 of the vessel.  Fig. 2 shows the use of a number of helical baffles 11 between which hydrogen passes from an inlet 10 and which produce a turbulent whirling motion which lifts up silicon powder from a heap 9.  Instead of adding the powder to a molten zone at the end of a semi-conductor rod, such a rod may be thickened by depositing powder on to a molten zone on its cylindrical surface, or lengthened by depositing it on a central molten zone which is maintained at the same thickness by slowly pulling the ends of the rod apart.  In any of these processes the rod may be rotated during the operation.  In the embodiment of Fig. 4 a semi-conductor compound (e.g. boron nitride) in powder form is contained in a vessel 37 with a perforated base from which it falls into a stream of hydrogen from cleaners 33, 34 to be carried into a water-cooled vessel 41.  Here the boron nitride is atomized in the electric discharge between tungsten electrodes 41d and 41c, and is deposited on to a support 41f which is moved slowly downwards.  Conductivity-type-determining additives may also be conveyed by a gas stream for incorporation in the rod. The production of an indium antimonide rod is described.  In a modification of the above methods the semi-conductor material may be formed from a powder compound fed in a gas stream to the melt and decomposed by the heat of the molten zone or by an electric discharge.ALSO:Semiconductor crystals are produced by fusion and progressive re-crystallization of powder fed by means of a stream of gas or vapour to the surface of a melt of the semi-conductor material. In one example, powdered indium and powdered antimony are whirled in a stream of rare gas on to a molten zone on an indium antimonide carrier rod which is slowly withdrawn from a heating zone so that a crystallise length of indium antimonide is formed. In a modification indium hydride powder replaces the indium, and is decomposed by the heat from the molten bead.
