Title: Improvements in and relating to electric discharge devices
IPC: H01J61/10
Filed: 1937-03-19
Abstract: 495,870. Discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., and GABOR, D. March 19, 1937, No. 8169. Addition to 442,307. Drawings to Specification. [Class 39 (i)] A discharge device with an inner discharge space containing a source of slow electrons such as a hot, preferably indirectly heated, cathode, which communicates with an outer discharge space only through openings in an insulated " plasma-filter " is controlled by a magnetic field having a component parallel to the cathode surface. The device is preferably one having a " dark discharge " in the inner space as described in Specification 455,967. Fields of the order of 10-20 gauss produce marked reductions in the discharge current. The coil producing the magnetic field may be in series or in parallel with the device. Two coils producing opposed magnetic fields may be employed, one in series and one in parallel with the discharge ; or the latter may be provided with a constant biassing current. Curves showing the resultant characteristics for each of the above arrangements are given. The coils may have saturating iron cores or shunts. A further curve shows the dynamic characteristic of a device in parallel with a pure inductance. The artificial characteristics thus produced may have negative portions, when the device is suitable for oscillation generation ; other applications are to lamps and to current control. The filling may be neon at 0À4 mm. pressure.

Title: Improvements relating to electrical insulation
IPC: H01B3/18
Filed: 1937-03-22
Abstract: Electric insulating material for use in making electric cables, transformers, condensers, or the like comprises a sheet or band of a synthetic resin or a cellulose ester or ether free or substantially free from a tendency to shrink when heated.  Resins specified are polyvinyl chlorides, polyvinyl acetates, polystyrene, polymaleic acid derivatives, and mixed polymerizates.  Cellulose derivatives specified are ethers such as ethyl and benzyl cellulose, esters such as cellulose triacetate, acetone soluble acetate and cellulose propionate, and cellulose ether-esters.  The sheets may be produced (a) by maintaining a sheet formed in the usual manner at a temperature above its softening point but below its melting point whilst it is relieved from tension as far as possible until it is free or substantially free from shrinkage, e.g. by allowing it to hang freely or by supporting it on a yielding support such as a thin sheet of acetyl cellulose, (b) by slowly casting a solution of the cellulose derivative or resin on an elastic support such as glass coated with polymerized butyl acrylate, or (c) by heating the support, e.g. a drum, upon which the sheet is cast.

Title: Improvements in diaphragms for use in acoustic reproducing devices
IPC: H04R7/14
Filed: 1927-03-28
Abstract: 280,424. Menkens, C. March 28, 1927. Diaphragms; loud-speakers; magnetic instruments.-A conical diaphragm 1 for sound reproducing instruments, such as loud-speakers, is formed with apertures 2 and radial and concentric strengthening ribs 3, 4. The ribs 3 instead of being radial may be arranged in a spiral or other desired form. The diaphragm is formed from thin sheet material, such as aluminium, wood, celluloid, papier-machÚ or cardboard, the cone being covered on one or both sides with thin paper, silk, &c. and subsequently treated with a suitable dope. The diaphragm may be formed by spinning, moulding, or, as shown in Figs. 4 and 5, by first cutting out a flat disc which is pressed by suitable dies into a cone shape, the surplus metal being taken up by folding the sheet on itself on lines radiating from the centre so as to form the radial ribs 7. The periphery of the cone may be of channel formation as at 5, Fig. 2, or may be wrapped round a fine wire or cane 6, Fig. 4. Numerous methods of flexibly mounting the periphery of the diaphragm on a baffle ring 9 in a casing 10, Fig. 6, are described, the apex of the cone being directed either towaards or away from the back of the cabinet, an additional member being, in some cases, secured to the inner edge of the ring 9. In the construction, Fig. 2, a number of radial strips 8 are formed from or attached to the periphery of the cone, the outer ends of the strips being secured as shown to the ring 9. In a modification, the strips 8 are replaced by coiled spring wire members. Fig. 6 shows a construction in which the periphery of the diaphragm is attached to a continuous strip of tape 13 secured to the ring 9. In other constructions, the periphery of the cone is mounted either on the inner edge of the ring 9 or on the additional member secured thereto by means of a flat or frustum-shaped continuous strip of flexible material. In constructions in which the ribs 3 extend to the apex of the cone, similarly ribbed washers 30, 31, Fig. 4, are provided so as to obtain a firm connection between the apex of the cone and its actuating armature. In other constructions, the apex of the cone is flattened or otherwise suitably shaped, various forms of washers being described adapted to co-operate therewith. According to the Provisional Specification the periphery of the diaphragm may be left free.

Title: Improvements relating to electronic trigger circuits
Inventor: DRAKE BERNARD
IPC: H03K3/2893
Filed: 1960-03-11
Abstract: 896,463. Transistor switching circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 8, 1961 [March 11, 1960], No. 8729/60. Class 40(6). An electronic trigger circuit having a resistance capacitance timing network for providing a delayed trigger input to the circuit has the triggering input taken from a point on the resistive portion of the network such that transients arising in the supply connection are neutralised as regards their effect on the trigger circuit. The Figure shows a transistor trigger circuit comprising cross coupled transistors T1, T2 which, when switches Sl and S2 are closed, is in a condition in which transistor T2 is fully conducting and T1 cut off, so that a relay B is operated. Opening switch S2 permits a capacitor C to charge and when the voltage across it has reached a certain level transistor Tl will become conducting and T2 will be cut off and relay B will be released. The base of transistor T1 is connected to a tapping on the charging resistance Ra, Rb such that the ratio of Rb to Ra is equal to the ratio of R1 to R2 and R3 in parallel so that, for example, when the circuit has just been triggered and relay B has not yet released, surges on the line will not return the circuit to its original condition and so cause the capacitor to discharge through the base emitter circuit of transistor T1 and re-initiate the charging cycle. Transistor T2 is biased by the forward drop across a rectifier rfl, though the rectifier could be replaced by a resistor. It is stated that the circuit could be modified so that the trigger circuit carries only sufficient current to hold the relay operated after it has been operated by an independent circuit or so that the initial trigger current acts in opposition to an operating current and so holds the relay initially released.
