Patent GB-450788-A (GB)
Title: Process for coating articles such as electrodes and other parts of electric discharge tubes
IPC: H01J19/00
Filed: 1935-06-11
Abstract: Electrodes and other parts of discharge tubes and other radiating bodies are blackened by electrophoretic deposition from a colloidal solution of graphite, active carbon or other substance or of a substance which may be rendered black by further treatment.  In an example tungsten oxide is deposited and is subsequently reduced in hydrogen to produce a black tungsten coating.

Title: Improvements relating to electronic pulse generating circuits
Inventor: DUNBAR COLIN ROBERT
IPC: F16D3/50
Filed: 1964-04-23
Abstract: 1,099,284. Pulse generating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 23, 1965 [April 23, 1964], No. 16856/64. Heading H3P. [Also in Division H2] In a pulse generator of the type in which a pulse forming network PFN is first charged from a power supply via an inductor and a diode and subsequently discharged through a load so as to generate a pulse, the pulse amplitude is stabilized by means connected from the junction of the inductor and diode to a point having a voltage lower than that of the power supply. As described, the PFN is charged from a 3-phase rectifier system D4 ... D9 via a smoothing circuit L3, C2, inductor LI and diode D1 and subsequently discharged via a load by triggering thyratron V1. The pulse amplitude is stabilized by triggering a thyratron V2 when the PFN charges above a predetermined voltage, so as to divert energy from the charging inductor L 1 into capacitor C1. This capacitor is subsequently discharged via D2 and L2 into the PFN during subsequent cycles. The connection of the cathode of V2 to the mid-voltage point of the supply permits stabilization at lower output voltages. Point X may alternatively be connected to an auxiliary power supply of lower voltage, adjustment of which controls the pulse amplitude. Fig. 4 (not shown) relates to an alternative 3-phase power supply comprising three bridge rectifiers providing tapping points at one sixth, one half and five sixths of the available D.C. voltage.

Title: Improvements in and relating to the production of porous and/or spongy masses or articles of rubber and rubber-like material
IPC: C08L21/00
Filed: 1937-06-18
Abstract: Porous masses are obtained by frothing positively charged, i.e acid, aqueous dispersions of rubber or rubber-like materials such as thiokol or neoprene by the generation or liberation of gas therein and setting the resulting froth, if desired after rendering the froth alkaline.  The dispersion may be prefrothed, e.g. by beating prior to the main frothing operation and this prefrothing may be effected with negatively or positively charged dispersions.  The frothing may be effected by chemical means, e.g. by the decomposition of salts such as carbonates, bicarbonates, sulphides, or sulphites which liberate gas under the action of acid, or by physical means, e.g. by the volatilization under heat and/or by pressure reduction of a volatile solid or a volatile liquid or gas adsorbed on a solid adsorbent. Thickening agents such as alginates, casein or glue may be added to the dispersion prior to frothing.  The froth may be incorporated with fibrous material, e.g. as described in Specification 489,031.  The frothing may be effected in a mould having means for automatically closing the container when it is full of froth as described in Specification 484,798.  Specification 489,031 also is referred to.

Title: Improvements in or relating to the Manufacture of Metal Wheels.
Inventor: DITTMAR FERDINAND CAMILLO
IPC: B21D53/26
Filed: 1919-07-09
Abstract: 136,493. Dittmar, F. C. July 9, 1919. Disk wheels.-Wheels are constructed from standards I, T, or channel-sectioned bars by cutting the web so as to leave spoke-forming parts 6, and bending the bar into circular form so that the flange 5 of the bar forms the wheel rim and the spoke members converge towards the centre. When I-sectioned bar is used, the material is cut to utilize both flanges and all the material of the web in the formation of two wheels. The spokes are splayed alternately in opposite directions, and a hub inserted before the ends of the rim are closed and welded together. The spoke members are then welded to the hub. The inner ends of the spoke members are preferably wider than their outer ends and are curved to the periphery of the hub, thus leaving the short web under the rim curved inwardly between the spokes as at 18', Fig. 8. In one construction, the wheel centre comprises a hollow ring 12, Fig. 2, which may be strengthened by webs 13. The wheel is secured to a hub 14 by bolts 16 between a fixed flange 17 and plate 15. In another construction, the spokes are weld'ed to annular plates 21 in line with the spokes and welded to a hub 23, which is preferably annularly indented as at 24. When the parts of the wheel are assembled and welded, the indentation is pressed out to put the spokes under tension. Special sections of bar may be rolled to give the desired character to the rim.

Abstract: 464,068. Belt fastenings. JONES, E. J. June 22, 1936, Nos. 17259, 22379, and 22685. [Class 80 (i)] Relates to a fastening for wide conveyer belts of the type comprising two U-shaped sheetmetal plates 2a having cut-out portions forming lugs, which may be interleaved to receive a hinge-pin, the limbs of the plates 2a being drawn together by bolts and nuts 5, 5b. According to the invention, the plates have ridges, bosses, or other projections 8 adapted when the bolts are tightened up to embed themselves into the belt ends. In the form shown, ridges of sinuous form are provided which wind in and out among the bolt holes, but straight ridges or rows of bosses between the holes may be employed. The conical heads 5a of the bolts are received in countersunk stamped holes in the plates 2a. The countersinking may be surrounded by an annular bulge, thus forming an annular recess on the inside face of the plate, into which recess the material of the belt is forced. A salient exterior edge is preferably formed round the bulge on the inner face of the plate 2a. To hold the bolts against rotation nibs 7 are turned up from the countersinkings into the holes to engage slots in the bolt heads, or nibs on the bolt heads may engage recesses or slots in the countersinkings. Alternatively, the bolt heads may be of oval, square, or other non-circular shape to engage corresondingly shaped recesses. Oval - headedbolts. are arranged with their longest diameters across the belt. In further forms (i) the bolt heads are circular, but the shank of the bolt is of square or other non-circular shape immediately below the head, to engage a similarly-shaped hole ; (ii) the bolt heads are flat and are serrated on their inner surfaces to engage shallow depressions in the plates 2a.
