Patent GB-228894-A (GB)
Abstract: 228,894. Thygesen, N. P. Feb. 5,1924, [Convention date]. Balls.-A ball having an inflatable rubber bladder and an outer case of cloth or the like, has one of the sections a of the case left free near the pole b to form a closing flap c, and the case opening is spanned by a tongue e sewn to the adjacent sections. An opening h is left between the flap c and the tongue e for the insertion of the bladder. The inflating tube d of the bladder is passed through a hole g in the tongue e, and after inflation the air is retained by folding the tube and tucking it under the case. The closing flap c is secured in its closed position by means of a hook i and eye j.

Title: Improvements relating to asymmetric conductors
IPC: H01L21/16
Filed: 1947-08-20
Abstract: 626,262. Detectors. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Aug. 20, 1947, No. 23056. Convention date, Aug. 21, 1946. [Class 40 (v)] A radio detector comprises an asymmetric conductor consisting of a composite body having a zone a of pure cuprous oxide, a zone b of cuprous oxide containing an excess of oxygen and a zone c of metallic copper obtained by reduction of the cuprous oxide. The counter electrode 3 may be a simple or multiple point of iron-nickel-chromium alloy rod or wire. Alternatively, contact may be made with the lateral surface of a rod or wire, which may be rendered yielding by twisting or spiralling. The asymmetric conductors are formed by placing discs of copper on a refractory support in an oxidizing furnace at a temperature of above 1000‹ C., and, after cooling and tempering, effecting a superficial reduction to metallic copper of the surface which was most remote from the refractory support, for example by electrolysis.

Title: Method for the production of blocks or bricks
IPC: C04B28/20
Filed: 1976-06-10
Abstract: In masonry bricks, the heat insulation can be increased by reducing the apparent density. However, this is at the expense of the strength of the blank. In order to obtain a reduced apparent density without impairing the strength of the blank, at least 1% by weight of cement, preferably fast-setting cement, is added to the raw mixture of sand, lime and water. In this modified mixture, strength-forming reactions of the cement are allowed to start by leaving the mixture to stand for, for example, 1 hour before compaction. Subsequently, the mass is compacted in a compacting device to give blanks, the pressures applied being low as compared with 150 kp/cm<2>. In this way, lime sand bricks can be obtained which have a proportion of more than 25% of voids and a strength of more than 1 kp/cm<2> and which can be handled without being damaged.

Title: Improvements relating to electronic switching circuits

Abstract: 710,717. Pulse circuits. METROPOLITANVICKERS ELECTRICAL CO., Ltd. Oct. 14, 1952 [Oct. 16, 1951], No. 24121/51. Class 40 (6) A sequence switching circuit comprises a series of thermionic valves which are rendered conductive in sequence to effect switching operations, the control grid of each valve being connected via a resistor-capacitor network to the anode of the preceding valve and also to a synchronizing source so that when a valve conducts and is then cut-off the next valve is rendered conducting until it is itself cut-off by a negative-going synchronizing voltage. Fig. 1 shows a switching circuit in which the sequential conducting of valves V1-V3 is controlled by pulses Fig. 2(c) derived from a synchronizing circuit itself controlled by a synchronizing pulse generator. A starter circuit controlled by the synchronizing pulse generator generates a positive-going pulse, Fig. 2(a), which causes valve V1 to conduct and produce a negative pulse, Fig. 2(b). At the anode this is differentiated by the resistor-capacitor circuit C1, R2, R3 and the synchronizing pulses are superimposed to produce a waveform as shown at Fig. 2(d) at the control grid of valve V2. Thus after one complete cycle of the synchronizing pulse waveform valve V1 is cut-off and the valve V2 conducts to produce a negative pulse Fig. 2(e) at its anode, this process continuing down the chain which if required may be made into a closed loop by driving valve V1 from the last valve in the chain. To. prevent the possibility of more than one pulse circulating in the ring at any instant a negative pulse may be applied to the control or suppressor grids of at least half of the valves in the ring when a given valve in the ring is conducting.

Forward sparking between the brush and the fixed contact towards which it is approaching is thus prevented. Fig. 1 shows a part of a distributor consisting of a rotary arm 14 carrying a brush 15 which passes over fixed contacts 12. An insulated conducting element 32 is fixed to the arm 14 on that side of the brush 15 nearest to the contact 12 from which the brush is reading. Instead of the conductor 32 being carried by the brush arm a conductor may be placed near each of the contacts 12 on that side nearest to the brush arm as it recedes. The parts of the brush and conductor 32 which extend above the surface of their support may be shrouded in insulating material. The distributor is described in connection with an ignition system for internal combustion engines of aircraft in which low tension boosting is used to facilitate starting.

Abstract: <PICT:0826208/IV (a)/1> Fusible microspheres of synthetic resin for use as a binder in the manufacture of an abrasive wheel, are prepared by conveying dry ground fusible resin particles by a turbulent gas at a temperature substantially below the melting point of the resin, into one end of a mixing chamber to be entrained by a hot turbulent gas stream at a temperature substantially above the melting point of the resin so that the resin particles are formed into microspheres which pass to the periphery and opposite end of the mixing chamber, there to be entrained by a turbulent gas at a temperature substantially below the melting point of the resin.  The gas or gases used should be substantially unreactive to the resin.  The latter may consist of a phenolaldehyde resin of resol or Novolak type, which may be modified by the addition of 10 to 20% by weight of a thermoplastic resin such as a polyvinyl ether or ester, e.g. polyvinyl acetate or chloride, a copolymer of vinylidene chloride, and vinyl chloride, a partial formaldehyde or butyraldehyde acetal of hydrolysed polyvinyl acetate, polystyrene, or a copolymer containing styrene.  Resin particles ground to 2 to 200 microns in diameter are fed to a conveyer tube 6 from a vibratory trough feeder, and are propelled turbulently into the upper end of a mixing chamber 1 by cold air supplied through jets 8.  Hot air at about 100 DEG  to 300 DEG  F. above the melting point of the resin is supplied through a conduit 3 to be rotated by vanes 7 about the outlet of the tube 6.  Additional cold air is introduced through pipes 9 tangentially into the chamber 1 in counterflow to the hot air stream, to maintain the microspheres dispersed, and to cool them as they pass to the outlet 12 and thence to a cyclone separator 13.  Air is drawn through the system by a blower 16. Specification 556,126, [Group IV], is referred to.
