Title: Improvements in or relating to electrical musical instruments
IPC: G10H3/10
Filed: 1935-03-18
Abstract: 453,846. Electrical musical instruments. COMPTON ORGAN CO., Ltd., J., Chase Road, North Acton, London, and BOURN, L. E. A., 22, Stanwell Road, Ashford, Middlesex. March 18, 1935, No. 8347. Addition to 403,444. [Class 88 (ii)] In an electrical musical instrument wherein undulating potentials corresponding to individual partials of the notes are produced by electrostatic induction and converted into sound and wherein a single electrode corresponds to different partials of a number of notes, as in the parent Specification, an additive effect is produced when more than one of the keys of these notes is depressed, by the insertion of resistances whereby the potential of the electrode may be equivalently augmented. In the Figure the wave-form ring electrode 2 which co-operates with a rotary arm as in the parent Specification, is connected through high resistances 3 (two megohms) to silver wire contacts 4 on the pull-downs 1 of the keys of those notes of which the ring 2 represents a partial. Normally, these contacts 4 are in contact with bus-bars 5 connected to earth at 5a. On depression of a key, its pull-down 1 brings contact 4 against a particular bus-bar 6 energized to the strength of that order of partials for which the ring 2 is required. The bus-bars 6, each representing an order of partials, are connected to earth through low resistances 7 (100,000 ohms) and are energized to the required strengths by contacts 12 on stop pull-downs 8, through appropriate feed resistances 13. As shown, if one key only is actuated, ring 2 is connected to one bus-bar 6 through one resistance 3, but is still connected to earth through three resistances 3 in parallel. If two keys utilizing ring 2 are depressed, the ring is connected to two bus-bars 6, in each case through a resistance 3, and to earth through two resistances 3 in parallel, so that its potential is increased. A condenser 9 is connected between each ring 2 and earth to diminish "key-clicks." If this condenser is made large to produce a die-away effect, a rectifier 10 is inserted to avoid also delaying the build-up of the note ; a shunt resistance 11 then controls the die-away. In a modification, Fig. 3 (not shown), the resistances 7 and connections to earth of the bus-bars 6 are omitted, the bus-bars 6 being permanently connected to the keycontacts 4 each through a high resistance. Actuation of a key-contact 4 merely breaks the connection from a bus-bar 6 through the high resistance, key-contact 4 and bus-bar 5 to earth, leaving effective the connection from the bus-bar 6 through the high resistance, keycontact 4 and one resistance 3 to the ring 2. Specification 433,050 is referred to.

Abstract: 576,446. Destroying land mines. GRAY, W. T., RAMSDEN, H. K., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd: July 3, 1941, No. 8426. [Class 9 (ii)] [Also in Group XXXI] A self-propelled, light, unmanned vehicle of the endless-track type, and preferably having its propelling motors controlled by a trailing cable from a remote point, carries a compacted explosive net, preferably as described in Specification 576,445, and means for laying the opened net over a mined land area with the object of destroying the mines by exploding the net. The vehicle shown in Figs. 2 and 3 has endless tracks 12 driven by electric motors 13 supplied with current from storage batteries 30, the motors driving the tracks through multiple reduction gears and elevated fore-andaft wheels 17. The load is taken by sets of independently sprung rollers 18 on pairs of bogies arranged in fore-and-aft line on each side of the vehicle. The vehicle carries a laterally-compacted net on a drum 7 and the net is manufactured, extruded and spread in flared guides 127 with the aid of an endlesschain pusher 35, as described in Specification 576,445. The relays 28 for effecting steering, for operating the clutches for controlling the extrusion of the net and for firing the net, are controlled from a distant point 5, Fig. 1, by a cable 4 wound on a drum 24. The control is such that the net starts to be laid after the vehicle has travelled, say, 120 yards, then, after laying the net for 50 yards, the vehicle proceeds a further 15 yards before the net is exploded. After explosion, the cable can be repaired and, by swinging aside the extruder, the battery can be exchanged and the net drum 7 replaced, the vehicle being then ready to lay another stretch of net. Specifications 7222/15, 134,090, [both in Class 9 (ii)], 219,629, [Class 38 (iii)], 576,300 and 576,447, [Group XXXVII], are referred to.

Title: Expandable thermoplastic polymeric particles
IPC: C08J9/20
Filed: 1964-03-03
Abstract: Thermoplastic polymeric (e.g. polystyrene) particles (e.g beads) containing uniformly distributed throughout them as an expanding agent, water droplets averaging 5-40m  dia., may be prepared by incorporating water as a fine dispersion into the monomer or monomers to be polymerized, and subsequently effecting a suitably catalysed suspension polymerization of the resultant water-in-monomer emulsion in an aqueous medium.  The suspension may contain emulsifiers and stabilizers, e.g. ester of an aminated fatty acid mannitol dioleate, methanol, N-vinyl pyrrolidone/methyl acrylate copolymer, polyvinyl alcohol, CMC, water soluble starch, BaSO4 calcium silicate and also foamed polystyrene, or a graft polymer of styrene and ethylene oxides.  The polymerization may be catalysed by benzoyl peroxide, tert-butyl perbenzoate, di-tert-butyl peroxide, a -a 1-azobis-isobutyronitrile and/or dicumyl peroxide. Fire retarders e.g. tris-(dibromopropyl)-phosphate dyes and pigments are optional additives. There may additionally be present in the particles a gaseous, volatile or gas-forming compound which is insoluble in water, e.g. pentane or air.  Petroleum ether of b.p. 30-70 DEG  C. may be added during the polymerization as an anti-coagulant; the volatile compound specified above may also be added at this stage. The particles may be foamed by; (a) heating in a perforated closed mould; (b) extruding at a temperature above the softening-expanding temperature of the particles.  They may also be partially expanded e.g. by steam treatment, before finally foaming as above.  The particles may be stored, especially if they contain a volatile liquid, for a time sufficient to allow part of this liquid and for the water to evaporate and be replaced by air. The expanded products have a low density, e.g. of the order of 10-15 Kg/M3.
