Filed: 1956-07-09
Abstract: 816,615. Floating toys. ROSEDALE ASSOCIATED MANUFACTURERS Ltd. Oct. 9, 1957 [July 9, 1956], No. 21174/56. Class 132(3) A floating toy comprises a buoyant body 10 formed with a cavity 11 open at its bottom and closed at its top by a wall 12 having a relatively small aperture 13 so formed therein that the passage of air therethrough produces a whistle or similar sound. The body 10 may be formed in two hollow halves secured together either by fusion of their edges or by an adhesive. Alternatively the apertured wall 12 may be formed separately from the body, for example of thermoplastic material. Agitation of the water on which the toy floats gives rise to an intermittent flow of air through the aperture 13 which produces a whistling sound. The Provisional Specification mentions a moulded plastic or aluminium whistle.

Abstract: 479,440. Valve circuits for wireless reception. JOHNSON, G. W. (Philco Radio & Television Corporation) Aug. 4, 1936, No. 21487. [Class 40 (v)] In a receiver a feedback circuit is provided and applied to the input of the audio frequency amplifier and to the detector to control the amplification and degree of modulation respecttively. The Figure shows a feedback from the output to resistances R1, R2 which may be arranged to vary with frequency as by the provision of a shunt condenser C1. The feedback path may also include one or more impedances dependent in value on current flow to give volume expansion or contraction as described in Specification 479,485. A tungsten filament lamp may be used as a non-linear impedance. As shown the feedback is regenerative to the detector and degenerative to the amplifier V1. In a modification the diode cathode is connected to the remote end of resistance R2 so that both the amplifier and the detector are degenerated giving the effect of decreasing the percentage modulation. Volume control by potentiometer P will vary the relative feedback to the detector.

Abstract: 934,357. Free piston compressors. H. JANICKE, June 20, 1960 [July 1, 1959], No. 21627/60. Class 7(2). In a free piston compressor in which the gas to be compressed is admitted under pressure into the compressor cylinders 37 and in which the energy required to effect compression in the engine cylinders is derived from outwardly disposed compression chambers, the rear surface of each of the compressor pistons 24 is suitably dimensioned so that these pistons perform work during the inward stroke and absorb energy during the outward stroke the ratio between the front and rear surface areas of the pistons being selected in such a manner that an approximately constant compression ratio is obtained in the engine cylinders. As shown the compressor inlet pressure acts in spaces 38 at the rear of the compressor pistons. In a modification the delivery line pressure of the compressor acts in these spaces. In another modification the compressor pistons are double-acting and the gas supply to both sides of the compressor pistons comes from a common inlet conduit. In this modification the compressor is designed for operation with a high admission pressure and a relatively high compression ratio. The invention is applicable to multi-stage compressors. German Specification 924,114 is referred to.
