Abstract: 696,391. Folding toys. ROWNTREE & CO., Ltd. March 13, 1952. [April 16, 1951] No. 8865/51. Class 132 (iii). [Also in Group XVIII] A collapsable dummy comprises a tube 1 of resilient material which can be folded flat and foldable distance pieces 4, 8 for supporting the tube when distended, the distance pieces being connected by a strut 12 so as to be simultaneously folded or simultaneously unfolded and at least one of them having an axis longer than the corresponding dimension of the tube so that when the tube is distended that distance piece is buckled and the strut is in tension so locking the dummy against accidental collapse. The distance pieces have each a diametrical score-line 5, 9 about which they can be folded upwardly and they are hinged to the tube by tabs 6, 7, 19, 11. The tube has two score lines by which it can be collapsed which, when the tube is distended are adjacent the ends of the score-lines 5, 9 on the distance pieces. The top distance piece 4 is circular in shape and the bottom distance piece 8 is oval, the larger axis of the oval being on the score line 9 and constituting the axis about which the distance piece buckles. The top distance piece has a finger hole 13 for collapsing the dummy and a removable lid 14 spaced from the distance piece by a member 15 may be provided.

Inventor: SCHWAIGER JOHANN
IPC: B44C3/12
Filed: 1966-03-01
Abstract: A flat sheet material consisting of textile, metal or synthetic resin threads, produced by weaving, lace or net production, or knitting, or of leather, metal strips, wood, synthetic resins has mounted thereon synthetic resin bodies in such a manner that projections formed on these bodies on their rear side are passed through the flat sheet material and are deformed in the manner of rivets on the rear side. The bodies may comprise mountings carrying glass, jewels or reflector elements. The projections may comprise pins, pegs, lugs.  Passages for the projections may be prepared by punching, pressing, drilling. The riveting is obtained by heat deformation of the projections.  The bodies may be connected by threads or webs to form an ornamental group or strip of decorative bodies before attaching to the sheet material.  Some or all of the connecting threads or webs may be removed before attaching the material.  In Fig. 2, decorative bodies in the form of mountings 3 and 31 supporting gem stores 2 and 21 are fastened on the supporting material 1. The mounting 3 of each body is formed at its underside with a pin 5 which is deformed on the underside of the supporting material to form a rivet 51.

Title: Gas separators for liquids to be metered
IPC: B01D19/00
Filed: 1936-03-26
Abstract: <PICT:0471939/III/1> A device for separating gas from liquid to be metered comprises a casing 8 through which the whole flow of liquid passes entering from below at 5, reversing its direction and leaving by the annular passage 6.  A float 11 is mounted on a vertically guided stem 10 and by means of a crank 18 rotates a disc valve 14 having ports co-operating with those in the fixed surface 13.  The ports may be tapered so that successive units of closing movement produce diminishing reductions of port opening.  The float 11 descends into a dish 9, the liquid contents of which cushions its fall.  The Provisional Specification describes also the use of slide valves other than disc valves, e.g. sleeve valves, and states that a supplementary poppet valve may be fitted to deal with small quantities of gas.

Title: Improvements relating to frequency and phase control systems
IPC: H03L7/107
Filed: 1955-03-29
Abstract: 788,114. Automatic frequency and phase control systems. GENERAL ELECTRIC CO. March 29, 1955 [March 29, 1954], No. 9162/55. Class 38 (4). Synchronism is established between a reference oscillation, e.g. the line synchronizing pulses of a television receiver, and a controlled oscillator 45 by applying synchronous sawtooth waves derived from the controlled oscillator and the reference oscillation to a phase detector 1 with output applied to phase lock the oscillator 45 through a low-pass filter 36 having rectifiers 34, 35 in series with the shunt smoothing capacitors 32, 33, which become blocked when the oscillations differ much in frequency, so that the capacitors 32, 33 are effectively isolated from the filter and the pull-in frequency range of the system increased. Conversely, on the frequencies being nearly equal, due to decreased output from the phase detector to the filter and continuous leakage from the capacitors through leak resistors 36, 37 the rectifiers again becoming conducting to introduce fully again the capacitors 34, 35. A capacitor 29 by-passes the spikes due to the sampling or clamping action of the phase detector 1. Resistor 30 and capacitor 31 also provide integral control. In a modification a single leak resistor bridges the capacitors 32, 33. Further, a series resistor precedes the input to the filter, and a shunt resistor. is in series with the filter.

[Class 38 (v)] [See also Group XXXVI] A connector for an electric iron is provided with a switch which is normally automatically operated to open the circuit when the iron is stood on end but which may be adjusted so as to keep the circuit closed. The connector comprises two socket contacts in the form of springs 4 which terminate in contacts 5 which normally engage fixed contacts 8. The contacts 5 are mounted in an insulating member 6 having a cavity 12 in which moves an arm 13 loosely mounted on a shaft 10 which is bent round where it emerges from the connector to form an operating handle. When the iron is placed on end the handle 10 is moved in the direction of the arrow, Fig. 1, and a lug 15 on the shaft 10 positively drives the arm 13 to move the member 6 to the left, Fig. 2, thereby separating the contacts 5 from the contacts 8. When it is desired to leave the circuit closed, the arm 10 is moved into the dotted line position, Fig. 1, against the action of a spring 4 connecting the arms 10, 13.
