Title: Improvements in color television voltage control system
Inventor: DRESSLER ROBERT
IPC: H04N9/26
Filed: 1957-12-16
Abstract: 872,543. Cathode-ray tub eoperating circuits. CHROMATIC TELEVISION LABORATORIES Inc. Dec. 16, 1957, No. 39076/57. Class 40(7) [Also in Group XL(b) ] In a colour television receiver utilizing a cathode-ray tube 13 of the type having a screen formed of a repeating sequence of component colourphosphor strips to which the electron beam is directed by means-of a structure made up of interleaved switching grids 102, 103, colour contamination during switching is avoided by maintaining the average potential of the grid structure constant whilst applying equal and oppositely poled switching pulses to the respective grids. Thus in the example described, which operates at field sequence, the average potential of the structure is that supplied by source 18 (4500V) but for switching to red, grid 102 is increased by 150V whilst grid 103 is reduced by 150V, and for switching to blue, grid 102 is reduced by 150V whilst grid 103 is increased by 150V. During green fields the two grids are maintained at the same potential, i.e. 4500V. The switching potentials are produced from pulses R and B occurring during the respective fields which are derived from the received signals via circuit 22. The pulses are applied to respective amplifiers 24, 25, phase inventors 26, 33 and pushpull circuit 27, 34. The resulting oppositely poled potentials are then applied across centre-tapped resistor combinations 31, 32 and 37, 38 which are connected together in the manner shown to the switching grids, and via network 41, 42, 61, 62 to source 18. Specification 732,238 is referred to.

Abstract: 1,203,273. Bolt fastenings. GENERAL ALARM CORP. 26 Aug., 1967, No. 39375/67. Heading E2A. [Also in Division G4] A lock for a door, &c includes a bolt slidable in a housing 11 mounted on the door and engageable in a keeper 16 mounted on the frame 17, the housing being so mounted that should the door be pushed inwards it is caused to rock about a fulcrum 41, tripping a switch 26, which passes through a slot 23 in housing 11, to complete an alarm circuit. The alarm may be within housing 11 or located remotely. Slot 23 is such that switch 26 remains tripped after the housing returns to its normal position. The alarm is thus reset manually. A chain connection may be made between keeper 16 and housing 11 by inserting, as shown, anchor 47 in a slot in housing 11. Forcible opening of the door beyond a short distance determined by the chain, whilst the bolt is retracted, rocks housing 11 about fulcrum 41 to operate the alarm. Anchor 47 may be so positioned as to engage a slot in the thumblever 38 of the bolt, thus preventing retraction of the bolt from keeper 16. A lamp may be provided in keeper 16 to indicate whether the bolt is retracted or extended, the bolt, when extended, engaging a switch in keeper 16 to open the lamp circuit. Reference has been directed by the Comptroller to Specification 1,081,782.

Abstract: 333,853. Wilsdorf, H. Dec. 24, 1929. Barrel and cylindrical hinges.-In a timepiece mounted in a secondary casing, the two parts of which are slid relatively before they can open about a hinge, the timepiece is mounted on one part by a spring hinge, but is restrained from rising when the case is open and released when the casing is closed. The upper part 2 of the secondary casing is spring-hinged at 5 to a plate 4 sliding parallel to a hinge 5 on a dovetail 3 of a part 1. The watch 8 is suspended by four springs in a frame 6 spring-hinged at 7 to part 1. A gate 13 on frame 6 co-acts with a lug 12 on plate 4. If the case is closed, parts 1 and 2 are slid relatively so that catch 10 on part 2 leaves the hole 11 in part 1. The case is then opened by the spring hinge 5 and at the same time lug 12 enters notch 13<1> to lock the watch down. To raise the watch the parts' 1, 2, now open, are slid back again relatively to one another, lug 12 is freed and hinge 7 raises the watch. When the parts 1 and 2 are closed the lug 12 frees, the frame 6, but rising of the latter inside the case is prevented by a plug 15.

Title: Improvements in the manufacture of artificial leather-like material
Inventor: FAIRCLOUGH JOHN HOLDEN
IPC: D06N3/00
Filed: 1959-12-09
Abstract: A process of manufacturing an artificial leather-like material comprises treating a non-woven web of fibres, of which at least 10% are synthetic polymeric fibres having a high degree of elasticity, with a non-aqueous dispersion of a thermoplastic polymeric bonding agent containing a plasticizer, heating to get at least partly the dispersion and then either (i) applying pressure to the web, one side only of which is hot enough to cause the binder to soften on that side, or alternatively (ii) passing the web through a sueding calender having at least two bowls of which one has an abrasive surface and is driven at a higher speed than that of the web, the finished material containing not more than 25% and not less than 10% by weight of fibres calculated on the weight of the finished product. Specified fibres are polyesters, nylon, cotton and viscose rayon. Specified binders are cellulose acetate, ethyl cellulose, polyvinyl butyrol, polyvinyl chloride or a copolymer of vinyl chloride and vinyl acetate.  The liquid component of the dispersion may consist either entirely of a plasticizer or a non-aqueous volatile liquid together with a plasticizer. Specified plasticizers are dioctyl or dibutoxy-ethyl phthalate, dicapryl adipate, dioctyl sebacate, trioctyl phosphate and linear polyester plasticzers.  The dispersions may be applied to the web by dipping or spreading followed by mangling.  The step of pressing the web, with a temperature differential between the two sides of the web may be carried out (i) by cooling one side of the web after heating to gel the dispersion and then pressing between cold rollers; or (ii) by heating one side only of the web, e.g. by passing the web between two pressure rollers of which one only is heated, or by pressing the web between a heated and an unheated plate; or (iii) by heating the web one side only, e.g. by contact with a hot plate or roller, or by infra red, and pressing between the cool bowls of a calender; or (iv) by reheating one side of the web after gelling and cooling, the reheated side being fused to a paper layer which is removed after calendering. In a further embodiment, a bonding agent is applied to the web which is heated and pressed before the application of the dispersion and subsequent heating and pressing.  Where one side of the web only is heated, a finely divided filler, preferably fibrous, e.g. of leather dust, powdered nylon or cotton, may be deposited on that side prior to heating, e.g. by incorporation in the dispersion.  The treated web may be embossed or passed through a sueding calender.  Seven specific examples are described. Specification 910,483 is referred to.
