Title: Improvements in belting for supporting garments
IPC: A61F13/64
Filed: 1929-03-28
Abstract: 329,450. Kleinert Rubber Co., I. B., (Assignees of Guinzburg, V.). Dec. 7, 1928, [Convention date]. Belts; materials for wearing. apparel; fastening wearing-apparel. -Belting material for supporting garments which is extensible only in the direction of its length consists of a strip of rubber-coated stockinette or the like which is folded over with the rubber faces 11 in contact and joined by stitches 15 which penetrate one layer only; the mid portions 14 are then united by means of a knurled roller and vulcanized so as to leave tubular edges 13. In a modification the abutting edges of the folded strip are left unjoined or are joined by adhesive tape. In another modification the folded strip is stitched through just inside the tubular edges. In another modification, the material is folded on its mid line so as to produce only one tubular edge. The material may be incorporated as a waist-belt in undergarments.
Patent GB-531887-A (GB)
Title: New or improved method and apparatus for determining the length of webs of material
IPC: B65H45/101
Filed: 1938-04-01
Abstract: 531,887. Folding fabrics &c. MONFORTS, J. April 1, 1938, No. 10034. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 3, 1938.] [Class 42 (ii)] In a cutting apparatus having a laying-sword and grippers for holding the end of each fold, the contraction of the first layer effects the adjustment of stops &c. 8 which determine the length of the stroke of the laying-sword, so that subsequent layers are of the correct length desired. The stops &c. 8 may also be adjusted according to the thickness of the web 5 being laid. When the thickness feeler 1 is allowed to feel the web 5 by the cam 2 this cam closes the circuit of a motor M1 which travels a nut 6 along a screw 60. The nut 6 first closes a switch 7 to start a motor M2 and then opens a switch 11 carried by the feeler 1 to stop the motor M2. This motor M2 rotates the screws 10 to adjust the stops &c. 8. When the contraction detector 13 is dropped on to the web 5 by the cam 14 this cam also closes a switch 16 and starts a motor M3. The motor travels a nut 17 which first closes a switch 18 to start a motor M4 and later opens a switch 19 carried by the detector 13 which has been oscillated to the position shown in Fig. 1 by the contraction of the web. The opening of the switch 19 stops the motor M4. The motor M4 is geared as by a chain 9 to the screws 10 which adjust the stops &c. 8. As shown in Fig. 5, the laying-sword is traversed in one direction by a pawl and chain 27, 29 and in the other direction by a pawl and chain 28, 30 the adjustable stops &c. 8 throwing over the pawls at the end of each stroke. In its adjusted position, one stop &c. 8 will touch one contact 32, or 33 of a motor M5 which, on closing of the hand switch 34, will return the stops &c. 8 to their normal positions shown in full lines.

Title: Data transformation and raster scan plotting system
IPC: G09G5/42
Filed: 1976-03-12
Abstract: 1507013 Graphical recording; cathode-ray tube circuits GEOSOURCE Inc 12 March 1976 [20 March 1975] 10044/76 Heading G4H [Also in Division H4] To produce a graphical output record, a processor operating as a peripheral to a computer determines in which strip(s) of the record a given positional plot command requires plotting to occur and generates sub-commands accordingly, the sub-commands and a raster scan representation also derived by the processor being stored in a random-access memory, the raster scan representation then controlling a raster scan plotter to produce the record. The plotter may be a CRT or electrostatic plotter which can be moved parallel to the axis of a rotating drum bearing the (photographic) record medium to record a strip per revolution of the drum. An indicium to be recorded need not lie wholly within a single strip. Positional plot commands from magnetic tape go via the computer to the processor to determine in which blocks of which strips (there being a plurality of blocks per strip) recording is required, to generate sub-commands (e.g. end-points) accordingly, which go via the computer for storage (according to strip and block) in a first area in the random access memory (magnetic disc file). The sub-commands are then used by the processor to generate raster scan representations which are stored in a second area in the random access memory prior to use to control the plotter. Two types of information may be recorded on the same record, e.g. multi-channel seismic data and annotations, in which case the processing is done for the two types in turn and the raster scan representations are superposed in the memory before use by the plotter.

Title: Manufacture of lenses
IPC: C03B23/22
Filed: 1933-04-04
Abstract: 418,981. Making lenses. CULVER, E., 42, Coolhurst Road, Crouch End, and EMERSON, A. H., 24, Wentworth Park, Finchley, both in London. April 4, 1933, No. 10103. [Class 56.] A lens is formed by dropping two plates of glass over part of their area or dropping them irregularly over its whole area in order to effect a distortion in the contacting surfaces of the plates and the lens is then finished with regular surfaces. If two plates of glass of different refractive indices are used the dropping of the lens blank can be arranged so that the final lens varies in power in various zones as required. If two plates of different colours are used a colour filter varying in colour in different zones is obtained. The blank may be formed with a plane lower surface and placed on an irregular former for dropping as shown in Fig. 1<a>. On the other hand the irregularity may be formed in the bottom surface of the lens blank and it may be dropped on a plane former as shown in Fig. 6<a>. The two plates may be fused together in the dropping operation by raising the temperature sufficiently high.

Abstract: 1,187,367. Obtaining metals and alloys. HALOMET A.G. Feb.27, 1969 [Feb.28, 1968], No.10614/69. Heading C7D. Metal is produced by reduction of metal halide with a reducing metal in a closed reactor, the reaction temperature being above the melting point of the metal to be produced and the vapour pressure being at least equal to the vapour pressure of the melt formed during the reaction. As shown, Ti is produced in a reactor having a water-cooled double steel wall 1 having over its lower part a magnesium spinel layer 2. Liquid Mg and TiCl 4  gas are introduced through graphite tubes 3, 4 respectively. Liquid MgCl 2  is withdrawn through tube 7 and liquid Ti is drained through tube 8. The desired reaction temperature is maintained by controlling the temperature of the TiCl 4  vapour. In the other example, a batch product of solid Zn is obtained by reacting ZnBr 2  with Al. The process may be also used (a) to produce the metals Be, Cr, Hf, Ir, Mn, Mo, Nb, Ta, Th and Zr; (b) to produce alloys by reducing a mixture of halides, either together or sequentially; and (c) to produce alloys by introducing an alloying metal in its elementary state into a halide reduction reaction.

In a synchronous detector in which signal of carrier frequency is used in demodulation and is derived from the incoming modulated signals, means are provided to prevent phase reversal occurring when the incoming signals are overmodulated. The modulated signals are applied to a phase-splitter PN (Fig. 4, not shown), providing two outputs, one unchanged in phase and the other reversed in phase, which are applied to gates G1, G2 respectively. The outputs from these gates are combined and fed to the device deriving the carrier frequency. The incoming signals are also fed to a device PD which senses the relative phase of the carrier and opens gate G1 or G2 according as the carrier is of normal or reversed phase. The arrangement may be applied to a diplex system of the type in which the two signals are modulated upon the same carrier frequency with a relative phase-shift of 90 degrees (Fig. 5, not shown).
