Title: Method of making thermoplastic sheet material
Inventor: SAUL WALTER
IPC: B29C48/06
Filed: 1964-08-13
Abstract: 1,121,654. Moulding tiles. DUNLOP SEMTEX Ltd. 27 July, 1965 [13 Aug., 1964], No. 32961/64. Addition to 1,088,844. Heading B5A. Thermoplastic sheet material, e.g. a tile, having a terrazzo appearance, is formed by moulding a conglomeration of small pieces of the material, the majority of which each exhibit 2 or more colours, or shades of the same colours, in a stratified manner. The pieces are formed by slicing an extruded variegated rod, or set of rods, in a direction transverse to the direction of flow during the extruding and the slices may, if required, be further subdivided. The moulding may be performed on a base sheet, of e.g. P.V.C., which is retained upon the finished sheet, or the slices may be embedded in a compatible thermoplastic mortar or matrix.

Title: Low pressure mercury vapour discharge lamp with amalgam
IPC: H01J61/72
Filed: 1974-07-26
Abstract: 1471454 Metal-vapour lamps PATENT TREUHAND GES FUR ELEKTRISCHE GLUHLAMPEN mbH 26 July 1974 [1 Aug 1973] 33036/74 Heading H1D In a low pressure mercury vapour discharge lamp, preferably a fluorescent lamp, an amalgam determining the equilibrium vapour pressure in operation of the lamp and containing more than one metal (apart from Hg) contains an alkali metal or an alkaline earth metal (e.g. Mg). The amalgam may also include In, Pb, Cd, Su. The proportion of In may be 5-50 mol per cent, preferably 5-40 mol per cent, with 5-40 mol per cent Hg. A particular amalgam for lamps which are thermally highly loaded contains 1 mol Hg, 6 mol In and 1 mol Mg. For high power lamps, the amalgam may contain 1 mol Hg, 10 mol In and 1 mol Hg. Mg can be substituted for In reducing the amount of In by about 40%, which reduces cost and has other advantages. As shown in Fig. 1, a lamp with an envelope 1 carrying a fluorescent layer 2 has at each end a stem 3 carrying the electrodes and having a flare 4. The amalgam is applied to flare 4 in the form of a ring 10. The width of ring 10 may be 3 mm., and quantity of Mg, 1À2 mg and of In, 34 mg. 20 mg Of Hg is introduced into the lamp. The amalgam formed contains 1 mol Hg to 7 mol of Mg-In alloy. A metal cylinder 11 surrounding the electrode carries an amalgam-forming alloy 13 including In to facilitate run-up. Alternatively, the amalgam (15) of composition Hg 1 In 10 Mg 1 , is carried by an iron foil (14) (Fig. 2, not shown) disposed around the stem and supported thereby by means of a wire. The lamps have a light flux which varies little with changes in the internal temperature.

Title: Waveguide impedance measurement
Inventor: WILLIAMS THOMAS ARTHUR KENNEDY
IPC: G01R27/02
Filed: 1959-09-29
Abstract: 883,877. Impedance measuring. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 27, 1960 [Sept. 29, 1959], No. 33054/59. Class 37. In an impedance measuring device two standing wave detectors are fed from a common source, one detector having coupled to it the waveguide component to be tested, and the other detector having coupled to it an adjustably short-circuited waveguide. The output of the detectors is combined and fed to a phasesplitter and phase-sensitive detectors whose outputs are applied to crossed coils of a C.R.T. from whose face the phase and magnitude of the reflection coefficient produced by the said waveguide component can be read. A standing wave detector comprises a rectangular waveguide coupled to a circular waveguide, in which is a rotatable element to measure the elliptical polarization in the circular waveguide produced by standing waves in the rectangular one. Variation in signal due to one rotation correponds to variation in magnitude of the standing wave pattern in the rectangular waveguide over one wavelength. Specifications 592,224, 757,402 and 773,527 are referred to.

Title: Improvements in and relating to sutures for surgical and other needles
IPC: A61B17/06
Filed: 1931-11-30
Abstract: 378,288. Sewing threads. LYDEARD, E. H., Randwick, Plymouth Road, Redditch, Worcestershire. Nov. 30, 1931, No. 33163. [Class 112.] A suture or sewing thread for spring-eyed surgical or other needles is characterized by an eye at one end for engaging with the eye of the needle. When the suture is of catgut, silk, linen thread, silk-worm gut, or Japanese gut, an eyed ferrule is attached thereto, but in the case of a silver or other metal wire the end of the wire itself may be provided with the eye. The eye may be circular, rectangular or triangular in shape. Various constructions of ferrules are described. They are preferably of metal, but may be moulded, for example, from the composition known by the registered Trade Mark " Bakelite." That shown in Fig. 3 is obtained by suitably stamping and drilling a tube of silver or other non-corrosive metal. Smooth shoulders 6 are produced. The suture 8 is introduced into the ferrule, and is fixed by crimping the ferrule, or by an indented annulus 7 produced by suitable pliers. In a modified form, Fig. 9, a split tubular socket 1b is formed and closed upon the suture as described in Specification 288,425, [Class 112, Sewing &c.], for eyeless needles. In this and other modifications, the shoulders 6 may be of annular form instead of on each side of the ferrule. A modification shown in Fig. 5 comprises an eyed tubular or solid member 1b suitably roughened at the area of contact with the tubular member 1a ; the junction of the two is effected by crimping or spinning down the end of the tube la at 10. In a further modification, Fig. 8, a loop 3a of rustless steel, silver or other metal is secured to the tubular element 1a. The eyes are not necessarily throughway apertures, but may be provided with a web 3c as shown in Fig. 13.
