A ceramic body, composed for example of Al 2 O 3 , BeO or MgO, is metallized with a layer composed of MoO 3 , MnO 2  and TiO 2  as described in Specification 844,171. The layer may otherwise include two or more of the elements Mo, Mn, Rh, W, Ti, Ta, Si, the oxides thereof and combinations of said elements and/or their oxides. The metallized layer, which may first be copper plated, is brazed to a copper-nickel alloy surface by means of an oxygen free, high conductivity braze material. The brazing is preferably effected at a temperature within the range of 200-300 C. below the sintering temperature of the metallizing material.

Leads 8 from the resistance are brought out through two holes in the plate 6 and an insulating block 10 is secured by a screw 9. The assembled heater is then subjected to high pressure between two plates to flatten the grooves 3 to obtain a large surface for heat transfer, and to form shallow grooves 7 in the plate 6. The spaces between the grooves 3 may contain metal strips of channel section, which after pressing combine with the grooves 3 to form a plane surface. The spaces enclosed by these strips may contain refractory material. The helical resistance wire may enclose a core of refractory material and be enclosed by a sleeve of similar material, the whole being crushed and compacted by the pressing operation. Reference has been directed by the Comptroller to Specification 515,560.

Abstract: 1,026,672. Electron beam apparatus. GENERAL ELECTRIC CO. Sept. 24, 1962 [Sept. 26, 1961], No. 36275/62. Heading H1D. [Also in Division G5] In a method and apparatus for reading out information stored in the form of deformations in the surface of a solid recording, e.g. thermoplastic, medium 13 by electron beam writing, a reading beam from gun assembly 12 is scanned across the surface and signals derived at collectors 35, 36 from the emitted secondary electrons and possibly also from a conductive backing film of the recording medium. Collectors 35, 36 may be replaced by electron multipliers. The same beam may be used for writing as for reading. The recording medium 13 comprises a plate supported on a turntable 14. A viewing window 15 is provided in the housing 11 for checking the electron beam and a Schlieren projection system 22, 23 is provided for visually checking the writing on the recording medium. The deformations in the surface of the recording medium are in the form of grooves which may be modulated in breadth, in depth or in deviation from a centre line. A differential signal derived from the secondary electron collectors may be fed back to the magnetic deflection coil 34 to keep the reading beam on the centre line of a groove. The surface of the recording medium may be periodically flooded with electrons to overcome the building up of charges on the surface.

Abstract: 1,109,601. Hall plates. SEISMOGRAPH SERVICE (ENGLAND) Ltd. 16 Sept., 1964 [16 Sept., 1963], No. 36352/63. Heading H1K. [Also in Division G1] A correlating member for use in apparatus for correlating two variables (see Division G1), is in the form of an elongate Hall plate structure, comprising an indium antimonide or arsenide Hall plate 21 bonded to a magnetic ceramic block 22 and then lapped to a suitable thickness. The block is then copper-plated, without coating the plate 21, and then etched away to provide the conducting loops 23. Controlled evaporation of copper may alternatively be used. One of two variables to be correlated is recorded on magnetic tape and arranged in position over the Hall plate to provide the operating magnetic field therefor. The other variable is recorded on a second tape and moved across the block 21 relative to the conductors 23. This movement induces currents in the conductors which pass through the individual parts of the Hall plate. At each part of the plate a voltage proportional to the instantaneous product of the two variables represented by the related parts of the magnetic tape is created, and the total voltage output from the extended plate gives the instantaneous correlation function.

Abstract: 1381965 Detachable furniture hinges R HEINZE [trading as RICHARD HEINZE] 4 Aug 1972 [1 Sept 1971] 36413/72 Heading E2F A furniture hinge assembly comprises the combination of a reception socket 16a, Fig. 7, in, on or adapted to be inserted in a door or wall of an article of furniture and a hinge, Fig. 6, having an insert member 1a, the insert member being received in said socket and being releasably retained therein by means of a bayonet coupling (24a, 25a). In the case of furniture formed of synthetic material, the socket may be formed integrally in the door or wall of the article. The socket 16a is provided with an axial slot 26a and the bayonet coupling includes surfaces which are oblique and cause the socket, upon rotation of the insert member in the socket, to expand in diameter and become firmly fixed in a bore 16a' in the article of furniture. Rotation of the socket in the bore is prevented by the provision of an axial rib 20, but alternatively, the external configuration of the socket and the bore may be hexagonal. The socket may alternatively be driven and/or glued in the bore. In an alternative embodiment, Figures 1 and 2 (not shown), the insert member is additionally provided with a pair of catch lugs (13) which engage in pockets (22) extending inwardly from the wall of the socket. The socket may be further provided with circumferential grooves (19), and an annular rim (30) which receives a flange 10 of the insert member, the flange 10 being for the purpose of concealing the coupling between the insert member and socket. The insert member 1a and hinge arm 2 are connected by hinge levers 5 and 6 which are pivotally connected to the insert member and hinge arm by pivot pins 3 and 4.

Title: Improvements in the treatment of polyethylene and like polyolefins and in products obtained thereby
Inventor: BARTRUM BASIL ECCLESTON
IPC: B29C71/04
Filed: 1958-05-28
Abstract: Uni- or biaxially stretched materials, particularly films, of polyethylene or like crystallizable polyolefines, are treated by subjection to high energy ionizing radiation to produce cross-linking insufficient to inhibit further orientation, heating the cross-linked material, and subjecting it while hot to uni- or biaxial orientation, and cooling.  "Like crystallizable polyolefines" includes polypropylene, copolymers of ethylene and propylene and copolymers, including graft and block copolymers, of ethylene or propylene with minor amounts of isobutylene, amylene, butadiene or 1- or 2-butene. In a preferred process, orientation is effected by stretching the material in the form of a tube by gas inflation between pairs of nip rollers or other restricting means, heating being effected by passing the tube through a hot liquid.  Film made by the process of the invention is heat-shrinkable and may be used for packaging foodstuffs and other articles, and for the production of balloons, squeeze bottles, bottle caps, gaskets, and bottle closures formed by shrinking the material on the neck of the bottle.
