Title: Improvements in Magnetic Cores
Inventor: OLSEN WILLY
IPC: H01F41/02
Filed: 1967-07-26
Abstract: 1,173,447. Making transformer cores; jointing. TELCON-MAGNETIC CORES Ltd. 26 July, 1967 [27 July, 1966; 19 May, 1967], No. 34371/67. Headings B3A and B3V. [Also in Division H1]  A magnetic core, e.g. for a transformer, is formed from two C-shaped core parts 1, 2 the ends of which are provided with interdigitating projections 6-11 forming in the core a zig-zag pattern of butt-joints such that no two joints in adjacent projections lie in the same transverse plane, and the core parts are separable, without dismantling either part, and capable of reassembly round a coil or coils. Adjacent laminations may overlap by a minimum of twice a lamination thickness, but preferably four times that thickness. The core may be made in the following steps:  (1) A sheet of, e.g: grain-oriented magnetic material, non-oriented steel, or nickel-iron, is formed into a coil (Fig. 3, not shown); and (2) is severed longitudinally along a diameter (Fig. 4, not shown) to produce two sets of semicircular laminations which are then (3) separated magnetically; and (4) individually re-constructed, to form staggered joints, about an insulating mandrel about which a magnetic field is provided to hold the laminations together (Fig. 6, not shown). (5) The resulting preform is then pressed to its substantially rectangular shape. The ends of the laminations may be coated with plastics, and the two core halves assembled while the coating is wet or after drying. Alternatively, a varnish, lacquer, paint, cold- or thermo-setting, e.g. epoxy, resin may be used, and may bond the core parts together; Oil may be used as a lubricant in assembling the parts. The parts may be made rigid by applying a bonding material to their sides, and in this the lubricant may be a silicon-based resin or plastics. The parts may be annealed during some operations, or heated during assembly.

Abstract: 1321158 Rear-view vehicle mirror DAIMLER-BENZ AG 23 July 1971 [27 July 1970] 34731/71 Heading B7J A remotely adjustable and rearwardly foldable external rear-view vehicle mirror comprises a housing in which there is mounted a reflector support adjustable by an operating lever connected to the support and projecting so that it can extend into the interior of the vehicle, the housing being attached to the vehicle by means of a hinge. In order to enable folding of the mirror to occur in the event of an accident the axis of the hinge is arranged to be approximately at right-angles to the direction of travel and approximately parallel to the adjacent outside wall of the vehicle. In a first embodiment, Figs. 1 and 2 the reflector support 4 mounted inside the housing 1 has a bell-shaped sleeve 14 which bears on a shoulder 15 on the pivot 16 of the hinge 2, the sleeve 14 being enclosed by a similar sleeve 17 which is rigidly connected to the operating lever 13. By means of a detent 18 the two sleeves 14, 17 are connected together in the normal working position enabling the position of the support 4 and thus a reflector glass 3 mounted on the support to be adjusted by means of the lever 13, see Fig. 2. Because the support adjusting means and hinge 2 have the same axis, the mirror can readily fold back in the event of an accident, a bent portion 22 being provided in the lever 13 to accommodate the adjacent edge of the reflector glass 3 when in the folded position. In a second embodiment, Fig. 6, the support 28 is mounted in the housing 23 by means of a ball and cup 29, 30 and adjustment of the support and reflector glass 27 attached to it is effected by means of levers and arm 34, 35, 36 connected to the operating lever 32, linkage pivot 39 being substantially in the axis of the hinge 24 to enable folding of the mirror to occur. In both embodiments, all parts outside the vehicle are located inside a hood, 5, Fig. 2, or 40, Fig. 6, which may be of elastic material, preferably rubber, or may be a rigid cover (43), Fig. 8 (not shown), which folds back with the mirror or breaks at a deliberate weak fracture point.

Patent GB-1010063-A (GB)
Title: Method of preparing semi-conducting substances
IPC: C30B25/02
Filed: 1961-09-28
Abstract: Semi-conducting substances comprising two or more components are produced by introducing into a reaction vessel at least one of the component elements in the form of an alkyl compound thereof and the other component element(s) in elemental form or in the form of alkyl or halide compound(s) thereof, and thereafter thermally decomposing the alkyl compound(s) and, if used, the halide compound(s) so as to form the desired semiconducting substance; the quantities of said alkyl compound(s) and, when used, element(s) and/or halide compound(s) employed corresponding substantially to the stoichiometric requirements of the desired semi-conducting substance. Doping of the semi-conducting substances may be effected by introducing at least one doping substance as an alkyl or halide compound or in elemental form into the reaction vessel prior to the thermal decomposition.  The process is particularly suitable for the preparation of semi-conductors of the AIII, BV type, of solid solutions or ternary simulations thereof, or of solid solutions of AIII, BV compounds end their ternary simulations with homogeneous or non-homogeneous doping. (AIII is an element of the third group and BV is an element of the fifth group of the periodic system of elements.) In one embodiment of the invention the semi-conducting substance is obtained in crystalline form by the thermal decomposition of a gas phase mixture of the component compounds, which mixture may be derived from a liquid mixture on heating.  In a second embodiment the semi-conducting substance is obtained in powder form when the compounds introduced into the reaction vessel are thermally decomposed at temperatures below their boiling points under normal pressure by introducing at least one of the compounds in the liquid phase and passing the other compound(s), if any, in the gaseous phase into said liquid phase, the resultant system thereafter being heated to thermally decompose the most stable compound.  Examples are given of the preparation of gallium-, indium-, and aluminium-antimonide; gallium phosphide; zinc oxide; bismuth telluride and zinc-doped gallium antimonide.  Specifications 719,873, 806,923 and 933,211 are referred to.  Reference has been directed by the Comptroller to Specification 809,250.

Title: Improvements in or relating to colour television receivers
Inventor: TOWNSEND GEORGE BORIS
IPC: H04N9/73
Filed: 1958-10-31
Abstract: 875,876. Colour television. GENERAL ELECTRIC CO. Ltd. Oct. 5, 1959 [Oct. 31, 1958], No. 35009/58. Class 40(3) In a colour television receiver a first voltage of magtude proportional to the luminance signal is derived in circuits 13 abd 14 by gating out and smoothing the line synchronizing pulses and a second voltage of magnitude proportional to the chrominance signal(s) is derived in circuits 15 and 16 by gating out and smoothing the subcarrier synchronizing "bursts", the voltages being respectively applied, with opposite polarities, between a common point (earth) and the two ends of a potentiometer 17 and the resulting voltage which appears between the common point and a tapping on the potentiometer being employed as a gain control potential to maintain constant the ratio of the levels of the luminance and chrominance signals. This may be effected as illustrated by controlling the gain of an amplifier 8 in the chrominance channel. Alternatively the gain of the luminance channel may be controlled instead of or in addition to that of the chrominance channel. The position of the tapping on potentiometer 17 is selected in accordance with the desired ratio of luminance to chrominance and may be made manually adjustable to permit adjustment of saturation. The first voltage is also applied in a conventional manner as an automatic gain-control voltage to the radio-frequency and intermediate-frequency stages, the gain of which is also made manually adjustable for control of contrast.

Abstract: 399,676. Drafting patterns for wearing-apparel. ASHE, J. M., 2, Beaumont Street, Sandringham, Victoria, Australia. Dec. 12, 1932, No. 35145. Convention date, Jan. 29. [Class 141.] Pattern sections for drafting the patterns for cutting costumes, coats, dresses, and the like comprise a series of charts with measurement markings and holes, the sections for the front and back of a coat having pivotal points near the waist line. As shown, the sections for a coat comprise a half front section B, Fig. 2, a corresponding back section A, Fig. 1, an under arm section C, Fig. 3, and a combined sleeve and collar sections D, Fig. 4. Pivotal points L are provided for the sections A, B. Bust measurements H<2> .. H<7> are provided with holes for marking through to a paper pattern arranged below, and with terminal markings H<1> also corresponding to bust measurements. Terminal markings E on a line G correspond to measurements taken 6 inches below the natural waist line. The under arm section C contains markings corresponding to bust measurements, and also has a waist line I and a line G which correspond to similar lines on the other chart. Various shaped collar. sections P<1> are incorporated in the chart D. In forming the paper pattern shown in Fig. 10, a pencil line is drawn about 3 inches from the edge of the paper, thereby forming a section Z<2> for determining the size of the lapels. The coat front chart B is placed on the paper, with the pivot point L on the pencil line, and the chart is rotated until the marking H', corresponding to the particular bust measurements, lies on the pencil line. Points corresponding to bust measurements H<2> .. H<7> are marked on the paper, only one of two shoulder lines shown at H<4> being employed. The chart is again pivoted until the line K lies along the pencil line and a marking is made at E. After the chart is removed, the marked points are linked up, using the bottom G of the chart for the contour of the hip, and the upper part of the chart for linking the points on the lines H<2> .. H<7>. The line Z is used for joining the point on line H<6> to the point on the line E. Points Y are also marked and joined by means of line Z. Thereby a section X is formed which with a corresponding section made from the chart A is cut off and replaced by the under arm section C. To prevent wear, the holes for marking are in the form of reinforced eyelets.

Title: Improvements in and relating to filled and sealed packages, and a method of making such packages
Inventor: GREENER FRANK WALTER GEORGE
IPC: B65D5/06
Filed: 1965-08-18
Abstract: 1,097,191. Packages. TEPAR A.G. Aug. 18, 1965, No. 35452/65. Headings B8C and B8P. A filled plastics bag 2, Fig. 2, is attached at 14 to an outer cardboard carton 1. The inner bag 2 is formed from an inflated, extruded tube 20, Fig. 5, closed at its leading end 17 and filled through a nozzle 19 during extrusion. The partially filled tube 20 is gradually lowered into the carton 1 and when completely lowered in additional filling material is supplied so that its walls are pressed against the inner wall of the carton. Before or simultaneously with this final filling operation the zone 14 is heated so that, when the tube 20 is pressed against it, the tube melts and adheres to it. If the zone 14 is heated before the tube 20 is completely lowered into the carton 1, a screen is arranged over the zone to prevent contact between it and the tube wall until the tube is completely inserted. This heating may be by hot air blown or by heated jaws. As an alternative to direct adhesion, a layer of heat activated glue may be provided on the carton 1 in the area of the zone 14. In order to ensure good contact between the zone 14 and the tube, the interior of the tube may be kept above atmospheric pressure. The composite filled container is then closed, Figs. 7, 8 (not shown), the extruded tube 20, extending above the mouth of the partially closed container, being sealed at 17 and cut off through the seal. The seal may alternatively be made through the margins 5. The extended fin, comprising the marginal edges 5 and the protruding tube seal, is folded down flat and secured by gluing or heat sealing to the carton. For the latter, the outer surface of the carton is polyethylene coated. The package is opened by tearing along a perforated or cut line 15 and opening the closure, Fig. 10 (not shown), to form a pouring spout (22). A score line 23, Fig. 9 (not shown), may also be provided in each end panel 6 to facilitate spout formation. The package is suitable for use in the packing of sterilized products, because, by sterilizing the extrusion nozzle and the filling spout 19, the interior of the tube 20 may be kept sterilized as it is never in communication with the atmosphere.
