Abstract: 1,113,263. Transformers and inductors. COMPAGNIE GENERALE D'ELECTRICITE. 2 July, 1965 [8 July, 1964], No. 28241/65. Heading HIT. A transformer or inductor (Fig. 3) has one or more windings 2, 3 each arranged either as a layer winding 2 shaped to correspond to the (curved) shape of the magnetic field which would be produced by the winding in its own vicinity in air or as a disc-type winding shaped to intercept orthogonally the magnetic field it would produce in air as described in Specification 1.085,708 or both (as 3). In either case the windings surround a magnetic core member 1 shaped to correspond to the shape of the magnetic field which the windings would produce in air in the space to be occupied by the core surface. The disc coils forming a L.T. winding may be connected in parallel. The curved layer windings 7 (Fig. 4) are wound on curved formers 8 and held by insulating supports 10. The insulating supports 10 are held in place, against the forces produced by currents in the winding by strut members supported on the outer frame 17. Disc-type windings 6 of the required shape may be used as strut members. A two-part H.T. winding of normal layer or disc type with the parts connected in parallel at their adjacent ends may be used (Fig. 7, not shown). The windings may be of superconductive type as described in Specification 1,084.529. The curve shape of the core limb may be obtained approximately by adding packets of annular laminations at the core and tapering the adjacent portions of the various return members (Fig. 5, not shown).

Title: Improvements in the manufacture of silicon semi-conductor devices by diffusion techniques
Inventor: SCHIMMER RIGOBERT
IPC: H01L21/00
Filed: 1965-07-05
Abstract: 1,036,430. Semi-conductor devices. LICENTIA PATENT - VERWALTUNGS G.m.b.H. July 5, 1965, No. 28384/65. Heading H1K. In the formation of a diffused PN junction in a silicon body the body is heated to a temperature in the region of 1200 C. and the dopant diffused in together with sodium or cobalt. The inclusion of sodium or cobalt leads to a consistent and less than usually degraded minority carrier lifetime in the diffused region. The junction formed has a sharp breakdown characteristic which is maintained even when a gold or gold-contaiping contact material is alloyed at high temperature to the diffused region. The sodium or cobalt may be applied to the surface of the body by evaporation or electrophoresis, but are preferably applied as a solution of a sodium or cobalt salt in a volatile organic solvent or in an etchant. Combinations of the preferred methods may be used. When the salts are applied in organic solvents, the surface of the body may first be lapped to increase its roughness-this gives an increased resultant minority carrier lifetime. Preferred salts are cobalt nitrate, cobalt chloride, sodium sulphate, and sodium chloride. Typical solutions include cobalt nitrate in methanol or isopropanol, sodium sulphate in methanol, cobalt nitrate or sodium chloride in aqua regia. The process is useful for forming PN junctions by the co-diffusion of cobalt and gallim and in the production of three-electrode, four-layer and five-layer controlled rectifiers.

Title: Improvements in or relating to apparatus for reducing sound energy in a fluid medium
IPC: G10K11/172
Filed: 1952-11-11
Abstract: 721,859. Silencing gaseous &c. currents. BOLT BERANEK & NEWMAN, Inc. Nov. 11, 1952, No. 28415/52. Class 7 (2). The sound energy of a fluid medium, e.g. air, is reduced in apparatus, such as a silencer for an automobile or a conduit for an air-conditioning system, provided with one or more zig-zag paths, e.g. sinusoidal in form, the walls of which are adapted to absorb the high frequencies and some of the intermediate frequencies of the sound energy of the band of frequencies in the flowing medium. The intermediate frequencies are further attentuated by making the height W of the crests 13 of the path or paths correspond substantially to the quarter or half-wave length of the mean frequency of the intermediate frequencies so that the intermediate frequencies are resonated within the walls of the path or paths. The crests 13 of each path may be spaced apart longitudinally by a distance corresponding substantially to the half-wave length of the mean frequency of the intermediate frequencies so that the intermediate frequencies are also resonated between the crests of each path. As shown in Fig. 1 the apparatus comprises an aerodynamic test chamber 1 at each end of which is a terminal section 9 provided with a number of sound-absorbing devices 11, e.g. formed of fibre glass, rock-wool or packed felt, shaped to provide longitudinally extending and transversely spaced zig-zag paths. The transverse dimensions of the devices 11 may vary gradually and periodically so that the crest 13 of one device is substantially opposite the valley of the adjacent device, and the paths, successively diverge and converge from and toward one another ; alternatively, the paths may be parallel, Fig. 2 (not shown). The sound-absorbing devices 11 may be of a density (a) which is uniform, Fig. 7 (not shown), (b) which decreases inwardly, Fig. 9 (not shown), (c) which increases and then decreases inwardly, Fig. 10 (not shown), (d) which decreases and then increases inwardly, Fig. 11 (not shown), or (e) may comprise an outer section 16 of least density and intermediate and central sections 18, 20 of successively increasing density, Fig. 8.

Abstract: 758,371. Generating combustion products under pressure. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 15, 1953 [Oct. 15, 1952], No. 28467/53. Divided out of 758,345. Class 51(1). In combustion apparatus which comprises a duct 1 through which flows a fast-moving stream of air (or other combustion-supporting gas), a flame stabilising baffle 3 in the duct forming a sheltered combustion zone, and means 2 for introducing fuel into the duct, an open-ended tube 5 is disposed in the duct extending lengthwise in the combustion region. The upstream end of the tube 5 is disposed just downstream of the baffle and the downstream end is disposed in a region where combustion is substantially complete so that in operation hot gas flows upstream through the tube to the region near the baffle. The baffle 3 in Fig. 1 is of hollow conical shape and fuel is injected in an upstream direction through the injector 2. In a second embodiment, Fig. 3 (not shown), the baffle is annular and of V-section and the tube is also of annular form. In Fig. 5, the baffle 9 is of conical form but the downstream wall 10 thereof is catalytic, the catalyst causing partly-burnt recirculated gas to complete its combustion. The catalytic surface 10 is thermally insulated from the baffle by the layer 11. The catalyst is a refractory material impregnated with platinum or palladium. An open-ended tube 5 is supported downstream of the baffle 9. In Fig. 7 the baffle 12 is of hollow conical form and the downstream wall 13 is perforated or porous, the baffle being connected by a duct 14 to suction so that the layer of gas adjacent the wall 13 may be sucked away.

Abstract: 982,504. Process for producing elements of reconstituted stone. C. G. L. DUSSEL. July 18, 1963 [July 19, 1962], No. 28501/63. Heading B5A. In a process for producing an element of reconstituted stone, a charge of material comprising stone powder, e.g. marble, and an unpolymerized mixture of thermosetting resins is cold-kneaded until a bound paste is obtained, the paste then being poured into a mould which is heated in a press until the resins are polymerized, whence the element is removed from the mould. In order to get coloured markings which give the finished element a more natural appearance, mixes of the colours are spread upon the base of the mould prior to the charging of the mix. In producing such an element the stone powders and resins may be first moulded on an auxiliary support placed above a mould, and then finished in the mould which may be of such a design as to mould tiles having tongues and grooves, or tenons and matrices so that individual tiles can ultimately be connected with one another. The moulds used for producing elements by the above process have movable walls to give different tile thicknesses, the walls being coated with a substance such as oil or wax to prevent the tile sticking thereto, and they may also be vented.

Title: Improved semi-conductor logic units and networks composed thereof
IPC: H03K3/037
Filed: 1957-09-11
Abstract: 845,371. Transistor logical switching circuits. BURROUGHS CORPORATION. Sept. 11, 1957 [Sept. 28, 1956], No. 28687/57. Class 40(6). In a circuit employing a transistor with one electrode connected to a reference potential, a number of inputs are applied to the control electrode over terminals 58a-58e, the output being taken from the third electrode, connected over a resistor to the supply - Vcc. The transistor is maintained in a first state of conduction with signals of only the first of two possible values applied to the input to produce a first output potential, while the appearance at one or more of the input terminals 58a of an input having the second value causes the state of conduction of the transistor to change and provide a second output potential. Assuming the transistors 84, 86 to be fully conducting, the potentials at their collectors are near earth with the result that the base supply potential V b  is sufficient to bias off transistor 72 over the resistors 92, 94a, 94b. If transistor 84 is switched off, the collector potential falls to near that of the collector supply- V cc  and the potential of the input terminal 58a falls to carry the base potential of transistor 72 sufficiently negative for it to conduct and the output potential rises to near earth. Since transistor 72 is fully conducting, the change in conduction of any further transistors such as 86 causes no further change. The output of transistor 72 may be applied to a series of further circuits 52, 54 and 56 the resistor 108 being the equivalent of the input resistance of two further circuits when each unit is designed to feed five further units. Alternatively, resistor 108 may be omitted and the unconnected resistors of the further units earthed. In a modification, Fig. 9 (not shown) the resistors may be transferred from the input to the output electrode. An exclusive or gate may be produced, Fig. 11 in which the units 160, 162, 164, 166 and 168 are all of the form shown in each unit of Fig. 3. Assuming signals A and B to be applied to terminals 170, 172 respectively, the units 162, 164 operate as inverters to provide B, A so that the outputs from units 160 and 166 are, respectively, A x B and A x B and these outputs are applied to the unit 168 which gives as its output #AB + A,#B as required. Two-stable state circuits. A pair of units may be cross-connected to provide a two-stable state circuit, Fig. 10 (not shown).
