Title: Improvements in or relating to semiconductor devices
IPC: H01L29/94
Filed: 1966-02-08
Abstract: 1,135,555. Semi-conductor devices. SIEMENS A.G. 8 Feb., 1966 [9 Feb., 1965], No. 5386/66. Heading H1K. To eliminate capacitative coupling between one region of a semi-conductor device and a conducting layer (in particular a layer connected to another region of the device), which layer is separated from the one region by an insulating layer, the one region is provided with screening zone of opposite conductivity type to the bulk of the region. This screening zone is located immediately under the insulant and is contacted so that in use it may be connected to an appropriate reference potential source. The Specification explains with reference to Figs. 1 to 4 (not shown) that the mere presence of the screening zone greatly reduces the capacitance between the region and the overlying conductor and that by maintaining the potential of this zone constant the capacitance is effectively eliminated in use. The structure of Fig. 5 is a planar transistor in which the contacts 12, 13 to the base and emitter regions 17, 18 respectively are extended over the portions 14 and 16 of a surface oxide layer 10. The capacitance between the base contact 12 and the collector region 9 is eliminated in use by applying a suitable potential to a screening zone 19 of opposite conductivity type to region 9 by way of contact 11. A second screening zone 20 may also be provided to permit elimination of capacitance between the collector region 9 and the emitter contact 13. This second screening zone may be contacted or uncontacted. In use the contact to either or both screening zones may be connected to any convenient reference potential source, but if the transistor has a terminal which is normally grounded in use then the appropriate screening zone contact may be permanently connected to this terminal. Fig. 6 (not shown) depicts such an arrangement, in which the transistor of Fig. 5 has the contacts 11 and 13 permanently interconnected so that in grounded emitter operation the screening zone 19 will also necessarily be grounded. Reference has been directed by the Comptroller to Specification 1,007,936.

Title: Filament forming apparatus
IPC: H01K3/04
Filed: 1962-02-13
Abstract: 943,523. Bending coiled filament wire. SYLVANIA ELECTRIC PRODUCTS Inc. Feb. 13, 1962 [Feb. 13, 1961], No. 5515/62. Heading B3E. Apparatus for shaping a length of coiled filament wire into a filament having a plurality of segments comprises a coil holder, a parting knife adapted to enter the gap between two adjacent turns of a coil held in the holder and a bending knife extending in a direction transverse to the axis of the unbent coil and adapted firstly to enter the aforesaid gap or another gap close thereto and then to twist about the said direction so as to form a bend in the coil at the junction of the two filament segments. A coil 1 to be bent is placed across the projecting upturned finger of a coil holder 36. A parting member 37 is then slid forward in the holder 36 by a cam operated lever 64 whose lost motion pin 214, Fig. 4A, and slot connection with a clamp member 212 allows a spring 208 to move the clamp 212 forward and hold the coil 1 against the upturned finger of the holder 36. The parting member 37 continues to move forward until it is located between adjacent turns of the coil 1, Fig. 13. Meanwhile a slide 72, carrying a bending member 70, is moved up a guide 102 to a working position by a cam-operated link 90. The coil holder 36, which is pivoted at 38 to a block 34 on a slide 32, is then raised slightly to a working plane, by lifting the slide 32 by a cam-operated lever 48. The slide 32 also moves a pivoted arm 58 carrying a plate 62 which damps whipping action of the coil 1 as it is bent. The bending member 70 then moves into position between turns of the coil adjacent to the turns between which the parting member 37 was inserted. This is effected by sliding a block 88, which carries the guide 102, horizontally along a fixed guide 92 by cam operated link means 94, 100. The member 70 is then moved away slightly from the member 37 to stretch the coil turn therebetween, Fig. 14, by sliding the guide 102 transversely on the block 88 by a bellcrank 106 rocked by a cam-operated link 108. The bending member 70 is then rotated 180 degrees, to bend the coil as shown in Fig. 16, by a rack on a member 76 which engages a pinion on the member 70, the member 76 being moved by a lever 80 rocked by a cam-operated link 84. Another coil holder 36 is rocked about its pivot 38 by a cam operated lever 42 and is lowered by the lever 48 so as to move into a position to receive the bent coil 1 from the first holder 36, Figs. 16, 20. Parting and bending members 37, 40 associated with the second holder 36 then effect another bend in the coil 1 and the first holder 36 is withdrawn. After several operating cycles of both sets of members 36, 37, 70 a plurality of coil segments will have been formed, Fig. 22. Cam shafts are automatically stopped on completion of the desired number of bends. A blast of air may remove the bent coil from its holder. The bending member 70 and parting member 37 may be inserted together between the same coil turns. Specification 676,266 and U.S.A. Specification 1,726,480 are referred to.

Patent GB-491021-A (GB)
Title: Improvements in the manufacture of artificial textile materials
IPC: D06M13/165
Filed: 1937-02-24
Abstract: Artificial silk fabrics of improved extensibility are obtained by shrinking fabrics containing superficially saponified yarns of cellulose organic esters with aqueous solutions of organic liquids having a solvent or swelling action on the organic esters. Caustic soda or potash, or sodium carbonate, may be used as saponifying agent.  In the case of cellulose acetate yarns, the superficial saponification may be such that the average acetyl value is reduced to 1,8-2,1 acetyl groups per cellulose unit. Saponification of the yarn may be effected either before or after the formation of the fabric.  Acetone, dioxane, or ethylene methylene ether, may be used as shrinking agent.  In an example, cellulose acetate cr<\>epe-de-chine fabric is scoured and then superficially saponified by treatment at raised temperature with a one per cent solution of sodium carbonate.  The fabric is dyed, dried, and then shrunk by padding it through an aqueous solution of acetone.  One dip and one squeeze are given and the fabric is then fed to a pin-stenter for drying.  The stenter is run at a slower speed than that of the fabric through the mangle so as to allow shrinkage to take place.  In another example, the fabric is carried through the shrinking medium by an endless calico band and on emerging from the solution it is passed into another bath where it is washed with water.  The fabric is then slack dried on an endless band conveyer.

Title: Improvements in or relating to colour television receivers
IPC: H04N9/455
Filed: 1964-02-11
Abstract: 1,035,723. Colour television receivers. GENERAL ELECTRIC CO. Ltd., and J. J. JAROSY. Feb. 10, 1965 [Feb. 11, 1964], No. 5677/64. Heading H4F. In a colour television receiver for use in an N.T.S.C. type of system the colour synchronizing " burst " signal, which appears on the back porch immediately following the line synchronizing signal, is separated from the received television signal, which is applied to a synchronizing pulse separator circuit 2 and a gating circuit (not shown), by applying a control signal developed from separated line synchronizing pulses and passed via an integrating circuit 13, 14 to open the gating circuit during the " burst " interval. The receiver employs a flywheel line synchronization arrangement incorporating a balanced phase detector 1 and the separated line synchronizing signals developed in the anode of pentode 2 are fed to the phase detector via an auto-transformer 3. In operation in response to the line synchronizing pulses two signals of the same waveform and opposite polarity appear at the ends of winding 4 each being a distorted version of the corresponding line synchronizing pulse with the portion of the signal between the peaks occurring during reception of a colour " burst " signal. The first excursion is negativegoing and hence the integrated signal at the grid of triode 15 consists of a negative-going pulse occurring during the reception of a colour synchronizing " burst " signal. The triode is biased so that in response to each pulse at its grid there appears at its anode a positive-going pulse of substantially rectangular waveform which is applied via a capacitor 16 to the gating circuit.

Filed: 1949-03-02
Abstract: 660,689. Inductances. RADIO CORPORATION OF AMERICA. March 2, 1949 [March 23, 1948], No. 5736/49. Class 38 (ii). A core for tuning the resonant circuits of radio receivers or the like comprises a magnetically permeable core element and at least one short-circuited coil element, the elements being mechanically coupled in series in an axial direction in such a manner that they are, as a unit, displaceable together in relation to the inductance coil of the resonant circuit, the distance between the magnetically permeable core element and the adjacent short-circuited coil element being approximately half the length of the inductance coil. An inductance coil 1, which may form part of the tuned circuit in either the aerial or the local oscillator circuit of a super-heterodyne radio receiver, is tuned by a core assembly 2 comprising an insulating rod 7 carrying a magnetic core element 4 and non-magnetic, electrically conductive elements 5, 6 which may be short-circuited coils, copper rings or discs, or the like, the distance between the magnetic element 4 and the element 5 being approximately half the length occupied by the coil 1. The insulating body 8 on the rod 7 forms a bearing for the core assembly. Movement of the core assembly through the coil 1 will alter the coil inductance and hence the resonant frequency of the tuned circuit, the variation in. frequency due to the movement of the elements 4, 5, 6 being shown in Fig. 2. The dotted curves 11, 12, 13 represent the relation between the tuned frequency and the movement of the elements 4, 5, 6, respectively if each existed separately, the additive effect of all three elements being indicated by the full line curve 14. Thus, in a short-wave radio receiver, the frequency bands devoted to public services will be traversed more slowly than the unwanted intermediate frequency bands so facilitating the tuning operation. The relative positions of the core elements determine the ultimate shape of the curve 14 and the position of the elements may also be relatively adjustable to allow adjustment of the frequency range coverage. According to another embodiment further elements similar to the elements 5, 6 may be included in the core assembly to extend the tuning range.
