Patent GB-225499-A (GB)
Title: Process of recovering the constituent metals of tinplate and tinned articles
IPC: C22B25/06
Filed: 1924-04-12
Abstract: Tin-plate scrap is treated with a bath of hydrochloric acid containing an oxidizing compound of manganese, such as manganates, or permangates, manganic salts, or manganese dioxide, with or without another oxidizing salt.  In an example, manganese dioxide and alkali dichromate are employed, the temperature being 70-90 DEG  C.  The tin may be recovered from the solution by zinc or by electrolysis.  For the electrolysis a carbon anode and a copper, iron, or other suitable cathode are employed, the current being supplied at 6-7 volts.  The tin is deposited in the spongy condition.  The Specification as open to inspection under Sect. 91 (3) (a) includes the use of other oxidizing agents instead of the manganese compound, alkali chromates, and dichromates being mentioned.  This subject-matter does not appear in the Specification as accepted.

Abstract: 184,217. Gribojedoff, N. March 30, 1921. Spray carburettors.-In engines which rotate about their cylinder axes and have fixed rings surrounding the cylinders for controlling the inlet and exhaust ports, axial passages located. above the head of each cylinder are provided for supplying liquid fuel, air for combustion, and lubricating oil. According to the construction shown in Fig. 1, a cylinder 21 rotates about its vertical axis and carries at its lower end a toothed wheel 22 gearing with a pinion 24 secured to a crank shaft 23 having webs 26 shaped as shown in Fig. 1. Fuel is admitted through a passage 41 discharging on to the cylinder head through orifices 36 in a nozzle provided with a perforated baffle 39.

Abstract: 560,091. Electricity supply; transformers. BRITISH THOMSON-HOUSTON CO., Ltd. July 16, 1942, No. 9885. Convention date, July 19, 1941. [Class 38 (iv)] Transformer arrangements for the simultaneous adjustment of the relative magnitude and/or phase of voltages in two circuits 11, 12 comprise two main windings 14, 15 on one core and two interc¾nnected auxiliary windings 16, 17 on a second core, one or both of which are preferably interposed between the main windings, one main winding 15 being common to both circuits and the remaining main winding 14 being in series with one of the circuits only. The auxiliary windings are arranged so that one 16 is included in one of the circuits and the other 17 may be in the other circuit or in the common circuit. Simultaneously operated tap-changing means such as 19, 20 connect the primary winding 18 of the auxiliary transformer to variable portions of the common winding 15 on the main transformer or to a third winding 10 on that transformer, which may be a primary or tertiary winding, so that the voltage.in the auxiliary windings is variable. According to the connections or relative winding directions of the auxiliary windings the relation between 'the voltages of the two circuits 11, 12 may be simultaneously changed in the same or opposite senses. The auxiliary or main windings need not have the same number of turns. The energy source may be connected to a winding on the main transformer or to either of the circuits. The arrangement may be incorporated in a polyphase connection and the excitation of the auxiliary transformer may be arranged to produce opposing changes in phase in the two circuits as well as or instead of voltage changes. The Specification as open to inspection under Sect. 91 described also an arrangement in which the main and auxiliary windings were all on the same core. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the art of making colour-kinescopes
IPC: H01J9/227
Filed: 1951-04-27
Abstract: 702,468. Cathode-ray tubes. RADIO CORPORATION OF AMERICA April 27, 1951 [April 28, 1950], No. 9946/51. Class 39(1) In a cathode-ray tube for colour television in which one or more electron beams scan a threecolour target 5 through an apertured mask, the target has phosphor areas, corresponding to each colour, of the same shape and pattern as the apertures in the mask 4. To realize that pattern on the target, a jig is set up in which a light source corresponds to an electron gun, and a photographic plate to the target. Light directed through the mask on to the photographic plate discloses the required pattern. Instead of light, electrons may be used, the apparatus being mounted in an evacuable chamber. A stencil is then prepared from the photographic plate, and is used either in a settling process, or in a silk screen printing process to form the required phosphor pattern on the target. By movement of the stencil to each of three positions in turn, the three patterns corresponding to the three colours are laid down. The target is then mounted in place of the photographic plate on the back of the frame on which the mask is mounted. Centring masks on the mask and target, photographically recorded, serve as an aid in positioning the target on the frame. The correct position is tested by observing the pattern of light passing through the mask. The mask is mounted on the metal frame so as to be taut. This is effected by clamping the mask to the frame and expanding it by heating. In clamping the glass target to the metal frame holes are provided to allow for differential expansion when, in sealing and evacuating the cathode-ray tube, the frame and other metal parts are heated. The frame supported mask and target assembly 4-5, is then transferred to a smaller jig 52 by which the assembly is mounted in the cathode-ray tube. After orientating the electron gun, or battery of guns 1, 2, 3 at the precise angle or angles required with the aid of an auxiliary jig 59 the correct orientation is recorded by making reference lines 65 on one of the gun barrels, and on the neck of the tube. The tube neck 10 is then removed, and the target assembly fixed in position. The jigs are removed, and the tube neck is then sealed to the tube body 6 in its correct position by use of the reference lines. The conductive coatings 68 on the tube neck and body part are connected across the join by conductive strips extending between the terminals 67, 70 for the coatings.

Abstract: PURPOSE:To obtain a semiconductor device having a stable high-resistance element suitable for the microscopical formation of the dimension of an element by a method wherein the surface of a poly Si layer exposed from an aperture is oxidized, Si ions are implanted in an oxide film to form a high-resistance layer and a high-resistance part is formed in the longitudinal direction. CONSTITUTION:An insulating film 2 is formed on a semiconductor substrate 1 and a wiring layer 3, which is used as a gate electrode and consists of a poly Si film, is formed thereon. After an interlayer film 4 is deposited, a contact hole is opened and the poly Si film in the contact hole is turned into an oxide film 5 in an oxidizing atmosphere. An implantation of Si ions (a) is performed. The Si oxide film 5 has a conductivity and is turned into an Si oxide film 6 containing abundantly Si. A second poly Si film is deposited and a contact hole and a wiring part 7 are formed by doping an impurity. The film 6, that is, a high-resistance layer, is formed on the aperture on the layer 3 in the longitudinal direction. Thereby, a semiconductor device having a stable high-resistance element suitable for the microscopical formation of the dimension of an element is obtained.
