Title: Flow control valve for hydraulic jack system
IPC: F16K31/363
Filed: 1958-08-15
Abstract: 844,123. Hydraulic apparatus. CATERPILLAR TRACTOR CO. Aug. 15, 1958 [June 9, 1958], No. 26276/58. Class 69 (2). A flow control valve for use in an hydraulic system, such as may control an implement drawn or carried by a tractor, comprises restrictions 18 in passages 11, 12 adapted to be included one in each of two conduits which may be connected selectively to pressure and exhaust, valves 20, 21 normally closing ports 24, 25 leading one from each passage to the other, and means 29 to communicate pressure in whichever passage is connected to the inlet conduit to open it and admit fluid to the other passage. The valves are urged to positions clsiong the ports by springs 26, 27 and the pressure built up by the restriction in whichever of the passages is connected by the inlet conduit to the end of a double-acting hydraulic motor is transmitted to the end of the corresponding valve by means of the passage 29 to move the valve and open the port, passageways 30 or 31 preventing back-pressure restricting the movement of the valve. The excess pressure in the inlet conduit is thus connected to the exhaust conduit and the flow of fluid to the motor limited to ensure regulated movement thereof.

Title: Method of making a layer containing a fluorescent material
IPC: G21K4/00
Filed: 1931-09-21
Abstract: 380,256. Fluorescent screens. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Sept. 21, 1931, No. 26355. Convention date, Sept. 27, 1930. [Class 98 (i).] A screen, e.g. for X-ray work, is formed by volatilizing fluorescent material and precipitating it upon a support in a vacuum. The support may be enclosed in a glass bulb together with one or more wires coated with a fluorescent material such as zinc sulphide or calcium tungstate, the ends of the wires being brought out through the walls of the bulb. After exhausting the bulb, the fluorescent material is volatilized and precipitated by passing an electric current through the wires. The support may be previously coated with a material which adsorbs the fluorescent material, such as calcium fluoride in the case of fluoresceine, and the fluorescent layer may contain more than one fluorescent material. Thin transparent layers are readily obtained by the method. The grain-size of the layer may be controlled by varying the speed of volatilization ; a high speed yields a layer of fine grain. The Specification as open to inspection under Sect. 91 (3) (a) states also that the fluorescent layer may contain other materials which may be volatilized and precipitated at the same time as the fluorescent material. This subjectmatter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 361,388.

Abstract: 1,172,664. Chlorosulphonating polyethylene. E.I. DU PONT DE NEMOURS & CO. 4 June, 1968 [5 June, 1967; 7 May, 1968], No. 26622/68. Heading C3P. Polyethylene is continuously chlorosulphonated and chlorinated in an elongated reaction zone in which both liquid and gas phases exist by a process wherein a solution of polyethylene in an inert solvent, sulphuryl chloride and a free radical initiator are fed into one end of the reaction zone and at least 0.08 part, per part by weight of sulphuryl chloride, of chlorine is introduced near the other end, the pressure being such as to allow the escape of hydrogen chloride and sulphur dioxide from the liquid phase in the form of gas bubbles. Reaction may be effected in the presence of a catalyst, e.g. a tertiary amine, and further chlorine may be introduced and off gas removed from the reaction zone at intermediate points. Apparatus suitable for carrying out the process is described and illustrated, and examples describe the reaction of polyethylene dissolved in carbon tetrachloride and optionally chloroform, with chlorine and sulphuryl chloride in the presence of pyridine, polydimethylsiloxane and azodiisobutyronitrile, azodicyclohexane carbonitrile.

Title: Character recognition systems
IPC: G06V30/182
Filed: 1971-04-19
Abstract: 1306798 Character recognition SIEMENS AG 19 April 1971 [10 April 1970] 26710/71 Heading G4R In a character recognition system the character is scanned in successive vertical sweeps, the image signals from adjacent columns being employed to develop a signal which is a complete description of a contour of the character. A contour is a part of the outline of the character: Fig. 1 shows six contours obtained by scanning numeral 2. When a black-white or white-black transition is detected in the output of the scanner the height at which the transition occurs, i.e. the yordinate, is passed as a signal Yn(k) to a first store. This transition indicates the presence of a contour in a column n. Successive transitions (contours) in each respective scan column are given an ordinal number k, the first transition in each column having k = 1. The first store feeds a second store, such that the second store contains the y-ordinates Ym(k) of the transitions which occurred in the previous scan column m. Both stores feed circuits which, by examination of the values of the y-ordinates of adjacent contours in a column n and of ajdacent contours in the prior column m, determine whether a transition under consideration represents the start or end of a contour, or represents the continuation of a contour which was detected during an earlier examination. In the latter case the difference between successive y-ordinates of the same contour provide elementary feature signals indicative of the slope and the magnitude of the slope. The outputs of the circuits together with the scan x-ordinate are. stored in a third store having a number of storage rows. The k-th row stores the complete description, up to the present scan instant, of the k-th contour. If a transition is found to represent the start of a contour the ordinal number (k-1) of this contour will, in general, be the same as that allocated in the previous column to a contour having a greater y-ordinate, e.g. see Fig. 2. In order that the contuour signals may be correctly stored (i.e. the k-th contour in the k-th row) it is therefore necessary to remove from their present addresses (row) the stored signals which represent those contours, e.g. (k-1) which now lie above the new contour (k) and to replace them two rows above their present positions, e.g. at (k+1). When the end of a contour is detected the corresponding row of the third store is read out, providing a complete description of the contour to a fourth store. As this leaves a gap in the third store the contour descriptions lying above the gap are read in to rows two lower than their existing rows. To ensure correct operation of the y-ordinate examining circuits the character must lie between upper and lower reference contours.

Abstract: 1,091,813. Impulse transmitters. GENERAL ELECTRIC CO. Ltd. Sept. 8, 1965 [June 29, 1964], No. 26785/64. Heading H4K. In a key-operated impulse transmitter in which telephone number digits are successively stored in a mechanical store and transmission of digit impulses to line begins as soon as the first digit is stored, the mechanical store comprises a cylinder 8 having projecting resilient contacts 7 arranged in rows of ten contacts, each row running the length of the cylinder and all rows angularly spaced around the cylinder so that a row corresponds to a digit position and corresponding contacts of each row correspond to the digit value. All contacts in a row are electrically connected to one of ten stop rings 9 mounted on the cylinder. Ten semi-circular arcs are spaced along the cylinder adjacent the corresponding contacts of each row, so that as a key is depressed the associated one of the ten contacts of a particular row is deflected by the wedger 28 and due to the simultaneous incremental rotation of the cylinder this contact passes to and engages the other side of the arc, so storing the value of the digit. The contact travels round the arc as the cylinder rotates for successive storing of the digits. After keying up the first digit a rotary switch begins to supply potential to each stop ring and so each row, in turn which potential is extended via one of the ten arcs to one of ten terminals of a pulse generator to supply the appropriate number of digit pulses. In another arrangement (Fig. 4) one or two out of four terminals of a pulse generator receive a potential to cause it to transmit a particular number of digit pulses so that the cylinder has only five contacts per row and connected in a group of three and a group of two. The individual contacts 56 are modified in that they have a bent-over portion at the end and, when deflected by the right-handed sideways movement of the rod 96 as the result of key-operation, they pass under and make contact with the under-surface of the arc 52. Otherwise the contacts pass freely over the top. Each key is associated with one or two rods to deflect contacts of the two groups. In this second arrangement the pulse generator is enabled by a pair of cam-operated contacts 107 (Fig. 7, not shown); the cam being stepped away leaving them operated by one increment for each key depressed but stepped back again as successive rows of contacts are reached by the rotary switch. The cam can be stepped back to its home position by pulses with simultaneous inhibition of the digit pulse generator upon the operation of a cancel key.
