Title: Apparatus for converting between different representations of numbers
IPC: H03M7/12
Filed: 1960-02-01
Abstract: 909,543. Digital electric calculating-apparatus. THOMPSON RAMO WOOLDRIDGE Inc. Feb. 1, 1960 [May 22, 1959], No. 3570/60. Class 106 (1). Conversion of a number from one radix to another is effected by dividing repeatedly by the second radix, successive remainders then expressing the number in the second radix in digits of increasing significance. In the embodiment conversion takes place from pure binary to binary coded decimal. A binary register 118 comprises 11 flip-flops B1-B11, each of which can be set to true or false, i.e. to store 1 or 0, by coincidence gates with inputs designed according to Boolean logic. This logic is dependent on clock pulses C, time signals P1-P14 and the state of the other flip-flops. The binary coded number is entered into B1-B10 and then shifted leftwards, i.e. to a position of greater significance, to occupy B2-B11. Division by ten in binary code takes place at times P1-P7 with shift leftwards at each time signal on the principle of attempted subtraction, each subtraction being accompanied by the entry of 1 into flip-flop B1. At the end of division the remainder is stored in B8-B11 and the quotient in B1-B7. At time P8 the remainder is transferred through the logical network 110 to flip-flops D1-D4 of decimal register 126 where it now represents the least significant decimal digit in binary-decimal code. The quotient is shifted leftwards to form the dividend of another division which requires only four clock pulses P9-P12. The second remainder is shifted to D5-D8 and the quotient to D9-D12 to form the second and third decimal digits.

Title: Improvements in or relating to television systems
IPC: H04N3/32
Filed: 1933-02-07
Abstract: 413,401. Television. BULLIMORE, W. R., and BEDFORD, L. H., Cossor Works, Highbury Grove, London. Feb. 7, 1933, No. 3743. [Class 40 (iii).] In a television system in which the scanning and reconstruction of an image is effected by varying the speed of the scanning spot in accordance with the variations of the light intensity of different parts of the image, means are incorporated for modulating the intensity of the scanning spot at the receiver for the purpose of intensifying the received image. At the darker portions of the picture the scanning spot does not move at the speeds theoretically required to produce the dark portions of the image contrasted correctly with respect to the light portions, and in the arrangements described the intensity of the cathode beam is decreased as the rate of change of the scanning voltage increases. In Fig. 2 the incoming scanning voltage is applied to the grid of a valve V having in its plate circuit an inductance L and a full wave rectifier W; and the voltage produced across a resistance R is proportional to the rate of change of the voltage on the grid of the valve V or to the scanning velocity. The voltage across R is fed through condenser C1 to the grid of a valve V1 in whose plate circuit is a resistance R2 from which a tapping is taken to the modulating electrode of the cathode-ray tube. In an alternative arrangement, Fig. 3, the scanning voltage is applied to the grids of valves V1, V2 operating in paraphase. The plate circuits are connected to the plates PX1, PX2 of the oscillograph and the resistances R1, R2 are joined by an inductance L to which is coupled a centre-tapped inductance L1. The voltages across the two portions of the inductance are applied to the grids of valves V3, V4 forming a balanced rectifier arrangement, and from a tapping on a resistance R34 a voltage proportional to the rate of change of the scanning voltage is applied to the modulating electrode of the cathode ray tube. The voltage applied to the modulating electrode of the cathode-ray tube is independent of the sign of the velocity and the intensity of the cathode beam is reduced during the fly-back at the end of a line or picture. Specifications 396,422 and 399,469 are referred to.

Title: Improvements in or relating to the manufacture of combustible gas
Inventor: SAPIRO REUBEN HILLEL
IPC: C01B3/48
Filed: 1961-02-01
Abstract: A cyclic process for combustible gas comprising plant heating phases alternated with gas-making phases in which solid, liquid, or gaseous fuel is reacted with steam with or without air, and in which the carbon monoxide content is lowered by catalytic conversion with steam to carbon dioxide, after the gas has been partially cooled, and after the removal of dust and any liquids condensed by the cooling, but before removal of sulphur-containing compounds, and before its water vapour content has fallen below one volumetric equivalent of the carbon monoxide present, is characterized by using a catalyst, in the conversion of carbon monoxide, which in the presence of said minimum volumetric ratio of water vapour will hydrogenate oxygen and oxides of nitrogen and deleterious unsaturated hydrocarbons, and whose activity for the hydrogenation and conversion is promoted by the presence in the gas of sulphur-containing compounds.  The cooling may be by direct quenching with water.  The gas may also be passed into a gas holder after cooling and subjected to further cooling before conversion. The catalyst may be molybdenum, nickel, or cobalt oxides maintained at between 400 DEG  and 600 DEG  C.  When the sulphur content of the gas before conversion is less than 100 grains per 100 cu. ft. of gas a second conversion stage using iron oxide catalyst at between 300 DEG  and 450 DEG  C. may be used.  The fuels may be coal, coke, petroleum oil, or refinery gas.

Filed: 1967-01-26
Abstract: 1,174,641. Protective arrangements. ROBERT BOSCH G.m.b.H. 26 Jan., 1967 [26 Jan., 1966], No. 3911/67. Heading H2K. [Also in Division G3] An electrical supply system, e.g. for a motor vehicle, comprises a generator 10 connected to a battery 16 over output lines 14, 15 by way of a rectifier 13 and having a separate rectifier 17 for its field winding 12; a voltage regulator 21 including a transistor 22 which is connected, over normally-open relay contacts 28, in series with the field winding 12 and which controls the field current in dependence upon output voltage variations as detected by a circuit including a voltage divider 46, 47, 48, a reference Zener diode 43 and a control transistor 23; and a protective circuit 24 including a relay coil 29 which is connected over a switch 32 to the output lines 14, 15 and which is shunted by a thyristor 26 the control electrode of which is associated with a further output voltage sensing circuit including a voltage divider 58, 59, 60, a Zener diode 57 and a transistor 25. In normal operation the relay coil 29 is energized so that the contacts 28 are in the closed position as shown and the output voltage is maintained constant at a predetermined value by the action of regulator 21 in known manner. However, if, because of a fault in the regulator, the output voltage should become excessive, e.g. at least 5% higher than the rated value, the Zener diode 57 conducts to render transistor 25 conductive, whereby a signal is applied to the control electrode of thyristor 26 which itself conducts to short-circuit the relay coil 29; the contacts 28 then move to de-energize the field winding 12, so that the generator output falls almost to zero, an indicating light 36 then being energized from the battery 16 over a resistor 35, the contacts 28, the transistor 22 and a resistor 27. The thyristor 26 may be replaced by a transistor (Fig. 2, not shown).

Title: Improvements in or relating to reflex electron discharge devices
IPC: H01J25/24
Filed: 1943-03-10
Abstract: 631,164. Velocity -- modulation tubes. SPERRY GYROSCOPE CO., Inc. March 10, 1943, No. 3930. Convention date, March 24, 1942. [Class 39 (i)] A reflex electron discharge device comprises a resonator 2 means for projecting an electron stream through entrance and exit grids 4 and 5, and a reflector electrode 15, the entrance grid 5 and electrode 15 being simultaneously moved with respect to exit grid 4 for tuning purposes. In the construction shown electrons pass from a cathode 6 through entrance and exit grids 5 and 4 in the walls of the resonator and are then reflected back by plate 15 into the resonator. Tuning is effected by moving the part 3 which is connected to the rest of the resonator by a flexible diaphragm 10. In order to maintain the apparatus under its best operating conditions the plate 15 is moved in conjunction with part 3. This is effected by mounting both members on posts 13 and 17 connected by a plate 18 and subjected to the pull of a spring 23. When a wire 25 is heated by passing a current therethrough it expands and permits the spring 23 to bend the posts 14 and 17 and move the grid 5 and plate 15. Wire 25 can be replaced mechanically by a bimetallic element surrounded by an electric resistance heater. Also rods 14 and 17 may be connected by rods at different effective points in their length to cause a desired ratio to be maintained in the movements of parts 2 and 15. The grids 4 and 5 are arrangements of radial rods which are alternately short and long. The resonator is provided with an output loop 11 and a concentric connection 9. Specifications 535,767, 606,794, 631,166 and 3524/45 (as open to inspection under Sect. 91) are referred to.
Patent GB-566371-A (GB)
Title: Improvements relating to the treatment of fibrous materials of regenerated cellulose
IPC: D07B7/12
Filed: 1941-03-26
Abstract: Textile materials of regenerated cellulose are impregnated with a water-resistant cellulose ester or ether and are also treated with an etherifying or esterifying agent containing a long aliphatic chain under such conditions as to form on the materials an ether or ester of cellulose containing a long aliphatic chain. The treatment may be applied to fibres, filaments, yarns, twines, cords, ropes, or fabrics.  The treatment renders the materials, particularly ropes and cords, more compact.  It increases the wet tenacity, improves the handle and renders the materials substantially waterproof.  The regenerated cellulose materials may be impregnated with the cellulose ester or ether in a non-aqueous medium at an elevated temperature. The impregnated material may be treated with a quaternary ammonium halide in which a long chain alkyl oxymethyl group is attached to the nitrogen atom, and then heated so as to decompose the halide and effect an etherification of the cellulose.  In an example, a rope of regenerated cellulose yarns of high tenacity, obtained by stretching cellulose acetate yarns in steam and then saponifying completely, is impregnated with a hot solution of ethyl cellulose and castor oil in xylene and butanol.  The rope is dried and then immersed in an aqueous solution of octadecyloxymethyl pyridinium chloride containing sodium acetate.  It is dried and then baked. If desired, the treatment may be applied to the fibres, yarns, strands, or cords, before these are made into ropes.  Other softeners may be used, e.g. tricresyl phosphate, dimethyl phthalate, tri-(monochlor butyl) phosphate, olive oil, palm oil, linseed oil, cotton seed oil, or mineral oil.  Instead of ethyl cellulose there may be used propyl, benzyl, or hexyl cellulose or cellulose propionate, stearate, palmitate or laurate.  Other etherifying agents which may be used are oxymethyl pyridinium chloride compounds containing a dodecyl, lauryl, cetyl, or oleyl group, or corresponding compounds containing instead of a pyridine residue, a residue of picoline, quinoline, N-alkyl or benzyl piperidine, a trialkylamine, or dialkyl cyclohexylamine. There may be used octadecyloxymethyl chloride in solution in pyridine. Octadecyl and similar chlorides may be used.  Lauric, myristic, palmitic and stearic anhydrides and chlorides are specified esterifying agents.  Long chain alkyl esters of chlorocarbonic acid or long chain alkyl carbylamines, e.g. stearyl carbylamine, may be used.  The process is applicable to regenerated cellulose materials in admixture with cotton, linen, jute, silk, wool, polyamide, polyvinyl, or other textile materials.  Specification 559,584 is referred to.  The Provisional Specification describes also processes in which other water-resistant polymeric film-forming esters or ethers, e.g. polyvinyl esters or ethers, are used for the impregnation.
