Title: Improved compressed air device for the starting and decompression of multi-cylinder engines
IPC: F01L13/08
Filed: 1959-07-23
Abstract: 876,214. Starting; relieving compression. CESKOSLOVENSKI ZAVODY NAFTOVYCH MOTORU PRAHA, NARODNI PODNIK, and DOROSENKO, N. July 23, 1959 [Aug. 8, 1958], No. 25368/59. Class 7(5). In a compressed air device for starting a multi-cylinder engine and for venting the cylinders of the engine, which cylinders each have a starting valve provided with a compressed air cylinder and piston which is operated by compressed air admitted through an air distributer, the air distributer body is provided with a starting air passage and a decompression air passage, the two passages being connected to each other, for each working cylinder, by means of a bore which is provided with an outlet opening communicating with a pipe intended for the supply of compressed air to the compressed air cylinder on the respective starting valve and in which there is movably mounted a cylindrical valve operable in one direction by the compressed air of the starting device and in the other direction by the compressed air of the decompression device whereby the valve in its end position allows the flow of the control air from one or the other of the passages into the outlet opening but prevents the penetration of the air from one of the passages to the other. As shown the distributer 3 consists of a cylindrical body 10. In the distributer are annular passages 12, 13. On starting the engine the pipeline 6 (Fig. 1) is filled, by opening the valve 4, with compressed air from the reservoir 5. Simultaneously the air penetrates into the annular passage 12 of the distributer 3. The slide valve 16 which does not lie above the cam projection moves into a position in which it allows the passage of compressed air into its corresponding bore 23 where the cylindrical valve 30 slides to the left hand end and thus reblocks the outlet opening 24. The air flows into the tube 2 and into the compressed air cylinder of the starting valve. The starting valve is opened and compressed air flows into the working cylinder. The described operation repeats itself for each individual working cylinder in dependence on the rotation of the cam-shaft 20. For the purpose of an easier adjustment of the cam-shaft during reversing or for an easier turning of the crank-shaft of the engine compressed air is admitted into the annular passage 13 through the pipe 33. Due to the air pressure all the cylinder valves 30 slide to the right and allow inflow of compressed air into the outlet openings 24 and to the pipes 2 whereby the compressed air is led to the compressed air cylinders of the starting valves. This makes possible the opening of the valves and thus the venting of the engine cylinders to the atmosphere.

Title: Improvements in and relating to an accurately centered bearing assembly
IPC: F16C23/08
Filed: 1959-07-24
Abstract: 908,486. Bearings. PITNER, A., and ROULEMENTS A. AIGUILLES SOC. ANON. DES. July 24, 1959 [July 24, 1958; June 8, 1959], No. 25415/59. Class 12 (1). In a bearing comprising an inner race ring 2, an outer race ring 1 and bearing members 3 adapted to roll therebetween, one of the rings is supported by projections . of a housing spaced apart relatively to the axis of the bearing by an angle less than 180 degrees and is deformed by the application of a force F. This force, which may be applied mechanically, pneumatically or hydraulically, eliminates radial play to centre a rotary shaft. The force F may be the resultant of a number of forces or may be produced by the resilience of the race 1, Fig. 3, which has a protrusion 18 on its raceway and is additionally supported at 19, 20. The force F is adjusted by varying the angular distance between the supports 19, 20 and screws 21, 22 therein serve to temporarily deform the race to facilitate the assembly of the bearing. Light forces may be effected by a spring 35, Fig. 7, and the tension may be adjusted by a screw or cam. Conveniently the outer race 16, Fig. 5, has protuberances 24-26 which replace the housing projections, and the pressure-applying means 9 is guided in the housing 6 by shoulders 30, 31, Fig. 5, and 32, 33, Fig. 6, on the means 9, which engage the protuberance 26.

Abstract: 942,474. Double lift dobbies. RUTI MACHINERY WORKS Ltd. July 22, 1960 [July 22, 1959], No. 25620/60. Heading D1E. In a reversible double lift dobby having four rows of reading needles, the needles 3, 5 for reading successive odd-numbered picks are suspended from a bar 8, and the needles 4, 6 for reading successive even-numbered picks are suspended from a bar 9. The pattern card 2 is advanced two rows of holes at a time every second pick, the needles being lifted clear by raising both bars 8, 9. The bar 8 descends first, causing the needles 3, 5 to read the pattern for the preceding and succeeding odd picks respectively; auxiliary hooks 3<1>, 5<1> are thereby brought into the paths of auxiliary knives 10, 11. If the loom is running forward, the knife 11 operates the selected hooks 5<1> to rock bell cranks 12 which bring main draw hooks (not shown) into line with one of the main lifting knives. If the loom is being turned backwards, the auxiliary knife 10 makes an operative stroke, whereby the bell cranks 12 are rocked by the selected auxiliary hooks 3<1> to open the preceding shed. The bar 8 then rises and the bar 9 descends, whereupon the reading needles 4, 6 and auxiliary hooks 4<1>, 6<1> similarly act on bell cranks 13 to form the required even-numbered shed.

Title: Improvements in and relating to x-ray control apparatus
IPC: H05G1/46
Filed: 1944-12-21
Abstract: 586,504. Control systems for X-ray apparatus. PHILIPS LAMPS, Ltd., and NEMET, A. Dec. 21, 1944, No. 25654. [Class 38 (iv)] Energization of an X-ray tube under conditions which would result in over load, is prevented by a control voltage which is the resultant of three auxiliary voltages proportional respectively, to the logarithms of the selected anode voltage, anode current and maximum per. missible anode loading for the selected exposure time. As shown in Fig. 1, the auxiliary voltages are provided by the tapped secondary windings 2, 3, 4 of a transformer T1, the tappings being selected by switches 6-8 ganged, respectively, to the voltage, time and current setting controls of the tube. A switch 9 is also ganged with the time control and selects tappings on a further secondary winding 5. The voltage tapped from winding 3 is proportional to the logarithm of the maximum permissible anode dissipation of the tube for the selected exposure time and from this voltage is subtracted the voltage tapped from winding 2 which is proportional to the logarithm of the selected anode voltage. The voltage across switches 6, 7 is thus proportional to the logarithm of the maximum permissible current. The difference between this and the voltage tapped from winding 4, which is proportional to the logarithm of the selected current, appears across terminals 10, 101, the resultant either being in phase with or displaced by 180 degrees with respect to the primary voltage according as to whether the adjusted current is less than or greater than the maximum permissible. The resultant voltage is applied to the grid circuit of a thermionic valve functioning as a phase discriminator and which is conductive only when the resultant voltage is in phase with the primary voltage. In this condition of the valve, a relay coil in its anode circuit is energized and closes contacts in the energizing circuit of the tube, to permit exposure. Winding 5 of transformer Tl provides a voltage proportional to the-logarithm of the selected exposure time, which voltage is combined with those of the other windings to give at terminals 11, 11<1> and 12, 12<1>, respectively, voltages representative of the maximum permissible and the adjusted MA-seconds exposure, which are preferably applied to two rectifier instruments having adjacent scales and accommodated in a single housing. In installations comprising a number of different tubes which are used selectively, the various logarithmic values are tapped from potentiometers supplied from a common transformer, each tube having its own potentiometer which is brought into circuit with the transformer by the tube selector switch.

Title: Process for the treatment of molasses and sugary juices, with a view to the recoveryof the sugar
Filed: 1925-10-15
Abstract: 249,759. Deguide, C. Oct. 15, 1925. Purifying saccharine liquids.-In refining sugar juices or molasses, one of the barium silicates SiO2.BaO, or 2SiO2.3BaO, is added to precipitate and destroy the impurities, more particularly the gums and the reducing sugars, glucose and levulose, in cane sugar molasses before precipitation of the saccharate. In the example given, the finely divided silicate, mixed with its own weight of water, is added to cane sugar molasses in the proportion of one and a half molecules of baryta. to every molecule of reducing sugar present, and the temperature is raised to 85‹ C. After about 4 hours the impurities are filtered off, and the filtrate is treated with barium hydroxide to give barium saccharate which is filtered off and decomposed with carbon dioxide to obtain the sugar. The precipitate, which contains unaltered barium silicate, gelatinous silica, organic compounds of barium, and other impurities, may be calcined with barium carbonate to regenerate barium silicate. The silicate employed may 'be prepared by calcining a mixture of silica and barium carbonate in the necessary proportions, or by decomposing bibarytic silicate, SiO2.2BaO, or a more basic silicate, with hot water as described in Specifications 110,537 and 174,052, [both in Class 1 (iii), Oxides &c., Metallic]. The precipitate containing the impurities is preferably so regenerated that a more basic silicate is obtained, which can be decomposed bv hot water to give the silicate required together with barium hydroxide which may subsequently be used to form the saccharate. The use of more basic barium silicates, e.g. the bibarytic silicate, in refining sugar juices is also referred to.

Title: Hydraulic shock absorbers
IPC: F16F9/14
Filed: 1929-08-27
Abstract: 333,754. Jencick, S. Aug. 27, 1929. Fluid-friction vibration-dampers. - In shockabsorbers of the rotational or oscillating type, a plunger or vane pivoted eccentrically in a cylindrical casing is provided with convex faces which fit close up against the interior surfaces of the casing when the vane is moved to either extreme position. The vane 13, Fig. 4, is pivoted about the fixed pin 14 at the lower end of the cylindrical casing 6, and its upper end bears against a curved resilient closing sector 16. The casing is fixed to the frame of a vehicle and a.n operating arm connected to the axle oscillates the shaft 5 which is concentric with the casing and carries a cam or crank pin 22 engaging the interior of the vane. Liquid is transferred from one side of the vane to the other through ports leading into passages 28, 29 in the end cover 15. The effective area of these passages may be adjusted by screws 31, 30, to control the damping. When the vane moves towards either extreme position, it covers first one and then the other of the leakage ports thus giving increased resistance. The end cover 15 is held in positon by a screwed ring 18 and an additional outer cover 8 forms a reservoir from which leakage is made up. With this object the reservoir communicates with the interior of the casing through a passage 37 and non-return valve 40 in the pivot 14. To prevent leakage of liquid between the sides of the vane on the one hand and the end wall of the casing 6 and the cover 15 on the other hand, the edges of the vane are cut at 19 so as to provide thin resilient sealing edges upon which the pressure liquid acts. A one-way ball valve 36 is provided at one end of the passage 29 to obtain a differential action.
