Abstract: 1,262,714. Correcting weight and mass distribution. SNYDER CORP. June 26, 1969 [June 27, 1968J, No.32274/69. Heading G1N. A machine for reducing the weight and altering the mass distribution of a workpiece by removing material from selected portions 14, 16 includes a sensing station at which the positions of portions 14, 16 and the weight and mass distribution are measured and a second station at which material is removed from portions 14, 16 under the control of signals derived when the workpiece was at the sensing station. At the sensing station, differential transformers (48, 50) convert the displacements of scale platforms 26 into respective electric signals and differential transformers 78, 80 convert the positions of contact probes 64, 66 into electric signals. The signals from 48 and 78 are amplified and summed at 86 Fig.4 and stored in a capacitor. The workpiece is then progressed to the milling station where nullseeking control systems including respective differential transformers 44, 46 for sensing the position of the respective milling units 18, 20 cause appropriate amounts of material to be removed from portions 14 and 16 of the workpiece. Stops 98, 100 limit the forward travel of the milling units. The probes 64, 66 are provided with lost motion devices and travel-limiting stops 74 Fig.2 (not shown). The weighing and probing need not be done simultaneously; if done sequentially, a memory is required for the output of amplifier 82 or 84 as appropriate.

Title: Improvements in x-ray apparatus
IPC: A61B6/00
Filed: 1960-09-23
Abstract: 961,176. X-ray examination apparatus. COMPAGNIE GENERALE DE RADIOLOGIE. Sept. 23, 1960 [Sept. 23, 1959], No. 32772/60. Heading H5R. An X-ray tube is mounted movably with respect to an examination table top, driving means being provided which acts through a differential gear connected to two driving devices, one of which moves the tube vertically and the other horizontally. In the form shown, the X-ray tube 1 is supported by a carriage 2 which can be displaced vertically along a pillar 6. The pillar 6 is itself rigidly mounted on a wheeled carriage 7, so that it can be moved bodily along a horizontal track. An electric motor 10 drives a shaft 13 which in turn drives a shaft 14, either directly through a coupling 12 or indirectly through reduction gearing 34, 35 and another coupling 32. Shaft 24 carries a pinion 15 which drives a gear 16 fixed to the cage 17 of a differential unit, the cage carrying opposed planetary gears 29. These mesh with the output or sun gears 19, 21. Sun gear 19, via its shaft 31 and a further gear 30, effects vertical displacement of carriage 2, and the other sun gear 21, via shaft 50 and a further gear 23, effects horizontal displacement of carriage 7. Carriage 2 is pivotally connected to a tie rod 25, rigidly attached at its other end to a carriage 24 displaceable along the table. If the table is horizontal, the resistance to vertical movement of the X-ray tube is a maximum, and the movement of the tube can take place only in a horizontal direction. Similarly, if the table were vertical, movement of the tube could only take place vertically. When the table is inclined, movement of the tube can take place in both directions simultaneously, the relative amounts depending on the degree of inclination.

Title: Improvements in method of producing artificial silk or the like
IPC: D01D7/00
Filed: 1930-10-31
Abstract: 372,279. Winding artificial silk. BRENZINGER, J., Fairfield, Connecticut, U.S.A. Oct. 31, 1930, No. 32834. Convention date, June 20. Void [Published under Sect. 91 of the Acts]. [Classes 120 (ii) and 120 (iii).] In the production of artificial silk &c. by the bobbin spinning method, the newly-formed thread is wound crosswise into a superposed series of slack convolutions, the slack being of sufficient amplitude to admit of subsequent shrinkage without imposing unequal strain on different portions of the material. The slack in the convolutions facilitates washing and dyeing. To ensure uniformity in the thread, the supply of spinning solution is proportioned to the speed of take-up. As shown, a pump 1 supplies spinning solution to a jet a in a bath 3 and the issuing thread 4 is laid crosswise on a spool 5 by a thread guide 6 which is reciprocated across the spool by rack gear 69, 70, Fig. 2, and is also vibrated about an axis 71 by a crank pin 75, link 73 and lever 74. The gear 69 is oscillated by a rack gear 67, 65 actuated by a cam 64 on a shaft 63. The thread is thus laid in a series of convolutions b, Fig. 3, with undulations d. To ensure uniformity in the thread, the supply of solution is increased as the diameter of the spool increases, the spool being driven at constant speed. The spool shaft 8, Fig. 1, is driven from a motor 9 through chain gearing 11 and shaft 13 ; the pump 1 is driven from the shaft 13 through a variablespeed belt transmission 20, shaft 21 and gearing 22..28. The belt 20 is progressively adjusted by a wedge 42 moved by rack gear 43, 44 actuated by two sets of ratchet gear 45, 51, driven by an eccentric 53 in turn driven from the shaft 8 through a belt 55. Instead of increasing the pump speed, the speed of the spool may be gradually diminished.

Filed: 1922-12-07
Abstract: 205,390. Blakeborough, R. A., (Larner- Johnson Valve Engineering Co.). Dec. 7, 1922. Safety-valves.-A pressure relief valve designed to relieve sudden rises of pressure and particularly adapted for use on a pipe line supplying water to a turbine of a water power plant or on the discharge line of a pump, is normally held closed by a compressed gaseous medium the pressure of which is regulated by the pressure of the controlled fluid. The valve plunger 5 works in a cylinder 2 supported by radial webs within a circular casing provided with contracted ends and is adapted to engage a seat 6 having a smaller cross sectional area than the plunger. The plunger has a flexible packing ring 10 adapted to engage a seat 11 when the valve is closed to prevent leakage. The cylinder 2 has a port 13, controlled by a check valve 15 with a bye-pass 16, leading to a tank 14 in which a volume of air is trapped. The water level in the tank is adjusted by admitting compressed air through a pipe 18 and the lower part of the tank is connected to the main conduit by a small pipe 17, so that slow variations of pressure in the main conduit are transmitted to the tank and the pressure of air maintained equal to the pressure in the main conduit. A valve controlled pipe connection 12 is provided to enable conduit pressure to be supplied to the cylinder 2 for resetting the valve in cases where the passage 16 is not made, sufficiently large to supply the leakage past the plunger.

Title: Improvements in or relating to bolster supports for bogies incorporating rubber or the like springs
Inventor: HIRST ARCHIE JOHN
IPC: F16F1/54
Filed: 1955-11-22
Abstract: 805,325. Resilient mountings; rail vehicle undercarriages. METALASTIK, Ltd. Aug. 24, 1956 [Nov. 22, 1955], No. 33493/55. Classes 103(6) and 108(3) The invention relates to a spring support for a bolster 5 by means of rubber blocks 8 in combined shear and compression, from a bogie frame 6, the blocks being arranged in pairs at respective ends of the bolster 5. According to the invention, the blocks 8 of each pair are spaced lengthwise of the bolster and overlap so that their compression axes, within the length of the blocks, are in X-formation. As shown, each end of the bolster is formed with transverse platelike members 7 to form a pair of cells, in each of which lies one of the resilient support blocks. Each of the latter is disposed between a partition 9 rigid with adjacent members 7, and a member 11 rigid with the sole bar 10 of the bogie frame, or with a plate 13 upstanding from a bridge piece 12 carried by the transoms 6 of the bogie frame. Each block 8 comprises a pair of elements 14 separated by a metal plate 15. Each pair of plates 15 are rigid with a coupling plate 16. Each element 14 may be provided with metal interleaves.

Patent GB-1322538-A (GB)
Title: Fuel injection pumps for internal combustion engines
IPC: F02M41/14
Filed: 1970-07-10
Abstract: 1322538 Fuel injection pumps ROTO-DIESEL 10 July 1970 [10 July 1969] 33575/70 Heading F1A In a fuel injection pump comprising radial pistons reciprocated in cylinders in a rotary distributor 3, a radial spill port 13a in an axially adjustable ring 13 co-operates with radial passages 40 connected to the pumping chamber to control delivery. The ring 13 is urged to the left (delivery increase) by springs 36 to a position abutting a stop 16x on a bell crank lever 16. At start-up the lever 16 positions the ring 13 so that no spillage occurs. With increasing speed, a feed pump 1 builds up pressure to lift a piston push-rod 12 and rotate the bell crank, and thus move the ring 13 to the right. An adjustable spring loaded plunger 30 bears on the lever 16 to modify the spring force due to the springs 36. The stop 16x thus determines the maximum fuel delivery for all speeds. Axial adjustment of the ring 13 is also effected by a sleeve 24a urged to the right by flyweights 24 and to the left by a spring 25 acting through a lever 26. The tension in the spring 25 is a function of the accelerator setting of the associated engine. Fuel enters the pumping chamber during the suction stroke through one of the radial passages 9 aligning with a passage 6 fed by the feed pump 1. During the delivery stroke a radial passage 8a aligns with one of the delivery ducts 22 leading to the injectors. A device 15 automatically rotates a cam ring operating the pistons to effect a change in the timing. The ring 13 is rotated by a similar amount since it slides on guides 37 fixed to the cam ring. This rotation may cause simultaneous axial adjustment of the ring 13 if a cam surface is provided on the ring 13 where it contacts the stop 16x, Figs. 13 and 14 (not shown). In the event of the ring 13 seizing to the rotary distributor 3, an auxiliary chamber (45) radially extending from the ring 13 and in constant communication with the pumping chamber is caused to be broken off, so that pump pressure is lost. The radial passages 40 may be arranged to co-operate with a spill slot (136), Fig. 15 (not shown) in the ring 13 thereby to produce a twostage injection.
