IPC: F04D25/02
Filed: 1957-06-27
Abstract: 847,634. Fluid bearings. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 17, 1958 [June 27, 1957], No. 20400/57. Class 12 (1). [Also in Groups XXVI and XXXV] A two-part casing for a combined motor (see Group XXXV) and compressor or pump (see Group XXVI) supports two pairs of journal bearings 4, 5 and 6, 7 by means of flexible diaphragms 33, 34, 15, 48. One diaphragm 15 is solid but the others are perforated to allow the circulation of a gas, e.g. hydrogen, which lubricates the bearings. The hollow shafts 8, 9 are of 0.15% case hardened steel and the bearings are of " Stellite " (Registered Trade Mark.) The shafts 8 and 9 are coupled through serrated bushes 68, 72 by a third hollow shaft 14 which is sufficiently flexible to accommodate reasonable misalignment of the bearings. A thrust bearing is formed by a gimbal mounted stationary ring 89 and a rotating ring 88, the mating surfaces being optically flat, with one having spiral grooves 91 for the passage of gas for lubrication. The gas may be at a high temperature (300‹ C.) at some of the bearings.

Title: Improvements in or relating to Automatic Balling Machines
IPC: A01F15/08
Filed: 1967-05-04
Abstract: 1,162,744. Hay balers, INTERNATIONAL HARVESTER CO. 4 May, 1967 [13 July, 1966], No. 20698/67. Heading B5F. In an automatic baling machine comprising a plunger (not shown) reciprocating in a chamber 14, a needle 16 for feeding tying strands to a knotter mechanism 12, and means for moving the needle and knotter mechanism to effect a tying operation, locking means 72, 76 (Fig. 3) is provided to prevent movement of the needle 16 until the correct time for initiating the tying cycle. The needle 16 and knotter mechanism are operated through a one-revolution clutch 22 which is brought into operation when a stop member 54 (Fig. 3) on a trip arm 42 is moved out of engagement with a lug 64 of a trip dog assembly 56. This allows a roller 62 to be moved by a spring 66 into the path of a lug 68 provided on a drive sprocket 20. After the trip arm 42 has pivoted to release the trip dog assembly 56, and before the lug 68 engages roller 62, a locking projection 72 on trip arm 42 moves into engagement with a lock pin 76 to prevent rotation of the knotter shaft 24. Pin 76 is mounted on a cam 74 keyed to shaft 24. The locking means is automatically disengaged just prior to engagement of 62 and 68, by a roller 78 on the sprocket 20 engaging a cam plate 80 on the trip arm 42 (see Fig. 4, not shown). The trip arm 42 is pivoted at 46 and is moved clockwise by a spring 48 when a notch 70 on a trip rod 50 falls into a groove in a sheave 52. This sheave rotates with a metering wheel 39, the teeth of which engage the hay in chamber 14. The trip rod 50 is in frictional engagement with sheave 50. Modification.-Figs. 8, 9 (not shown) show a modified locking means comprising a yoke (106) pivoted at (104) to the trip arm (100) and having a projection (110) adapted to engage a lug (112) on a carrier (94) keyed to the knotter shaft (90). The locking means is released by a cam (116) engaging a roller (114) on the yoke (106).

Title: Improvements in or relating to hoists
IPC: B66F9/02
Filed: 1944-10-25
Abstract: 585,637. Loadhandling machines. WICKSTEED, I. B., and WILKERSON, A. F. Oct. 25, 1944, No. 20786. [Class 78 (iii)]- In a hoist of the kind comprising an arm which is adapted to carry a load and is pivotally mounted on a support so that it can be swung from a lowered position to a raised one, the arm is provided with one or more normally fixed chairs or cradles for'supporting the article to be lifted. The arm 10 is pivoted at 14 in vertical members 5 secured to a wheeled vehicle 1, and is provided with a cradle 15. This cradle may be adjustable along the arm and secured in any position by pegs. Links 24 pivoted to the arm are pivoted to links 25 which are connected by springs 26 to anchorages on the vehicle. These springs initiate the return movement of the arm from the vertical to the horizontal position. The arm is raised by a cable 21 which is anchored to the members 5 at 22, is passed round a series of pulleys 18, 19 on the arm and vertical members, respectively, and is led under a pulley 20 to a winch or vehicle. The base of the hoist may be lowered into contact with the ground for stability by mounting the wheels 27, Fig. 4, in the free ends of pivoted bars 28. When the wheels are in running position, the ends of each bar 28 are engaged by the end of a catch plate 30 which is pivoted to the vehicle at 31 and carries a sliding counterweight 32. Stops 34 prevent movement of the plates 30. It is stated that these plates can be released by moving the counterweights from the position shown in full lines to that shown in broken lines and by rocking the hoist to one side.

Title: Fuel-injection equipment for diesel engines
IPC: F02M59/18
Filed: 1951-09-03
Abstract: 716,380. Fuel injection pumps. GANZ VAGON-ES GEPGYAR. Sept. 3, 1951 [May 16, 1951], No. 20790/51. Class 102 (1). In a fuel-injection system in which a pump delivers to an open nozzle, the delivery is of the pump is effected by a spring released intermittently by a cam and lever system to obtain a preliminary injection. Fig. 1, shows an arrangement in which the pump piston 1 is pressed by a spring 13 into engagement with a block 9 loaded by a spring 10. The block 9 is pivoted on a lever 7 pivoted at 21 on a second lever 8 which carries a roller 14 engaging a pin 15. The levers 7, 8 have noses 20, 19 respectively that engage a cam 11 having a radial surface 12. As the cam 11 rotates, the nose 19 is first released by the surface 12 thereby allowing the lever 8 to rise until the projection 23 engages the abutment 24; during this movement, the pivot 21 is raised and lever 7 turns about its point of engagement with cam 11 and the spring 10 moves the piston 1 to deliver a preliminary injection. When the nose 20 is released by the cam, the main injection is delivered until the block 9 engages the surface 30. The stroke of the pump is varied by adjusting the pin 15 vertically by a member 16 moved by a slide 17 in a direction perpendicular to the plane of the figure and wedge-shaped in that direction; the slide 17 is connected to the engine governor and a manual adjustment 18 is provided. The abutments 23, 24 may be replaced by a step on the nose 19. In alternative arrangements, a single lever may be provided and either have a stepped nose or co-operate with a cam having two steps. The pump piston is provided with a valve 6 and suction takes place through ports 4.

Abstract: 698,988. Fluid-actuated valves. BASTIDAS E. A. Sept. 10, 1951, No. 21243/51. Class 135 [Also in Group XXXIV] A safety cut-off valve in a hydraulic braking system for isolating a fractured or leaky pipe from the remainder of the system comprises a casing 2, Figs. 1, 2, having a base-plate 9 mounting a pair of cylinders 12 connected at one end by passages 18, 19 to a master pump 1 and having at their other ends outlets 24 connected by pipes 3, 4, to the brake cylinders of the front and rear brakes respectively. Each cylinder contains a plunger 30 having clearance between it and the cylinder and notches 42 which permit restricted flow when the plunger co-operates with an annular seat 20. Normally, on application of the brakes, pressure liquid from the inlet passage 19 passes through the notches and the clearance and the plunger " floats " between the cylinder ends. On a sudden reduction of pressure at the outlet 24, the associated plunger seats on the cylinder face 28 to isolate the pipe connected therewith. In a modification, both cylinders may be as cylinder 13 and have plungers 33 urged downwardly by springs 48. Pressure liquid in this case normally flows through notches 43 in the plunger flange 44 and around the coned end face 31 engageable with a seat 29 at the top of the cylinder on a sudden fall of pressure at the outlet. Bleeders 36 permit the expulsion of air from the cylinders.
