Abstract: 1,162,048. Expanding-pulley gearing. TOS KURIM. 13 June, 1967 [17 Oct., 1966], No. 27123/67. Heading F2D. In an arrangement for maintaining the belt tension in an expanding-pulley gear the ratio adjusting levers 8 are mounted on supports 7 carried by a cross shaft 1 and associated with stop members 15 preventing outward return movement of the supports. The members 7 are urged inwardly by compression springs 6 loaded by threaded nuts 13 on the shaft 1. Each of the stop members 15 carries a lever 16 attached to a setting spring 17 connected to the adjusting lever 8, and a return spring 18 connected to the support 7. In addition each stop member is formed with a series of radial cam surfaces engaging axial pins 21 bearing against set screws 22 in the support 7. In operation reduction of belt tension is avoided by rotation of the stops 15 under the influence of springs 17, 18 whereby the cam surfaces operate continuously to force pins 21 and screws 22 inwardly to counteract any outward shift movement of the supports 7.

Abstract: 646,012. Ball mills. SOC. ANON. USINES. E. HENRICOT. Sept. 11, 1946, No. 27344. Convention date, Aug. 17, 1943. [Class 59] A ball mill having a lining provided with cells which form partial seats for the balls is characterized in that, for at least part of the lining, the cells are arranged in the form of a network of regular polygons which have at the maximum four sides the length of which is equal to the mean diameter of the ball load. The lining consists of base plate 4 cast with projections 5 which support the balls and with intermediate projections 11 of less height than the projections 5. The projections 5 are so disposed that a layer of balls 6 resting thereon is arranged in the form of a square network. In a modification, Fig. 4, the projections 5 produce a network of equilateral triangles, further projections 14, of greater height than the projections 5, being provided. In a mill where a number of various sizes of balls are employed, e.g. a conical mill. the lining may consist of a corresponding number of portions of appropriate sizes, so that the dimensions of the lining and the size of the balls decrease from the inlet end to the outlet end of the mill. These arrangements of projections are stated to give a maximum stability to the structure of balls which, as the mill rotates, attain a greater height before falling, producing a greater crushing effect. The Specification, as open to inspection under Sect. 91, describes also an arrangement wherein the projections 5 produce a network of isosceles triangles. This subject-matter does not appear in the Specification as accepted.

Title: Variable displacement pumps
IPC: F04B49/00
Filed: 1972-06-14
Abstract: 1333540 Reciprocating pumps CATERPILLAR TRACTOR CO 14 June 1972 [28 June 1971] 27894/72 Heading F1A [Also in Division G3] The swash-plate inclination of a variable-displacement, axial-piston pump is controlled by cartridge assemblies 46, 70 detachably mounted in the pump housing and interchangeable to reverse the direction of flow of the pump, assembly 46 including a spring 40 for biasing the swash-plate 32 into its maximum displacement position shown, and assembly 70 including a piston responsive to a pilot pressure to bias the swash-plate into its minimum displacement position. For reversing the flow direction, housing end 16 is removed and the cartridge assemblies and stops 52, 84 interchanged. In operation, e.g. for operating a plurality of implements in a backless hydraulic circuit, the driving engine is started with the swash-plate at maximum inclination. If all the implement valves are closed, a pilot pressure is applied to a valve (54), Fig. 1 (not shown), which connects the pump output pressure via pipe 60 to chamber 68 of piston 80 to reduce the swash-plate inclination to a minimum. When an implement control valve is opened, the pilot-operated valve (54) connects both pipe 60 and pipe 62 to output pressure, which acts via pipe 62, groove 86 and passages in assembly 46 on a piston 48 in chamber 116, Fig.3, to move the swash-plate into maximum inclination. When a predetermined output pressure is reached, piston 122 is moved upwardly against spring 124 to supply a predetermined proportion of the output pressure to a servovalve spool 102, Fig.3, in assembly 46, which moves upwardly against a spring 158 to connect chamber 116 to tank (the pump housing interior) via passage 172. The swash-plate inclination is then reduced by piston 80, thereby moving servovalve sleeve 44 to provide a follow-up action. When a further predetermined pressure is reached, valve 106 opens and directs output pressure to move the servovalve spool and sleeve upwardly for rapid movement of the swash-plate into minimum inclination. In Fig. 5 (not shown), an underspeed valve provides an external pressure source for actuating the servovalve assembly. In Fig.6  (not shown), the servovalve assembly is connected by a rod to a spring-loaded piston connected to groove 128 receiving the controlled proportion of output pressure. Alternatively, the groove connection and rod connection may be replaced by a connection from an external pressure source to the servovalve connection (204).

Slide 16 has seats 17, 18 for locating a boring tool 19, and is locked in body 13 by a rod 27 having a flange 31, which is urged to the left, Fig. 3, by a stack of Belleville washers 25. A nut 28 is secured to body 13 and is in screw threaded engagement with a gear 36 which meshes with a rack 38, Fig. 6, formed on a cylinder 39. The latter carries a roller 43 which cooperates with face 56 of bar 58. Slide 16 has a roller 54 mounted thereon, and is spring-urged downwardly by springs 50, Fig. 5 (not shown). In operation, tool head 12 is mounted in spindle 9, which is oriented until slide 16 is in a vertical position. Tool 19 is fixed in the required seat 17 or 18, and the position of the tool head is controlled by a numerical control apparatus. Work-table 11 is moved until face 56 of bar 58 contacts roller 43, and spindle 9 is moved vertically until roller 54 contacts face 57 of the bar. Table 11 is moved further to the right so that roller 43 overcomes spring 48, Fig. 6, rack 38 causes gear 36 to rotate in the anticlockwise direction so that it is unscrewed from nut 28, Fig. 3, and moves rod 27 to the right and slide 16 is unlocked. Spindle 9 is moved vertically so that slide 16 with tool 19 is moved to the required position. Table 11 is moved in the opposite direction so that face 56 is disengaged from roller 43 and spring 38, Fig. 6, moves rack 38 so that gear 36 is screwed into nut 28 and slide 16 is locked by springs 25, in the adjusted position.
