Title: Piston engine or pump
IPC: F04B9/02
Filed: 1976-08-03
Abstract: 1525779 IC and steam engines; reciprocating pumps and motors E HARR 3 Aug 1976 [9 Aug 1975] 32301/76 Headings F1A F1B and F1M The reciprocating piston of an engine or pump has its centre of gravity offset from the longitudinal axis of reciprocation and is constrained to rotate about the longitudinal axis during the reciprocation. The centre of gravity consequently has a rotating motion instead of a reciprocating motion. An I.C. engine, Figs. 1 and 3, comprises a piston 51 reciprocating within a cylinder provided with a combustion chamber 58 at each end. The cylindrical wall of the piston is thickened in one region so that the centre of gravity of the piston is displaced from the longitudinal axis. Arms 60, 61 extending laterally from the piston are articulated at 65 to gear-wheels 62 which are rotatably mounted on spindles 63 and which mesh with a contrate output wheel 66. The connection of the arms 60, 61 to the gear-wheels 62 constrains the piston to carry out an oscillatory rotation about its longitudinal axis during reciprocation, whereby a corresponding oscillatory rotation is imported to the wheels 62, 66. The wheels may be bevel gears. In another embodiment, Fig. 4, the piston 131 is pivotally connected at its offset centre of gravity 135 to a drive wheel 134 which penetrates the cylinder 132 at, say, 45 degrees to the longitudinal axis and is guided in slots 141, whereby the piston undergoes a combined reciprocatory and rotary motion and the wheel 134 rotates. The wheel 134 may be provided with counterweights to counteract the centrifugal force of the piston. Fig. 6 shows an engine in which the piston 181, which again has an offset centre of gravity, is connected to an output wheel 196 (which is counterweighted) via a ball joint 193 and a link 192 which can swing about a pivot pin 194. Instead of being an I.C. engine, the machine may be an engine operated by steam, compressed air or oil under pressure or may be a pump.

Filed: 1945-11-30
Abstract: 622,104. Ink-ribbon mechanism. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 30, 1945, No. 32368. Convention date, Feb. 21. [Class 100 (iv)] [Also in Group XIX] Ribbon-feed and reversing mechanism in apparatus for recording data by printing (see Group XIX), comprises two spool plates 400, 402, having ratchet teeth 406 arranged for the actuation of the plates in opposite directions. An actuating bar 412 carries a double-ended pawl 420 with down-turned fingers 422, 424 arranged to co-operate with one ratchet or the other according to whether the pawl 420, biassed by a spring 428, inclines to one side or the other of an unstable dead-centre line. A slidable trip plate .436 has spaced trip arms 438, 440 and ribbon-feed forks 442, 444 such that when an eyelet in the ribbon meets a fork 442 or 444 it shifts the plate 436 so that an arm 438 or 440 strikes the pawl 420 and tilts it to engage the other ratchet 406, thus reversing the ribbon-feed. As the shaft 238 revolves, in each record-taking cycle, an eccentric cam 433 on a hub 359 reciprocates a bell-crank lever 437, whose upper end engages a slot 445 in a pivoted lever 447, which in turn reciprocates the actuating bar 412 and causes the pawl 420 to advance the ratchet with which it is engaged, with the co-operation of one of two spring- retaining pawls 446, 448 embraced between the down-turned fingers 422, 444, thus advancing the ribbon.

Title: Improvements in couplings, more particularly for connecting tail members to aerial bombs and for the interconnection of pipes and other bodies
IPC: F42B30/08
Filed: 1937-11-25
Abstract: 503,976. Pipe couplings. CLARKE, F. A., and AVRI PRODUCTS, Ltd. Nov. 25, 1937, No. 32532. [Class 99 (i)] [Also in Group XXV] Relates to a coupling, more particularly for the interconnection of a cylindrical tail member and an aerial bomb or for interconnecting a pair of pipes, comprising relatively rotatable complemental male and female members having two or more circumferentially spaced arcuate cam or wedge surfaces on their outer and inner peripheral faces respectively for causing interlocking of the members on relative angular displacement without lateral displacement of either member from its longitudinal axis. According to the invention, the outer and inner surfaces of the male and female members respectively are ,similarly or relatively tapered longitudinally, the degree of longitudinal taper and radial dimensions of.each of the wedge surfaces being such that the maximum radius of the male member at its leading end is greater than the minimum radius of the female member at its outer end. Preferably, the difference between the radii, measured at the circumferentially spaced opposite ends of a wedge or cam surface at the wider end of either the male or the female member is greater than the difference between similar radii of the same wedge or cam surface of the same member but at the narrower section or end of said member. The maximum radius of the male member at its leading end is also preferably greater than the minimum radius of the female member at its inner end. As shown in Figs. 1 and 2, the male member 10 is tapered inwardly from its leading end 12 whilst the bore in the female member 11 is similarly tapered from its inner end 10 to its outer end 14. The outer periphery of the tapered part of the member 10 is formed with cam surfaces 15, 16, 17 whilst the inner periphery of member 11 is provided with cam surfaces 20, 21, 22. If desired, a key may be provided on the male member adapted, when the members have been relatively rotated into locking position, to be moved longitudinally into one of the gaps between the cam surfaces in order to prevent accidental reverse angular displacement of the members. When the female member is not provided with a closed end, a collar 34 may be provided on the male member adapted to abut against the bounding wall constituting the outer end of the female member in order to prevent axial displacement of the members beyond the locking position. Figs. a and 6 show the invention applied to a coupling for pipes, a washer 33 being provided to prevent leakage.

Abstract: 996,165. Automatic exchange systems; transistor pulse circuits. STANDARD TELEPHONES & CABLES Ltd. Aug. 23, 1963 [Aug. 24, 1962], No. 32643/62. Headings H3T and H4K. In an arrangement for monitoring the current flowing in the highway of a time-division multiplex system, the input of an amplifier VT4 is connected across an impedance in the highway H so that the amplifier output current is determined by the current in the highway. The output of the amplifier VT4 is connected to threshold devices VT7 and VT8, which respond to different current levels (corresponding to, say, " existence of connection " and " speech " respectively) and may be normally disabled by saturated transistor shunts but enabled at the time position of the relevant channel, Fig. 6 (not shown). A diode may be provided for clamping the collector voltage of transistor VT4, Fig. 3 (not shown). The output current of monitoring amplifier VT4 may be amplified to the level of the highway current itself, Fig. 7 (not shown). A plurality of monitoring devices VT4 may be connected at different points along the highway and arranged to be of alternate PNP and NPN types so that the highway current is not substantially affected.

Abstract: 682.603. Endless-chain mining-machines. AUSTIN HOY & CO., Ltd. Dec. 20, 1950 [Dec 20, 1949], No 32650/49. Addition to 630,112. Class 68(i) To permit an overcutter or an undercutter jib to be moved vertically away from the normal plane of operation so as to facilitate the flitting of the machine it is arranged that in the case of an undercutter the jib post 124 of the jib 23 is pivotally connected by guide links 25 which in turn are pivotally connected to a back hanger bracket 16 that can be rotated about the vertical drive sprocket axis 14. When in the lowermost position i.e. the jib is adjacent the floor, a block 22 on the jib interlocks with a block 19 on the bracket, the two blocks being clamped together by a screw 21. On release of the screw, the jib can be swung upwards and outwards because of the guide links until it lies in the plane of the drive sprocket so as to be ready for rotation about the axis of the sprocket 14. In this position, the blocks have been separated from one another and, to hold the jib in such a position, a pin 28 is passed through a hole 30 in the block to rest on a knee 29 formed on the block 19. In a modification, the interlocking faces of the blocks are in the form of an outwardly inclined dovetailed connection whilst the hinged guided sections are provided with enough play at the hinges to permit of such sliding. In another modification, the guide sections are replaced by a link connecting the jib post and hanger bracket and the guides on the jib post and bracket are so curved as to lead the chain from one to the other when in the working position and to be sufficiently separated from one another in the position in which the jib is moved away from the working plane as to permit the chain to extend loosely between them. Specification 626,080 also is referred to. The Provisional Specification describes also modified means for locking the jib to the hanger bracket when in a raised position.

Abstract: 1448321 Grinding GLEASON WORKS 25 July 1974 [24 Aug 1973] 32912/74 Headings B3D and B3K A stock removing machine comprises a working tool 10, such as a grinding wheel or cutter mounted for rotation about the axis of a spindle 14 for engagement with the surface of a workpiece 12, such as the chamber of a rotary engine, supported for rotation relative to the tool, and supporting means for the workpiece consists of a table means 20 which is rotatable and connected by coupling means 24 to a holding means 18 for the workpiece spaced from the table means, the coupling means preventing relative angular rotation between the table and holding means but permitting radial displacement therebetween, and second resilient means in the form of spring elements 26 interconnecting the table and holding means for developing a predetermined radial force between the tool and workpiece so that the workpiece can precisely adjust its position according to a previous shape of the workpiece. The machine may be used for grinding or finishing the epitrochoidal shape of the cylinder wall of a rotary engine housing and have a cylindrical grinding wheel 10, Fig. 2, which is mounted by a sleeve 32 on a flexible diaphragm 38 secured to an extension 36 of a spindle 30 of the machine. The diaphragm permits angular movement between the wheel 10 and spindle 30 to an extent limited by a gap 46 of 0À0012 to 0À0016 inch between the sleeve and extension. The supporting means for the workpiece consists of a table 20, Fig. 3, rotatable by a spindle (not shown) and having four post-like structures 52 connecting the table to the holding means 18 from which the workpiece is suspended. Each structure 52 has respective parts connected to the table and holding means, the parts having bearings therebetween which permit limited lateral movement between the table and holding means. Two further post-like structures 24 having Oldham type couplings extend between the table and holding means and permit radial displacement between the table and holding means. Six beam spring elements 56, which constitute the second resilient means, extend from the holding means 18 for engagement with cups 58 on the table 20. The cups 58 are formed on the pistons 60 of cylinders and can be selectively retracted to vary the resilient resistance as the grinding wheel engages different parts of the workpiece, for instance, in the vicinity of inlet and exhaust ports. The workpiece is clamped to the holding means by members 22 acted upon by springs 66. Hydraulic means 80 can be actuated against the springs to release the workpiece. The spindle 14 of the tool is driven by a motor 104, Fig. 5, of an upper assembly 104 and is movable by gearing 114, 116 and cam 118 driven by a motor 106. A further pair of worms 108, 110 rotate the workpieee 12 carried by the table 20 and holding means 18 so as to generate a trochoidal shape on the workpiece.
