Title: Improvements in or relating to clutch control mechanism
IPC: F16D43/26
Filed: 1948-09-07
Abstract: 694,301. Switches held set and freed mechanically. EASON, C. M. Sept. 7, 1948 [July 12, 1948], No. 23568/48. Class 38 (v) [Also in Groups XXIV, XXIX and XXXIV] A ratchet cam wheel 172, Figs. 4 and 5, actuating through an arm 163 a switch button 162 controlling a friction clutch (see Group XXIV) between the driving flywheel and crankshaft of a punch press, is stepped round alternately by a manuallyoperated pawl-ended plunger 192 and a pawl rod 209, constantly reciprocated by an eccentric 213 from a shaft'236 driven from and rotating synchronously with the press crankshaft and swung into the path of the wheel 172 by a manuallyoperated plunger 217 The plunger 192 supplies a relatively long stroke causing the nose 171 of the arm 163 to ride, from the position shown, up on to the flat top of the next one of the teeth 176 on the wheel 172 with consequent depression of the button 162 to initiate clutch engagement, the wheel 172 being then located frictionally by ball detents 181 seating in depressions 183 in the wheel; the rod 209 supplies a relatively short stroke completing the advance of the wheel 172 by one tooth and allows the arm 163 to rise under the action of an adjustable spring 168 and release the button 162 to initiate clutch disengagement, the nose 171 being then resiliently held against the radial face of a tooth 176 by the balls 181 acting against the sides of the appropriate depressions 183 under the bias of a spring 185 which urges the wheel 172 axially along splines 179 towards the balls. The plunger 217 is retracted by a spring 225 and is connected via a lost motion spring link 221, a further plunger 228 and a pivoting strut 264, Fig. 8, to a push-button 263 which, to stop the press during continuous working, can be directly manually depressed, and, for single stroke working, can be locked down by a hand lever 286 rotating about the axis of the push-button and operating on it through a sleeve 283 in screw-threaded engagement with a supporting panel 268. The plunger 192, which is retracted by a spring 197 and held up to its work by an adjustable spring 205, is directly connected, also by a pivoting strut, to a similar pushbutton actuable, by direct manual depression only, for press starting. The point in the press stroke at which clutch disengagement occurs can be varied by a circumferentially adjustable coupling 245, 247 in the drive from the shaft 236 to the eccentric 213. A pointer 245 rigid with the shaft 236 engages notches in the rim of a graduated annulus 247 which is slidably splined on the eccentric 213 so that it can be pressed back against a spring 254 clear of the pointer and rotated relative thereto to a new position of adjustment. The clutch always disengages at the set point in the press stroke regardless of when the pushbutton 263 is depressed, the link 221 allowing such depression at all times.

Filed: 1963-06-13
Abstract: 1,042,515. Steering vehicles. MASSEYFERGUSON Inc. June 13, 1963 [June 14, 1962], No. 23576/63. Heading B7H. A tractor direct power steering system comprises a track rod 18 actuated through a link 20 by a jack 28 under the control of a closed centre valve 38, pressure fluid being supplied from a reservoir 42 by an engine driven pump 44, the spool of valve 38 being actuated by a pump mechanism 51 drivingly connected to a steering- wheel 56. When the pump 44 is not working, the fluid is supplied to the jack 28 from the manually operated pump 51 through the valve 38. The pump 51 is mounted in a housing 52 carried by a yoke 62 pivoted at 66 to a support member 60 having a slot 70 through which the yoke extends, the latter having suitably curved portions provided with flanges 72 for limiting the rotational movement of the yoke. A circular section rod 74 of curved configuration concentric with the pivots 66 is mounted on the yoke 64 and passes through a spring ring 76 whose ends are attached to the hub 80 of a lever 82 urged by a spring 88 in a direction to tighten the spring ring 76 about the rod 74 whereby it, and the yoke 62, is locked in given position. Rotation of the lever 82 against the pressure of spring 88 releases the lock of rod 74 whereby the yoke 62, and steering wheel 56, may be positionally adjusted.

Title: Improvements in or relating to electrical frequency meters
IPC: G01R23/02
Filed: 1951-10-10
Abstract: 690,158. Bridge circuits. SANGAMO WESTON, Ltd. Oct. 10, 1951 [Nov. 18, 1950], No. 23606/51. Class 37. A frequency sensitive bridge comprises a pair of impedances forming two adjacent arms at a bridge input junction, a load connected across these bridge arms, and an opposite pair of bridge arms connected through a reactor to a frequency input terminal in which opposite arms the mutual inductance of the reactor is balanced against capacitance whilst the self-inductance of the reactor secondary is balanced out at the bridge balance frequency. As shown, two adjacent arms are formed by equal resistors 10, 11 at one input junction, whilst the opposite arms include a capacitor C and the two secondary windings 13, 14 of a reactor 15, balanced for the condition of equal reactance. An indicating instrument 16 is connected across one diagonal and the frequency to be measured is applied across the other diagonal through input terminals 17, 18 and the primary winding 20 of the reactor. The secondary windings 13, 14 are in mutual opposition so that the selfinductance of the secondary cancels at bridge balance, leaving only the primary-secondary mutual inductance effective in the bridge. The temperature coefficient of the capacitor C may be corrected by the choice of a dielectric giving an appropriate coefficient of resistance, and the level coefficient of the reactor may be compensated by a non-linear resistor. The reactor 15 may comprise a two-legged core, each leg carrying portions of the primary and secondary windings, corresponding portions being of equal turns and connected in resistive and reactive symmetry. The resistors 10, 11 may be replaced by equal capacitors. The instrument 16 may be replaced by a dynamometer instrument having crossed movable coils connected in series across the bridge diagonal, and a field coil connected in series between the frequency source and a bridge input junction. A resistor may be connected in parallel with the field coil for compensating the phase shift due to bridge reactance. The instrument 16 may be a D.C. instrument, rectifier elements being connected in a pair of bridge arms and further rectifier elements being cross connected between these arms and the D.C. instrument to form a series loop constituting a modulator bridge. A resistor may be connected in series with the secondary coil 14 to compensate for residual leakage reactance.

Title: Improvements relating to pump controlling means applicable to fuel pumps for internal combustion prime movers
IPC: F02D3/02
Filed: 1945-09-13
Abstract: 599,106. Fluid-pressure servomotorcontrol systems. LUCAS, Ltd., J., and IFIELD, R. J. Sept. 13, 1945, No. 23646. [Class 135] In a variable delivery pump, e.g. for supplying fuel to an internal-combustion prime mover, the output of the pump is regulated by fluid-actuated means controlled by a valve the operation of which is dependent on the pressure difference across a throttle valve which varies the rate of delivery of the fuel in accordance with the demand. As shown in Fig. 1, the valve v, which is disposed in a housing u, controls the leakage from one side of a spring- loaded piston o connected to the adjustable swash-plate e of a rotary pump having an inlet i and an outlet k, the latter communicating through a duct r and a restricted passage s with the opposite sides of the piston. The valve v is mounted at one end of a lever loaded at its opposite end by a spring y and a diaphragm 7 the opposite sides of which are connected by pipes 9 across a throttle valve 3 actuated through rack-and-pinion gear by a lever 4. In a modification, the lever pivots on a diaphragm 12, Fig. 2, dividing the housing u<1> into parts 10, 11, the former of which contains a capsule 13 exposed on its outside to atmospheric pressure and bearing upon the lever.

Filed: 1933-04-18
Abstract: 402,377. Friction clutches. HARDY, SPICER, & CO., Ltd., Birch Road, Witton, Birmingham.-(Automatic Drive & Transmission Co. ; 554, South Broadway, Gloucester City, New Jersey, U.S.A.) April 18, 1933, No. 23658. Divided on 399,421. [Class 80 (ii).] In a centrifugal clutch comprising a driven plate 16 disposed between a driving flywheel 11 and a presser plate 20 rotating with the latter, weights 32 are carried by stems 31 which extend through slots in a spring-supported plate 22 rotating with the flywheel and which carry at the other end feet 33 engaging between the adjacent surfaces of the plates 20, 22. Above a predetermined speed, the plate 20 is moved, by the tilting of the feet 33, to the left to engage the plate 16, the reaction being taken by the springs 46 supporting the plate 22. The springs 46 abut against a plate 49, and the free ends of radial levers 50, which are fulcrummed on links 44 pivoted to brackets 43 on the flywheel and which are pivotally connected to the plate 22 at 51, engage between the plate 49 and a control sleeve 52. As the clutch engages, the movement to the right of the plate 22, due to the reaction, causes the plate 49 to move to the left, thus increasing the spring pressure. By moving the sleeve 52 from the intermediate position shown to the left so as, through the levers 50, to move the plate 22 to the right, the clutch can be disengaged at all speeds, while by allowing the sleeve 52 to move to the right the clutch will be engaged at all speeds. The plate 20 is caused to rotate with the plate 22 by pins 30 and the plate 22 is caused to rotate with the flywheel by the links 44 which pass through slots 45 in the plate. Specification 399,421 is referred to.

Title: Improvements in method of and apparatus for the manufacture of tiles and the like
IPC: B28B11/00
Filed: 1949-09-19
Abstract: 664,010. Moulding tiles &c. ATLAS PRODUCTS (OVERSEAS), Ltd. Sept. 19, 1949 [Sept. 29, 1948], No. 24044/49. Class 87(ii) A web 5 of cementitious material carried by travelling moulds 1 is cut into tile lengths by a knife 6 which moves along with the web as it moves down to cut it. After cutting, the knife is moved up and to the rear, to displace the material of the new leading edge of the web, to form the head check of the tile. The knife is then held stationary, relatively to the web, while a plunger 9 presses the displaced material to the desired shape, Fig. 6, between the knife and a bar 8 having a profile to fit the contour of the top surface of the web. The depth of the cut and consequently the amount of material displaced may be adjusted by a stop 34, Fig. 2. The moulds are carried on supports 2 mounted in an endless conveyer 3. The supports have projections, Fig. 8 (not shown), which engage pivoted triggers in a slide 21, to move the slide along with the web. The slide has an outer cradle 18 with rollers 19 engaging with fixed rails 20. The cradle moves with the slide by means of connecting links 21a. The cradle 18 has rods 17 on which slides an inner cradle 16. The knife is mounted on a bracket 14 connected by arms 15 to the cradle 16. As the slide 21 is moved to the left by the supports 2, a latch 7 is released by a striker 7a to allow the knife to be moved backwards, when a roller 25, Fig. 2, hits an abutment 26 causing toggle arms 24 to be straightened and thus pushing the cradle 16 along the rods 17. Simultaneously a roller 27 engages a ramp 28 thus causing the arm 15 to lift the knife flush with the top of the web. A roller 11a then engages a ramp 13 to cause the plunger to be forced down against a spring 9a. The rollers 19 then engage a ramp 20a to lift the bar 8 and the knife. A cut-away part 28a of the ramp 28 allows the knife to remain stationary relatively to the cradles- A similar ramp 13a allows the plunger 9' to rise under spring pressure. To smooth the upper surfaces of the material the plunger is simultaneously given a lateral movement by moving a shaft 11 axially. The plunger may similarly be given a lateral reciprocating movement before it is lifted. A ramp 28b then gives the knife a final lift to allow the latch 7 to be reengaged. The hinged triggers on the slide 21 are now disengaged from the projections on the mould supports by coming into contact with fixed wedges. The slide 21 is: returned to its original position by levers which are moved by projections on the mould supports and which are automatically disengaged when the slide reaches its original position. The cradle 16 is returned to its original position by a lever 32, Fig. 2. To prevent the bar 8 from spoiling the surface of the web on its return journey, auxiliary rollers 30 and corresponding rails 31 are provided to lift the right-hand end of the cradle 18. Australian Specification 105,651 is referred to.

A voltage comparator has the difference voltage (between E a  and E D ) applied to the base of a transistor TR1 whose emitter and collector are regeneratively coupled via a transformer T1, and a further transistor TR2 is emitter-coupled to TR1 for temperature compensation, gating pulses Up being applied to the emitters so that the transistors conduct and provide output pulses at A synchronized with the gating pulses, provided that the difference signal is large enough to initiate conduction in TR1. In the absence of gating pulses the emitters are biased positively through R6, D1, D2 and D3. Gating pulses cut off D1 and the emitters are then biased negatively through R7. The operating level can be varied by adjustment of R5 and/or R8. Temperature changes which would alter the conduction point of TR1 are compensated by a corresponding change in the emitter potential of TR2 which is communicated to the emitter of TR1. PNP transistors may be used instead of NPN.
