Title: Overhoist limit device for cranes
Inventor: COTTLE TERENCE STANLEY
IPC: B66C23/10
Filed: 1963-12-05
Abstract: 1,033,200. Overhoist prevention devices for jib cranes. STOTHERT & PITT Ltd. Nov. 2, 1964 [Dec. 6, 1963], No. 48173/63. Heading B8B. An over hoist limit device connected to the hydraulically driven hoist barrel of a luffing jib crane is arranged to stop the joist drive when the terminal fittings of the hoist rope reach a predetermined position beneath the jib nose and to start the hoist drive automatically in the lowering direction if the jib is subsequently luffed out. As shown, the hoist drum H drives a rotatable screw shaft 4 which is in engagement with a nut 1 in a guide 5. A lever 9 is connected at one end to a cable 14 which, when moved in the direction X against the action of a spring 17, actuates the hoist control to stop the hoist drive. The lever 9 is pivoted at 8<SP>1</SP> to a block 8 mounted in a guide 7, the position of the block along the guide being determined by the angular position of the jib J. One arm of a bellcrank lever 11 is connected by a link 10 to the block 8 and the other arm is connected by a link 24 to a lever 23 secured to a shaft 21 which extends through a bore in a fixed pin 20 pivotally supporting the jib and which is provided with a lever 22 secured to a bracket 22<SP>1</SP> on the jib. In operation, the hoist drum H rotates in the " hoist " direction until the nut 1 engages a roller 13 on the lever 9 and causes the lever to pull the cable 14 to stop the hoist drive. Subsequent luffing out of the jib causes the block 8 to move to the left causing the lever 9 to pivot about the roller 13, which is in contact with the nut 1, in an anticlockwise direction. This causes the inner member of the cable 14 to be pulled to the right causing the hoist drive to move through the neutral position to a " lower " direction.

Title: Improvements in or relating to Slack Adjusters for Disc Brakes
IPC: F16D65/56
Filed: 1967-11-01
Abstract: 1,185,858. Disc brakes. ALFRED TEVES G.m.b.H. 1 Nov., 1967 [27 Jan., 1967], No. 49654/67. Headings F2E and F2F. In or for a disc brake, a return spring 12 normally displaces a hollow piston 3 against a stop 10 on a pin 1 screwed into a caliper half 14. A further pin 17 projecting from pin 1 is resiliently biased against an inclined surface 16 of a sleeve 19 so as to provide automatic slack adjustment. As described, hydraulic fluid entering port 23 is arranged to displace the hollow piston 3 so as to engage a friction lining (not shown) against the disc. The return spring 12 is located between a cover 9 engaging a stop ring 10 and a cylinder 8 supported by a ring 2 against a circlip 4 within the piston 3. The sleeve 19 has three arms 20 (Fig. 2) and rests on a stop ring 11, spring 21 maintaining pin 10 in resilient contact with the 20-45 degrees inclined face 16. The screw 1 is normally adjusted manually by means of a tool-engaging slot 25 so that a gap S, corresponding to the brake clearance, exists between the lower side of arms 13 and ring 2. After the brake lining has become worn, application of brakes will cause the arms 13 to engage the ring 2 so that the engagement of pin 10 with the incline 16 will rotate the screw 1 so as to adjust the clearance. Radial grooves 26 may be formed in the arms 13 and the ring 2. Fig. 3 shows an alternative return spring 12a having ears 28 engaging the ring 2.

Title: Apparatus for controlling the rotary speed of a warp beam in a loom
IPC: D03D49/12
Filed: 1976-12-01
Abstract: 1517060 Warp let-off motions NUOVO PIGNONE SpA 1 Dec 1976 [11 Dec 1975] 50190/76 Heading DIE The rotary speed of a warp beam of a loom is controlled by a multi-ratio gear transmission 35, 36, 37, 38 the output 39 of which is connected to rotatably drive the warp beam and the input 30 is connected to be driven by a variable driven pulley 29 connected to be driven by a variable drive pulley 24 by a belt 28, the adjustment of the pulleys being controlled by a linkage 11, 14, 15, 20, 21, 34, 32 responsive to the tension in warp threads drawn from the warp beam. As shown, warp threads 3 are unwound from a metallic core 2 of the warp beam and pass over a drum 4 to the weaving station. The drum 4 is rotatably mounted on a rocker 11 carrying a block 13 fixed to a rod 14 pivoted to an arm 15 carrying a counterweight 19 for counterbalancing the tension of the warp threads. A link 20 connects the arm 15 to a bell-crank lever 21 which acts upon the movable flange 23 of the pulley 24 mounted on a shaft 25 driven from the mainshaft of the loom by a belt 26. The movable flange 31 of the pulley 29 is acted on by a bell-crank lever 32 connected by a link 34 to the lever 21. A spur gear wheel 35 is rotatable with the shaft 30 of the pulley 29 and meshes with a spur gear wheel 36 on a fixed idler shaft. A spur gear wheel 37 is integral and coaxial with the wheel 36 and meshes with a spur gear wheel 38 rotatable with a shaft 39 connected to the warp beam by meshing worms 40, 41 and meshing wheels 42, 43, the latter being coaxial with the warp beam 2. The wheels 35, 36, 37, 38 are mounted removably on their shafts so as to be interchangeable to obtain different gear ratios. In operation, the wheels 35, 36, 37, 38 are connected appropriately to set the desired rotary speed range of the warp beam. As the thread mass on the beam decreases, the speed at which the threads 3 are unwound tends to decrease and a tension increase occurs in the threads 3 which, acting on the drum 4, rotates the rocker 11 anticlockwise so that the arm 15 is lifted and the lever 21 is rotated anticlockwise to narrow the groove of the pulley 24 and the lever 32 is rotated clockwise to widen the groove of the pulley 29 to shift the V-belt 28 upwards and increase the angular speed of the pulley 29 to increase the angular speed of the beam 2 to its desired value.

Abstract: 1437246 FET inverter circuits; astable multivibrators INTERNATIONAL BUSINESS MACHINES CORP 7 Nov 1973 [29 Dec 1972] 51658/73 Heading H3T [Also in Division H2] An FET driver circuit chip comprises an FET driver 31 having its drain electrode connected to a voltage supply terminal and its gate electrode connected to a compensated voltage supply including an FET multivibrator 5-20 producing recurrent pulses having a pulse width directly proportional to the threshold voltage and inversely proportional to the transconductance of the FETs on the circuit chip and an FET circuit 23 providing the compensated voltage dependent upon the pulse width of the recurrent pulses. The multivibrator which is free-running may be constituted by cross-coupled FETs 5, 6 each associated with a similar delay line network formed by RC segments wherein the resistive elements are formed by FETs. As the FETs constituting the resistive elements provide the gain for charging the capacitors of the following segment, the amount of delay and hence the width of the recurrent pulses is a function of the FET transconductance and FET threshold voltage. FETs 9, 10 alter the conduction states of FETs 5, 6 at the end of each delay interval corresponding to the half-period of output pulses. A voltage multiplier circuit 23 includes a switch FET 22, a capacitor 24 and a load FET 25 for converting the recurrent pulses into a voltage which varies in a sense opposite to that of the variation of the output current of a driver circuit 30-35 with fluctuations of the FET transconductances and threshold voltages so that the driver circuit remains operating in a linear range.

Abstract: 1401869 Tractor power lifts MASSEYFERGUSON SERVICES NV 20 Nov 1972 [22 Nov 1971] 53568 72 Heading A1P A power lift system for a tractor is characterised by the method of measurement of draft load, consisting of a horizontal resilient beam 17 supported in fulcrum bearings 19 carried by a housing 15 attached to the tractor frame. The draft loads are applied to the beam 17 by a pair of lower links 5 through spherical bearings located just outside the fulcra and such loads cause the beam to bend elastically into an arc. The movement is not initially affected by the anti-rotation plates 20 which have elongated slots 24, nor by the recessed shafts 26 surrounding the free ends 21 of the shaft, since each recess has a radial clearance and merely provides a stop against excess movement clamped to one only of the ends 17a of the central part of the beam 17 is an elongated member 27 which otherwise has no contact with the shaft. At the other end of the beam is journalled a cam plate 33 carrying a pivoted link 37, which by endwise movement operates a hydraulic valve connected to the hydraulic drive to the tractor power lift. Spring 39 causes the link 37 to press downwards and maintain contact between the cam face 35 and the cam follower 31 carried on the free end of the elongated member 27. When the implement is clear of the ground, there will be compressive loads on the links 5 causing the resilient beam 17 to deflect in the opposite direction and the cam follower to move closer to the beam. In Fig. 5 the full line shows the cam in the no load condition, the dashed lines 32 the implement raised position and the dashed lines 34 the maximum draft force position.
