Title: Winch disconnect control arrangement
IPC: B66D1/16
Filed: 1976-04-28
Abstract: 1497852 Controlling winches; interlocking arrangements CATERPILLAR TRACTOR CO 28 April 1976 [11 July 1975] 17246/76 Heading B8B A control system for a winch cable drum 12 on a construction vehicle comprises a first control arrangement actuable by a lever 31 for selectively connecting the drum to a drive means in one of several modes and a second control arrangement actuable by a lever 54 for selectively actuating a disconnect clutch in the drive system, a retaining plate associated with the lever 54 preventing actuation of the lever 31 when the second control arrangement is actuated to interrupt the drive system. A power take-off shaft 13 from the vehicle drives the winch drum through a normally disengaged input clutch 14, gearing 15, 16, 18, one or other of two winch clutches depending on the direction of drum drive required and the normally engaged disconnect clutch. The control lever 31 on the vehicle operator platform may be moved in a gate between a neutral position in which the input clutch 14 is disengaged and the two winch clutches are engaged, a reel-out position in which the input clutch 14 is engaged with one winch clutch engaged and the other disengaged, a reel-in position in which the input clutch 14 is engaged with the one winch clutch disengaged and the other engaged, and a free-spool position in which the input and winch clutches are all disengaged allowing the drum to rotate freely. The retaining plate, movable upon actuation of the lever 54, is so shaped that it engages the lever 31 preventing complete movement of the lever 54 if the lever 31 is in its reel-in or reel-out position whereby the disconnect clutch cannot be disengaged. If the lever 31 is in its neutral or free spool position the lever 31 is respectively pushed into or held in its free spool position by the retaining plate once operated by the lever 31 operated to disengage the disconnect clutch. Both levers 31 and 54 are connected to linkages and cable which operate hydraulic spool valve for controlling the clutches.

Title: Improvements in or relating to the protection of shunt capacitor banks for alternating current lines
IPC: H02H7/16
Filed: 1957-05-31
Abstract: 812,672. Protective cut-out arrangements. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 31, 1957 [June 8, 1956], No. 17340/57. Class 38 (5). A star-connected three-phase series-parallel capacitor bank has an individual fuse 16 in series with each individual capacitor unit 14 of the bank, a voltage measuring network associated with each phase of the bank, means for adjusting the output of the networks and relay means responsive to the vector sum of the outputs of the networks. In the arrangement shown, the primary windings 30 of potential transformers are connected between the neutral conductor 18 of the capacitor bank and tappings 28 provided by auxiliary capacitors 22 series connected across each of the phases of the capacitor bank. The secondary winding 34 of each of the potential transformers has associated with it a variable resistance 42, capacitance 44 and inductance 46 which enable the output voltage to be adjusted to cornpensate for any initial unbalance in the capacitor bank. These output networks are connected in series with the primary winding 36 of a transformer. In the event of failure of one or more of the capacitors 14 causing its or their fuses to blow, the resulting unbalance causes the winding 36 to be energized and the current induced in the secondary winding closes a relay 54 to energize a time-delay relay 58 controlling a circuit-breaker trip coil 8. Alternatively, or in addition, the relays may energize signal lamps or an audible signal. Protective spark gaps 50 may be connected across the primary windings 30 and various modifications may be made in the relay circuit.

A machine for blow-moulding a hollow body having a side opening, comprises a frame 1, 3 carrying mould sections 2, between which an extruded tubular section 4 may be placed, and a blowing assembly having a tubular nozzle 26 which may be moved from one position to another to stretch the end of the tube before the mould sections are closed. The nozzle 26 is mounted by means of a disc 27 on a vertically adjustable hollow cylinder20, connected to a sleeve 14 which is hingedly connected to a rod 12 and is slidably mounted on guides 9. The other end of rod 12 is hingedly connected to a stopping lever 6. In operation the inclination of the nozzle is adjusted by disc 27 and the tubular section 4 is extruded until it contacts the lever 6. A pneumatic cylinder 16 then moves the member 14 and hence the nozzle 26 and the rod 12 along the guides. Movement of rod 12 pivots the stopping lever 6 outwardly. Thus the tubular section 4 is expanded to the transverse dimension of the mould. The mould sections are then closed and the body blown.

Abstract: 900,651. Cupping. PRODUCTION ENGINEERING RESEARCH ASSOCIATION OF GREAT BRITAIN, and HOWARD, F. Aug. 26, 1958 [June 1, 1957], No. 17466/57. Class 83 (4). A process for deep drawing of metal by the aid of a punch, a die and pressure exerted on the margin of the workpiece outside the die is characterized in that the pressure on the margin of the workpiece is substantially higher than the minimum necessary merely to ensure that buckling and wrinkling are avoided, while the workpiece is lubricated under fluid film lubrication conditions. The process is applicable to deep drawing nickel-chrome alloys, aluminium, stainless steel, mild steel and brass. The marginal pressure on the workpiece is 5 to 20 times the said minimum pressure. During the drawing operation the workpiece 11 takes a wedge-shaped cross-section with greatest thickness at the periphery 12 which forms a seal to confine the lubricant in pockets 18 and 19. Further seals are formed at 16 and 17. The lubricant may contain fatty acids, metallic soaps, extreme pressure ingredients such as sulphur or chlorine compounds or solid fillers, e.g. talc.

A pre-loaded roller bearing unit comprises main thrust races (1 and 4) having rollers (6) therebetween, a pre-load member (10), which is axially adjustable with respect to the race (1) to apply a desired amount of pre-load to the race (4), and a pre-load ball-thrust bearing (14) positioned between the race (4) and the preload member (10). The pre-load ball-thrust bearing (14) withstands the pre-load thrust only and not the main bearing thrust. The pre-load is applied by means of a bolt (19) which passes through a central bore (20) of the pre-load member (10) and is threaded into the thrust race (1), a head (22) of the bolt (19) being received in a counterbore (23) in the pre-load mem her (10). The race (1) has a central bore (9 which receives a spigot (12) of the pre-load member (10) and relative rotation is prevented by means of a key (11). The pre-load member (10) is stepped at (16) to receive the ball thrust bearing (14) and seals are provided between the races (1 and 4). When pre-loading is being applied, the bolt (19) is tightened while the race (4) is being rotated. When the required preloading is obtained, a locking-sleeve (24), having a hexagonal-shape bore therein, is fitted over the bolt-head (22). The locking-sleeve (24), having holes therein, is secured to the pre-load member 10, having tapped holes therein, by set-screws (25).
