Abstract: 1,108,712. Drives for endless conveyers. RICHARD SUTCLIFFE ENGINEERING SYSTEMS Ltd., and L. BAINES. 1 March, 1966 [3 Dec., 1964], No. 49188/64. Heading B8A. [Also in Division F1] Each driving drum 4, 7, 8, 9 for a conveyer belt 1 comprises four hydraulic motors 12 at each end face of the drum, all the motors being fed from a  common line 14 supplied by a battery of hydraulic pumping sets 15 powered by electric motors 16. The drums act differentially and equally share the load when the conveyer is running. The return run of the belt 1 passes around the movable drum of a loop take-up carriage 11. Each drum may have its own supply, the pumping sets of the supplies being controlled by a servomechanism to match the outputs of the pumping sets to share the load equally between the driving drums. Driving drums, Figs. 3, 4 (not shown).-A shaft (21) rotatable in bearings (22) carries at each end a gear-wheel (25) driven by pinions (27) of the motors (12). Gear housings (26) are secured by torque arms (28) to a base-plate (23A). Fig. 4 illustrates how the hydraulic supply is distributed via an inlet block (30) and lines (32)-(35). The drum incorporates an hydraulically operable brake (29). Motors 12, Figs. 6, 7 (not shown).-A drive shaft (53) is secured to a a cylinder block (54) provided with five pistons (57) which engage cross-shafts (58). These shafts have end rollers (60) that engage a cam-track (61) formed around the inside of a casing (51). A floating pintle valve (62) extends into the hub (55) of the cylinder block (54) and is secured to an end plate (52) of the casing (51). In an alternative arrangement motors may be disposed inside a drum shell as described in Specification 780,729. Belt tensioning, Figs. 2, 5 (not shown)-A loop (41) in the return run of the belt (1) passes around a drum (40) supported by a carriage (11) which is movable in the direction of the belt 1 by a winch (42). A cable (43) forms a closed loop in passing from the winch around pulleys (not shown) on the carriage (11) and around a pulley (44) linked to a lever 45 also connected to an hydraulic reversing valve (47). A spring is disposed on a housing (46). At a predetermined belt tension hydraulic motors (13) which drive the winch (42) remain stationary. On increase or decrease of belt tension the pulley (44) moves so that the valve (47) permits the motors (13) to operate the winch (42) to pay out or take in cable.

Title: Resistance chain link welding machine
IPC: B21L19/00
Filed: 1969-10-07
Abstract: 1282478 Welding by pressure P ESSER [trading as MEYER ROTH & PASTOR] 7 Oct 1969 [9 Oct 1968] 49304/69 Heading B3R In apparatus for resistance welding chain links having a guide for the chain there is provided a saddle which moves relative to the guide to move a link between a pair of clamping tools to support the link during the welding operation. In one embodiment. Fig. 1, the downwards chain conveying movement of a conveying unit 16 can be made to lag relatively to that of the saddle 12 and travel at the same speed or can be made simultaneous and slower. The chain moves over a guide 13, 14, 15. In an alternative embodiment, Fig. 2, an entrainment element 24 is rigidly fixed to the slide 22 and an intermediate piston 25 reciprocates in a tongs housing 26 containing a tongs piston 27. When the slide is in the uppermost position pressure is applied via valves A, B, C to the upper side of the cylinder 20, the upper side of the piston 25 and to bias the tongs piston 27 into a clamping position, so that the slide 22 first moves down until the piston 25 abuts the tongs housing 26 which is then coupled with the slide 22 by the entrainment element 24. The valve 28 then changes to the control position B in order to lift the chain 19 via slide 22 and the return spring opens the tongs jaw 33. The upper limit of the slide 22 is set by an abutment 35. Embodiments are described, e.g. Fig. 3, wherein the tools for clamping the chain during welding are arranged so that one is mobile and the other is stationary. The guide 36, slide 37 and conveying unit (not shown) are adapted to move relative to the machine frame 39 by a system of levers 40, 41, as the mobile clamping tool 38 moves towards the stationary clamping tool. This sytem ensures that the chain reaches the stationary clamping tool at the same time as the mobile clamping tool contacts the chain. In another embodiment, Fig. 4 (not shown), two-arm rocking levers are employed so that a higher speed of the chain relatively to the mobile clamping tool can be obtained. In a further embodiment, Fig. 5, the chain and clamping tool 50 move at the same speed and are actuated by a spring 52 towards the fixed clamping tool 53 as far as the adjustable abutment 54 will allow. The abutment 54 is adjusted to abut at the time when the chain contacts the fixed clamping tool 53 and the entrainment element 56 then moves freely over the rod 51 for clamping. The maximum spacing between the clamping tool 50 and the chain 57 is adjusted by the abutment 58.

Abstract: 1406263 Substation equipment PIONEER ELECTRONIC CORP 6 Nov 1972 [6 Nov 1971] 51163/72 Heading H4K In a telephone answering machine, the time of each incoming call is recorded on the incoming message recording medium at the end of each message. A local speaking clock provides the time information. The time is recorded after the connection is released so as to minimize metering changes. In operation, ringing current on line 11 is detected by rectifier 12 so as to bring-up relays Y1 and Y3 after a short delay. Y1 connects an answering announcement on an endless loop tape T1 to line via an amplifier 15. A metal foil 18 on T1 short-circuits contacts 19 so as to bring-up Y2 which stops Tl's motor M1 and starts a motor M2 for driving an incoming message recording tape T2. The inertia of tape T1's driving capstan is such that the foil 18 clears the contacts 19 and the head H1 before the tape finally comes to rest. After a predetermined period timer 13 drops relay Y1 so as to clear the connection but Y3 temporarily remains up so as to permit head H4 to read-out the time from time clock 22 (which comprises an hours drum 221 and minutes drums 222, 223) on to tape T2. Finally Y3 drops out to restore the machine to its rest state.
