Abstract: 1362571 Pipe couplings SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 21 Sept 1971 [23 Sept 1970] 43948/71 Heading F2G On pressing rim 12 upwardly into sealing contact with a deformable sealing ring 52 in a gas container filling head the ring 52 is bulged outwardly on all sides to close narrow annular channel 100, so that the flow of fluid, via points 94 and 102, in an hydraulic or pneumatic control circuit for valve member 64, is blocked. The control circuit feeds compressed air to the space 78 above piston 76, in response to the blockage and this causes the valve member 64 to move downwardly away from valve seat 58 and against the action of return spring 86 and allow gas to pass into the container 10. The control circuit responds to lack of tightness at any part of the periphery of scaling member 52, by releasing the air from space 78, so that the valve member 64 is immediately closed. When the piston 76 is depressed, pin 104 opens the container valve 16. The filling head is resiliently mounted by resilient rings 34 and a centring sleeve has a plastics lining 44.

Abstract: 974,619. Packaging machines. ILLINOIS TOOL WORKS Inc. Dec. 22, 1960 [Dec. 24, 1959], No. 44094/60. Heading B8C. A machine picks up a succession of carriers at a supply station and applies them to containers, to form packs. Fig. 22, at an assembly station. The machine is duplicated as shown in Fig. 1, the containers 14 e.g. tin cans being fed from a supply 12 e.g. a can filling and closing machine, and separated by fixed guides 36 above a conveyer 34 into two pairs of parallel rows, each pair entering one machine. A handle is attached to each pack. Each machine has a roll 40 from which a web, Fig. 21, of carriers 18 interconnected at 28 is fed, Fig. 5, past guide roll 104, feed roll 102, guide bar 106 and a roll 108 on to carrier applying elements 48 on a rotor 50. The roll 108 has positioning pins 110. The elements comprise pairs of lips 70, Figs. 7, 10, slidably mounted on rods 76, 78. Blocks 80, 82 mounted on the rods 76, 78 respectively co-operate with cams 88, 90 to cause the lips of each pair to move away and approach each other once during each revolution of the rotor 50. The pairs of lips enter, in the close-up position, the apertures 22 and move apart to stretch the apertures sufficiently to allow them to pass over the cans. The withdrawal of the lips 70 after application of the web is facilitated by a stripper blade 154. The carriers are cupped as shown in Fig. 5 so that they lock under the beaded edge of the cans. This cupping is facilitated by a pair of fixed guide bars 130, Figs. 5, 10, which turn up the edges of the web. The interconnected cans are forwarded in a continuously moving stream below a carriage 184, Fig. 13, on which is mounted pack separating and handle applying means, the carriage being pivoted for temporary movement with the cans. The separating means consists of a member 204 comprising a head 206 mounted on a sleeve 208 and a knife 230 mounted on a rod 238. These are reciprocated by cam means (Fig. 13, not shown) to sever the stream into pack lengths, the head 206 entering apertures 30 to produce the desired spacing of the packs. Strips of interconnected handles 20, Fig. 18, are dropped from a magazine 282, Fig. 14, on to a conveyer 290 which forwards them along a support 292 to below a plunger 264. The plunger reciprocates to separate a handle from the strip and force the arrow-headed ends 254 down grooved guides 260, 262 and through apertures 32 in the carriers. A switch 293 having a feeler 295 senses the end of a strip of handles and operates a solenoid to drop a further strip. Specification 914,202 is referred to.

Title: Control circuit for the traction motor of an industrial truck

Filed: 1963-11-20
Abstract: 1,011,211. Control of D.C. motors. YALE & TOWNE Inc. Nov. 20, 1963 [Nov. 26, 1962], No. 45767/63. Heading H2J.  An industrial truck is driven by motor 7 which is supplied from a battery, the control system comprising a unit for supplying pulses to an oscillator producing a square wave with a variable duty cycle. The square wave is amplified to drive a power stage comprising parallelconnected transistors 87, 88. The motor current is maintained within a safe limit by varying the duty cycle of the oscillator. The pulse-generating unit comprises a transistor oscillator associated with a transformer with primary windings forming part of the oscillator circuit. The secondary windings have different turnratios to produce a plurality of output voltages, rectifiers being connected to the secondary windings to provide a plurality of direct voltages. One of the secondary windings is connected to terminals 37, 38 supplying negative pulses to the base of transistor 62, the arrival of a negative pulse causing transistor 62 to become conductive whereby transistor 74 is rendered non-conductive for a period determined by R.C. circuit 70, 71, 72. At the end of the delay period, transistor 74 returns to its conductive condition and transistor 62 is rendered non-conductive until the next negative pulse is received. Potentiometer 71 affords manual speed control of the motor. The square wave output signal from transistor 74 is developed across resistor 75 and is applied to transistors 75a, 76a for matching the high impedance output characteristic of the oscillator stage to the low impedance input of the power amplifier stage which comprises transistors 77, 78, for controlling the power traneistors 87, 88. A transformer 90 ensures that the paralleled transistors 87, 88 share the load equally. When the motor current exceeds a predetermined value, a signal derived from resistor 91 causes transistor 92 to be rendered non-conductive so that transistor 93 conducts, transistor 94 is cut off, and transistor 95 is made conductive to apply a positive pulse to the base of transistor 62. This shortens the duration of the output pulse from transistor 74 and decreases the average motor current. Diode 114 provides an alternative path for current-flow through the motor during the interval between pulses. Reversal is provided by field control, the current being automatically limited as described when reverse-current braking is attempted.
