Title: Programming system with CRT and display unit
IPC: G06F3/048
Filed: 1982-03-02
Abstract: A programming system includes a CRT and a keyboard input device. The keyboard 3 contains usual numerical and command keys, and in addition contains data instruction keys especially for use in programming. The program, written using the keyboard 3 is displayed on the CRT 2 in ladder diagram format, may be converted and input to a programmable process controller 13.

Title: Flat knitting machine
Inventor: IRMSCHER HELMUT
IPC: D04B7/24
Filed: 1982-11-11
Abstract: To enable maximum knitting performance with minimum thread and needle loading in a flat knitting machine with a crank actuated needle drive and to allow a multiplicity of patterns to be realised in conjunction with simple adjustment of the knitting tightness and uncomplicated thread change operation, the machine comprises crank sheaves (10) which consist of circular wheels and toothed wheels and which are supported on shafts (15), the toothed wheels being driven by toothed drive sheaves. Each circular wheel has a pin (9) for moving a slide (7) which is mounted in a bed (20, 21) and connected with a rocker (5). The rocker is connected by way of a pin with a bedplate (6) and at its lower end with a foot (3) of a respective needle (2). The bedplates (6) have feet (22) which co-operate with guide elements (23) for needle selection. Each needle (2) has a further foot (4) for resetting of knitting tightness, the foot (4) being co- operable with a cam piece (26) fastened to a slide. A thread guide (48, 49) for each knitting system is selectable through cams (56). Synchronism between the thread guide movement and crank sheave drive takes place by means of a spindle drive (43) which is connected through a V-belt gear with a drive motor. <IMAGE>

Title: Conveyor for use with hopper wagon
Inventor: FRASER IAN RUSSELL
IPC: B65G67/24
Filed: 1983-04-19
Abstract: A mobile belt conveyor has a receiving tray (10) with collapsible or demountable side walls (11, 12, 13, 14) so that it can be inserted into the ground clearance space beneath a railway hopper wagon. The hopper can thus be discharged into the receiving tray of the conveyor instead of into a pit underneath the railway line. The need to provide such a pit is thereby eliminated, with a consequent reduction in capital cost, and there is increased flexibility in the positioning of the wagon for discharge, since it does not have to be positioned over a fixed pit. <IMAGE>

Title: Means for sealing a borehole
Inventor: HOFFMANN ERNST
IPC: E04G23/02
Filed: 1984-07-19
Abstract: A borehole closure 1 is proposed in which a tube 2 is clamped in a borehole opening by means of an inflatable hose 3 around the tube and sealingly secured to the tube at its ends. A grouting liquid supply connection 5 and a check valve 6 are provided at one end 25 of the tube and a closure 7 which opens in response to pressure in excess of a predetermined value and which includes a plastics ball 19 and a seat member 20 is provided at the other end 23 of the tube.

Title: A walking beam mechanism
Inventor: RICHMOND WILLIAM JAMES
IPC: H05K13/02
Filed: 1985-04-13
Abstract: A walking beam mechanism 20, such as for conveying roll pallets 16 in a vehicle 10, has a beam 32, 34 which is lifted by the interaction of rollers 38 with cam surfaces 40. The cam surfaces 40 have a first, steep, portion 46 and a second, shallow, portion 48 so that the beam 32, 34 is first lifted rapidly to an article-engaging height and is then lifted slowly to lift the articles 16 off the support surface. Only one end of the articles 16 is lifted, and the articles are dragged or pushed along by the lifted end. Preferably the end of the articles which is not lifted has wheels 28, and guide tracks 54 are provided on the support surface for the wheels 28 to run in. Fixed support means 30 support the lifted end of the articles when set down by the beam 32, 34 ensuring that any wheels 26 on the lifted end remain clear of the support surface. This provides a braking action to prevent rolling of wheeled articles when not lifted by the beam. <IMAGE>

Patent GB-2160138-A (GB)
Title: Cold pressure butt welding
Inventor: MITCHELL KEITH JAMES
IPC: B23K20/02
Filed: 1985-06-13
Abstract: Apparatus for end to end welding of two workpieces in a repeated cycle of operations comprises two carriers (10) each having a pair of jaws (D) for clamping around a respective workpiece and a drive mechanism (80-90) which reciprocates the carriers towards and away from each other. After the jaws grip each workpiece and the carriers move the workpieces together for butting pressure, detainers (40) acted on by a lost motion mechanism operated by the drive mechanism obstruct the movement of the jaws with the carriers when the carriers begin to move apart and a keyed connection thereupon moves the jaws of each pair apart transversely only to release the workpieces before the jaw pairs begin to retract axially with the carriers. Gates prevent return movement of the released workpieces but can be opened, as also can the jaws, to remove the welded workpieces and to insert fresh workpieces, by an additional retraction movement of the carriers. Operation of the drive mechanism is via a hand lever cranks and levers (18,87) or by fluid cylinders and levers. <IMAGE>

Title: Storage media transducer loading/unloading and carriage lock mechanism
Inventor: DALZIEL WARREN LEWIS
IPC: G11B21/12
Filed: 1986-06-16
Abstract: A transducer 16 is mounted on cantilevered beam 18 extending from carriage (20) which positions the transducer relative to the tracks on a magnetic hard disc 12, a hinged plate 30 selecting between working and idle conditions. A bevelled edge 40 of plate 30 lifts beam 18 to distance the transducer from the disc. Plate 30 also acts as a stop maintaining carriage 20 in its fully retracted position. When plate 30 is swung to the broken line position, the transducer drops onto the disc and the carriage is permitted to move in radially relative to the disc. The plate (30) is held in its two positions by a spring-loaded latch mechanism. A separation element formed by a rotatable cylinder with oblique angled surfaces may be provided. A plurality of transducers may be loaded/unloaded (Fig. 5), and the separator element may be operated by a trigger member (50) (Figs. 6, 7, 8) or solenoid operated pin. Rate of carriage movement may control rate of head loading/unloading. <IMAGE>
Patent GB-2198300-A (GB)
Title: Voltage-to-digital conversion
Inventor: KNIGHT PAUL ANTHONY
IPC: H03M1/00
Filed: 1986-12-03
Abstract: The power consumed by a load (1) supplied from a pair of a.c. supply terminals (2,3) is measured by repeatedly and cyclically connecting respective ends of a voltage sensing resistance (5) and respective ends (11,12) of a current sensing resistance (4) to the input of an analogue-to-digital converter (15) via a multiplexer (13). A microcomputer (7) subtracts the outputs of the converter (15) corresponding to the potentials on the ends of the resistance 5 from each other, as it does those corresponding to the potentials on the points 11 and 12, multiplies together each resulting pair of differences, and accumulates the results. In order to maintain those digital output words of the converter (15) which correspond to the voltage on one end (9) of the sensing resistance (5) in the middle of the converter output range, the microcomputer (7) generates the single most significant bits of these words on one of its outputs (75). These bits are fed back to the converter input via an integrator (95,96,97) to form a negative feedback loop. The resulting ramping of the converter input voltage also results in quantization errors introduced by the converter averaging out with time. <IMAGE>
