Title: Low leakage CMOS D/A converter
Inventor: BURTON DAVID PHILIP
IPC: H03M1/78
Filed: 1983-09-02
Abstract: The invention relates to the reduction of leakage current in a CMOS digital-to-analog converter of the type which comprises a plurality of switch-pairs (12A, 12B) in a common well (34), the individual switches of each pair being complementarily driven by switch drivers (30, 32) to "on" and "off" condition respectively to switch a corresponding terminal of a resistance network (R-2R) to one or the other of a pair of output lines in accordance with the state of an input bit, each switch having a driving gate and a back gate. Bias means is provided to develop a predetermined potential difference between the output lines and the well, with the well being more negative than the output lines, thereby to avoid bipolar leakage current. In one embodiment, the back gates of the CMOS switches (12A, 12B) are held at -200 mV with respect to the output lines, and the logic low level to the off switch also is set at -200 mV relative to the output lines. <IMAGE>

The indicator may be hidden when under tension and be released to move radially and/or circumferentially of the clamping device. <IMAGE>
Patent GB-2133502-A (GB)
Title: A valve for pressurized containers
Inventor: VAN DER SANDEN JOHN A
IPC: F17C13/04
Filed: 1983-11-29
Abstract: In a valve for pressurized containers, e.g. non-returnable compressed gas bottles, which prevents refilling of the container via the valve, a closure element 5 is during initial filling held away from these at 9 by a deformable ring 6. After filling closure element 5 is forced past ring 6 by plunger 8. Ring 6 deforms to allow the closure element 5 past but prevent its return. Closure element 5 is preferably biassed, e.g. by spring 7 or by magnetic attraction, against valve seat 9. On opening of a further valve 1, gas in the container urges closure elements away from seat 9. Any attempt to refill the container via nozzle 3 will cause closure element 5 to be urged against seat 9. The ring 6 may be integral with the valve body and seat. In other embodiments in which the closure element 5 has various different constructions (Figs. 9 to 11), it is deformable to enable it to pass ring 6. <IMAGE>

Title: Addressing liquid crystal cells
Inventor: AYLIFFE PETER JOHN
IPC: G02F1/133
Filed: 1985-04-03
Abstract: A method of addressing a matrix addressed ferroelectric liquid crystal cell is described that uses parallel entry of balanced bipolar data pulses on one set of electrodes to cooperate with serial entry of balanced bipolar strobe pulses on the other set of electrodes. The positive- and negative-going excursions of each data pulse are asymmetric, the excursion of one polarity having 'm' times the amplitude of the other and 1/m<th> the duration.

Title: Production of metal cans
Inventor: PORUCZNIK PAUL
IPC: B21D37/16
Filed: 1985-10-04
Abstract: In a die-ring assembly (10) for carrying out a drawing and wall ironing process, a coolant fluid is directed under pressure towards a metal can (14, 16, 24, 26, 28) as it passes through each work- performing die-ring (12, 18, 20, 22), said coolant fluid being directed at said metal can from a position (30A) disposed downstream of said die-ring or a position (30B) disposed upstream of said die-ring, or from both such positions, and said coolant fluid being directed in such manner as to create a vortex of coolant fluid swirling around the metal can. Downstream of each die-ring is a guide ring (12G, 18G, 20G, 22G) having a small radial clearance over the workpiece arriving from that die-ring. Downstream of each die-ring and before the next die-ring is a can punch damping ring (12P, 18P, 20P). Coolant fluid flowing over the can through said damping rings exerts hydrodynamic damping forces which tend to damp and restrain the can and punch (36) against transverse vibration. <IMAGE>
