Patent SE-310012-B (SE)
Inventor: FLOWERS T
IPC: H04Q11/04
Filed: 1962-05-30
Abstract: 1,034,924. Automatic exchange systems;. POSTMASTER GENERAL. June 1, 1962, No. 26177/64. Divided out of 1,034,921. Heading H4K. In a time division multiplex system comprising a co-ordinate array of cross-point switches for interconnecting incoming and outgoing multiplex trunks, each cross-point has an individual control circuit which under the influence of a set of (rectangular) pulses and a set of sawtooth pulses controls the closing and opening respectively of the switch during the relevant time slot. As shown, each trunk, comprising for example GO and RETURN highways 2, 3 together with their associated marking paths 1, 4, is multipled to a number of crosspoint switches, e.g. transistors 9 to 12 controlled by an individual circuit, e.g. NPN transistor 16. During the time slot allotted to a connection via the switch shown, a positive-going P pulse provided by circulating store 28 charges capacitor 23 so that eventually transistor 16 bottoms and thereby initiates conduction of the transistors 9 to 10 of the switch. The leading edge of each P pulse occurs when a sawtooth wave BP2 is at its minimum. Consequently, upon cessation of the P pulse, the rate at which capacitor 23 discharges into the base circuit of 16 is governed by the slope of BP2, the discharge terminating abruptly when BP2 reverses whereby transistor 16 and hence transistors 9 to 12 stop conducting.

Title: Microwave, RF, or AC/DC discharge assisted flame deposition of CVD diamond.
Inventor: ANTHONY THOMAS RICHARD
IPC: C23C16/26
Filed: 1992-10-09
Abstract: Broadly, the present invention is directed to improving a chemical vapor phase deposition (CVD) method for synthesis of diamond wherein a hydrocarbon/hydrogen gaseous mixture is subjected to a combustion flame in the presence of oxygen to at least partially decompose the gaseous mixture to form CVD diamond. The improvement in process comprises subjecting said combustion flame to one or more of dielectric heating, d.c. discharge, or a.c. discharge. Dielectric heating can be accomplished by subjecting the combustion flame to microwave (MW) frequency discharge or radiofrequency (RF) discharge. By superimposing dielectric heating or d.c./a.c. discharge plasma generation on combustion flame process, the carbon utilization rate of the combustion flame process should improve substantially. As noted above, given the low carbon utilization rate for combustion flame techniques already, small percentage improvements in the carbon utilization rates translate into substantial cost savings in generation of CVD diamond by such combustion flame technique. <IMAGE>

Title: Process for operation of a press-bending station for bending glass sheets
Inventor: FUNK DIETER
IPC: C03B35/24
Filed: 1995-04-12
Abstract: A method for operating a glass pane bending press, in automatic vehicle glazing mfr., involves: (a) lowering a bent glass pane, held by a vacuum holder below the male mould, by downward motion of the upper press crossbeam onto a shuttle ring held at a constant level above the female mould; (b) controlling the downward motion according to a velocity curve having an initial acceleration portion, a max. velocity section and a subsequent deceleration portion for gently laying the pane on the shuttle ring; and (c) designing the curve such that the first diversion of the curve progresses without singularities. The reduced pressure of the vacuum holder matches the pane wt. and the deceleration of the downward motion is adapted to this reduced pressure so that the vacuum holding force is always greater than the counter-force resulting from deceleration and such that the pane is not released from the male mould during deceleration. After redn. or switch-off of the reduced pressure, the pane is laid on the shuttle ring. <IMAGE>

Title: Transporting a liquid past a barrier
Inventor: FRAY DEREK JOHN
IPC: C25C3/02
Filed: 1988-03-29
Granted: 1992-01-02
Abstract: The invention provides a method of transporting a liquid A past or around a barrier, by adding a solute S to liquid A on one side of the barrier and correspondingly removing solute S from liquid A on the other side of the barrier, the solute S being such as to change the density of the liquid A when dissolving in it, thereby providing a motive force for its motion around the barrier. An example of the application of the invention is in a two-part electrolytic cell (1) comprising electrowinning and electrofining half cells (2 and 3, respectively), wherein the metal, solute S, is electrowon into a liquid (16,16a), liquid A, on one side of the cell's common electrode (4), the barrier, in the electrowinning half cell (2), and electrolytically removed from the liquid (17,17a) on the other side of the common electrode (4), in the electrorefining half cell (3).
