Abstract: 1,227,729. High voltage switches. S. & C. ELECTRIC CO. 17 Sept., 1969 [18 Oct., 1968], No. 45797/69. Heading H1N. A high voltage isolating switch, usable to reclose a circuit after it has been opened by an interrupter 10, is provided with means for inserting a resistance 53, 54 between its contacts before they engage so as to limit the inrush current. The switch may be of the kind described in Specification 1,091,643 with two contact blades 39, 42 attached to the upper ends of two rotatable insulator columns. The clamps 37, 45 for the contact blades are modified to carry two resistors 53, 54 to whose upper ends are attached a pair of blades 55, 56 with spaced arcing tips 59, 60. The blades 55, 56 are angularly offset from the contact blades 39, 42 so that the gap between them is smaller than between the contacts and the arc therefore strikes between the tips 59, 60 to insert the resistors in circuit before the contacts close; the blades 55, 56 are sufficiently spaced to prevent formation of ice between them in the closed position of the contacts.

Abstract: 1,234,339. Distillation of sea water; seacoast power plant. A. MAURIN. 16 May, 1969 [21 May, 1968], No. 25023/69. Heading B1B. [Also in Division C7] The duct CP, through which sea water is supplied to a seacoast steam power plant for cooling purposes, is protected against the deposition of organic material (e.g. algae) by adding to the sea water, as it flows through the duct, a chlorine-donating solution produced by passing the residual brine from the multi-stage evaporator 18..22 of a sea water distillation apparatus through cooler 25 into electrolytic cell 27. The electrolysed brine is mixed with sea water which has been electrolysed with iron electrodes in cell 39; and the mixture, which contains NaOCl and Fe<SP>++</SP> ions, is continuously or periodically withdrawn from tank 36 and injected at point 41 into duct CP. Sea water to be distilled is withdrawn from duct CP at point 1 and flows through heat-exchanger 6 where it is preheated by the cooling-water of Diesel engine 8. The sea water is then further heated by diphenyl oxide in heat-exchanger 9; and the hot sea water flows to evaporator 18. The steam leaving evaporator 22 flows through droplet-separator 28 to condenser 30, and the condensate is passed through ion-exchange resin battery 32, and may then be used in the boiler of the power plant. Diesel engine 8 drives alternator A which supplies power to the pumps and fans, and to the rectifier R which delivers d.c. to cells 27 and 29. In an alternative arrangement, the injection point 41 may be upstream of the point 1 where sea water for distillation is withdrawn from duct C.P.

Abstract: 1,238,112. Controlling motor vehicles. WHITE MOTOR CORP. 5 March, 1969 [7 March, 1968], No. 11794/69. Heading B7H. [Also in Division F1] A vehicle powered by an I.C. engine having a plurality of cylinders comprises means for venting at least some of the cylinders to atmosphere continuously during a braking period to a degree such as to cause the engine to operate as a compressor. Operation.-When switch 35, Fig. 5, is closed and switches 36 and 37 have been moved into their closed positions by a gear engaging movement of gear shift 42 and release of clutch pedal 40, the switch arm 22 is energized. Spring- loaded retraction of pedal 24 from its idling position causes the contact 28 to be engaged by arm 22 to energize solenoid 44 which actuates a valve 48 to terminate the fuel injection supply and create a light braking effect. In the 2nd position when arm 22 also engages contact 30 a solenoid 75 is energized which rotates eccentrics 70 to hold the exhaust valves 58 partially open thereby increasing the braking effect. In a 3rd position when arm 22 also engages contact 32 a solenoid 78 is energized to close a valve member 84 in the exhaust manifold to further increase the braking effect. The operation sequence of the solenoids 44, 75, 78 may be varied by changing the wiring of contacts 28, 30, 32. In other modifications the solenoid 78 may be omitted or brought into effect at the same time as solenoid 75. Operation of a switch 95 makes the gear shift switch 38 ineffective. Solenoid 44 may also control an ignition circuit.

Abstract: 1,265,935. Selective printing. BURROUGHS CORP. 6 Nov., 1970 [20 Nov., 1969], No. 52870/70. Heading B6F. Hammer mechanism comprises an inertial hammer 25, a solenoid 35, a pivoted actuator/ armature 27 and an adjustable backstop 29. The solenoid 35, when energized, attracts the actuator 27, and when de-energized, retains the actuator in contact therewith by residual magnetism. The hammer 25 continues in inertial flight to cause printing and on rebound strikes the actuator. This separates the actuator from the solenoid, and in so doing, the hammer loses kinetic energy. The actuator and hammer continue to the back-stop 29 which absorbs the remainder of the kinetic energy. The actuator 27 remains against the back-stop under the influence of spring 31 and the hammer 25 returns to its rest position under the influence of its leaf-spring supports 43. The hammer mechanism may comprise a single element moving along the print-line or form one of a plurality of elements, one for each character position. It is stated that the mechanism is suitable for a revolving drum or chain printer.

In Fig. 3 a plurality of specimen holders 4 are mounted on a specimen selector 2 which is rotatable in order to bring a desired specimen below the path 6 of the electron beam; the selector 2 is mounted on the specimen stage 1 which is movable in two directions normal to the beam 6. The electron detector 13 is suspended from a pair of rails 19 secured to the lower surface of a lens (not shown in Fig. 3) and carries a slotted guide 26 which is engaged by a pin 27 fixed to the stage 1; thus the detector follows movement of the stage 1 in the direction of the rails 19 but not movement in the orthogonal direction. The detector comprises a plastics scintillator 13 coupled by a flexible fibre optics bundle 31 to a photomultiplier (not shown), and the scintillator may be coated with aluminium which makes contact with a surrounding electrode maintained at a potential of 12 KV (Fig. 8, not shown). A grid 29 at a potential of 300-1000 volts is mounted in front of the detector and provides a suitable field for directing secondary electrons to the detector. In a modification, Fig. 2 (not shown), the detector is mounted directly on the specimen stage 1. The stage may be movable parallel to the beam to bring it to the focus of an optical microscope including optical mirrors for directing light on to the specimen and back into an eyepiece (Fig. 10, not shown).
