Abstract: 1,232,595. Gas blast switches; vacuum switches. ENGLISH ELECTRIC CO. Ltd. 21 Aug., 1968 [25 Aug., 1967], No. 39330/67. Heading H1N. A high voltage switch comprises a vacuum switch 15 and a resistor 14 in series with each other and in parallel with a main circuit interrupter 12, the vacuum switch 15 being normally open but being closed while the main interrupter contacts are being separated. The main interrupter and control arrangements are essentially as described in Specification 983,501. The movable contact 36 of the vacuum switch 15 is connected to a piston 43 subjected on one side to the pressure within the high pressure reservoir 20 through conduit 57 and on the other side to the pressure in the exhaust chamber 50 through a conduit 61. When the exhaust valve 49 opens in the usual way the pressure drops in space 50 and the vacuum switch closes. After the main contacts 22, 23 have separated the valve is reclosed and pressure rises in space 50, the vacuum switch being reopened by a spring 45, to interrupt the resistor current.

Abstract: 1,238,410. Coking liquid hydrocarbons. LUMMUS CO. 15 July, 1969 [15 July, 1968], No. 35606/69. Heading C5E. In a process for the delayed coking of a non- petroleum derived liquid hydrocarbon fraction, e.g. coal tar pitch, having a high content of condensed ring aromatics and an I.B.P. not less than 600‹ F., an overhead is recovered from the coking zone and a portion at least is recycled to a heating zone preceding the coking zone in a volume ratio in the range 0À3:1 to 0À6:1 based on the total feed (fresh and recycle) to the heating zone. The heating zone is operated at a temperature in the range 900‹ to 960‹ F., and the coking zone in the range 840‹ to 900‹ F., and turbulence is maintained in the heater, e.g. by introducing steam, to prevent premature coking. Before going to the heater, both the recycled and preheated fresh feed are delivered to a coker-combination-fractionater, where gases and vapours are flashed off, and a heavy oil (I.B.P. 600‹ to 750‹ F.) recovered and recycled, after cooling, to the fractionater.

Abstract: 1,265,201. Switch contacts. HUNDT & WEBER G.m.b.H. 7 March, 1969 [7 March, 1968], No. 12102/69. Heading H1N. A switch whose operating mechanism includes a first spring includes a second spring 7 resiliently biasing the movable contact 3 for firm engagement with the fixed contact 13 in the closed position, and damping means 9, 10 to damp vibration of the spring 7 when the movable contact 3 is brought into engagement with the fixed contact 13. As shown, movable contact 3 with contact tip 4 is mounted by a bracket 2 having a slot 5 engaging reduced portion 6 of a contact arm 1 moved by the switch operating mechanism (not shown) with spring 7 providing the resilience. The damping for the movable contact is provided by a cylinder 9, of a material having a high coefficient of friction, sliding in a cylinder 10, which has a split 11 and is gripped on to cylinder 9 by spring ring 12. Contact arm 1 bears on cylinder 9. Fixed contact 13 with contact tip 16 is also resiliently mounted by springs 15 and 20. Damping for this resilience is provided by shaping spring 20 in such a way that its free ends are bent and displaced so as to create friction. In a second embodiment, Fig. 2 (not shown), the movable contact is damped by a bolt 22, secured to movable contact 3 and slidable in an opening in arm 1, with a friction cylinder 23 secured around it sliding in two conical half shells 25 of friction material gripped on to cylinder 23 by the compression spring 7 which is cone shaped at its upper end. Bolt 22 is mounted on movable contact 3 so as to permit limited pivoting to enable the movable contact to orientate itself for good contact with the fixed contact. In a third embodiment, Fig. 3 (not shown), the movable contact is damped by an hydraulic cylinder. In a fourth embodiment, Fig. 4 (not shown), the movable contact is fastened to a contact arm comprising a set of leaf springs secured to an operating shaft. These springs 33 are supported in a stack at the shaft end, with spacers between them, and are clamped together in contact with each other at the contact end. The damping is caused by friction between the springs on relative movement during closure. To achieve the necessary high contact pressures, the springs 33 are prestressed.

Abstract: 1289444 Making welding dies TRIUMPH RADIO FREQUENCY Ltd 22 Feb 1971 5086/71 Heading B3A [Also in Division B5] A welding die suitable for use in a radio frequency welding machine comprises a rigid metal base-plate 1 having a slot 2 therein and a metal strip 3 received in the slot and extending perpendicularly from one face of the plate 1, opposite sides of the strip 3 being fixed to the plate 1 at opposite sides of the slot 2. The plate 1 and the strip 3 may be made of aluminium, aluminium alloy or brass, and the slot 2 and the strip 3 are curved. To make the die, the slot 2 is formed by a die sinker or end mill and the strip 3 is bent to the required curved shape, inserted into the slot 2 and pressed down so that the edge 4 thereof is flush with a face 5 of the plate 1. Two series of spot welds 6, 7 and weld seams are formed using gas or electric welding. The outer edge 6 of the strip 3 is machine finished and may be formed with a cutting edge to both cut and weld or form a tear-seal or may be formed with imitation stitch markings to form an embossed weld. In a modification (not shown) the weld metal joining the plate 1 to the strip 3 penetrates to the face 5. In an alternative method of making the die, the edge 4 of the strip 3 is positioned below the face 5 during welding and is subsequently made flush with the face 5. In use, the die is positioned between two platens in a radio frequency welding machine used, for example, to form motor vehicle trim panels.

On coin deposit and depression of a selector button, a solenoid 156 is energized and shifts an actuator 144 to the left, and this rotates clutch plate (128) relative to clutch plate 130 anticlockwise so that a driving element 142 thereon is shifted from the 5.00 o'clock to the 4.00 o'clock position. Simultaneously, a pin 160 on actuator 144 closes a motor start switch 116 which, through an eccentric plate (106), Fig. 3 (not shown) and arm (110) moves the bar 26 upwardly. An extension 120 of the bar rotates drive element 142 to rotate plate (128) counter-clockwise to the upper dotted line position. Plate 130 is rotated therewith through interengaging clutch teeth (136), Fig.9 (not shown). This rotates a shaft 126 and cams 162 thereon. The cam lug 162a engages the proximal cam ear 164 of one lifting unit 66 and rotates the lifting legs 68, (70) upwardly about an axis 64. The flipper 76 carried by the a bar 72 connecting the legs 68, (70) is also moved upwardly to elevate the end article. The flipper leg 86 then engages the upper edge of an opening 84 in the blocking member 32 and pivots about axis 72 to eject the end article. The next article is held back by retainer pins 90, (92) on the legs 68, (70) during return movement of parts 76, 68, (70) by springs 180. As bar 26 moves downwardly, a projection 124 thereon engages the drive element 142 and returns it to its initial position. Each support 24 has five lines of articles and five cams 162 72 degrees apart in sequential order so that articles are vended in sequence across each support 24. Each support 24 includes a member 170 that pivots when a line is empty to operate a sold-out switch 178.

The particles may be isomorphous with the desired polycrystallite and may be of fibrous or platelike shape. The final product may be a film or fibre. Specified inorganic solids, their precursors and suitable particles for incorporation are: alumina obtained via aluminium formate using alumina monohydrate particles (themselves derived by heating aluminium oxychloride under pressure); aluminium phosphate from aluminium chlorophosphate using silica fibrils or talc particles; titania from basic titanium chloride using titania particles; iron oxide from basic iron chloride using acicular #-Fe 2 O 3  or α-FeOOH particles; and silica from sodium silicate using silica or silicate fibrils. In typical examples the particles are dispersed in an aqueous solution of the precursor which is spun into filaments which are drawndown before wind up, followed by careful beating at a high temperature, e.g. 700-900C, to convert the filaments to the required product. Other materials useful as particles are listed, e.g. aluminium flake, potassium titanate and microcrystalline cellulose, which latter may be burned out of the final product to leave a purely inorganic matrix, e.g. of silica.
