Title: Improvements in or relating to multi-phase electric switches incorporating indicatormeans
Inventor: JACKS ERIC
IPC: H01H9/16
Filed: 1959-03-16
Abstract: 941,038. Snap-action switches; indicators for switches. ENGLISH ELECTRIC CO. Ltd. March 11, 1960 [March 16, 1959], No. 8939/59. Heading H2B. A multi-phase switch comprises fixed contacts 2 mounted within shrouds 3, each pair of contacts 2 may be bridged by members 4, secured to a common shaft 5 by insulating spacers 6. The shaft 5 is moved by a handle 7 acting through a quick make-and-break mechanism 8. An insulating sensing member 15 carried on arms 16 pivoted on screws 17 extends across the switch as shown, and is biased towards the bridging members 4 by a spring 19. One arm 16 carries a plate 20 having an L- shaped slot 21 co-operating with a pin 14 mounted on a crank-arm 13 which is journalled in the side of the casing. Arm 13 controls a quadrant or drum 11 having " ON and " OFF " legends alternatively visible through a window 10 in an indicator housing 9. When the switch is closed the arms 4 move member 15 and thereby rotate crank 13 to give an " ON " indication before the upper of the moving contacts engages the upper of the fixed contacts 2, and the remaining movement of members 4 is accommodated by the slot 21. When the switch is opened spring 19 returns the indicator to " OFF " unless one of the sets of moving contacts has broken away from the shaft 5, in which case the " ON " indication is maintained. An insulating barrier 22 is provided on the arm 16 which carries the plate 20 to minimize the possibility of flash-over from the contacts to the casing. The members 4 may be replaced by fuses and it is stated that the moving contacts may have a rectilinear instead of a swinging motion.

Title: Improvements in and relating to the injection moulding of plastic materials
IPC: B29C45/02
Filed: 1947-04-02
Abstract: 624,903. Injection-moulding. LONG, E. S. April 2, 1947, No. 8953. [Class 87 (ii)] Moulding material j, e.g. unvulcanized rubber or thermosetting or thermoplastic synthetic resin, is forced into mould cavities b in a block a by applying pressure to an imperforate plate k between which and a plate i, having apertures registering with the apertures d in a mcuid cover c, the material is placed. Excess material is retained between the plates i and k and can be recovered by removing these plates after releasing the pressure. The filled mould is removed to another heated or chilled press for vulcanizing,. curing or setting. The assembly of mould a and plates c, i and k is arranged to form a ram adapted to enter a cylinder h by upward movement of platen e actuated by a ram f of a press. On reaching the top of the cylinder further movement of the platen e &c. results in injection of the material k. Expulsion of the mould &c. from the cylinder is achieved by a plate l operated by a double acting ram m. The platen e may be heated by circulating fluid through bores g and the cylinder h may be heated or cooled as desired, e.g. by circulating water. The temperaturo of the apparatus is sufficiently low (for rubber and thermosetting materials) to preclude curing &c. during the injection. The injected material may be preheated before placing between the plates i and k. The press may operate downwardly to apply moulding pressure in which case the ram f carries the injection cylinder h.

Title: Esters of aromatic dicarboxylic acids
Inventor: CAVERHILL ALAN RYTON
IPC: C07C69/82
Filed: 1958-03-21
Abstract: Dimethyl esters of aromatic dicarboxylic acids are produced in a continuous process comprising two non-catalytic esterification stages; in stage (1) an aromatic dicarboxylic acid and methanol are passed concurrently through a reactor at a temperature above 240 DEG C., and in stage (2) the products from the first stage, from which products the esterification-water has been removed, are reacted with fresh methanol either in concurrent flow under the same temperature conditions as before, or in countercurrent flow at a temperature not exceeding 240 DEG C.  Both stages of the process may be carried out in a reactor consisting of narrow tubes, water and methanol being allowed to flash-off before the mixture, charged with fresh methanol, is passed to the second stage. Alternatively, the reaction-products from the first stage are allowed to flow down a bubble-cap column up which superheated methanol vapour at 220 DEG C. is passing.  An example relates to the production of dimethyl terephthalate. Specifications 578,079, 758,423 and 783,017 are referred to.

Title: Oven for treating iron ores
IPC: C21B13/06
Filed: 1924-04-10
Abstract: 234,951. Aarts, J. G. April 10, 1924. Extracting.-The charge supplied to an oven for the reduction of iron ore is conveyed through and over a series of superposed tables, plates or stories in counter - current to hot reducing gases and at a temperature which will not cause melting or fritting while the ore is changed into ironsponge. Iron ore, mixed with coal if required, supplied to the funnel e constantly drops through the mouth on to the circular stationary plates d and the annular plates b of the rotating mantle a. Teeth g on the underside of the plates rake the material so that it falls downwards slowly from layer to layer thus eliminating the usual very high furnace. Reducing gases supplied through ports i travel upwards at a temperature say below 1000‹ C. In the lower chamber l the hot ironsponge is carburetted, cooled or melted down with the aid of pressure air. The reduced ore is prevented from re-oxidation if desired by either carburetting in a reducing atmosphere by solid carbon or liquid hydrocarbons or else by melting in a reducing atmosphere.

Abstract: 902,675. Ski trainers. THOMAS, M. R. C. March 8, 1961 [March 16, 1960], No. 9236/60. Class 132 (1). A ski training appliance comprises a base having a ski-supporting surface and a pair of skis (real or imitation) adapted for free sliding movement over the supporting surface within the bounds of restraint imposed by elastic connections extending between the skis and the base. A plate A1 has an aperture for a ring B which projects slightly above the plate and over which moves a pair of skis F limited by springs or elastic cords G attached to a lateral frame H. The ring rotates on rollers D2 guided by lateral rollers D1. The rollers may be mounted in pairs on a block D supported beneath the plate. Springs and cords E are anchored to the ring by a connector B2 and to the plate by spaced posts A2 to limit rotation of the ring. A catch plate may lock the ring. The upper edge of the ring is roughened. Hinged legs of different height support the plate. Two ski sticks are anchored adjacent the track. Alternatively the ring rotates on rollers 2 mounted at each corner of a skeletal base 3 mounted on pivots 5 on pedestals 6. The skis 10 move over the ring each being constrained by a spring 12 connected to an adjustable swing yoke 13 pivoted on the base and by a cable 11 with springs 11A. The base rocks by means such as a linkage 8, 9 connected to a motor and reduction gear unit 7. In addition, or alternatively, two motordriven universally-jointed rods may connect beneath each ski. Webs 15 on the frame provide standing space when fastening the skis. The undersides of the skis may have facings of materials with different coefficients of friction.
