Abstract: 1,210,681. Injection moulding electrical connectors. JOSEPH LUCAS (INDUSTRIES)  Ltd. 1 Dec., 1967 [12 Dec., 1966], No. 55490/66. Heading B5A. [Also in Division H2] A connector unit forming part of a plug and socket connector is made by placing pins 11 crimped to leads 12 in a mould, injecting synthetic resin such as polyvinyl chloride around the pins, and allowing the resin to set. The pins are formed from a metal blank (Fig. 1, not shown) rolled into a tube, and the crimping serves also to close one end of the tube, minimizing the loss of resin. The moulded unit may include socket connectors 14 projecting from the flexible body 16 and encased only by individual sleeves 19 integral with the body. This construction is stated to provide adequate resilience of the sockets to allow for misalignment of the pins of a corresponding connector. The webs between the sleeves may be omitted.

Title: Arrangement for the rapid connection or disconnection of at least two power capacitors to or from an alternating-current main
IPC: H02J3/18
Filed: 1968-12-02
Abstract: 1,254,297. Capacitor switching arrangements for A.C. networks. LICENTIA PATENTVERWALTUNGS G.m.b.H. 2 Dec., 1968 [1 Dec., 1967], No. 57143/68. Heading H2H. The voltage drop or reactive current of a three phase A.C. supply system is compensated by the connection or disconnection or capacitors each of which is controlled by an anti-parallel pair of valves, one controlled and the other uncontrolled, the arrangement being such that the time to connect or disconnect all the capacitors is minimized and the neutral current flowing during the switching operation is reduced. These two effects are obtained by reversing the valve polarities in phase T relative to those in phases R, S and by switching the capacitors in the phase order RTS and at time intervals of 60 degrees. Transient oscillations during connection are prevented by firing the controlled valve at the instant when there is no or substantially no voltage across the valves as described in co-pending Specification 1,241,816 and Specification 1,250,356. A typical connecting operation is explained, Fig. 3 (not shown), and is compared with a similar operation using valve pairs all having the same polarity and switched in the phase order RST, Fig. 2 (not shown). Application of the invention to an A.C. system supplied from a star/delta transformer is described, Fig. 4 (not shown), which embodiment uses three groups of capacitors each connected in the manner of Fig. 1 and has appropriate polarity reversal between groups. The invention may also be applied to delta connected capacitors, with the valves inside the delta, to a single phase A.C. system using at least two capacitors and to other systems with an odd number of phases. Damping reactors #L are also provided.

Abstract: 1419260 Hydrocarbons; hydrocracking PIERREFITTE-AUBY 19 Dec 1972 [21 Dec 1971 24 Oct 1972] 58514/72 Heading C5E A hydrocarbon feed is cracked to olefines in the presence of hydrogen and in the absence of bromine at a pressure between 10 and 70 bars, a molar concentration of hydrogen not less than 20%, a reactor outlet temperature between 625‹ and 1000‹ C., and a residence time between 0À01 and 0À5 second. The feed may be a C 3  fraction, a C 4  fraction or a steam-cracked gasoline but is preferably low in aromatics. The hydrogen need not be pure, so long as the contaminants are inert or do not cause undesirable reactions. Steam may also be present as diluent. As shown, the feed is compressed at 1, mixed at 11 with hydrogen and cracked at 2. The products are separated at 3 into gas 4 and liquid 5, which are fractionated separately at 6 and 7. Methane, ethane, ethylene, propane and propylene are recovered as products from 6, or the ethane and propane fractions may go to an additional steam-cracker 8, the products from which are returned to the fractionator 6. Hydrogen from fractionator 6 is recycled. Heavy fractions from 6 are transferred to fractionator 7, whereas light fractions of the liquid 5 are transferred in the opposite direction. Fractions from the fractionator 7 may be taken off as products, e.g. for gasoline, used as quench at 15, recycled by line 13 or recracked at 14. Small proportions of sulphur in the feed as organic compounds or as H 2 S reduce coke formation. A build-up of aromatics should be avoided by taking off a suitable fraction, similar to coke-oven benzol at 7.

Abstract: 616,972. Furnaces. HOLDEN, A. DE F. Oct. 31, 1945, No. 28869. Convention date, April 5. [Class 51 (ii)] [Also in Group II] In a salt bath furnace, means are provided for cooling the upper part of the salt bath container so that any salt dripping over the edge of the container is frozen and seepage of salt over the outside of the container is thereby prevented. As shown, the cooling-means comprises a hollow ring 14 in which air for combustion in the burner is pre-heated. Air is admitted through the pipe 15 which is separated from the outlet pipe 16 by a baffle in the ring 14, to compel the air to make a circuit of the ring. Radial baffles projecting from the two vertical walls of the ring cause the air to follow a tortuous course and also produce turbulence in the air flow. The air pipe 16 is provided with valve-controlled branch pipes 24, 25 so that a regulable amount of fresh air can be admitted through the pipe 25 and a regulable amount of pre-heated air rejected through the pipe 24. The mouth of the container 4 is provided with a flange 18 which rests upon the top of the ring 14 the bottom of which rests upon the heatinsulating material surrounding the container. In a modification, the salt bath is heated electrically by immersed electrodes, the heat-insulating material being in contact with the outside of the container. Water, steam or other cooling-media may be circulated in the ring 14.
