Abstract: 1,017,138. Actuation of circuit breakers; standby supply systems. CANADIAN WESTINGHOUSE CO. Ltd. March 24, 1964, No. 12384/64. Headings H2B and H2H. A transfer switch (Figs. 2A, 2B, not shown) for switching a load 14, 15, 16 from a normal supply 8, 9, 10 to a standby supply 11, 12, 13 upon failure of the former comprises a pair of circuit-breakers 6, 7 whose handles 45, 46 are operated simultaneously in opposite directions by slides 37, 38 mounted upon rods 39-42 and carrying roller assemblies 43, 44, the slides being driven by cam surfaces 35, 36 thereon engaging with followers 33, 34 mounted upon rotating gears 31, 32 driven by a further gear 30 from a unidirectionally rotating electric motor 19 with a one-way drive 49 or from a handle 18 which also carries a pointer to indicate the state of the switch. The gear 30 is arranged to be rotated through a half-revolution at a time, limit switch contacts being included in the breakers 6, 7. To assist in stopping the drive brakes, comprising spring-loaded cam surfaces 72, 73 engaging pins 68, 69 on gear 30, are provided. The motor 19 is controlled by a set of relays, all of which are shown in Fig. 3A in their deenergized condition. When the normal supply is present relays VR1, VR2, VR3 are energized through transformers 26, 27 to energize further relays TDNE, NR through normally closed contacts ER/1 closing contacts NR/3, NR/4 to supply current from additional windings of transformers 26, 27 to the motor 19 driving the transfer switch into the breaker 7 closed position. As it closes limit contacts NLS open to stop the motor; contact NS closes to light indicator 58. Upon failure of the normal supply 8, 9, 10 or any phase thereof relay NR drops out and after a delay so does TDNE; contacts NR/7, TDNE/1 are thus closed and a Diesel generator set is started to provide a supply 11, 12, 13 which is detected by a transformer 25 feeding a frequency sensitive relay FR which when the frequency is adequate energizes a relay ER closing ER/2 to re-energize the motor until the breaker 6 closes and limit contacts ELS open; ES closes to light a lamp 57 while lamp 58 has been extinguished. Upon reestablishment of the normal supply relays VR1, VR2, VR3 energize a relay TDEN which after a delay energizes the relays TDNE, NR to latter closing self-holding contacts NR/2, breaks the generator start circuit at NR/7 and re-energizes the motor as before. The motor can be prevented from operating by means of a latchable push-button 53 and a selector switch comprising the contacts designated SS/1-4 and a test push-button 65 are provided to initiate or prevent various functions of the system for test purposes. The transfer switch together with the various relays, transformers and bus-bars 8-16 are assembled on a switch-board.

Abstract: In a process for the homo- and co-polymerization of olefines of the formula CH2=CHR, in which R represents a hydrogen atom, an alkyl radical containing 1-5 carbon atoms or a phenyl radical, the polymerization catalyst used is formed by reacting (1) a titanium tetrahalide or a titanium trihalide prepared by the reduction of a titanium tetrahalide by means of hydrogen, aluminium, or an alkyl aluminium dihalide, with (2) a co-ordination compound prepared from an alkyl aluminium dihalide and an alkali metal halide or an alkaline earth metal halide.  In the examples homopolymers of propylene, butene-1, styrene, and 4-phenyl butene-1, and copolymers of propylene with ethylene or 4-phenyl butene-1 are prepared. Co-ordination compounds used are those formed by reacting ethyl aluminium dichloride with sodium chloride, potassium chloride, strontium chloride or barium chloride.  The polymerization is effected in an organic solvent and the polymers produced are isotactic.  The polymerization is terminated with n-butanol and the polymer is washed with water.ALSO:Co-ordination compounds, used as components of polymerization catalysts (see Division C3), are prepared by heating a mixture of ethyl aluminium dichloride with sodium, potassium strontium or barium chlorides.  They may also be prepared by reacting the alkali metal halide with the ethyl aluminium dihalide in solution in benzene and recovering the product from solution by evaporating off the solvent or by precipitation with an excess of an aliphatic solvent such as n-hexane or n-pentane.

[Class 110(iii)] Manual regulation of a steam-turbine and emergency stopping of the turbine at excessive speed or failure of the lubricating oil pressure are effected by a single set of four valves 29. The valves control the flow of steam from the chest 20 to the nozzle segments 28. The valves 29 have stems 31 of different lengths so that they are opened in sequence as the lifting plate 33'is raised. The plate is raised by a hand-operated gear 46 and a lever 37. The lever is pivoted between a stop 40 and the end of a rod 39 attached to a piston 48 which is kept in the position shown by pressure oil in a cylinder 49. The oil is supplied to the cylinder through two piston valves 53, 54. If the engine speed is excessive. as measured by a pump 56, the piston 53 rises. If the pressure of the lubricating oil fails the piston 54 falls. These movements shut off the pressure oil from the cylinder 49 and open the cylinder to waste. Downward movement of the rod 39 permits the valves 29 to close due to the weight of the parts 33 and 37.
