Title: Driving system for continuous casting plants
Inventor: KRALL HERIBERT
IPC: B22D11/128
Filed: 1970-02-25
Abstract: 1,271,051. Continuous casting. SIEMENS A.G. 25 Feb., 1970, No. 9190/70. Heading B3F. [Also in Division G3] Apparatus for withdrawing the cast strand (2) from a continuous casting mould comprises withdrawal rolls (3) driven by an electrohydraulic stepping motor (5) and a pulse transmitting unit (4) electrically connected to the motor for programmed control of the latter. The casting is withdrawn intermittently and its direction of travel may be reversed for short periods of time to compensate for contraction of the strand. The nipping pressure of the rollers is varied in response to changes in torque occurring at the rollers, as is the transmission ratio between the motor and the rollers. Movement of the mould may also be effected by an electrohydraulic stepping motor, both of the motors being controlled by the same sequences of pulses through frequency dividers which enable any desired ratio of travel between the two motors to be maintained. The pulse transmitting unit may be controlled by means of punched cards according to a predetermined programme, or by a computer, which determines the required pulse sequences from operational data of the plant. Electronic means may also be provided for indicating metal and strand temperatures and for regulating the heating means for the molten metal and the cooling of the strand.

Title: Improvements in or relating to closing and tripping mechanisms for electric circuit-breakers
IPC: H01H3/30
Filed: 1951-04-20
Abstract: 709,930. Automatic circuit-breakers. ETABLISSEMENTS MERLIN & GERIN SOC. ANON. April 20, 1951 [May 3, 1950], No. 9291/51. Class 38(5) The closing-motor of the breaker is connected to the contacts over a crank and connecting-rod system, there being a mechanical lost-motion between the motor and the crank. The motor 5 drives a gear 8 and a cam 9 having a nose 10 which after a certain rotation engages a pawl 13 carried by a crank 12 which is loose on the gear shaft 11. The crank 12 is connected by rods 31, 15, 17 and cranks 14, 16 to a sleeve 19 connected to the contact bridge 25. When pawl 13 is engaged by the cam nose 10, crank 12 is rotated clockwise until it reaches the position 23a, where it is latched to hold the contacts closed, Fig. 3, by a lever 32, and the pawl hits a stop 24 to disengage it from the nose 10 which rotates through an angle and to enable the residual energy of the motor and flywheel 6 to be absorbed by means (not shown). When the lever 32 is tripped by hand or by a coil 33, the crank 12 is released and commences to turn counter-clockwise under the action of a spring 36. The sleeve 19 is thereby pushed down and eventually frees latches 34 from under a flange on a sleeve 26 carrying the bridge 25. The spring 21, which is compressed during the closing operation, is thus released and the sleeve 26 and bridge 25 rapidly move down to open the contacts, the sleeves 19, 26 resuming their normal relative positions at the end of the stroke. In a modification, Fig. 4a, the sleeve 26 has a hole 26a, with sloping edges and receiving a roller 28, which is also arranged to co-operate with recesses 37 in a rod 20 on which the sleeve 26 slides and in a member 27 arranged between the sleeves 19, 26 and connected to the latter by a spring 30. Movement of sleeve 19 downwardly from the " closed " position shown in Fig. 4a has no effect until it abuts the upper end of member 27 which is then also moved downwards. A downward force is thus exerted on sleeve 26 through the spring 30, this force being transferred to roller 28 by the upper inclined face of the hole 26a so that eventually the roller is forced to the right, into the recess 37 in member 27, Fig. 4c. This frees the sleeve 26 and the contact bridge which are thus moved down, as before, by the spring 21. The parts are restored to the Fig. 4a position when the contacts are reclosed.

Title: Processes for binding particulate solid materials
Inventor: EMBLEM HAROLD GARTON
IPC: C07F7/04
Filed: 1959-03-19
Abstract: Organic silicates containing Si-bonded aminoalkoxy radicals may be made by ester interchange from alkyl silicates (preferably of 1 to 5 C atoms) by replacement of some or all the alkyl radicals by aminoalkyl radicals, e.g. by refluxing the alkyl silicate (monomeric and/or polymeric) with a primary, secondary or tertiary aminoalcohol and distilling off the alkanols formed.  In typical Examples (1) tetraethyl silicate was refluxed with monoethanolamine to yield tetra-b -aminoethyl silicate; (2) a mixture of an ethyl silicate containing polysilicates and monoethanolamine was refluxed to yield an ethyl-b -aminoethyl silicate containing polysilicates and equal proportions of ethyl and b -aminoethyl groups; in other examples orthosilicates are made containing alkyl radicals and radicals derived from 2-amino-butan-1-ol, 3-amino-propan-1-ol, diethanolamine, triethanolamine and 2-amino-2-ethyl propan-1,3-diol.  The aminoalkyl silicates are mixed with finely divided refractories, e.g. silica, silica flint and sillimanite, shaped to the desired form, e.g. a shell mould, and the binder set by hydrolysis and gelation to silica gel (see Groups V and XXII).ALSO:A composition for making refractory moulds (see Group XXII) comprises a slurry of a particulate refractory material, e.g. silica, silica flint or sillimanite and, as binder therefor, an organic silicate (monomeric and/or polymeric) containing Si-bonded aminoalkoxy radicals (see Group IV(a)).  The binder is set by (hydrolysis and gelation to silica gel) by means of water which may be added to the composition prior to shaping or taken up from the atmosphere after shaping.  Examples are given.

Filed: 1962-03-13
Abstract: 976,108. Electric control of fluid-pressure brakes. WESTINGHOUSE BRAKE & SIGNAL CO.Ltd. Feb. 28, 1963 [March 13, 1962 ],No. 9619/62. Heading F2F. An electro-pneumatic braking apparatus for a rail vehicle includes a magnet valve having an application coil for connection to the application train wire 10 of the vehicle and a holding coil for connection to the holding train wire 11 of the vehicle the holding coil also being connected via a undirectional conductive device to the application control and the arrangement being such that in operation the holding coil may be energized independently of the application coil but on energizing the application coil the holding coil is also energized. In the Figure, vehicle units A and C of a train of vehicles carry control equipment consisting of switches 1, 2 and 5, 6 controlling brake application relays 3, 4 and 7, 8 respectively. Energization of relay 3 by closure of the switch 1 causes the positive terminal 9 of a current source to be connected to the application train wire 10 which together with the holding train wire 11 extends along the whole train. Energization of the relay 4 by closure of the switch 2 causes the positive terminal to be connected to the holding train wire 11. Similarly the source terminal 14 at the vehicle unit C is connected in the same way by operation of relays 7 and 8 to train wires 11 and 10 respectively. The magnet valve at A includes an application coil 15 connected through a rectifier 18 with the train wire 10 and two holding coils 16, 17 connected through a rectifier 19 and the train wire 11. The magnet valve at B is similar to that associated with A. However, the magnet valve at C has an application coil 25 connected to the train wire 10 and only a single holding coil 26 connected through a rectifier 28 to the holding train wire 11 and a further rectifier 29 forming the unidirectional conductive device connects the junction of coil 25 and rectifier 27. Energization of the application train wire 10 causes energization of application coils 15, 20 and 25 and holding coils 16, 21, 26. The rectifier 29 could be situated between the rectifier 27 and the train wire 10. It is thus possible to form a train of rail vehicles carrying electro-pneumatic braking apparatus in which the magnet valve of the apparatus has two holding coils intermixed with rail vehicles having electro-pneumatic braking apparatus in which the magnet valve comprises only a single holding coil.
