Title: Device for resynchronising alternating current synchronous machines which have fallen out of step
IPC: H02J3/42
Filed: 1952-06-27
Abstract: 716,929. Syncronizing. AKT.-GES. BROWN, BOVERI, & CIE. June 27, 1952 [June 30, 1951], No. 16212/52. Class 38(4) Apparatus for resynchronizing a turboalternator 1 whilst. still connected to a supply network 4, comprises a reversible servo-motor 6 controlled over circuits 14, 15 and acting on the steam valve 2 of the turbine, through gearing 5, in such a sense as to restore synchronizm. An auxiliary machine 8, driven with the alternator and having its rotor excited from current transformers 7 in the output leads of the alternator, has a fixed stator electrically connected to the stator of a separate induction motor 9, the rotor of which carries an arm 9b for operating a switch 10 controlling the circuits 14, 15. Normally no current is induced in the stator of machine 8, so that motor 9 is unenergized and the circuits 14, 15 open. Upon the alternator falling out of synchronization, however, machine 8 delivers current at slip frequency to motor 9, which then rotates in a direction dependent on the direction of slip and operates switch 9 to close the appropriate control circuit 14, 15 to effect resynchronization. An overload trip relay 20 may be rendered inoperative during synchronization by a relay 17, responsive to completion of the circuits 14, 15, which effects shunting of the coil of the overload relay. The motor 9 may be braked by an eddy-current disc 21 and may be provided with electromagnets 11, 12 for ensuring positive action of the switch arm 9b at low values of slip.

Patent GB-402355-A (GB)
Title: Improvements in impulse transmitting apparatus for automatic telephony systems
IPC: H04M1/274
Filed: 1933-06-12
Abstract: 402,355. Impulse transmitters. BOYE, A., 141, Avenue Malakoff, Paris. June 12, 1933, No. 16774. Convention date, June 14, 1932. Addition to 381,532. [Class 40 (iv).] An impulse transmitter of the kind described in the parent Specification in which three selecting operations are necessary to effect the transmission of any desired seven-digit number of the form CEN 2334 comprises three cylinders 16i, 16c, 16u, bearing rows of projections corresponding respectively to the exchange codes, the hundred possible combinations of the first two numerical digits, and the hundred possible combinations of the second two numerical digits. The cylinders rotate in succession and each co-operates with a pair of slidable contacts 62, 63, Fig. 9, which by controlling a shortcircuit around the main impulse contacts serve to split the continuous train generated into the required digits. The depression of an external hand-lever 3 winds spring 1 and through a cam 39 removes a locking bar 34 from discs 24, 25, 26, and from the impulse cam 12. When the lever 3 is released the spring 1 drives shafts 22, 10,23, and the impulse cam 12. Cam 39 also acts on a pivoted lever 47, Fig. 6, to permit pawl 44i on the first cylinder to engage with ratchet wheel 36 so that this cylinder rotates with shaft 22 and the appropriate row of projections (52, 53, 54, Fig. 9) corresponding to the wanted exchange code acts by raising one of the spring contacts 62 from the bar 64 to open a normal shortcircuit around the impulse contacts 14. As soon as the code has been transmitted a tooth 68 on the last projection 54 acts on a suspended lever 67i to move a pivoted bar 70, Fig. 6, which stops cylinder 16i by withdrawing pawl 44i and starts cylinder 16c by engaging pawl 44c with ratchet wheel 37. The cylinder 16c is stopped and the cylinder 16u started and stopped in a similar manner. At the end of a complete cycle of the mechanism the locking bar 34 is restored owing to the engagement of a pin 43 with a flat-faced recess 40a in a controlling-cam 40. Contacts which short-circuit the transmitter and receiver when the apparatus is off-normal are closed by a hooked member attached to one of the locking arms 29 and are opened at the end of the final digit by the co-operation of the suspended lever 67u with a pivoted lever 81.

Title: High pressure polymerization of alkylcyclosiloxanes
IPC: C08G77/00
Filed: 1954-06-10
Abstract: Alkylcyclosiloxanes of the formula (RR1SiO)y, where R is an alkyl radical, R1 is a hydrogen atom or alkyl radical and y is an integer of 3 to 5, are converted to higher molecular weight polymers by subjecting them to a pressure of at least 1500 and preferably 15,000 to 100,000 lbs. per sq. in.  The process may be effected at 100 DEG to 350 DEG  C. and under static or continuous flow conditions.  The former process may be effected (1) by charging a reactor to maximum capacity with the cyclosiloxane, sealing and applying pressure by heating the charge, the reactor being provided with an automatic back pressure valve; or (2) by charging the siloxane into an open reactor and applying pressure on the charge by means of a hydraulic press or high pressure fluid intensifier.  The latter process is conducted in a heavy-walled tube-type reactor provided with heating means by maintaining positive flow through the reaction zone, pressure being applied by means of a high pressure plunger-type pump or by a hydraulic intensifier pump.  Examples are given in which the cylic diethyl trimer is polymerized.
