Patent GB-773325-A (GB)
Title: Improvements relating to convertible organopolysiloxanes
Filed: 1954-11-15
Abstract: An organopolysiloxane convertible to the cured, solid, elastic state is subjected to a kneading action while simultaneously passing an inert gas therethrough to remove low molecular weight (below 500) siloxanes contained therein and boiling below 250 DEG  C. at 760 mm.. The convertible siloxanes used are well known and are disclosed in Specifications 594,481, [Group IV], 618,453. and 640,067 Inert gases specified are steam, air, nitrogen, neon and argon, and where steam is used, the siloxane must first be freed of any polymerization catalyst, e.g. by neutralization or washing.  The process may be effected in a Banbury mixer or a Baker-Perkins mixer having sigmatyped blades rotating in opposite directions and may be steam-heated to maintain a temperature, e.g. of 50 DEG  to 175 DEG C. during the kneading operation.  The inert gas is passed into the chamber above or below the mass being kneaded and the gas and volatiles are then led to a collection unit wherein the volatiles are condensed.  With air stripping recovery of the volatiles is effected by refrigeration or by an absorption process, whereas steam stripping merely involves condensation with subsequent separation of two liquids by decantation.  In examples: (1) a viscous methylpolysiloxane is freed of octamethylcyclotetra-, decamethylcyclopenta- and dodecamethylcyclohexasiloxanes by kneading in a mixer into which air or steam is passed; and (2) air or steam stripping is compared with vacuum stripping.  Specifications 768,286 and 773,324 also are referred to.

Abstract: 1,099,671. Control of A.C. motors. ENGLISH ELECTRIC CO. Ltd. Aug. 20, 1964 [Aug. 23, 1963], No. 33408/63. Heading H2J. [Also in Division G3] A signal representing the desired torque of an induction motor is developed across potentiometer 21, and a signal which increases at a progressively increasing rate with increase of speed is produced on line 23 which is associated with non-linear amplifier 24 receiving an input signal on line 25 which is proportional to the speed of the motor. The torque reference signal and the speed signal are added by amplifier 19 for adjusting the rotor resistance so as to maintain the torque substantially at the desired value for varying speeds. Each section of the rotor resistance is controlled by a contactor 17 connected with a switching amplifier 18, the values of the resistors being related according to the geometrical progression, the resistor corresponding with the contactor 8 having the highest value. The magnitudes of the control signal from the amplifier 19 required to operate the rotor contactors in sequence are related in accordance with an arithmetical progression. the contactor 8 being the first to close. The stator winding of the motor may be energized with direct-current for braking and the characteristic of the amplifier 24 modified so that the signal on line 23 increases at a progressively increasing rate with decrease in speed. The input on line 20 may represent the deviation between the desired and actual speeds, and the system so adapted for closed-loop control. Direct-current braking operation is introduced automatically when the speed feed-back signal exceeds the reference signal. In a modification the rotor resistance is of the liquid type with a non-linear relationship between the control signal from amplifier 19 and the actual resistance between the electrodes. This relationship is such that the resistance decreases at a progressively decreasing rate with increasing control signal, Fig. 4 (not shown).
