Title: Improvements in the processing of brewers' wort
Inventor: DUMMETT GEORGE ANTHONY
Filed: 1957-05-30
Abstract: In the continuous movement of brewer's wort from a mashing to a fermentation stage, the wort is passed to one or more vessels maintained at an internal pressure such, in relation to the temperature of the wort, as to cause flashing-off of certain constituents of the wort and such constituents are removed from the vessel to purify or concentrate the wort.  The flashed-off constituents can be collected and passed in indirect heat-exchange with wort passing to treatment.  The process can be included in the process described in Specification 848,641.

Abstract: <PICT:0920611/III/1> <PICT:0920611/III/2> In masking a commutator, in which insulating material 13 is shaped to provide intersegment recesses 16 between the segments 12, to prevent insulating composition entering the recesses when the windings of a rotor to which the commutator is fitted are impregnated with insulating composition a mask 17 comprising a water swollen film of regenerated cellulose is applied to the commutator to completely cover the recesses and the mask is dried to fit tightly thereon and engage the external parts of the commutator which lie around the periphery of the recesses.  The segments 12 and insulators 13 are embedded in a moulded synthetic resin core 3 carried on a metal sleeve 10 and a damp water swollen cap 17 of film produced by the viscose process is placed over the commutator so that cap portion 18 is in contact with the end of the commutator remote from commutator lugs 14.  The cap is dried in air at room temperature, in a current of warm air or by infra-red radiation and a second cap 19 is fitted over the first and similarly dried.  The caps which have apertures to allow the rotor shaft to pass therethrough shrink to grip the commutator tightly. The caps may be fitted without shaft apertures, these being provided by pushing the rotor shaft therethrough or by cutting away part of the caps.  After the commutator is fitted on the rotor shaft 21 the windings are impregnated by dipping the rotor in electrically insulating varnish and then placing it in a chamber which is evacuated.  Air is re-admitted to the chamber to force the varnish into the windings and on removal from the chamber the rotor is baked and the caps are stripped off or turned off in a lathe.

Filed: 1963-05-03
Abstract: 1,042,041. Automatic speed control. WELDING RESEARCH Inc. May 3, 1963 [May 4, 1962], No. 17514/63. Heading G3R. A D.C. motor 15 is supplied through rectifier bridge E-H and drives tachometer generator 14 whose output is compared with a reference voltage from potentiometer 12, the error voltage being applied to ring modulator A-D. The A.C. signal output from the modulator is amplified to operate servo motor 54 associated with potentiometer 61 the control voltage from which is combined with the original error voltage and applied to amplifier 60 which has a centre setting and conducts more or less, depending on the error and its direction. The amplifier 60 is coupled to switching circuit 80 controlling the phase of pulses applied to controlled rectifiers 111-114 which energize the motor. The circuit 80 is a balanced circuit with each branch comprising three transistors associated with pulsing transformers 105-108. By causing the branches of the control circuit to conduct more or less than half a cycle, the timing of the pulses is controlled to vary the motor current. The timing of the pulses may change the order of conduction to provide reverse rotation. The direct control by the error voltage to supplement the servo motor operation affords faster response. In another arrangement, the servo motor and potentiometer are replaced by an operational amplifier excited by a chopper having a vibrating contact which applies voltages thereto having polarities depending on the polarity of the error voltage.
