Title: Melt extrusion of plasticized acrylic polymer
IPC: D01D1/10
Filed: 1972-02-03
Abstract: 1337094 Semi-melt-spun acrylic fibres TOHO BESLON KK 3 Feb 1972 [6 March 1971] 5091/72 Heading B5B Fibres are semi-melt-spun from a powdered or granular acrylic polymer plasticized by containing 20 to 150% by weight of the plasticizer. In the spinning the polymer passes from a feed zone at a temperature below 100‹ C. to a melting zone at a temperature of 100‹ to 170‹ C. and thence via a vent zone to a compressing and measuring zone. In the vent zone the temperature is from 5‹ to 40‹ C. lower than in the melting zone and the pressure is reduced. This reduces the content of impurities volatile at the spinning temperature to less than 0À05% by weight, without volatilizing the plasticizer, and thus provides void-free fibres.

Title: Improvements in electrical power systems and control equipments therefor
IPC: H02P7/34
Filed: 1935-02-22
Abstract: 447,436. Control of D.C. motors. EASTWOOD, F. A., 46A, Poplar Grove, Brooklands, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Feb. 22, 1935, No. 5800. [Class 38 (iii)] Varying E.M.F. -In a system in which one or more motors are controlled by adjusting the field 12 of a generator 1 supplying them, the generator is driven by an alternating-current induction motor 4 having its stator windings arranged to provide two different pole numbers, and switching means 11, 17 are provided for changing from one pole number to the other and simultaneously reducing or increasing the excitation of the generator so that the generator voltage is maintained sufficiently constant during the change-over. The generator field 12 is regulated by a potentiometer resistance 13 having a pair of moving contacts 15, 16 mechanically connected together but displaced by an adjustable amount. With the switches 11, 17, in their lower positions and the contact 16 at the upper end of the resistance 13, a circuit 8 is energized to complete low speed connections for the motor 4, and the generator excitation is at a minimum so that the driving motors run at low speed. By downward movement of the contacts 15, 16, the speed of the driving motors is increased. When a certain point is reached the switches 11, 17 are thrown over so that the circuit 8 is de-energized and a circuit 9 energized to establish the high speed connections for the motor 4, the connection of the generator field 12 being changed simultaneously from the contact 16 to the contact 15. The reduction of the generator field strength thus effected, in conjunction with the increase of the speed of the motor 4, maintains substantially the same generator voltage. The driving motors are further controlled by further downward movement of the contacts 15, 16. The sequence of controlling operations is reversed for reducing the voltage applied to the driving motors. The time constant of the generator field circuit may correspond approximately to the period of time required by the motor-generator set to accelerate from one speed to the other. Specification 441,078 is referred to.

Title: Improvements in or relating to tuning control means for cavity resonators adapted tobe excited by electromagnetic waves
IPC: H01P7/06
Filed: 1943-05-26
Abstract: 599,700. Modulating apparatus cavity resonators. SPERRY GYROSCOPE CO., Inc. May 26, 1943, No. 6009/45. Convention date, May 27, 1942. Divided out of 599,672. [Classes 40 (iii) and 40 (v)] Tuning of a cavity resonator is modulated by a rotatable tuning element projecting within the cavity and adapted during part of its rotation to provide periodic variation of the resonator frequency and during another part to maintain the frequency constant. Amplitude modulation is thus provided of the highfrequency energy present in the cavity. As shown in Fig. 2, two such resonators are provided in a single structure, each comprising a cylindrical cavity 16, 17 and an axial stem 18, 19 integral with one of the end watts. The other end walls are slotted to receive rotary discs 8, 9 both on the same driving-Shaft 7, Fig. 6, and both having sinusoidal or other teeth 51 round one half of the periphery and a smooth rim on the other half. One set of teeth is of different pitch from the other and when one set is within the resonator, the other is outside. High-frequency energy is fed to the resonators by a concentric line 2 and loops 28, 29, and output energy is taken from each resonator to a corresponding aerial by pick-up loops 30, 31 and lines 10, 13. The whole may constitute an equi-signal beacon as described in Specification 599,672. As the points of the teeth, or the smooth part of the rim, approach closely to the stems 18, 19, the corresponding resonator is put out of tune with the highfrequency energy, and radiation is reduced or annulled. Preliminary tuning of the resonators may be effected by rotatable members 44, Fig. 3, adjustable by a screw-driver placed in a slot 45, and provided with a flat tongue 43, or a loop, projecting into the resonator cavity. Specification 523,712 also is referred to.

Filed: 1954-03-04
Abstract: 788,153. Refrigerating. HERON, A. G. April 26, 1955 [March 4, 1954], No. 6331/54. Class 29 Defrosting of a refrigerator evaporator by an electric heater DH is initiated by a time switch T and controlled by a two pole pressure switch EPS responsive to the refrigerant pressure in the evaporator and operative to stop defrosting by switching in the compression motor circuit and by passing the normal thermostat in such circuit. The compressor motor circuit, including a compressor P, pressure switch PC responsive to compressor pressure, and a thermostat CS controlling refrigerating cycles in the usual manner, is connected across the mains in parallel with the heater circuit, which includes the heater DH and a thermostat SH responsive to the surface temperature of the evaporator. Switches 1, 2 and 3, 4 are operated by a solenoid R, so that when the solenoid is de-energized the switch 1, 2 in the compressor circuit is closed and the switch 3, 4 in the heater circuit is open. The pressure switch FPS has its low pressure side 6 connected through the solenoid R and time switch T to the mains, and its high pressure side 7 to the compressor circuit between the thermostat CS and the pressure switch PS. In operation the time switch T closes and, the pressure switch EPS being normally at position 6, energizes the solenoid R thus cutting out the compressor P and starting the electric heater DH. When pressure inside the evaporator exceeds a predetermined value the pressure switch EPS switches to the high pressure position 7 de-energizing the solenoid R, starting the compressor P and stopping defrosting. This cycle continues until the timing switch T opens. Reference has been directed by the Comptroller to Specification 694,763.
