Title: Improvements in or relating to automatic voltage regulating equipment
IPC: G05B1/04
Filed: 1946-10-29
Abstract: 629,542. Automatic control systems for supply systems. STANDARD TELEPHONES & CABLES, Ltd., and KELLY, R. Oct. 29, 1946. Nos. 32042 and 36583. [Class 38 (iv)] In automatic voltage-regulating equipment for a power supply system comprising an electric regulating motor controlled by auxiliary relays operated from the " high voltage " and " low voltage " limit contacts of a marginal relay, if the auxiliary relays are operated simultaneously additional means cause the motor to either operate in a predetermined direction or stop. The invention is described in one embodiment with reference to an A.C. supply system in which a motor, which positions the tapping of the supply auto-transformer is controlled by two auxiliary relays, selected by a single marginal relay connected across the output; provision is made to prevent damage through the simultaneous operation of the auxiliary relays or the interruption of the supply to the control system. As shown, the tapping TC is positioned by motor MD1 to maintain the A.C. voltage at L2, N2 between limits. The motor MD1 and auxiliary relays HV, LV are supplied with A.C. through the fuses F3, F4 and the marginal relay with D.C. from the rectifiers W1. With a change in the voltage at L2, N2 beyond the limit values, the marginal relay JV selects one or other of relays HV, LV to cause motor MD1 to correct the position of TC. If either or both of fuses F3, F4 blow, the control system is rendered inoperative and no regulation occurs. If both auxiliary relays HV, LV are otherwise simultaneously operated, the contact hv3 is opened and the motor MD1 lowers the output voltage. A -similar contact may be included in series with hv1 so that upon simultaneous operation of HV and LV, the motor MD1 is disconnected. In a second embodiment a D.C. shunt motor which is connected directly across the supply to be stabilized, controls the regulation, and its direction of rotation is determined by auxiliary relays in the armature circuit which are operated by a marginal relay across the supply. Simultaneous operation of the auxiliary relays or failure of the fuses between the supply and the control system arrests control. Specifications 514,167, 514,294 and 515,948 are referred to.

IPC: C12N15/01
Filed: 1977-08-04
Abstract: 1535632 Producing poly-(3-hydroxybutyric acid) from bacteria AGROFERM AG 4 Aug 1977 [6 Aug 1976] 32783/77 Heading C3R [Also in Division C6] The invention is directed to a method of obtaining new bacterial strains (see Division C6) which are capable of producing microbiologically on a large scale poly-(D-3-hydroxybutyric acid) from cheap, abundant raw materials. The poly - (D - 3 - hydroxybutyric acid) obtained may be processed using conventional techniques to manufacture structures and moulded bodies such as threads, fibres and films which although resistant to acids, alkalis, light, air and most organic solvents, are biodegradable, e.g. in soil. The selected mutant strain is cultivated in the presence of the appropriate assimilable carbon source, such as glucose, fructose, sucrose, molasses, methanol, ethanol, glycerin, carbon dioxide and neutralized spent lye from caprolactam synthesis of specified composition, an assimilable nitrogen source material and trace elements, preferably in submerged culture, and the poly(D-3-hydroxybutyric acid) thus produced is isolated from the culture medium by extraction with polar or lipophilic solvents, e.g. ethanol, ethylene carbonate or propylene carbonate. The properties of the solvent largely determine the molecular weight of the poly-acid extracted. Molecular weights above 1,000,000 may be obtained by extracting with, e.g. propylene carbonate at 120 C. for 1-5 minutes. The extracted poly- (D-3-hydroxy butyric acid) may be subjected to intermolecular esterification to give poly-acid having an increased molecular weight.

Abstract: 875,657. Fabrics, testing and inspecting. MARVEL SPECIALTY CO. Sept. 28, 1959 [Sept. 29, 1958], No. 32824/59. Class 42 (2). A hosiery inspection and stacking machine includes a tube having a transfer passage extending from a hosiery inlet at one end to a hosiery outlet at the other end, a hosiery receiving form at the one end, means for causing air to flow from the outlet to the inlet to facilitate application of hosiery to the form, a stacking device movable along a path between the outlet and a stacking location and pneumatically operated means operated simultaneously with the air flow means to move the stacking device from the outlet to the stacking location whilst air is flowing in the said direction. In the arrangement shown a sock S to be inspected is placed by the machine operator on the inspection form 22. During this operation air is released from tank 40 along conduit 28 to the open end of the form 22 to facilitate the placing of the sock on the form. After the inspection, and assuming the sock to be satisfactory the operator depresses foot pedal FP which controls valves so as to stop the flow of air through the form 22 but to discharge air through the outlet opening at 30. This has the effect of creating a suction in the tube 28 such that the sock S is sucked down the tube and discharged into the retaining fingers 31. From the fingers 31 the sock is gripped by fingers 148, 150 and drawn out over the table T to be stacked thereon. The fingers 148, 150 are controlled by bellows 68 acting on the rod 94 connected to the assembly of parts constituting the stacking assembly generally indicated at 70. The bellows 68 is controlled in synchronism with the suction of the sock S from the form 22 and the tank 40 is charged from compressor 36 driven by motor 32.
