Abstract: 1399700 Transformers MASCHINENFABRIK REINHAUSEN Gebr SCHEUBECK KG 19 June 1973 [20 June 1972] 28979/73 Heading HIT A transformer on-load tap-changing arrangement comprises output means L 1 -L 2  connectable to each of two input connections U 1 , U 2  through a main path I, II comprising at least two switches in series I 1 -I 2 , II 1 -II 2 , and an auxiliary path III, IV comprising at least two switches in series III 1 -III 2 , IV 1 -IV 2 . Each auxiliary path III, IV is connected to its respective input connection U 1 , U 2  via a switchover resistance Ri, R 2  comprising two resistors in series R 11 -R 12 , R 21 -R 22 ; and from the respective junction of each of these pairs a high resistance R 4 , R 5  is connected to the junction of two switches in the respective associated main switch path I, II. A further high resistance R 22 , R 21  connects a respective input connection U 1 , U 2  with the junction of two switches in the respective opposite auxiliary switch path IV, III. In the tap-changing sequences, e.g. from main path I to main path II, make-before-break switching occurs in the order I-III, III-IV, IV-II; any arc is self-extinguished at the first zero current passage after the opening of a switch. Each of the switchover resistances R 1 , R 2  is designed to drop a potential difference at nominal load current euqal to the step voltage (U 2 -U 1 ); and each resistor R 11 , R 12 , R 21 , R 22  is made equal to one-half its respective switchover resistance; in this way the recovery voltages of the switches in any path are made equal in magnitude.

Abstract: 442,384. Distributing music &c. STANDARD RADIO RELAY SERVICES, Ltd., Bush House, Aldwych, and ADORJAN, P., 13, Gledhow Gardens, Old Brompton Road, both in London. Oct. 10, 1934, No. 29006. [Class 40 (iv)] Distortion in a distribution system due to the high capacity of the connections between subscribers' reproducers and the feeders is reduced by the provision of step-down transformers between the feeders and subscribers connections. These transformers may replace the usual matching transformers associated with the reproducers. The invention permits a higher transmission voltage to be employed and a step-up transformer may be used at the input to the feeders. Where a number of subscribers' connections are close together a common transformer may be employed. The application to television distribution is mentioned.

Title: Improvements in and relating to automatically regulated change-over valves for bottled gas systems with two gas containers
IPC: F16K11/10
Filed: 1966-06-28
Abstract: 1,147,073. Valves. TEKNOVA A/S. 28 June, 1966 [1 July, 1965], No. 29008/66. Heading F2V. A change-over pressure regulator for bottled gas systems controls flow from two inlets 12a, 12b to a common outlet through similar valves 14. A spring-loaded diaphragm (3), Fig. 1 (not shown) which is responsive to pressure in the outlet chamber, acts through a lever (34), when this pressure falls, to move a plate 29 to the left. Journalled on a bent-over part 30 of the plate are two push rods 31a, 31b operative to lift the valves 14. A slot 28 in the plate slides on a pin 25 which is fast with a rotatable control knob carrying a pointer 22. Pin 25 is eccentric to the axis 17 of the knob and is biased by a hairpin spring 26 anchored at 27. In the position shown, inlet 12a is open and 12b is closed. This condition is indicated by the pointer on a scale portion 23a. On falling pressure, inlet 12a opens further and inlet 12b is also opened. This is indicated on a scale portion 23b. If the supply pressure at inlet 12a is restored the device returns to the first condition. If however this supply pressure is permanently exhausted, the knob is turned manually through about 180 degrees to bring the pointer against corresponding scale portions 23c, 23d, so that the regulation continues automatically with the valve of inlet 12b leading that at the other inlet in the opening direction. In a modification, Figs. 3 and 4 (not shown), the inlets are parallel and the diaphragm lever acts through a yoke (70).

IPC: B04B1/08
Filed: 1925-11-23
Abstract: 244,737. Aktiebolaget Separator. Dec. 19, 1924, [Convention date]. Density separators; discharging.-In centrifugal machines for purifying liquids and for discharging the purified liquids intovessels round the bowl, air which has passed through the vessels is prevented from streaming out into the room containing the machines thereby preventing the escape of dangerous vapours such as oil vapour. The bowl B has outlets C, D which open into collecting vessels E, F respectively, the oil in the case of oil purification being discharged into the vessel F. The outlet tube of this vessel is connected to a covered tank G above the surface of liquid in the tank; a pipe H connects the top of the tank to the outer air or with another room. The tank has also a liquid discharge pipe I. The liquid discharged from the drum outlet D mav be crude oil containing gasoline: some of the volatile components evaporate and are mixed with air while the liquid also contains finely divided air. This mixture passes to the tank G where the liquid separates out and the gaseous components pass away through the pipe H. To assist the movements of fluids, a fan K is attached to the bowl and rotates in the oil discharge chamber, its suction opening communicating with the slot be tween the bowl and the dividing wall of the vessels E, F. Wings J are provided to assist the flow of air. A vessel L at the top of the separator receives liquid supplied in excess of that necessary to fill the bowl. A condensing device may be arranged on the pipe H. In some cases the material discharged from the outlet D passes to the vessel M which revolves with the drum and leaves by openings N which are farther from the axis than is the outlet for the heavier liquid.
