Abstract: 875,819. Moulding hollow or filled containers. RHENOPACK G.m.b.H. Sept. 3, 1957 [Sept. 3, 1956], No. 27710/57. Class 87(2). [Also in Group XVII] A hollow or filled container is moulded from a sheet of thermoplastic material, e.g. polyvinyl chloride, by taking a pre-folded sheet, a tube slit along its length or, as shown, a sheet 1 which is drawn from a reel 2 and folded by a head 3, heating the sheet by electric heaters 5, closing mould parts 6, 6<SP>1</SP> about the sheet and either blowing air under pressure through a nozzle 13, applying suction between the sheet and the mould parts or both or introducing the filling for the container, to force the sheet into contact with the mould. The mould may have ducts 12 to allow air to escape. The moulded container may be moved along either by the mould parts which move with the sheet or by holding device 8. With the latter arrangement several moulds may be used. The unsealed edges of the container may be sealed by welding and the containers separated and trimmed. The welding may take place in the mould, the mould being heated electrically or the material being heated by dielectric heating. The mould halves may be provided with an inscription or ornamentation or colouring matter.

Title: Improvements in and relating to electrically operated devices for transmitting motion to a distance
IPC: G01R13/00
Filed: 1933-10-10
Abstract: 431,850. Electric signalling systems. BOPP & REUTHER GES., 1, Carl Reutherstrasse, Waldhof, Mannheim, Germany. Oct. 10, 1933, No. 27915. Convention date, Oct. 10, 1932. [Class 40 (i)] For the distant transmission of pointer positions by means of an induction motor of the Ferraris type, two oppositely directed torques which act on a common shaft are respectively proportional to two currents, the values of which depend both on the position of the transmitter and that of the receiver, and are equal to one another only when the receiver and transmitter are in corresponding positions. Movement of a transmitter pointer q varies a resistance b to destroy the balance between the currents in opposed coils s1, s2, of the receiver motor which rotates its pointer p and varies a resistance c to rebalance the currents in the coils s1, s2, and stop the movement when the receiver and transmitter positions correspond. In an alternative arrangement the motor has two discs, co-operating respectively with the coils s1, s2. In a modification, Fig. 2, (not shown), for transmitting the sum, difference, or arithmetical mean of a number of measurements, the receiver motor has a single driving coil supplied from the secondary winding of a transformer provided with opposed primary windings energized in accordance with the positions of the transmitters and receiver. The variable resistances may be replaced by variable inductances or capacities, and the receiver may operate a recording device. Reference has been directed by the Comptroller to Specification 24855/98, [Class 40].

Filed: 1947-10-20
Abstract: 636,276. Regulating switches ; oil-break switches. SMIT & CO.'S TRANSFORMATORENFABRIEK N.V., W. Oct. 20, 1947, No. 27997. Convention date, Oct. 23. 1946. [Class 38 (v)] The tap-selector of a tap-changing switch is structurally combined with a circuit-breaker, such that as the selector moves over the tap contacts, the circuit is opened and closed by the breaker and not by the selector. Fig. 1 diagrammatically shows a selector 1 movable over bevel-ended contacts 3a ... 3c so as to close and open the breaker 2, respectively, after and before it engages and disengages the contacts 3a ... 3c. Figs. 10, 11 illustrate one phase of a transformer tap-changing switch comprising an oil-filled cylinder 8 carrying two rows of six contacts 3, the contacts 3 of the same potential being situated above each other and connected by strips 17. A further oilfilled cylinder 5 rotatably mounted by a bearing 11 in the cylinder 8 carries angularly-displaced circuit-breakers 1, 2, each having tap selector rollers 6 co-operating with a row of contacts 3. The contacts of the breakers 1, 2 are joined through connections 16 and a spiral resistor 4 on the cylinder 5, and the breaker 1 is connected to the outgoing line through further connections 16, collector 21, and contact ring 7. In a multi-phase switch, the breakers of each phase are mounted above each other, The arcing products of the circuit-breakers 1, 2 escape through vents 20 of the extinguishing chambers into the cylinder 5 and since the oil of this cylinder is separate from the oil of the cylinder 8, only the former oil requires periodic replacing. Further, the cylinder 5 together with the breakers 1, 2 and current collector 21 can be removed as a whole for inspection purposes. The Specification also describes the application of the invention to other arrangements of tapchanging switches and to selectors for duplicate bus-bars (Figs. 2-9, not shown). The Specification as open to inspection under Sect. 91 also included the subject-matter of Specification 636,312. This subject-matter does not appear in the Specification as accepted.
