Title: Control device for the stopper-rod of a foundry pouring vessel
IPC: B22D41/20
Filed: 1971-04-19
Abstract: 1329185 Stopper rod actuating devices PONT-A-MOUSSON SA 19 April 1971 [2 April 1970] 25074/71 Heading F4B A fluid motor V for controlling the movement of a stopper rod 3 in a metallurgical pouring vessel 1 comprises a double-acting piston 6 with a rod 10 connected by a cross member 11 to the stopper rod and a double-acting piston 5 forming an abutment for piston 6, with three -way electromagnetic valves 17, 18 and 19 controlling the supply of pressure fluid through pipes 12, 13 and 14. The piston-rod 10 is larger than a screwed rod 7 extending downwardly from piston 5 and having a nut 9 attached thereto. In operation, Fig. 1, valve 19 is on pressure, valves 17 and 18 being on discharge, the stopper rod 3 being thus held on its seating. Initially valve 19 is placed on discharge and valves 17 and 18 on pressure raising the rod through a distance x. Next valve 19 is placed on pressure and valve 18 on discharge raising the abutment piston 5 through the distance y i.e. until the nut 9 engages the bottom wall of cylinder 4. The piston 6 will move down to the abutment cylinder 5, but no further owing to the aforementioned difference between rods 7 and 10. This closes the stopper rod 3 to an operative position. In a modification (Fig. 4) valve 19 is replaced by a pressure reducing valve and valves 17 and 18 by a single four-way valve.

Abstract: 502,258. Dough - twisting machines. ALLEN, F. L. VAN. Sept. 21, 1937, No. 25613. Convention date, Sept. 21, 1936. [Class 87 (ii)] - Relates to a machine fur twisting the halves of a folded strip of dough or separate strips of dough around each other while simultaneously imparting torsion to the strips to prevent them from untwisting. A strip of dough is placed in two troughs 15, 15<1>, Figs. 3, 5 and 6, over a normally-fixed pin 41. The troughs are formed of a semicircular series of driven rollers to twist the halves of the strip in opposite directions. The troughs, shown in plan in Fig. 3, are mounted on a head rotatable about a vertical axis and provided with oppositely-rotating ribbed feed rollers 27, 27<1>. As the head rotates, it moves downwardly and twists the halves of the strip about the pin 41 in a sense opposite to that of the torsion of the strips effected by the rollers in the troughs. The ends of the folded twisted strip are pinched by fingers 130, 130<1>, and the pin 41 is with-, drawn. A wiper blade 109 or 1091 movable 'about a vertical pivot 116 and pivoted on an horizontal axis 119 or 119' is moved into a vertical position to receive the finished dough strip. The wiper blade then turns into an horizontal position to deposit the twisted dough strip on a conveyer &c.

[Also in Group XXXV] An electro-magnetically operated compressor for a refrigerator has two opposed pistons 16, 16' actuated by two vibrating spring blades 10, 10' carrying permanent magnets 13, 14 which are attracted and repelled by poles 38, 39 of two A.C. electromagnets, the whole compressor being resiliently supported by a centre plate 1, in a hermetically sealed casing 40. The lower part of the centre plate 1 carries two blocks 2 defining a single chamber 3 while the upper part carries two supports 11, 11a on which the two vibrating blades 10, 10<SP>1</SP> are mounted. At the free ends of blades 10, 10<SP>1</SP> magnets 13, 14 are clamped which in turn are connected to pistons 16, 16<SP>1</SP> respectively through members 15 and piano wires 17. When the coils 36, 37 are energised with A.C. the magnets 13, 14, which have opposite polarity relative to one another, are alternately attracted and repelled, thus causing the blades 10, 10' to oscillate and the pistons 16, 16' to move in opposite direction i.e. they compress the gas simultaneously in the respective cylinders 4, 4<SP>1</SP>. The movable units mounted on the vibrating blades 10, 10<SP>1</SP> have a natural period of vibration lower than that of the frequency of the mains. The outer ends of the cylinders are closed by caps 7 of flexible material through which the piano wire passes. In order to reduce demagnetisation of the magnets especially during starting the latter are at least partially embedded in electrically conductive non-magnetic material.

Abstract: 412,571. Frequency changing. AKT.- GES. BROWN, BOVERI, ET CIE., Baden, Switzerland. Sept. 26, 1932, No. 26720. Convention date, Sept. 25, 1931. [Class 38 (ii).] Alternating-current networks of different frequency and phase are coupled through a mercury-vapour converter, the control grids of which are suitably biassed from a single voltage source so that the magnitude and the direction of flow of energy can be regulated. A threephase network N1, Fig. 1, is connected to a single-phase network N2 through a converter G, the cathode K being connected to the midpoint of the secondary winding of the transformer T2. The grids are permanently connected through resistances to the negative pole of a battery M, Fig. 2, and are given at predetermined times a positive starting potential through distributers a, b, c having rotating brushes. The distributers a, b consist of contacts connected to the groups of grids. The brush of the distributer c rotates at a speed corresponding to the frequency of the network N2, and the brushes of the distributers a, b at a speed corresponding to the frequency of the network N1. Additional contacts are provided on the distributers to facilitate the transmission of the wattless power which can be regulated by displacing the contacts. The direction of the flow of energy is determined by the position of the contacts on the distributer c. In a modification, the distributers may be replaced by brushes A, B, Fig. 4, and a cylinder q which rotates at a speed corresponding to the frequency of the network N2 and carries a contact strip p through which the positive bias from the battery and a slip ring s is conducted to the grids. The contacts A, B are axially movable to facilitate regulation. In a further modification, the contacts A, B are mounted on cylinders which rotate at a speed corresponding to the slip frequency. In another modification the grids are not periodically biassed in accordance with the frequency of the network N1, and are connected through resistances, a transformer T3, Fig. 7, and a phase shifter U to the network N2. Control may be effected by hand or automatically, e.g. through governors, in dependence upon a day chart, the frequency or voltage of one of the networks or upon the slip frequency. Reference has been directed by the Comptroller to Specification 400,635.
