Filed: 1922-02-25
Abstract: 176,004. Bosch Akt.-Ges., R. Feb. 28, 1921, [Convention date]. Contacts.-Heavy-current switches are provided with fixed contacts 1, 2 bridged by a main brush 3 rigidly secured to the operating-rod 7. Auxiliary carbon sparking-contacts 4, 5 are secured in an annular conducting-ring 6 loosely mounted on the rod 7, an annular plate spring 8 being provided to press the ring 6 downwardly, acting at points 9, 9 in a line at right-angles to that joining the contacts 4, 5. Normally, the lower faces of the carbon contacts 4, 5 are sufficiently below the contacting edges of the brush 3 to ensure that the whole of the arc formed at break is taken by the contacts 4, 5, the shape of the disc 6 giving as large a radiating-surface as possible for the heat produced on breaking the current and the shape and relative disposition of the spring 8 preventing any excessive flow of heat thereto.

Title: Improvements relating to the froth flotation of cement raw material
Inventor: CLEEMANN JORGEN OLAV
IPC: B03D1/001
Filed: 1955-06-17
Abstract: In a process for froth flotation of cement raw material in a series of flotation cells with the addition of a frothing agent and a collecting agent either to every cell or to some only of the cells, the frothing agent is a water-soluble alcohol and it and the collecting agent needed at any stage are mixed in appropriate ratio and added as a single aqueous solution.  In an anionic process the collecting agent may be the alkali salt of a fatty acid and the ratio of frothing agent to collecting agent may lie between 1:3 and 1:30. Thus an aqueous solution may contain 0.4 per cent methyl isobutylcarbinol and 3 per cent sodium soap.  If cationic, the collecting agent may be an aliphatic amino salt and the above-mentioned ratio lie between 1:1 and 1:10, e.g. an aqueous solution having 1.5 per cent methyl isobutylcarbinol and 5 per cent laurylamine acetate.  The ratio of the agents may be varied according to the stage of the process, for example the proportion of frothing agent in the early part may be less than in the later stages; thus the alcohol in the above-specified solutions may be reduced respectively to 0.2 per cent and 1.0 per cent for treatment in the first two cells.  Depressants such as sodium silicate, starch, aluminium chloride may be added in the single solution of the invention, or separately.

Title: Improvements in or relating to the making of joints, terminations or repairs to electric cables
IPC: H02G1/14
Filed: 1942-12-12
Abstract: 561,162. Pliers. BRITISH INSULATED CABLES Ltd., WALTON, G. H., QUAYLE, J. C., and JONES, P. Dec. 12, 1942, Nos. 17695/42 and 13551/43. [Class 61 (ii)] [Also in Groups V, XI and XXXVI] A repair or joint in the thermoplastic insulation of a cable is effected by a pressure mould 2 having an electrode 3, which in association with a complementary electrode 4 of considerably greater extent which may be divided into two parts, is employed to subject the insulation to a high frequency electric field by which the insulation is heated, softened and united. The capacity between the electrode 3 and the cable conductor is considerably less than that between the conductor and electrode 4, so that most of the heat is generated in the joint. When part of the insulation 7, e.g. of polyvinyl chloride has been cut away, the gap 8 may be filled with additional insulation in strip form, or a longitudinally split section. In a cable joint a sleeve of insulation may be slid over the joint. Additional insulation may be omitted and the original covering brought into abutting or overlapping relationship , by stretching, involving a slight reduction of thickness at adjacent parts, which, if'desired, may be made up with additional material. The electrode 3 may form the internal surface of the mould or may be embedded completely in the mould. The mould may be provided with small channels to receive surplus material forced out. A cable jointing tool, Fig. 10, comprises a base 21 carrying the lower halves of a moulding electrode 23 and complementary electrodes 24. Pressure is applied to the upper halves of the electrodes by a hand lever 28 through arms 31. A switch is closed by the downward movement of the mould parts, and is re-opened after a predetermined closing movement of the mould. The switch may be as described in Specification 555,645. In Fig. 14, the complementary electrodes 26 are capable of movements towards one another. The mould parts 22, 25, are pressed together by a hand lever 28 -acting through a plunger 27. As the lever 28 is depressed, arm 31 causes rollers 45 to engage the electrodes 42 to grip the insulation and as it softens, to feed it into the mould. In Fig. 16, the mould is built up of helical lappings 55, of varnished cambric tape enclosing a tinfoil electrode 56, and exerts an elastic pressure on the joint. Alternatively, the electrode may be in the form of the jaws of a pair of pliers or tongs which grip the elastic mould, or which form the mould. A switch may be arranged between the handgrips of the tool.

Title: Concerning a cyclically operating container forming machine
IPC: C03B9/41
Filed: 1978-05-08
Abstract: The control device serves to increase the efficiency of a machine, which is subdivided into individual sections, for producing objects from glass. Each section has a shaping device (14). Each shaping device is assigned a section computer (13) which produces control signals for the shaping device (14) every working cycle of the machine as a function of a control program stored in a storage device (16) and of time switching values. The relative position of each working step within the working cycle is defined by a switch-on time and a switch-off time. These switching time values are stored in the section computer (13). The difference between the switch-on time value and switch-off time value is the dwell time available for carrying out the respective work step. This dwell time can be changed with the aid of a control console (21) by manual displacement of one or of both switching time values. The section computer (13) is programmed in such a way that it automatically prevents a change in the dwell time if a negative dwell time which is in practice not possible were to be produced by this change. <IMAGE>
