Title: Method of copolymerizing vinylidene chloride and vinyl chloride
IPC: C08F214/08
Filed: 1951-03-09
Abstract: Copolymers of vinylidene chloride and vinyl chloride are prepared by copolymerizing, in aqueous emulsion and in a closed vessel, a mixture of from 35 to 70 per cent of vinylidene chloride and from 65 to 30 per cent by weight of vinyl chloride, until from 10 to 60 per cent of the weight of mixed monomers has polymerized, as evidenced by a pressure increase at the substantially constant reaction temperature, of 2 to 12 pounds per sq. inch, then adding monomeric vinylidene chloride to bring the total ratio of polymerizing materials to a higher value in the range of from 65 to 95 per cent by weight of vinylidene chloride and 35 to 5 per cent by weight of vinyl chloride, continuing the polymerization until from 80 to 90 per cent by weight of the total monomeric charge is copolymerized, and then recovering the copolymeric product.  In examples polymerization is effected in the presence of dihexyl sodium sulphosuccinate, hydrogen peroxide and ferric nitrate at a pH of 2, and the latex coagulated in sodium chloride solution.  Other monomers such as acrylonitrile, acrylates, methacrylates, styrene and vinyl acetate may be present in minor amounts.  The polymers prepared by the process of the invention are particularly suitable for the production of films or filaments. Specifications 656,735 and 676,500 are referred to.

Title: Multiple ingot melting
Inventor: HOYLE GEOFFREY
IPC: C22B9/18
Filed: 1967-02-07
Abstract: 1,210,802. 802. Automatic control systems for electric furnaces. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Feb. 5, 1968 [Feb. 7, 1967], No 5813/67. Heading G3R. [Also in Division H5] In an electro-slag refining process a plurality of consumable electrodes are melted into one or more ingot moulds and a characteristic of the amount or rate of melting in respect of one or more of the electrodes is detected to produce a control signal to control the feed of all the electrodes in common at the same rate of feed. As shown three electrode clamps 15 are mounted on a common vertically movable electrode head 12 but are insulated from it by insulators 16. Three consumable electrodes 23 are held in the clamps 15 and depend into separate ingot moulds 11, the electrodes being maintained vertical by steady rollers 19 mounted on a bar 20. Each electrode is connected to one phase of a three phase supply the return conductor of which is connected to the bases of the moulds 11. The head 12 can be raised or lowered by the rotation of a threaded rod 21 which is driven by a motor 22 controlled by a controller MC acting in response to the current in one phase of the supply, this current being detected by a sensor CS and being characteristic of the rate of melting of the associated electrode. Thus the three electrodes are fed into the mould in common at the same rate of feed, consistent with the rate of electrode consumption as detected by the sensor CS. Individual variations in the electrode melting rates are self-compensating, since if an electrode starts to melt too quickly the working gap increases, the current falls and the melting is slowed down; the opposite occurs when the melting rate in any one phase slows down, and this makes it possible to control the feedrate by monitoring one phase only. Circuit breakers CB guard against overloads, and these may be linked to respective electrode clamps 15 which can be arranged to release an overloaded electrode from its mounting, the insulator 16 and head 12 then being designed so that the released electrode can pass there through as the feed of the other electrodes is continued.

Title: Improvements in electric switches or indicating devices
IPC: H02J13/00
Filed: 1929-02-22
Abstract: 329,678. General Electric Co., Ltd., and Angold, A. E. Feb. 22, 1920. Order and order-type apparatus. - An electric switch or indicator is linked to a number of levers having movable pivots so that it is moved one step when any lever is displaced, the steps being additive irrespective of the order of the displacements. The plungers 6 of the four coils 1 - - 4 are connected in pairs to links 8, 9, to the mid points of which is universally jointed a link 12, from the mid point of which is suspended an arm 13 which is pivoted to the plunger 32 of a coil 5. The arm 13 carries a contact-making part 16, which continuously engages a fixed contact 17, and is further formed with a part 36 adapted to engage one of a series of contacts 18 - - 21, 35 depending on how many coils are energized. Normally the links 8, 9 rest on arms 24 of a frame, but if a coil, say 1, is energized, the link 8 is rotated about its pivot with the plunger of the coil 2 and raised, and with it the link 12, so that the contact-member 36 is lifted into engagement with the contact 18. If, say the coil 3 is now energized, the lever 9 is similarly rotated, and the contact 36 is moved to engage the contact 19. If one of these coils is de-energized, the contact 36 falls back a contact, whereas if the coil 5 is energized, the arm 13 pulls on the link 12 and lifts the contact 36 through the distance of a contact. The position of the arm 13 with respect to the fixed contacts therefore depends on how many coils are energized, but is independent of such coils, or of the order of energization, or of the strength of current in the coils. An indicator device may be substituted for the contact 16, or the latter may give an indication. By varying the positions of the linkage joints, unequal movements may be given to the arm 13. The device is applicable also to the system described in Specification 261,844, [Class 38 (iv), Electric supply and transmission systems &c.], the coils being energized in accordance with the number of generators in operation and serving to select the several appropriate contacts of the underload and overload relays. The coil 5 and contact 35 are dispensed with in a modification, the arm 13 being pivoted to the frame.

Connected to the other arm of the lever 26 is a dash-pot 28 and a weight 30 which is integral with a link 31, suspended from a knife-edge on a lever 33. This lever 33 is fulcrumed on a bracket 35 and is connected at its other end through links 36 to a central knife-edge in a yoke 37, attached to the ends of which are the flexible ribbons of the pendulous resistants 40, 40. Pivotally mounted on the yoke 37 is a pointer 47, Fig. 1. The major divisions of the load are balanced by a slidable weight 21 on the steelyard 9, the position to which it should be moved being automatically indicated by the pointer 16. The minor divisions of the load are balanced by the pendulums 40, and indicated by the pointer 47. If the poise 21 is not in the correct position, the pointer 47 will then be at one extremity of its scale and hidden behind a shutter 55.
