Title: Apparatus for Severing and/or Sealing Thermoplastic Material, particularly bags
Inventor: WILSON ERNEST GEORGE
IPC: B29C65/74
Filed: 1965-06-26
Abstract: 1,155,565. Seaming non-metallic sheet material; cutting by a heated wire. ARISTOC Ltd. 24 June, 1966 [26 June, 1965]. No. 27176/65. Headings B5A and B5K. Apparatus for severing and/or sealing thermoplastic material, e.g. bags, comprises an electric conducting means, e.g. a wire 4, heated by passing an electric current therethrough and means responsive to the expansion of the wire 4 consequent upon being heated for limiting the temperature attained thereby. The wire 4 is stretched between arms 2, 5 pivoted about points 3, 6, respectively. The arm 2 is connected to a coil spring 1 and the movement thereof is limited by the length of the wire 4 and by an adjustable stop 7 limiting the movement of the arm 5. As the wire 4 expands the spring 1 moves the arm 2 so as to open a switch 53 to stop the supply of current to the wire 4. The stop 7 is adjustable to alter the longitudinal extension of the wire 4 necessary before the switch 53 is open to alter the temperature attained by the wire 4. The wire 4 is mounted on a head (not shown) movable vertically relative to a table on which a thermoplastic bag to be sealed is located and as the head is lowered adjacent to the table surface current is supplied to the wire 4. After sealing, as the wire 4 is raised, it is reheated to burn-off any thermoplastic material remaining thereon. A circuit for the operation is described, Fig. 1 (not shown). In a modification, Fig. 5 (not shown), two wires located mutually perpendicular to each other are provided to seal a bag along two mutually perpendicular axes. In further modifications, switching means prevents current passing through the wire after it has attained the correct working temperature with the head in the lowered position, automatic drop means is provided to hold the head in the lowered position until the severed material has cooled and been sealed, and, for the sealing a heavy gauge thermoplastic material, a rod, bar or a flat element on edge is provided.

Title: Process of shortstopping polyolefinic compounds
IPC: C08F2/38
Filed: 1954-09-23
Abstract: Further polymerization of polymers of olefinic compounds is inhibited by adding an alkali metal or ammonium trithiocarbonate. The short-stopper is preferably added to the latex immediately after the desired degree of polymerization has occurred, but it may be added as a dry powder, slurry or solution to the solid polymer.  Olefinic compounds referred to are butadiene, isoprene, dimethylbutadiene, chloroprene, cyanoprene and phenylbutadiene and mixtures with styrene, chlorostyrene, methylstyrene, 3,4-dichloromethyl-styrene, acrylic and methacrylic acids, amides, nitriles and esters such as methyl acrylate and methacrylate and ethyl methacrylate, and methylisopropenyl ketone.  Specified trithiocarbonates are those of sodium, potassium, lithium and ammonium, which may be used in conjunction with known short-stoppers, e.g. hydroquinone and alkali metal dimethyldithiocarbamates.  Examples describe the emulsion polymerization of butadiene-styrene mixtures at 41 DEG  and 122 DEG F. to 60 per cent conversion.

Title: Alkyl silicate binding compositions
IPC: C04B41/49
Filed: 1977-07-01
Abstract: The inorganic materials are treated with a bis-(trialkoxysilyl)-alkane, in particular bis-(triethoxysilyl)-ethane, and a hydrolysis catalyst, if appropriate in the presence of an agent which renders the inorganic materials water-repellent, expediently in an organic solvent. The silicon compounds used, having alkoxy groups, and their solutions in organic solvent are, with exclusion of water, storable virtually indefinitely even in the presence of a hydrolysis catalyst, show a relatively low vapour pressure and can be easily produced. In addition, bis-(trichlorosilyl)-ethane arises as a by-product in the preparation of vinyltrichlorosilane and can easily be converted by reaction with ethanol to bis-(triethoxysilyl)-ethane. The process according to the invention thus represents an advantageous possible use of a by-product which is otherwise difficult to utilise.

Title: Improvements relating to automatic control apparatus for stage conveyors and other moving mechanism
IPC: B65G23/00
Filed: 1945-10-25
Abstract: 600,524. Endless-belt conveyers. DAVIS & SON (DEBBY), Ltd., J., and DAVIS, W. H. Oct. 25, 1945, No. 28128. [Class 78 (i)] A coal face or similar conveyer having a number of separatelydriven sections has a control unit containing centrifugal governor mechanism associated with each section in such a way that, in the event of abnormal running of any section the driving of that section will be discontinued and, in succession, the driving of each section back to the coal face will be stopped. A spindle 12, Fig. 1, is geared to an idler pulley shaft rotated by the conveyer belt and carries a transverse spindle 25, Fig. 2, on which is mounted a governor weight 17. The spindle 12 is mounted in bearings 18, 19 at the end of a flame-proof casing 10 which contains switches A, B, C, Fig. 3. The switches A, B control the starter of the motor driving the next belt in the series, but the switch C breaks the circuit of the motor of its own section. Each switch has a spring-actuating blade 13 which is arranged to be depressed by a cam 14 carried by a block 15. This block is slidably mounted on the spindle 12 and on a guide 16. A slidable boss 20 having projecting trunnions 21 is secured by a spring ring to the inner member of the ball race in the block 15 and is connected by links 22 to the weight 17. A spring 28 is placed between the boss 20 and a shoulder on the spindle, A series of conveyers X, Y, Z, Fig. 4, is provided with control units X2, Y2 and starters X1, Y1, Z1 for the driving motors X3, Y3, Z3. If the belt X is put into operation by actuating the starter X1, when a certain speed is reached, the movement of the weight 17 in the unit X2 will have pulled the block 15 towards it a sufficient distance to cause the closing of the switches A, B, and consequently the actuation of the starter Y1. When the belt B attains a certain speed, the motor Z3 of the belt Z is started. If the belt Y, e.g. breaks or slips, the spindle 12 of the unit Y2 will stop or run slowly. In either case, the block 15 will move away from the weight and cause the actuation of the switch C to stop the motor Y3. At the same time the switches A, B are opened to stop the motor Z3. The long cables X4, Y4 connecting the control units and motor starters may be dispensed with if control units X5, Y5, Z5 are provided also at the motor end of each conveyer. The cams 14 may be arranged to operate other switches to actuate a warning light or indicator device to show which belt has broken down. Reference has been directed by the Comptroller to Specification 599,049.
