Title: Polymerization process
IPC: A63B37/00
Filed: 1962-06-14
Abstract: Polymers of conjugated dienes of high trans-1,4 configuration are made by polymerizing the dienes in the presence of a catalyst system consisting of an organometallic compound of lithium, or a metal of Group II of the Periodic Table, an iodine-containing compound of titanium, zirconium, hafnium, or thorium, and a thioether.  The organo-metallic compound may be methyl, ethyl, butyl, amyl, or dodecyl lithium, methylene dilithium, ethylene dilithium, hexamethylene dilithium, allyl, methallyl, phenyl, tolyl, naphthyl, or 1,4-dilithium benzene, butadienyl lithium, dimethyl, diethyl, di-n-butyl, or di-n-octyl zinc, or the corresponding compounds of mercury, magnesium, cadmium, or beryllium, or a magnesium Grignard-type compound.  Specified thioethers are dimethyl, diethyl, di-n-propyl, diisopropyl, di-n-butyl, and dioctyl sulphide, methylethyl sulphide, isopropylethyl sulphide, isopropyl-methyl sulphide, and isopropylbutyl sulphide. The iodine-containing compound may be TiI4, TiCl3I, TiCl2I2, TiCl3I, TiI3Br, TiI2Br2, TiIBr3, TiCl2I-(C2H5), TiClI2 (C2H5), titanium monoiodotriacetate, diiododipropionate, triiodomonobutyrate, monoiodotrioxalate, triiodomonoacetate, monochlorodiiodomonoacetate, or monochloromoniododiacetate, or triiodomonoethyl, or di-iododibutyl, or monoiodotributyl, or dichloromonoiodomonobutyl titanate. The diene may be butadiene or isoprene.  The polymerization is effected in an inert hydrocarbon diluent, and terminated by the addition of an alcohol.

Title: Off-line magnetic card reader system operable as though normally on-line
IPC: G07C9/00
Filed: 1976-06-04
Abstract: 1512896 Magnetic card reading and door-controlling system A & T-O INC 4 June 1976 [17 June 1975] 23091/76 Heading E2A [Also in Division G4] Magnetic card reader for operating a door or the like has on-line sensors connected to a processor which verifies data and operates the door and off-line sensors which are capable of supplying data to release the door if the processor is inoperative. The card 10 is inserted in a reader and operates a card detection switch 18. The card is spot magnetised in an area detected by on-line sensors 12 and in an area detected by off-line sensors 14. The sensors have coils which are pulsed and the decay of the pulse determines whether the spot is magnetised or not. Sensors 12 are pulsed by network 20 and data is fed to console 22 when the station is queried by the console. The console is connected to a plurality of the networks. If the card data matches stored data a go command releases the door. Normally gate 34 is conditioned to supply query and command pulses from the console 22 by timer 40 which is reset by each query pulse so that the networks can be queried and a flip-flop 26 can be set to operate network 28. If signals do not appear from the the console the timer at the end of its period conditions gate 34 to pass data from network 52 which receives data from the off-line sensors. Data fed from sensors 14 is fed to buffer 48 which may be a shift register and a circuit 50 determines whether the data corresponds to any of the predetermined set of data. Network 52 supplies go or no-go pulses to the gate 34 which control the flip-flop 26.

Title: Mould-in hinge member for spectacle rims
IPC: E05D9/00
Filed: 1977-06-01
Abstract: The anchoring part (1, 2), which is to be inserted into the plastic, of a hinge eye (4) has an edge shoulder (2) which projects in the height direction parallel to the axis of rotation. In the direction from the axis to the anchoring part (1, 2), the centre part hinge consisting of the hinge eye with the anchoring part firstly has a reduced width and then, thereupon, a parallel shoulder (6) having the same width as the hinge eye (4). The centre part hinge widens on the boundary, adjacent thereto, with the anchoring part (1, 2) in height and width in a step which serves as sealing surface during injection. The edge shoulder (2) follows as the second step. During the injection process in the injection mould, the special shape of the hinge takes account of the seals required for the high pressures which occur, and effective anchoring of the anchoring part (1, 2) in the injection material is achieved. <IMAGE>

For this purpose, the sprung holding device (10, 15) is electrically insulated from the mesh cathode (1), and a second cathode lead (12) extends into the inside of the mesh cathode (1). The second cathode lead (12) surrounds the sprung holding device (10, 15) coaxially, and at the other end it has a flexible, electrically conducting connection to the mesh cathode (1). This electron tube is mainly used as a transmitting tube. <IMAGE>

Filed: 1960-07-06
Abstract: A cyclohexylammonium salt of a phosphoric acid or boric acid is adsorbed on the surface of a pigment as wetting agent to facilitate the incorporation of a pigment into a binder.  The cyclohexyl ammonium salts conform to the general formula <FORM:0903611/III/1> where R1 = cyclohexyl radical R2 = cyclohexyl radical, hydrogen or alkyl radical with at least 6 carbon atoms. A = anion of meta-, pyro- or orthophosphoric acid or of boric acid.  Pigments specified are zinc white, lithopone, titanium white, cadmium red and cadmium yellow.  The salt is added preferably as an aqueous solution, to which ammonia may be advantageously added, to the aqueous paste of the pigment before drying.  Drying temperature must not exceed the decomposition temperature of the salt.  In the examples an aqueous solution of cyclohexyl-ammonium phosphate is formed.  This solution, to which ammonia has been added, is added to lithopone or zinc sulphide.

Title: Apparatus for positioning a workpiece

Filed: 1971-04-19
Abstract: 1323830 Telemotor systems INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [31 March 1970] 23744/71 Heading F1P An apparatus for positioning a workpiece comprises a transmitter 15 capable of coarse or fine adjustment to cause, via a liquid column 18, 50, 58, operation of a receiver 55 having an output shaft 62 connectable to the workpiece. The transmitter is actuated by rotating a ring 16 to cause axial displacement of a small secondary piston 20 alone or simultaneously with a large main piston 19. When both pistons 19, 20 move together a screw 28 on the ring 16 engages a tang 27 on a driver 26, which thus rotates with the ring 16. Rotation of the driver 26 rotates, through a sliding pin and slot connection 24A, 25A, a member 23 screwed into a bore 17B. The member 23 bears against a thrust bearing 31 to move the pistons 19, 20, which pistons are sealed by a rolling diaphragm 21. To move only the secondary piston 20, the ring 16 is moved through the range in which the screw 28 is dis-engaged from the tang 27. This rotates a shaft 38 screwed into a sleeve 41 fixed to the member 23, whereby a ball 37 and the piston 20 are moved without moving the piston 19. Stops 36 on a fixed key 33 are engaged by a pin 24C on the member 23 to limit its movement. A spring 68 in the receiver 55 acts to return liquid to the transmitter.

Abstract: A hydrocarbon oil, such as a crude oil, is converted by introducing it by a <PICT:0773121/III/1> line 2 into an upper part of a cooking vessel 1 containing fluidized solids, such as coke particles, at 650 DEG  to 850 DEG F., which vaporize light components, the liquid containing coke particles and vapours being conveyed by a line 4 to a cyclone separator 5, and from there particles with adhering unvaporized liquid are transferred by a line 13 to a lower portion of the vessel, separated from the upper part by a perforated plate 3, containing fluidized solids at 900 DEG  to 1050 DEG F., where the unvaporized liquid is converted to gasiform products and carbonaceous residue which is deposited on the solids, the conversion products passing upwards through plate 3 and fluidizing the solids in the upper part of the vessel.  A stripping gas, such as steam, is introduced by a line 14, and stripped solids are circulated by a line 15, after cooling in heat exchanger 16, to the upper part of the vessel, in an amount of 1 to 50 lbs. per lb. of feed oil. Stripped solids are also circulated by lines 17 and 19 to a transfer line burner, where the solids are heated to 100 DEG  to 300 DEG F. above the cooking temperature, and returned by lines 22 and 23 to the lower part of the vessel.  Vapours from cyclone 5 pass along a line 7 to a separator 8 where further liquid is separated and sent to the lower part of vessel 1 by a line 11. The oil may be topped, and may also be a shale oil, coal tar or synthetic oil.  Instead of coke, sand, clay, spent catalyst, metal shot, or glass or ceramic beads may be used.
