Title: High molecular weight polymers of acetylenic hydrocarbons and process for preparing them
IPC: C08F10/00
Filed: 1956-03-12
Abstract: Polymers of molecular weight above 1,000, containing linear chains of units of the formula -CH=CR- where R is hydrogen, an alkyl or an aryl group, are made by polymerizing acetylene or a substituted acetylene of the formula CH­CR where R is an alkyl or an aryl group, in the presence of an inert organic solvent and a catalyst obtained by contacting a halide, oxyhalide, alkoxyhalide,, or alkoxide of a metal of Groups IVA, VA, VIA or VIII of the Periodic Table with an organo-metallic compound of a metal of Group 1A, or II, of the Table, or aluminium.  With gaseous acetylenic hydrocarbons the polymerization is generally effected under superatmospheric pressure and the hydrocarbon may be diluted with an inert gas such as nitrogen, hydrogen, or methane.  The polymers may be chlorinated or hydrogenated, e.g. at 100-200 DEG  C. in the presence of Raney nickel.  The polymers may be mixed with natural or synthetic rubbers prior to vulcanization. In Example (1), acetylene is polymerized in benzene in the presence of a catalyst consisting of titanium trichloride and triethylaluminium; in Example (2), acetylene is polymerized in n-heptane in the presence of triethylaluminium and titanium tetrachloride; in Example (3) acetylene is polymerized in n-heptane in the presence of anhydrous ferric chloride and triethylaluminium; in Example (4) acetylene is polymerized in n-heptane in the presence of vanadium trichloride and triethylaluminium; in Example (5) acetylene is polymerized in the presence of n-heptane and a mixture of triethylaluminium and a mixture of molybdenum trichloride and pentachloride; in Example (6) acetylene is polymerized in the presence of heptane and triethylaluminium admixed with titanium tetraisopropoxide; in Example (7) phenylacetylene is polymerized in the presence of benzene and titanium trichloride admixed with triethylaluminium; in Example (8) ethylacetylene is polymerized in heptane in the presence; in Example (9) phenylacetylene is polymerized in benzene, in the presence of titanium trichloride and diethylzinc; in Example (10) acetylene is polymerized in heptane in the presence of triethylaluminium and vanadyl isopropoxide; in Example (11) phenylacetylene in benzene is polymerized in the presence of triethylaluminium and titanium tetraisopropoxide; in Example (12) acetylene is polymerized in heptane in the presence of diethylaluminium chloride and titanium tetraisopropoxide; in Example (13) 1-hexyne is polymerized in heptane in the presence of titanium, trichloride and triethylaluminium; and in Example (14) acetylene is polymerized in heptane in the presence of trihexylaluminium and titanium tributoxide-mono-n-dodecoxide.

Title: Method of making an insulated splice or an insulated terminal
IPC: H01R9/05
Filed: 1974-02-20
Abstract: 1468369 Making electrical connections; heating dies; jointing GENERAL STAPLE CO Inc 20 Feb 1974 [23 Feb 1973] 7737/74 Headings B3A B3Q and B3E [Also in Divisions B5 and H2] In the production of insulated splices or terminals on electrical conductors by feeding a composite continuous strip comprising a layer of electrically non-conductive material adhered to one surface of a layer permanently deformable electrically conductive material, severing a predetermined length of the strip and crimping the severed length about the conductor or conductors so that the layer of permanently deformable electrically conductive material is fully disposed within the layer of electrically non- conductive material, crimping is effected by forcing the severed length into a die which may be heated by heating coils. The composite strip may be advanced to a position above a temporarily positioned anvil beneath bending bars 28, 29 and driving ram 30, and the bars 28, 29 moved downwardly to sever a predetermined length L of the strip from the remaining supply and to bend it to a U-shape. The anvil is then removed and driving ram 30 then descends between bars 28, 29 to drive the length L into crimping die 32 about wires 44 and 48 to be joined in depressions 36 and 38, the splice formed being heated above the softening temperature of the non-conductive material by heating coils 75 in the die so that the non-conductive material is fused and sealed to the conductors. Insulation of the splice may be improved by introducing molten plastics material through an aperture in the die cavity. The crimping die may comprise three segments, the central segment being of harder material than the outer segments and the heating coils 75 located only in the outer segments. In the production of an insulated terminal a T-shaped portion comprising an eyelet may be severed from the composite strip and crimped about the conductor.

Filed: 1923-03-17
Abstract: 195,616. Schneider et Cie. March 30, 1922, [Convention date]. Modifying scale of readings-A range-finder for aerial targets is combined with auxiliary apparatus by which automatic adjustment of the reading is effected in accordance with the variation of the sight-angle. This auxiliary apparatus consists of a Wheatstone bridge, one arm K<4> of which is constant, one K3H is varied by the handwheel B in accordance with the variation in altitude of the target, another value of in accordance with the variations in the value of the sine of the angle of sight, and the fourth s varied so as to balance the bridge. This final adjustment is made by the handle u<1> and transmitted directly to the scale of the rangefinder by gearing u<4>. The Wheatstone. bridge is contained within a casing C, acting as a support for the bearings L<1>, L<2> of the rangefinder, and is operated by an operator independent of the observer. In a modification mechanical means are utilized in place of the Wheatstone bridge, in which a couple equal to K<1> sina is balanced by a couple produced by a constant weight displaced through a distance proportional to the adjustment required and acting through an adjustable leverage proportional to the altitude of the target. The mathematical basis of the invention is described in the Specification, and Specifications 127,280 and 177,147, [both in Class 92 (ii), Ordnance &c.], are referred to.

Title: Process for the continuous distillation of tars
IPC: C10C1/04
Filed: 1950-03-28
Abstract: <PICT:0681737/III/1> In the continuous distillation of tar, especially coal tar, using a heater, flash-eyaporator and fractionating-column connected in series, a liquid side-stream is withdrawn from the column and recirculated, together with fresh tar, to the heater, flash-evaporator and column.  The process obviates the decomposition of components of high molecular weight, in tars having a high content of pitch.  Water-free tar is passed through conduit 1 into coil 3 wherein it is heated under pressure.  The heated tar is then introduced into evaporation-chamber 5 which is maintained at sub-atmospheric pressure.  The vapours, evolved in chamber 5, pass into tray-column 6, while the residue is withdrawn through line 7.  A fraction rich in naphthalene is withdrawn from the column through line 9.  A washing oil fraction containing a minor amount of naphthalene, is withdrawn from the column through line 13, and is returned to the tar feed-tank through conduit 14. The discharge from the base of the column, taken-off through line 10, is free from naphthalene; this discharge may be added to the residue withdrawn through line 7.  The process may be carried out using a series of flash-evaporation stages each of which is associated with a column.

Title: Improvements in or relating to sorting machines for perforated statistical record-cards
Filed: 1928-03-15
Abstract: 287,144. British Tabulating Machine Co., Ltd., (Assignees of Gray, A. E.). March 16, 1927, [Convention date]. Sorting cards.-In a machine for sorting perforated record cards means are provided for causing a sorting operation performed upon a card in accordance with a selected perforation to be repeated upon a subsequent card. For the purpose of checking wages, in a system wherein master cards with identification particulars accompany the wages cards and the wages cards themselves have perforations representing pay-roll numbers, the cards can be sorted according to the pay-roll numbers by the means described. The cards are fed to a sorting mechanism of the kind described in Specification 27067/07 and associated therewith is a device, for repeating the sorting operation, comprising an electromagnet 10, Fig. 1, an insulated latch 14 carried by the armature 11, and a cam-disc 15 frictionally mounted on a shaft 16a and normally held by the latch 14. The camdisc 15 as shown in Fig. 4, is carried by a sleeve 22 fixed to the shaft and is pressed into engagement therewith by a spring 23 held in position by a collar 21. An insulated contact 16 is adapted to co-operate with the raised part 17 of the cam-disc and a second contact 20 rides on the collar 21 the first contact being so arranged that the circuit is completed one card cycle after the raising of the latch 14. In the operation of the machine the stack of wages-cards and mastercards are fed from the magazine 24, Fig. 3 between the roller 26 and the brush 27 set to the pay-roll number column of the wages card. When the brush feels a perforation in this column the circuit through the holding electromagnet 28 is completed and the magnets 34, 35 are also energized. By the energization of the magnet 35 the circuit of the sorting electromagnet 30 is completed through the wires 41, 42, magnet 43, wires 44, 45, and contacts 37 whereby the armature 48 determines the compartment to which the card is to be delivered. At the same time the circuit through the electromagnet 10 is completed so as to raise the latch 14 and free the cam disc 15 which, one card cycle later, will close the circuit through the contacts 16, 20. and lines 59, 60 to the electromagnet 43 as above described to energize the sorting electromagnet 30 whereby the succeeding card (master card) is delivered to the same compartment. The contacts 37, 37<1> are opened during the passage of the cards to deenergize the electromagnets 28, 34 and 35. Starting controls. To start the machine a key 25 is provided in circuit with a stop key 61, electromagnets 62, 63, and a card contact 65. The key 25 is held down until the first card has been fed and the contacts 66 closed; thereafter the circuit is maintained until after the last card has been fed whereupon the contacts 66 are opened and the magnets de-energized.
