Patent GB-1450892-A (GB)
Title: Production of fibrils
IPC: D21H13/10
Filed: 1972-09-26
Abstract: 1450892 Extruding polymer dispersions IMPERIAL CHEMICAL INDUSTRIES Ltd 17 Sept 1973 [26 Sept 1972] 44401/72 Heading B5B Fibrils of a thermoplastic polymer are produced by forming a dispersion of molten or heat softened particles of the polymer in a liquid which is a non-solvent therefor, preferably water, which dispersion is forced through one or more orifices, comprising either a pair of mutually opposed circular orifices or a narrow gap defined by two orifices fed by an orifice passing through the surface of one plate so that the polymer particles are deformed by the high shear forces to produce fibrils. A surfactant, preferably a partly soluble bifunctional polymeric material may be added to stabilize the dispersion. Part of the liquid may be removed from the fibrils by flash evaporation thereby cooling the remaining liquid to solidify the fibrils formed. Suitable apparatus may comprise a stirred pressure vessel 2 communicating with a small heated pressure vessel 12 containing two mutually opposed circular jets 14 into which the dispersion is forced from vessel 2, said jets being connected to expansion vessels 19 to separate vapour from the dispersed fibrils.

The delivery nozzle 15 of the parent Specification is prevented from being accidentally withdrawn from the socket 14 in the actuating button 10 by a sleeve 19, Fig. 1, encircling the button and engaging an abutment 18 on the nozzle, or, alternatively, by a sleeve 120b, Fig. 11, which is a snap fit on the container neck and also guides the button. Sleeve 120b has an abutment 126b which co-operates with a member 127 on nozzle 15 to prevent depression of the actuating button until the nozzle 15 is moved into its operative position, with the abutment 126b and member 127 out of register. As shown, abutment 126b is arcuate. In Fig. 4 (not shown), the abutment is straight, and is effective over a smaller range of movement of the nozzle.

Title: Improvements in or relating to the manufacture of sheets or strips of natural and/orsynthetic elastomer
IPC: B29D30/00
Filed: 1963-11-13
Abstract: 976,456. Laminates. PIRELLI S.p.A. Nov. 13, 1963 [Dec. 5, 1962], No. 44764/63. Heading B5N. A process for manufacturing strips or sheets of natural and/or synthetic elastomer, suitable for use in zones of a pneumatic tyre where considerable thickness is required, comprises (a) forming a unit by superimposing two layers of elastomer each layer containing a group of ingredients different from that contained in the other, the ingredients being such that in combination they are sufficient to initiate vulcanization under weak heat treatment, and each group being capable by itself of initiating vulcanization under stronger heat treatment; (b) subjecting the unit to a weak heating action; and (c) stopping the weak heating action when the inner part of the unit is cured but the outer surfaces are uncured. The cured inner part imparts good mechanical resistance to the unit as a whole, but the outer part in their uncured condition possess the necessary degree of tackiness to ensure satisfactory union with other elements of the tyre. In an example two strips are used comprising S.B.R rubber and compound ingingredients, the one containing mercapto-benzothiazole and the other diphenyl guanidine. The composite strip is subjected to weak heating action for ten minutes at 120 C. and is then incorporated in the tyre and subjected to stronger heat treatment e.g. for 40 minutes at 140 C. when the uncured outer portions become cured.

Title: Improvement in the production of acetylene and olefins by pyrolysis of hydrocarbons
IPC: C10G9/36
Filed: 1960-12-30
Abstract: Acetylene and ethylene are obtained by the pyrolysis of hydrocarbons, at a pressure higher than 3 atmospheres absolute, by contact with hot gases obtained by reaction of a combustion gas with oxygen both of which are saturated with water heated by the reaction products and then preheated before the combustion.  In the drawing oxygen from source 2 and combustible gas from source 1 (e.g. residual gas) are saturated <PICT:0969494/C4-C5/1> with water in columns 4 and 3, preheated and reacted in zone 6 of the reactor.  Part or all of the combustion gas may be replaced by gasoline, e.g. part of the pyrolysis feed from source 19 which is also saturated with water. Hydrocarbons to be pyrolysed are introduced at 7 and 9 and the products quenched with water at 11. The hot water obtained is used in column 4.  The gases are further cooled indirectly in heat exchanger 13 with water then used in column 3.

Abstract: 1,157,705. Pyrolytic carbon structure. GULF GENERAL ATOMIC Inc. 17 Oct., 1966 [22 Oct., 1965; 15 Feb., 1966], No. 46312/66. Heading C1A. [Also in Division C7] Particulate materials are coated with a coating which includes a dense, isotropic layer of pyrolitic carbon. The material to be coated is placed in a tube, such that the ratio of the particle surface area in square cms. to the remaining volume in the tube in cubic centimetres is at least 5 to 1, and is heated to the operating temperature which is generally over 1,600 C. The material is fluidized by passage of an inert gas such as helium or nitrogen, the inert gas containing a hydrocarbon e.g. methane which decomposes to give a layer of carbon on the particles. A spongy layer, between the particle and the hard carbon layer having a density of 1-5 gm/cc. or less may be produced by using acetylene in the same process. The rate of gas flow is arranged so that the contact time of any atom of gas with the particles is less than 0À3 second. The coated particles and the carbon layer are claimed per se, the carbon layer being further characterized by having a density of at least 1.8 gm/cc an apparent crystallite size of at least 100  and a Bacon Anisotropy Factor between 1À0 and 1À3.

Driving control; manual locking arrangement; covers.-In an electric typewriter of the type having a displaceable cover 7, which when moved from the masking position, operates a manual control 27 to switch off the electric motor (33, Fig. 1) and lock the keyboard, provision is made to allow the control 27 to be switched on with the cover 7 in the displaced position. The manual control 27 is pivoted at 28 and carries a cam 26. A rearwardly extending arm 29 of the control 27 has a pin-and-slot connection with a lever 30 which controls a switch (32, Fig. 1) in the circuit of the electric motor (33). The cam 26 of the control 27 co-operates with a follower on a spring biased, pivoted lever 34, co-operating with a two-armed lever (39) pivoted at (41, Fig. 4), which in turn co-operates with an arm (42) of a bail structure pivoted at (40), which includes a universal locking bar (43) for locking the keyboard. The displaceable cover 7 is pivotally mounted at 10 and 14 to arms 8 and 11, themselves pivotally mounted at 9 and 13 respectively to the machine. Associated with arm 11 is a cam 16. Mounted for axial movement on a shaft 20 by two spaced ears 19, is a plate 18 which carries an arm 25 and a cam follower 17 for the cam 16. Springs 22 and (23, Fig. 3) bias the plate respectively downwards on to a stop 21 and rightwardly (as viewed in Fig. 3) against the inner frame 4 of the machine. Movement of the cover 7 from the masked position, causes cam 16 to pivot the plate 18 to the broken line position, so that the arm 25 co-operates with the cam 26 to move the manual control 27 to the " off" position, if not already there, and thereafter retain it there. Should it be necessary to switch the manual control " on " with the cover 7 in the displaced position, the plate 18 is moved leftwardly along the shaft 20 against the bias of spring 23, thereby disengaging the arm 25 and the plate 18 from the cams 26 and 16 respectively, whereupon the plate 18 moves down against the stop 21 to latch behind the cam 16. It is then possible to move the manual control 27 to the " on " position, without the cam 26 coming into contact with the arm 25. Restoring the cover 7 to the masked position, rotates the cam 16 to the position shown in Fig. 2, which allows the plate 18 to be moved by spring (23) rightwardly to its original position.
