Title: Improvements in work holders or chucks for lathes and like machine tools
IPC: B23B31/163
Filed: 1919-11-14
Abstract: 160,216. Whitehead, J. Nov. 14, 1919. Chucks.-In concentric chucks for lathes and like machine tools, means are provided for rapidly bringing the jaws into contact with the work, and for securing a powerful grip by a second toggle operation. Fig. 1 shows the interior of a chuck or face-plate 3 in which the jaws have projections 2a engaging the slots b, and mounted on radial screws 4 carried in the radially sliding brackets 5. These brackets 5 are connected by the toggle system 6, 6a and 8 to brackets 9 radially movable by the screws 10. Rotation of the rack hand-wheel 11 causes the jaws to engage the work. The rack hand-wheel 13 is then turned, and the resulting rotation of the screws 10 causes the toggle system 6, 6<a> to straighten, thereby powerfully gripping the work. The application of such a toggle system to chucks in which the preliminary rapid adjustment is effected by a scroll is described, and a method of operating the toggle by a sleeve under axial screw control is also shown.

Title: Improvements in perforated tape transmitters for signal recorders
IPC: H04L21/02
Filed: 1933-10-13
Abstract: 427,321. Copying-telegraphy. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Oct. 13, 1933, No. 28382. Convention date, July 18. [Class 40 (iii)] A printing-telegraph system in which a combination of impulses is transmitted corresponding to the analysis of the character into constituent elemental areas and in which a different impulse combination is provided for each character, employs a tape perforated according to the five-unit code in conjunction with means for transmitting the appropriate impulse combination corresponding to a character which is normally transmitted by a code combination preceded by the case-shift signal. When the tape 16 has been stepped forward by the feed wheel 10, a cam c allows the feelers 7 to rise and the bars 9 selectively move to the right under the action of their springs. The selector lever 11 falling into aligned notches in the bars 9 and in a bar 12 moves an intermediate operating member 3 so that the contacts 4, 5 are actuated by the associated cam 2 on the constantly rotating shaft 1. A cam b on the shaft 1 removes the member 3 out of its operating position and the lever 11 from the aligned slots, whilst a cam a restores the selector bars 9 to their normal position. When a shift or reshift combination in the tape is engaged by the feelers 7 the bars 9 move so that aligned slots 9 are opposite one of the bars 11<a> which on actuation engages the associated inclined surface 13 or 14 of the bar 12 which is moved to its alternative position in which it is held by a notch engaged by a spring 15. When the bars 9 are positioned according to the succeeding combination of perforations, the bar 11 appropriate to the character falls in the aligned slots of the bars 9, 12 and brings the contact member 3 into association with the cam disc which transmits the impulses according to the character.

Title: A process for the pyrolysis of hydrocarbons
IPC: C07C2/00
Filed: 1931-10-14
Abstract: The thermal decomposition of gaseous aliphatic hydrocarbons or mixtures of or containing them is effected in a reaction space arranged in juxtaposition to a heating space through which hot gases are passed, a reduced pressure of substantially the same value being maintained in both the reaction space and the heating space; the pressure in the reaction space may be a little higher than that in the heating space.  Automatic means for regulating the pressure or for maintaining the required pressure difference may be provided.  A regenerative system, in which the heat of the reaction products and of the used heating gases is recovered, may be used.  The walls of the reaction space may be of refractory ceramic material, and known catalysts for the process may be present.  The process may be applied to the manufacture of acetylene from methane.

Abstract: 1,150,554. Coated flexible sheet materials. IMPERIAL CHEMICAL INDUSTRIES Ltd. 30 June, 1966 [7 July, 1965], No. 28787/65. Heading B2E. A coated, non-woven, fibrous sheet material comprises a flexible fibrous batt, a layer of film material having a modulus higher than that of the fibrous batt adhering to one surface of the batt by means of an adhesive layer of synthetic polymer and a coating layer of synthetic polymer covering the layer of film materials. The film may be of regenerated cellulose, polypropylene, polyester, polyamide, or polyurethane. The batt may be wholly or partly of synthetic fibres such as polyesters, polyolefines or polyamides. Part at least of the fibres may be shrinkable and the bat may be consilidated by a shrinkage treated. Polyethylene terephthalate fibres may be used for such a process. The batt may be needle-punched and contain 20% to less than 50% by weight of an in situ retracted fibres and may be shrunk to about 35% of its original length and impregnated with a resinous or elastomeric filling agent. The coating may be of flexible polymeric material such as a polyurethane. In the example the batt was impregnated with butadiene/acrylonitrile copolymer and a scrape-coat was applied thereto using a doctor-knife to adhere a film of Melinex (Registered Trade Mark) which is then applied. A coating of a polyurethane elastomer or of regenerated cellulose may then be applied. Coatings on the film layer -may be rendered porous by incorporating therein soluble salt particles which may be subsequently leached out.

Title: Production of allyl alcohol
IPC: C07C33/03
Filed: 1945-10-30
Abstract: A catalyst composed of lithium phosphate, used for the preparation of allyl alcohol from propylene oxide, is prepared by the addition of an aqueous solution of a soluble lithium salt, e.g. lithium chloride or nitrate, to an aqueous solution of a tertiary alkali metal phosphate, e.g. trisodium phosphate, and the precipitate, after washing, is dried and crushed, or may be extruded into rods, dried and crushed. The lithium phosphate may be precipitated on an inert supporting material.  After use, the catalyst may be regenerated a number of times by passing oxygen, air, oxygen and steam, or air and steam over it at a temperature of 250 DEG  to 350 DEG  C.ALSO:Allyl alcohol, substantially free from carbonyl compounds, is prepared by passing propylene oxide vapours, if desired, with inert diluents, e.g. water vapour or nitrogen, over a catalyst composed of lithium phosphate, e.g. trilithium phosphate, at an elevated temperature, e.g. at 200 DEG  to 300 DEG  C., although maximum efficiency is obtained in the range 240 DEG  to 255 DEG  C.  The reaction may be effected in a long narrow tube surrounded with a liquid suitable for the transfer of heat, e.g. tetrahydronaphthalene. Unreacted propylene oxide may be recirculated over the catalyst.
