IPC: G10K11/28
Abstract: 132,821. Mother, T., Irwin, J. T., Fletcher, G. H., and Webb, C. E. Sept. 25, 1918. Sound - directing appliances.-A soundreflector for submarine use is formed with a reflecting-surface of flexible or yielding material supported upon a rigid back member so as to yield freely to the vibratory movements of the liquid. In the construction shown in section in Fig. 2, the reflecting-diaphragm A is supported by ribs C formed on a carrier B built up from segments connected together by flanges b. The ribs C are shown as concentric rings, and the diaphragm may consist of a sheet of india-rubber clamped at its periphery. Air or gas is supplied to the space behind the diaphragm through a valve E, and the ribs or rings are perforated to allow the gas to pass. The reflector is preferably of spherical or paraboloidal shape, which is determined by the outer edges of the ribs, the diaphragm being supported between the ribs by the air cushion. When a vacuum is employed instead of an air cushion, the diaphragm is preferably made of thin sheet metal hammered or worked to the required shape. Differences of water pressure at the different parts of a large reflector may be compensated for by using different gas pressures for the different portions. The hydrophone or other sound-detector D is supported at the focal point by the legs d.

Title: Apparatus and a method of modifying coded information for operating a typesetting machine
IPC: B41B25/00
Filed: 1974-03-27
Abstract: 1462983 Cathode-ray tube displays HARRIS CORP 27 March 1974 [13 April 1973] 13606/74 Heading H4T The invention is concerned with a cathoderay tube (CRT) display system having control means which enables an operator to edit textual matter (e.g. advertising copy) so as to produce a desired final layout prior to typesetting. As shown in Fig. 1, each of a plurality of terminals, such as 1-22 can access a Terminal Control Unit (TCU) which includes a computer 1-10. At the terminal units a tape reader (or a keyboard) provides text data and layout instructions which are temporarily stored in a refresh memory and displayed on the CRT by bright-up of a line raster. The display is produced as shown in Fig. 2 with the text data on the right-hand side and the layout instructions, (such as 2-6), on the left-hand side. When access to the TCU is obtained the computer processes the text data in accordance with the instructions. The latter comprise e.g. for instruction 2-6 (Fig. 2), a quadding code "QR"= Quad Right, a line measure code "33", a fount code "VBC", a point size code "30" and a film advance code "11", the remainder of the instruction. being an indent code. Any of these parameters may be changed by operation of control and edit keys (see Fig. 3) and the text itself may be changed by means of the normal keyboard. When a parameter is changed by means of the edit keys the display code changes to indicate the new parameter value. However such parameter change may be effected by "overstriking" the parameter code with the new value by means of the normal keyboard which then causes the display automatically to change to the new value. When the operator is satisfied with the display the whole of the matter, text and layout instructions, is converted to a typesetting code, compatible with the typesetting equipment to be driven, by punching it out in line block format on an eight level paper tape. Subsequent changes may then be made by redisplaying the matter punched on the tape and inserting the required instruction changes. Details of the control logic 1-12 and refresh memory 1-13 in the TCU and of a terminal unit such as 1-20 are given with respect to Figs. 4 and 5 respectively (neither shown).

Title: Improvements in or relating to the polymerization of ethylenically unsaturated compounds
IPC: B01J23/02
Filed: 1957-04-29
Abstract: Catalysts suitable for olefin polymerization reactions (see Group IV (a)) are prepared by depositing an oxide of titanium, zirconium, thorium or hafnium on alumina, in the absence of any compound of a metal of Groups Va, VIa, VIIa or VIII and then treating the deposited oxide with the vapour of lithium, potassium, sodium, rubidium, caesium, magnesium, calcium, strontium or barium.  The oxide is preferably deposited on the alumina by impregnating the alumina with a solution of the corresponding alkoxide in an organic solvent and then converting the alkoxide to the oxide, e.g. by hydrolysis. Instead of the alkoxide any salt which may be converted to the oxide by hydrolysis or pyrolysis may be used, e.g. the chloride, nitrate, sulphate, acetate or propionate.  The product may be placed in a furnace wherein it is in contact with the vapour of one of the above-mentioned Groups I and II metals under vacuum for 1 to 20 hours.  The Group I or II metal is used in amounts of at least 1%, preferably 5 to 1000% by weight based on the oxide.  The alumina may be a commercial product or it may be prepared by dehydrating hydrous alumina, by gel precipitation from salt solutions or from metallc aluminium.  Examples comprise the following combinations on alumina: Ti/Na; Th/Na; Zr/Na; Ti/Li; Ti/Mg; Ti/Ca; in each case the Group Ia or IIa metal treatment was effected at a pressure of 0.5 mm. or lower.  Specifications 734,501 and 748,634 are referred to.ALSO:Olefins, such as ethylene, propylene and styrene, are polymerized in the presence of a catalyst (see Group III) obtained by depositing one or more Group IVa metal oxides on alumina in the absence of any Group Va, VIa, VIIa or VIII metal compound and contacting the product with vaporized Li, Na, K, Rb, Cs, Mg, Ca, Sr or Ba.  The catalysts may also be used for preparing copolymers of ethylene or other mono-olefines with copolymerizable olefins, e.g. propylene, butylenes, butadiene, isoprene, heptene and styrene.  The polymerization may be effected batchwise or continuously in the presence of a liquid diluent, e.g. cyclopentane, xylene, or toluene; or in the gaseous phase using a fixed, fluidized, co-current or counter-current bed technique. Condition may be up to 1000 atmospheres and up to 250 DEG  C., preferably 10 to 200 atmospheres and 100 DEG  to 225 DEG  C. Specifications 734,501 and 748,634 are referred to.

Title: Method and apparatus for elongating metal bodies
IPC: B21C1/22
Filed: 1960-04-19
Abstract: 912,645. Stretching; rolling. GENERAL ELECTRIC CO. April 19, 1960 [May 6, 1959], No. 13669/60. Class 83 (4). A method of increasing the length of an elongated body, such as sheet, strip, wire, rod or tube, and reducing its thickness is characterized by subjecting successive portions of the length of the body to cyclic plastic strain, simultaneously subjecting the same successive portions of the body to tension stress insufficient of itself to produce plastic elongation of said body, and simultaneously also subjecting the same successive portions of said body to pressure sufficient only in combination with the cyclic plastic strain and the tension stress to reduce the thickness of the body. Strip S from a reel 10 passes through two sets of processing rolls 13, 14, 15 to a reel 12, tension being applied to the strip by differential torque or angular velocity of the reels 10, 12. The cyclic plastic strain is produced by the changing of direction as it passes round the rolls 13 and the pressure is applied by the contact rolls 14, 15 against the rolls 13. The bending rolls 13 may be floating and the rolls 14, 15 fixed in position or, as shown in Fig. 3, the bending rolls 13 fixed in position and the rolls 14, 15 carried by frames 17 pivoted to a lever 19 rocked about a pivot 20 by a weighted lever 26 to adjust the pressure of the rolls 14, 15. The strip may be passed first through the machine from the reel 10 to the reel 12 then back from the reel 12 to the reel 10. In another embodiment, Fig. 7, reels 10, 12 (not shown), apply the tension and laminated plates 31, 32 vertically moved by oscillating plungers apply the pressure and, as a result of the transverse displacement, the cyclic plastic strain. In a further embodiment, Fig. 9a, the tension is again applied by reels 10, 12 (not shown), the pressure by rolls 42, 43 and the cyclic plastic strain by heating the strip between the rolls in a furnace 40. In another embodiment, Fig. 10, the cyclic plastic strain is applied by twisting and untwisting the strip as it is pulled through a die or twisting mill, pressure being applied by rolls. In a further embodiment, Fig. 11, the cyclic plastic strain is produced by heating by the passage of an electric current, rolls 59, 60 applying the pressure.
