Title: Improvements in the slicing of extruded plastic materials
IPC: A23G3/02
Filed: 1944-07-26
Abstract: 595,252. Cutting extruded material. SEARLE, G. H., and WEBB, W. D. L. July 26, 1944, No. 14308. [Class 87 (ii)] Plastic material is cut into pieces as it emerges from an extrusion nozzle 14 by a series of cutting wires 28, carried by two endless chains 21 lying in planes parallel to the direction of extrusion. Sprockets 20 which drive the chains are carried by the extrusion head 15. The cutting wires slide across the face 141 of the extrusion nozzle at an angle to the vertical so chosen in relation to the speed of extrusion that the cut face is, e.g., at right angles to the other four faces. At the end of the cutting stroke the wire tilts the cut piece forwardly so that it falls, with the newly cut face on top, on to a conveyer 29. The return path of the chains 21 may lie in front of the extrusion nozzle 14. The extrusion head is mounted on bars 17, 22 and may be reciprocated in a direction transverse to the direction of extrusion as described in Specification 595,253. The plastic material is fed to the extrusion head through a flexible tube 12. Specification 363,137, [Group X], also is referred to.

Title: Manufacture of ammonium bicarbonate
Inventor: BROOKS RICHARD
IPC: C01C1/26
Filed: 1952-06-09
Abstract: Ammonium bicarbonate is produced by absorbing equimolecular quantities of ammonia and carbon dioxide in an aqueous solution containing carbon dioxide and ammonia in the ratio of 1 : 1 to 3 : 4 by weight and nearly saturated therewith, said absorption being carried out at a temperature of 30-35 DEG C. at atmospheric pressure in a packed tower, allowing the temperature to rise to 45-50 DEG C., cooling the resulting solution to 25-30 DEG C. to produce a supersaturated solution, and crystallizing ammonium bicarbonate therefrom, e.g. in the presence of seed crystals.  The mother liquor resulting after separation of the crystallized ammonium bicarbonate is returned to the absorption process, after the addition of make-up water if necessary.  An absorption of equimolecular amounts of ammonia and carbon dioxide is effected by adjusting the proportions of these gases fed to the tower.  An excess of up to 20 per cent carbon dioxide may be employed.  Prior to the main absorption step, the solution may be treated with gaseous or aqueous ammonia, and then cooled.  Lime kiln gas may be used as a source of carbon dioxide. The waste gas from the absorption tower may be washed with water, and the resulting solution used as make-up water.

IPC: B21C23/22
Filed: 1955-05-20
Abstract: 812,819. Extruding; forging. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 15, 1956 [May 20, 1955], No. 14688/55. Class 83 (4). A method of forming articles from titanium by pressure flow-working, in which the titanium is provided with a ductile metallic coating which acts as a lubricant during the working. The coating may be of aluminium, aluminium alloyed with niobium, silver, or silver alloyed with manganese, tin, cadmium or zinc. The coating is applied by electrodeposition, metal spraying, or dipping in a bath of molten coating metal especially when aluminium is used as the coating. In this case the titanium is first cleaned in a fused caustic bath to remove oxide scales and after neutralizing the caustic, the titanium is plunged into a bath of aluminium at 650‹ C. The coated titanium may be worked immediately at this temperature or the temperature may be further raised, for example, by lowfrequency induction heating. Alternatively the coated titanium may be allowed to cool and be subsequently re-heated and worked. The working operation may comprise extrusion at a temperature of 800‹ C., impact extrusion or warm extrusion. A sheet of glass cloth may be wrapped around the coated titanium billet before extrusion and in this case the extruded product may be subsequently de-scaled by treatment in a sodium hydride or fused caustic bath. Alternatively the working operation may comprise die forging using only a thin coating of ductile metal on the titanium. Specification 684,013 is referred to. Reference has been directed by the Comptroller to Specification 749,365.

Title: Improvements in and relating to devices for transferring digital data from a medium to a recording device
IPC: H03M9/00
Filed: 1962-04-18
Abstract: 930,531. Statistical apparatus. EASTMAN KODAK CO. April 18, 1962 [April 19, 1961], No. 14994/62. Class 106 (1). A character is coded in each column of a perforated tape, Fig. 7, and is accompanied by a sprocket hole 11 and a parity bit 12, each group of seven characters being followed by an end of word tab. The six character bits set the appropriate bi-stable circuits 21, and their outputs are examined to determine whether the character read is a control symbol. The sprocket hole 11 causes three pulses to be produced in succession by unit 91, the first shifts the data already stored in one-word register 60 by one position, the second opens character gates 26 to enter the character in register 60, and the third pulse resets bi-stable circuits 21 reedy for the next character. In this way a sevencharacter word is entered in register 60. When the end-of-word tab is read, code filters (gates) 23, 25 inhibit gates 26 and prevent the register shift pulse being generated. The second pulse derived from the sprocket hole of the end-ofword tab, together with the associated parity bit releases the word stored in the register 60 in parallel to solenoid drivers 70 operating a code display device which is then photographically exposed. When an end-of-code symbol EC or an end-of-tape symbol ST are read immediately after en end-of-word tab , i.e. after the contents of the register nave been read out, filters 25 produce signals to stop the reader and advise the operator that the end of code has been reached. If the end-of-word tab is followed by the AC symbol, the reader is stopped and switch 97 is actuated so that data may be read from another tape. If desired, data may thus be inserted from the second tape, an AC symbol in this tape causing the input to be switched back to the first tape at the appropriate time. The switching from one tape to the other may occur at the end of, or in the middle of a word. One further control feature is described, and in this a numeric tag is used as the first character of the word when the remaining six characters are numerals. At the end of the word the tag is decoded from register 60 by gates 93, and the contents of the register are then supplied through gates to a relay decoding circuit controlling a " nixie " tube indicator.
