Title: Improvements in receptacles for the cuttings or punchings from perforating or punching machines
Inventor: TURNER FREDERICK JAMES LESLIE
IPC: G06K1/02
Filed: 1966-01-24
Abstract: 1,110,264. Confining waste products in industrial processes. CREED & CO. Ltd. 24 Jan., 1966, No. 3128/66. Heading F4X. Chads (i.e. cuttings or punchings) from a perforating machine such as a high speed tape punch are discharged from the machine through a pipe into a collecting box 1 in which is provided an enclosure member 2 having therein an aperture A through which the chads pass to enter the box. The enclosure member 2 is spaced from discharge duct 3 and has an external surface B sloping downwardly away from the aperture A, whereby after a conical pile 5 of chads has accumulated in the box up to the level of the aperture A, subsequent chad accumulation 6 flows down the sloping wall B. Hence a greater quantity of chads can accumulate in the box 1 without danger of blocking the outlet end of the chad discharge pipe 3. In a further form described (Fig. 2) the surface B is the upper surface of a sloping wall (8) which is integral with the collecting box; and the aperture by which the chads enter the box is formed in this wall. Overflowing chad passes down the wall to an outlet from the collecting box and on to the floor of the workroom, thus giving visual warning to the machine operator the box needs to be cleared.

Abstract: 524,519. Grinding and polishing. CHRYSLER CORPORATION. Jan 31, 1939, No. 3288. Convention date, July 29, 1938. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 17, 1940.] [Class 60] In a method of and apparatus for finefinishing the surface of a work-piece the workpiece is subjected to a fine abrasive action while it is at a temperature substantially below normal room temperature so that it may withstand scratching by the grit of the abrasive element. In one form the work such as a cylinder 15 is mounted between centres 13, 14, on a bed 11 which is reciprocated longitudinally from a motor 21 through a crank-disc 19 and link 20. The work is rotated from a motor 18 through gearing 17. The tool-head 27 is mounted on the end of a lever 32 pivoted at 33 and urged to engage the tool with the work by a spring 45. An adjustable counterbalance 34 acts in conjunction with the spring to adjust the pressure between tool and work. The tool motor 28 has a spindle carrying an eccentric pin which reciprocates a slide block 39 in a direction parallel to the work axis. The finishing tool-block is pivoted to the slide block on a transverse pin 43 and the block is reciprocated through a short stroke at high speed while the bed 11 is slowly reciprocated. The work may be precooled to a temperature between 50‹F. and 10‹F. in a container maintained at the required temperature by dry ice or other means then placed between the centres and kept cool during operation by coolant which is pumped from a container 57 by a pump 59, supplied to the work by a line 62 and collected for return to the tank in a trough 64. The tank is cooled by a coil 53 forming part of a refrigerating system operated by a compressor 50. In some cases the work may be sufficiently cooled by the coolant only. In a modification, Fig. 3, a refrigerating tank 68 is mounted on the carriage 11 and the work is partly immersed in the coolant which may be cooled by dry ice 49 or by a refrigerating coil. The coolant is withdrawn from the tank 68 and pumped over the work whence it returns to the tank. In another modification the entire finishing apparatus is disposed in an enclosure which is cooled by cold air circulation or by a refrigerating coil or both.

Patent GB-490215-A (GB)
Title: Improvements relating to the waterproofing treatment of textile fabrics and the like
IPC: D06M15/15
Filed: 1937-02-06
Abstract: Textile materials are rendered waterproof and fast to soap by impregnation with a solution containing an albumen or globulin or both which is subsequently coagulated by heat, the treatment being associated with a treatment with a higher fatty acid or soap or both. The albumen or globulin solution is preferably buffered to the iso-electric point.  Coagulation may be effected by high-pressure steam for a short period or by prolonged treatment at lower temperatures.  The soap preferably contains at least 50 per cent of the fatty matter in the form of saturated higher fatty acids and its solution is preferably reduced to a pH value of 7,0-7,5 by addition of acetic acid or unneutralized Turkey red oil.  The soap solution is applied at temperatures above 200 DEG  F.  Instead of soaping, an emulsion of a fatty acid may be added to the albumen solution.  Waxes may also be emulsified with the albumen solution.  The process may be applied to fabrics already waterproofed by wax emulsions such as are described in Specifications 380,052, 380,065, 380,076; 394,816, [Group IV], and 421,519, or by impregnating with proteins such as casein in neutral or alkaline media and causing combination of the protein and an amphoteric metal compound by rendering the system acid. Examples describe: (1) padding with a solution of dried egg albumen containing sodium chloride and thymol or salicylic acid, and buffered to pH 4,5 by sodium acetate and acetic acid, steaming at 120 DEG  C. and boiling with soap; (2) treating a cotton poplin with an emulsion made by mixing paraffin wax, liquid paraffin and the mixed fatty acids from beef tallow, incorporating the mixture at 50 DEG  C. in an emulsifying machine with an aqueous solution of egg albumen containing thymol, diluting with cold water and adding acetic acid to give a pH value of 4,5, followed by steaming; (3) treating viscose yarn with an emulsion containing albumen, paraffin wax and soap made from beef tallow and acidified with acetic acid, which converts the soap into free fatty acids, and steaming; (5) treating silk fabric with an emulsion of albumen, stearic acid and oleic acid similarly acidified, and steaming; (6) wetting out felt hat shapes with sodium acetate solution, hydroextracting and treating as in example 2. Concentrated emulsions suitable for use after dilution may be made by (1) dissolving egg albumen in cold water, adding dilute acetic acid, heating to 50 DEG  C., and emulsifying with a soap solution containing paraffin wax and thymol heated to the same temperature, to form an emulsion of albumen, wax and free fatty acid; (2) emulsifying at 50 DEG  C. a solution of egg albumen containing thymol with paraffin wax and liquid paraffin.
