Title: Apparatus and Method for Drawing and Crimping Yarn
Inventor: SATTERWHITE FRED B
IPC: D02G1/12
Filed: 1967-10-17
Abstract: 1,198,850. Crimping yarn. KLINGER MFG. CO. Ltd. 17 Oct., 1967 [19 Oct., 1966], No. 47215/67. Heading D1F. In a process for drawing and stuffer box crimping, for example nylon, polyester, or polypropylene yarn, the yarn is deviated from a straight path between the downstream most draw roll and the feed rolls of the stuffer box so as to engage one of the feed rolls tangentially prior to the nip of the feed rolls. The yarn may be deviated by passage over a roll or pin which may be grooved, and which may apply moisture to the yarn. The yarn may pass through an aperture in a guide plate disposed between the roll or pin and the feed rolls. The stuffer box may be of the type having a toothed wheel to feed the crimped yarn through an arcuate setting chamber.

Filed: 1974-11-01
Abstract: Aliphatic amines of medium chain length are obtained by reacting epsilon -caprolactam with an amine of the formula RNH2, in which R denotes a straight-chain or branched, saturated or unsaturated aliphatic hydrocarbon radical having 10 to 14 C atoms and, if appropriate, by further reaction of the resulting compounds with a methylating agent or with ethylene oxide or propylene oxide or glycidol. These compounds and their acid addition salts with toxicologically acceptable acids have a bactericidal, fungicidal and algicidal activity.

Title: Tea extraction process
IPC: A23F5/28
Filed: 1965-11-12
Abstract: Dry tea is extracted with water at a temperature not above 110 DEG C. to provide a first extract, comminuting a quantity of the at least partially extracted tea and adding water thereto to form a pumpable slurry, heating the slurry to above 180 DEG C. to form a second extract, and combining the extracts.  The combined extracts may be dried, for example by spray drying.  Prior to mixing, the insoluble matter may be removed from the second extract, which is then rapidly cooled and concentrated.  Before or after concentration aromas may be stripped from the second extract and discarded.  Similarly, the first extract may be concentrated and subjected to aroma stripping, the stripped aromas being added to the combined extracts.  Prior to extraction, steam may be passed through the dry tea to yield an aromatic distillate which is combined with the combined extracts. The extracts may be solubilized in known manner, for example by treating with a sulphite, or by cooling to precipitate tannins, which are then oxidized and returned to the extracts.

Title: Pneumatically actuated driving machine for fastening members such  as nails and staples
IPC: B25C1/04
Filed: 1974-11-12
Abstract: 1454826 Stapler U MONACELLI 12 Nov 1974 [12 Nov 1973] 48811/74 Heading B4C A pneumatically operated stapler comprises a handle 1 forming a reservoir 8 for air a cylinder 10 a valve 21 movable in a valve guide 22 and able to close the top of cylinder 10, a piston 17 slidable in cylinder 10 having a hammer 18 to drive the staples and a trigger 47 which causes actuation of piston 17 when a safety device 63 is engaged by the workpiece. In operation when the stapler is connected to a supply of compressed air the valve 27 is held against the upper edge of cylinder 10 by pressure in annular space 28 which is connected to the reservoir 8. Upward movement of safety device 63 allows that when trigger 47 is raised air pressure which raises valve 46 is released to atmosphere and valve 46 drops cutting off pressure supply to space 28 and venting it to the atmosphere via ports 33. The valve 21 is raised by excess pressure below it and the pressure in reservoir 8 is applied to piston 17 through the gap between valve 27 and top of cylinder 10 thus causing the driving of a staple. During downward movement of the piston air below the piston is forced into compartment 19. Upon release of trigger 47 valve 46 returns to its original position and valve 27 is lowered. As the piston rises under air pressure from the reservoirs 19, a poppet valve 35 in the valve 27 rises to allow air above the piston to vent through parts 33 to atmosphere.

A cabinet front wall 2 is secured to a slidable, pull-out bottom 4 of the cabinet by a device comprising a plate 1 screwed to the rear face of the wall 2 and an angle member 5 screwed through its horizontal limb to the upper surface of the bottom 4 and having a vertical limb 6 which carries the plate 1 for vertical adjustment. A channel rail 7 is secured to the vertical limb 6 and houses a square section tube 11 secured to the plate 1. A spindle 10 is supported in end bearings 8, 9 of the rail 7 and is threadedly engaged in nuts 12 in the ends of the tube 11 so that rotation of the spindle 10 using a screwdriver slot 13 effects vertical displacement of the tube 11 and hence the plate 1 and wall 2. Horizontal screws slots 3 in the plate 1 facilitate horizontal adjustment of the wall 2 position. The rail 7 may be welded to the limb 6. Alternatively, the rail 7 may be secured to the limb 6 by a lower pivot pin 17 and an upper, locking screw 21 engaged in a slot 20 in the limb 6 so that the inclination of the wall 2 may be adjusted.

Abstract: 1,064,737. Metal melting furnaces. SUNBEAM ENGINEERING CORPORATION. Dec. 16, 1963 [Dec. 21, 1962; Dec. 4, 1963], No. 49628/63. Heading F4B. Steel is produced in an uncompartmented furnace having two hearths, the gases produced by blowing the melt in one hearth with oxygen being passed over the other hearth to preheat a charge of scrap. The hearths 18, 20, which may replace the single hearth of an existing furnace, contain a melt at least four feet deep, and have separate covers (58, 60, Fig. 3, not shown) forming a two-part furnace roof. Each cover carries a retractable lance for the supply of oxygen and/or fuel for refining a charge, and tilted lances through which air or oxygen is supplied to burn the waste gases from the refining hearth and direct them on to the scrap charge for preheating. The end passages 42, 44 of the furnace are connected to the stack through a damper so that the flue remote from the refining hearth is operative and the gases flow over the preheating hearth. Each cover has two doors closing the charging opening 70 for scrap, and a trough 84 delivering molten metal tangentially to the hearth, Fig. 2. Each tap hearth has a central tap-hole 88 and a shoot 90. A number of cover members may be provided so that they can be repaired without interrupting production. A charging apparatus 13 running on rails 14, Fig. 1, comprises two scrap boxes 140, 138 and a retractable shoot 136 which enters the charging hole to each hearth. The height of the assembly may be adjusted by hydraulic rams (144, Fig. 7, not shown) and the scrap-boxes 140, 138 are tilted about their front ends by rams. A gate 154 in the shoot 136 directs the scrap from either box into the furnace. In a modification, a number of scrap bins are mounted on a turntable above the retractable shoot. Each bin is moved in turn above the shoot, and its bottom opened to charge the hearth.

Abstract: 1388696 Flame proofing fabrics HOOKER CHEMICALS & PLASTICS CORP 30 Oct 1972 [4 Nov 1971] 49981/72 Heading DIP Cellulosic material is rendered flame retardant by impregnating with an aqueous solution of a tetrakis (hydroxymethyl) phosphonium salt, at least partially drying the material by heating without fixing the phosphonium salt thereon, cooling the material or allowing it to cool and treating the material with gaseous ammonia to insolubilise the phosphonium salt by polymerisation. The cellulosic material may be cotton cloth, regenerated cellulose, cotton/regenerated cellulose and cotton/polyester fibre blends, wood and paper. The flame retardant may be tetrakis (hydroxymethyl) phosphonium chloride, bromide, acetate, sulphate or phosphate. Preferably its acidic nature is "partly neutralised" with 70 to 90% of the stoichiometric amount of sodium or potassium hydroxide, soda ash, triethanolamine or triethylamine to a pH of 5 to 6.5. Cotton cloth is padded with a 20 to 40% aqueous solution of the phosphonium salt. The padded cloth, containing 25% to 150% by weight of the solution is dried for 1 to 10 minutes in a 200F air oven or by hot pressing or by passage over heated drums. Drying may be complete or only to a 5 to 25% moisture retention. The cloth is then cooled by standing at room temperature for 1 minute to 16 hours, by spraying with water or by passage through a cold box or over cold drums. For comparison purposes the cooling may be omitted. The cloth is then treated with gaseous ammonia, a gaseous ammonia/steam mixture or with steam and then with gaseous ammonia. The phosphonium salt is polymerised and made fast to bleaching with aqueous hydrogen peroxide or alkaline sodium perborate and to home washing.
