Title: Garment steaming or treating apparatus
IPC: D06F73/00
Filed: 1951-05-15
Abstract: 714,425. Drying garments. AMERICAN LAUNDRY MACHINERY CO. May 15, 1951, No. 11373/51. Class 34(1) [Also in Group VIII] Apparatus for steaming garments (see Group VIII) and drying them, comprises a hollow foraminous form 18 and means for causing the flow of a gaseous treating medium, such as steam or air, through a garment supported on the form, from the outside to the inside of the form through one part of the garment and simultaneously from the inside to the outside of the form through another part of the garment. The flow is preferably outward where the garment is thinner and inward where it is thicker, e:g. along the front edges and lapels. The form may be a flexible hollow cloth bag of torso shape when inflated, Fig. 1, or it may be rigid, being of woven wire or perforated sheet metal. In Fig. 1 the form 18 depends from a collar form 17 supported by upright bars 16. Air is supplied through a duct 13 by means of a fan 20 having an inlet 21, and is heated by means of heating coils 19. The inlet 21 is connected to a curved duct 28 communicating with two hollow holding members 29, 30, each comprising a sheet metal member provided with a foraminous front wall, e.g. of wire mesh screen. The members 29, 30 may be enclosed within or covered at the front by a pervious fabric member. The reduced pressure within the member 29 holds the front edges of the garment while the rear member 30 maintains the coat tails in proper alignment. A gravity biased pressure relief valve may be provided in the duct 21, Fig. 6 (not shown), to relieve the burden on the fan should the thickness of the garment offer too great a resistance. In a modification, Fig. 8, the holding members 29, 30 are located inside a rigid form 18a. An opening 40 in the duct 13 can be closed by means of a damper 41 actuated by a treadle 43. In the position shown in Fig. 8 the damper blocks the flow of air to the form 18a and directs it through opening 40 to atmosphere.

Title: Preparation of resin encapsulated particulate rubber
IPC: B01J2/28
Filed: 1973-03-09
Abstract: 1401367 Coated elastomeric particles GOODYEAR TIRE & RUBBER CO 9 March 1973 [7 April 1972] 11503/73 Heading B2E Elastomeric particulate material of the powder, crumb or pellet type is coated to obtain a dry, non-conglomerating product by mixing and coagulating a slurry of the particulate material, a coagulant and a resin latex, the latex having a concentration of 0.1-8% by weight of resin, the coagulant being 0.01-10% by weight aqueous solution and the coating being carried out at a temperature between 5‹C under the agglomeration temperture and the lower of the melting or decomposition temperatures of such resin. The elastomers may be styrene-butadiene, acrylonitrile-butadiene, polybutadiene or polyisoprene rubber. The particulate material may include oil, carbon black, silica, clay and may comprise primarily such materials bonded together with the elestomer. The coating resin may be styrene-butadiene copolymer, styrene-butadienedivinyl benzene terpolymer, acrylonitrile-styrene-butadiene terpolymer, polyvinyl chloride, polystyrene and polymethyl methacrylate. Examples of suitable coagulants are aluminium sulphate, magnesium sulphate, calcium chloride, calcium oxide and barium hydroxide. The resin latex may be added to the aqueous solution of the coagulant in which the particles are slurried. Alternatively the particles may be slurried in the latex, and the coagulant solution added slowly. In a typical example a slurry of elastomeric crumbs is prepared by slowly pouring styrene-butadiene rubber latex (23% solids) into an agitated solution containing 24 grams alum and 2000 grams water at 90‹C and heating the resultant slurry. Polyvinyl chloride latex at 70‹C was then allowed to flow slowly into the agitated slurry from a pressurised bomb, the temperature of the slurry being maintained always above 155‹C to produce a polyvinyl chloride coating on the surface of the slurried elastomer crumbs.

Title: Improvements in or relating to web winding apparatus
IPC: B65H19/22
Filed: 1954-04-22
Abstract: 761,807. Cutting webs. ROWLANDS, T., LUDDINGTON, E., and MOLINS MACHINE CO., Ltd. April 20, 1955 [April 22, 1954], No. 11667/54. Class 31 (1.). [Also in Group XVI] In a web-winding machine (see Group XVI) a web W, Fig. 3, is cut after a predetermined length has been wound into a roll R<SP>1</SP>, by a rotating knife 2 co-operating with a fixed knife (not shown). The knife 2 is rotated by a shaft 36 through one revolution each time a switch 43 is closed by a pivoted arm 20 when the roll R<SP>1</SP> reaches a predetermined diameter. Closure of the switch 43 supplies current to brushes 44 of an electromagnetic clutch having an armature 40 loose on a shaft 38 carrying a magnetic hub 39, such that a sprocket wheel 41, loose on the shaft 38 but secured to the armature 40, drives the shaft 38. The shaft 38 has a pini�n 37 meshing with a pinion 35 of twice its diameter on the shaft 36. Thus, cutting of the web is effected upon closure of the switch 43. The shaft 36 is stopped after one revolution by opening of a switch 45 in the armature circuit and closure of a switch 46 which supplies current to a magnetic brake 47 secured to a bracket 48. The switches 45 and 46 are operated by an arm 50 loose on a shaft 51 carrying a worm-wheel 52 driven by a worm 53. The arm 51 is rotated by the worm-wheel 52 by engagement of a detent 54 which is returned, by manual release of the detent, into engagement with a stop 55, after each operation of the knife 2. In a modification, wide flat plates 24 and 25, Fig. 2, are rotatable on shafts 26 and 27. The plate 24 carries a knife 28, while the plate 25 carries a co-operating knife or an anvil 29. The shafts 26 and 27 have meshing pinions 26a and 27a one pinion having one more tooth than the other, such that the knife 28 and anvil 29 will only co-operate to effect cutting once during a certain number of revolutions dependent upon the number of pinion teeth. Thus, by suitable selection of this number the web may be cut at predetermined lengths.

Abstract: 513,946. Making leading-in wires for electric lamps &c. EDISON SWAN ELECTRIC CO., Ltd., and HANNAFORD, A. April 22, 1938, No. 12108. [Classes 83 (ii) and 83 (iv)] Welding.-In making welded four-part 'composite leading-in wires for electric lamps &c. in a single automatic operation, the four wires are held longitudinally in a row with the outer pairs of leads in approximate contact and the inner pair overlapping, and welding heat is applied approximately simultaneously to the ,three points and the outer wires are moved longitudinally towards'each other so as to form two butt welds' and one lap weld. The composite wire may consist of a' nickel wire welded to a platinum wire, and a fuse wire welded to the platinum wire and also to a copper wire, the sections of wire being of different lengths. The wires a, c and b, d are fed from reels by two pairs of slides a<1>, c<1> and b'; d', to which they are clamped by electromagnets 8, the pairs of slides being reciprocated in opposite directions by levers 3 and cams 2 from the main shaft 1. The wires are fed through guides 11 and the wires a, b are received in electro-magnetically closed gripping jaws a<2>, b<2> and the wires c, d in electromagnetically closed jaws c<2>, d<2> which at this 'stage are in alignment with the slides c<1>, d<1>. Lengths are then cut off adjacent the guides 11 by knives 12 operated by a cam 19 on the main shaft. The pairs of jaws c<2>, d<2>, which are mounted on opposite sides of a pivoted arm 23 retracted by a cam 21, are now moved forward by a spring 22 so as to bring the wires carried thereby, which are overlapped, between the ends of the wires a, b. Welding blow-pipes 31, 32, 33 are then applied to the joints and the jaws a<2>, b<2> are moved endwise. Butt-welds at the outer joints and a tap weld at the inner joint are thus effected. The end pressure is provided by mounting the jaws a<2>, d<2> on leaf springs, which are retracted by electromagnets 37. The blow-pipes are normally held by springs 34 clear of the joints but are brought into action by electromagnets 35. The completed wire falls lengthwise down a shoot 38. Welding may alternatively be effected electrically as described in Specification 470,474. Specification 485,076 also is referred to.
