Title: Improvements in wind-up attachments for fabric cutting machines
IPC: B65H18/20
Filed: 1923-07-20
Abstract: 221,612. Carpmael, A., (Ajax Rubber Co., Inc.). July 20, 1923. Set-off, preventing. - A wind-up attachment for a fabric-cutting machine is particularly intended to receive cut bias strips of rubber impregnated fabric and wind them up on a roll with the intermediation of a liner of muslin or other suitable material. The apparatus comprises a fixed table 114 and a surface 59 arranged to be moved into and out of operative relation with the table and supporting liner material which passes from a roll 57 to a roll 60. The strips are laid on the table 114 and one end pressed on the moving liner material. As the strips are drawn off the table wrinkles are automatically removed. The roll 60 rests on rollers 72, 73 driven, when the surface 59 is in operative position, by an electric motor 15 and a belt 17. So that the fabric-cutting machine may be allowed to work continuously, two sets of winding-up apparatus are provided. The other set comprises a supporting surface 86, a liner feed roll 85, and a receiving roll 87. Each set is mounted on a carriage on wheels on transverse rails, so that the set carrying a full roll 87 can be pushed sideways out of operative relation with the table 114 and the other set substituted. A flap 115 hinged to the table 114 rests on the surface 59 when this is in use, and falls into alignment with the surface 86 when this surface is operative. The surface 59 carries an inclined lifter 118 to raise the flap as the surface 59 is pushed into operative position. Clutches are provided on the pulleys driven by the belt 15 so that the rollers supporting the receiving rolls are driven only when their corresponding surface is in operative position. The belt is provided with a jockey pulley 25 controlled by an arm 28 adjacent to the feet of one of the operators. The rails have depressions to receive the wheels of the carriages in their extreme positions. The spindles of the receiving rolls are guided by angleirons 63.

Filed: 1948-07-15
Abstract: 652,005. Filaments united by adhesives. COURTAULDS, Ltd., FORD, C., and FOTHERGILL, F. July 15, 1948, No. 19019. [Class 120(iii)] [Also in Group VIII] A composite ribbon is formed by forming into a flat tape without twisting, a bundle of parallel, untwisted continuous filaments of synthetic high polymeric material and bonding together the filaments in the tape throughout their length whilst maintaining their parallel, untwisted condition, by treating the tape with a bonding agent in liquid form and consolidating the thus treated tape into the desired ribbon by solidifying the bonding agent. The filaments may be viscose or cuprammonium cellulose, cellulose acetate, or vinyl chloride-vinyl acetate copolymer and the bonding agent may be cellulose acetate or cellulose - acetate - butyrate; a cellulose ether; polyvinyl acetate; polyvinyl vinyl acetal; polyvinyl butyral; polyvinyl alcohol; proteins, e.g. gelatin or casein; gums or shellac. Mixtures of bonding agent, e.g. dimethyl phthalate or tricresyl may contain a plasticizer or softening agent. e.g. dimethyl phthalate or trocresyl phthalate. The bonding agent may be in solution in a low boiling solvent, e.g. acetone, methylene chloride or in water, or may be applied in the form of a hot melt, or as a powder which is subsequently heated, for example, by heated rollers. Either the filaments or the bonding agent or both may be coloured and other effects may be produced by incorporating mother of pearl or aluminium powder in either the filaments or bonding agent. The bonding operation may be effected by passing the tape through the nip of a pair of rollers, the tape having been treated with the liquid prior to reaching the rollers, or the liquid may be applied in the nip by partly immersing the lower roller in a bath of the liquid. In a further apparatus, the tape 1 is passed through a metal tube 3 containing a bonding agent, entering the tube through a hole 5 in a rubber bung 6, passing over tension bars 7 and 8 to form a flat tape, over a horizontal guide bar 11 and leaving the tube through a slot 12 comprising a die. The tape 'is then dried by infra-red heating and passes through calender rolls prior to being wound as a cheese Specification 539,797, [Group VIII], is referred to.

Title: Improvements in or relating to a process for the treatment of organic matter by fermentation
IPC: C05D3/02
Filed: 1937-07-10
Abstract: 500,548. Manures. PROCTOR, D. M. July 10, 1937, No. 19196. [Class 111] A fermented manure is obtained by mechanically pulverizing town and house refuse, moistening the pulverized mass with about 5-20 per cent of water, adding chalk or any other neutralizing agent to neutralize any acidity which is present or may develop, and storing the mixture in a stationary cell under aerobic conditions. The aerobic condition may be attained by forcing or drawing air through the mass, or by transferring the mass from cell to cell by means of a grab &c. which picks up the material from the top of one cell and drops it from a height to the bottom of another. This operation may be carried out three or more times at intervals of about three days. The refuse may be screened preferably during delivery to the pulverizer, which is preferably of the swinging hammer or ball mill type. Ammoniacal gas liquor or sewage sludge may be used for moistening the mass. Ferrous metal articles may be separated from the pulverized mass by means of a magnetic pulley. The fermentation cells may be made of reinforced concrete, brick or stone and may be constructed wholly or partially above or below ground level. Air may be admitted intermittently or continuously through pipes terminating in vents situated in the floor or the side walls and/or by pipes pierced with holes traversing the cell and/or terminated by nozzles projecting into the cell. The air should be uniformly distributed and the pipes should be so constructed that the air current is downwardly directed at the air exits from the vent holes or nozzles. The temperature may be regulated by the admission of air so that all points attain a temperature of 180-185‹ F. The removal of moisture may be assisted by the provision of pipes of ample cross-section leading from the top of the cell to an exhaust fan. The withdrawn gases may be deodorized by passage through a furnace. The final product may be subjected to drying or crushing and screening. Specification 487,837 is referred to.
