Title: Method of printing
IPC: B41M3/14
Filed: 1969-09-29
Abstract: 1286084 Printing processes; invisible inks MEREDITH CORP 29 Sept 1969 [27 Sept 1968] 47834/69 Heading B6C In a method of printing, a conventional visible ink is printed on a moving web 10 by an offset unit 12, 18, 20 and whilst the ink is still wet a low viscosity invisible ink is printed over the visible ink such that the latter wet traps over the forme 5.

Title: Sealing grid for forming a fluid-tight packing between two relatively moveable surfaces
IPC: F16J15/16
Filed: 1963-12-05
Abstract: 1,044,189. Packing for rotary-pistons. BORSIG A.G. and WANKEL G.m.b.H. Dec. 5, 1963 [Dec. 6, 1962; Sept. 12, 1963], No. 48014/63. Heading F1F. Packing for the piston of a rotary-piston compressor comprises a pair of ring-shaped sealing-strips or elements 1, 2 (Fig. 3, not shown), and a plurality of rectilinear sealing- strips or cross-pieces 35 - 39 lodged therebetween, the cross-pieces being made of an elasticallydeformable synthetic plastics material, e.g. a polyamide or ethylene tetrafluoride material, to effect sealing between their end faces and the adjacent sides of the elements 1, 2. Movement of the elements 1, 2 relative to the piston is prevented by pins 46, 47 which engage with the bottoms of grooves in which the elements are lodged. The elements may include gaps 33a, 34a between overlapping ends 33, 34. The gap in each element may be closed by a strip 50 (Fig. 4b, not shown) or strip 56 (Figs. 5a and 5b, not shown). Alternatively, the elements 1, 2 may be replaced by pairs of elements 58, 59 (Figs. 6a and 6b, not shown) having gaps 60, 61 situated remotely from one another. Similar packing may effect sealing between two bodies or members 14, 15 (Fig. 2, not shown) which are movable rectilinearly relative to one another, rectilinear sealing-elements 1, 2 (Fig. 1, not shown), being lodged in grooves 10, 11 in the member 14 with cross-pieces 3, 4, which are made of said material, situated therebetween. The cross-pieces are reinforced by rigid rods 8, 9. Chamfered edges 17, 18 are provided on the cross-pieces to prevent damage being caused by the edges 16a of an opening 16 in the member 15. The thermal expansion coefficient of the cross-pieces is greater than that of the member 14 to ensure sealing engagement between the ends of the cross-pieces and the sides of the elements 1, 2.

Title: Machine for shearing and stripping cable insulation
IPC: H02G1/14
Filed: 1973-10-16
Abstract: 1442223 Stripping conductors TEKTRONIX Inc 16 Oct 1973 [19 Oct 1972] 48154/73 Heading H2C An apparatus for shearing and stripping multi-conductor flat cable RC, comprises means, e.g. rollers 38 to feed the cable through co-operating sharp-edged discs 44, which slit the insulation between the conductors and splay the individually insulated conductors. Continued feeding causes the conductors to pass through holes 54 in a block 56 and project from its other side. Opposed shearing blades 60 on one side of block 56 and opposed insulation cutting blades 62 which are mounted on blades 60 and lie on the other side of the block are moved, via a linkage, by an hydraulic piston-cylinder 84. The path of the two pairs of blades is controlled by pins 64 mounted on blades 60 moving in right-angled slots 78 so that the two pairs of blades first move at right angles to the cable to sever the conductor ends and simultaneously sever the conductor insulation and then move parallel to the cable so that blades 62 pull the severed portions of insulation from the conductor ends. Suitable control arrangements and linkages cause the desired length of cable to be fed by rollers 38 and as shown in Fig. 7 raise the top die 44 and top roller 38 to allow the cable end to be removed when the shearing and stripping operation is complete.

Patent GB-1036540-A (GB)
Title: Bleaching wool
IPC: D06L4/30
Filed: 1964-12-09
Abstract: Wool, which may be in the form of fibres, tow, yarn or fabric, is bleached by saturating it with a first aqueous solution containing 1-10% by weight of an alkali or alkaline earth metal bisulphite, e.g. sodium, potassium or magnesium bisulphite, or ammonium bisulphite, contacting it for 5 seconds to 10 minutes with a second aqueous solution containing 0.001-10% by weight of an alkali or alkaline earth metal borohydride, e.g. sodium, potassium, lithium or magnesium borohydride, used in an amount to provide in contact with the saturated wool 0.05-7% by weight of the borohydride based on the wool, providing a pH of 1-8 in the immediate environment of the wool in the second aqueous solution, withdrawing the wool from the second aqueous solution within 10 minutes from the time it is contacted therewith and removing the borohydride from the wool.  Prior to treatment with the bisulphite solution the wool may be scoured with an aqueous solution containing a nonionic wetting agent, e.g. iso-octylphenyl polyethoxyethanol, containing 9 moles of ethylene oxide per mole of iso-octylphenol.  The bisulphite may be formed in the solution from metabisulphites, sulphites or sulphur dioxide in the presence of water and alkali ions at a pH of 1-8.  The wool may be immersed in bisulphite solution and all but 50-150% by weight of the solution expressed.  The bisulphite solution may have a pH below 8 adjusted with a mineral acid, e.g. sulphuric acid, or a lower aliphatic organic acid or sulphonic acid to provide the pH 1-8 in the environment of the wool since the borohydride solution is normally maintained at a pH above 8 for stability.  The borohydride solution may be agitated by moving the wool through it.  The borohydride solution may be removed from the wool by washing with water containing a detergent or by mechanically reducing the amount of the second solution it carries and then heating to 110 DEG -180 DEG F. for 10-30 minutes to decompose the borohydride followed by washing with water and drying at 110 DEG -180 DEG F.  The process may be carried out at 40 DEG -230 DEG F.

A cord ply for reinforcing resilient plastics or rubber, e.g. for reinforcing pneumatic tyres, conveyor belts or driving belts, comprises a number of parallel filaments 8 adherently held together by connectors 9 in the form of staple fibres extending transversely to the direction of the filaments 8 and which connectors do not touch each other for the greater part of their length, each connector extending on one side of the cord ply. Preferably, the connectors 9 have a much smaller cross-section perpendicularly to their length than the ply-forming filaments 8. Tangled dry fibres 9 are blown onto or applied in fleece form to the filaments 8 as they leave a dip bath. Slight pressure is applied to the fibres 9 by a roller or bar. Alternatively, a thermoplastic fibre fleece may be applied by heat softening between heated rolls before the filaments 8 are dipped or a non-thermoplastic fibre fleece, e.g. cotton, may be sprayed with adhesive and applied to the filaments 8 prior to dipping. In a modification, the staple fibres may be of manila hemp. Specified adhesives are emulsions or solutions of polymers or copolymers of organic vinyl compounds, more particularly those having functional groups. The filaments 8 may be multifilaments, monofilaments, yarns or threads and may be of natural fibres, glass fibres, metal wires or synthetic filaments, e.g. rayon or polyamide.
