Patent GB-759625-A (GB)
Title: Ornamentation of textiles
Inventor: BENTHAM RUSSELL
IPC: D06Q1/08
Filed: 1953-10-20
Abstract: Coloured pattern effects are produced on textiles made wholly or to a substantial extent of natural or regenerated proteinaceous substances other than silk by applying a mechanized pressure action in selected areas, followed by dyeing, treatment with a resist for the dyestuff also being effected before or after the application of the mechanical pressure action or together with the dyeing operation.  The treatment is applicable to textiles of wool and regenerated protein fibres in the form of woven, knitted or matted fabrics, slubbings, rovings and yarns, and the textile may be pre-dyed or preprinted.  Both the treatment with the resist and the dyeing operation may be locally applied.  As applied to slubbings, the dyeing operation may be effected before or after they are spun into yarns and woven into fabrics.  Further effects may be obtained by applying a second dyestuff, preferably from the same batch as the first dyestuff, whose acceptance by the fibre is not prevented by the resist.  The steps of the process may be repeated.  The mechanical pressure action may be applied by a press, brush or engraved calender, or by the means described in Specification 752,191 whereby the selected areas are also compressively shrunk. Preferably the mechanical pressure means is heated and the textile treated therewith in the wet condition. Specified resists are synthetic tanning agents, sulphurized phenols as described, for example, in Specification 640,421 sulphonated sulphurized phenols, sulphonated phenols and naphthols, formaldehyde derivatives of naphthalene sulphonic acid, bisulphite derivatives of glyoxal, and an acetylation or chlorination treatment.  Dyeing may be effected with level dyeing acid, acid milling, chrome, premetallized, direct, solubilized vat and fluoroescent dyestuffs, preferably di- or tri-sulphonated dyestuffs.  Numerous examples are given.  The Provisional Specification refers also to the treatment of proteinaceous films.  Specification 759,595 also is referred to.

Title: Improvements in reciprocating stock feed
Inventor: POWERS WALTER PALMER
IPC: B23Q7/04
Filed: 1955-10-17
Abstract: 779,572. Feeding metal strip. TODD, C. Oct. 17, 1955, No. 29584/55. Class 83 (4). In a strip-feed mechanism having a reciprocating gripper 12 and a clamp 34 for preventing reverse movement of the strip 14, the gripper 12 is reciprocated by a toggle 16, 17 which at or near its dead-centre position actuates the clamp 34. The gripper 12 is pivotally mounted on a block 10 sliding on guides 11 and is reciprocated by a link 22 driven from the crankshaft of a press and acting through the toggle 16, 17. As the toggle passes through its deadcentre position at the end of the feeding stroke a cam 39 on the toggle link 17 engages a block 40 reversibly secured to a lever 32 to raise the lever 32 and to cause the clamp 34 to grip the strip. When the toggle is moved in the reverse direction, a catch 28 frictionally mounted on the hub 24 of a bell-crank 21, one arm 16 of which forms part of the toggle, engages under a lug 31 on one end of the lever 32 to hold the clamp 34 closed. When the feeding stroke is started the catch 28 is moved to allow the lever 32 to drop to release the clamp 34. If the press is provided with a strip guide it is necessary to delay the gripping action of the clamp 34 to allow the guide to centre the strip. The block 40 is reversed and at the end of the feeding stroke the cam 39 depresses and passes under a spring loaded plunger 46, Fig. 8, in the block without raising the lever 32, but at the commencement of the return stroke the cam 39 acts on the plunger 46 to raise the block 40 to cause the clamp 34 to grip the strip 14.
