Title: Improvements in the means for wrapping a wire or other filament around a body
IPC: B65H81/00
Filed: 1941-10-06
Abstract: 548,482. Winding wire &c. on cylinders &c. BRIDGES, W. Oct. 6, 1941, No. 12873. Addition to 548,480, [Group XXII]. [Class 109] [Also in Group XXH] In an apparatus for winding a wire or other filament on a rotating body such as a tube or cylinder in which the tension is kept constant by passing the wire &c. from a supply over a rotatable drum associated with a brakeband and lever and under a jockey pulley on a downwardly biased lever so that variations in the tension of the wire &c. causes the jockey pulley to rise and fall and the brake lever to rock to vary the braking effort as described in the parent Specification, the brake and pulley levers are respectively provided with a cam and follower or vice versa the cam being so shaped that equal movements of the pulley lever at different stages in the range of movement result in different movements of the brake lever. The descent of the pulley lever through its lower stages results in a substantial increase in the braking effort so that a length of slack wire which must be rewound on to the supply drum when winding is recommenced is avoided and the wire from the start of the operation is wound at the required tension. The wire &c. 25 to be wound on the rotating cylinder 7 passes from supply 24 over brake drum 39, then under jockey pulley 40 on weighted lever 47, over idle pulley 41 to cylinder, these parts being mounted on a saddle 2 traversed by a hand-operated lead screw. The brake lever 54 which is pivoted at 55 and connected at 53, 55 to the ends of the brakeband 36 carries a cam 71 which is slotted so as to be adjustable on bolts 73 and co-operates with roller 58' adjustable in a slot 74 on the lever 47. The upper portion of the edge of the cam is substantially vertical but the lower portion is curved away from the pulley 40 so that small fluctuations in tension result in small variations in the braking effort, but if the tension drops considerably the brake lever rocks through a considerable angle and effects a substantial increase in the braking effort. The lever 54 is biased by a weight 75. A spring-pressed mushroom headed spindle 77 assists the upward movement of the lever 47 to prevent bounce during the initial stages of winding.

Patent GB-1355373-A (GB)
Title: Porous materials derived from tetrafluoroethylene and process for their production
IPC: C08J9/00
Filed: 1971-05-05
Abstract: 1355373 Laminated products W L GORE & ASSOCIATES Inc 5 May 1971 [21 May 1970] 13178/71 Headings B5B and B5N [Also in Divisions B2 C3 and H1] A laminate comprises a first shaped article bonded to a second shaped porous polymeric article the polymer containing units derived from tetrafluoroethylene and the porous polymer having a microstructure (i.e. which cannot be resolved with the naked eye) characterized by nodes interconnected with fibrils and having a matrix tensile strength (i.e. max. tensile strength multiplied by the ratio of the specific gravity of the solid polymer to that of the expanded, porous polymer) of at least 7300 p.s.i. in at least one direction. The porous polymer is made by forming a shaped article of the polymer containing a lubricant by a pasteforming extrusion technique, removing the lubricant and stretching the shaped article at an elevated temperature and at a rate exceeding 10% per second. The expansion may be effected in one direction or biaxially. The polymer may be a homopolymer of tetrafluoroethylene, or a copolymer thereof with ethylene, chlorotrifluoroethylene or hexafluoropropylene and the laminate may be in the form of a film, tube, filament or rod. The porous polymer may be compressed, and may also contain asbestos, carbon black, mica, silica, titanium dioxide, potassium titanate or a polysiloxane. In the examples a paste of the tetrafluoroethylene polymer with mineral spirits or kerosene was extruded to form a rod, film or tube which were dried to remove the spirits or kerosene, the articles were then expanded by stretching while being heated and held in the extended condition while being cooled. Fig. 2 shows a machine for making continuous expanded film by feeding polytetrafluoroethylene film 13 from roll 14 on to heated roll 15 then to heated roll 16 which can run faster than 15, gap A is adjustable; the stretched film goes on to hot roll 17 (running at same peripheral speed as 16) where it is heated to 370 C. to produce amorphous locking (i.e. the amorphous content of the polymer is increased by the heating and this inhibits slip along the crystal axes of the crystallites); roll 18 controls the residence time of film on 17 which is then fed to water-cooled roll 19 and wound on roll 20. The film may be expanded instead by vacuum forming or moulding, and tubes may be expanded by feeding compressed gas therein. The laminate is formed in Example 9 by heating two films which have been expanded as above (the films being placed in contact with and at right angles to each other); and in Example 11 by impregnating one expanded film with epoxy resin and a second film with a solution of metaphenylene diamine, and heating the two films as above.
