Title: Improvements in or relating to slip-hooks and like devices
IPC: B66C1/34
Filed: 1945-05-07
Abstract: 591,379. Slip hooks. BLACK, J. May 7, 1945, No. 11532. [Class 89 (ii)] Slip hooks, particularly those for use in towing or for releasing life-belts, rafts or floats, have the hook member formed on one end of a lever, near the pivot, the other end of the lever being held against rotation by a stop eccentrically carried by a pivoted release member operated manually or automatically. The hook 1, Fig. 1, is the short arm of a lever, pivoted at 3 in a link 4 having an eye 5, the longer arm 2, in the secure position, is held by a crank pin 7 movable to release position by a hand wheel 8. Excess movement of the lever 2 when resetting the hook is prevented by a fixed stop 6. In a modification, the hook is closed by being pivoted at one end 3, Fig. 3, the free end being releasably retained by the crank pin 7. In a modification for heavier loads, the longer end of the hook lever is locked by a lug on the pivot of a separate lever itself locked by a crank pin. In a further form similar to that shown in Fig. 3 the crank pin is rotatable by an arm lying alongside the link 4 in the secured position in which accidental release may be prevented by a ring sliding on the link over the lever end. In another form opposed to the release crank pin 7, Fig. 9, is a resetting pin 7<1>, the hook being returned to strike this, for bringing the pin 7 back into locking position, by a spring 6. When the crank is rotated by an arm this may be operated from a distance by a rope, or release may be affected automatically in the case of a raft &c. by a float. A number of lifebelts, floats &c. may be released simultaneously by disposing their slip hooks in line so that the crank pin of each is on a common spindle.

Abstract: 769,705. Coating wires. PLASTI-CLAD METAL PRODUCTS, Inc. April 23, 1954, No. 11860/54. Class 140. A method of continuously coating a filament consists in the straight line drawing of the filament to be coated through a viscous coating material then into a nozzle then through a rigid walled outlet orifice, the nozzle being yieldably supported for vibratory movement of its orifice and transversely of its longitudinal axis, whereby the viscous material between the filament and orifice wall transmits vibrations from the filament to the nozzle without substantial displacement of the filament from its axially centred position in the orifice. The filament 11 is fed from a reel round a guide roller to an inlet of a coating chamber 13. The inlet 23 has an end plug 25 with a hole tightly fitting the filament. After passing through the material in the coating chamber the filament passes through a nipple 29 secured by clamps 30, 31 to the end wall 28 of the chamber and then through a tapered nozzle 35 flexibly secured to the nipple by a hose 33 secured by clamps 32, 34. The coated filament passes through a drying chamber, past a cooling zone to a winding reel. The coating material comprises plastics including synthetic resins, natural or synthetic plastics, cellulose and its derivatives, protein plastic substances, petroleum plastic derivatives or combinations to regulate resiliency, stiffness, bactine growth, fungus growth, water-proofness, melting or softening points or strength factors. Particles may be added to the coating material, the particles may be pumice, carborundum, or other abrasive, quartz, sifted sand, wood flour, or walnut shell flour. The particles may provide a rough surface, or give an ornamental coating with or without the addition of pigments; be heat resistant, luminous or reflective.
