Title: Controlling the tension of stock withdrawn from a coil
IPC: B21C47/00
Filed: 1976-08-06
Abstract: 1501069 Unwinding; tension control ANTEK INC 6 Aug 1976 [29 Aug 1975] 32831/76 Heading D1J A tension control means for stock S, Fig. 1, being unwound from a reel C comprises mounting the reel C such that it can move in the direction Sf in which the stock S is being withdrawn from the reel, biassing the reel in the opposite direction by a force 13, 38, 39 and decreasing or braking action on the reel C to an extent dependent on the displacement of the reel C in the direction Sf so as to maintain the tension substantially equal to the biassing force. In Fig. 1 the reel C is mounted for rotation in a carriage 11 that can slide to the left on guide rails 25, 26 due to a pull Sf in the stock S. The carriage 11 is biassed to the right by a weight 38 on a cable 39 passing over pulleys 41 and 42, Fig. 2. The reel C Fig. 2 is mounted on, and rotates with, a shaft 51 that includes a brake disc 61. Mounted on and moving with the carriage 11 is a brake operating mechanism 15 that is coupled by means 68 to disc brakes 14 acting on the disc 61. The brake mechanism 15 is preferably of the hydrostatic pressure type. Also mounted on the carriage 11 is a rotatable cam 78 pivoted at 79. A lever 81, rigid with the cam 78, is pivoted at 83 to an adjustable link 82. The arrangement is such that when the carriage 11 moves to the left the arm 81 is caused to rotate clockwise and this in turn rotates the cam 78 clockwise. Rotation of the cam 78 actuates a plunger 71 that in turn actuates the brake operating mechanism 15 and thus the disc brakes 14.

Abstract: 1405974 Hydraulic presses; caulking; trimming EXPERIMENTALNY NAUCHNOISSLEDOVATELSKY INSTITUT KUZNECHNO-PRESSOVOGO MASHINOSTROENIA 12 July 1973 33219/73 Headings B3H B3U and B3W [Also in Divisions B5 and G3] An hydraulic press for applying a pulsating load has a working piston-cylinder 3, 2 whose upper space 6 is supplied with pulsating hydraulic pressure from a main 9 through a pulsator 10 and. whose lower space 7 is continuous connected to an accumulator 28 through a adjustable throttle 27 to enable the applitude of oscillation of the piston to be controlled. The pulsator 10 has a valve 13 urged by a piston 16 under air pressure to a position wherein the main 9 is ducted to the upper space 6. When the pressure rises after a working stroke the valve lifts to connect the main 9 to drain 11. The differential pressure on a pusher 14 causes the pusher to open the valve fully after the initial pressure drop. Finally the air pressure in the space 22 moves the piston 16 to close the drain and the cycle is repeated. The accumulator 23 is supplied with gas pressure, e.g. nitrogen. from a main 32 and liquid pressure from a main 30. The force of the press is determined by the air pressure in the space 22, the frequency of oscillation by the opening of the throttle 20 between the main 9 and the pusher space 18 and the amplitude of oscillation by the throttle 27 opening. The press may be used for producing stepped pipes, caulking and stretching.

In a long-wave radar system a continuous carrier is pulse-modulated and the Doppler changes in frequency of the reflected wave from a moving target are used to derive both the range and speed of the target. The speed is determined by known methods while the range is indicated in the first embodiment on a C.R.T. or in the second embodiment on an illuminated scale. In the first embodiment, the radar information is obtained from a selected received side-band, the Doppler frequency change of which, detected at 10, is used to modulate at 13 a carrier signal from the transmitter at 5. The latter is then applied, with the received signal, to a synchronous detector 15, the output of which is applied to the Y-plates of a C.R.T. 16. The X-plates of 16 are provided with a time base from the transmitter pulse modulation circuit 3, and the deflection, d, is proportional to target range. In the second embodiment, not shown, the CRT is replaced by a system of lamps, each of which represents a given target range, and which are energized from a continuouslyrotating switch controlled from the transmitter pulse circuit.

A foamed homopolymer or copolymer of an unsaturated compound is prepared by a process which comprises mixing an aqueous dispersion of the homopolymer or copolymer with a compound having at least two groups, each of which contains an electron attracting group in an aposition to a -CH- radical and each of which is bound to the residue of the molecule via an oxygen or nitrogen atom, and a reaction product of a polyamine and carbon dioxide and treating the mixture with an aldehyde to bring about condensation with the liberation of carbon dioxide. Suitable homo- or copolymers include those which have been obtained by homo- or copolymerizing unsaturated compounds, e.g. vinyl acetate, homopolymer and copolymers with dibutyl maleate or butyl acrylate, or styrene/butadiene copolymer. Fillers such as chalk, talc, heavy spar, gypsum, lithopone, mica, quartz powder, titanium dioxide, sand, powdered asbestos, wood powder, cork powder, man-made staple fibres, glass fibres, pumice gravel, asbestos fibres or mixtures thereof may be added to the dispersions. Suitable groups containing "activated hydrogen" are, for example, #-ketoacyl groups such as acetoacetyl, cyanoacetyl, malonyl and nitrophenylacetyl radicals, and, generally, acyl groups containing methylene groups activated by adjacent electron-attracting groups. Compounds containing such groups may be derived from polyols, polyfunctional, primary or secondary, aliphatic, aromatic or heterocyclic amines, polyesters of polyfunctional alcohols with polyfunctional acids and polyethers which may be homo- or block polymers derived from, for example, ethylene oxide, propylene oxide or tetrahydrofuran; the said compounds may also be copolymers formed, for example, by copolymerizing vinyl or allyl esters of #- ketocarboxylic acids, polymerizable dicarbonyl compounds, or unsaturated esters of malonic acid with one or more other copolymerizable monomers. Reaction products of polyamines and carbon dioxide are carbamates, and primary or secondary amines which are at least bifunctional may be utilized. Formaldehyde as a 40% aqueous solution is the preferred aldehyde but higher aldehydes, e.g. acetaldehyde and crotonaldehyde may also be used. Low boiling solvents may also be used concomitantly as expanding agent. Blocks, webs, sheetings and shaped articles may be obtained. Uses:-Insulation against noise and heat, may be directly applied to ceilings, walls and floors and may be used in cavities.
