Title: Press having a device for preventing uncontrolled load relief  in a frame and drive system of the press
IPC: B21D28/00
Filed: 1973-09-28
Abstract: 1436531 Shearing; punching L SCHULER GmbH 28 Sept 1973 [29 Sept 1972] 45478/73 Heading B3W [Also in Division F2] A press has an hydraulic damper device, for preventing uncontrolled recoil of the press structure at the moment when a press tool breaks through a workpiece, comprising a cylinder and a piston connected, one to the frame and one to the ram of the press, the piston dividing the cylinder into two liquid-filled chambers normally interconnected to allow flow between the chambers but with means for interrupting the flow and means providing an alternative, throttled liquid path during such interruption. As shown, a pair of pistons 18, each connected to the ram move in cylinders 21 during a working stroke each causing liquid to flow from a chamber 20 into chamber 24 of adjacent cylinder 22, a floating piston 23 to rise and liquid to return from chamber 25 to chamber 19. At a point in the stroke predetermined by adjustment of a stop 28 this liquid exchange stops and liquid is forced to flow through line 11 throttled at 12. Liquid is returned to chambers 25 via a non-return valve by-passing a prepressuring valve 27. A relief valve 26 and accumulator 14 maintain an acceptable pressure level. The period during which the throttles function may be varied by means of shut-off valves 10 actuated by cams 16 on a shaft forming part of the press drive. In a simplified embodiment, Fig. 1 (not shown), the cylinders 22 are omitted and the check valves 10 are located in lines normally allowing liquid flow between the upper and lower chambers of the main cylinders.

Abstract: The adhesive properties of polyethylene and cellulose are improved by the addition thereto of a carboxylic acid or anhydride modified polyethylene wax having a density of at least 0.88 and a molecular weight of from 1000 to 5000. Specified modified polyethylenes are made by heating polyethylene waxes, which have been made by pyrolysis of high density polyethylene, with maleic acid, maleic anhydride and thioglycolic acid.  The Specification describes also the preparation of coating compositions based on the above modified polyethylene waxes, the modified wax being either dissolved in a solvent, e.g. toluene or mineral spirits, or suspended in water containing morpholine and oleic acid.ALSO:The adhesive properties of polyethylene films and cellulosic sheet materials, e.g. paper, cardboard and corrugated board, are improved by coating them with a carboxylic acid or anhydride modified polyethylene wax having a density of at least 0.88 and a molecular weight of from 1000 to 5000. Specified modified polyethylenes are made by reacting polyethylene wax with maleic acid, maleic anhydride and thioglycolic acid.

Abstract: 1491512 Feeding sheets AGFA-GEVAERT AG 7 Nov 1974 [8 Nov 1973] 48199/74 Heading B8R The passage of photographic emulsion carriers 13, Fig. 2, into a treatment tank is sensed by a flap 1, Figs. 1 and 2, pivoted at la, 1b, and kept in a vertical position by gravity when not engaged by a carrier. The carrier engages the flap below the pivots and swings it counterclockwise as viewed in Fig. 2, so that a screen 1c on the flap interrupts one or both light paths from lamps as 3 to photo-receivers 4, 4a. The lower edge of the flap is inclined upwards towards the centre as at ld, 1e, so that the carrier is engaged by the flap only at its lateral edges when the flap is fully deflected. Alternatively, half of the lower edge may be horizontal, or the edge may be straight and inclined. The photo-electric detector may be replaced by a mechanical switch or a plurality of oscillatory circuits responsive to the nearness of a piece of soft iron on the flap. The degree of inclination of the flap can be detected and this gives an indication of the width of the carrier, while the duration of a signal indicates the length. The sensing means may control the introduction of replenishing liquid into the treatment tank.

Abstract: 1482081 Press control system SCIAKY ELECTRIC WELDING MACHINES Ltd 16 Oct 1974 [19 Oct 1973] 48781/73 Heading B5F [Also in Division B3] A control system for a clamp or press with a movable platen has means to apply a momentary impulse to the platen to move it to the clamping or pressing position and means to apply a clamping or pressing force fractionally before the clamping or pressing position of the platen is reached. The clamp or press may be used for resistance welding and the control system reduces the impact between a workpiece and an electrode. The press or clamp may be pneumatic or hydraulic. The platen is driven by a piston 10 above which compressed air is supplied through a spring-loaded poppet valve B and a valve S 1  to initiate a stroke. The valve B closes automatically as the piston moves downward to apply the momentary impulse and the piston and platen move under their own inertia. At or near the clamping or pressing position a valve S 2  connects line 16 to the compressed air main to apply pressure to the piston. The valve S 2  is operated by an adjustably positioned switch which may also energize a timer for the resistance welding operation.
