Abstract: 1,121,560. Laminates. NEEDS Ltd., G. F. J. DANDRIDGE and W.R. CRAIG. 15 March, 1967 [15 Dec., 1965], No. 53262/65. Heading B5N. In a machine for manufacturing composite material, a slightly porous backing sheet 10, e.g. of hardboard, plywood or cardboard is secured to a layer of fibrous fabric 20 laid between two films 18 and 22, e.g. of thermoplastic resin or cellulose acetate, each of material capable of being softened or dissolved by a volatile solvent by pressure applied to the backing sheet after application of the solvent to soften or dissolve the films. The machine comprises rollers 11, 12 for conveying the piece of backing sheet 10 along a predetermined travel path, a cutter 25 for cutting suitable lengths of films and fabrics from continuous bulk supplies 19, 21, 23, and feeding rollers 14, 15, 16, 17 for feeding the films and fabric to positions adjacent the forward end of the piece of backing sheet. The cutting and feeding rollers are controlled through sensing means, e.g. photoelectric devices, responsive to the presence or absence of the sheet 10 at positions x and y. Guides 24 are provided for the films 18, 22 and fabric 20, and additional guides 26 are also provided for the film 22. Alternatively, the film 22 may be guided through a separate cutter, Fig. 2 (not shown). Feed of the films and fabric is initiated by the arrival of sheet 10 at the point x and the films and fabric are conveyed until they hang at positions p and q. Simultaneously, arrival of the leading edge of sheet 10 at point y halts the feed. The surface of the sheet 10 has solvent applied by rollers 29 immediately before contacting the film 18 and fabric 20 and drawing them, with a small overlapping edge, through rollers 31 which also serve to apply solvent to the fabric. Film 22 is then picked up at point q and the assembly passes through rollers 33 and 34 and is carried away by rollers 35, 36. When the trailing edge of sheet 10 passes the point y the cutters 25 are operated to sever the films and fabric. The roller pairs 14, 15, 16, 17 are coupled to drive means only during the initial feed of the films and fabric.

Abstract: 1364510 Driver valves CLAYTON DEWANDRE CO Ltd 16 Oct 1972 [19 Nov 1971] 53831/71 Heading F2F A manually operated brake control valve has an inlet 5, a delivery port 3, an exhaust chamber 7, oppositely disposed valve seatings 4, 6, and a valve element 10 engageable alternatively with the seatings and moved by hand operated means between a first position engaging one seating 4 to close off the inlet and allow communication between the delivery port and the exhaust chamber, and a second position engaging the other seating 6 to close off the exhaust chamber and allow communication between the inlet and delivery ports, a spring 17 urging the valve element towards the first position so that the valve element is only held in the second position by inlet air pressure exceeding a predetermined value. Spring applied brakes are held off when air passes from the inlet 5 to the outlet 3, the valve element 10 engaging the seating 6 and a control handle 19 being in a position D. When the inlet pressure drops, the spring 17 moves the element 10 against the seating 4 to exhaust the air and apply the brakes, the handle 19 moving to a position V against the detent 20. Subsequent increase in inlet air pressure does not reset the element 10 since the effective area under pressure is decreased to the area of the seating 4. Movement of the handle 19 to position D raises the element 10 via members 13, 14, 11 and a lost motion connection. For parking, the handle 19 is lifted over the detent 20 to position P and takes up the lost motion to force the element on to the seating 4 for brake application.
