Title: A new or improved control system for moulding machines and other purposes
IPC: G05G5/02
Filed: 1942-03-23
Abstract: 554,051. Moulding machines ; hydraulic presses ; valves. PNEULEC, Ltd., and COWLAM, K. W. March 23, 1942, No. 3803. [Classes 69 (ii) and 135] [Also in Groups V and XXVI] A control system for moulding- machines and other systems comprises a rotary valve 17 mounted on a spindle 16 and adapted to control ports leading from a source of fluid under pressure to a number of work cylinders or the like which are brought into operation sequentially so as to carry out a number of operations to complete the moulding of an article. The valve shown is adapted to be given eight movements of 45 degrees each by means of an operating-handle 23, Fig. 2 (not shown), provided with a sleeve 22 fitted with arms 27 carrying pivoted pawls 28a, 28b adapted to engage notches 29 in a collar 30 attached to the valve disc 17. The pawls are connected by a spring 31 and a cam 32 controls the pawls so that only one engages a notch 29 at a time. Normally the handle 23 is held in a central position by a spring detent which is released to permit actuation of the handle which for a complete operation of the machine is normally given eight clockwise movements of 45 degrees from its central position to which it is returned after each movement. If, however, it is desired to repeat a prior operation the handle can be moved counterclockwise when the pawl 28b effects the motion instead of the pawl 28a which is rendered inoperative by the cam 32. The valve cannot be given this reverse movement when it has reached the final or exhaust stage as the notch 29 in this position is replaced by an incline 34. The mould may be jarred by operation of a valve 12 under control of a cam 13, which may also operate a piston 15 for forcing lubricating oil to the working parts. The valve spindle is fitted with a pointer 19 which moves over an indicating disc marked to correspond with the nature of the operation being performed. Starting from exhaust the sequence is actuation of clamps, inversion of the mould, the raising of parallel beams to support the inverted mould, equalizing the position of the beams and locking same and releasing the clamps, actuating a vibrator or the table, slow withdrawal of the pattern during vibration, rapid completion of the withdrawal, and finally connection of all parts to exhaust.

Filed: 1966-02-01
Abstract: 1,091,822. Making composite sheets; rolling; welding by pressure. REVERE COPPER & BRASS Inc. Feb. 1, 1966 [Feb. 1, 1965], No. 4376/66. Headings B3A, B3M and B3R. A process for bonding an aluminium or aluminium based alloy sheet to a stainless steel sheet without the necessity to remove the surface layer of oxide from the sheets comprises heating the sheets in contact in a non-oxidizing atmosphere to a temperature in the range 900‹ to 1050‹ F. and passing the sheets between rollers also within the atmosphere to compress them and cause the aluminium sheet to flow relative to the stainless steel sheet, the composite sheet so formed being further heated to a temperature within the range 650‹ to 850‹ F. to produce a bond between the plates by diffusion of the metals. The bonding is between the stainless steel sheet and the clean non-oxidized surface of the aluminium sheet exposed by cracks in the oxide surface when the sheet flows. The relative flow may be increased by using different roll speeds, different surface finishes on the rolls or different lubricants between the rolls and the sheets. Initially the aluminium sheet may be smaller than the steel sheet.
