Abstract: 690,117. Hydraulic presses ; valves. GREEN, J. C. C. June 21, 1950 [June 28, 1949], No. 15456/50. Classes 69 (ii) and 135. A hydraulic control system for automatically controlling the ram of a press producing, e.g. moulded plastic articles, comprises a control valve having a cylinder 33, Fig. 4, slidably mounting a leaky piston 34 having a reduced diameter portion 34a seatable on a seat 35a to control the flow of a pressure liquid between an inflow port 36 and an outflow port 36a, and at least one loose ball pilot valve 45 removable from its seat by a cam mounted on a shaft rotatable by a tipping trough to open a passage 38 in the cylinder cover 35 to sump. In the system, two such valves are arranged in a tank 18, Fig. 1, so that one is open whilst the other is closed. One valve 24 being associated with two pilot valves 51, 50, Fig. 3, operable respectively by cams 47, Fig. 4, and 47a, Fig. 4a, mounted on shafts 23, 22 connected to tipping troughs 20, 21, and the other being associated with a pilot valve 52 operable by a further cam 47 mounted on the shaft 23. The troughs 20, 21 are supplied at a fixed rate through a calibrated nozzle 28 with water withdrawn from the tank 18 by a pump 29. A main pump 17 withdraws liquid from the tank 18 to constantly supply balancing rams 15, 16 and the inlet 36 of the valve 25 whose outlet 36a is connected by a line 55 to the ram cylinder 14. The ram cylinder being connected to the tank 18 through a line 53 and the valve 24. With the ram 13 at the top of its stroke, the valve 25 is open and the valve 24 closed whence pressure liquid is supplied to the cylinder 14 to urge the ram 13 downwards in opposition to the rams 15, 16 ; the ram reaching the bottom of its stroke prior to the troughs 20, 21 being filled to permit the carrying out of the pressing operation. On the troughs being filled they overbalance to rotate their respective shafts and so operate the pilot valves. The pilot valves 50 being opened first to momentarily open the valve 24 to permit the slight lifting of the ram 13 and the escape of gases from the dies. The pilot valves 51, 52 being subsequently operated to open the valve 24 and close the valve 25 whence the ram cylinder is exhausted of liquid and the rams 15, 16 urge the dies apart. On the upward movement of the ram 13 the troughs are returned to their upright positions by a rod 30 engaging the ends of levers housed in a box 32 so that the press is ready for the next cycle of operations. The invention may be applied to a press having a movable lower die or to one with a movable upper die in which the opening of the dies is effected by springs whence only one control valve is required. The inlet of this valve being connected to the ram cylinder to effect exhaust therefrom to the tank, the ram cylinder being connected directly to the pump 17.

Abstract: 632,442. Vaporization coating. NOYES, R. C., (Libbey-Owens-Ford Glass Co.). June 12, 1947, No. 15547. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 18. 1948.] Drawings to Specification. [Class 93] [Also in Group XX]  A surface is coated with quartz by heating the quartz in intimate contact with a stable solid metallic oxide on or in a heat-radiating support body in a high vacuum and depositing the evaporated quartz on the surface. The oxides of Al, Th, Be, Mg, Ca, Sr, Ba, Ti, Zr, Li, V, Cr, Mo, Ta, W, Na, K, U, Fe, Mn, Co, Ni, Cu, Pb, Sn, Bi, Ce, and Zn may be used and applied in the following ways :-(a) thermally evaporating the oxide and exposing the quartz to the vapour, (b) coating the quartz with the metal and converting the metal to oxide, (c) coating the quartz with a powdered oxide by a tumbling action, (d) intimately mixing powders, (e) treating the quartz with compounds which yield the oxide on heating e.g. hydroxides, nitrates, acetates, formates, carbonate, ammonium vanadate, ammonium tungstate, or higher oxides, and heating, (f) enclosing the oxide in quartz tubes. This coating may be formed by a preliminary heating or as a result of the final heating. The treated quartz is supported and heated electrically above 1500‹ C. in a high vacuum e.g. 10-5 mms in a thoria crucible or a coil, e.g. of W, V, or Mo, and the evaporated quartz deposited on the desired surface supported in the vacuum. Five per cent or generally less than one per cent of metallic oxide is sufficient. In an example a first coil surrounding silver is heated in an evacuated container in which a glass sheet is supported so that the latter is silvered, then second and third coils enclosing Al 2 0 3  are heated so that quartz contained in a fourth coil is coated, and finally the fourth coil is heated so that the quartz evaporates and coats the silvered sheets. The quartz may provide a protective or low reflection coating.

Abstract: 273,275. Holveck, J. E. June 28, 1926, [Convention date]. Crank-actuated pumps; stroke, varying; regulating delivery by opening suction valves.-A constant speed pump with variable delivery comprises two parallel crank shafts 19, 21 pivotally connected by rods 20, 22 to a crosshead 17 carrying the pump-plunger 12. The shaft 21 is driven by a gear-wheel 28 and carries a pinion 29 driving a gear wheel 30 loose on the shaft 19. An arm 31 rotatably mounted on the shaft 19 carries a fixed stub shaft 32 on which a spur wheel 33 is rotatably mounted so that it meshes with an internal gear on the wheel 30 and with a spur wheel 34 fixed to the shaft 19. The other end of the arm 31 has a stub shaft 35 rotatably mounted thereon and carrying a fixed spur wheel 36 meshing with the internal gear 30 and with the spur wheel 34. The arm 31 carries an extension 39 connected by a rod 40 to a piston in a cylinder 42 open to the delivery pressure of the pump. The piston is held down by a spring 44 arranged between a fixed crosshead 46 and a crosshead 45 on the piston. When the delivery pressure increases, the piston is forced up and rotates the arm 31, thereby changing the phase relation of the crankshafts and reducing the stroke of the pump plunger. To unload the pump when the stroke has been reduced to a minimum, the suction valve is held open by a cam 63 which is oscillated by rack and pinion 50, 51 driven by the spur wheel 36. Normally the cam rise is away from the valve stem, but when the delivery pressure has raised the crosshead 45 a certain amount, a switch in a solenoid circuit is opened and a spring operates mechanism which rotates the cam shaft 180‹ and brings the cam rise into contact with the valve stem, so that the valve is opened. In another form, the crankshafts 19, 21 are connected to separate plungers working in the same pump chamber, so that when they are rotating in phase the output is a maximum, and when in opposite phase the output is a minimum.
