Title: Die-casting
IPC: B22D17/32
Filed: 1974-10-08
Abstract: 1486475 Valves BUEHLER AG Gebr 8 Oct 1974 [8 Oct 1973 3 May 1974] 43464/74 Heading F2V [Also in Division B3] A control valve comprises a flow passage 141, a valve seat 12 and a co-operating sealing portion 131 on a valve member 11, such that, when the valve member 11 is moved, flow of fluid is prevented by a portion 133 of a flow-regulating portion 13 of the member until a portion 134 becomes operative to open up a fluid flow path of progressively larger area. The valve is used in the control of a die-casting machine in which a plunger 3 ejects molten metal from a chamber 2 into a mould cavity. The hydraulic system includes a gas-pressure source 7 connected to a cylinder 6 connected to a fluid-pressure source P. When a four-way electro-magnetic valve 81 is operated, pressure chambers 16, 17 are exhausted through a temperature-, and pressure-, compensated variable bleed 83 to a sump T. Initially, a cylindrical surface 133, Fig. 2, on a valve-spool 11 prevent flow of fluid from a line 91 to a line 92 controlling a piston 51 abutting the injection plunger 3. But as the spool 11 moves rearwardly due to the pressure reduction in the chambers 16, 17, a spherical surface 135 followed by a paraboloidal surface 134 allow fluid to flow. (There may be a small flow previous to this since the main initial sealing surface of the spool is the conical surface 131). The acceleration of the plunger is constant for 70-90% of the total time taken for the plunger 3 to complete its stroke. For the mould-filling part of the plunger stroke, the bleed 83 is short-circuited by operating an electro-magnetic valve 85 which causes the chambers 16, 17 to be connected directly to the sump, the valve 10 then being suddenly opened to its full extent set by a screw 24. (In modifications, the mould-filling phase is also at constant acceleration or, may be at zero acceleration). In the initial phase, the injection plunger 3 is moving the charge (already lying in the cylinder 2 to a constant depth) into a mass at the end of the cylinder as shown in Fig. 6.6. In the prior art, such massing has been done in such a way that an air-pocket is produced as shown in Fig. 5.6. In a modified circuit, the lines 91 and 92 are interchanged, the control fluid thus flowing past the spool head 13 in the opposite direction. In a final modification, the screw 24 is adjustable by a geared motor, the bleed 83 is remotely adjustable, a delay valve is provided to prevent pressure surges and the multiplier piston 5 is separate from the shot cylinder 4. Such a machine can be used in a centrallycontrolled set of machines. Pressure may be exerted on the metal while it is solidifying the mould.

The yarn 15 is introduced into a steam duct 2, the steam being introduced into the duct 2 by means of nozzles at the yarn inlet end, and further steam being introduced by means of openings or nozzles in the base of the duct, which openings or nozzles communicate with a steam chest 7 below the duct 2. The steam is introduced into the steam chest 7 at such velocity and pressure that the steam issuing from the openings or nozzles lifts the yarn and imparts a forwarding motion thereto. The steam is withdrawn at the yarn exit end of the duct. In a preferred embodiment, several ducts 2, 3, 4, 5 and 6 are positioned one above another, and the yarn passes through the ducts in zig-zag fashion. The yarn may be guided by rollers 17 driven at the same linear speed as the yarn. The base of each duct 2, 3, 4, 5 and 6 is preferably transversely corrugated whereby the yarn is conveyed on a turbulent flow of steam. After leaving the duct 6, the yarn is preferably passed through a water duct 12 in which the yarn is conveyed by the water and cooled thereby. The yarn is then passed via pressure rolls 43 and hot air blower 38 to a drier 36. The steam withdrawn from the ducts 2, 3, 4, 5, and 6 is preferably conveyed to the drier 36 and passed over steam-heated pipes 44 to issue through openings 45 into a duct 14. In a preferred embodiment, several yarns are steamed side-by-side, the ducts 2, 3, 4, 5 and 6 having adjustable side walls to accommodate the varying number of yarns. The steam is preferably introduced into the ducts 2, 3, 4, 5 and 6 and associated steam chests 7, 8, 9, 10 and 11 by means of boxsection nozzles extending the width of the ducts and chests respectively.

Abstract: 1328536 Data preparation BENDIX CORP 11 Sept 1970 [12 Sept 1969] 43656/70 Heading G3N A probe 12 is moved parallel to the X axis in a sequence of passes at programmed or manually selected intervals of Y, see Fig.6 (not shown) and remains in contact with a surface 14 of, for example, a turbine blade, the coordinates, in digital form, of a set of points on the surface 14, see also Fig. 2 (not shown), at predetermined spacing being passed to buffer storage 26. The latter is interrogated by computer 28 which feeds to tape punch 36 producing a numerical control tape 38 the coordinates of an optimised subset of points selected from the set according to the criterion that the distance from any point of the subset to the approximate midpoint of a chord joining the previous point of the subset to a subsequent point of the set be greater than a given tolerance. The optimisation iterates when a new point of the subset is determined, Figs.3, 4 (not shown). The distance is measured either perpendicular to the chord, in the Z direction, or perpendicular to the tangent at the initial point of the chord. The computer also controls the movement of probe 12 during scanning, the programme for movement and optimisation, which are carried out simultaneously, being displayed in Fig.7 (not shown). The set of points may be spaced at given increments of X, or alternatively of X + Z. The buffer store 26 comprises two sets (44, 46) Fig.5 (not shown) of registers, the latter storing coordinates during optimisation. A start switch (40), and a "ready" indicator, i.e. a bell or lamp are provided. The surface profile of the probe 12 may conform to the shape of a tool which will reproduce the surface 14 of the model 16. Movements of the probe, and housings 20, 22 in the coordinate directions are measured by linear variable differential transformers. The data may be recorded on a magnetic tape or disc.

Filed: 1967-09-28
Abstract: 1,166,359. Hydropneumatic springs. DAIMLER-BENZ A.G. 28 Sept., 1967 [30 Sept., 1966], No. 44280/67. Heading F2S. A hydropneumatic spring incorporates means for automatic compensation for leakage losses from the hydraulic operating chamber 4. The position of a piston 2, connected to the unsprung mass of a vehicle, controls a valve 10 for supplying hydraulic fluid from tank 17 via pump 9. For a predetermined " normal " vehicle loading the fluid flows back through a return pipe 18. On increased loading however the piston moves upwards and the valve 10 opens the connection to an hydraulic regulating chamber 8, applying pressure via spring diaphragm 12, secondary and primary pneumatic chambers 7 and 5 respectively to spring diaphragm 3 and restoring the piston to the normal position. When the loading is decreased the piston moves down and valve 10 connects chamber 8 to the return pipe 18 so reducing downward pressure on diaphragm 3 and restoring normal position. As leakage occurs from chamber 4 the piston moves up and valve 10 operates to apply pressure to chamber 8 and restore the piston to its normal position by deforming the diaphragm 3. Thus the pressure in chamber 5 is greater than in chamber 3 by the resilient restoring force of the diaphragm 3 and hydraulic fluid passes down through a throttled short circuit 16a to restore the volume of chamber 4. Alternatively if fluid in chamber 4 expands due to heating valve 10 acts to reduce the pressure in chamber 5 and the consequent bending of diaphragm 3 forces fluid up via 19 into chamber 8, to restore the volume of chamber 4.
