Title: Improvements in or relating to pressure casting machines
Inventor: LINKE REINHOLD
IPC: B22D17/32
Filed: 1969-01-03
Abstract: 1,254,324. Casting metals. DRUCKGUSS HEIDENAU VEB. 3 Jan., 1969, No. 442/69. Heading B3F. [Also in Division F1] The ram of a pressure-casting machine is driven by a two diameter piston 1, 1a which completes part of its stroke at one speed when hydraulic fluid from a pump 15 is supplied to a chamber 9 and the remainder of its stroke at increased speed when the output of an accumulator 19 is supplied to the chamber 9. When movement of the piston 1 is stopped due to the mould becoming full, an annular piston 3, 3a surrounding the small diameter piston portion la continues to move in the original direction due to its inertia. Thus hydraulic fluid in a cylinder space 7 is displaced by the annular piston portion 3a into a second pressure accumulator 13, the charging pressure of which is controlled by a valve 22. To return the pistons 1, la and 3, 3a, a changeover valve 14 is moved to the position shown, thereby exhausting chamber 9 and pressurizing a return chamber 8. The change in speed during the forward stroke is caused when a switch 20 is operated by a rod 21 movable with the piston 1, 1a. Operation of the switch 21 causes opening of a valve 18 which allows the accumulator 19 to discharge at a rate determined by an adjustable valve 17.

Title: Method of electrolytic oxidation of aluminium alloys
IPC: C25D11/16
Filed: 1956-01-05
Abstract: 803,357. Anodizing aluminium alloys. SCHMIDT G.m.b.H., K. Jan. 5, 1956 [Jan. 7, 1955], No. 469/56. Class 41. Aluminium alloy articles such as pistons and cylinders for I.C. engines are electrolytically surface-oxidized by a process in which they are first pre-treated in a pickling or etching bath to remove those alloy components which would hinder electrolytic oxidation and then are mechanically treated to compact and/or smooth the porous and rough pickled surface. The pickling may be effected either chemically or electrolytically in nitric acid to which hydrofluoric acid may be added, followed, if desired, by heat treatment to remove occluded hydrogen formed during the pickling prior to mechanical compacting as by a gentle pass through a rolling mill or in the case of cylindrical members by the insertion of a slightly tapered mandrel. If a hard and strong surface layer is required, there may be used dilute sulphuric acid at a temperature between 0‹ and 3‹ C. with an applied voltage of 50 volts or more and a current density of, say, 7 amps./sq. dm.

Title: Improvements in volumetric liquid meters for measuring small rates of flow
IPC: G01F3/16
Filed: 1962-01-05
Abstract: 920,694. Liquid meters; liquid pressure engines. COMPAGNIE DES COMPTEURS. Jan. 5, 1962 [Jan. 6, 1961], No. 501/62. Classes 69 (1) and 69 (2). A volumetric meter for small liquid flows comprises two measuring chambers 17 and 18 on either side of a double-acting piston 2 to each of which liquid is admitted alternately by a first valve 8 or 9 and discharged by a second valve 9 or 8 which is fast to the first, reversal of the valves and application of them to their seatings being effected at each end of a piston stroke by magnetic means. Liquid enters the meter at 13 and flows to and from the chambers by way of passages 21, 20 and 22 or passages 15 and 16 to the outlet 14. Packing-rings are provided for the piston at 6 and/or its rod 3 at 12 and bearings for the valve rod 7 at 10 and 11. The valves 8 and 9 comprise resilient toroid rings 23 which are held on metallic hubs 24 by peripheral rings (not shown). A rack 3a on the piston-rod 3 meshes with a toothed sector 4 on the periphery of a ring magnet 30 which has 6 poles N and S spaced circumferentially as in Fig. 6. Within the ring is pivoted a circular magnet 5 having similarly spaced poles N and S, and an eccentric finger 5a which co-operates with a fork on the valve rod 7. When the piston 2 arrives at one or other end of its travel the poles on the ring 30 travel over and just beyond like poles on the magnet 5. Magnetic repulsion then causes the magnet 5 to turn away in the opposite direction to a position such as that shown in Fig. 6, thereby operating the valves. Reverse motion of the piston again brings like poles into proximity and the motions of the magnet 5 and the valves are reversed.
