Title: Improvements in or relating to safety devices for hydraulic brake or control devices
IPC: B60T11/32
Filed: 1955-06-13
Abstract: 770,105. Hydraulic brakes. ERREN, R. A. June 13, 1955 [June 21, 1954; April 25, 1955], No. 16930/55. Class 103 (1). In an hydraulic brake system, particularly for motor vehicles, the master cylinder has a main piston b which normally pressurizes fluid in the space below it and forces such fluid through ports m into a plurality of housings f and therefrom by pipes d1, d2, d3 and d4 to the individual brake cylinders. If there should be a breakage in any of the pipes d1 to d4, so that the main piston b is moved downwards beyond its normal travel x to the part y, it engages piston rods i so that pistons g are moved downwardly beyond the ports m. The fractured pipe is thus cut off from the space below the main piston and the other pipes are pressurized by the auxiliary pistons. Loss of fluid from the pipes d1-d4 is made up from a tank n past non-return valves r, the tank being subdivided into chambers P0, P1 ... P4, the level in each chamber being advantageously shown in a light glass. In the arrangement shown in Fig. 5, the reservoir chambers P1-P4 are incorporated in the housing a and the auxiliary pistons g have an axial central passage adapted to be sealed by a plate 7, connected to the main piston b, when this is moved downward past its normal travel. Figs. 7 and 8 show a further arrangement in which the main piston b moves within a main cylinder a itself slidable within a pot-shaped bottom flange 11. If a pipe should be fractured so that the piston moves to the bottom of its travel sealing off the passages 16 from one another, the piston b will be locked to cylinder a by a lock bolt 20, Fig. 8, being engaged in a groove 22 in the head of the piston. Thereafter the piston b carries with it the cylinder a, so that fluid is compressed in the cylinder bores a<SP>11</SP> above auxiliary pistons u, which are fixed in the base of flange 11, and such fluid pressure is transmitted to the brake cylinders by pipes d.

Filed: 1951-07-18
Abstract: 702,231. Counting apparatus. WALKER & SON, Ltd., T. July 18, 1952 [July 18, 1951], No. 17034/51. Addition to 680,929. Class 106 (1). [Also in Groups IX and XXXVII] Relates to a control system for automatically terminating a repetitive operation of a part of apparatus such as machinery and for re-initiating it, so that a plurality of successive operational cycles are performed, as described in the parent Specification, additional means being provided to produce a signal for stopping further cyclical operation when the part has completed some predetermined total displacement or upon the completion of a predetermined number of operational cycles. The apparatus shown in the prior Specification has an additional control device 430 in the form of a cam-operated switch associated through a manually disengageable clutch with the worm 25 which is coupled to the machinery to be controlled. The worm 25 engages a worm wheel 401 keyed to a serrated clutch member 402 and freely journalled on a shaft 407. A clutch member 403 and pinion 405 are keyed to the shaft 407 which is movable against the force of a spring 404 to disengage the clutch members. A handle 406 is adapted to effect disengagement of the clutch and rotation of pinion 405. The switch 430 is operated by a pair of cams 421, 422, actuated through different gear trains from the pinion 405 so that one cam is driven at a multiple of the speed of the other, and the switch is actuated when the cams are in a predetermined relative position. A signal for stopping the machine is produced when the total displacement as measured by the worm 25, reaches an amount predetermined by the initial setting imparted to the cams 421, 422, and indicated by the pointers 423, 424. An alternative method of stopping the machinery at the end of a predetermined number of cycles comprises an electromagnetic counter and a solenoid which are energized at the end of each cycle of operation, Fig. 2 (not shown), a cam being advanced step-by-step by means of a ratchet actuated by the solenoid from an initial set position so that, at the completion of a predetermined number of cycles, the cam operates a switch for stopping the machinery. When it is desired to avoid the wastage of time involved by the resetting of the apparatus at the end of each cycle by means of the setting motor referred to in the prior Specification, the pinion 405 is driven by a non-reversing receiver motor which is linked with an electrical position transmitter driven by a suitable part of the machinery, Fig. 3 (not shown). Specification 934/99, [Class 40], is referred to.

Title: Improvements in or relating to the extraction of nickel from low grade ores
IPC: C22B23/02
Filed: 1952-07-07
Abstract: Nickel is extracted from low-grade ore in the form of a ferro-nickel alloy by intermixing molten metal, mainly comprising iron, with successive charges of molten ore so that the weight of the nickel in the metal is increased and then periodically withdrawing a part or the whole of the metal thus treated.  The successive charges of molten ore may be (a) added to a bath of steel or ferro-nickel alloy until the alloy attains the desired nickel content after which it is used or (b) mixed with a bath of high nickel-iron alloy, a quantity of alloy being drawn off for use after each charge.  The amount drawn off is approximately equal to the amount of nickel added per charge and the nickel content of the bath is prevented from exceeding a desirable maximum by adding iron to the bath.  This is done by direct addition and/or by reducing iron oxide present in, or added to, the ore by means of an added reducing agent, e.g. silicon, aluminium, ferro-silicon or silico aluminium.  The methods (a) and (b) above may be combined, e.g. by enriching a pure iron bath until it contains 40 per cent. Ni, drawing off half the metal and replacing it by iron, enriching the bath again and so on.  The metal and the ore may be intermixed by pouring one on to the other, in which case carbon=O.2-0.5 of the weight of the metal is preferably added to the metal and pouring takes place at such a rate that strong bubbling occurs, or by blowing gas-neutral, reducing or air-violently through the metal and ore.  If air is used, an element giving an exothermic reaction, e.g. carbon, manganese or silicon, may be added to the melt before each flow. The heat loss during the mixing of the ore and metal may be compensated for by heating the ore to a temperature slightly above that of the molten metal and/or reheating the metal between charges or by the use of exothermic agents, e.g. silicon or aluminium.
