Filed: 1949-02-25
Abstract: 669,902. Ignition testing apparatus. FARNSWORTH, D. G. Feb. 24, 1950 (Feb. 25, 1949], No. 5222/49. Class 7(iv) In apparatus for use in determining the position of a piston in an internal-combustion engine comprising a pneumatic pressure-responsive device, such as a piston and cylinder 46, 35 adapted to be connected to the combustion chamber of an engine cylinder and to be subjected to pressure variations of the air or gases therein resulting from the slow reciprocation of the associated engine piston, there is provided means, such as a lamp 56, associated with the pressure-responsive device for indicating electrically when the engine piston has reached a predetermined point in its stroke. The sparking plug of a given engine cylinder is replaced by a union on one end of a flexible hose 40, the other end of which is connected to the cylinder 35 ; the plug, lead is connected to the adjustable electrode 80 of. a spark gap and the associated fixed electrode is earthed. The piston 46 in cylinder 35 has on its outer end a metal disc 50 which in the lower position of the piston bridges two contacts 52, 60 so that actuation of a switch 55 will cause the lamp 56 to be illuminated. The piston 46 is loaded by a spring 62 the compression of which is adjustable by rotation of a shaft 65, one part having a right- and the other part a left-hand thread, in order to adjust the distance between two roller-ended arms 67, 68, the rollers engaging a conical member 61 having a reduced portion 64 located in the end turns of the spring 62. The threaded shaft is rotated from a knob 72 through a disc 74 in frictional driving relationship with a dial 75 on the shaft, the dial 75 being graduated to enable any desired position of the engine piston to be indicated by pre-setting of the dial and hence compression of the spring- The engine is turned slowly on the compression stroke so that the piston 46 is lifted and breaks the circuit through disc 50 to the lamp 56 ; when the piston reaches a predetermined position the compression of the spring 62 and the setting of a bleeder valve 48 are such as to enable the piston 46 to fall, thus again illuminating the lamp 56 and thereby enabling the distributer to be adjusted to produce an ignition spark at this point, the spark being seen at the spark gap. The piston may be replaced by a diaphragm.

Title: An improved method of removing mono alkaline earth phosphates from mono alkali phosphate solutions
IPC: C05B7/00
Filed: 1928-02-21
Abstract: 298,436. Benckiser, T., Reimann, A., and Reimann, A., (trading as Benckiser, J. A., [Firm of]), and Draisbach, F. Feb. 21, 1928. Alkali and alkaline-earth phosphates.-In the method of producing alkali phosphates by treating crude phosphates with sulphuric acid and neutralizing the solution by means of sodium carbonate or the like, the resulting mono-phosphate solution contains more or less monophosphates of the alkaline earths. These may be converted into di-alkaline earth phosphates by adding a calculated excess quantity of dialkali phosphate and heating the solution in an autoclave at a high pressure, e.g. 5-15 atmospheres up to temperatures between 150‹ and 200‹ C. The di-alkaline earth phosphates are precipitated in a readily-filterable form, and are easily separated, leaving a solution of monoalkali phosphate.

Abstract: 696,510. Continuous - casting machines. METALLURGICAL PRODUCTS, Ltd. March 17, 1952 [March 7, 1951], No. 5487/51. Class 83 (i). A continuous-casting machine comprises an elongated mould cavity 11 formed by two mould members 10, 12, means 17 for feeding molten metal into one end of the cavity, means for displacing the members 10, 12 relatively in a direction longitudinally of the mould, and means 26, Fig. 2, in one of the members 10, 12 for venting the cavity 11 to the atmosphere, the vent extending longitudinally of the cavity for a length over which the surface layers of the cast billet 30 are sufficiently liquid as to escape between the members 10, 12 if the mould were not vented and the members 10, 12 forced apart by gases in the cavity. Metal is cast from a box 17 into the cavity 11 where it engages ribs or threads formed in the end 21 of a draw-block 20 which is keyed at 22 to an annular rib 14 on the circular base 10. The latter is rotated relatively to the upper part of the mould to produce a continuous billet which frictionally engages the base so that the block 20 may be removed when it has passed out of the cavity. Sprays 31 of water, or air-atomized water suspended in air or a mixture of air and steam &c., may be provided to cool the billet before it is stripped from the base 10 by a roller 32 on a hydraulic ram 33 and further rollers 34, Fig. 1. The upper member of the mould, which may provide a cavity as illustrated or one of semicircular or of inverted " V " form, is constructed in a number of sections 24 connected at 2 and each having two parts 13 with passages 29 for cooling water. Opposed parts 13 are clamped together at 27 such as to provide the vent 26 between them and are suspended from links 6 so that a liquid-tight joint is formed between the inclined walls 15 of the members 13 and the rib 14 if such is provided. The vent 26 may extend from the box 17 to the end 19 of the mould or start after the first section 25, which may be undivided. If the vent, which may be filled with sand, Fig. 4 (not shown), or oil-sand, does not extend to the end 19 of the mould, a slot is provided in the rest of the mould to accommodate the small fin caused by the vent. In various modifications (not shown), the base 10 may be constructed as an annular disc supported on spokes, the feed gate 13 of the box 17 may be replaced by a nozzle extending into the end 16 of the cavity 11, and the draw block 20 may be replaced by an equivalent means. Specifications 323,315, [Class 83 (i)], and 465,595 are referred to. The Provisional Specification states also that the rib 14 may be of rectangular crosssection and refers to the disadvantages involved in forming the vent by a series of spaced holes. Specification 696,509 also is referred to.

Filed: 1924-03-04
Abstract: 235,272. Hutchins, T. W. S. March 4, 1924. Addition to 197,066. Metals, depositing; cells; diaphragms; electrodes, moving; electrolytes, circulating and regenerating.-The invention of the parent Specification is modified by the provision of means whereby the electrolyte passes from the cell to the recuperating plant and returns therefrom without being broken up and subsequently aerated and acidified. Electrolyte enters the cathode compartment r, Fig. 2, of a cell for the deposition of metals by a pipe u and passes over the top of the diaphragm v into the anode chamber s, which is filled with scrap and/or ore of metal to be deposited. The spent electrolyte leaves by a pipe 4 and passes along a trough 5 to a vessel 6, Fig. 1, whence it leaves by a valve 7 operated by a float when the vessel is nearly full. The electrolyte passes from the vessel 6 to a vessel h, whence it is pumped to recuperators d, e.. It then passes by a valve, m to a filter c from which it returns through a valve n to the cells. The recuperator e is connected to the vessel h by a bye-pass containing an adjustably loaded valve l which only opens when the head in the veot-pipe i rises. The recuperator e is also connected to the return pipe to the cells by a bye-pass containing a valve o. By closing the valves m, n and opening the valve o the flow through the filter may be reversed to remove deposits which are discharged through a sludgecock p. The cathode q, Fig. 2, has a collar w at its upper end resting on a pulley x rotated by a rope or other means. The weight of the cathode is sufficient to ensure its rotation with the pulley. Electrical connection is made by brushes carried by a ring z secured by a hinged plate 2, the free end of which rests on a stop 3. By raising the plate 2 the cathode may be withdrawn. The diaphragm v is only slightly porous. On account of the direction of flow there is no tendency for disintegrated anode particles to enter the cathode chamber. The cell has a lead liner t' serving as anode connection.
