Title: Improvements in or relating to apparatus for measuring and/or indicating small quantities
IPC: G01B7/34
Filed: 1940-02-01
Abstract: 539,274. Electric indicating systems. KAPELLA, Ltd., REASON, R. E., and GARROD, R. I. Feb. 1, 1940, No. 1981. Drawings to Specification. [Class 40 (i)] Modifications of the arrangements described in Specification 539,271 for measuring and indicating surface roughness are described, and their application is extended to the measurement of pressures, small mechanical movements and ordinary gauging. The modifications relate to alternative means for obtaining full scale deflection of the instruments for a small range of movement of the controlling stylus which by means of a pick-up which modulates or controls the amplitude of the output of a source of A.C. For this purpose, the percentage modulation of the A.C. is controlled by combining with the output of the pick-up an opposing A.C. voltage of adjustable amplitude. The opposing A.C. voltage may be derived from a similar pick-up in which the stylus is replaced by a manually adjusted armature, or it may be derived directly from the source and phase opposition of the two voltages or may be obtained by phase shifting networks. These arrangements may be used in conjunction with the "backing off" arrangement described in the above-mentioned Specification. The Provisional Specification describes also a mixer valve for combining the modulated and unmodulated A.C. in varying proportions and a cathode ray shadow indicator to indicate the proportions. Specifications 539,272 and 539,273 also are referred to.

Filed: 1943-04-23
Abstract: 565,748. Valves. BOORER, A. April 23, 1943, No. 1998. [Class 7 (vi)] In an engine having a valve chamber 10 containing inlet and exhaust valves 16, 17 which at the appropriate times are isolated from the engine cylinder by a master valve 11, the master valve 11 and the port it controls are arranged in a cavity 12 in the cylinder head and the head of the master valve, when open, approaches closely to the position of the crown of the piston at top dead-centre, the cavity constituting substantially the whole of the combustion space when the piston 15 is at top dead-centre. The cross-sectional area of the cavity transverse to the axis of the cylinder is kept to a minimum to make it comparable with the depth of the cavity which is determined by the lift of the valve necessary to ensure a minimum resistance to flow past the valve, the valve opening in the direction of the cylinder axis. In operation, the master valve 11 opens at the point in the normal cycle usual for the opening of the exhaust valve, but the exhaust valve 17 is by this time fully open and the master valve closes at the point in the cycle usual for the closing of the inlet valve, but the inlet valve 16 remains open for some time after this. The exhaust valve and the master valve are actuated by a common cam 18.

Title: Improved treatment of lead chloride or basic chloride to convert it into other lead compounds, and application thereof to the winning of lead from ores, residues and the like
IPC: C01G21/00
Filed: 1924-01-30
Abstract: Ammonium chloride is produced by converting lead chloride into carbonate by means of ammonia and carbon dioxide.  The lead chloride or a double chloride of lead such as lead ammonium chloride is suspended in a solution of ammonia and carbon dioxide is passed in. The first part of the reaction may be effected at about 30 DEG  C. and the later part at a higher temperature such as 40-50 DEG  C. Specification 3082/77 is referred to.ALSO:Lead chloride is converted into a carbonate by suspending in aqueous ammonia and passing in carbon dioxide.  The lead chloride may be obtained by known methods from ores, concentrates &c. and is preferably used in finely divided form obtained for instance by grinding the crystals or by precipitation of a solution of lead chloride in a chloride solution by dilution with a large quantity of water; or a double salt such as lead-ammonium chloride may be used as such.  The lead chloride may also be obtained by the treatment of metallic lead from residues with acid brine, hydrochloric acid, ferric chloride, or the like.  The ammonium chloride in the mother-liquor may be crystallized by cooling and may be employed for the extraction of lead chloride from ores or may be heated with lime to recover the ammonia and obtain calcium chloride solution for treatment of lead ore.  The conversion of the lead chloride into carbonate may be effected at about 30 DEG  C. during the first part of the carbonation, and, when less ammonia remains free, at a higher temperature such as 40-50 DEG  C.  The carbonation may be effected on the counter-current principle.  The mother-liquor containing ammonium chloride, ammonia, and carbon dioxide may be divided into two portions, one, called the nucleus solution, being made up to its original quantity with water, ammonia, and lead chloride for the next operation, while the other is treated to recover its constituents.  In an example, zinc lead sulphide ores are roasted to sulphate the metals, the zinc is leached out as with a solution of sulphuric acid, and the residue, containing lead and silver sulphates, is treated with a hot chloride solution containing a little acid to extract the lead and silver.  The silver is recovered in known manner, and the lead chloride is separated out by cooling and treated as above described.  Specification 3082/77 is referred to.  The Provisional Specification refers to Specification 210,463, [Class 2 (iii), Dyes &c.].
