Title: Improvements in and relating to lead sodium alloy
IPC: C22C11/02
Filed: 1935-11-18
Abstract: Lead-monosodium alloy for use in the preparation of organic lead compounds such as tetra-ethyl lead is made in the form of small uniform granules having a mean diameter of about \ba1/32\be to about \ba1/8\be inch and being substantially free from alloy in the form of dust.  The term uniform means that in any batch of granules the smallest particle is not less than about half the size of the largest.  The granules may be in the form of crystals of octahedral structure having rounded edges and well-polished surfaces so that they resemble rice grains.  The granules may be prepared by crushing and sieving but are preferably made by cooling a lead-monosodium melt with continuous stirring and in the absence of moisture or oxygen, e.g. in an atmosphere of nitrogen, hydrogen, or helium, to a temperature below that at which the particles of the alloy tend to adhere to each other, e.g. to about 275 DEG  C.  To produce grains with rounded edges the melt is stirred fairly rapidly, for example at a rate of about 15 revolutions per minute.  To prepare organic lead components the granules are caused to react in the usual way with organic halides, the uniformity of the granules resulting in an increased yield.ALSO:Lead-monosodium alloy, particularly for use in the preparation of organic lead compounds such as tetra-ethyl lead, is made in the form of small uniform granules having a mean diameter of about 1/32 to about 1/8 inch and being substantially free from alloy in the form of dust.

Title: Improvement in the manufacture of acetone from acetylation liquors
IPC: C07C49/08
Filed: 1928-11-02
Abstract: 300,548. Wacker Ges. f³r Elektrochemische Industrie Ges., Dr. A. Nov. 14, 1927, [Convention date]. Grant of Patent refused. Acetone.-The liquors produced in the precipitation of acetylated polysaccharides such as cellulose or starch acetates are vaporized and the vapour without any purification passed over a catalyst adapted to produce acetone, such as a catalyst containing cerium carbonate, at 300- 500‹ C. If foaming occurs in the evaporation a foam-separator may be employed or spent liquor may be continuously withdrawn from the still, or both these measures may be employed. Liquors mentioned in the examples are those obtained in the acetylation of starch by the aid of zinc chloride, the acetylation of cellulose by the aid of sulphuric acid (in which case any free sulphuric acid may be neutralized with sodium acetate) and similar processes in which acetyl chloride is used as acetylating agent or sulphuryl chloride as catalyst. The catalyst for the acetoneforming reaction is made by suspending cerium carbonate in weak gelatine solution and impregnating pumice (of which 100 pieces weight 21.5 grams) with the suspension, the material being then dried and heated to 470-480‹ C. before admitting the vapour to be treated.

Title: Electric circuit arrangements including frequency dividing circuits
IPC: H03B21/02
Filed: 1948-12-21
Abstract: 663,921. Pulse frequency dividing circuits; pulse modulation circuits. WESTERN ELECTRIC CO., Inc. Dec. 21, 1948 [Dec. 24, 1947], No. 32952/48. Classes 40 (v) and 40 (vi). In a frequency-dividing circuit in which two dividers are connected in cascade, pulses from a source are applied to both dividers and an interconnection between the two ensures that the output voltages of the two stages have a pre-determined phase relationship. Figs. 1 and 2 show the application of such a divider circuit in a 7-digit 12-channel pulse code multiplex communication system in which a 12-stage ring circuit 14 derives the channel frequency from the pulse group frequency and a further 2 to 1 divider 26 derives a routing frequency which is one half the pulse group frequency for segregating the odd and even channels. Pulses from a master pulse source 10 are shaped in unit 11, divided in frequency by the 7 to 1 divider 12 and shaped in unit 13. The pulses from shaper 13 are applied to the ring circuit distributer 14 which comprises twelve ring-connected 2 to 1 dividers 14, Fig. 2, so that as conduction steps round the ring in known manner pulses appear at the outputs O1 02 ... 012, Fig. 2, sequentially. Each output pulse activates an associated sampler M1, M2 ... M12, Fig. 1, which connect the incoming message lines L1, L2 ... L12 sequentially to the common lead 15. The signals on line 15 are applied to two coder control devices 22, 23 which control the " even " and " odd " coders 20, 21 which may be of the type described in Specification 637,820 to give a 7-digit code. Messages are directed alternately to the " even " and " odd " outgoing lines 32, 33, respectively, under the control of divider 26, Fig. 1, which is itself controlled by output pulses from shaper 13. The ring divider 14 and the 2 to 1 divider 26 are interconnected as shown in Fig. 2 to produce a pre-determined phase relationship between their outputs, thus ensuring that signals are correctly routed to either the " even " or " odd " lines 32, 33. As shown in Fig. 2, pulses from shaper 13 are applied symmetrically to the 2 to 1 divider stage 40, 41 via the control valves 49, 48 and the output pulses are taken from the grid resistors 44, 45 of the divider stages to units 22 and 23, Fig: 1, via buffer stages 50, 51. The ring circuit distributer 14 has an output taken from the first stage and connected asymmetrically to the anode circuit of valve 40 via the differentiating circuit 60, 61 and the buffer stage 56. If the phase relationship between the output pulses of divider 40, 41 and ring circuit 14 is incorrect the correct relationship is restored by the triggering action of the differentiated output pulse of ring circuit 14 on the 2 to 1 divider 40, 41, Figs. 3, 4 (not shown).
