Filed: 1941-09-10
Abstract: 654,226. Radiolocation. STEVENS, A. H. (Leland Stanford Junior University, Board of Trustees of). Sept. 10, 1941, No. 3132/48. Divided out of 654,221. Drawings to Specification. [Class 40 (vii)] In a radiolocation system, the transmitter and receiver are alternately rendered operative for equal short periods by a high-frequency oscillator the frequency of which is varied through a range of about 1 per cent to ensure that reflections from objects at all distances will be received at a time when the receiver is operative. A further oscillator of lower frequency also interrupts or modulates the transmitter and receiver and distance is measured by varying its frequency until the first minimum of reception is reached. The received signals are caused to give a beat-note the frequency of which determines the relative velocity of a moving object. The invention is described with reference to a system identical with that described in Specification 654,221. Specifications 523,712, 531,251, 654,222 and 654,223 also are referred to.

Title: Improvements in or relating to the preparation of amidine salts
Filed: 1944-02-23
Abstract: Amidine salts are obtained by the reaction of an iminothio-ether base with a salt of ammonium or of a primary or secondary amine.  In particular, from the appropriate di-iminothioether bases are obtained salts of aromatic diamidines of the general formula Am.B.X.B.Am, wherein Am represents the amidine or N-substituted amidine group, B represents an aromatic residue and X represents: (a) a direct linkage, or (b) an alkane chain (CH2)n, wherein n is an integer from 1 to 12 and in which one or more of the -CH2- groups may be replaced by an oxygen or sulphur atom or by an -NH-group, or (c) A-CR1=CR2- group, wherein R1 and R2 represent hydrogen atoms or alkyl, aralkyl or aryl groups and may be the same or different. Advantageously, the treatment is at an elevated temperature, but below that at which any substantial quantity of ammonia is evolved, and the proportions of the reactants are adjusted so that when the ammonium or amine salt is in aqueous solution and the imino thio-ether is in alcoholic solution both reactants remain in solution when such solutions are mixed at 50-80 DEG  C.  In examples: (1) a -e -diphenoxy pentane-4 : 41-bis-(carbonim inothiobenzyl-ether) is heated with ammonium chloride in aqueous ethyl alcohol at 60-70 DEG  C. for 26 hours, the solution is decanted into acetone and the precipitated 4 : 41 - diamidino - a ,e  - diphenoxy-pentane dihydrochloride is recrystallised from dilute hydrochloric acid; (2) a - - diphenoxy-propane-4 : 41-bis-(carboniminothiobenzyl-ether) in alcoholic solution is mixed with an aqueous solution of ammonium chloride and the mixture is heated at 60-70 DEG  C. for 48 hours; the filtered reaction solution is poured into acetone and the a -g -diphenoxy-propane-4 : 41-bis-(carbonamidine) dihydrochloride is precipitated; (3) trans-stilbene-4 : 41-bis-(carboniminothiobenzyl-ether) in alcoholic solution is mixed with an aqueous solution of ammonium b -hydroxyethanesulphonate, the mixture is heated at 40-50 DEG  C. for 30 hours and thereafter at 70 DEG  C. for 4 hours to obtain trans-stilbene-4 : 41-bis-(carbonamidine)-di-b -hydroxyethanesulphonate; (4) diphenyl ether - 4 : 41 - bis - carbon - iminothiobenzyl - ether) in alcoholic solution is mixed with an aqueous solution of ammonium b -hydroxyethane sulphonate and the mixture is heated at 70 DEG  C. to obtain 4 : 41-bis - (carbonamidine) - di - b  - hydroxyethanesulphonate, and the solution may be treated with caustic soda to obtain the free base.  Specification 549,639 also is referred to.  Di-benzylthio-imino ethers used in the examples are obtained by the reaction of the corresponding nitriles with benzyl mercaptan.

Title: Improvements in or relating to pulverising mills
IPC: B02C15/08
Filed: 1925-02-11
Abstract: 230,427. Fuller-Lehigh Co., (Assignees of Breerwood, C. H.). March 7, 1924, [Convention date]. Ball-and-ring mills. -In a ball-and ring mill, a single means or device is provided for each ball which performs the dual function of propelling the ball and lifting the material passed over by the ball and depositing part of it in front of the following ball. As shown, Fig. 1, the devices or plough-pushers 20 are carried by the radial arms of a yoke 11 similar to that described in Specification 230,438. Downwardlyextending arms 18, Fig. 2, on a ring 17 joining the outer ends of the arms of the yoke 11 have at their lower ends square shanks which enter vertical sockets 24, Figs. 4 and 5, in the central hubs 21 of the plough-pushers 20, a locking-pin passing through each shank and through a transverse aperture 25 in the plough-pusher. A forwards-extending projection 26 on the ploughpusher is curved on its front surface to provide a seat for the grinding-ball 19, and extending across the lower surface of the plough-pusher is a fin or rail 28 which curves inwardly near the outer edge as at 29 where it joins a lateral fin 30 extending to the rear of the outer face of the body of the plough-pusher. The two fins 28, 30 merge into one another so as to form a smooth surface, and the fin 30 extends into the concave portion of the grinding-ring 13. As the yoke 11 rotates, the fin 28 dislodges the material which is likely to be packed in the raceway and the loose material is thrown outwardly, passing under the rounded leading-edge 26<1> of the extension 26. The material then passes over the fin 30 and is elevated so that part of it enters the zone of action of the lifting-blades 31 carried by the yoke 11, the coarser particles being deposited in the path of the following ball. The upwardly and rearwardly inclined blades 31 may be bolted to or be integral with the arms 18 and ring 17. The fan-blades 32 carried by brackets 33 on the yoke float the material against the screen 34 in the upper part of the mill, and the finer particles pass through the screen and are delivered through the spout 37 by a rotating platform 38. The plough-pushers may be fitted to mills having yokes with radial arms lying in an horizontal plane. In the arrangement shown in Fig. 7, the plough-pusher has an horizontal socket 39 and a vertical aperture 40 for the locking-pin.
