Patent GB-671939-A (GB)
Title: Diamidine salts and process for their manufacture
Filed: 1949-03-30
Abstract: The invention comprises diamidine salts of the general formula <FORM:0671939/IV (b)/1> (wherein each A represents an amidine salt grouping, that on the left being in the 5- or 6-position, and X represents S, O or NH), and their manufacture from the corresponding dinitriles by treating these with the oxonium halide of a heterocyclic compound containing "basic" oxygen in the ring, treating the resulting imino-ether hydrohalide with ammonia and converting the amidine formed to its salt with an acid, or by the Pinner method. The products are useful for therapeutic purposes, particularly as trypanocidal drugs.  In examples: (1) 2-(p-cyanophenyl)-6-cyanobenzthiazole is treated with dioxane "hydrochloride" and ethyl alcohol, the resulting imino-ether hydrochloride is treated with ammonia, and the product is crystallized from hydrochloric acid to give 2-(p-amidinophenyl)-6 - amidinobenzthiazole dihydrochloride dihydrate; (2) and (3) 2-(p-cyanophenyl)-5- and 6-cyanobenzoxazole are similarly treated; (4) 2-(p - cyanophenyl) - 5(6) - cyanobenzimidazole is treated with ethanol and dry hydrogen chloride in nitrobenzene and the resulting imino-ether hydrochloride is further converted as in (1).  Dinitriles of the general formula above, but in which each A represents a cyano group, are prepared as follows: (a) when X represents S, by condensing p-phenylenediamine monothiosulphuric acid with a p-acylaminobenzaldehyde (e.g. p - acetylaminobenzaldehyde), cyclizing the product (e.g. by refluxing with glacial acetic acid containing an alkali metal or ammonium acetate), converting the product by acid hydrolysis to the corresponding diamine and this to the dinitrile by the Sandmeyer reaction; or by condensing together o-aminothiophenols and aldehydes or acid chlorides, the reactants containing substituents (e.g. halogen atoms) subsequently replaced by nitrile groups (e.g. 5-bromo-2-aminothiophenol with p-bromobenzoyl chloride, with subsequent treatment with cuprous cyanide); (b) when X represents O or NH, by condensing together (with ring-closure by means of an oxidizing agent, e.g. lead tetracetate) o-aminophenols or o-phenylenediamines and benzaldehydes, acid chlorides or imino-ethers, the reactants being substituted by nitrile groups or substituents (e.g. NO2, NH2 or Br) subsequently replaced thereby (e.g. p  p-cyanobenzaldehyde with 4-cyano-2-aminophenol, or with 5-bromo-2-aminophenol with subsequent treatment with cuprous cyanide, or with 4-cyano-o-phenylenediamine).

Title: A reception system of high sensitivity for frequency or phase-modulated waves
IPC: H03D3/24
Filed: 1959-03-13
Abstract: 911,495. Frequency and phase modulation receivers; frequency detection circuits. NIPPON ELECTRIC CO. Ltd. March 13, 1959 [March 20, 1958], No. 8809/59. Class 40 (5 ). In a frequency or phase modulation receiver with improved signal/noise ratio an oscillator 6 has its phase retroactively stabilized to be equal to the mean value of the phase of the incoming I.F. and demodulates the I.F. by applying the vector sum of it and quadrature phase oscillations of larger amplitude from the oscillator 6 to a phase discriminator 5, whose output amplified at 7 passes through a low-pass filter 12 to control the oscillator 6 to the I.F. mean phase. Moreover, high-frequency components of the output from 7 are passed through a high-pass filter 13 to frequency modulate the receiver's initial local oscillator 3, to reduce the I.F. frequency swing and phase difference at the phase detector 5 within a limit of Œ 1 radian. The output of I.F. amplifier 4 may also be passed through a 90 degrees phase shifter 9 to make it of approximately the same or opposite phase as an input from oscillator 6 also applied with it to a detector 10, its output of amplitude proportional to the output of amplifier 4, being then used for automatic gain control of the amplifier 4, to further improve the signal/noise ratio. In a modification the output of amplifier 7 is directly applied to the oscillator 6 so that it follows up the incoming frequency swing but still retains an average phase differing from the average phase of the output of amplifier 4 by 90 degrees. Specification 555,618 is referred to.

Title: Improvements in or relating to two-stroke internal-combustion engines
IPC: F02B3/06
Filed: 1950-04-13
Abstract: 680,477. Crank-chambers; cylinders; spraycarburetters. LOHMANN WERKE AKT.-GES. April 13, 1950 [April 25, 1949], No. 9080/50. Classes 7 (ii) and 7 (iii). In a two-stroke compression-ignition internalcombustion engine wherein fuel and air are admitted to the crankcase 6, Fig. 1, and subjected to the action of the parts moving therein to diffuse and mix the fuel with the air, it is arranged that as the mixture is transferred to the combustion chamber it contacts with the outer surface of the piston 2 so as to effect cooling thereof and to become preheated thereby and the compression ratio is adjustable for starting purposes and during operation of the engine under different load conditions. The cylinder liner 9, which has piston-controlled inlet and exhaust ports 11 and 12 respectively that cooperate with corresponding ports 7 and 8 in the cylinder 1 is also provided with curved transfer recesses 13, Fig. 5, for establishing communication between the crankcase 6, Fig. 1, and the combustion space under the control of the piston 2. The liner 9, which has a cam plate 14, Fig. 5, at its upper end comprising two equal cams 15 mutually displaced by 180 degrees, is forced by the pressure in the combustion space into contact with an adjusting part 16, Fig. 7, the latter being rotatable and embodying two stops 17, each cooperating with a cam 15, which stops can be angularly adjusted through a range of about 120 degrees upon turning the part 16 by means of a Bowden cable (not shown), for example, in order to vary the compression ratio for different conditions of engine operation. The air and fuel are warmed by passing them through separate passages 20, 21 Fig. 9, in the. cylinder walls before they enter the inlet port; the mixture is further heated by contact with the piston during traversal of the recesses 13, whilst mixing of the fuel and air is enhanced-by contact with the crankcase and the moving parts therein, which latter may have roughened surfaces to further increase this effect. Between the passages 20, 21 and the inlet port 7 there is arranged an atomizer comprising a spring- loaded piston 24 axially movable by a rod 25 through a Bowden cable, for example. The piston has a recess 27, to control the quantity of air flowing from, passage 20 to port 7 via an air intake conduit 28, and a spindle 23 protruding into a nozzle 22 to a degree dependant upon the position of the piston 24, the nozzle communicating with the fuel passage 21. The cylinder 29 of piston 24 has a pipe 30 leading from its front end to the air conduit 28. Fine screens or baffles 31 may be placed between the pipe 30 and the cylinder. Both the atomizer and the compression-ratio control have positions for no-load, starting, partial and full-load conditions.
