Title: Bis-(n-disubstituted-aminoalkyl)-sulphide di-alkyl halides and process for the manufacture thereof
Inventor: MORRISON ALEXANDER LANG
IPC: C07D295/02
Filed: 1950-12-08
Abstract: The invention comprises compounds of formula <FORM:0698506/IV (b)/1> where R1 and R2 are alkyl groups which together with the N atom to which they are attached may be a piperidino or morpholino radicle, -C3 .. 7- is an alkylene group (other than an alkyl-substituted methylene group) of 3-7 C atoms and X- is a chloride, bromide, iodide or methylsulphite ion.  They may be made by condensing the appropriate N-disubstituted-aminoalkyl halide and N-disubstituted-aminoalkyl thiol in the presence of an alkaline condensing agent and reacting the product with the required alkyl halide or dimethyl sulphate. Alternatively quaternary ammonium salts of the above halides and thiols may be condensed.  The former method is adopted when the halide used does not internally quaternize at a rate faster than that of the condensation.  The thia-alkanes are also made by treating the appropriate N-disubstituted-aminoalkyl halide, or its quaternary salt, with an alkali-metal, sulphide.  The required thiol may be made in situ by treating an excess of the appropriate halide with an alkali-metal hydrogen sulphide.  The thiol then reacts with excess halide, the alkali-metal hydrogen sulphide serving as a condensation agent.  Sodium methylate and ethylate are specified condensation agents.  Condensation with free bases are preferably effected in inert atmospheres.  The compounds inhibit neuro - hormonal transmission.  In examples: (1) 4-thia-heptane-1,7-bis-(triethylammonium iodide) is made by treating chloropropyl triethylammonium iodide with sodium sulphide in aqueous alcohol; (2) 5-thia-nonane 1,9-bis-(trimethyl-ammonium bromide) is made by reacting chlorbutyl-trimethyl ammonium bromide with aqueous alcoholic sodium sulphide; (3) 2,4-dimethyl-3-thia-pentane-1,5-bis-(trimethylammonium iodide) is made by reacting 2 - chloro - 1 - dimethylamino - propane with sodium hydrogen sulphide under nitrogen and the product with methyl iodide in benzene and in (4) 3-thia-pentane-1,5-bis-(trimethyl-ammonium iodide) is made by condensing 2-dimethylamino-ethane-thiol with 2-chloroethyldimethylamine in the presence of sodium ethylate and quaternizing the product with methyl iodide.

Abstract: 642,097. Pulse modulation; multiplex signalling. SADIR-CARPENTIER. Oct. 10, 1946, No. 30320. Convention date, Oct. 25, 1945. [Class 40 (v)] In an impulse modulation communication transmitter comprising a source 1 of periodically recurring impulses, a linearizing counter reaction loop 5, 6, 7 is associated with a modulator 3, the output current of which is fed through an impulse frequency dividing circuit. Modulation is therefore effected on a train of impulses, the repetition frequency of which is a whole multiple of the output pulse frequency. Distortion is reduced by the loop 5, 6, 7 which comprises a demodulator, a low-pass filter and attenuator or dephaser, the low-pass filter being arranged to cut off at a relatively high value as determined by the frequency of the source 1. When used for a multiplex system, Fig. 2 (not shown), several channels are fed in parallel from source 1, each channel being modulated separately and the frequency divider giving modulated outputs of lower repetition frequency. These outputs are then combined in a mixer and transmitted as a pulse train which is representative of all the channel signals.

Title: Improvements relating to photographic sound records and methods of producing same
IPC: G11B7/00
Filed: 1936-11-11
Abstract: 477,724. Optical sound recording. BRITISH ACOUSTIC FILMS, Ltd., POULSEN, A., KOLB, O. K., PRATT, A. S., and BOSTON, D. W. Nov. 11, 1936, No. 30824. [Class 40 (ii)] In " noiseless " film sound-recording, in which a portion of a sound modulated electric current is rectified and applied either directly or through known amplifying and smoothing circuits to produce an increase of the mean width or mean transparency of the sound track, corresponding to an increase of the amplitude of the sound recorded, disturbances of the mean width or mean transparency of the sound track due to stray currents of high audible frequency in the microphone, valves, &c. are avoided by providing a filter having a cut-off in the higher audible frequencies in that part of the circuit which produces variation of the mean width or mean transparency of the sound track. The sound-recording system may comprise a microphone 1 followed by an amplifier 2 whose output is applied over the lines 3 and through the transformer 4 to the recording device 5. The amplifier output is tapped by lines 6 connected to the grid and cathode of an amplifier valve 7 biassed by a resistance 8 and condenser 9 in the cathode circuit. The anode of valve 7 is fed through the resistance 10 and its output is taken through the blocking condenser 11 to the filter circuit consisting of inductances 12, 13, condensers 14-16 and resistance 26 connected as shown, and thereafter applied to the grid of valve 17 which is biassed by a resistance 18 and condenser 19. The output of valve 17 is applied to the primary of a transformer 20, a condenser 27 being inserted to give a sharper cut-off than would be given by the filter circuit alone. The secondary winding of the transformer 20 is connected to the two anodes of a double diode valve 21, the output of which is passed through a filter consisting of a resistance 22 and condensers 23, 24 and then is applied, through a further valve 29 to the recording device 5, thus supplying the necessary bias current which will be zero when there is no sound input and will increase when the sound input causes an increase of the rectified current. The valve 29 acts as a direct current amplifier. A condenser 25 is provided to prevent the D.C. output from the rectifier from passing also through the secondary winding of the transformer 4. The cut-off is conveniently made at 7000 or 8000 cycles per second.

Filed: 1938-01-28
Abstract: 493,644. Photo - electric control of film-feeding mechanism. SIFICO AKT.- GES., and WAHL, K. Jan. 28, 1938, No. 30982 /36. [Class 40 (iii)] [Also in Group XX] In copying from a perforated negative film on to an unperforated positive film, the perforations of the negative film are marked on the positive film and subsequently effected by a punch controlled by photo-electric cells, the light action on which is regulated by the perforation images. The perforations are recorded on the positive film either photographically, by pressure, or by colour spraying. The positive film 1 with the markings thereon, is passed over the conducting surface of the perforating machine 2 past a slit 3. A lamp 4 throws an image of the markings on to a blind 6 in front of the two photo-electric cells 7, 8. When a marking is displaced in position, its shadow falls on the cells 7, 8 and a relay 9 acts on a motor 10 to regulate the position of a claw 13. The claw stroke is unaltered but its position is varied thus producing a variation in the speed of the film and controlling the separation of the punched perforation.
