Title: Improvements in and relating to sound reproducing apparatus
IPC: G11B7/00
Filed: 1930-08-11
Abstract: 360,898. Optical sound-reproducing apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, COCKE, K. J. R., 46, Dale Street, and EADE, S. R., 14, Laughton Road, Paddox Delivery, both in Rugby. Aug. 11, 1930, No. 24047. [Class 40 (ii).] Means for eliminating hum when the light source in optical sound-reproducing apparatus is fed with alternating current, comprises an auxiliary light - sensitive cell which is connected in circuit so that the current impulses therefrom are in opposition to those from the main cell. A beam of light from the source 1 is directed by an optical system 2 on to the film 3 and thence to a light-sensitive cell 4. Light from the source 1 also falls on an auxiliary light-sensitive cell 5 through an adjustable shutter 6. The cells 4, 5 are connected in opposition as shown in Fig. 2, in which 8, 9 are output impedances and 10 the leads to the amplifier. In an alternative arrangement, the auxiliary cell may receive light from a separate lamp the light from which fluctuates in phase with that of the sound-reproducing lamp. In a further modification, an optical system may be used to cause the light falling on the auxiliary cell to pass through the sound track as a wide beam, so that it is unaffected by the modulation of the sound track but is proportional to the mean density of the sound track, to make the hum-neutralizing means independent of the mean density of the sound track.

Abstract: 1,185,687. Supply systems for electrophotographic apparatus. RANK XEROX Ltd. 24 May, 1967 [2 June, 1966], No. 24121/67. Heading H2H. [Also in Division G2] An apparatus for fusing electroscopic items has a lamp 2 for emitting radiation in response to a signal from a trigger circuit, such as a relay or rectifier circuit. The lamp 2 has electrodes 4 and 6 to which a P.D. is applied to ionize gas in the lamp when a coil 8 generates a high field. A pulse forming circuit 12 for the lamp provides a pulse which reduces cathode sputtering and consequent blackening of the lamp envelope, caused by a voltage reversal across the electrodes 4 and 6. Inductors 30, 32 limit the peak current applied to the lamp, since as the current flow through the inductors decreases their magnetic fields decay, such that they supply current to the lamp. Diodes 22, 26 in parallel with capacitors 16, 18, by providing a shunt path for the respective capacitors, limit the voltage reversal across electrodes 4, 6.

Abstract: 207,505. Marks, E. C. R., (Assignee of Chadwick, L. S.). Nov. 23, 1922, [Convention date]. Addition to 206,545. Wick burners, annular, flame regulating in; materials for.- Improvements in or modifications of the wick burner described in the parent Specification comprise a lost motion device between the wick - operating spindle and the ratchet wheel controlling the wick stop mechanism to retard the descent of the flame spreader in order to offset inherent lost motion between the wick and its adjusting means; a roller bearing supporting the movable element which sustains the flame spreader and a brass or other non-rusting sleeve surrounding the spreader locking pin are also provided. The burner, which may have a wick elevator as described in Specification 206,112, is provided with a frame 31 to which the spreader 65 is latched in the manner described in Specification 213,293 by pivoted tumblers 68, the lower end of the frame being guided by a lug 33 on the rear branch 26 of a bracket 27 in which a wick-operating spindle 23 is journaled. Pivotally connected to the frame is a pawl-carrying member or stop plate 41 with a stop 42 to limit its angular movement with respect to the frame. The hub 46, Fig. 9, of a ratchet wheel 45, a tooth of which is engaged by a pawl 43 when by means of the wick the spreader, frame and stop plate have been raised a sufficient amount, is rotatably supported upon the neck of a head 48 at the end of the spindle, and the lost motion connection is provided by the engagement of a lug 52 of the ratchet wheel and a peripheral notch 51 in the head 48. This connection enables the wick to be lowered some distance before the spindle imparts movement to the ratchet wheel and so causes the spreader to descend. To counteract friction between the ratchet wheel hub and the neck 47 a brake 55 secured to the inner wick tube embraces the periphery of the wheel. Journaled in the head 36 of a portion 34 of the branch 26 is an antifriction roller 38 provided with a recess for a shouldered rivet 37, Fig. 6. When the stop plate 41 has been raised sufficiently to co-operate with the ratchet wheel its arcuate lower edge rides over the roller 38 which positions the flange 80 of the spreader in proper relation to the upper ends of the wick tubes. Adjustment of this position is effected by bending the neck 35. The spreader parts are preferably made of suitably rust-proofed steel and a pin 75, which forces the tumblers 68 into engagement with shoulders 69 of the spreader and constitutes lifting means for the spreader, is provided with a brass &c. sleeve.

IPC: C07C233/46
Filed: 1951-10-17
Abstract: The invention comprises thiols of the formula <FORM:0706724/IV (b)/1> and disulphides of the formula <FORM:0706724/IV (b)/2> (including optically active and racemic forms in each case), and the manufacture thereof by heating panthothenic acid or a lower (1-4C) alkyl, phenyl substituted lower alkyl or phenyl ester thereof with b -mercaptoethylamine or bis- (b -aminoethyl) disulphide.  The following alternative processes are also described: (a) reacting a di-O-acylated panthothenic acid halide with b -mercaptoethylamine or bis-(b -aminoethyl) disulphide, followed by mild hydrolysis to remove the O-acyl groups; (b) condensing pantolactone with the b -thioethylamide of b -alanine or with the corresponding disulphide; (c) reacting an N-pantothenyl-b -aminoethyl halide with an inorganic hydrosulphide or disulphide; (d) (for the thiols) condensing ethylene sulphide with pantothenyl amide.  The thiols may also be oxidized to the disulphides by means of air, iodine or hydrogen peroxide, whilst the disulphides may be reduced to the thiols by means of inorganic cyanides, thioglycollic acid, an alkali metal in liquid ammonia, or tin in a mineral acid.  The products are of pharmaceutical value.  In examples: (1) b -mercapto-ethylamine is heated with ethyl d-pantothenate in isopropanol or a mixture thereof with ethanol, or in ethanol in the presence of sodium ethoxide, or with methyl d-pantothenate in methanol or water in the presence of acetamide, or with d-pantothenic in ethanol, and the product is purified by chromatography; (2) bis-(b -aminoethyl) disulphide is heated with methyl d-pantothenate in water in the presence of acetamide, or with ethyl d-pantothenate in isopropyl alcohol, or with d-pantothenic acid in ethanol, or bis-(b -aminoethyl) disulphide dihydrochloride is heated with methyl d-pantothenic acid and a solution of sodium in methanol, the product in each case being purified by chromatography (in the last instance after filtering off precipitated sodium chloride); (3) b -mercaptoethylamine is refluxed with methyl dl-pantothenate in methanol in the presence of acetamide, or with ethyl dl-pantothenate in isopropyl alcohol, and the product is purified by chromatography.  The b -thioethylamide of b -alanine and the corresponding disulphide are obtainable by condensing ethyl carbobenzoxy-b -alanate or carbobenzoxy-b -alanyl chloride with b -mercaptoethylamine or bis-(b -aminoethyl) disulphide, or by treating N-(N1carbobenzoxy-b -alanyl)-2-aminoethanol with phosphorus pentasulphide, and in each case subsequently splitting off the carbobenzoxy group by the action of phosphonium iodide. The thiol may be oxidized to the disulphide by means of air, hydrogen peroxide or iodine before or after the carbobenzoxy group is split off. N-Pantothenyl-b -aminoethyl halides are obtainable by condensing a pantothenate ester with a b -aminoethyl halide.
