Abstract: 533,134. Punching-machines. WARNER BROS. PICTURES, Inc. Oct. 12, 1939, No. 27761. Convention date, Oct. 24, 1938. [Class 31 (ii)] [Also in Group XXXVIII] A film has a blackened sound track which is punched at regular intervals so that when run synchronously with an existing picture film it indicates the correct "tempo" for a musical accompaniment. The punching machine comprises reels 17, Fig. 1, which carry the existing picture film 53 and the film 51 to be punched. These films are advanced side by side for comparison during the punching operation by means of sprockets on an axle 52 intermittently rotated by pawl mechanism from a rack 28 which is oscillated'longitudinally by a crank 24 rotated through chain and gearing by motor 42. The extent of advancement of the films is varied by moving the crank pin 80 along the crank arm 24. On its inactive stroke the rack 28, moving rightward in Fig. 2, actuates a single-acting lever 91 which by a bell-crank 95 depresses a punch 96 to perforate the film 51. Means to stop the apparatus at any particular point comprises a screw clamp 131, Fig. 1, which grips the rack 28 and simultaneously, through rods 135, 138, causes the driving motor 42 to be declutched. A footage indicator is driven from the sprocket axle 52 and a perforation counter is operated from the punching mechanism.

Title: Improvements in or relating to hydraulic shock absorbers
IPC: F16F9/42
Filed: 1954-09-28
Abstract: 758,798. Hydraulic shock absorbers. DAHL. G. H. Sept. 28, 1954 [Sept. 30, 1953; Sept. 17, 1954], No. 27999/54. Class 108 (3). The invention relates to hydraulic shock absorbers of the type comprising a piston 10 having passages 13, 14, closed by valves 15, 16, operating for opposite respective directions of piston displacement, and a cylinder 20, surrounded by a reservoir 1, communicating with the upper and lower portions of the cylinder. According to the invention, an annular part 8 which closes the cylinder 20 carries a cylindrical skirt 22, and has at least one calibrated aperture 23 forming a communication between the cylinder 20 and the annular space between the reservoir 1 and the skirt 22. In Fig. 1, the skirt 22 extends over the whole length of the reservoir. There are two calibrated apertures 23, 24 to provide the flow path between the cylinder 20 and the reservoir 1. The cylinder 20 and reservoir 1 are connected at their lower ends by a valve assembly 21 which includes a calibrated compression valve 26 and a lightly-loaded rebound valve 28. The valve 26 is more heavily loaded than the valve 16 on the piston. The easing of the reservoir 1 is provided with metal cooling fins 25. In operation, on compression, liquid flows upwardly through the piston passages 14 and is displaced out of the cylinder via the apertures 24, 23, into the reservoir 1. The skirt 22 maintains the liquid in the proximity of the casing which is cooled by the fins 25. On harder compression, liquid is also displaced through the valve 26. On rebound, liquid is forced by the piston through the apertures 24, 23, and on more severe rebound the valve 15 on the piston is lifted. The cylinder is replenished via the valve 28. In Fig. 7, the skirt 32 is shorter, and is outwardly turned at its lower end to deflect liquid on to the cylinder wall. The apertures 23, 24 are replaced by a single passage 24<SP>1</SP>. A flexible magnetized washer 35 secured to the cylinder 20 and disposed in the reservoir 1, collects steel particles present in the liquid and prevents emulsion. There are no cooling fins 25, but a dust cover 33 is arranged to pump air over the casing of the reservoir 1.

IPC: H02K23/20
Filed: 1935-10-12
Abstract: 469,092. Dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 12, 1935, No. 28215. Void. Convention date, Oct. 12, 1934. [Class 35] Cores; exciting.- A dynamo - electric machine, particularly a welding generator, has an n pole armature and a 2n pole field structure in which the flux is varied by armature reaction, the poles comprising a set of main poles 15 and a set of cross-poles 16 having exciting windings 17, 18 connected in series so that the voltage induced in the windings on one set of poles by reason of their magnetic coupling with the armature windings is substantially neutralized by the voltage similarly induced in the windings on the other set. As shown, the air gap 20 under the main poles 15 is twice that 21 under the cross poles 16 and accordingly, the number of turns of the windings 17 is twice that of the windings 18. Armature reaction acting in the direction AR has a component AM assisting the main pole flux, and a component AC opposing the cross pole flux so that a drooping characteristic is obtained. A series winding 22 may be placed on the cross poles to assist the armature reaction and this winding may be tapped to give any rate of change in the voltage across the brushes 13, 14 per ampere change in the load current. In a modification, the exciting windings 17, 18 are fed from the brush 13 and an auxiliary brush so that the generated voltage is due to the flux of the main poles. This flux is maintained constant by saturation in the armature, the main poles being provided with flux shunts and a series winding acting in the same direction as the winding 17. By increasing the turn ratio of the windings 17, 18 the size of the magnetic circuit may be reduced.

Title: Process for electrolytic oxidation of anions
Inventor: GLEIN WILLIAM KARL THEODORE
IPC: C25B3/23
Filed: 1965-07-05
Abstract: Anions contained in an alkaline electrolyte are electrolytically oxidized by the passage of D.C. through the electrolyte in the presence of a phthalocyanine compound.  The phthalocyanine compound may be dissolved in the electrolyte, e.g. if a sulphonic acid derivative is used; admixed with a solid particulate carrier, e.g. of carbon, silica, magnesia, alumina or mixtures of these; coated on or impregnated into the anode used, e.g. carbon or platinum.  Typically the electrolyte is aqueous NaOH containing dissolved mercaptides derived from treating hydrocarbon distillates to regenerate the hydroxide solution, the mercaptides being converted to disulphides, and the electrolysis may be effected while the electrolyte is still in contact with the hydrocarbon.  Water containing ammonium sulphide subjected to electrolysis under alkaline conditions is free of the sulphide with the formation of free sulphur.  Phenols, cresols and xylenols may also be anodically oxidized.  Specified phthalocyanine compounds are cobalt and vanadium phthalocyanines, phthalocyanine sulphonates and phthalocyanine carboxylates.  The oxidation may be effected at 0 to 100 DEG C. e.g. using an electrolyzer comprising 60 cells in series each with separate electrodes, e.g. of nickel-plated cast iron, separated by rubber-gasketed vulcanized asbestos diaphragms and having a port in each corner, the stack of electrodes and diaphragms forming four channels throughout the length of the electrolyzer. Spent caustic enters through the lower port of each anode plate and flows upward to the top port before it enters the anode outlet header.  A similar set of ports is provided for the cathode plates for circulation of caustic solution and release of hydrogen.
