Title: Recording sounds photographically on films for colour photography
IPC: G03C7/24
Filed: 1932-10-31
Abstract: 393,844. Combined sound and colour picture films. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Oct. 31, 1932, No. 30541. Convention date, Nov. 28, 1931. [Class 40 (ii).] Sound is recorded photographically on a bi-pack, in which two films are united with their light-sensitive emulsion layers adjacent to each other but separated by a filter layer which is dyed with a colour complementary to a colour to which one of the emulsions is sensitized. According to the invention, the film bearing the special colour-sensitive layer is arranged on the side nearer the objective, and the sound is recorded on this film through its support. Erythrosin may be used for sensitizing the emulsion layer of this film to the yellow-green part of the spectrum, a red filter layer consisting of an alcoholic solution of aurin being applied to the said layer. A panchromatic emulsion is used for the second layer.

Abstract: 1,074,837. Adjusting flow of gas through a gas lighter. S. T. DUPONT. Aug. 4, 1964 [July 31, 1963; July 21, 1964], No. 31071/64. Heading F4F. In a gas lighter the flow of gas through wick 4, bores &c. 16, 17, 18, 19, 20 to the burner is controlled by the degree of compression of a elastic pad 8, Fig. 1, which is compressed by screw member 13 acting through valve member 10. The gas passage is closed by a pad 14 on plunger 11 and is opened by gas pressure when the force exerted on plunger 11 by lever 15 is relieved. A cam 23 is fixed to the upper end 22 of member 13 and has a slot 29, Fig. 2, for the head 28 of a screw 27, Fig. 4, which attaches a slide 26 to a block 24 having a serrated edge 24a for engagement by an operator. An extension 30 of slide 26 has an inclined undersurface 30a in engagement with lever 15, whereby as the slide moves pressure is relieved or increased on plunger 11 to open or close the valve. Movement of the slide moves head 28 in slot 29 to rotate cam 23 to compress pad 8. When the head 28 reaches the Fig. 3 position further movement produces no further rotation of the cam so that the pad cannot be crushed. Other shaped cams are shown, including a rack-and-pinion mechanism and rotatable members moving a head similar to 28 or a worm mechanism.

Abstract: 736,815. Rotary-disc valves. DAVEY, PAXMAN & CO., Ltd. Dec. 8, 1953 [Dec. 8, 1952], No. 31095/52. Class 135. In a rotary disc valve for a rotary suction filter and comprising superposed, ported, seat and obturating members, the seat member is provided with one or more shutters 16, 21 which can be actuated from outside the valve casing to adjust the end limits of one of the ports and so vary its effective area. The shutters shown are radial and work in a recess which extends from the two ends of the port 8. Shutter 16 is carried by a rotatable ring 17 which is provided with a handle 19 and carries a cover 20 for the slot in which the handle moves, and shutter 21 is carried by a central shaft 24 which is extended to the rear of the valve and carries an operating handle 25. Oil retaining grooves 14 in the face of the seating plate are provided for lubrication purposes. The invention is shown as applied to a filter of the drum type wherein the obturating disc is formed on the face of one of the drum trunnions and the seating disc is carried by a head member to abut against the obturating disc. The compartments of the drum are connected by conduits through the trunnion to the ports in the obturating disc, and the ports in the seating disc are connected to sources of maxmum suction, reduced suction, and compressed air.
Patent GB-721863-A (GB)
Title: Improvements in or relating to spinning nozzles
IPC: D01D4/02
Filed: 1952-12-08
Abstract: <PICT:0721863/IV (a)/1> A spinning nozzle comprises a plate provided with apertures through which spinning solution may be extruded, and a nozzle cap or head secured to the plate by shrinking it thereon.  The plate and cap may be made of metal, glass, porcelain or plastic material, e.g. gold-platinum or gold-palladium alloys or phenol-formaldehyde condensation products.  The plate may be formed from a bundle of metal rods which are welded together and then cut transversely to their longitudinal axis.  The nozzle may be made by heating a metallic nozzle cap, inserting a nozzle plate into the hot cap, and allowing the assembly to cool so that the cap contracts and grips the periphery of the plate with sufficient force to withstand the high pressures of the spinning solutions. To achieve satisfactory sealing against fluids under pressure, the contacting surfaces of the cap and plate should be smooth and accurately constructed.  If desired, the fit may be improved by application of a sealing lacquer. The strength of the nozzle is improved if the plate is made not of flat but of slightly curved, e.g. concavo-convex, shape.  The edge of the plate is preferably made slightly conical, e.g. the angle of conicity may be 2-25 degrees, and the contacting surface of the cap is made of a corresponding shape.  Alternatively, the edges of the plate may be curved spherically.  The plate may be made with a beaded edge to avoid the adherence of gas bubbles at the corners between plate and cup during the spinning-operation.  As shown, a plate 1 provided with spinning orifices 2 is assembled in a cap or head 4 which has been heated and then shrunk on to the plate by cooling. The plate is of concavo-convex shape, and its edge 3 and the contacting surface of the cap are conical.  Instead of providing the plate with a beaded edge, the edge may have a collarpad-, roll-like or other shape which will prevent the adhesion of bubbles.  If desired, several perforated plates may be united with and within a single spinning cap or head.  The cap may be of brass and the plate may be of glass.

Title: Process for the production of substituted aromatic compounds
Inventor: COUNT DAVID JAMES LE
IPC: C07C37/52
Filed: 1965-07-22
Abstract: p-Cresol is prepared by a process comprising: (a) converting toluene and a mixture of o- and p-iodotoluenes into ditolyl iodonium salt containing a weakly nucleophilic anion by forming the iodoso derivative of the iodotoluene and reacting this derivative with toluene in the presence of a strong acid such as sulphuric acid; (b) hydrolysing the iodonium cation of such salt to form a cresol fraction and an iodotoluene fraction as essentially sole hydrolysis products; (c) recovering and recycling the product iodotoluene fraction for use in feed iodotoluene for a repeated sequence of conversion, with fresh toluene, to iodonium salt and hydrolysis of the salt; (d) repeatedly recovering and recycling iodotoluene; (e) attaining a steady state condition at which the proportion of p-iodotoluene in the product and feed iodotoluenes remains substantially constant, the feed then containing at least 60% of p-iodotoluene resulting in a cresol fraction containing more than 85% of p-cresol; and (f) isolating p-cresol from the product cresol fraction.  The p-iodotoluene is converted into the corresponding iodoso compound by treatment with a peroxide, e.g. an organic peracid. The hydrolysis step is preferably carried out by adding water to the strongly acid solution of the iodonium salt and boiling the mixture in the presence of a cuprous salt, e.g. the chloride.

Abstract: 624,882. Cutter mechanism for tufted fabric looms. BRINTONS, Ltd., and BRINTON, C. C. Oct. 22, 1946, No. 31312. [Class 142 (ii)] A tuft cutter, comprising a cutter comb 19 reciprocated between a plate 17 and a fixed comb 21, has the combs 19, 21 made up of short sections assembled end to end and loaded by springs 34 (two for each section). The spring pressure is localised at the cutting edges by recessing the plate 17 to clear the upper part of the comb 19, and by providing studs 23 (one for each section) for the top of the comb 21 to rest on. The cutter comb is actuated by a bar 12, from which studs (not shown) project through slots in the plate 17 into holes in the cutter comb sections. When the cutter is clear of the tuft yarns 7 (as shown) the bar 12 is disconnected from its driving mechanism, but becomes coupled to it as the cutter is lowered. Specification 624,883 is referred to.
