Title: Method of manufacturing ºÔ-cresol and ºÔ-methyl acetophenone
IPC: C07C39/07
Filed: 1964-02-14
Abstract: p-Cresol and p-methylacetophenone are prepared by oxidizing an isomeric mixture of 1,1-di-tolyl-ethanes mainly consisting of 1,1-di-p,p1-tolylethane with molecular oxygen in the presence of an alkali at 60 DEG  and 160 DEG  C. such that the conversion of 1,1-di-p,p1-tolylethane does not exceed 40% by weight, decomposing the resulting hydroperoxide with acid giving p-cresol and p-methyl acetophenone and recovering the unreacted 1,1-di-tolylethanes containing other isomeric components than 1,1-di-p,p1-ditolylethane in a more concentrated state. Suitable alkaline catalysts are carbonates, bicarbonates, organic salts and hydroxides of alkali metals and hydroxides of alkaline earth metals.  Suitable acid catalysts for the decomposition of hydroperoxide are mineral acids in concentration of 10 to 20% at 60 DEG  to 100 DEG  C.

Title: Improvements in or relating to projection screens
IPC: G03B21/60
Filed: 1939-02-28
Abstract: 525,750. Projection screens. TURNER, E. G. Feb. 28, 1939, No. 6515. [Class 97 (i)] The metalized surface of a projection screen is rendered more light-dispersive at the sides than at the centre. Fig. 1 shows a duck or canvas screen, held by lashings 12 to a frame 13, and treated first by the application of a flexible filler to produce a smooth surface, then sprayed with paint, and, while the paint is still tacky, with sand particles. No sand particles are applied to a central strip 16. Particles passing through a 100 mesh to 60 mesh screen are applied to strips 18, the quantities being such as to cover only a small part of the surface near the strip 16, and being graduated to cover up to about 50 per cent. of the area at the outer edges of the strips 18. Particles passing through 60 mesh to 30 mesh screens, up to those retained by a 1/32 of an inch mesh, are applied to strips 19, the particles being more or less uniformly distributed to cover about 10 per cent. of the areas 19. Alternatively, the particles applied to the strips 19 may be similar to those applied to the strips 18, and be spaced to produce the required graduation of light-dispersive property. Aluminium paint is sprayed on to the surface when it has dried. In a modification, the strips are replaced by annular areas. Fig. 5 shows a modification in which the warp threads 24 of the fabric progressively increase in size across side areas of the screen from a central area in which they are uniform. A filler 14, paint layer 15, and a coating of aluminium paint 20 are applied to the fabric. According to the Provisional Specification the screen surface may comprise glass beads.

Filed: 1928-03-05
Abstract: 312,411. Alger, C. A. H., and Barker, E. G., (trading as Barker & Co.). March 5, 1928. Cupping.-In apparatus for forming corrugated paper cups usable as cake or cooking containers of rectangular, triangular, oval or other shape having corners or parts of small curvature, the grooved faces of the dies 6, 8 for corrugating the side walls of the container are so framed as to cause the material to be drawn away from the corners towards the centres of the sides, for example, in the case of a rectangular container. In one construction the face of either of the dies 6, 8 is made slightly convex as shown, and in addition to or in lieu of this, the grooves on the dies 6, 8 are of less width adjacent to the corners. The dies 6, 8 are circular in plan with central apertures 4, 9 of the configuration of the container. The aperture 4 is grooved for engagement with similar grooves 12 on a plunger 11 on which the die 8 is slidabdy mounted and which is received in the aperture 9 when inoperative The grooved sides of the plunger 11 may converge downwardly if desired.

Abstract: 773,533. Valves. CALOR GAS (DISTRIBUTING), CO., Ltd., TAYLOR, T. H., and OLIVER, F. D. May 9, 1955 [March 9, 1954], No. 6827/54. Class 135. A valve suitable for gas storage cylinders consists of a spring-loaded closure member 2 coacting with a seat 3 towards which it is moved by a stem 18 which is engaged by a hand wheel 14 having screw-threaded connection with the exterior of the casing, the closure member and the stem 18 being separated by a sealing diaphragm 16 which is clamped in the casing by a plug 15 having a central bore through which the stem 18 passes. The arrangement is such that there is no direct connection between the diaphragm clamping member 15 and the hand wheel so that the member 15 does not tend to be loosened by operation of the valve. A lubricant retainer in the form of a felt pad 19 is situated under the hand wheel 14 and the latter has an oil hole 20. A retaining ring 21 prevents the hand wheel from being screwed off the casing.

Filed: 1942-05-21
Abstract: 572,926. Automatic guns. BIRMINGHAM SMALL ARMS CO., Ltd., FAULKNER, H. A., and WACKROW, R. D. May 21, 1942, No. 6906. [Class 119] [Also in Group XXV] Pin fastenings for securing parts of automatic guns, such as the barrel or stock, are retained by spring means which also serve to prevent complete removal of the pin. A barrel-looking pin 1 is shown, whereby the barrel 8 is looked to the breech-body 10 of the gun. The pin is formed with a tapered groove 3 adjacent the knob 2 and a second similar groove 3a, but with reversed taper, near its inner end. A spring retainer 14, of the shape shown in Fig. 3 (section on line A-A), encircles a boss 11 on the breech-body and engages by its arm 15, located in a slot 13 in the boss, with the groove 3 when the pin is in barrel-looking position. When the pin is pulled outwards, the tapered wall 4 of the groove forces the spring arm 15 outwards, and the pin may be withdrawn until the groove 3a is opposite the spring, which thereupon engages in the groove and prevents further withdrawal of the pin. On pushing the pin inwards, the taper 4a of the groove disengages the spring.
