Title: Improvements in preformed building blocks
IPC: E04B2/14
Filed: 1944-04-06
Abstract: 577,052. Building blocks. CHARITY, E., and HARRIS, A. April 6, 1944, No. 6459. [Class 87 (i)] [Also in Group XV] In a building block comprising at least three spaced-apart layers A, B, C, the inner layer B is displaced horizontally and vertically relative to the outer layers A, C to provide projecting portions b, b' and corresponding recesses b<2>, b<3>. The layers are spaced apart by vertical members D which are displaced less than the layer B. The members D on one side of the layer B may be grooved at d for ventilation. Corresponding blocks are provided for corners, wall junctions and wall intersections. In a modification, particularly for moulded plastic toy blocks, the layer B is of inverted channel shape.

Patent GB-261968-A (GB)
Title: An improved stop-cock
IPC: B60T17/04
Filed: 1926-03-13
Abstract: 261,968. Ackermann, G. March 13, 1926. Multiple-way valves.-In a combined rotary spherical, lift, and rotary cylindrical multiple-way valve for use in compressed-air couplings, the axes L, S of the tube connecting unions are disposed at an obtuse angle to give a large swing from the closed position, shown in the Figure, to its open position. In the closed position a lateral arm m of the upper hollow pivot is raised upon a cam fillet t formed on a fixed disc g; this holds open the lift closure p and vents the interior of the valve to atmosphere through ports r, l in the rotary cylindrical valve formed by the hollow bottom pivot. On opening the main valve, the initial movement causes the arm m to ride off the fillet t to close the lift valve p, and also closes the cylindrical valve ports at r, l, thereby isolating the interior of the valve from the atmosphere. The open and closed positions of the valve are located automatically by means of a roller o on a key slide n which is pressed against a cam surface v by a spring located inside the upper hollow pivot. From either the open or closed positions the roller o mounts the cam v, and after passing the crown of the cam runs down on the other side and definitely locates the next position of the valve.

Bubble cap units according to the invention may be of circular cross-section, as shown, or of oval or polygonal cross-section for use in oval or polygonal columns.
Patent GB-398226-A (GB)
Title: Improvements relating to films for photographic purposes
IPC: G03C1/795
Filed: 1932-03-09
Abstract: In producing film supports of the kind described in Specification 378,394, consisting of a core of gelatin hardened as with formaldehyde and coated on each side first with a layer of rubber and then with a layer of celluloid, collodion or other varnish, the rubber layers are slightly vulcanized before the application of the varnish, as by passage through the vapour of bromine at from 60-70 DEG  F., in order to increase the resistance to moisture, the tensile strength and the flexibility of the film. The resistance to moisture may be further increased by adding to the rubber coating solution about 2 per cent of a mineral oil or fatty substance such as petroleum jelly.  As the vulcanization removes the tackiness of the rubber layers, proper adhesion of the varnish layers is ensured by adding 10 per cent of a rubber solvent to the varnish coating liquid. The core is preferably formed as described in Specification 398,288 from a solution of gelatin containing potassium bichromate and exposed to light after casting.

Title: Process for the thermal decomposition of hydrocarbons
IPC: F04B35/00
Filed: 1931-03-06
Abstract: Hydrocarbons are decomposed, particularly to acetylene, by means of an inverted flame produced by the introduction of oxygen or an oxygen containing gas into an atmosphere of the entirely gaseous hydrocarbon in the absence of liquid or under the surface of the liquid hydrocarbon to be decomposed.  The oxygen or oxygen containing gas is introduced through one or more jets into a vessel through which the hydrocarbon is caused to flow.  Examples are given of the burning of oxygen or air in a stream of natural gas and of oxygen under the surface of gasoline.  Kerosene, lubricating oils, &c. are treated in the same way.  More acetylene is produced per unit of oxygen consumed when the jets are of small diameter and when arranged as a plurality of jets in a group in a single vessel.  Specifications 264,845 and 265,234, [both in Class 2 (i), Acetylene], are referred to.

[Class 70] Rubber is treated so as to give it oil-and solvent-resistant qualities by causing it to react with dithiocyanogen, in amount such that up to 50 per cent. of the amount necessary to cause complete saturation becomes combined. The products may be vulcanized by heat alone or with addition of sulphur and accelerators. The reaction is carried out in solvents such as benzene or carbon tetrachloride. Small proportions of other substances which react with rubber such as halogens, hydrohalides or thiocyanogen derivatives may be added. Plasticizers such as thio-#-naphthol, or dibutyl thio-diglycollate, and substances which reduce the viscosity of rubber solutions such as thioglycollic acid, p-toluene sulphinic acid, phenylbydrazine or trichloracetic acid may be added.

Abstract: 1536196 Centrifugal separators BAYER AG 25 Feb 1976 [26 Feb 1975] 07404/76 Heading B2P A spray dryer is provided with a built-in centrifugal separator for separating solids from the drying gas used in the dryer. In Fig. 1, solids-laden gas leaving the active or drying chamber 1 of the dryer is caused by swirl-producing vanes 3 arranged around a cowl 2 to rotate in a lower conical part 6 of the dryer 10 that the solids are separated by centrifugal force against the wall of the part 6 and collect at its bottom for removal through an outlet 8 whereas the clean gas is evacuated through a central vertical pipe 4 and a pipe 5 leading radially from the latter. A conical dome 7 prevents reentrainment of solids in the upward flowing gas. The vanes 3 may be flat or curved. In Figs. 3 and 4a, the pipe 4 opens into a frustoconical, or alternatively cylindrical, chamber 9 provided beneath the cowl 2 and communicating with clean gas outflow pipes 12 leading to a collector ring 13 having an outlet conduit 14. Swirl-producing plates 10 are provided on the pipes 12 to create rotation of the solids-laden gas. The pipes 12, as shown, are of circular cross-section, and are provided with holes or slits 11 through which a particular flow of the solids-free gas or of gas having a low content of solids takes place. Alternatively the pipes 12 are of oval cross-section. In Fig. 5, a hollow vane is used instead of outflow pipes 12 with a takeoff hole and/or slit 16.

The circuit-breaker of Specification 809,187 is arranged to have one or more immediate reclosing operations followed by delayed reclosing operations. To effect the immediate reclosing operations, the counter 216, Fig. 2, is provided with an adjustable cam member 246, which in the arrangement shown, closes a switch 213 on each of the first two steps of the upward movement of the counter 216.

In this arrangement the time-delay devices 32 for delaying the tripping of the circuit-breaker are rendered ineffective for the initial tripping operations by a further adjustable cam member 243 on the counter 216. The member 243 acts through a member 190 to disconnect the devices 32 for the first one or two opening operations.
