Filed: 1936-05-06
Abstract: 462,939. Gas producers. KRUPP AKT.-GES., F. May 6, 1936, No. 12786. Convention date, May 13, 1935. [Class 55 (i)] A shallow gasefication zone of conical or disc form is obtained by the use of a central air inlet pipe and an annular outlet or series of outlets for the gases at the periphery of the fuel shaft, the direction of gasefication being reversible. The lower part of the shaft 1 is narrowed by a lined portion 2, between which and another lined conical portion 3, is an annular perforated ring 4 surrounded by a channel 5 of spiral formation. The lining 6 protects the ring 4 from damage by the descending fuel, and the passage of gas through the ring is controlled by a sleeve valve. The air, or air and steam, may be supplied, due to suction from an internalcombustion engine from below through a pipe 7, the upper end of which is protected by a firebrick hood 8 adjustable in relation to the pipe 7, a sleeve valve 11 controlling the air inlet to the pipe 7. The air blast takes place transversely across the base of the fuel bed, or, if the pipe 7 is raised, obliquely downwards, and the combustible gases are withdrawn through the ring 4 and pass through a heat-exchanger 20 in which circulates water from a jacket 21 in the upper part of the shaft, the steam generated entering by pipe 17 and mixing with the air. Slag is removed through openings 19 in a space 18. The direction of gasefication may be reversed, the air being supplied through the annular ring 4 and the combustion products withdrawn through the pipe 7.

TALBOT-, Raheen, Chesters Road, Bearsden, Dumbartonshire. May 6, 1932, No. 13086. [Class 34 (ii).] A revolving drum through which passes material subjected to the drying action of hot air or gas introduced through the circumferential wall of the drum is constituted as a perorated shell which is machined externally so as to be truly cylindrical and smooth. The drum may be formed in sections aligned and interconnected by flanged rings. The hot gas is introduced into the drum through elongated supply ports each of which is narrow circumferentially of the drum but may extend nearly the whole axial length of one division of the drum. The ports are framed with wide sealing flanges conforming closely to the curvature of the drum and approximated closely to the drum to minimize gas leakage. These flanges are constructed as or backed by ducts for cooling water, and may be faced with wired asbestos composition or like fibrous material. As shown in the drawings, the perforations in the drum 1 are countersunk on the inner surface, and the flanges 4 of the gas supply ports 3 are faced with fibrous material 5 and cooled by water entering by the port 6 and leaving by the port 7.

Title: Manufacture of Asbestos Hydraulic Cement Pipe
IPC: B28B21/48
Filed: 1968-03-19
Abstract: 1,181,613. Asbestos hydraulic-cement pipes. JOHNS-MANVILLE CORP. 19 March, 1968 [31 March, 1967], No. 13137/68. Heading F2P. A method of forming asbestos-hydraulic cement pipes, so that they do not sag, or slump, before completely setting, comprises providing a furnish of a water suspension of the ingredients including asbestos fibre and hydraulic setting Portland cement, forming a thin wet sheet of the ingredients, superimposing layers of the thin wet sheet to form a laminated tube body, by winding the sheet convolutely of a rotating mandrel, and consolidating the laminated body into a monolithic mass wherein there is applied to the thin wet sheet of ingredients a dilute aqueous solution, between 0.01 to 2.0% by weight based upon the total weight of the dry stock solid ingredients of the furnish, of at least one of the following compounds, monoethanolamine, diethanolamine or triethanolamine. The furnish comprises 10-40% of asbestos fibre; 10-50% of silica; and 30-70% of Portland cement, the monolithic mass being either cured by air, or steam. In manufacturing an asbestos Portland cement pipe a thin wet sheet of the asbestos-Portland cement stock ingredients, typically collected from a dilute aqueous slurry of the components with a filter screen activated by pressure differentials, is superimposed by convolute winding on a rotating mandrel and consolidated therein by the application of pressure into a continuous mass, application of the alkanol amines, monoethanolamines, diethanolamines, or triethanolamines, or mixtures thereof, being administered to the thin wet sheet following its formation by collection upon a filter screen and, before it is convolutely wound upon the mandrel. Triethanolamine is preferred because it achieves optimum retardation of sag with a minimum of adverse effects, the application being achieved, e.g. by spraying; overflow troughs, distributers, roll applicators &c. The alkanol amines are water soluble and are applied in aqueous solution of a concentration of about 0À1 to 5.0% by weight of the aqueous solution. Sag cake tests for eight examples of cement - asbestos - alkanol amines are tabulated in the Specification. Comparison tests for pipes are also described.

Title: Improvements in and relating to radiation gauges
IPC: G01N23/16
Filed: 1961-04-13
Abstract: 921,397. Beta radiation gauges. INDUSTRIAL NUCLEONICS CORPORATION. April 13, 1961 [April 14, 1960], No. 13398/61. Class 40 (3). In a beta radiation absorption gauge, variation of the gauge sensitivity with the atomic number of the material through which the radiation to be measured is transmitted is compensated by making use of the fact that when the transmission of beta radiation through the measured material decreases as a result of an increase in the effective atomic number thereof, there is a concomitant increase in the radiation which is generated when the beta-rays bombard the atoms of the material. In carrying out the invention, means are provided for deriving an indication which is representative of both the transmitted beta-rays and generated X-rays, and further means are provided for adjusting the relative magnitudes of the two contributions to the indication so that the decrease in beta radiation is effectively cancelled by the increase in X-rays. In a first embodiment, Fig. 11, beta radiation transmitted through a material 20 from a source 24 is detected by a detector 22a whilst a further detector 22b detects the generated X-radiation, the two detector outputs being added and applied to an indicator 28. An absorber 94 of critically selected thickness is interposed before detectors 22a so as to adjust the magnitude of the detector output to achieve the desired cancellation. In a second embodiment, Fig. 12, the detector outputs are applied through individual amplifiers 96, 98 to an adding amplifier 100, and a potentiometer 102 is included in the output from amplifier 96 to permit the beta radiation contribution to be controlled to achieve the desired cancellation. In a third embodiment, Fig. 13 (not shown), the two detector outputs are combined with a fixed resistance attenuating network interposed in the connection from the beta radiation detector. In a fourth embodiment, Fig. 14, a common detector, e.g. an ionization chamber, is employed to detect both the beta and X-radiation and an absorber 94 is provided to control the beta radiation contribution. The absorber may be formed integrally with the detector window 22w. The Specification discusses the application of the invention to a particular manufacture of sheet material. It is desirable that the beta radiation source should produce the minimum of X-radiation and the Specification discusses in general terms the construction of a source to achieve this. U.S.A. Specification 2,829,268 is referred to in connection with the stabilization of amplifiers, such as those employed in Fig. 12.
