This application describes a rotation-only CT scanner with beam deflections; the deflection and the rotation being so related as to permit the derivation of absorption data in groups focussed on respective "pivot points" outside the detector locus. Data derived from different detectors, but focussed on the same pivot point, relate to groups of paths, some of which overlap, and the overlap is used ...

Method and device for joining together an upper and a lower thread, which includes moving at least one first thread feeder from a thread pick-up position to a thread transfer position, inserting the upper and the lower threads into a longitudinal slot formed in a chamber, holding the threads in the slot until compressed air is admitted to the chamber, and at given positions during the movement of ...

A process is provided for mechanically surface-finishing a textile fabric which comprises ccontinuously feeding said fabric from a source of supply, such that said fabric lies in a single plane, subjecting successive adjacent sections of the fabric to intermittent mechanical impact with an abrasive means across the width of said fabric thereby avoiding substantial sustained contact between the fab...

Sintered silicon nitride articles are prepared by sintering a silicon nitride compact of a density of at least 1.3 g/cm3 in nitrogen gas atmosphere at substantially atmospheric pressure, while the compact is embedded in a protective powder comprising silicon nitride, boron nitride, or a mixture of silicon nitride and boron nitride, and one or more sinterization additives for silicon nitride, said ...

PURPOSE:To make it possible to exhibit a desulfurizing effect using inexpensive matterials and to obtain an amount of sulfur dioxide gas evolution similar to that of kerosine, by forming a carbonaceous fuel containing Ca(OH)2, CaCO3 or dolomite and K2CO3. CONSTITUTION:100pts.wt. carbonaceous fuel is blended with 3-20pts.wt. desulfurizing agent comprising at least one compound selected from among C...

A spring brake actuator for a rail vehicle brake unit, comprising a cylinder and a rod shaped member. The actuator includes a cylinder-shaped housing, a piston with a piston rod and a spring intended to act in a brake applying direction. In order to obtain a truly modular system the actuator, as an integrated and self-contained unit, is arranged on the rod-shaped member of the brake unit. Its hous...

The fossil-fuel fired vapor generator has a vertical flue formed of vertical tubes and a funnel at the bottom end which is formed by helically extending tubes. In addition, the helically extending tubes are in communication with the vertically extending flue tubes via bifurcation elements in order to convey the working medium upwardly into the flue tubes. The flue may be of rectangular cross-secti...

A gradiomanometer 1 measures the difference in pressure between points 3 and 4 to indicate density and hence proportions of two phases (e.g. liquid and gas), each of known density flowing as indicated by arrow 6. A venturi meter 2 measures the difference in pressure between points 4 and 5 to indicate flow rate, initially assumed to be that of the heavier phase only. An iterative calculation makes ...

It is often desirable to meter multiphase fluid flow in pipes (e.g. bore holes). In order to obtain reliable/accurate flow rate measurements it is known to incorporate obstructions in the flow path to cause homogenization. A non-obstructive method of homogenizing the flow of a multiphase mixture of fluids in a bore hole comprises providing in the bore hole a pipe section which has an internal surf...

A first channel including filter 1 and photodetector 2 senses emission from a flame in the wavelength range below 6 mu particularly that characteristic of carbon dioxide and produces signals to be used to operate alarm means. A second channel including filter 9 and detector 10 senses spurious emission produced by other thermal radiators in the wavelength range of a long-wave spurious emission abov...

The use of a small amount of a polyhydroxy containing anthraquinone compound in a rubber ply or skim stock greatly improves the humid aged adhesion of the rubber stock to brass plated steel cords or fabric. This invention is particularly useful in tires with steel cords or belts. The following formula describes the anthraquinone compound: where two of the R's are hydroxyl radicals and th...

A dry mixture is made of a non-modified fluorinated polymer, particularly a deformable, web-forming polytetrafluoroethylene, in powder and/or fibre form, an inorganic hydrophilic material as a powder and a porous hydrophilic material or a pore forming agent. The mixture is pressed into a cake. The cake is subjected to rolling steps. Between rolling steps the cake is turned over an angle.
