The effect of the scattered radiation produced on irradiating a body (K) with X-rays is eliminated by image reconstruction. This is achieved not by using a scattered radiation baffle in front of the detector field (DF), but by applying a solution to the physical problem. The number of scattered X-ray quanta is determined from the transport equation for the X-ray radiation. The detector measurement...

A microprocessor controlled system for monitoring, storing and periodically reporting on data pertinent to the commercial operation of a reporting system, such as a soft drink vending machine, to a central data collection and monitoring computer, and which periodically reports such data over a telephone line which it accesses on a nondedicated basis. The microprocessor controls operations of the t...

The heel support device has a non-expansible tension member (27) which can be moved in all directions and is designed in the manner of a belt, being secured by one end to the ski and by the other end, by means of a clamp (40), to a pin (47) on the boot heel. By means of this clamp (40) the tension member can be released at will, and can be pulled off from the pin (47) in the event of the occurrenc...

A film is disclosed, which comprises an at least uniaxially stretched finely cellulated polyester film of a high surface roughness having an apparent specific gravity in the range of 0.4 to 1.3 and an opacifying power of not less than 0.2, and a coating applied to either or both of the opposite surfaces of the polyester film. The coating applied to the minute-cellular polyester film serves the pur...

A toe iron of a safety ski binding has a basic body (11) which is to be attached to the ski and at which a sole-holder (13), which holds an inserted ski boot from above and from the sides, is mounted so that it can be pivoted up about a transverse axle (12) arranged in the front end region and at the bottom. The sole-holder has two lateral jaws (17, 18) which can be swivelled out laterally about v...

In a process for the separation of nitrogen from air, gaseous air is compressed in compressor 2, cooled and purified in a reversing heat exchanger 12, and then distilled in a single distillation column 32 to obtain a pure gaseous nitrogen overhead stream 34 and an oxygen enriched liquid bottoms stream 36. All of the bottoms stream 36 and a portion of the overhead stream 34 are passed to a condense...

The whole blood sample is obtained by connecting an at least partially transparent sample container to an in vivo locality and tran...

Method for manufacturing a compound pipe the wall of which comprises an inner layer (23) of a first material and an outer layer (24) of a second material. Powders (13,14) of the two materials are isostatically hot pressed to form a cylindrical tubular blank (15) in which the first material (13) forms an inner layer and the second material (14) forms an outer layer, the blank after heating to a sui...

Black acid or the sulfuric acid residue obtained in the manufacture of ethyl acrylate by reaction of ethylene and acrylic acid in the presence of sulfuric acid is heated and distilled in a distillation zone in the presence of a solvent to form an overhead mixture comprising an organic phase containing ethyl acrylate and solvent, and an aqueous phase containing water, solvent and acrylic acid.

Polycrystalline diamond has non-uniform quality along the direction of thickness. The diamond near the rake surface is of better quality. The diamond near the fixation surface is of worse quality. The worse diamond near the fixation surface alleviates a strong stress or absorbs an external shock. Owing to the worse diamond near the fixation surface, the diamond tool excels in chip resistance or to...
