The differences in wire strengths may be obtained by wires having different thicknesses, iron or steel wires of different carbon contents, wires made of different materials or wires having different numbers of elementary wires.

Abstract: A system for reconstructing a tomogram or a portion thereof of a cross-section of an object. Modified signal profile data obtained by exposing the object to a substantially flat beam of penetrating radiation from different angles and by preprocessing the transmission radiation received at positions respectively corresponding to the different angles of incident radiation is stored in an analogue form into a collection of primary record paths, each of which is uniquely related to an associated angle of incident radiation; whereas such information elements stored in various of said primary record paths as are included in a secondary path that is uniquely defined by position coordinates determinative of the radiation absorption or density of a certain element of the object cross-section, are integrated.

Abstract: A system for reproducing phase stereophonic signals, in which the audio signals applied to one or more inputs of the system are split up at each input to pass along two parallel paths. Each of these paths includes a frequency-dependent, phase-shifting means, and the phase-shifting means of each pair of paths are interconnected through a potentiometer. The output signals of each pair of phase-shifting means are respectively applied to two reproducing devices. The phase-shifting means may be arranged for individually frequency-dependent operation.

Abstract: An apparatus for producing preforms for the production of optical fibers by plasma coating and drawing. A plasma stream produced with the aid of a radio frequency generator is caused to successively pass through three zones in the first of which a mixture of fluidized powders of two materials of appropriate composition is injected and completely vaporized. In the second zone an oxidizing gas having a mixing action is introduced into the deeply cooled stream. The materials and gas react with each other to form microseeds. The powders contain high purity silicon and at least one doping element of the group comprising Al, Ge, B. Ti and Zr. In the third zone an inert gas is introduced and deposition of substance is effected on substrates suitably arranged with respect to the path followed by the plasma stream.

There are also provided recording means for the glycemia 14 and a sound alarm.

Abstract: A closed food processing vat particularly for use as a cheese curd vat where at least one rotatable vertical shaft within the vat has a pivotally associated cutter frame stopped so the frame when the shaft is rotated in one direction is moved to a cutting position extending as a radius from the shaft with the cutting edge of the blades in the frame leading to a stirring position when the shaft is rotated in the opposite direction with the frame automatically moved as a reaction against the product in the vat to a position at an angle to the radius so that the projection of blades in the frame relative to the direction of rotation is increased to stir the product.The present invention relates to food processing apparatus which has been particularly although not solely designed for use in cheese making.

Abstract: Transfer of a powder image from a material carrying the image, such as a photoconductive material utilized for indirect electrophotographic copying, is effected magnetically by employing magnetically attractable developing powder for forming the image and bringing the powder image while under the influence of a magnetic field into contact with a first receiving support that comprises a myriad of zones of a first material which are separated from each other by a second material, one of these materials being magnetizable and the other being not magnetizable. The materials preferably are metals giving the first receiving support a durable smooth surface. The zones of the first material have a diameter and inter-distance of, at most, about 5 times and preferably about 1 to 2 times the diameter of the largest powder particles to be transferred, so usually of about 50 to 100 microns.

Abstract: The invention relates to a centrifugal compressor comprising an impeller not comprising distributor blading upstream of the impeller, a pressure probe and regulator means controlled by the probe and arranged to act on the flow conditions downstream or upstream of the compressor to avoid the risk of surging.

Abstract: A device for investigating surface phenomena by field emission contains an emission point in an evacuatable enclosure facing a fluorescent screen. The point is desorbed by a first pulse which produces sufficient heating of the point to attain substantially complete desorption and field emission or field desorption is produced by a second pulse spaced a controllable time after the desorption pulse. Repetitive measurements are possible by producing a train of the first and second pulses during which parameters can be varied and the results observed. Methods are disclosed for determining the temperature of the point from the measured field emission both by relating field emission to temperature and by relating temperature to desorption.

Abstract: Molten slag is granulated with water to produce a granulated-slag/water sry that is fed into the bottom of a horizontally extending foraminous drum. This drum has radially inwardly extending vanes and is rotated to lift up the granulated slag and separate it from the water, discharging the slag onto a conveyor belt for storage or further use. The water running out of the slag slurry is recirculated for use in the initial granulation step for the molten slag stream.
