PHD. 77-023 8.3.78 The invention enables the density distribution in a plane, in particular in a planar slice of a body, to be reproduced with the aid of scattered radiation. A narrow X-ray beam is then passed through the body to be examined. The scattered radiation produced in the path of said primary beam through the body reaches an array of detectors through a slot diaphragm which is disposed o...

A splicing head has a turbulence chamber which is circular in cross section. The turbulence chamber is cylindrical or has a cylindrical center portion and conical outwardly enlarging end portion, and an insertion slot. Air inlet passages open into the cylindrical portion along tangents and in opposite directions so that air under pressure through the passages creates circumferential flow in opposi...

A watchdog-type fail-safe system monitors program execution by a computer used, e.g., in controlling operation of an automative vehicle engine. The system includes a control unit, with a microprocessor; and a memory, which stores program segments. These segments include a main routine for performing a background job (BGJ), and a plurality of interrupt routines for handling event generated interrup...

Process for solid refuse disposal in which a vertical shaft furnace is maintained at 30-250 psia, part of the recycle-condensate is filtered to form liquid waste a portion of which is incinerated with a minor part of the product gas to form hot exhaust gas used to heat feed water in steam boiler zone, and energy from the resulting steam is recovered as part of the process energy requirement.

The invention relates to a heel holder for a safety ski binding, in particular for a safety ski binding for use in both cross-country skiing and downhill skiing. The heel holder has a bearing block fixedly oriented relative to the ski and a housing which carries a sole holder. The housing is supported for an upward pivoting movement about a transversely extending axis provided on the bearing block...

A safety ski binding is characterised by a jaw for fastening one of the ends of the boot, a pivotable plate, which is arranged below the boot sole and is movable relative to the ski about a vertical axis, and two lateral holding projections which interact with the side edges of the sole to prevent purely lateral displacement, the jaw being connected to the pivotable plate and being arranged so as ...

Behind an insertion slot 12, 13 an insertion mechanism for magnetic cards comprises a control member 2, 3 defining a passage 29 for the card, in alignment with the insertion slot. A magnetic head 22, positioned on one side of the passage, detects the position of the magnetic strips of the card, in order to deduce therefrom whether the latter is introduced in the correct position. A flap 4 can then...

An oriented polyester film coated on one or both sides with a crosslinked vinyl acetate polymer composition which renders the polyester film surface receptive to additional reprographic or matte coatings applied thereto, and to film containing the reclamation product of such coated film.

DRUM BRAKE AND ADJUSTMENT THEREFOR A drum brake includes a pair of brake shoes which are pivotally mounted on a backing plate by means of pins which extend from the latter. A pair of hydraulic actuators are also mounted by the pins and these hydraulic actuators are engageable with respective brake shoes In order to move the brake shoes radially during a braking application. A piston is slidab1y mo...

Process for the continuous recovery of solid polycarbonate from its solutions in organic solvents, consisting in: a) subdividing the polycarbonate solution by steam (water vapor) at either sonic or ultra-sonic speed by means of a De Laval type nozzle; b) conveying the dispersion thus obtained into a tubular heat exchanger having an increasing cross-section, preferably spirally-shaped or with elb...

A rubber composition, expansible under vulcanization conditions consisting of at least one vulcanizable synthetic rubber, vulcanizing agents and a propellant gas donor under vulcanizing conditions consisting of (a) from 100 to 900 parts by weight, based on 100 parts by weight of said synthetic rubber, of natural, non-pretreated chalk, and (b) from 5 to 120 parts by weight, based on 100 parts by we...

A binding agent setting even at temperatures below +8 DEG C., or also at temperatures substantially lower, is manufactured on the basis of cement clinker of high specific surface area and contains as admixtures forming water, compounds based on lignosulfonates, and, if need be, also further admixtures for preparation of mortars and concretes, as is sand, rough compact and porous aggregates, regul...

Inspection of micromask patterns occurs by both moving an inspecting laser beam relative to a micromask and varying the intensity of said beam in the same manner that occurs during pattern generation. The pattern modulates the inspecting laser beam by one of reflecting or transmitting a modulated laser beam therefrom. The modulated beam then is sensed and used to produce a modulation signal. The m...

Heat bondable bicomponent fibers useful in the production of nonwoven fabrics, comprise a latently adhesive component for forming inter- filamentary bonds upon the application of heat and subsequent cooling, and another component, and are characterized by the fact that upon the application of heat sufficient to melt the latently adhesive component and subsequent cooling, a substantial shrinkage fo...
