The apparatus comprises a first apparatus part (8, 12) and a second apparatus part (16, 18) which is disposed on and extends outward from the first part. The second part is moveable with respect to the first part between an attracted position, in which it is extended to a predetermined extent, and a retracted position. in which it is extended to a lesser extent. The apparatus also comprises a sec...

The invention concerns an X-ray diagnostic apparatus with a motor-driven, vertically adjustable compression carriage, a means of support for a compression plate, and with a support plate for the object photographed. A means of support for a second closer to the focus, support plate and two support locations for the compression plate are provided, of which one is associated with the support plate w...

An internal lining for ducts (C) is provided by introducing into one end of the duct an assembly (E) which comprises a sleeve (5) and an inflatable system (2) and which is provided with heating means for applying a sheath (1) impregnated with a resin against the inner wall of said duct (C). After partial polymerization at least of the resin, the sheath (1) adheres to the inner wall of the duct. Th...

The adhesive contains an alginate and a polyvinyl acetate. In order to achieve a long-lasting effect, constant spreadability and long stability, the adhesive consists of a mixture of the alginate and of the polyvinyl acetate with carboxymethylcellulose, a methylcellulose emulsifier and a neutral oil emollient plus an alcoholic solvent, preferably 85% ethyl alcohol.

A magnetic head for a valve or the like is proposed, a connecting part for an electrical apparatus plug being provided on the magnetic-head housing. The apparatus plug can be fixed on the connecting part of the housing by means of a threaded screw which engages with a threaded part in a female thread on the connecting part. A contact screw for an earth-conductor plug part which engages in the appa...

Wheel slip control system of the present invention controls an output of an internal combustion engine during acceleration of a vehicle and controls a hydraulic braking device of a driven wheel during acceleration of the vehicle, determines a value representative of a cumulative time control of the hydraulic braking device is effected and compares the value with a predetermined value, and changes ...

Continuous process for converting hydrocarbons in the presence of a granular catalyst including a metal from group VI a, VII a or VIII, deposited on a carrier, comprising passing a charge of hydrocarbons with hydrogen through a series of at least two vertical catalytic zones in which the catalyst bed moves progressively downwardly, withdrawing progressively the catalyst from the bottom of the last...

A method and apparatus designed for the purpose of determining quickly and with high resolution the spatial distribution of radioactivity within an object emitting radioactive particles, especially those of low energy. A gas-filled position sensitive detector is used having an elongated electrode wire enclosed inside of and running the length of the detector. The object is placed inside the detect...

Chatter is suppressed in a solids-liquid separating centrifuge by including, in an external connection to a holder of the speed change gearing between the centrifuge bowl and conveyor, a spring and mass means which is torsionally resilient about the axis of the connection such that it will vibrate about that axis under chatter conditions at the chatter frequency, and which has a spring rate within...

An integral body tissue replacement product constituted by an at least partially degradable, flexible material comprising a polymer matrix having a porous structure, characterized in that the rate of degradation of the polymer of the matrix varies with the distance from the exposed surface or surfaces of the product; and a method of producing such product.

Fiber-reinforced thermoset polyurethane composites display enhanced impact strength when sufficient amounts of a high tenacity aliphatic polyamide fiber characterized by a drawn denier of 4 to 8 denier per filament; a thermal shrinkage of up to about 14 percent; an elongation of from less than 28 percent; and a tenacity of at least 5.5, preferably at least 7 grams per denier, are incorporated into...

Mechanically alloyed powder is produced in a gravity dependant ball mill by processing to a level at which the powder has a laminate type structure at 100X magnification. Consolidated products produced from the powder exhibit substantially the same desirable characteristics as are obtained form the consolidation of attrited powders having a featureless microstructure and/or saturation hardness.

An automatically controlled wagon, e.g. for a warehouse, comprises a camera (17) including a linear CCD or MOS image sensor (16) mounted such as to detect a guide zone (18) such as a reflective white tape provided on the ground surface (G), a circuit for detecting the lateral deviation of the wagon from the guide zone (18), and means for controlling the steering of the wagon according to the detec...
