Abstract: A method for contour recognition of completely or partly transparent objects (2), e.g. containers like glass or plastic bottles, the object being advanced through an illumination and detector station (3-13; 3, 4, 20, 21) and there being illuminated on at least part of its circumference. The light reflected by the object (2) is viewed by a detector (4,3) against a background that is dark relative to the object, and the viewed image is recorded and converted to pulse signals that are processed to yield a numerical code characteristic of the object. During recording distinct signals are generated which are characteristic of the width (b.sub.n) of the object relative its corresponding height (h.sub.n) for a number of levels (n). The signals are then processed in a threshold circuit (24) and a pulse generating circuit (25) for the generation of the pulse signals (P), for each height (h.sub.

Abstract: In a composite window comprising a skylight component and a wall component, the top member (4) of the frame of the wall component presents an upstanding ridge (7) which engages a groove (9), triangular in cross-section, in the bottom member (8) of the skylight frame so as to tiltably support the skylight component. On their outer faces the frame members (4,8) are weather protected by a covering including an angular gusset plate (13) being in overlapping relationship with two covering members (10,12) mounted on the frame top member (4) and the frame bottom member (8), respectively, the angle and the overlapping of said gusset plate (13) being adjustable dependent on the angle between the frames (2, 3) of the wall and skylight components, respectively.

Abstract: The magnetic tape recorder exhibits an insertion channel into which a cassette containing a magnetic tape is inserted in a longitudinal direction. A capstan driven by a tape drive motor and a magnetic head are disposed at one side of the insertion channel. A dust cover for the cassette is hinged out by a pivot arrangement during closing of a cover for the insertion channel. The magnetic head is disposed on a magnetic head carrier that is pivotable around an axis and is coupled with the cover for the insertion channel such that the magnetic head is pivotable into place behind the dust cover in contacting relation to the magnetic tape after said dust cover has been opened. The cassette is locked in a defined working position after the cover for the insertion channel is closed. For removal of the cassette, the magnetic head is pivoted out of its operating position into an idle position as the cover for the insertion channel is opened, whereupon the dust cover is hinged back into its closed position.

Abstract: Substantially spherical solid particles of a substantially uniform particle size are prepared by dispersing a solution of a polymerizable substance in a first liquid by means of a suitble emulsifier to form droplets of the polymerizable substance of a substantially uniform particle size, which are thereafter poured into a second liquid with which the first liquid is immiscible and which contains a sufficient amount of a reactant to polymerize the polymerizable substance. After the polymerization the substantially spherical particles formed are recovered. In a preferred embodiment, an aqueous solution of an alkaline metal silicate, especially sodium silicate, is dispersed in a coparaffinate by means of a suitable emulsifier, and the emulsion is poured into an aqueous solution of the polymerization reactant to form gelled, substantially spherical hydrated silicate particles.

Abstract: In a gas distribution arrangement the processing gas is admitted from a helical inlet duct through an annular orificial slit into a space between two coaxial guide walls. Guide vanes are provided in the orificial slit to impart a change of direction to the flow of processing gas. Each guide vane is a spatial body with differently extending, vertical limitation surfaces, which between adjacent vanes delimit ducts whose sectional area as measured transversely of the flow direction of the processing gas through the individual duct is substantially of the same size over the extent of the duct. The vertical height of the guide vanes may decrease along their radial extent inwards in the orificial slit, and their vertical limitation surfaces may form an acute angle at the radially innermost ends of the guide vanes.

Abstract: A suction film holder for a reproduction camera is formed by a flexible cover in the form of a conveyor band. One or more suction cups and a plurality of transverse grooves are provided in connection with the flexible cover. During the exposure of a sheet of light-sensitive material the transverse grooves tightly abut longitudinal grooves along the rim of an underlying glass plate, the grooves in the glass plate being connectable to an evacuation system.According to a particularly preferred embodiment air is blown inwards below the flexible cover upon the exposure. In this manner the time for loosening the flexible cover from the underlying glass plate is reduced to 5-10 secs. The blowing in occurs automatically when the vacuum is removed by means of an inflatable membrane in a box situated parallel to a pressurized valve communicating with the vacuum pump. The membrane is thereby blown up by means of vacuum and blows automatically the air inwards below the flexible cover when the vacuum is removed.

Abstract: A plurality of resilient wires interconnected at their respective ends form a collapsible filter basket adapted to be introduced into a blood vessel of a patient. The basket in its expanded and relaxed state forms an apertured, elongate solid of revolution with pointed ends and has a base as measured between the pointed ends at least equal to the maximum diameter thereof. The design of the filter basket of the present invention facilitates insertion and adjustment of position or orientation once inserted and allows large masses of emboli to build up without seriously restricting the free area available for blood flow through the filter.

Abstract: The measurement of large DC and AC currents, are measured by a zero-flux current transformer. Two identically wound toroidal cores in which the magnetic flux induced by a primary current is neutralized by a counter-flux induced by a compensation current is passed through a compensation winding (14) common to both cores and having many turns. The compensation current is adjusted by means of an amplifier so that the mean flux in the cores is zero. The intensity of the compensation current is measured by the voltage drop across a measuring resistor.

Abstract: The invention relates to a valve for volatile liquids such as an expansion valve for a refrigeration plant. Magnetic valves of this type have a plunger actuated closure member which controls a small throttle opening which functions to vaporize the cooling liquid. The valve action can be noisy and damping chambers have been provided for damping the movement of the plunger. As disclosed herein such a damping chamber is disposed in the flow path downstream from the throttle opening where a cooling vaporization occurs and the cooling vaporization is effective to minimize vaporization in the damping chamber which would otherwise reduce the effectiveness of the damping chamber.
