Abstract: A paving stone for the surface covering of areas, paths or the like in a composite structure has a middle body part possessing a plane top side, an underside parallel to the top side and four lateral end faces. On two mutually adjacent end faces of the body part there are respective upper extensions, of which the first upper extension extends over the entire respective end face and the other, second upper extension extends over the entire respective end face and the width of the upper extension. The top side of the upper extension is in each case in line with the top side of the body part, their end faces are essentially vertical, and an elevation parallel to the respective end face and to the top side is present on their respective underside. On the other two end faces of the body part there are respective lower extensions which extend at least over the respective end face of the body part and of which the underside is in line with the underside of the body part and the end face is essentially vertical and on the top side of which a groove parallel to the respective end face and to the opposite elevation is provided for the positive reception of an elevation of an adjacent paving stone. The elevation of each upper extension terminates at a distance from the end face of the other upper extension transverse relative to it which is at least equal to the width of the other upper extension. The inner flank of an elevation facing the body part is at the same distance from the side face of the body part adjacent to it as the outer flank of a groove from the side face, adjacent to it, of the respective upper extension having the groove. <IMAGE>

Abstract: An automated system is used for the inspection of a transparent film which has been metallized by vaporizing a metal so that it impacts the film's surface at a preselected angle, wherein the metallized film sample is illuminated with a light source, end the transmitted light is passed through a microscope to a video camera, which produces a videoscan. The videoscan is digitized, stored in a computer memory, and processed pixel by pixel by the computer which calculates asperity height distribution from the number and lengths of metallizing shadows caused by asperities on the film surface. This method is especially useful for inspecting film to be used for recording devices, especially for video tapes, where accurate information on the asperity height distribution is required.

Abstract: Centrifugation apparatus comprising a sample chamber, a deposit-receiving surface such as a slide (3) and a filter card (1) having an aperture (4) adapted to define on that surface a deposition area communicating with the sample chamber is characterised by the feature that liquid flow paths in the filter card from the perimeter of the aperture (4) are selectively restricted in cross section so as to promote constant velocity flow of liquid, from the sample chamber into the card, in directions substantially normal to all points on the periphery ofthe aperture. This promotes uniform deposition of solids on the deposit-receiving surface throughout the deposition area, to facilitate inspection of the deposit and, particularly, automated optical scanning of the deposit. The cross sectional restrictions may be accomplished by local removal of filter card material; by local compression of the filter card: or by local impregnation of the card material with an occlusive agent.

Abstract: An optical lens carrying support structure for use with a protective face mask, comprising a pair of lens frames (1), each frame comprising an eyewire (2) and a hinge portion (4), the lens frames being connected by a hinged nosepiece (3, 5). The support structure attaches to the face mask by a slideably releasable dove-tail connection (27, 29) to a trapezoidal back-block (25), which back-block rigidly attaches to the face mask, with two opposite faces of the trapezoidal back-block inclined with respect to each other so as to establish the proper pantoscopic angle. The face-form angle is accomplished by virtue of an angled relation of the eyewire (2) to the hinge portion (4) of the lens frame (1). The lens frames (1) fold back toward each other, facilitating removal of the lenses and folding the face mask assembly flat making it easy to remove the lens (107) by snapping it out of the eyewire (2).

Abstract: The specification describes a new and improved thermal ink jet printhead and fabrication process therefor wherein the heater resistors are formed on one area of an insulating substrate and relative large area electrical contacts are formed on an adjacent area of the insulating substrate. A barrier layer is formed over the conductive trace pattern defining the heater resistors on the one area, and a small via in this layer provides an electrical path between the large area electrical contacts and the conductive trace pattern, and thus provides a current drive path for the heater resistors. The small via provides minimum exposure of the barrier sidewall area and area of the conductive trace pattern and thus improves device reliability and fabrication yields and also improves electrical contact to the printhead. 
     Alternatively, the barrier layer may be made less than laterally coextensive with the conductive trace material to thereby leave a small area of the trace material available for metal overlay connection to the large area contact pad which is formed to the side of the conductive trace material.

The said components are compared with those of a reference system similar to the above system but without the specific ligand. Any reduction in the capacitance or variation in the resistance in comparison with those of the reference system indicates the presence of the said biological substance in the liquid medium concerned.

Abstract: A method and a device for the control of a joint between a first element (18) and a second element (21). The first element preferably is an end element of a container and is inserted in an opening in said container such that a rim is formed around the opening and includes a joint (16). 
     The rim allows the placement of a radiation or wave energy transmitting source (13) at one side thereof and a detector device at the other side. The radiation or wave energy source has a capacity of penetrating, preferably fully, the rim and illuminating said rim by a small dot (14), which is scanned crosswise the width of the joint by a scanner device. 
     The container (10) is rotated around an axis (12) and the de­tector device (22) registers the characteristics of the radia­tion that passes the joint and/or is reflected at the joint and which originates from a repeated "point illumination of the joint". By placing the detector device at a sufficient distance from the rim there is obtained a magnifying effect in the de­tector, which allows the detection of very small changes in the quality of the joint. 
     The method and the device are especially suited for joints comprising substantially plastics material and where the pro­duct, which may affect the joint also substantially consists of an organic material, for instance a food product.
