Abstract: A trim piece for installing at a drywall external right angle corner which is provided with a bullnose corner bead includes an intermediate portion which wraps over the convexly curved portion of the bullnose corner bead and has two edges extending parallel to the edges of the flanges of the corner bead. Two leaves are attached to the intermediate portion of the trim piece at the two edges respectively. The intermediate portion of the trim piece has an interior surface at a first end matching closely the exterior surface of the corner bead and an exterior surface which is convexly curved at the first end and is right-angled at the opposite second end and provides a transition from the convex curve to the right angle between the first and second ends.

Abstract: Two playing pieces each include a body portion, a shield having at least two hinged segments attached to the body portion, a first control mechanism operable to select one of the hinged segments as a blocked segment, a projecting element attached to the body portion and having a raised position and at least two lowered positions, and a second control mechanism operable to select one of the lowered positions as an active position. The two playing pieces can be placed on a track structure at opposite respective ends for movement towards each other along respective paths of movement. In one possible outcome, the projecting element of one of the playing pieces strikes the blocked segment of the shield of the other playing piece and in another outcome the projecting element strikes an unblocked segment of the shield of the other playing piece.

An adaptor plate is attached to a Z axis abutment structure and has a surface at a predetermined Z axis position relative to the receptacle surface of the load board, the surface of the adaptor plate being presented toward the handler location. At least three spacers are attached to the adaptor plate and project from the surface of the adaptor plate.

Abstract: A semiconductor device, such as a back side illuminated CCD, is fabricated by forming an insulating layer over the front side of a body of semiconductor material, depositing a layer of high resistivity material over the front side of the insulating layer, patterning a portion of the layer of high resistivity material to form a long and narrow trace, and attaching a support member to the front side of the insulating layer. In the case of a back side illuminated CCD, the patterning of the layer of high resistivity material advantageously forms a long and narrow trace substantially confined to a peripheral area of the front side of the insulating layer and the semiconductor material is removed from the corresponding peripheral area of the back side of the insulating layer, leaving a plateau of semiconductor material that does not extend over the area that contains the long and narrow trace.

Abstract: Apparatus for real time measurement of optical beam parameters includes an assembly of known dimensions, carrying multiple apertures, occupying parallel planes. The assembly can be moved so that the apertures sequentially intersect an optical beam which is not propagated in the plane of the apertures. At least one pair of the apertures are non-circular and identical with accurately established positions and which are not disposed in the same angular alignment when they intercept the beam but are disposed in the same plane in order to allow determination of the two-dimensional position of the centroid of the beam in that plane.

The follower unit includes a follower element which is turnable in the follower unit about an operating axis and is accessible from at least one side of the door for turning by means of a key operated locking mechanism. Force transmitting elements provide a force transmitting connection between the follower element and the bolt of the lock casing.

Abstract: A transparency embodying left and right stereoscopic images of a selected scene, positioned to provide a 3D image of the selected scene when viewed using a 3D viewing device, is made by creating first and second image data files representing the left and right stereoscopic images respectively of the selected scene, employing the first and second image data files to create a stereo image data file representing the left and right stereoscopic images in predetermined relative positions, and employing the stereo image data file to create a transparency image incorporating the left and right stereoscopic images.

Abstract: An electrical parameter of a rod-form conductive element is measured using a measurement fixture which includes an insulating support on which a first conductive element is mounted. A transmission line connector mounted on the insulating support and has a signal conductor connected to a first conductive element mounted on the support member. A holder for removably receiving the rod-form element includes a conductive member which is in electrically conductive contact with the rod-form element when the latter is positioned in the holder. The holder is mounted relative to the support member by a mounting structure such that when the rod-form element is positioned in the holder, an end of the rod-form element can be brought into electrically conductive contact with the first conductive element.

Abstract: A raster scan digital signal acquisition and waveform display instrument displays a dot representing a signal event with a color parameter in accordance with the value of a corresponding data word stored in a raster scan memory. A user interface control element supplies a single color parameter control value from which multiple independent control values for influencing the values of the data words stored in the raster scan memory in response to the single color parameter control value are generated.

Abstract: A sewer system includes a disposal system under atmospheric pressure, a sanitary unit provided with a water trap, and a branch sewer pipe connecting the sanitary unit to the disposal system. A vacuum generator is connected to the branch sewer pipe for generating underpressure in the branch sewer pipe.
