Abstract: An apparatus for sticking onto a screen plate a photosensitive laminated film obtained by forming a layer of a photosensitive agent on one surface of a base film, wherein a blade is provided on the front side of rollers that hold the photosensitive laminated film to press-adhere said photosensitive laminated film onto the screen plate. The tip of the blade presses the photosensitive laminated film onto the screen plate such that an angle is defined between the photosensitive laminated film and the screen plate to get rid of the air. Therefore, no bubbles are trapped therebetween.

Abstract: A process is provided to graft functional moieties to base polymers by contacting the base polymer with functional group containing diazo compounds. The preferred function group containing diazo is ethyl diazoacetate. The base polymer is a copolymer or polymer having monomer units of alpha olefins, conjugated diolefins, vinyl aromatics, or hydrogenated conjugated diolefins. The process is performed in a melt and results in low levels of scissioning, coupling and degradation.

Abstract: A transgenic avian line, which is resistant to infection by avian leukosis virus (ALV), subgroup A, has been produced. The line was discovered as a chance event occurring in a program of infecting embryonic chickens with a recombinant ALV virus, selecting individuals assayed to be positive for genomic insertion of proviral sequences, and backcrossing to the original line to obtain G1 progeny demonstrating stable inheritance of the inserts. Of at least three proviral inserts defective for ALV production, one was found to be capable of expressing in the cell membrane subgroup A envelope glycoprotein which specifically interferes with infection by subgroup A virus. This insert represents an artificially introduced dominant gene for ALV disease resistance. Through an appropriate breeding program, a line of chickens homozygous for this gene has been obtained.

Abstract: The Airborne Infrared Transmissometer measures the infrared transmission between a test target aircraft and a detection system. A transmitter is attached to an aircraft and emits a calibrated infrared beam. A ground-based, shipborne, or airborne receiver measures the transmitted signals in the exact same path between the target aircraft and the detection system. Data recording equipment can be attached to both the transmitter and receiver to measure the associated outputs.

Abstract: Poinsettia `441` is a stiff-stemmed, early flowering cultivar with dark red flower bracts. It has dark green, medium size foliage and a strong branching habit. The plant height is medium and some chemical growth retardants may be needed to control the height of flowering plants. The appearance and cultural requirements are very similar to Poinsettia `Lilo` (U.S. Plant Pat. No. 6,694). However, stronger self-branching traits and better post-production keeping qualities make `441` a more desirable commercial cultivar than `Lilo`.

Abstract: The present device provides a downstream magnetic shield which is integrally formed with a write pole section having a tip to make up a magnetic recording head. The shield and the write pole tip are located with small gap therebetween, so that magnetic flux which fringes from the magnetic write pole tip is intercepted by the shield. Accordingly such fringing flux does not pass through the recording medium, and hence if a data bit has been written into the recording medium its dipole identity will not be weakened by the fringing flux of a subsequent data bit being written into the magnetic recording medium. In addition, the magnetic recording medium is made up of a first layer of material having perpendicular uniaxial anisotropy and an underlying layer made of a material which has a low magnetic flux reluctance characteristic.

Abstract: An improved toilet flapper valve (10) designed to directly replace either a conventional toilet flapper valve or tank ball valve. The valve (10) allows a toilet user to selectively determine the quantity of water used for a toilet flush by controlling the time that a toilet flush handle (38) is held in the depressed position. The water quantity used depends on whether liquid or solid waste is to be flushed. For liquid waste, a partial flush is used; for solid waste a full flush is recommended. The valve (10) consists of a resilient body having a cavity (12) located over the toilet tank drain (34). The cavity houses a weight (16) that fulfills two functions: it provides the weight necessary to make the valve non-buoyant and it produces under the area of the weight, a flat rigid section (18) that extends radially over and beyond the perimeter of the valve seat (36). This rigid section provides a positive seal without sagging which can produce unnoticed leaks.

Abstract: A take-apart drive-over bridge with cantilevers between the drive-overs. The two sections of drive-over (4) associated with each section of the bridge constitute, along with the section of cantilever (5) between them, a transport unit and are simultaneously secured to the corresponding drive-over and cantilever sections of the adjacent bridge section by the bridge-laying system, which consists essentially of a vehicle (1), a latticework outrigger (2), a main boom (3.1), and an auxiliary boom (3.2), while the bridge is being assembled. The two sections of drive-over associated with each bridge section and the section of cantilever, which is in two halves, slide together for transport and apart for assembly.The two drive-overs and the cantilever have U-shaped latticework structural sections with uprights (11 or 16) and horizontals (12 or 19) at the top.The horizontals (19) and beams (15) are removable.

Abstract: A hydraulic lift bridge/leveler that is raised by an hydraulic cylinder and lowered primarily by gravity. A toggle mechanism is used to lock the bridge in a near vertical position. An auxiliary cylinder moves a lock-out arm assembly to release the toggle mechanism and power the bridge downward to a point where the weight moment through the pivot point is significantly large that the bridge will lower itself by gravity. The main cylinder employs a cushion mechanism that decelerates the bridge by slowly increasing hydraulic pressure in the cylinder. This allows the bridge to be raised at an initially high rate of speed and then slowed down near the end of travel at a near vertical position.

Abstract: A paint applicator comprises a frame with a flat side which carries an absorbent pad; the other side of the frame supports a handle. The axles for a pair of rollers depend from a hinged mount supported on the handled face of said frame; the axles are parallel and are inclined toward one margin of the frame. The angle of the hinged mount with respect to the frame is adjustable. The rolling face of each of the rollers have a circumferential groove and the edge of the rolling distal from the frame has a circumferential flat surface which converges toward the axle of the roller in a direction away from the frame. The applicator may be used to edge the paint on a surface adjacent a narrow moulding with a bevelled corner by positioning the applicator so that the pad is against the edge of the surface with the grooved rolling face cupping the bevelled edge of the moulding. The incline of the rollers may need to be adjusted to achieve this.
