Abstract: An impatiens plant which is a derivative of the variety known as "Duet" found as a sport in a planting of the variety "Dapper Dan" (U.S. Plant Pat. No. 7,130) where the double deep red flowers are contrasted with foliage which is the usual green of the impatiens leaves, having a variegated border in which the leaf variegation pattern is not uniform in at least two mesophyll layers of leaf tissue rendering the appearance as being layered, the color being of yellowish white and as a border of varying widths. The leaves appear to be substantially the same shape as the variety "Dapper Dan". The overall color of the flowers is noticeable as being substantially more orange than that variety, when the flowers are compared with those of U.S. Plant Pat. No. 7,130.

Abstract: A valve plug (22, 22a, 22b) is biased inwardly by a spring (78, 78a, 78b) to close an opening (6, 6a, 6b) in a tank. A stem (32, 32a, 32b) extends axially inwardly from the plug (22, 22a, 22b). The stem (32, 32a, 32b) has an inner portion (36, 36a, 36b) which is mechanically interlocked with an outer portion (52, 52a, 52b) to directly transmit axial forces created by the spring (78, 78a, 78b). Fusible material (66, 66a, 66b) holds the stem portions (36, 36a, 36b, 52, 52a, 52b) in an interlocking position but carries only relatively small loads. The plug (22, 22a, 22b) and stem (32, 32a, 32b) move against the force of the spring (78, 78a, 78b) to relieve pressure. At elevated temperatures, the fusible material (66, 66a, 66b) melts to allow the stem portions (36, 36a, 36b, 52, 52a, 52b) to separate and the plug (22, 22a, 22b) and outer stem portion (52, 52a, 52b) to move away from the opening (6, 6a, 6b).

Abstract: An embedded framing bit pattern in a serial bit stream is located by combining the last bit to arrive of the serial bit stream with a predetermined number of prior bits of the serial bit stream which are spaced apart by the pitch of the bits of the framing bit pattern, and this combination of the bits is tested to determine if the combination matches part of the framing bit pattern. If a match does not occur, then the bits which were combined together are changed to a bit pattern that will not result in a match when these bits (except for the eldest bit which is disregarded) is combined again with a new bit of the serial bit stream, no matter what the logic state of the new bit. In this manner all of the bits, as they arrive and are combined and tested, will eventually be changed except the bits which are part of the framing bit pattern.

Abstract: A dual flush toilet control mechanism includes an operating handle and attached actuating cam, a control arm and a control float arm. When the handle is turned in a first direction, the actuating cam moves the control arm to open fully a conventional toilet tank main valve to its buoyant position. When turned the handle is turned in a second direction, the actuating cam moves the control arm to open partially the main valve to a position wherein it is subject to the suction developed by the water exiting the toilet tank. A control cam on the control float arm maintains the control arm in position to maintain the main valve open against the suction until the water level in the tank drops below a predetermined level. When the float on the control float arm reaches the predetermined water level, the attached control cam allows the control arm to drop and the main valve to close.

Abstract: A specially designed and attached anti-wind lift airfoil also acts to reduce wiper chatter in several ways. The foil is fixed to and runs along side the blade support, bracing and stiffening it. In addition, masses molded inside the foil, plus its own mass, increase the total mass and moment of inertia of the wiper in operation, which acts to counteract the sticking effect. The foil is somewhat resilient, and is fixed to the blade support at widely spaced points, with its center section unsupported. If the blade does stick and slip in operation, undulations are thereby set up in the resilient airfoil, absorbing and damping out the energy that would otherwise show up as chatter.

Abstract: A two-part, hand-held portable cleaning system provides the ability for washing and vacuum cleaning printing stencil screens and the like in-situ in an environmentally safe manner. The system includes a vacuum-assisted drip pan and an applicator brush with a specially designed low-pressure, solvent-dispensing nozzle. The drip pan is held beneath the stencil or screen while the applicator brush floods the area to be cleaned with solvent, thus dislodging the accumulated printing medium by the mechanical action of the brush. Much of the contaminated solvent flows through the stencil or screen into the drip pan below. Vacuum hoses attached to both the drip pan and the applicator brush remove the liquid solvent and any solvent vapor in the vicinity. A separation chamber is located in the air vacuum circuit between the blower and the hoses and is positioned above the reservoir connected thereto by a gravity-feed drain line.

Abstract: A door closer has a fluid conduit connecting the high pressure portion of the cylinder in front of the piston with a cavity between the surfaces of the cylinder wall and the piston. This cavity is located at the intermediate lateral surface of the piston at the back side of a gear rack formed on the piston. The variable lateral bias provided by the pressurized cavity counteracts separating forces between the gear rack and a gear pinion caused by the tapered teeth. This decreases friction between the piston and the cylinder and reduces wear throughout the closer mechanism.

Abstract: This invention, which provides a solution to the long-standing problem of motion-related rattle in torsion balances for windows, is based upon the discovery that the major source of the rattle is related to the movement of the free end of the twisted rod that is mounted within the coil of the torsion spring. A sound-deadening element of resin material is secured to the free end of the twisted rod, being positioned proximate to the extremity of the free end, and the preferred element has a maximum dimension (measured radial to the spring) that is greater than the maximum cross-sectional dimension of the twisted rod but less than the effective internal diameter of the coiled spring. The sound-deadening element eliminates the rattle by preventing contact between the free end of the rod and the spring, and it also acts as a glide to facilitate relative movement between the rod and the spring during operation of the balance.

Therefore the shedding procedure will be continuously performed without cutting the warping yarns for each band. After the warping procedure, the lease cords are passed through the holes on the heddle hooks at the leading ends of the lease tapes.

Abstract: Apparatus for attaching and bi-directionally tensioning a porous fabric over a flexible, rectangular form support. A frame comprises a pair of rigid, parallel frame members connected by a pair of parallel cross members. The ends of the frame members contain legs that contact the form support in each corner thereof. Suction cups located on the cross members allow the form support to be attached to the frame and pulled towards the frame such that the edges of the form support flex between adjacent legs. Once the form support has been flexed, the porous fabric is wrapped over and attached to the form support at the corners and along all sides. After the porous fabric is completely attached to the form support, the frame is removed so the form support can return to its flat unflexed, rectangular dimensions. The result is that the porous fabric is bi-directionally stretched over the form support such that a uniform tension of 50 to 300 kg/lineal meter is created.

Abstract: A tool for cutting tubing or light pipe provides conventional cutting rollers and a blade in combination with a spring loaded, open jaw clamp. The open jaw permits the tool to be passed over the side of the material to be cut, while the spring compressive force automatically urges the cutting blade into the material being cut as the tool is rotated around the material in the manner of conventional tubing and pipe cutters. Thus, the need to continually adjust the cutting blade as the cut deepens is eliminated. Two basic embodiments are disclosed, one comprising a handled clamp type tool with or without foldable or extendible handles, and the other comprising a C clamp type tool. The spring loading arrangement of the cutting blade is common to both. Various versions and improvements are also disclosed, including mechanisms providing for parallel actuation of the cutting assembly, proper spacing of the cutting rollers, and maintaining the proper angular relationship between the rollers and the cutting blade.
