  • Patent number: 4973026
    Abstract: An 2-way on/off high pressure water jet cutting valve is provided with a valve stem designed to close under the influence of high pressure inlet water, an a hydraulic piston designed to open the valve stem against the force exerted by high pressure inlet water. The valve stem extends through the hydraulic piston. The valve stem and the hydraulic piston are contained within the valve housing. Externally applied forces are not required to operate the valve or to insure that the valve operates properly under the influence of the various fluid pressures that are applied to it.

  • Patent number: 4966401
    Abstract: The present invention provides a truck frame-mounted tool box glide system that can carry a hinged-lid type tool box. The glide system can store the tool box out of the way beneath a truck flat bed. The system permits the tool box to be pulled laterally out from the side of the truck until the box lid is completely exposed so that the lid can be swung upward to fully expose the box interior. Such a system permits full utilization of the tool box interior, even for heavy objects that can be lifted vertically into and out of the box. The system may provide for dual tool box mountings, where one tool box is mounted to each side of the truck.

  • Patent number: 4949884
    Abstract: A paint can lid comprising a one-piece molded plastic lid. The periphery of the lid is formed to provide an outer edge that will engage the underside of a paint can rim, engage and extend up along the outer, vertical edge of the paint can rim, and extend inwardly along the top of the paint can rim. Inward of the lid periphery, the lid is formed with a downwardly-extending annular cavity defined by the lid wall having a U-shaped cross section. Immediately inward of the annular cavity, the lid is formed to provide a pouring spout of frusto-conical configuration having a truncated top. The top of the spout is provided with a peripheral rim enclosing a pouring opening of a diameter smaller than the diameter of the spout top itself.

  • Patent number: 4909059
    Abstract: A metal tubing bender forms arcs into metal tubing by engaging a swing-arm mounted roller against a clamped tubing section and rotating the roller through an arc necessary to place the desired degrees of bend into the tubing. The tubing is clamped against a forming plate that is provided with a peripheral groove of uniform radius and serves as a die for the forming operation. The forming plate stands out from a mounting plate and the roller swing arm fits between the mounting plate and the forming plate for stability of operation.

  • Patent number: 4848671
    Abstract: A high pressure water/abrasive jet cutting nozzle has a pair of centering rings that act through body-mounted balls to position a nozzle element-holding collet. The interior surfaces of the centering rings are eccentric with respect to the longitudinal axis of the nozzle assembly so that rotation of a centering ring will cause the nozzle element collet to shift transversely. By rotating one or the other, or both, centering rings the axis of the nozzle element can be adjusted relative to the nozzle jet-forming element so as to align the nozzle element with the water jet.

  • Patent number: 4828875
    Abstract: Sintered films of Cd.sub.1-x Zn.sub.x S (0.ltoreq.x<1) with high optical transmittance are provided. These films are produced by applying a paste composed of powdered CdS and CdCl.sub.2 or of a mixture of CdS, ZnS and CdCl.sub.2 onto an appropriate substrate such as borosilicate glass, under an inert gas atmosphere containing ZnCl.sub.2 vapor or thereafter resintering the paste on the substrate under a nitrogen atmosphere.The ZnCl.sub.2 vapor is produced by heating ZnCl.sub.2 at 400.degree. C. or higher but below the temperature of 500.degree.-700.degree. C. to which the specimen is heated.The resulting sintered films have optical transmittance of 80% at long wavelength ranges or higher and can be used as a window layer having a superior optical transmittance in solar cells.

  • Patent number: 4778285
    Abstract: An external lubricant reservoir of the type that is replenished by injection is provided in the form of a flexible membrane sealed to a lubricant distributor. The lubricant distributor consists of a membrane-mounting disk and a lubricant feed tube. The feed tube communicates with the reservoir interior through a passage in the disk. The feed tube is designed to be inserted into a lubricant passage in the housing of a joint or a bearing. A preferred embodiment of the reservoir enables the membrane to be wedged between a joint or bearing housing and the underside of the membrane-mounting disk to effect a sealed connection between the two.

  • Patent number: 4775082
    Abstract: A catch bag has a flat lid of resilient material which is hinged to a frame around the opening of the bag. A diametrical slit in the lid allows easy insertion of articles, such as speared fish, with one hand while the lid retains articles securely inside the bag. When access to the contents of the bag is desired, the hinged lid facilitates emptying of the bag. An elastic wrist cord opposite the hinge can be used to keep the bag near at hand while leaving the user's hand free, and also to hold the hinged lid shut. A carrying handle is attached along a side of the bag for convenient transporting of the bag on dry land.

  • Patent number: 4739236
    Abstract: There is disclosed a portable system to control and monitor the basic maneuvering functions of marine vessels: The control and monitoring functions are contained on a hand held, small and lightweight consul which can be plugged into multi-pin sockets which are wired from various remote places of the ship to a central electronics logic and control module matrix. Switches on the portable helm control the electronic module matrix which powers servo motors mechanically linked to: engines' throttle controls, shift forward-neutral-reverse controls, and steering apparatus. Feedback loops monitor the positions of these maneuvering functions. Monitored on the portable helm are: rudder angle, engines' idle status, forward, neutral and reverse status of each drive trian, power on, and engines' synchronization.
