  • Patent number: 5294089
    Abstract: A proportional flow valve wherein inlet fluid pressure urges the valve member toward the valve seat. A pressure member, which may be a piston, has an effective area substantially larger than that of the valve member, and is also selectively subjected to inlet fluid pressure to urge the valve member away from the valve seat, so as to open the valve and keep it open. A solenoid actuator determines the position of a pilot valve member which controls the flow of inlet fluid to the pressure member, and hence controls the location of the pressure member and the spacing of the valve member from the valve seat. The position of the pilot valve member, and hence the spacing of the valve member from the valve seat, is proportional to the amount of electric current applied to the actuator.

  • Patent number: 5168779
    Abstract: An opener for a videotape cassette case of the type having a body and a cover hinged to the body, the body and cover presenting two parallel spaced-apart flanges when the case is closed. The opener includes a rigid element, which may be a flat plate, having a shoulder portion wider than the spacing between the case flanges when the case is closed, the shoulder portion tapering toward a nose portion which is narrower than the spacing between the case flanges when the case is closed. A closed videotape cassette case is opened by inserting the nose portion of the opener into one end of the space between the flanges and moving the case with respect to the opener so as to bring the shoulder portion between the flanges to urge the flanges apart. Continued movement of the case with respect to the shoulder portion of the opener causes the flanges to progressively separate from each other so as to pry the cover from the body and thereby open the case.

  • Patent number: 5161798
    Abstract: A toy ball having a soild body of foam plastic material and a noisemaker completely embedded within the foam plastic body. The noise maker includes a hollow rigid housing, which may be formed of a hard plastic, and a marble within the housing free to roll around therein so as to create a clattering sound when the ball is shaken, thrown, and caught. The internal surface of the housing has inwardly-projecting ridges to enhance the clatter produced as the marble, which may be a steel ball, rolls around within the housing. The foam plastic body of the ball is made in a mold cavity having the shape of the ball to be produced. While the mold is open, the noisemaker is resiliently suspended along the centerline of the mold cavity so that the center of the noisemaker substantially coincides with the midpoint of the mold cavity centerline. Plastic material is placed within the mold cavity, the mold is closed, and the plastic foam expands to fill the mold cavity, at the same time completely surrounding the noisemaker.

  • Patent number: 5160817
    Abstract: An electrical switch contact arrangement having a spring which snaps the movable arcing contact away from the stationary arcing contact at a high rate of speed to open the arcing contacts, but only after the movable main contact has moved through a considerable portion, for example, at least about 50%, of its opening movement away from the stationary main contact. The spring is tensioned as the main contacts open. At an intermediate point during the opening movement of the movable main contact, the moveable main contact positively initiates opening movement of the arcing contacts whereupon the spring snaps the arcing contacts open at a high rate of speed independent of the opening speed of the main contacts.

  • Patent number: 5146865
    Abstract: A water-jet propulsion system for ships, which are intended to be used in shallow waters. A semi-axial, bladed turbine wheel with a vertical axis of rotation is disposed so that it can rotate in a well-shaped pressure housing. Into the pressure housing, the driving mechanism for the turbine wheel is introduced from above through a cover plate. At the lower end, the pressure housing is closed off by a bottom plate, which has a concentric, centrally disposed water inlet for axial flow against the turbine wheel and at least one water outlet with a shallow inclination. A guiding apparatus in which the flow energy of the water conveyed by the turbine wheel is largely converted into pressure energy is disposed between the outlet end of the conveying channels of the turbine wheel and the at least one water outlet.

  • Patent number: 5118401
    Abstract: Apparatus for applying a disinfectant solution which may include hydrogen peroxide, a salt and a buffer to an instrument wherein the instrument can be inserted into an opening in the wall of a vessel containing a disinfectant normally at a level below the opening. A floatation plunger is urged downwardly to displace the disinfectant to a level in engagement with the instrument and the electrodes are energized to activate the disinfectant. A magnetic latch holds the floatation plunger in place during disinfection and the disinfectant level is sensed to enable energization of the electrodes only when the level is sufficient to engage the instrument.
