  • Patent number: 4751751
    Abstract: A disposable urinating funnel for females comprises a thin, paper-like sheet which is folded in half to form two overlapping sections whose free edges are connected together and are tapered toward the fold line to form a funnel-like shape. The upper edges of the funnel-shape are curved to cover a female vaginal area, and the opposite, bottom edges form a spout-like portion. Score lines are formed midway between the fold line and connected side edges in each of the sections and extend upwardly from the bottom of the spout-forming portion toward the upper end of the funnel-like shape. Manually squeezing the fold line and connected side edges toward each other causes the otherwise flat funnel-like shape to open, by bowing the sections apart along the score lines. In addition, the tapered, connected-together edges are cut along a shallow curve which permits the funnel to be used with the fold line forwardly or rearwardly for selectively directing the flow of liquid through it.

  • Patent number: 4751753
    Abstract: A portable toilet enclosure comprises a base and sidewalls attached to sides of the base. The base has a wall in which a portable toilet is disposed. A moveable wall is supported on the sidewalls and is operable to a closed position in which the portable toilet is concealed from view and to an open position which provides use of the portable toilet in the usual manner. The sidewalls incorporate integral hand grips along the top. The bottom edges of the sidewalls provide support for the enclosure on an underlying surface. A pair of wheels are mounted at the lower front corners of the enclosure. With the toilet resting on its sidewalls, the wheels are slightly out of contact with the underlying surface. Forward tipping of the enclosure brings the wheels into contact with the underlying surface while at the same time elevating the lower edges of the sidewalls from the underlying surface so that the enclosure can be rolled.

  • Patent number: 4751754
    Abstract: A hydraulically operated hospital bed with dual hydraulic power systems for operation with or without electrical service. The bed has its head and thigh/leg elevation functions performed by hydraulic cylinders. A control circuit meters the introduction and removal of hydraulic fluid from these cylinders so an occupant of the bed is not subjected to any sudden movement. In case of an emergency requiring the bed occupant to be in a supine position (the need to perform CPR), the normal control circuit is bypassed by an emergency circuit that allows much faster than normal lowering of the head and thigh/leg portions of the bed.

  • Patent number: 4751759
    Abstract: The appliance is intended to remove dust from solid objects and comprises an ionization device (7) which is operatively associated with an incorporated air nozzle (1), which has an obliquely arranged, narrow, linear blowing slot (2) which serves to produce an air jet which sweeps over the surface to be cleaned at high velocity. The ionization device (7) produces positive as well as negative ions in the laminar air jet in order to neutralize the electrostatically-charged dust particles. An air suction nozzle (3) with a corresponding suction slot (4) is arranged at a short distance from the blowing slot (2) and is operatively associated with a flat brush (5) projecting from the appliance, which serves as a baffle, determining the distance of the appliance from the surface to be cleaned, limiting the gap enclosing the laminar air jet and, to a large extent preventing sucking-in of the surrounding air. This arrangement is designed as a portable and industrial cleaning appliance.
