Abstract: A water ski vest is formed of EVA cross-linked polyethylene. The vest fits around the torso or over the shoulders of the wearer and is held in place by belts which extend around the vest. The belts extend through indented loops formed in the polyethylene material to prevent the belts from contacting the wearer's skin. Loops riveted or sewn onto the male ends of the belts extend through the loops in the vest to transmit stress directly to the belts instead of the foam material. The surfaces of the foam material are provided with a fine mesh texturing to give the material a cloth-like feel and appearance. Creasing patterns formed in the shoulder portions and in the back and side portions provide flexibility. The shoulder material is tapered in thickness to reduce bulk and the upper portion of the back is tapered in thickness to minimize catching water in a hard fall. The outer perimeter edges of the vest are rounded to enhance comfort and appearance.

Abstract: A personal flotation apparatus is made of one or more layers of cross-linked polyethylene polymeric foam material. A nylon or polyester cloth preferably having a tight weave is fused to one or both of the inner or outer surfaces. When more than one layer is used the cloth may be fused to interfaces of both layers. Edge portions of the personal flotation apparatus are rounded inward and cloth fused to the outer surface is extended inward around the round edge to abut or overlap and be joined to cloth on an inner surface.

Abstract: A linear bearing is made with races molded in place in a plastic shell. An inner ball cage is assembled by sliding the cage into the shell.

Abstract: Services, such as electricity and water, are supplied through conduits to moving machinery such as a longwall mining machine which moves along a conveyor or other fixed path. A channel having an open mouth which is flexibly sealed is disposed alongside the path and contains supply conduits for the machine. A sleeve projects through the channel seals into the body of the channel and guides the conduits to the machine. A gas may be fed to the machine via the channel and sleeve. As the machine moves the conduits bend over themselves.

Abstract: A valve device to control fluid through a passageway under a pressure head which may vary, has at least one vane which lies in the passageway to restrict the fluid flow. The vane is effectively flexible and resilient to deflect under fluid flow and so increase its restricting effect on increase in the pressure head and decrease its restricting effect on decrease in the pressure head so as to maintain a substantially constant flow output through the passageway.The valve device may be incorporated in a nozzle for insertion as one of a series along the length of an irrigation pipe, and the nozzle may be provided with a pointed head part and an outlet tube or cap.The device also has application in other forms of fluid control.

Abstract: The present invention relates to an apparatus for suctioning and collecting flotage on the water surface. The apparatus consists of a water guide passage to collect surface flotage, a guide plate floating below the water surface in said water guide passage, a rearward facing means to eject a pressurized water current, and an additional means similarly ejecting a pressurized water current to check and suppress currents which hinder the effect of the water flowing in said water guide passage.

Abstract: For improved vibration damping are used preferably a plurality of parallel bodies (30) of generally thread-like configuration which are embedded in a layer of adherent viscoelastic material (29) applied to a vibrating structure or to a body (24) which in turn rests against a vibrating structure (22).

Abstract: A mast step is mounted on a traveler having two parallel linear bearings which ride in lateral grooves on a central track. The central track has downward enlarged vertical holes on 2-inch centers which hold detent balls. The detent balls are locked in their upper active position with a contact and lock the traveler in a preselected position. Depressing an operator pedal moves a slider bar within the track to align detent receivers with the openings in the track. As the detent balls drop into the receivers in the slider bar, the platform is released to move toward a new location. When the pedal is released, a spring tends to return the slider bar to misalign the receivers with the track openings. The detent balls are ramped upward out of the receivers into their upper operative position in contact with the downward opening locking recesses in the traveler.
