A body hull is used in the new water sport of body hulling. The body hull comprises a front panel that extends approximately to the thigh of a person wearing it. The body hull further has a back panel and buckles for connecting the two panels under the person's arms. In one embodiment, the front panel is a relatively flat skiff-like hullform design, but it has a slightly convex shape centered along a longitudinal axis. The person wraps a tow harness behind his shoulders and under his arms and at...

On a car body with a car body framework 1, for ease of assembly and effective utilization of space, in the vicinity of the side wall structure of each body framework field 7, a partial side wall element 8 is inserted that projects into the space between the corresponding frames 6.

A body positioner and the like is formed from a block of polyurethane foam having resilient characteristics capable of deformation and of permitting the passage of air and having an unsymmetrical pentagonal cross-section and having a length substantially greater than its width so that the block may be rotated on its major surfaces to provide for a variety of adjustable continuous positioning support surfaces along a major portion of the body of a patient while lying upon an operating table or ex...

A buoyancy body intended to be used in motorboats and sailing boats consists of a hermetically sealed flexible envelope containing a multiplicity of relatively small pieces of expanded plastic. The pressure within the envelope is slightly reduced so that the atmospheric pressure compacts the contents of the envelope.

A spool valve requiring a precisely cylindrical bore is cast about a wax core internally supported by a machined solid steel rod. Where desirable, the rod may be centered in a lathe and the wax portions of the core forming the bore are turned to the bore diameter. The casting is a powdered-metal filled resin spoxy resin which is formulated so that the exothermic curing reaction is controlled and does not affect the wax. The casting may be contained in a metal case which forms part or all of the ...

A small, lightweight sailboat comprising two floats, a horizontal frame to hold the floats, a vertical mast, a mainsail boom, a jib boom, a mainsail, a jibsail and rigging.

A bus body comprises elongated, one-piece panels extending substantially the entire length of the body and defining exterior and interior body sides and roof. A multiplicity of generally U-shaped, one-piece rib members, spaced at intervals along the length of the body and coupled adjacent their ends to the bus floor in an inverted position, are located between the interior and exterior panels and are joined to all of the panels. A plurality of stringer members, located along the joints between t...

A body restrainer is described particularly suitable for restraining disorderly patients who enter or are confined to institutions for medical care. In particular the body restrainer comprises a set of crossed belts which have quick engagement buckles which lock onto anchoring means attachable to a bedstead or stretcher. Additionally, the restraining belts have fastened thereto retractable loops for the insertion of the arm or wrist of the patient, which loops can be quickly drawn tight about th...

A porous seal element usable as a blade tip seal in a turbomachine or as an element of a labyrinth seal is made up of a large number of strips disposed edgewise to the sealing face of the element and extending in the direction of relative movement of the seal elements. The strips have grooves extending across the strip for discharge of a cooling fluid such as air. The presence of the grooves provides a low density structure at the seal face of the seal element which may be abraded if there is ru...
