Abstract: A removable and reversible wedge device adapted to be positioned on the sole of the cockpit of a pleasure boat that is heeling to provide the helmsman with a generally horizontal surface on which to stand. The wedge surface upon which the helmsman stands is preferably curved in the athwartships direction. The lower, sole engaging surface of the wedge device and the upper, support surface for the helmsman are provided with suitable non-slip materials.

Abstract: A heated bath of cleaning liquid is contained in an open top trough into which the bristles of a long handled car washing brush, having a nozzle enclosed within the bristles, are immersed. The edges along the top opening of the trough are provided with flow deflectors that are arranged to redirect liquid moving up the inside wall of the trough back into the bath. The handle is held in a stored position so that the nozzle directs cleaning fluid delivered thereto downwardly into the bath. Cleaning fluid is pulsed through the nozzle to produce heavy agitation in the bath to scrub soils from the brush bristles.

Abstract: A truss assembly for reinforcing concrete pipe that includes a mat into which has been woven a series of longitudinally spaced truss bridges that extend across the width of the mat. The mat is cast into a pipe at the points of maximum stress so that the bridges provide circumferentially positioned load carrying sections that are capable of resisting relatively high internal shear and tensile stresses.

Abstract: A strapping assembly and method for the treatment of acromioclavicular separations. The strapping assembly includes a stocking that is worn on the leg of the patient on the side opposite the injury and serves an an anchor. A tension member strap is connected to the stocking through an adjustable garter. From the stocking, the strap extends upwardly to the patient's shoulder on the side of the injury and then over the shoulder and downwardly to the patient's forearm. The strap is looped around the forearm to hold it sling fashion and the weight of the forearm places the strap under tension. After the strapping assembly has been applied to the patient, the acromioclavicular separation is reduced by the physician by closed reduction and then the tension on the tension member is adjusted to maintain the reduction.

Abstract: A floor brush comprising an elongated handle and a brush assembly connected to one end of the handle, the brush assembly consisting of a unitary brush block in which the brush fibers are set. The brush block is formed with an outwardly extending socket projection that has a relatively long tapered passage the inner end of which communicates with a shorter threaded passage of uniform diameter. An end of the handle is received in the socket projection and has a tapered portion conforming to the tapered socket passage and a threaded portion that mates with the threaded socket passage. When the threaded portions of the handle and socket projection are engaged, they operate to draw the conforming tapered portions thereof into close engagement with one another whereby the stresses in this area of the floor brush are uniformly distributed over a relatively large area.

Abstract: An adjustable, disposable suction device that is particularly adapted for medical use. The device is used for removing excess blood or body fluids from an open incision during surgery and is constructed so that it can drain the fluids from a point source or from a larger general area. In the latter case the device can be adjusted to control how much fluid is removed in a given period of time. The device is essentially comprised of a handle, a rigid outer tube formed with an oblique bend and a coacting flexible inner tube. The outer tube is connected at one end to the handle and has a plurality of longitudinally spaced radial apertures adjacent its free end. The flexible inner tube is positioned with a sliding fit in the rigid tube. The inner tube is open at its outer or free end but is otherwise imperforate. With this arrangement, the inner tube can be moved longitudinally within the outer tube to block all of the outer tube apertures or selectively open some or all of them.

Abstract: A bone-setting assembly essentially comprised of a pair of tubular members adapted to be inserted in the intramedullary passages of the respective parts of a broken bone, and a central connecting and aligning pin that is arranged to be slidably received in the interior passages of the tubular members. The tubular members are driven into position in the bone passages and a portion of the exterior surface of each member is roughened to firmly fix the member in the bone. The interior passages of the tubular members are preferably square in cross section and the central pin has a conforming square cross section so that there can be no relative rotation between the tubular members and thus between the parts of the broken bone. The central pin is threaded over approximately half of its length and a nut is threaded on this portion of the pin.

Abstract: A hand weapon that appears to be in innocuous key carrying device. The device includes a hollow handle member having a removable end cap to which a number of keys are connected through an axially movable plunger that passes through the cap into the interior of the handle. The inner end of the plunger is secured to one end of a relatively long cord normally stored in the handle, and the other end of the cord is secured to the handle itself. Coacting means are provided on the plunger and handle for releasably holding the end cap in position on the handle but the user can release the end cap which permits the keys to be hurled at an attacker.

Abstract: A cutting tool for use in conjunction with the propeller assembly of a boat to prevent underwater foliage from fouling the drive mechanism of the boat. The shank end of the tool is secured to the motor housing and supports the cutting blade end thereof in close proximity with the propeller hub. As the hub rotates, underwater foliage encountered by the propeller assembly is swept into contact with the cutting edges of the blade whereupon the foliage is cut and the cutting thrown away from the motor.
