Abstract: To simplify the manipulation of a dinghy between water and a storage location above high water mark, the dinghy is constructed so as to be circular when viewed in plan and is provided with pivotal means, such as a frusto-conical buoyant body having a bore, for receiving a handle whereby the dinghy can be rolled on its outer peripheral edge after the manner of a wheel, while being pushed, pulled and/or controlled by means of the handle. The handle may be in the form of a pole inserted by one end into the body and retained therein by rollers on radial stubs engaging with the undersurface of the dinghy floor. Other means, such as a peg loaded by a leaf spring engaging into a circumferential groove around the pole, may be provided for retaining the pole. An alternative form of handle arrangement may be in the form of a yoke providing arms which extend along each side of the dinghy and have respective pivot pegs engaging into the socket means from opposite ends thereof.

Abstract: A battery-powered lamp has a box-like casing with a top and side walls for housing at least one battery. At least one of the side walls has a depression which provides a generally planar depressed portion having an opening therethrough. A light source is supported in the casing. A lens, through which light from the light source can be transmitted, lens has a peripheral rim which is a friction fit in the opening. On its peripheral rim it has a plurality of ratchet-like teeth mutually spaced around the lens periphery. They make snap fits with and locate behind the material of the side wall bounding the opening so as to resist lens removal. Outside the peripheral rim of the lens is a surrounding flange which limits the depth of insertion of the lens in its opening. The side wall bounding the opening has a plurality of spaced notches which register with the lens teeth to prevent rotation of the lens relative to the opening. The lens teeth are triangular in configuration and are integral with the lens rim.

Abstract: A tool for chopping and scraping ice distinguished by a pair of arcuate portions which extend rearwardly from opposite edges of a straight sided intermediate portion which provides the chopping and scraping function, with the lower edges of the arcuate portions serving to pressurize the ice or mud and to force it forwardly in the direction of the straight sided intermediate portion.

Abstract: It is possible to extract mechanical energy from lower temperature heat sources than the flames of burning fuel by substituting driving fluids having lower boiling points than water and using an abentropic engine of the type described in my U.S. Pat. No. 4,109,470, both to condense the fluid for recycling and to obtain mechanical energy from the latent heat of the vapor. Thus, valuable energy sources now going to waste such as geothermal heat, solar heat, factory and power house smoke stack heat, and nuclear-waste heat are made to produce electricity via mechanical energy, virtually a reversal of the second law of thermodynamics, by use of an abentropic engine whose operational principle is that the latent heat of vapor is in fact potential energy which can be converted to mechanical energy during its condensation.

Abstract: A lamp having an elongated flexible support of a length to allow extension of the lamp in a plurality of directions with a lamp socket and hangable protector at its outboard extremity and a C clamp at its inboard extremity for holding the lamp in a selected position of adjustment.

Abstract: Method and apparatus for continuously-developing multi-layer tubing from plural ribbons of wrapping material of indefinite length layered in seriatim upon a continuously-formed mandrel serving as a temporary supportive base for the tubing. A driven cylindrical winding mandrel is rotatable about its longitudinal axis and has a plurality of longitudinally-extending serrations on its exterior periphery. A stationary driving helix is operatively associated with the winding mandrel means for feeding a workpiece in ribbon form through the driving helix. Initial pressure means proximate the driving helix allows the continuous curling of the workpiece radially inwardly into adjacent helical convolutions about the winding mandrel. This impresses serrations on the convolutions mating with the winding mandrel serrations in the generation of the helical coil configuration and the definition of a developing formed mandrel as a supportive base.

Abstract: A hand-held carrier for a pair of skis and a pair of poles includes a pair of confrontable clamping members hingedly interconnected at their lower ends. The members when in confrontation define a pair of adjacent ski-receiving openings (each for receiving the mid-section of a ski) and a pair of adjacent pole-receiving openings, (each for receiving the mid-section of a pole). The upper ends of the clamping members are releasably interengaged and are latched together by a latching means. A pivotable handle is mounted on one of the clamping members and may be swung as to allow a reduction in the space required by the carrier when loaded onto a car rack, thereby permitting the use of a greater plurality of carriers and supported skis and poles on a particular car.

Abstract: In a corrugating system, a supplemental means for insuring that the liner and corrugated medium are properly conditioned with adhesive or bonding material along the entirety of its length and width of the bondable surface as the machine is starting up following down time to avoid subsequent board delamination.

Abstract: A locating tool for facilitating the installation of relatively stiff floor covering material such as congoleum, linoleum, vinyl and similar sheet material comprising, a flat tool having opposed ends with edges for locating inside and outside corners and pipes or circular objects and opposed side edges for locating straight wall surfaces, locating tabs extending upwardly from the tool adjacent each side and end of sufficient length to produce an indentation in a piece of floor covering material pressed thereon, but not of sufficient length to completely penetrate the floor covering material, the locating tabs being inserted in such indentations when the floor covering material is rolled back and the tool laid on the bottom side of the floor covering material so that the end or side edges of the tool can be traced to provide an exact duplicate of the corner or wall being located, or one end of the tool can be utilized to provide an indication of the diameter of pipes or circular objects being located.

Abstract: A film-splicer for splicing together the abutting ends of a pair of films by means of a splicing label having supporting paper strips and a intermediate tear off piece. A base pivotally mounts a film-turning windowed flap. A pair of film clamps on the flap allow the locating of the film-ends-to-be-joined relative to the flap. An upwardly-facing projection extends upwardly from the base and through the window in the flap. Prongs extend upwardly from the projection for aligning the splicing label relative to the abutting film-ends-to-be-joined. A cam is pivotally mounted on the base. A folding and detaching pin has opposite free ends, is pivotally mounted on the flap, and extends across the window. The tear-off piece is folded in a hairpin-like manner around the pin by means of the cam.

Abstract: A screening apparatus for screening fibrous material in liquid suspension includes a housing having an inlet and accept fraction outlet and reject fraction outlet. The suspension is introduced under pressure via the inlet. A cylindrical screen is positioned centrally within the housing to define an involute reject passage within the housing and outboard of the screen with the rejected fraction passing under pressure from the reject passage outwardly of the housing via the rejected fraction outlet. The accepted fraction passes from the reject passage inwardly through the screen and is then passaged under pressure outwardly of the housing via the accepted fraction outlet. The suspension is under pressure in its travel through the apparatus and is pulsed en route by a plurality of elastically mounted diaphragms driven in compressing and decompressing strokes by means eccentrically mounted on a rotating mainshaft.
