  • Patent number: 4898392
    Abstract: A combined ring toss game and ball roll game. In a first embodiment, representing the ring toss game, a pair of target standards are used as targets for the rings. Each target standard is cylindrically shaped and is segmented so that an integral staking rod may be alternatively stored internal to the target standard or exposed at the lower end thereof for purposes of insertion into soil. When the staking rod is not used for holding the target standard in an upright attitude outdoors, the target standard is connected with a flat base. The flat base being suitable for use outdoors or indoors. Two differently colored sets of three rings each are preferred, and the object of the game is to score points based upon the accuracy of the toss of each ring in a set. In a second embodiment, representing the ball roll game, the two sets of three rings of the first embodiment are used as targets.

  • Patent number: 4827382
    Abstract: A multiple lamp shade system for a light bulb in which one of the lamp shades is rotatable and powered by heat given off by the light bulb. A multiply apertured base is held against a light bulb socket by surface contact with the light bulb. A light transmissible stationary inner lamp shade is attached at one end to the base. The other end of the inner lamp shade is partially occluded by a thrust plate on which is located an axially positioned upstanding pointed member. A peripheral annular gap is provided between the wall of the inner lamp shade and the thrust plate. A light transmissible rotatable lamp shade is co-axially mounted over the inner lamp shade and is bearingly supported via a bearing plate, at one end on the upstanding pointed member. A plurality of air vent chutes are annularly arranged adjacent the bearing plate. In operation, the light bulb heats the air within the lamp shades, causing an air convection current which upwells within the lamp shades.

  • Patent number: 4796062
    Abstract: A light level meter composed of a fiber optic cable having a light receptor end coupled to a conventional light meter is used for measuring illumination levels in spatially limited locations. By the method of the invention, a reference camera is calibrated for proper exposure settings using a series of test exposures. A light level reading is then taken using the fiber optic cable coupled light level at a location preferably near the camera lens. Identical secondary cameras are adjusted to have the same exposure settings as the reference camera, and the illumination for the secondary cameras is adjusted to match that of the reference camera by matching the secondary light level with the reference light level using the fiber optic cable coupled light level meter positioned at the same relative location at the secondary cameras as used for the reference camera.

  • Patent number: 4733414
    Abstract: A spring loaded drain cleaning device utilizing both positive and negative pressures to disrupt a clog. The invention is composed of a plastic hollow cylinder ending in an angled base cup having a gasket at its lower extremity, a cap at the top of the cylinder, a reciprocally mounted piston and a rod which permits the user to transmit forces onto the piston, and a biasing spring which acts on the piston. The user depresses the rod, causing the piston to descend down the cylinder resulting in fluidic compression in the drain above the clog, along with compression of the spring. Release of the rod results in a spring biased return of the piston up the cylinder, with an attendant negative fluidic pressure above the clog. The cycle is repeated in rapid succession until the clog clears.

  • Patent number: 4641395
    Abstract: A hinge for pivoting down rigger booms from a horizontal to a vertical position and vice versa. The hinge comprises two elements, one stationary and adapted to removably attach to conventional fishing down rigger bases, the other rotatable about a pivot having removable connection to a down rigger boom. The hinge is designed so that the stationary element has a "U" shaped member adapted for mating with an insert member of the rotatable element, the two elements being apertured so that a pin or bolt rotatably connects them together. Interlocking lips formed from the two hinge elements provide automatic holding of the boom in a horizontal position. A circularly curved surface on the stationary element and a circularly curved surface on the insert member of the rotatable element, in concert with the pivot point, form a guide for rotating the boom.

  • Patent number: 4638194
    Abstract: Presented is a new type of heat engine and process cycle utilizing, through the medium of superconductivity, a singular high temperature heat reservoir as a source of motive fuel directed into a low temperature region, the net effect being to cyclically process a superconductive substance magneto-calorically in H-T space so as to convert a thermal energies input directly into an available work energies output, without any need for a pressed, externally derived temperature variation, nor low temperature reservoir, for absorption of waste heats, to accomplish same, and which process is adaptable for both the direct generation of mechanical energy or electrical energy, in either mode being called a "Keefengine". The process of such conversions of ambient heat into utilizable work being called "Thermosynthesis", and being the product of the thermodynamic cycling of an "Envelopment", consisting of any number of mutually insulated "Segments" of size "d", where .sqroot.5.lambda.(T)<d<.xi.
