  • Patent number: 7090378
    Abstract: A portable travel mirror device includes a base, a handle pivotably mounted to the base, and a dual mirror assembly mounted to the handle which is pivotable and telescopically extendable between compact transport and upright use configurations, and includes a circular primary mirror frame holding a magnifying mirror encircled by a ring-shaped lamp energized by a power source within the base, and overlain by a diffuser ring. A secondary mirror pivotably and swivelably attached to the primary mirror frame has a different magnification factor, e.g., 1×, and is pivotable upwards from a travel position overlying and protecting the primary mirror to an upright use position, and is also swivelable into contact with the primary mirror frame, whereby light from the lamp is transmitted through the diffuser ring and a transparent secondary mirror bezel to illuminate objects in front of the primary or secondary mirror.

  • Patent number: 7063320
    Abstract: A portable game board has a ring-shaped frame containing at least one slide panel marked with indicia used to score trajectories of playing disks slidably launched on the slide panel, which comprises a base panel, an optionally segmented game indicia panel placed on the base panel, or a transparent window slide panel. A pair of base panels having different game indicia are positionable back-to-back within the frame, and selectable by inverting the frame. The board is optionally supportable at an adjustable elevation angle, quantifiably increasing the energy required to propel a disk to distance markers on a panel. An optional platform rotatably supports the game board, facilitating access to board locations by a circle of players. Optionally, an indicia panel contains one or more recessed magnetic slugs; playing disks are provided with one or more ferromagnetic inserts which interact with the slugs to alter the trajectory of a disk.

  • Patent number: 6913462
    Abstract: A dental prostheses modeling system includes a re-usable tray having in an upper part thereof a trough for receiving a semi-liquid casting material such as plaster of Paris or die stone, the trough having opposed vertical walls in which are formed alternating vertically disposed ribs and grooves for molding complementary shaped grooves and ribs in opposed sides of the base of a dental model casting molded in said tray. The trough has a base frame which overlies an upwardly concave lower cavity for receiving liquid die stone after the casting base has solidified, hardened and been removed. The base frame has therethrough an elongated aperture joining the upper trough to the lower cavity. A resilient insert is removably lodged in the base frame aperture to form therewith a liquid-tight seal, whereupon liquid die stone is poured into the upper trough to form the base of a dental model casting. After the casting has hardened, the insert is removed, and pins are fitted into selected portions of the cast base.

  • Patent number: 6840639
    Abstract: A dual magnification mirror system includes two mirrors having different magnifications, e.g., 5× and 7×, each mounted in a frame fastened to an opposite end of an elongated flexible arm. Each frame is so constructed as to enable it to be interchangeably placeable, mirror face down, on a horizontal supporting surface, such as that of a table or counter top, thus locating the other mirror above the supporting surface, at viewing position which is adjustable by a user by bending the flexible arm. The system also includes a wall mounting bracket fastenable to a vertical wall surface, the mounting bracket having on a front surface thereof a pocket for downwardly insertably receiving and supporting a peripheral flange which protrudes radially outwards from each mirror frame, thus enabling each mirror to be interchangeably inserted into the pocket, and thereby locating the other mirror at a flexibly adjustable viewing position spaced outwardly from the mounting bracket.

  • Patent number: 6817206
    Abstract: An air conditioning apparatus for isolated interior spaces of structures includes a hollow tubular-shaped enclosure which has a longitudinally elongated box-like shape. The enclosure has a transversely disposed inlet opening, a transversely disposed outlet opening, and a fan for drawing air through the enclosure from the inlet side, the air being expelled from an outlet port in the outlet opening of the enclosure. The enclosure also includes an air filter, at least one evaporator connected to a refrigerant compressor and refrigerant-to-water heat exchanger/condenser, and an evaporative cooler assembly including a plurality of nozzles for converting water supplied under pressure to the nozzles to fine spray. Water supplied to and warmed by thermal contact with pressurized refrigerant in the water heat exchanger, as well as excess water spray which does not evaporate, is discharged to a location exterior to the enclosed space, such as a sewer drain, thus dumping heat energy to the exterior location.

  • Patent number: 6799335
    Abstract: A fogless mirror for use in showers includes a shower arm adapter having a tubular body attachable at one end to a shower arm and at the other end to a shower nozzle; a bore disposed longitudinally through the tubular body conveys warm water from the shower arm to the nozzle, and a small orifice disposed radially through the tubular body diverts a small portion of water conveyed through the bore. A first rotatable coupler rotatably mounted to the shower arm adapter and angularly adjustable in a first plane conducts water diverted from the bore of the tubular body into a first outlet port boss. A second rotatable coupler rotatably mounted to the first outlet port boss and angularly adjustable in a second plane conducts water through a rigid tubular support arm to a mirror support frame, heating the mirror and thereby inhibiting condensation fogging thereof.

  • Patent number: 6695708
    Abstract: A golf putter includes a polyhedrally-shaped head having a plurality of generally vertically disposed ball-impacting faces which have different ball impacting characteristics and a shaft having at the lower end thereof a hosel terminated by a prism-shaped lower shaft end that has a polygonal transverse cross section. The head has protruding perpendicularly downwards from an upper surface thereof a centrally located bore having a polygonal cross section of the same shape but slightly larger than that of the prism-shaped end of the hosel, which is inserted into the bore at a selected angular orientation relative to the head to position a selected ball impacting face in a conventional ball-impacting disposition relative to the shaft grip, and releasably secured at that position by a screw inserted through the sole of the head and tightened into a threaded bore provided in the hosel end.

  • Patent number: 6667625
    Abstract: An apparatus for detecting whether bonding wire supplied to an ultrasonic bonding tool of an ultrasonic bonding machine is present in a bore of the tool tip and providing an alarm signal if a wire segment normally within the bore is absent because of inadvertent breakage or misfeeding of the wire includes an electronic switching and detection module connected between a machine ground terminal connected to a wire supply reel and a bonding tool electrically isolated from the machine ground. In response to an enable signal input to the module prior to making the first of a pair of ultrasonic bonds to interconnect a pair of binding sites by a bonding wire, electronic switching means within the module electrically isolate the machine ground from the tool, and electric continuity detection means within the module determines whether the tool has been brought to voltage level near that of the machine ground by electrical conductive contact between the wire segment within the tool bore, and the bore wall.
