Abstract: The bonding of a lead wire on a semiconductor having an ohmic contact metal electrode provided locally on a surface at a selected location is achieved through detecting the image of the metal electrode more precisely by enhancing the contrast between the metal electrode and the semiconductor surface. The enhanced contrast is accomplished by illuminating the contact-carrying surface at Brewster's angle with a beam of light rays having a wavelength in the range of the light transmission coefficient of the semiconductor material constituting the chip, and polarizing either the illuminating beam or the reflected beam or both to produce a difference in intensity of light between the contact and the light reflected from the semiconductor area. The illuminating light beam may be passed through a filter means to render a narrow frequency beam of light rays.

Abstract: Methods and apparatus are disclosed for consolidating loose or pre-compressed particulate materials, such as metal powder or metal flakes, in press equipment utilizing a reusable canister means that is sealed in vacuum from the atmosphere and heated prior to consolidation in the press equipment at elevated pressures and temperatures, thereby improving utilization of the press equipment.

Abstract: An article of rolled form constructed of card-like semirigid flexible material assembled by rolled assembly to form an article of annular cross sectional shape. The article is preferrably a megaphone with the advantages of having a complimentary handle comprised of a double thickness of the card-like material and additional tabs placed to add rigidity and maintain circular shape.

Abstract: The snow ski machine is a snow ski exerciser and teaching aid device which simulates the total motion of downhill parallel skiing minus forward motion consisting of two parallel simulated skis resting on a swivel near the skier's feet with said swivel being a pivot between the skis and a cart which follows two parallel rails horizontally moving from side to side by means of the shifting and transfer of the skier's weight with said cart pulling against two springs mounted on the center front and center back of the cart while the front of the skis rest unattached in guides which follow the angle of the skis on a pivot as the skier moves on the skiing device from side to side.

Abstract: This invention involves a gardening tool used as a rake where the tines of the rake are removably affixed to a bridge element. In the preferred embodiment circumferential banding clamps are used in conjunction with a sinuous wave shaped tines made of spring steel to affix the tines to the bridge of the gardening tool.

Abstract: A portable apparatus and system for supporting the lumbar lordosis region of the back of a human being including a panel and cushion assembled in supporting contact, with the panel being flexibly formed in the transverse shape of a columnar beam providing rigidity on the longitudinal axis of lumbar lordosis of the human being.

Abstract: The improvement in an electroluminescent lamp and the method of making same, including providing a polymer on the lamp structure and encapsulating the lamp with the polymer in a hard surface moisture impervious layer on each side of the device through the application of pressure and heat at selected conditions of pressure and temperature.

Abstract: The polarized potential at the boundary between a submerged pipe and a medium is measured unaffected by the presence of a distributed IR drop in the medium due to an impressed current from a corrosion protection system. The voltage between the pipe and a reference electrode in the medium is measured when the protection system current is zero. This is accomplished with a sample-and-hold circuit controlled by a trigger signal derived from the input signal and having a variable phase for controlling the phase angle at which the sample is taken.

Abstract: Systems and methods are provided to regulate the environment in a greenhouse where food and flower production is carried out, and in which outside air is inducted into the enclosure of the greenhouse through an evaporative cooler. A portion of the inducted air is recirculated, selectively heated or cooled and dehumidified, and mixed with the inducted air after contact with the agriculture in the greenhouse.

Abstract: A Miniaturized Bend Test (MBT) capable of extracting and determining mechanical behavior information from specimens only so large as to have at least a volume or smallest dimension sufficient to satisfy continuum behavior in all directions. The mechanical behavior of the material is determined from the measurements taken during the bending of the specimen and is processed according to the principles of linear or nonlinear material mechanics or both. In a preferred embodiment the determination is carried out by a code which is constructed according to the finite element method, and the specimen used for the determinations is a miniature disk simply supported for central loading at the axis on the center of the disk.

Abstract: A novelty greeting card with a hanging mobile configuration constructed of planar semirigid flexible material comprised of two hingedly connected side members. These side members have base portions which are bent into a perpendicular position to overlap and form a base foundation. This base portion supports an upper structure from which the hanging mobile or other visual attraction is suspended. The card and the hanging mobile are printed with appropriate visual indicia of a coordinated nature to enhance and complete the presentation of the card.

Abstract: A portable tent construction in which an outer tent of see-through "mosquito net-like" material completely encloses an inner waterproof weather tent which can be erected by the occupant from within the outer tent without the inconvenient necessity of exiting the tent. Implementation is uncomplicated and may be partially or totally completed as desired.

Abstract: A method and apparatus for the internal or blind side sealing of a small local leak (such as a void in casting). The sealing is accomplished by first drilling a hole in the conduit or container where the leak is located and setting a blind side sealer apparatus in the hole. The device consists of a guide that fits loosely into a drilled hole; a slitted metal conical capping means having an outside diameter approximately the same as the drilled hole diameter; a sleeve; and a retractable stem. The slitted cone is filled with a viscous sealant and the slitted cone part of the sealer assembly is pushed through the hole. Once on the other side of the hole, the slitted cone expands enough to prevent it from backing out. When the stem is pulled outward, the slitted cone is forced against the pipe or container wall, spreading the sealant. The stem then snaps at a necked-down position, signaling completion to the operator.
