Abstract: SYSTEM FOR BORING RAISES HAVING PORTIONS OF DIFFERENT DIAMETERS                Abstract of the Disclosure A raise boring system is provided for boring raise holes wherein the finished raise holes have portions of different diameters The system includes a raise head with a central drive stem defining an axis of rotation.  Primary cutter means are positioned on the raise head for disintegrating the earth formations out to a first radial distance from said axis of rotation.  Expanding secondary cutter means are positioned on the raise head for selectively disintegrating earth formations from said first radial distance out to additional and greater radial distances from said axis of rotation.  The expanding secondary cutter means may be selectively located in a first position either beneath or in the same plane as the primary cutter means during boring at said first radial distance from said axis of rotation and selectively located in additional positions for boring at greater radial distances from said axis of rotation.  Expansion means are provided for moving said expanding secondary cutter means to said additional positions during the boring operation.

Abstract: MANUFACTURE OF BUMPED COMPOSITE TAPE FOR AUTOMATIC GANG BONDING OF SEMICONDUCTOR DEVICES                 Abstract of the Disclosure A composite tape product, employed in the gang bonding of semiconductor devices, is manufactured on an insulating strip that has a series of apertures therein.  A plurality of metal fingers are bonded to the strip so that groups of fingers extend over the apertures.  The finger ends terminate in a configuration where each finger mates with an intergrated circuit bonding pad.  A thermocom-pression bonding tool can then gang bond the fingers to the bonding pads.  The tape mounted fingers then include the bonded chip and the tape can then carry the chip to the chip mounting and finger bonding operation.  The composition tape is manufactured using mating prepunched or pre-etched insulating and metal strips.  The metal strip is first partly etched to define the finger pattern.  Then the metal and insulating strips are bonded together so that the partly defined finger patterns register with the prepunched insulating tape aper-tures.  Then the finger etching is completed to term the composite tape that can be used in automatic assembly machines.

Abstract: COINCIDENCE GATE INK JET WITH INCREASED                 OPERATING PRESSURE WINDOW     ABSTRACT OF DISCLOSURE         In a coincidence vector gate ink jet, a droplet is expressed from an outlet orifice by a coincident pressure produced by a pair of transducers at an outlet orifice.  In this type of ink jet, it is normal for one of a cooperating pair of transducers to be activated in a non-coincident mode.  In the non-coincident mode, a droplet is not expressed from an outlet orifice as long as the pressure produced by the one transducer remains below a given threshold.  A pressure absorbing chamber is provided, which permits this threshold pressure to be substantially increased to a level substantially above the minimum coincident pressure produced by the pair of transducers to express a droplet from the orifice.  This increase in the threshold pressure is an increase in the operating window.  A greater operating window permits greater latitudes in manufac-turing variation and permits greater latitudes in pressure variation to change the size of a droplet to effect halftoning.

Title: Reflective beam rotator

Granted: 1982-12-21
Abstract: A REFLECTIVE BEAM ROTATOR     ABSTRACT OF THE DISCLOSURE    An apparatus adapted for rotating a beam of radiation to obtain azimuthal and radial time averaging of the intensity distribution incident onto a workpiece is disclosed.  The apparatus includes a housing adapted for rotation about a centerline axis, an entrance port and an exit port adapted for transmitting a beam of radiation through the housing, an inverter disposed within an internal passage within the housing and fixedly attached to the housing for rotation therewith includes a first mirror having a reflective surface angularly disposed to the rotation axis adapted for reflecting radiation incident thereon to a second mirror, a second mirror having a reflective surface adapted for reflecting radiation incident thereon to a third mirror having a reflective surface angularly disposed to the rotation axis adapted for passing radiation incident thereon through the exit port.  Radiation passing through the housing is rotated about its propagation axis at an angular frequency twice the angular rotation rate of the housing.  In one embodiment the third mirror has its centroid displaced from the centerline axis such that each ray in the rotating beam traces out an epicycloid instead of a circle thus averaging out some of the radial variations in the intensity distribution.  The effect of spikes, hot spots, or the like in the intensity distribution are effectively time averaged over an inter-action area on a workpiece when the rotation frequency is greater than the characteristic response time of the material of the workpiece.

Abstract: ABSTRACT Apparatus for treatment of humans with ultraviolet rays has one or more mercury lamps, Xenon lamps or other radiation sources and associated reflectors which establish a high-density radiation field in close proximity to the exit opening or openings.   The radiation is filtered so that the body of a person located in the region of the high-density field is exposed only to rays in the range of 315 to 400 nanometers.  The heat energy output of the radiation source or sources is sufficiently low to enable a person to stand long periods of uninterrupted exposure to radiation in the range of 315 to 400 nm so that a tanning effect can ve achieved as a result of a single con-tinuous exposure for a requisite interval of time.  Alternatively, the ap-paratus is equipped with suitable heat absorbing and intercepting means, especially if the radiation source or source are high-pressure mercury lamps or Xenon lamps.  The apparatus can constitute a table model, a floor model, a ceiling model, a wall model or a combination of these.

Abstract: JIG-SAW PUZZLE WITH IDENTICALLY     SHAPED AND SIZED INTERLOCKING         JIG-SAW ELEMENTS     Inventor Sam L. Savage ABSTRACT OF THE DISCLOSURE      A jig-saw puzzle in several embodiments which em-ploys identically shaped and sized interlocking jig-saw elements.  Since shape and size do not provide clues to position, the puzzle's working is increased in difficulty. In a first embodiment, the tesselate elements are shaped into the outline of a lizard.  They bear portions of a picture (e.g. a portrait) on one side and have lizard markings on the other side to allow it to be used as either a tesselation toy (lizard) or jig-saw puzzle (portrait side).  In a second embodiment the picture includes picture sub-units (such as a chair in a room picture) which may be inserted in different positions in the picture field formed by the puzzle.  This re-sults in a jig-saw puzzle with a number of different solutions.  A third embodiment is similar to the second but employs a straight line border.  Not all pieces of the puzzle are identically sized and shaped although a great number are, and even many of the edge pieces can be inserted in a number of positions along the edge.          This third embodiment may also employ moveable picture sub-units in the picture field.  In a fourth embodiment, one or more separate sub-puzzles may be interlocked to form a larger puzzle, as in a mural.

Abstract: ABSTRACT OF THE DISCLOSURE     A Safe, Dry and Free-Flowing Solid Peroxide/ Aromatic Carboxylic Acid Composition is prepared by mixing the solid peroxide, such as diacyl peroxide, dialkyl peroxydicarbonate, dialkyl peroxide or alkylidene diperoxide, which melts above 30°C, with a solid aromatic carboxylic acid, particularly unsubstituted or alkyl-substituted benzoic acid, which melts above 40°C.  This solid peroxide composition is used as an initia-tor for the polymerization of ethylenically unsaturated monomers, such as sytrene, and for curing of unsaturated polyester resins and diethylene glycol bis(allyl carbonate). This solid peroxide composition exhibits improved safety characteristics such as delayed ignition times when in contact with a flame and increased thermal stabilities compared to similar prior art peroxide formulations.
