Abstract: ABSTRACT An  integrated  circuit (I.C.)   package in  which  an  I.C.   chip having flexible beam  leads, the inner lead  bonding sites of which  are bonded to input/output  (I/O) terminals  on the  active face  of the  chip is mounted active face down on the top surface of a substrate.  The top surface of the substrate is  provided with a chip  pad on which the  I.C.  chip is mounted and outer  lead (OL) pads.   The back surface  of the substrate  has a heat sink  pad  which  is positioned  substantially  opposite the  chip  pad.  A plurality  of  thermal  passages  is formed  through  the  substrate inter-connecting the chip pad and the heat sink pad.  A good thermally conductive material fills the passages.  A preform comprising a segment of fiber glass web  coated  with  a  thermosetting  and  thermally  conductive plastic is positioned on each chip pad between the chip pad and the active face of the I.C. chip.   The plastic material  of the preform  encapsulates the active face of  the chip, including a  portion of each of  the leads proximate the chip and secures the chip to the chip pad.  The outer lead bonding sites of the leads are  bonded to OL pads of the  substrate with exposed portions of the leads between the OL pads and the encapsulated portions being bent away from the  substrate and under  compression.  A heat  sink is bonded  to the heat sink pad.   The plastic material of the preform,  the chip pad and the thermally conductive material filling the  thermal passages provide  a low impedance thermal path between the I.C. chip and the heat sink.

Abstract: ABSTRACT OF THE DISCLOSURE    A saw-chain sharpening device is provided which is releasably attachable to a portable chain saw to enable routing-type saw chain cutters to be sharpened in situ on the chain-saw guide bar.  The sharpening device comprises a support bridge clampable to the saw guide bar in a position straddling one pass of the chain.  This bridge supports a grinding-wheel mounting arrangement which can be set up to orientate a grinding wheel carried thereby into the plane of the routing-edge face of a cutter to be sharpened.  Once correctly orientated, the grinding wheel is driven in rotation by external means (such as a conventional electric drill) and approached towards the cutter along a path lying in said plane.  This path is defined by a linear guide  of the mounting arrangement, the guide being slanted at the undercut angle of the cutter face.

Abstract: ABSTRACT OF THE INVENTION             A control apparatus for controlling the generators of a multiple steam generator or multiple hot water generator installation.  The control apparatus includes burner command apparatus which limits each of the generators to one of at least two different maximum firing rate levels.  The command apparatus is controlled by a data storage device, such as a microcomputer, which periodically adjusts the maximum firing rate level of the generators in accordance with the predicted loads of the installation.  The firing rate of the generators is controlled by modulating apparatus which varies the firing rate within the maximum firing rate levels in accordance with the actual measured installation load.  By controlling the actual firing rate in response to both the predicted and the actual installation loads, efficiency of operation may be optimized.

Abstract: Abstract of the Disclosure Implants may be placed in animals in the field with a system including an implanter and cartridge-like container for a plurality of implants. The cartridge is transparent and encloses a plurality of enlongated implants arranged side-to-side, transverse to the longitudinal axis of the cartridge.  The implants may be moved manually along the longitudinal axis of the cartridge toward one end and stopped in alignment parallel with the end of the cartridge and with one implant aligned with a pair of openings in the cartridge, one opening at each end of the implant.  The implanter carries a sharpened tubular needle and a plunger, slidable along an axis aligned with the central axis of the tubular needle.  The implanter has an opening into which the cartridge may be fitted and retained.  The implanter and cartridge have interfitting surfaces to position the cartridge with its pair of openings lying upon the central axis of the hollow needle and to retain the cartridge in the implanter so that the plunger may be passed repeatedly through the pair of openings in the cartridge and move the implants, one after the other, through the sharpened tubular needle into the animals.  The implants thus are protected from contamination until implantation.

Abstract: ABSTRACT OF THE DISCLOSURE    The present invention relates to an arrangement for detachably securing together the side-pieces and the shelves of a shelving structure, made of wood or a comparable material.  The arrangement comprises hook-like fasteners, each of which comprises an insert peg which is arranged to be inserted into an insert hole formed in a side-piece, and a binding peg which extends at right angles to the insert peg and which is intended to be removeably inserted into a binding hole formed in the shelf, to permit the shelves to be readily moved from one level to another in the shelving structure.  The insert peg is provided with a plate-like projection substantially at right angles to the insert peg.  The insert hole is of non-round cross-section, and the projection is such that, when an insert peg is inserted into a non-round insert hole and rotated through about 90° in the opening, the projections penetrate the wall of the insert hole, to prevent withdrawal of the insert peg therefrom.

Abstract: Abstract of the Disclosure A method for purifying aluminum that contains impuri-ties, the method including the step of introducing such aluminum containing impurities to a charging and melting chamber located in an electrolytic cell of the type having a porous diaphragm permeable by the electrolyte of the cell and impermeable to molten aluminum.  The method includes further the steps of supply-ing impure aluminum from the chamber to the anode area of the cell and electrolytically transferring aluminum from the anode area to the cathode through the diaphragm while leaving impurities in the anode area, thereby purifying the aluminum introduced into the chamber.  The method includes the further steps of collecting the purified aluminum at the cathode, and lowering the level of impurities concentrated in the anode area by subjecting molten aluminum and impurities in said chamber to a fractional crystal-lization treatment wherein eutectic-type impurities crystallize and precipitate out of the aluminum.  The eutectic impurities that have crystallized are physically removed from the chamber.          The aluminum in the chamber is now suited for further purifica-tion as provided in the above step of electrolytically transfer-ring aluminum through the diaphragm.

Abstract: Abstract:     A pneumatic percussor includes a three-way valve that is gated on by a control circuit to gate compressed air from a compressor to a percussor cup.  The percussor cup is resilient bellows that is expandable in response to pressurized air that is gated through the three-way valve. A variable orifice regulates the air flow to the percussor cup.  A check valve is connected in parallel with the variable orifice to exhaust air to the atmosphere.  The control circuit gates the three-way valve on for a short duration during which the percussor cup is inflated and when the control circuit gates the three-way valve off, the check valve relieves the pressure from the inside of the percussor cup to deflate it.  The expansion and contraction of the percussor cup delivers a therapeutic rhythmic action to the portion of the body external to the thoracic cavity thereby stimulating the expectoration of the mucus from the lungs.
