Abstract: INTEGRATED CIRCUIT HAVING LASER-ALTERABLE METALLIZATION LAYER                 ABSTRACT OF THE DISCLOSURE      An integrated circuit and a method of altering such an integrated circuit (e.g., during final testing of the circuit) are disclosed.  The method can be used to program a circuit, wire around defective portions of a circuit, or otherwise permanently alter a circuit by employing a directed energy source such as a laser to sever electrical paths in an upper layer of metallization in an integrated circuit.  The integrated circuit comprises a laminated upper metallization layer, the upper layer(s) of which laminate are removed from the laser-alterable lower layer at selected locations in the metallization layer to provide laser-alteration sites in the circuit.  In a pre-ferred embodiment, the upper metallization layer comprises a two-layer laminate including an upper, relatively thick layer of an aluminum/silicon alloy and a lower, relatively thin layer of titanium nitride.

Title: Single-frequency time division duplex transceiver
Inventor: BEESLEY GRAHAM E
IPC: H04B1/56
Filed: 1989-03-15
Granted: 1992-11-10
Abstract: ABSTRACT         A time division duplex transceiver incorporating a dual conversion superheterodyne receiver, and in which the first receiver local oscillator (6) doubles as the frequency source for the transmitter.  The oscillator (6) is a voltage controlled oscillator VCO forming part of a mixer-type phase locked loop (21).  Frequency deviation in the loop is achieved by mixing the VCO output with a selected harmonic of the output of the second receiver local oscillator (11).  The reference oscillator is a crystal controlled oscillator (41) whose output is switched as between transmit mode and receive mode at a switch (55) before being passed to the loop phase detector (28).  The transceiver is able to rapidly and repeatedly alternate between transmit and receive modes and is thus well suited to time division multiplex operation.

Title: Rotor for magnetically sorting different metals
Inventor: WOLANSKI RICHARD B
IPC: B03C1/23
Filed: 1989-06-20
Granted: 1995-12-19
Abstract: A drum-like rotor having numerous, closely spaced, elongated rows formed of permanent magnets arranged end-to-end and secured to the outer surface of the rotor, produces a high-density, rapidly reversing magnetic field in a band-like zone which is spaced a short distance from, and extends along the length of, the rotor outer surface. The magnetic field induces eddy currentsin pieces of different metals passed through the zone which produces repulsive magnetic forces of different intensities in different metal pieces, and thus, magnetically separates such pieces. The row of magnets, in their radical direction, are alternatingly thicker and thinner, so that the outer surface of the thinner rows are depressed relative to their adjacent thicker rows. The outer surface of the magnets of each thicker row have a polarity which is opposite to the polarity of their next adjacent thicker row magnets, and the direction ofthe magnetic polarity of the magnets of the thicker rows are radial relative to the rotor. The side edges of the magnets of the thinner rows have the same polarity as the polarity of the outer surfaces of their adjacent thicker row magnets. The directions of the magnetic polarity of the thinner row magnets are generally circumferential, relative to the rotor. Thus, magnetic flux flows transversely through each of the thinner row magnets and then radially outwardly through their adjacent thicker row magnets, returning over the exposed surfaces of the thinner row magnets to the next adjacent row of thicker magnets and, thereafter, radially inwardly of the rotor and transverselyof the thinner row. Thus, the direction of the magnetic flux flow through the zone changes as the successive thicker and thinner rows pass alongside of the zone as the rotor rotates.

Title: Side-match and overlap-match vector quantizers for images
Inventor: KIM TAEJEONG
IPC: H04N19/94
Filed: 1989-09-21
Granted: 1993-03-30
Abstract: SIDE-MATCH AND OVERLAP-MATCH  VECTOR QUANTIZERS FOR IMAGES          Abstract There is disclosed a method and apparatus for data coding for image transmission or storage in which vector quantization enables good image quality at reduced transmission or storage bit rates by directly employing spatial contiguity with a prior block of data, or a one-row-prior block of data in a way that directly controls intensity continuity between spatially close pixels of the adjacent blocks in two directions. The technique includes both "side-match" (no overlap) and "overlap-match" vector quantization. The technique is relative demanding of memory space and logic capacity in the encoding of the image information; but the decoding can be relatively simple and thus is well adapted for archiving and subsequent retrieval of two-dimensional information.

Abstract: A seal for use around a rod electrode passing along an axis through a hole in the wall of a furnace into the interior of the furnace has an annular and at least limitedly flexible seal ring fitted snugly around the electrode in the hole and a holder carrying the seal ring and sealingly engaged with the furnace wall. Thus gas flow through the wall at the hole past the seal ring is substantially blocked. The seal assembly has structure forming with the electrode and seal ring a substantially closed chamber surrounding the electrode axially inward into the furnace from the ring. This chamber is pressurized at superatmospheric pressure with an inert gas and the electrode is cooled inward of the furnace from the seal ring. The seal ring is compressed axially by a packing assembly so it is pressed radially against the electrode. The packing includes rigid split compression rings bearing axially on the seal ring.

Abstract: A method for the isolation of a substantially pure L-isomer of an amino acid from its D,L racemic mixture does not require the use of a resolving agent, the formation of a derivative of the amino acid or additional enzymic reactions. The method is based upon the concept of the equal saturation point wherein the L-isomer can be separated from the D-isomer by precipitation of the L-isomer when the relative concentration of the D-isomer is less than 7.0% or by precipitation of the D,L racemate when the relative concentration is greater than 7.0%. Selective crystallization through seeding allows for further isolation of pure L-isomer when its relative concentration in solution is very low.

Abstract: A self-expanding stent formed of stainless steel wire arranged in a closed zig-zag configuration includes an endless series of straight sections joined at their ends by bends. The stent is compressible into a reduced diameter size for insertion into and removal from a body passageway.      The bends of at least one end of the stent are formed into eyes for connection with the eyes at one end of a similarly constructed stent to permit single-step introduction of several lengths of stent into the passageway. A stent can include a monofilament thread passing through successive eyes at one end of the stent, the thread passing through each eye at least once and through some of the eyes a second time. The trailing ends of the thread extend from the stent and outside the body passageway. The scent can be retrieved from the body passageway by threading a tube of the free ends of the thread until the tube is adjacent the stent.      The diameter at one end of the stent is reduced by pulling the free ends of the thread through the tube. A sheath concentrically disposed over the tube is introduced into the body passageway and over the remaining length of the stent to further compress the stent for removal from the passageway.
