Title: Instrument and method for intraluminally relieving stenosis
Inventor: ROTH ROBERT A
IPC: A61B17/22
Filed: 1990-04-26
Abstract: An instrument for and method of effectively dilating a stenotic region of a passageway of a portion of the living body, preferably the prostatic urethra, so as to relieve the symptoms associated with the stenosis. In the preferred system the tissue of at least selected portions of the prostate (172) are compressed (preferably with a balloon (8) inserted into the prostatic urethra so as to enhance hemostasis), and at least selected portions of the compressed tissue are denatured (preferably with a laser beam transmitted from within the passageway in selected radial directions) so that as the denatured tissue heals, the denatured tissue tends to shrink so as to effectively dilate the portions of the prostatic urethra. Ultrasonic transducers are used from within the prostatic urethra to image the tissue as it is denatured so as to monitor the procedure to insure proper exposure to the laser beam.

Title: Molded case circuit breaker combined accessory actuator-reset lever
Inventor: PANUS IRENAEUS S
IPC: H01H9/46
Filed: 1991-11-28
Abstract: MOLDED CASE CIRCUIT BREAKER COMBINED ACCESSORY ACTUATOR-RESET LEVER                   ABSTRACT OF THE DISCLOSURE    Since industrial rated circuit breakers are often located remote from the associated protected electrical equipment it is often times necessary to monitor the operation of such electri-cal equipment by observing the condition of the circuit breaker contacts to ensure that such equipment remains operational. When a plurality of such circuit breakers are mounted within a common enclosure, an auxiliary device within each of the circuit breakers readily provides visual indication of the ON-OFF condi-tion of the circuit breaker contacts.  With such auxiliary de-vices, an actuator-reset lever is used to interface between the circuit breaker operating mechanism, the circuit breaker trip mechanism and the auxiliary device to activate the auxiliary device when the circuit breaker contacts are open and closed and to reset the trip mechanism when the circuit breaker contacts are opened.

Abstract: ABSTRACT                    "ROD END JOINT"      A joint for connecting a tip member to the end of a rod or shaft.  The joint is particularly useful for joining a rod end to tip member of a material which is not easily brazed, cemented or otherwise adhesively joined together.   In the specific example described, a ceramic tip is jointed to the end of a metal rod, such as in a plug, a globe, or sliding stem valve.  A cavity in the interior of the top member has a narrowed opening at its top which terminates at a flat surface of the tip member.  A pair of wedge members, each of about 180 degrees annular extent, and the headed bolt end are all located in the cavity, with the wedge members oppositely positioned around bolt head. The bolt head and wedge members have complementary tapers so that motion of the bolt away from the tip member cavity causes the wedge members to move radially away from each other and preferably contact the side wall of the cavity, with the cavity being partially closed by an annular overhang through which the bolt shank passes.  The other end of the bolt is threaded and is received by a threaded hole in the end of the rod.   The face of the rod is in surface contact with the surface of the tip member.

Inventor: HOLT CHRISTOPHER E
IPC: H04M3/56
Filed: 1990-06-15
Abstract: A polyphonic (e.g. stereo) audioconferencing system, in which input left and right channels are time-aligned by variable delay stages (10a, 10b), controlled by a delay calculator (9) (e.g. by deriving the maximum cross-correlation value), and then summed in an adder (2) and subtracted in subtracter (3) to form sum and difference signals. The sum signal is transmitted in relatively high quality; the difference signal is reconstructed at the decoder by prediction from the sum signal using an adaptive filter (5). The decoder adaptive filter (5) is configured either by received filter coefficients or, using backwards adaptation, from a received residual signal produced by a corresponding adaptive filter (4) in the coder, or both. Preferably, the adaptive filter (4) is a lattice filter, employing a gradient algorithm for coefficient update. The complexity of the adaptive filter (4) is reduced by pre-whitening, in the encoder, both the sum and difference signals using corresponding whitening filters (14a, 14b) derived from the sum channel.

Abstract: The use of a conductive reactive braze material, loaded in via holes of a diamond substrate and heated in a suitable temperature range, results in conductive vias with excellent adherence to the via hole in the diamond material.  Cracking of the diamond substrate, and loose or lost via elements, are minimized.  A form of the disclosure is directed to a method for producing a circuit board having a multiplicity of conductive vias.  A generally planar diamond substrate is provided.  A multiplicity of via holes are formed through the substrate.  The holes are loaded with a conductive reactive braze material.  The braze material and the substrate are heated to a temperature which causes the braze material to melt and to react with the inner surface of the via holes and bond thereto.  In an illustrated embodiment, the braze material comprises a conductive matrix component that includes at least one element selected from the group consisting of copper, silver, and gold, and a reactive component that includes at least one element selected from the group consisting of titanium, chromium, vanadium, zirconium, and hafnium.   Another form of the disclosure is directed to a circuit board in which conductive vias pass through a diamond substrate and form a compound with the substrate at the inner surface of the via holes to bond to said inner surface of the via holes.

Abstract: COMMUNICATIONS ADAPTER BETWEEN TWO WAY ALTERNATE AND      TWO WAY SIMULTANEOUS COMMUNICATION LINKS                        ABSTRACT      A communications adapter interconnects a first device exhibiting a two way alternate (TWA) protocol and a second device exhibiting a two way  simultaneous (TWS)  protocol. The communications adapter comprises a transmit buffer for storing data received from  the first device via a first communication link for transmission to the second device via a  second  communication  link,  and  a  receive  buffer  for storing data received from the second device via the second communication link for transmission to the first device via the first communication link.   Data can be transferred in either direction between the transmit or receive buffer and the first device faster than in the same direction between the transmit or receive buffer and the second device.  To optimize  the  overall  transfer  rate  in  both  directions between   the   first   and   second   devices,   the   second communication  link  is  kept  busy  in  both  directions  by preventing the receive buffer from filling with data from the second device while the first device transmits data to the transmit buffer, and preventing the transmit buffer from emptying due to reading by the second device while the first device reads data from the receive buffer.
