Title: Flexible duplex dual port serial link controller
Inventor: CRABBE EDWIN P
IPC: G06F11/20
Filed: 1986-12-10
Granted: 1990-08-21
Abstract: A FLEXIBLE DUPLEX DUAL PORT SERIAL LINK CONTROLLER ABSTRACT OF THE INVENTION A multiple port serial link controller printed wiring card is shown. This printed wiring card provides at least two independent ports. These ports may be of different types such as RS-232 interface, RS-449 interface or other serial protocols such as HDLC, SDLC or BISYNC. These printed wiring cards may be combined in a duplex fashion to form two duplex (highly reliable) port transmission circuits. The duplex configuration requires a minimum amount of backplane wiring. This backplane wiring is permanent and requires no manual intervention for switching between transmission and mode types. Switching between transmission mode type and reconfiguring for the occurrence of faults may be accomplished by an automatic processor manipulation of a number of control points.

Granted: 1991-06-18
Abstract: BeF2-BASED OPTICAL FIBERS          Abstract Disclosed is BeF2-based optical fiber.  Such fiber can have, in addition to low loss, other advantageous properties.  For instance, BeF2-based dispersion shifted single mode fiber can have lower core-cladding index difference and larger core diameter than the corresponding SiO2-based fiber, and BeF2-based graded index multimode fiber can have larger bandwidth than the corresponding SiO2-based fiber.  The inventive fibers have a core and a cladding containing at least 30 mol% BeF2, and may contain up to 40 mol% of AlF3, and one or more members of the group consisting of NaF, KF, MgF2, CaF2, PbF2, PF5, and SiF4.  An exemplary and currently preferred glass has nominal composition (in mol percent) 30KF-(15-x)CaF2-xPbF2-10AlF3-45BeF2, with x< 15.  Single mode fibers according to the invention have minimum total dispersion in the range 1.5-2.0µm, and typically have 0.25% ? .DELTA.esi ? ? 0.6%, and 2.5 µm ? aesi ? 3.4 µm, where .DELTA.esi and aesi are the equivalent step index core-cladding index difference and core radius, respectively.  Rules and techniques that can advantageously be used to design BeF2-based single mode fibers are also disclosed.

Title: Fluid flow sensor
Inventor: PICHAT ALFRED
IPC: G01F1/698
Filed: 1987-03-12
Granted: 1991-05-14
Abstract: FLUID FLOW SENSOR     Abstract A fluid flow sensor especially adapted for use in solid state electronic system.The sensor employs a heated thermistor in a first sensing network with a temperature compensation means, the two being connected in common to a sensor point. A second network includes a threshold adjusting means and a diode power supply fluctationcircuit connected to a threshold point. The two networks are connected in a bridge circuit across a power supply. The thermistor responds to temperature changes associated with air flow changes to produce a change in circuit condition at the sensor point relative to the threshold point. A utility circuit responds to these changes in circuit condition to provide a desired response. The compensation network includes a plurality of diodes arranged to approximate the response of the heated thermistor to changes in power supply voltage such that the voltage at the threshold point closely tracks the voltage at the sensor point in response to to any such changes. This minimizes the utility circuit responding to the changes in bridge circuit conditions caused by power supply fluctuations rather than by changes in air flow velocity.

Title: Cathode and target design for a sputter coating apparatus
Inventor: HURWITT STEVEN D
IPC: H01J37/34
Filed: 1987-04-03
Granted: 1992-09-29
Abstract: ABSTRACT OF THE DISCLOSURE An improved cathode and sputtering target design for sputter coaling, permitting operation with larger cathodes and at higher power levels than heretofore possible.  The cathode and target assembly includes a cathode body, a target holder, and a sputtering target.  The cathode body function  as a magnetic pole piece, a portion of the cooling system, and a mechanical stabilizer for the target.  The target holder also provides cooling, by means of cooling passages and by intermeshing cooling means in contact with the target.  The sputtering target has an arch-like face that promotes a controlled plastic deformation in a preselected direction, so that heat-induced expansion during operation results in the target being urged into forceful, intimate contact with at least two cooled surfaces.

Abstract: ABSTRACT      A small animal trap of a type which can be economi-cally produced and  is constructed so that the user can discard it with the captured animal without any exposure to the animal.  The trap is in the form of a thin-walled enclosure  of  resilient plastic with a door  flap being formed  in  the surrounding wall by slits with a portion of the wall adjacent the wall being integrally attached to  the door flap so that the resiliency of the plastic allows  the  door  to  be  bent  inwardly  to  an  animal admitting condition but  is normally biased to a closed condition  in  which  it  is  flush with  the  surrounding wall.  A trip member, which may be made separate to the enclosure,  is provided for holding the door flap in the open condition and is connected to the door flap or wall in  a manner  to  readily  become  disconnected  if  it  is slightly moved by an animal entering or by the animal's activities within the enclosure.  The entire enclosure, including  the door  flap can  be molded as an  integral unit  in a single plastic molding step, and the form of the trip member, which may be a second molded part of the trap, can be of a simple form and constructed so as to permit the user to install it when setting the trap.
