Title: Method and apparatus for annealing stapler anvils
Inventor: MORIN DONALD A
IPC: B25C5/02
Filed: 1992-07-13
Abstract: ABSTRACT An anvil member for use in a surgical stapler is annealed by localized heating, preferably induction healing. A shaped shielding means is used to cradle the anvil so as to expose the staple crimping portion of the anvil.

Patent CA-2074422-A1 (CA)
Title: Insect attracting and capturing apparatus
Inventor: CHESHIRE JOSEPH M JR
IPC: A01M1/06
Filed: 1992-07-22
Abstract: "Insect Attracting and Capturing Apparatus"            An insect attracting and capturing apparatus particularly suitable for capturing and killing mosquitoes. The apparatus has a light source for attracting insects. A fan establishes an air current into an insect receiving opening, and establishes turbulent air flows in the vicinity of the apparatus. An air flow directing flange directs air into the insect receiving opening and into the fan. The insect receiving opening leads to a narrow channel that directs air into the fan. Insects having an upward flight reflex to sensed changes in air flow direction and/or velocity will detect the air flow created by the fan, fly upwardly, and be captured in the air flow. An electrified grid is provided inside the passageway for electrocuting admitted insects. The position of the electrified grid inside the channel and in the inward air flow muffles sound from electrocution of insects. One embodiment uses ultraviolet light as an attractant, and another embodiment uses light, heat and motion to attract insects. The apparatus has the appearance of a conventional outdoor lighting fixture, and therefore is aesthetically attractive and relatively quiet compared to conventional insect electrocution devices.

Patent CA-2089339-A1 (CA)
Inventor: BELUSA MANFRED L
IPC: F24F11/04
Filed: 1993-02-11
Abstract: BP File No.: 6780-002 An apparatus and method for space pressure control in high containment laboratories. The system comprises a volumetric air flow controller and a differential pressure controller. The differential pressure controller couples to the volumetric air flow controller. To establish negative space pressurization in the laboratory, the differential pressure controller generates a variable offset signal for volumetric operation. In response to the offset signal, the volumetric air controller controls the ducted supply air to the laboratory at a set shortfall compared to the ducted exhaust air flow. The shortfall of ducted supply air creates a negative pressure which is also sensed by the differential pressure controller. The differential pressure controller reduces the variable offset signal to zero once the desired negative pressure level is attained. To maintain the negative pressure level, the supply and exhaust air flow rates must remain equal. Any change in the negative pressure level is detected by the differential pressure controller which will generate the offset signal required to restore the negative pressure level. Furthermore, if the negative pressure level is completely lost, either bybreach of the laboratory containment barrier or by equipment failure, then system 10 will generate the offset signal for volumetric operation.

IPC: G02B6/35
Filed: 1991-09-24
Abstract: An optical fiber switch (10) in which the switching force is applied directly to the fiber (12). A biasing force, generated by a bending of the fiber (12), is exerted on the fiber (12) in a direction tending to urge the same toward the bottom (20 B) of a first groove (20). The switching force is applied transversely to the direction of the biasing force, and moves the fiber (12) out of the first groove (20) and into the second, adjacent groove. When in the second groove (22), the biasing force on the fiber urges the same toward the bottom (22 B) of the second groove (22).

Title: Apparatus to collect calling number identification data (cnid) into a personal computer without the necessity of maintaining the pc in a powered state
Inventor: BAER SCOTT J
IPC: H04M11/06
Filed: 1993-06-03
Abstract: AN APPARATUS TO COLLECT CALLING NUMBER IDENTIFICATION   DATA (CNID) INTO A PERSONAL COMPUTER WITHOUT THE NECESSITY OF MAINTAINING THE PC IN A POWERED STATE                          ABSTRACT      An apparatus for collecting calling number identifi-cation data into a personal computer without the neces-sity of maintaining the PC in a powered state.  The apparatus consists of a line interface that detects ring-ing, off-hook condition, and receives the information from the telephone line.  If the computer is turned off, the information is temporarily stored in a local memory.          A sequence of instructions is also stored in the memory.          Connected to the memory and the line interface is a microprocessor.  Under direction of the sequence of in-structions, the microprocessor receives the information from the line interface and stores it in the memory if the computer is in a powered down state.  When the com-puter is in a powered up state, the information is transferred from the microprocessor to the computer through a computer interface.  If any information was stored in the memory, the microprocessor retrieves that information from the memory before sending it to the computer.  Power partitioning supplies independent power to the line interface, the memory and the microprocessor, thereby allowing them to operate while the computer is turned off.  The computer interface receives its power from the computer.

Title: Anti-g suit with pressure regulator
Inventor: FARRELL PHILIP S E
IPC: B64D10/00
Filed: 1993-10-05
Abstract: Abstract of the Disclosure ANTI-G SUIT WITH PRESSURE REGULATOR          Inflating a fighter-pilot's anti-G suit to the correct pressure is facilitated by the pressure regulator design. Using Preview Control, the movement of the control stick is used to predict what the G-force on the aircraft will be in the time ahead. A computer determines what pressure is needed in the suit to safeguard the pilot at that G-force. The size of the air-flow aperture in the regulator is defined by overlapping windows in the housing and rotor of the regulator. The rotor is moved to give the correct overlap by means of a servo motor or stepper motor, which positions the rotor in response to the computer output. The very fast, stable, response of the regulator to the computer input enables the suit pressure to follow the G-forces predicted by Preview Control with great accuracy.
