Title: Fluorescent indicator dyes for alkali metal cations
Inventor: TSIEN ROGER Y
IPC: C07D273/00
Filed: 1989-11-14
Granted: 1998-01-06
Abstract: The invention discloses fluorescent chelator compounds that are especially useful to monitor and measure cytosolic concentrations of alkali metal cations such as Na+, K+, and Li+.  Particularly, the present invention relates to an aza-crown ether of the formula:               wherein the substituents are as defined in the specification.  The crown ethers may or may not have substituent groups attached to the core carbons, but will always contain at least one core nitrogen.  The crown ethers are linked via the core nitrogen(s) to at least one fluorophore that contains an additional heteroaromatic liganding center.  In the currently preferred dye, SBFI, the core compound is crown ether 1,7-diaza-4,10,13-trioxacyclopentadecane and the heteroaromatic fluorophores are benzofurans that are linked to isophthalate groups. Selectivities for Na+ over K+ of about 20 are observed, resulting in effective dissociation constants for Na+ of about 20mM against a background of 120 mM K+.  Increasing [Na+] increases the ratio of excitation efficiency at 330-345 nm to that at 370-390 nm with emission collected at 450-550 nm, so that ratio fluorometry and imaging work at the same wavelengths as used with the well-known Ca2+ indicator fura-2.  If the macrocyclic ring is increased in size to a 1,10-diaza-4,7,13,16- tetraoxacyclooctadecane, the chelators become selective for K+ over Na+.  If the ring is decreased in size, for example to a 1,7-diaza-4, 10-dioxacyclododecane, the chelators become selective for Li~ over Na+.

Title: Idle speed control apparatus
Inventor: KOBAYASHI YOSHIKYUKI
IPC: F02D9/02
Filed: 1990-01-29
Granted: 1994-09-06
Abstract: IDLE SPEED CONTROL APPARATUS                 ABSTRACT OF THE DISCLOSURE An idle speed control apparatus for controlling the idle speed of an internal combustion engine includes a main inlet air passage, a throttle valve positioned in the main air passage, a bypass air passage connected to the main air passage and bypassing the throttle valve, a control valve positioned in the bypass air passage, and an auxiliary bypass air passage which bypasses both the throttle valve and the control valve.  The control valve is responsive to a control signal to control air flow in the bypass air passage and regulate the idle speed of the engine.  A manually operable mechanism is provided in the auxiliary air passage for manually controlling air flow therethrough and adjusting the engine idle speed.  A first control signal causes the control valve to maintain the idle speed within a normally desired range.  To facilitate manual adjustment of the idle speed, an arrangement is provided which permits manual generation of a selection signal indicating that manual adjustment of the idle speed is desired.  A second control signal is produced in response to the selection signal and causes the control valve to maintain the idle speed within a reduced range which is substantially smaller than the normally desired range.

Title: Real time, fail safe process control system and method
Inventor: FIEBIG CAROLYN A
IPC: G06F11/20
Filed: 1990-03-29
Granted: 1994-05-24
Abstract: REAL TIME, FAIL SAFE PROCESS CONTROL SYSTEM AND METHOD     Abstract A  real  time  control  system  is  disclosed  for controlling  the   sequential   execution  of   scheduled operations  such  as  in  process  control  or  broadcast scheduling applications.   The  system uses  a fail  safe feature characterized as a sender/listener architecture.          An external clock input to the sender and the listener assures synchronous sequential stepping through identical schedules  stored  in  each  processor.   Under  normal operation, the sender processor controls the execution of events as they are sent from a host computer connected to the system.  Unscheduled events or errors are processed by being added to the schedule in real time for both the sender and listener processors.  The listener processor monitors the sender's signaling in the controlled network and, in the case of a failure in the sender, the listener immediately assumes control  of the  system as the new sender.   The  listener  executes  commands  which  were omitted  by  the  failing  sender  during  the  takeover interval  and  it  then  resumes  the  originally  intended schedule of process control events.

Abstract: A process for preparing an extruded elongate foam body characterized as having minimal surface defects such as pearls, streaks, foamy appearance and corrugations and having a density of between about 0.9 and about 3.5 pounds per cubic foot which comprises the steps of (A) heat plastifying a mixture of at least one thermoplastic resin and at least one nucleating agent; (B) adding at least one blowing agent selected from the group consisting of chlorodifluoro-methane; 1,1-dichloro-2,2,2-trifluoroethane;  1-chloro-1,1-difluoroethane; 1,1,1,2-tetrafluoroethane;  1,1-di-chloro-1-fluoroethane; 1-chloro-1,2,2,2-tetrafluoroethane and mixtures of two or more thereof to the mixture; (C) forming a blowable resin mixture by uniformly mixing the blowing agent and the mixture of step (A) in the resin under a pressure sufficient to prevent blowing of the resin; (D) extruding the blowable resin mixture through a die (20), which has a die lip temperature maintained at about 50°F to about 170°F and into a region wherein the blowable resin mixture expands into a foam body; and (E) cooling the foam body.      In one embodiment, the region of less than atmospheric pressure is formed by an elongated chamber (15) with the blowable resin mixture passing through a die at one end of such chamber and such foam body passing through a pool of water (17) at the opposite end of the chamber. The process results in the formation of extruded expanded thermoplastic resins such as polystyrene resins characterized as having relatively small average cell sizes such as from about 0.2 to about 0.5 mm., improved and higher compressive strengths, and higher cell volumes.

Title: Apparatus and method for decreasing the memory requirements for bios in a personal computer system
Inventor: BEALKOWSKI RICHARD
IPC: G06F9/445
Filed: 1990-07-05
Granted: 1993-11-09
Abstract: ABSTRACT     An  apparatus  and  method  for  decreasing  the  memory requirements  of  BIOS  in  a  personal  computer  system includes storing a first portion of BIOS in memory and a second portion on a direct storage access device.   The personal computer system comprises a system processor, a random access main memory,  a read only memory,  and at least one direct access storage device.   The read only memory  includes  the  first  portion  of  BIOS  and  data representing  the  type  of  system  processor  and system planar I/O configuration.  The first portion of BIOS only includes  routines  for  initializing the  system and the direct access storage device to read in a master boot record into the system from the direct access storage device. The master boot record includes a data segment and  an  executable  code  segment.   The  data  segment includes data representing system hardware and a system configuration  which  is  supported  by  the  master  boot record.  The first BIOS portion confirms the master boot record  is  compatible  with  the  system hardware  by verifying that the data from the data segment of the master boot  record  agrees  with  the  system  processor, system planar,  and planar  I/O  configuration.   If  the master  boot  record  is  compatible  with  the  system hardware,  the  first  BIOS  portion  vectors  the  system processor to execute the executable code segment of the master boot record.  The executable code segment confirms that the system configuration has not changed and loads in the  remaining BIOS portion  from the direct  access storage device into random access memory superseding the first BIOS portion.   The  executable  code  segment then verifies the authenticity of the remaining BIOS portion and vectors the system processor to begin executing the remaining  BIOS  now  in  random  access  memory.   The remaining BIOS in main memory includes reusable routines for operating the personal computer system in a normal manner.
