Patent CA-1288069-C (CA)
Title: Dna sequencing
Inventor: ORGEL LESLIE E
IPC: C12Q1/68
Filed: 1986-04-01
Granted: 1991-08-27
Abstract: DNA SEQUENCING              ABSTRACT OF THE DISCLOSURE        A first mixture is prepared that contains labeled chain fragments which each has a common end adjacent to a primary nucleotide and a termination at a position from the primary through an nth nucleotide, the first mixture containing nucleotide chain fragments of each length from termination at the primary through termination of the nth nucleotide.  A second mixture is prepared that contains labeled chain fragments beginning at the common end and terminating at positions from the first through the nth nucleotide, the second mixture containing chain fragments of each length terminating wherever either a first or a second of the four nucleotides occurs.  A third mixture is prepared that contains labeled chain fragments beginning at the common end and terminating at a position from the first through the nth nucleotide, the third mixture containing chain fragments of each length terminating wherever the first or a third of the four nucleotide sequences occurs.  The chains are electrophoresed with the first mixture as the center lane.  This three-lane system provides a unique band pattern for each of the four nucleotides and permits the sequence to be read merely by directly comparing each of the flanking lanes with the fully stepped center lane.  This system has important advantages in reducing reading errors, particularly when read with computer-assisted scanning apparatus.

Abstract: ELECTRONIC PUBLISHING SYSTEM                   A B S T R A C T    An electronic publishing system stores interrelated illustrations and items of text data, establishes data linking such items of text data to correlated locations in the illustrations, and stores such linking data in the recording part of the system.  Records of interrelated illustrations and items of text data fixed in tangible media for reproduction by user-operated electronic equip-ment may be produced in this manner.  One of the stored illustrations may thus be retrieved, and a display may be provided of that retrieved illustration.  The user then selects a desired location in the displayed illustra-tion, and the electronic equipment employs the stored linking data for retrieving any stored item of data corre-lated to the desired location in the displayed illustration.          The item of text data thus retrieved may be displayed, preferably in conjunction with the illustration to which it pertains.  Data linkage may also be between illustra-tion and interrelated illustration.

Granted: 1991-12-24
Abstract: ELECTRODE FORMATION               ABSTRACT OF THE DISCLOSURE A system and a method useful in the formation of electrodes for use in electrochemical cells are disclosed. The system includes a pair of conductive metallic terminal electrodes spaced apart from one another and disposed in an aqueous  electrolyte.   The  terminal  electrodes  are  in electrical contact with a power supply to effect a flow of current  in  the  electrolyte  away  from  the  first  of  the terminals and toward the second of the terminals.  At least one precursor electrode comprising A material to be reduced or  oxidized  in  electrical  contact  with a conductive backplate  is  disposed  in  the  electrolyte  between  the terminals.  The precursor electrode is orientated relative to the terminal electrodes so as to effect the reduction or oxidation of the material thereof.  Restraining forces are applied to the precursor electrode to substantially maintain the  dimensions  of  the  precursor  electrode  during  its reduction/oxidation.   The  system  includes  a  separator effective   in  permitting  the   precursor   and  terminal electrodes to interface with the electrolyte. The separator permits   a   substantially  uniform   application   of   the restraining forces to the precursor electrode.          No electrical contacts are made directly to the electrodes  being  formed,   this  process  then  being  a contactless charge.

Title: Copilot quick connect cyclic stick
Inventor: SMITH ANDREW
IPC: B64C13/12
Filed: 1988-06-14
Granted: 1991-06-25
Abstract: COPILOT QUICK CONNECT CYCLIC STICK     ABSTRACT OF THE DISCLOSURE     An aircraft flight control stick is mounted on a gimbal which provides left, right, forward and aft pivotal motion of the stick.  A pivot member that is mechanically linked to the aircraft flight controls is attached to the gimbal through a uni-ball bearing which allows the pivot member to pivot independently of the control stick.  A bell-shaped housing is slidably mounted on the control stick.  The housing is spring-biased downward toward the pivot member so that a stud protruding upward from the pivot member plugs into a socket in the housing.  A lever assembly mounted on the control stick and attached to the housing can be actuated to slide the housing away from the pivot member, thereby unplugging the stud from the socket to disengage the control stick from the aircraft flight controls.  The downward facing housing circumscribes all possible motion of the stud while the control stick is disengaged.  Release of the lever assembly allows a spring to urge the housing downward toward the stud.  The conical-shaped interior of the housing guides the stud into the socket to reconnect the control stick to the pivot member and the aircraft flight controls.  The reconnection of the control stick is accomplished rapidly without the possibility of jamming the flight controls.
