Patent CA-2033646-A1 (CA)
Inventor: HERTZER RONALD A
IPC: B29C45/82
Filed: 1991-01-04
Abstract: A  hydraulic   injection  molding  machine incorporates a pump driven by a variable speed motor preferably of the brushless  DC type.   The machine controller outputs driving signals to adjust the speed of the motor so that the flow delivered by the pump substantially  matches  the hydraulic  demand  imposed during each phase of the machine operating cycle.  The pump is preferably a variable displacement type and is connected  to  a  fast  responding  pump  control  for selectively carrying out pressure compensation or flow compensation.  The values of the motor driving signals are calculated so that the motor/pump combination is operated at or near maximum efficiency except when the pump control varies the displacement of the pump to effect  pressure  or  flow  compensation.   Hydraulic transient response is further improved by connecting the output of the pump to an accumulator by way of a check valve.

Abstract: DRILL GRINDING MACHINE                 Abstract of the Disclosure A drill grinding machine employs independent servo motors for drill rotation, drill lift, and drill feed.  The three motors are connected through respective suitable drive mechanisms to a tubular spindle that is rotatably mounted within a work head.  The work head contains a hydraulic clamp for selectively chucking and releasing a drill holder.  A drill is gripped in the drill holder such that the drill point is proximate a grinding wheel.  The drill, lift, and feed motors are actuated to rotate the drill about its longitudinal axis and to move the drill point along a predetermined cyclical path of contact with the grinding wheel to grind a selected point.  Combinations of points may be ground on a single drill by suitably controlling the lift and feed motors.  A timing pad adjustably mounted to the machine housing cooperates with the lift and feed motors and the work head clamp to enable the drill to be manually timed prior to a grinding cycle.  Drill rock is selectively available through spring loaded contact between the work head and a hardened strip that is rotatably mounted in the machine housing.

Title: Misfire detection in an internal combustion engine
Inventor: JAMES JOHN V
IPC: G01M15/11
Filed: 1991-07-26
Abstract: A method and apparatus are provided for reliably detecting misfires in an internal combustion engine during actual driving conditions by monitoring fluctuations in engine speed between consecutive firing intervals. An average acceleration over a series of firing intervals is removed from an individual acceleration measurement corresponding to a particular firing interval to give an acceleration deviation which is then normalized to an expected torque to provide a power loss measurement. The power loss measurement indicates the occurrence of a misfire with a high signal-to-noise ratio. The information derived from misfire detection can be used to prevent destruction of a catalytic converter by unburned fuel mixtures and can be used to improve vehicle driveability by correcting for or indicating needed sevice for the vehicle. The misfire detection is implemented using existing sensors and processors and is adapted to be done on-board a vehicle in real time.

Abstract: Abstract Compounds useful to attach a fluorescein label to an oligonucleotide are disclosed.  To create these compounds, oxygen groups on the fluorescein moiety are protected (e.g. with acyl groups).  One then links a phosphoramidite to the fluorescein moiety via an amide or thiourea linkage to an active site on the fluorescein ring.  The resulting compound can then be directly linked to an oligonucleotide as the oligonucleotide is formed in an automated synthesizer and then deprotected using the same deprotection conditions are used to deprotect the oligonucleotide.  Such compounds are, inter alia, useful to create labelled primer  for DNA sequencing.     \fluor-lp
