Patent CA-2134664-A1 (CA)
Inventor: WHEELER EDWIN L
IPC: H04M1/15
Filed: 1993-05-14
Abstract: The invention is a dual reel cord take-up device for flat wire cable which has a generally semi-cylindrical upper and lower case half which snap together over a dual-purpose shaft to make two compartments. The first compartment is a cord take-up compartment which is divided in two by a slotted rib on the shaft in that compartment. Flat wire cable is received in both sides of the compartment through apertures in the walls of the compartment. In the second compartment is a flat coil spring fixed on its outside end to a generally cylindrical spring cup within said compartment, and fixed on its inside end to the dual-purpose shaft in that compartment. The spring cup is biased against rotation except to tighten the spring, so the shaft is continually under tension to rotate and retrieve the cable into the take-up compartment.

Abstract: A system for eliminating differential scan line bow from raster output scanners aligns at least the chief exit ray of each scanning light beam with the system axis. By aligning the chief exit rays to be essentially parallel to the system axis, the overall bow is reduced, and the bow of different scan lines is essentially identical. Thus, bowed scan lines from different stations in a multi-station printer, or from different passes in a multi-pass printer are generally identical and aligned.

Title: Method and apparatus for utilizing the pressure of a fluid column generated by a pump to assist in reciprocating the pump plunger
Inventor: CHRISTENSEN BYRON D
IPC: F04B47/02
Filed: 1995-01-12
Abstract: The invention provides both a novel reciprocating pump for pumping fluid from a source by forming and moving a fluid column within a tubing, and a method of using the pump. The pump, which is particularly suited for oil wells, uses the pressure generated by the fluid column to increase the downward force acting on the pump plunger during the downstroke. The pump is provided with a reciprocablefirst surface which is in contact with the fluid column, a second surface which moves with the first surface and has a smaller cross-sectional area than the first surface, valve means cooperating with the second surface for subjecting the second surface to fluid at the pressure of the fluid at the source in the vicinity of the pump during movement in one direction and to fluid at the pressure of the fluid column in the vicinity of the pump during movement in the opposite direction. The magnitude ofthe downward force can be affected by regulating one or both of the pressure of the fluid column and the pressure of the fluid in the source.

Title: System and method for determining indicated pacemaker replacement time based upon battery impedance measurement
Inventor: KOOPMAN JAN
IPC: A61N1/37
Filed: 1996-03-28
Abstract: A programmable pacing system and method, the system having the capability for providing an indication of recommended replacement time (RRT) as well as a prior warning of six months to RRT. RRT is determined by storing a value in the pacemaker corresponding to battery impedance at RRT, continuously periodically measuring battery impedance, and comparing the measured value with the stored RRT value. Whenever the pacemaker is reprogrammed to different operating conditions which affect RRT, or there is a significant change in load lead resistance, a new value of RRT impedance is calculated based upon a selected formula corresponding to the reprogrammed set of operating conditions, and stored in the pacemaker. At the same time, an Aging value of impedance is re-calculated to provide a six month warning before RRT, and likewise stored in the pacemaker.
