Granted: 2004-09-28
Abstract: An electrical wire connector of the type having a wedge with converging side surfaces forcible into a C-shaped member between converging ears thereof, includes concave channel portions of the wedge side surface opposing arcuate inner surfaces of the ears to clamp a transmission line, stirrup, and strain clamp member therein under substantial clamping force to common and mechanically join them. The strain clamp cooperates with the electrical wire connector to prevent forces applied to the transmission line from being transmitted to the stirrup, thereby ensuring that a positive electrical connection is maintained between the transmission line and the stirrup.

Title: Displacement chromatography process
Inventor: PLIURA DIANA
IPC: A61K38/00
Filed: 1993-09-21
Granted: 2001-02-06
Abstract: Hemoglobin is purified from a crude solution thereof, to obtain an aqueous solution containing at least 99% of a preselected hemoglobin species, by a two stage displacement chromatography process. One of the stages is conducted under anionic exchange conditions, and the other under cationic exchange conditions. In both stages, the exchange column is overloaded to displace the hemoglobin species therefrom with contaminants having greater affinity for the column, and using the impure hemoglobin solution as the displaces. Normally, anionic exchange is conducted first, with contaminants more acidic than the hemoglobin displacing the hemoglobin from the column and themselves remaining attached to the column for separation. The cationic exchange process is conducted second, on the eluent from the first column, and in this stage, the more basic contaminants displace the hemoglobin from the column under overload conditions, to yield a substantially pure hemoglobin solution.

Patent CA-2107898-C (CA)
Inventor: DIXON ROBERT CLYDE
IPC: H04J13/16

Granted: 2001-07-03
Abstract: A wireless communication system including a repeated pattern of cells (203) in which base station transmitters (204) and user station transmitters (202) for each all may be assigned a spread-spectrum code for modulating radio signal communication in that cell. Radio signals used in that cell are spread across a bandwidth sufficiently wide that both base station re-ceivers and user station receivers in an adjacent cell may distinguish communication which originates in one cell from another. Adjacent cells may use distin-guishable frequencies and distinguishable codes, but it is sufficient if adjacent cells use distinguishable fre-quencies and identical codes. A repeated pattern of cells allows the codes each to be reused in a plurality of cells.

Patent CA-2113467-C (CA)
Inventor: MATAI MASAHIRO
IPC: H04W52/02
Filed: 1994-01-11
Granted: 2000-03-21
Abstract: Operation time of a receiving section is reduced by reducing a power supply to the receiving section upon reception of the signal of a self-transmission rate when another transmission rate signal and a noise signal are received, and power consumption is reduced. A timer section counts the time since a control section starts the power supply to the receiving section, and a transmission rate detector section is operated when a predetermined time has elapsed. Power supply to the receiving section is interrupted when the transmission rate detector judges that the transmission rate of the received signal is not a self-transmission rate. This reduces a power supply time of a battery.

Granted: 1998-06-23
Abstract: A system to determine fluid level in a tank using several tubes extending to different levels in the tank.  Gas pressure in the tubes needed to release bubbles from the exit ends of the tubes indicates the hydrostatic head at the exit ends.  A control unit compares the pressures in the tubes to find the highest fluid immersed bubbler tube.  The proportion of fluid above the immersed tube is calculated from the pressure and added to the height of the immersed tube to get the total fluid depth.  A spring loaded fixed length member, magnetically attached to the bottom of the tank, reliably secures the exit ends of the tubes at known fixed vertical locations.

Inventor: MAHONEY JOHN PATRICK
IPC: F16B5/02
Filed: 1994-10-24
Granted: 1998-08-18
Abstract: The disclosure involves a structural combination and a method for attaching a machine component such as a number of arc-shaped gear segments to a supporting segment mounting pad.  As new, each gear segment is furnished with a number of openings, all of the same diameter.  Initially, the mounting pad is free of openings and each gear segment is placed on the pad and used as a drilling template.  After openings are drilled in the mounting pad, a number of such openings (but not all) are "opened up" by reaming and a bearing-fit bolt is inserted into the reamed openings.  In repair, a new gear segment is placed at a position which spans two places formerly occupied by gear segments.  Certain openings in the new segment are aligned with existing openings in the mounting pad (to receive clearance-fit bolts therethrough) and other segments openings are used to form new openings in the mounting pad.
