Patent CA-2146492-A1 (CA)
Inventor: CHU DANIEL Y
IPC: B01D57/02
Filed: 1995-04-06
Abstract: Gradient gels for electrophoresis are produced by an apparatus in which a pair of syringes are mounted on a support rack together with cams arranged for synchronous rotation. Cam followers engaged by the cams are linked to the syringe barrels, with each cam defining a distinct spiral path translated by one of the cam followers into a preselected rate or rate profile of volumetric discharge from one of the syringes as the cam rotates. With the rate or rate profile established by one cam being distinct from the rate or rate profile established by the other, a gradient or other variation in composition is obtained when the syringe discharges are combined into a common stream and directed to the gel enclosure for solidification into a gel. The gradient or variation in composition is determined by the cam profiles alone, and is independent of the rate at which the cams are rotated, and of whether or not the rotation is performed in a steady manner. Theapparatus can be readily designed for manual operation with highly accurate and reproducible results.

Abstract: A steering assembly (10) for use in turning steerable vehicle wheels includes a rack (12) and a pinion (14).  A yoke (28) is continuously pressed against the rack (12) by a yoke spring (32).  The yoke (28) has a stem (62) which extends through an opening (64) in a housing (16).  During construction of the steering assembly (10), a desired range of transverse movement between the rack (112) and the pinion (14) is obtained by applying force (114) to the rack to position the rack at a first end of the range of transverse movement.  The direction of the force applied to the rack (12) is then reversed and the rack and yoke (28) are moved together away from the reference position until the yoke stem (62) has moved through the desired range of transverse movement.  A yoke plug (20) is then fixed against movement relative to a main housing section (18). After the rack and pinion steering assembly (10) has been constructed, it may be desired to check the range of transverse movement between the rack (12) and pinion (14). The distance between opposite ends of the range of transverse movement is determined by determining the distance through which the stem (62) on the yoke (28) moves relative to the housing (16).

Title: Synchronized clocks and media players
Inventor: MALOUF FREDERICK L
IPC: G06F17/30
Filed: 1994-03-31
Abstract: A media player and the clock which controls it are integrated into a single object This integration may be achieved by the construct of inheritance between objects in an object oriented programming environment.  A software class for player objects is established which inherits from a software class for clock objects. In this way, a player "is a"  clock. This integration provides improved synchronization among different media, and simplifies design of applications which employ player objects and clock objects. Each object is synchronized to a RootClock object which operates at the speed of the fastest media player in the system. The RootClock may be separated into "low" order and "high" order components and a compare register in order to induce interrupt overhead.

Title: Method and apparatus for production of radioactive iodine
Inventor: HASSAL SCOTT BRADLEY
IPC: G21G4/08
Filed: 1994-09-16
Abstract: Iodine-125 is produced by neutron irradiation of 124Xe gas to form 125Xe and permitting decay of 125Xe to form 125I. Irradiation of the xenon-124 is effected in a first chamber within an enclosure and decay is effected in a second chamber within the enclosure and free from neutron flux. The apparatus is submersible in a nuclear reactor pool so as to absorb any radiation escaping the apparatus during the process. Xenon can be caused to move between the chambers remotely, underwater. The second chamber is removable from said enclosure and is transported to a suitable location to recover the 125I from its interior. Such recovery is effected by admitting an aqueous wash solution into the second chamber, whereupon it is heated, causing water from the wash solution to reflux and cleanse the interior surfaces of the second chamber, thus creating an aqueous solution of 125I, which then is caused to drain into a suitable container.
