Title: Hybrid electronic detonator delay circuit assembly
Inventor: EWICK DAVID W
IPC: F42B3/13
Filed: 1997-12-03
Abstract: An electronic delay circuit (10) for use in a detonator (100) has a switching circuit (20) and a timer circuit (22). Switching circuit (20) controls the flow of a stored charge of electrical energy from a storage capacitor (12) to a bridge initiation element such as a semiconductor bridge (18) or a tungsten bridge.

Title: Method and apparatus for managing remote unit increased power transmission during location
Inventor: SANDERS STEPHEN H III
IPC: H04B7/26
Filed: 1998-01-13
Abstract: Remote units (113) that require locating are managed by a queue controller (180) such that the number and location of remote units (113) that are transmitting at increased power at any given time is limited. In particular, a queue controller (180) places identification information for remote units (113) requiring location onto queues (203) associated with base stations supplying reference pilots to the remote units (113). Additionally, identification (ID) information for the remote units (113) requiring location is placed onto queues (203) associated with base stations neighboring the base stations supplying the reference pilot to the remote units (113). The queues (203) operate on a first-in-first-out (FIFO) basis, that output remote unit ID  at periodic intervals. Once all queues (203) have been emptied of the ID of a particular remote unit (113), location takes place for that remote unit (113).

Title: System and method for harmonic interference avoidance in carrier recovery for digital demodulation
Inventor: COMAN ION
IPC: H03D7/16
Filed: 1998-01-15
Abstract: The present invention relates to an improved demodulator for locking onto and tracking a carrier. Harmonic frequencies are occasionally generated by demodulation circuitry. When this occurs, the harmonic frequencies can interfere with the demodulator's locking and tracking functions, especially if the harmonic frequencies are near a down converted carrier's frequency. A system and method are disclosed which provides an offset to a frequency synthesizer (107) whose output frequency (F1, F2) is used to down convert (104) the carrier. The offset alters the frequency of the down converted carrier so as to shift it away from the interfering harmonics. In this regard, the demodulator is enabled to lock onto and track a carrier when previously not possible.

Abstract: A pickup reel for a harvesting platform including a reel support structure with a reel shaft rotatably supported thereon. A plurality of radially extending arms are mounted to the reel shaft and a plurality of transverse rockshafts are mounted to the radially extending arms and are axially offset and parallel to the reel shaft and span the width of the platform. Radial fingers are mounted on each rockshaft. A cam is mounted to the support structure adjacent one or both ends of the rockshafts and defines an endless cam path about the reel shaft. A crank arm attached to each rockshaft carries a cam follower that engages the cam path for following along the path. The cam path is configured to cause the crank arms, and thus the rockshafts, to rotate about the respective rockshaft axis to vary the attitude of the fingers relative to the ground as the cam followers move along the cam path. The cam is segmented, having two or more cam segments joined together to form the endless cam path. The cam segments are joined together by removable fasteners to enable one segment to be removed and replaced to either vary the cam path or to replace a worn cam segment.

Le matériau ainsi comprimé et le plateau de moulage femelle interne sont ensuite envoyés par un transporteur à bande vers une cuve de vapeur où ils seront traités.
Patent CA-2296853-A1 (CA)
Inventor: GRIZZLE STANLEY E
IPC: E03D9/03
Filed: 2000-01-25
Abstract: A dispenser for treatment of water in flush toilet requires no float valve or moving parts to meter water treatment into the toilet tank. A plastic housing contains a charge of water-soluble water treatment in solid form (a block, granules, pellets or gel). The housing is completely immersed in the water contained within the toilet tank, and may be suspended in its operative orientation with a hanger that fastens to the rim of the tank. Water accumulates within the housing, dissolving the charge and releasing active water treatment agents. The housing is sealed against passage of water except for small openings in an upper portion of the housing, and water saturated with dissolved components accumulates in a lower housing portion, surrounding the charge and reducing the rate at which the charge dissolves. Dissolved components diffuse from the apertured upper housing portion into the tank; however, the effective flow area of the holes is minimal, and the charge is conserved. When flushed, a volume of liquid corresponding to the volume of the upper chamber flows into the toilet tank, and the flow entrains saturated liquid from the lower compartment.

Patent CA-2308234-A1 (CA)
Inventor: LANGERAK ROBERT
IPC: B01D63/02
Filed: 2000-05-05
Abstract: Headers are prepared with an opening including an inner space defining a part of a permeate channel. A thixotropic, water soluble gel is placed in the header in the space reserved for the permeate channel. A plurality of hollow fibre membranes are collected together and their open ends are inserted into the gel. A fixing liquid, typically a resin, is placed over the gel. The fixing liquid surrounds each membrane and then solidifies, simultaneously sealing the outer surfaces of the membranes and forming a plug in the opening of the header to complete the permeate channel. After the fixing liquid has solidified, the gel is removed in part by vibrating the gel to a liquid state or dissolving it. The space initially occupied by the gel becomes part of the permeate channel after the gel is removed.
