Title: Means for gas-sealingly conveying shredded pulp
Inventor: SHACKFORD LEWIS D
IPC: B65G33/14
Filed: 1995-08-08
Abstract: A wall passageway, having openings therein only at opposite, inlet (14) and outlet (18) ends thereof, has a shaft (22) journalled therein. The shaft carries a screw thereon for moving shredded pulp through the passageway. The screw (24) is foreshortened, having a length less than that of the passage way, and causes inlet-admitted pulp to form into a continuously moving pulp plug. The plug, albeit having some porosity, comprises a gas seal within the passageway, and inhibits any migration of downstream gas from escaping to the atmosphere via the passageway and the inlet (14) thereof. In addition, a source (32) of oxygen or such gas as is inert to any downstream process is controllingly admitted into the inlet (14) to maintain an upstream pressure equal to, or greater than any downstream process pressure to insure against release of downstream gas into the atmosphere.

Patent CA-2209425-A1 (CA)
Title: Solenoid driver circuit
Inventor: GOODNIGHT TRENT LYNN
IPC: F16K31/06
Filed: 1997-07-04
Abstract: An electrical circuit applies an oscillatory electrical current to a coil of a solenoid in order to cause the solenoid to move in response to a command signal. The circuit includes a signal divider for generating an upper peak current signal value from the command signal and a lower peak current signal value which is a fixed percentage of the upper peak current signal value. A current sense resistor generates a current sense voltage representing current through the coil. A first comparator compares the current sense voltage to the upper current signal value. A second comparator compares the current sense voltage to the lower current signal value. A set/reset flipflop latches a current driver on and off. A current driver applies a driving current to the solenoid coil as a function of output signals generated by the first and second comparators so that the coil current will have a lower peak current value which is substantially a fixed percentage of the upper peak current value.
Patent CA-2211071-A1 (CA)
Title: Multilayer fused microwave conductive structure
Inventor: MCCORMICK JOHN A
IPC: A23L5/10
Filed: 1996-04-29
Abstract: A conductive structure for use in microwave food packaging which adapts itself to heat food articles in a safer, more uniform manner is disclosed. The structure includes a conductive layer disposed on a non-conductive substrate. Provision in the structure's conductive layer of fusel inks and base areas causes microwave induced currents to be channeled through the fuse links, resulting in a controlled heating. When over-exposed to microwave energy, fuses break more readily than the conductive base areas resulting in less absorption of microwave energy in the area of fuse breaks than in other regions where fuses do not break. The arrangement and dimensions of fuse links compensate for known uneven stresses in the substrate, giving uniform fuse performance. In addition, by varying the dimensions of the fuse links and base areas it is possible to design and fabricate different fused microwave conductive structures having a wide range of heating characteristics. Thus, a fused microwave conductive structure permits food heating temperatures to be tuned for food type.

Patent CA-2228867-A1 (CA)
Inventor: HARROUN JAMES S
IPC: H05G1/02
Filed: 1998-02-05
Abstract: A linear accelerator x-ray target assembly including an electron beam which contacts an x-ray target and generates x-rays. The target is mounted such that it can rotate freely about its axis. The target has a contoured axially outer edge. Fluid flow impinging the contoured axially outer edge of the target acts to impart rotary motion on the target. The fluid flow helps to dissipate heat from the target in two ways. Firstly, heat is transferred to a cooling fluid as the cooling fluid passes over the target. Secondly, the rotation of the target helps to dissipate heat from the target by distributing the electron beam contact point around the target instead of having the electron beam impact continuously on one spot on the target.
