Inventor: VAN BREEMEN CHARLES A
IPC: B60G9/02
Filed: 1996-11-21
Abstract: A vehicle suspension system (21) features lower control rods (31) pivotally connected at their leading ends to hangers (29) attached to side frame members (27). The rearward ends of the lower control rods (31) are attached to axle seats (33) at each end of the axle (25), which are connected to the axle (25). Air springs (43) and shock absorbers (49) are mounted between axle seats (33) and side frame members (27). The lower control rods (31) are inclined with their forward ends above their trailing ends. Some embodiments of the suspension feature upper control rods (53) with their forward ends pivotally attached to the two opposing truck side frame members (27).

Patent CA-2247386-A1 (CA)
Title: Membrane filter with electrical and/or acoustic enhancement
Inventor: WAKEMAN RICHARD JOHN
IPC: C02F1/00
Filed: 1997-07-16
Abstract: This invention relates to tubular and flat sheet membrane filters, particularly those filters whose ability to separate particulate, molecular or ionic contaminants from suspensions is enhanced by the addition of electric fields to the filter. When a membrane filter is in use, contaminants from the feed liquid accumulate at the membrane surface to form a polarised layer which inhibits flow through the membrane. Contaminants in a liquid become charged and when subjected to an electric field will migrate toward one or other of the electrodes. If the electrodes are located either side of a permeable membrane or barrier, the contaminant can be caused to migrate by electrophoresis away from the membrane or barrier. The system can be made more effective by using a combination of ultrasonic fields and controlled hydrodynamic fields with the electric field. The ultrasonic and the hydrodynamic fields will improve the separation of the solids from the water and the electric field will cause the particles to migrate away from the membrane.

Patent CA-2249505-A1 (CA)
Inventor: ISHIKAWA KAZUO
IPC: B60G1/02
Filed: 1998-10-01
Abstract: A structure for supporting a hydraulic cylinder that controls pivoting of a rear axle in a forklift. The rear axle is supported pivotally to the body. The hydraulic cylinder connects the rear axle to the body. Two hydraulic oil chambers are defined in the hydraulic cylinder. Movement of hydraulic oil between the oil chambers is selectively permitted and prohibited to selectively permit and prohibit pivoting of the rear axle. The body includes a pair of side frame members located on the sides of the body and a pair of cross frame members connected to the side frame members. The rear axle is located under the cross frame members. One end of the hydraulic cylinder is pivotally connected to the cross frame members by an upper joint. An upper pin, which is part of the upper joint, is directly supported by the cross frame members. Accordingly, an exclusive bracket for coupling the hydraulic cylinder to the body is not necessary. This simplifies the structure for coupling the hydraulic cylinder to the body.
Patent CA-2249541-A1 (CA)
Inventor: MARRIE STEPHANE
IPC: G05B19/042
Filed: 1997-04-15
Abstract: The invention concerns the technical sector of optimization of industrial production, and especially of productivity. The general concept of the invention is the identification of the malfunction that is truly responsible for the stoppage of a machine production line, and the introduction of this specific variable into the man-machine interface for the handling of malfunctions. The true cause of a given breakdown is thus identified and can be acted upon, instead of acting upon secondary breakdowns down the line; the management of productivity is thereby very noticeably improved.

Patent CA-2253153-A1 (CA)
Inventor: STEEL JOHN
IPC: G03G7/00
Filed: 1998-10-30
Abstract: The invention provides a substrate for reception of an electrophotographic  image and use as a  film positive or negative  in  a  printing process.  The  substrate  of  the invention  does  not  display  the  disadvantage  of  reduced contrast in the positive or negative which has been caused in the past by areas of the electrophotographic image not being sufficiently solid as a result of mutual-repulsion of toner particles.  The substrate of the invention has a coating layer which has in its bulk a toner-coalescing agent which, under the  influence  of  the  heat  of  the  fusing  step  of  the electrophotographic process, brings about an improved degree of coalescence of the toner applied.

Title: Separator for fuel cell and manufacturing method for the same
Inventor: MIZUNO SEIJI
IPC: H01M8/02
Filed: 1999-01-18
Abstract: A separator for a fuel cell is manufactured by preparing a raw material powder, uniformly mixing the prepared raw material to be formed into a slurry, and charging the raw material powder derived from granulation into a metal mold for heat press forming. The raw material is obtained by adding to carbon powder a binder containing a mixture of phenolic resin and epoxy resin. Therefore the heat press forming step does not cause the binder to generate gas, thus allowing manufacturing of a separator exhibiting sufficient gas-impermeability.
