Title: Use of ethyleneamines in the removal of lignin
Inventor: SHEFFIELD BYFORD D
IPC: D21C9/02
Filed: 1995-12-20
Abstract: Ethyleneamines are used in washing pulp to remove lignin. A process for washing a cellulose pulp mixture containing lignin to remove at least a portion of the lignin therefrom comprises use of a washing composition with at least 100 ppm of an ethyleneamine. The process includes an improvement in a washing process for a cellulose pulp mixture containing lignin wherein a washing composition is used to remove at least a portion of the lignin, the improvement comprising use of at least 100 ppm of an ethyleneamine with the washing composition and/or using an amount of ethyleneamine at least equivalent to 100 ppm based on the washing composition with the washing composition. The washing composition is also novel and includes a washing composition for washing kraft pulp comprising water and at least 100 ppm of an ethyleneamine.

Patent CA-2211583-A1 (CA)
Inventor: LACROIX CLAUDE
IPC: H02G3/12
Filed: 1997-08-13
Abstract: The stud bracket is used for mounting an electrical wiring box on a stud, particularly a metal stud. The bracket is made of a single sheet of a hand-deformable material. It comprises two initially flat leg portions which are initially provided in an L-shaped configuration. The first leg portion features a lateral strip used to either grip an edge of a metal stud or serve as a positioning guide. The second leg portion comprises an outer section surrounding an elongated inner strip that is delimited by a continuous cut leaving only an end of the inner strip, opposite the first leg portion, integral with the outer section. The bracket is very versatile and allows the electrical wiring box to be connected without tools to various positions on a wide variety of studs.
Patent CA-2211974-A1 (CA)
Title: Portable solar shower system
Inventor: MCCORMACK ALAN EDWARD
IPC: A47K3/28
Filed: 1997-08-27
Abstract: As a portable showering system intended for both consumer and industrial applications, the system will provide for the universal mounting on a wall, post, shelf, a top a recreational vehicle or slung from a tree and not limited to the aforementioned, through the use of various mounting apparatus contained as optional equipment in the portable showering system kit. Installation can be performed by a literate adult equipped with screwdriver, pliers and household power drill with assorted bits. The 20 litre solar heated reservoir supplies a generous amount of showering liquid to the shower head via communicator plumbing in a fashion typical to regular household shower units and for a duration of up to 7 minutes. The reservoir does not require source plumbing or any man made pressure device as the system is gravity fed. A push/pull rod of discretionary length controls the open/close valve and allows for instant and variably controlled release of showering liquid to the user. The instant open/close capability of the 1/4 turn ball type valve controlled by the push/pull rod, mounted with rigid plumbing and working in conjunction with a removable shower head with garden hose adapter, allows the user to either dispense shower liquid, or refill the reservoir via the shower head by means of a regular garden hose with ease.
Patent CA-2212308-A1 (CA)
Title: A solenoid valve control device
Inventor: AKAMATSU OSAMU
IPC: F16K31/06
Filed: 1997-08-01
Abstract: Three-position solenoid valve which outputs an output pressure and can adopt exhaust, overlapping and supply positions.  The output pressure is detected by an output pressure sensor and is fed back to a fuzzy control unit.    Based on the difference between the output pressure and the command pressure corresponding to the pressure command signal from the brake control unit, such fuzzy control unit calculates a command current value for controlling the three-position solenoid valve by fuzzy reasoning.  The command current value can adopt an essentially continuous value, and consequently the three-position solenoid valve can adopt a gentle exhaust state or a gentle supply state.  In this way, sudden changes in the output pressure can be suppressed and the output pressure can be made to converge rapidly on the command pressure and eliminate overshoot and undershoot.
