Patent CA-2353243-C (CA)
Inventor: ROBBINS ROBERT RALPH
IPC: E04B1/00
Filed: 2001-07-18
Granted: 2009-07-07
Abstract: A building levelling system is provided for a building having a basement or foundation supported on expansive soil. A water management system is included for maintaining water in the expansive soil at a level adjacent the foundation to saturate the soil with water and thereby prevent the cyclic shrinking and expanding of the soil when the soil is normally repeatedly dried and wetted, causing damage to the building supported thereon. An injection system may also be included for injecting water into the soil spaced well below the foundation to lift a foundation which has already settled significantly due to shrinkage of expansive soil upon which it is supported. The injection system includes a level sensing mechanism for determining when a level of water in a prescribed area of the expansive soil falls below a reference level of the system and injectors for feeding water into that area.

Title: Installation of upper skive plate in the fuser section of an electrophotographic machine
Inventor: MORGANTI TERRY N
IPC: G03G15/20
Filed: 2001-10-04
Granted: 2004-07-20
Abstract: A fuser section for an electrophotographic apparatus which includes an upper skive plate which can be quickly installed and removed without damaging the pressure roller. The skive plate carries a plurality of skives which strip a sheet of paper from the pressure roller during operation of the apparatus. To install the skive plate, guide openings in the plate are positioned on locator pins which are affixed to the load arms which, in turn, support the pressure roller. The plate is moved forward on the pins and is releasably latched in position by a pair of rotatable pawls on the plate which cooperate with clamping surfaces on the load arms. To remove the skive plate, this procedure is reversed.

Title: Improved shock absorber
Inventor: BELL STEPHEN H
IPC: B60G17/08
Filed: 2000-01-31
Granted: 2006-08-15
Abstract: The present invention provides an improved method and apparatus for controlling and making real-time adjustments to damping in a shock absorber (100) based on driving conditions and desired driving characteristics. The shock absorber has a reservoir compartment (122) and a fluid-filled internal chamber (120) divided into a compression compartment (130) and a rebound compartment (128) by a movable piston (126). A piston rod (138) is connected to the piston (126) and extends through a seal (174) in the rebound end of the internal chamber (120). The shock absorber contains flow passages (410) connecting, and normally allowing fluid to flow between, the reservoir compartment (122), the compression compartment (130) and the rebound compartment (128). Fluid flow in the flow passages (410), which is directly related to the relative motion between the shock main body and the piston rod assembly, is controlled by providing a variable valve closing force (112). Control of the valve closing force, and thus the damping of the shock absorber, may be controlled in real-time either by the vehicle operator or an autonomous damping control system.

Abstract: An automatic control system is provided for acid concentration in an aluminum strip cleaning line wherein an aluminum strip is contacted with an acid solution while passing through an acid cleaning bath and the concentration of the acid in the bath is adjusted by adding either concentrated acid or water to the bath. A conductivity probe provides a signal for the free acid concentration of the bath and an on-line process titrator periodically provides a second signal indicative of the actual free acid concentration and the total acid concentration. These first and second signals are used to obtain a corrected value for free acid concentration. The bath acid concentration is then adjusted as required based on the corrected specific conductivity value.
