Patent CA-2169867-A1 (CA)
Title: Environmentally safe work platform with buoyancy system
Inventor: WILDNER ROBERT J
IPC: B24C9/00
Filed: 1996-02-20
Abstract: A work platform assembly is modular in construction so as to be configurable according to the configuration and size, particularly width, requirements of each bridge and to metal surfaces thereof which are to be reconditioned by abrasive stripping and recoating. The assembled platform is suspendable at each end by suspension frame assemblies which are rollable along the parapets of the bridge for repositioning the platform assembly, with the suspension assembly being adjustable to various configurations of parapets. An adjustable curtain frame enables sealed enclosure of bridge surfaces to be treated and optimum access of workers to those surfaces during the treatment.  Airborne residue is evacuated by vacuum  for  subsequent  disposal  in  a  manner  which  does  not contaminate  the environment,  while  heavier  residue  and  spent abrasive grit is collected and positively moved off of the platform assembly  for  subsequent,  environmentally  safe  separation  and reconstitution of the grit for reuse.  The work platform assembly includes  a  floatation system which permits the work platform assembly to float in a body of water.   The floatation system facilitates the manoeuvring of the work platform assembly to better access surfaces to be treated.  Additionally, the floatation system of the work platform assembly facilitates the transportation of the work platform assembly to a structure located above a body of water.

Patent CA-2193894-A1 (CA)
Title: Galaxy turbine
Inventor: WOODS TIMOTHY JOHN
IPC: F03G3/08
Filed: 1996-12-24
Abstract: In a weight motor, it is known that friction can be among the most difficult elements to successfully accommodate. In this invention, three pinion gears are assembled to engage one another in-train and are further engaged by a cog wheel which surrounds them all, such that the sum of the pitch diameters of the three pinion gears equals the pitch diameter of the internally geared cog wheel. While the axles of the central pinion gear and one of the adjacent pinion wheels are seated in fixed bearings or journal boxes, the axle of the third pinion is un-anchored and unimpeded from rising or falling. However, because it must influence the activity of the other three gears (including the cog wheel) which together hold it in its place, its abilityto achieve rest/stasis at the "bottom" of the system can never be accomplished. Its own weight, or similar pressure against it, must cause it perpetually to seek a final rest point, yet never to reach it. A further pinion gear assembly may be constructed to impinge against the outer diameter of the cog wheel (where that cog wheel has had gear teeth cut into the outer diameter of it as well as into the inner diameter of it) and in line with the line/train described by the inner three pinion wheels. Such a train of gears is at right angles to the direction of gravity, or to the direction of a chosen alternative activating force. In most favoured design cases, gear assemblies are used "in-mirror", such that each assembly has a similar configuration/assembly of gears and related elements on the opposite (lateral, but virtually the same planel) side of the motor, and the proximal gears of such mirrored assemblies share two axles in-common.
Patent CA-2195261-A1 (CA)
Inventor: KIM CHENG
IPC: H04B3/23
Filed: 1997-01-16
Abstract: The detection of echo is enhanced using a coarse near-end speech detector at a Y-side of an echo canceler and using a more accurate near-end speech detector at the E-side of the echo canceler, such that the latter detector uses a representation of far-end speech and a threshold value to determine if the magnitude of the echo canceler output is larger than that of an echo signal only. If it is, and there is an absence of an indication of the presence of near-end speech from the coarse detector, then the more accurate speech detector adjusts the value of the threshold in a first direction, otherwise it adjusts the threshold in a second direction, to more "finely tune" such accuracy.

Abstract: According to the invention, the detergent or cleaner is mixed with water and this mixture is fed into a trade washing machine or dish washer. Thus, the detergent or cleaner is loaded continuously or in portions onto a weighing scale and from there supplied to a mixing vessel once a predetermined weight has been reached. At the same time water is allowed to flow into the mixing vessel, where a ratio of at most 5 kg per minute detergent or cleaner to 8 l water per minute is maintained. With this costeffective metering process, detergent or cleaner can be metered precisely in the standard amounts for commercial laundering or washing operations and fed in without any problem.
