Patent CA-2154988-A1 (CA)
Title: Programmable dispensor
Inventor: WONG SECK MENG GEORGE
IPC: E03D9/03
Filed: 1995-07-28
Abstract: The present invention is a programmable dispensor for dispensing the appropriate amount of cleansing agents during peak period and adequate amount of cleansing agents during off-peak period without comprising the overall bacteria kill rate.  The dispensor features a microcontroller coupled toa solenoid valve for allowing users to program the dispensing of cleansing agents over a predetermined number of peak-hour intervals and at least one cut-off period. The dispensor of the present invention also incorporates a float subassembly within a bucket for receiving measured amounts of cleansing agents and accomplishing two important functions in response to the actual usage of urinal: (1) dosing the urinal upon demand when the urinal is flushed, and (2) dosing the urinal directly when the urinal is either not flushed or flushed infrequently.  Dosing on demand is carried out when a portion of the flushed liquid from the flush pipe is diverted to the bucket overa connecting pipe and an elbow channel. A float compartment of the float subassembly topples the subassemby which is pivoted over a hinge in the bucket. The cleansing agents mixes with the flush liquid before returning to the flush pipe. Direct dosing results from the overflow of cleansing agents from a tongue portion of the float subassembly through the elbow channel and connecting pipe into a discharge tube within the flush pipe. As such, a given supply of cleansing agents is guranteed to meet the pattern of actual urinal usage without comprising the overall bacteria kill rate in urinals.

Title: Alkali Metal Diffusion Barrier Layer
Inventor: FINLEY JAMES J
IPC: C03C17/34
Filed: 1995-09-11
Abstract: The present invention provides thin metal oxide barrier layers which prevent migration of alkali metal ions from glass substrates which comprise alkali metal into coatings on the glass surface, the properties of which coatings are susceptible to deterioration by the presence of alkali metal such as sodium.  The barrier layers of the present invention are effective at unexpectedly thin thicknesses, and have an optimal thickness range which is unexpected, in view of the expectation that a barrier layer will be increasingly effective with increasing thickness.

Patent CA-2164026-A1 (CA)
Title: Subband echo canceler
Inventor: DUTTWEILER DONALD LARS
IPC: G10L21/0232
Filed: 1995-11-29
Abstract: Failure to cancel echos at frequencies in which the frequency characteristics of sub-band filters in the X and Y analysis filter banks overlag in subband echo cancelers is overcome by employing an X-analysis filter bank in which the pass-band of the subband filters is wider than the pass-band of the corresponding subband filters in the Y-analysis filter bank. This insures that there is sufficient energy in the tap delay lines of the adaptive filters in thesubband echo cancelers at all frequencies where echos are to be synthesized. More specifically, the keeping of sufficient energy in the tap delay lines of the adaptive filters in the subband echo cancelers avoids exciting eigenmodes associated with the small eigenvalues of the correlation matrix.

Title: Golf Teaching Aid
Inventor: MABIE ANDY
IPC: A63B69/36
Filed: 1996-01-15
Abstract: A novel golf swing teaching aid golf club is provided herein. It includes a golf club which is simple in construction and is devoid of complicated mechanical, electrical or electronic gadgetry. The golf swing teaching aid golf club includes a golf club having a grip portion and a head portion, and a hollow cylindrical transparent shaft which is interposed between the grip portion and the head portion. The hollow cylindrical portion contains a predetermined volume of coloured, flowable, liquid of low viscosity. Such liquid is freely flowable, unimpeded, from one end of the hollow cylindrical transparent shaft portion adjacent to the grip portion to the other end thereof adjacent to the head portion to check the correctness of the swing of a golfer. Before the golf swing, the liquid adopts a position within the hollow cylindrical transparent shaft at a first selected marker line to provide an easily-visible correct attitude of the golf club, when the golf ball is addressed. Under the influence of centrifugal force during the golf stroke, the liquid thereby adopts different locations within the hollow cylindrical transparent shaft during the golf swing at selected further marker lines so as to provide an easily-visible indicator of the correct attitude of back swing, at golf ball impact and of follow through.
