The switch is electrically connected to other components of the dishwasher so that dishwasher operations are prevented when the switch is in the non-conducting state and so that dishwasher operations are enabled when the switch is in a conducting state.
Patent CA-2198951-A1 (CA)
Inventor: PUGIA MICHAEL J
IPC: C12Q1/37
Filed: 1997-03-03
Abstract: The present invention involves a composition and method for the determination of enzymatic activity or enzyme substrate concentration in a fluid test sample in which the enzyme catalyzes a reaction in a reagent system to provide a detectable response indicative of the concentration of the enzyme or enzyme substrate in the test sample. A measured amount of a protease capable of eliminating the enzymatic activity is included in the reagent composition, so that when a measured amount of test sample is treated, the reaction producing the detectable response will have a definite end point. The invention is particularly useful in conjunction with the determination of leucocytes in urine wherein the leukocytes are lysed to release their human leucocyte elastase which hydrolyzes a chromogenic ester to provide a phenol which then reacts with a diazonium salt to form a colored azo dye.
Patent CA-2200931-A1 (CA)
Inventor: LARSON GARY ROBERT
IPC: H01J29/28
Filed: 1997-03-25
Abstract: The present invention is directed to producing a luminescent screen used in a cathode ray tube (CRT) suitable for monochromatic or chromatic images, such as, those utilized in televisions, computers or data monitoring equipment, which require CRTs. The method of the present invention produces an ablative layer of the luminescent screen having a smooth surface with reduced surface distortions, such as, streaks and waviness, which are typically produced by conventional coating processes. When a reflective aluminum film is deposited on such a smooth ablative layer, the reflective aluminum film is also provided with a smooth surface, since it typically conforms to the underlying smooth surface of the ablative layer. As a result, CRT images having reduced distortions are produced. The method of the present invention further provides for enhancing the brightness of CRT images, which results from utilizing low ash producing polymers in the ablative layer and the binder of a luminophor layer of the luminescent screen. The method of the present invention further provides for combining the step for volatilizing of the ablative layer and the binder in the luminophor layer with the step for cementing of the face plate of CRT with the cone of CRT, without adversely affecting the quality of the hermitic seal between the face plate and the cone.

Patent CA-2219799-A1 (CA)
Title: Plow blade anti-drift stabilizer
Inventor: DEBOER GERALD PEARL
IPC: E01H5/06
Filed: 1997-10-31
Abstract: The present invention. comprises one or more anti-drift stabilizers mounted on the leading edge of a snow plow's blade.          These stabilizers are mounted at an angle that is in the same direction as the angle of the snowplow in relation to the plow truck. As snow or other media is channeled to one side of a plow blade it exerts a force in the opposite direction thus tending to cause a plow to want to knife or drift in a direction opposite where the snow or other media is being deposited by the blade.       As snow or other media passes over the surfaces of the stabilizers it exerts pressure that is opposite to, and counteracts the knifing action created at the emptying end of the plow be the accumulation of snow. The result of this is that the plow can be operated safely without the need to make constant corrections for the knifing and without the added danger of the inattentive operator being pulled from the roadway or into oncoming traffic and causing property damage or personal injury.

Title: Dicyclohexylmethane diisocyanate residue-based compositions and the use of such compositions as fillers
Inventor: SLACK WILLIAM E
IPC: C08G18/75
