Patent CA-2194908-A1 (CA)
Title: Biodegradable air tube and spirometer employing same
Inventor: THOMSON RONALD A
IPC: G01F1/40
Filed: 1995-07-11
Abstract: Disclosed is an air tube (12) for use in a spirometer (10). This air tube (12) is disposable and is at least partially, preferably completely, biodegradable, so that it can be economically produced and discarded after use by a single spirometer user. Cross-patient contamination and expensive sterilization procedures are thus avoided. In addition, making this air tube biodegradable allows for the use of plentiful and inexpensive materials of construction, such as cardboard, paper, biodegradable polymers and the like, and reduces the environmental burden caused by disposing of this component.
Patent CA-2195822-A1 (CA)
Inventor: MONTEITH JOSEPH GORDON
IPC: B01D17/00
Filed: 1997-01-23
Abstract: A wastewater treatment installation includes at least two tank units having portions located in juxtaposed relation, the units being secured in such position. An inlet to the first tank unit communicates with a drop pipe connecting the inlet to a liquid delivery structure intermediate the top and bottom of the first tank unit, and located diametrically opposite the respective portion. The liquid delivery structure ejects liquid tangentially in opposite directions along the side wall of the first tank unit. An outlet from the second tank unit (or the last of a series of units) is located opposite the respective portion, and an outlet riser pipe connects the outlet to an intake opening, which is located intermediate the top and bottom of the second tank unit. A transfer opening at the juxtaposed portions connects each adjacent pair of tank units, and a diversion fitting associated with the opening between the tanks ensures that most of the liquid entering the second tank unit is ejected tangentially in opposite directions along the side wall of the second tank unit. This reduces the likelihood of scouring and discharging settled materials at the bottom of the tank units, and also the ejection of floating materials (oil, grease, etc.) captured in the tank units above the general level of the lower ends of the inlet drop pipe and the outlet riser pipe.

Title: Computerized payment system for purchasing information products by electronic transfer on the internet
Inventor: STEIN LEE H
IPC: G06Q20/16
Filed: 1995-09-14
Abstract: A payment system (10) for enabling a first Internet user to make a payment to a second Internet user, for the purchase of an information product deliverable over the Internet (12). The payment system (10) provides cardholder accounts for the first and second Internet users.  When the second user sends the information product to the first user over the Internet (12), the second user also makes a request over the Internet (12), the front end portion of the payment system (10) requests payment from the first user. The front end portion of the payment system (10) queries the first user over the Internet (12) whether to proceed with payment to the second user. If the first user replies affirmatively, a charge to the first user is processed off the Internet (12); however if the first user replies negatively, the first user is not charged for the information product. The payment system (10) informs the second user of the first user's decision and pays the second user upon collection of the charge from the first user.

Title: Hydro-thermo massaging tub and method of treatment
Inventor: BRUNELLE HENRY
IPC: A61H33/00
Filed: 1997-04-09
Abstract: A hydro-thermo massaging tub and method of massage treatment  is  described  and  wherein  the  treatment  is performed by warm air jets distributed adjacent the bottom wall of the tub all about its circumference.   Air jets are formed by holes made in the tub wall with the longitudinal axis of the holes oriented less than 45° from the plane of the  bottom  wall.    The  jets  communicate  with  an  air distribution duct which is fed hot air under pressure by a blower.  Controls are also provided to vary the pressure of the air as well as the temperature thereof.   Warm air jets are released in the water contained within the tub to impart turbulence  in  the  body  of  water  to  create  acupressure massaging  flows  of  warm  air  jets  and  water  flows  from opposed sidewalls and end walls of the tub towards a central area of least turbulence and which is occupied by the body of a person.   The acupressure massaging flows perform a massaging action all about the body simultaneously.  The tub also includes  a back  massaging  cavity  to  simultaneously massage the back.   Hot air circulating in the distribution duct also heats the neck and back portion of the tub where the neck and back of the bather rests during treatment.

Title: Refrigerator cabinet breaker assembly
Inventor: BANICEVIC NEDO
IPC: F25D23/08
Filed: 1997-05-29
Abstract: A refrigerator cabinet construction is disclosed where a breaker strip interconnects an exterior cabinet shell with an interior liner. The exterior cabinet shell has an open side and a shell edge flange. The interior liner is to fit within the exterior cabinet shell and has a liner flange extending outwardly of said liner. The breaker strip includes an exterior wall with first and second ended flanges. The breaker strip includes a first interior wall and a second interior wall projecting inwardly from said exterior wall to define a first channel. The first interior wall has a first flange co-extending with the first end flange of the exterior wall to define a shell receiving channel, wherein the shell edge flange is inserted into the shell receiving channel. A third interior wall is connected to second exterior wall and coextends with the second end flange of the exterior wall to define a liner receiving channel into which the liner flange extends. The third interior wall is joined through a hinge to a hinged flange adapted to pivot about the hinge and engage the liner flange and the liner during foaming to locate the liner flange in the liner receiving channel against the second end flange of the exterior wall. A magnetic strip is disposed in the first channel. The use of the hinged flange part of the breaker strip provides the advantage of having the breaker strip secure the outer shell relative to the liner while at the same time thermally insulating the outer casing shell from the inner liner.

Filed: 1997-01-29
Abstract: A process for producing an animal excretion treating article by classifying a pulverized paper diaper having a particle size of 4 mm or less to separate a paper powder and a highly water-absorptive resin from a plastic material. The plastic material from which the separation of the paper powder and the highly water-absorptive resin have been separated, is pulverized into a particle size of 4 mm or less and extruded and granulated to form a granulate having a grain size of 6 mm or more. The granulate is covered with a paper powder/water-absorptive resin mixture powder resulting from the pulverization of the separated paper powder and water-absorptive resin into a particle size of 1 mm or less. All of the starting materials can be obtained from a paper diaper waste powder, and thus, it is possible to provide, at an inexpensive cost, a granular animal excretion treating article capable of being incinerated even after being used, and a process for producing the same.
