Patent CA-2105498-A1 (CA)
Inventor: SCHRAMM LAURIER L
IPC: G01N13/02
Filed: 1993-09-03
Abstract: A method and an apparatus for determining the interfacial or surface tension, static or dynamic conditions, between two liquids or between a gas and a liquid under conditions of varying temperature and pressure; and a method for adjusting the interfacial or surface tension in a petroleum reservoir for enhanced oil recovery. A tensiometer is provided which is capable of measuring interfacial or surface tension under pressure and temperature conditions which simulate those present in an actual petroleum reservoir. Measuring the interfacial and surface tension values under actual reservoir conditions then enables the selection of surfactants and other materials for adjusting the interfacial and surface tension to desired values for optimizing the enhanced oil recovery from that reservoir. A tensiometer is provided which includes a calibration body which is imaged along with the image of the test droplet in the tensiometer chamber.   This imaging of both the calibration body and the test droplet provides the capability of correction of distortions in the image due to the nature of the chamber window for high pressure and/or high temperature measurements. The tensiometer is also provided with a surface against which the test droplet is imaged and measured, which is an annealed ionomer polymer coating on a polymer surface.

Title: Coating drum for cooked pasta
Inventor: NORMAN CARL M
IPC: A23L7/109
Filed: 1993-11-30
Abstract: A double walled drum of concentric cylinders having end seals and insulation between the cylinders. The drum is open at both ends and rotates on its center longitudinal axis which is pitched from the horizontal with the entrance on the high side. Diameter restrictions at the entrance and discharge ends of the drum increase product residence time. Lifters at the entrance end discharge end push flexible strandular food subject to microbial spoilage such as strands of cooked pasta away from the entrance and out the discharge. Pins are mounted perpendicular to the inner cylinder wall and point to the central axis of the drum. Liquids such as acid and oil are sprayed onto the food in the drum from a spray bar or spray manifold. The pins continuously lift and separate the strands of food while it moves through the drum, and mix the liquid and product, resulting in a uniform coating.   This process and apparatus produce a uniformly coated flexible strandular food such as spaghetti with minimal temperature loss.   The food is free flowing arid not tangled at the discharge of the drum. Surges from upstream equipment are suppressed, producing a uniform flow to downstream equipment.

Patent CA-2142487-A1 (CA)
Title: High velocity mist carpet cleaner
Inventor: REID DOUGLAS J
IPC: B08B3/04
Filed: 1995-02-14
Abstract: In carpet cleaning machines of the "steam cleaning" type, water is sprayed into the carpet to be subsequently extracted through a suction nozzle.  This process often results in overwetting of carpets causing a bad odour and longer drying time.  In this invention, I overcame this problem by first of all, converting the water spray system to a mist injection system.  This greatly reduces chances of overwatering.  I also control the depth to which the moisture settles in the carpet by means of a specially designed EXTRACTION CHAMBER.  This EXTRACTION CHAMBER forces the mist through and above the carpet but does not allow the moisture to settle to the carpet backing.  This is accomplished by a high velocity lateral movement of moisture through the carpet due to the EXTRACTION CHAMBER'S design and also due to the fact that a pressure and suction system are combined together within the EXTRACTION CHAMBER.  Thus the moisture is forced to pass laterally through the carpet and then up and out to the output compartment of the EXTRACTION CHAMBER.  Also, within the EXTRACTION CHAMBER, Bernoulli's Principle is used to advantage to prevent soaking down of moisture and to actually bring the dirt upward to the surface to be extracted.  The application of Bernoulli's Principle results in a continual upward movement of dirt particles within the carpet pile.  All these factors combined make this invention an excellent carpet cleaning tool which avoids the disadvantages of overwetting carpets.

Title: Process of procuding wood charcoal in a moving bed
Inventor: SCHMALFELD JOERG
IPC: C10B53/02
Filed: 1995-03-07
Abstract: The biomass, particularly lump wood, is supplied to a shaft reactor at its top and is initially preheated to temperatures of about 150 to 280°C and dried by a counterflowing hot gas. This is fol-lowed by a treatment in an underlying carbonizing zone, the upper portion of which is supplied with hot purging gas at a temperature of 250 to 600°C. The hot purging gas flows down-wardly through the carbonizing zone co-currently with the wood. A gas mixture which contains purging gas and gas produced by carbonization is withdrawn from the lower portion of the car-bonizing zone and is at least in part combusted outside the shaft reactor to produce a combustion gas, which is used at least in part as hot purging gas.

Title: Biosensing Meter Which Detects Proper Electrode Engagement and Distinguishes Sample and Check Strips
Inventor: WHITE BRADLEY E
IPC: G01N33/487
Filed: 1994-05-13
Abstract: A biosensing meter (50) receives a biomedical sample strip (10) which includes electrically isolated excitation (14) and sense (12) electrodes or, alternatively, a check strip. The biosensing meter includes first and second contacts (C, D) that are connected by a sense electrode upon insertion of a sample strip. An operational amplifier circuit has first and second inputs respectively connected to the first contact and a reference potential, the first input manifesting the reference potential as a result of a feedback within the operational amplifier. A processor (60) is coupled to the second contact and determines the presence of the reference potential at the second contact when an inserted sense electrode connects the first and second contacts. The processor also distinguishes between sample and check strips and tests for a proper impedance between the sense and excitation electrodes of a sample strip, thus enabling operation of the biosensing meter upon sample strip dosing.
