Patent CA-2242507-A1 (CA)
Title: Ultrasonometer employing distensible membranes
Inventor: MORRIS RICHARD F
IPC: A61B8/00
Filed: 1998-08-20
Abstract: An ultrasonometer having opposed ultrasonic transducers with bladders containing a coupling fluid, controls the geometry of the bladder so as to provide immobilization of the patient as well as coupling of the ultrasound to the patient member. The coupling fluid may be hermetically enclosed in sealed chambers slideable toward the patient member or may be fixed in position and use a collar distending the membrane outward by compressing other portions of the membrane inward. A rolling diaphragm-type pump allows inflation of the membranes in an alternative embodiment without exposure of the acoustic coupling liquid to outside contamination. Temperature sensors and heaters communicating with the acoustic coupling fluid to reduce error caused by changes in the fluid's temperature.

IPC: A01G22/10
Filed: 1998-07-22
Abstract: A method and apparatus for the forming of artificial leaves and flower petals, especially for use as a craft item, includes a male form for forming an armature for the leaf or petal and a female mold for generating the leaf or petal body.  A flexible wire is wrapped about the male  form to  form  an  armature with an extending stem.  The armature is removed from the form and placed in the mold.  The mold is then filled with a film-forming casting material, such as a polyvinyl acetate.  Upon cure, the artificial leaf or petal is removed from the mold.  The leaf or petal may be combined with other leaves or petals similarly formed to form an artificial floral arrangement.

Abstract: There is disclosed herein methods and apparatuses for the improved recovery of fine fibers from a feed suspension consisting of long fibers, medium fibers, fine short fibers, contaminants and liquid carrier. In the preferred embodiment, a feed suspension is provided to a first filter in which it is separated into first and second fractions. The first fraction consists of fine fibers, contaminants and liquid carrier which have passed through the first filter. The second fraction consists of fibers, fine fibers and liquid carrier which have been retained on the surface of the first filter. The second fraction is then removed from the first filter for further processing or use in the paper-making process. The first fraction is then provided to a second device for separation into third and fourth fractions. The third fraction consists of fine fibers and liquid carrier which do not pass through the second filter. The fourth fraction consists of contaminants and liquid carrier which pass through the second filter. The third fraction represents fine fibers which would otherwise have been lost in the production process. The third fraction is then returned to the first filter at a location wherein the second fraction has formed. The fiber mat which forms the second fraction assists the first filter in retaining the fine fibers present in the third fraction while the liquid carrier passes through the second fraction and first filter and into the first fraction once again.

Filed: 1999-05-13
Abstract: A device for disposing of animal excrement comprising a box having an upper cavity with a motion detector, a sprayer of fluids, a drain, a step and a slanted floor, and a lower cavity with a vane pump, a macerator oar the impeller of the vane pump, a timer, a sprayer of fluids, and a valve for the control of the movement of fluids. A small animal stands on the step and enters the upper cavity and deposits excrement. When the animal leaves the upper cavity, the motion detector initiates the timer, which opens the fluid valve and fluid passes to the sprayer, which sprays fluid an the top end of the slanted floor.  The fluid is pressurized by the household supply and this pressure forces the animal extent to the drain in the bottom end of the slanted floor. The timer also turns on the pump which macerates the animal excrement and then forces the fluid and excrement out of the cattray and into a household drain. After sufficient time for cleaning of the excrement has elapsed the timer turns off the pump, and the valve.
