Patent CA-2037601-C (CA)
Inventor: HEERTEN GEORG
IPC: D04H1/46
Filed: 1991-03-06
Granted: 1998-11-24
Abstract: A water and/or oil-impermeable sealing mat is provided in form of a bentonite non-woven fabric combination with the possibility of transmitting shear from one batt layer to the other, i.e. on a slope shearing forces can be transmitted by the covering batt material through the layer of swellable clay into the supporting batt material. Such a sealing mat is a fiber-reinforced mineral seal permitting the transmission of shearing forces on slopes, without the risk of the layer of swellable clay itself becoming the preferred sliding plane. The sealing mat consists of a non-woven textile material as substrate layer, a layer of swellable clay, preferably sodium bentonite, and a cover layer consisting preferably also on a non-woven textile material, all three layers having been needlepunched together in the conventional manner in a needle loom. When moistened, the clay swells and forms the water and/or oil-impermeable layer. The water and/or oil-impermeable sealing mat is used especially in hydraulic engineering and in waste disposel engineering.

Title: Enzyme electrochemical sensor electrode and method of making it
Inventor: RISHPON JUDITH
IPC: C12Q1/00
Filed: 1990-12-10
Granted: 1997-12-02
Abstract: An electrochemical sensor electrode is formed from an electronic conductor (26) coated with a matrix (28) containing a perfluorosulfonic acid ionomer and a selected enzyme. The selected enzyme catalyzes a reaction between a predetermined substance in a solution and oxygen to form an electrochemically active compound that is detected at the electronic conductor. The resulting perfluorosulfonic acid polymer provides a stable matrix for the enzyme fox long lived enzyme activity, wherein only thin coatings are required on the metal conductor. The polymer also advantageously repels interfering substances from contacting the enzyme and contains quantities of oxygen to maintain a sensing capability during conditions of oxygen depletion in the sample. In one particular embodiment, glucose oxidase is mixed with the perfluorosulfonic acid ionomer to form an electrode for glucose detection.

Granted: 1996-12-17
Abstract: An image rotation method and an image rotation processing apparatus in an image processing apparatus are disclosed. The image rotation method obtains the coordinates (x',y') of a second memory where the rotated image will be recorded, by sequentially scanning a first memory where the M?N original image is recorded and adding the increments of x and y corresponding to a rotation angle .theta. repeatedly, and transmits the image element data of the coordinates (x,y) of the first memory to the coordinates (x', y') of the second memory with one-to-one correspondence, thereby obtaining the rotated image through the rotation angle .theta. from the original image. Thus, the present invention can obtain the rotated image using only addition operations and without any multiplication operations, so that high-speed operation is possible and an image can be rotated through a specified angle .theta. through software in common computer graphic systems having no floating point multiplier.

Granted: 1996-05-28
Abstract: A fish retaining device consisting of an elongate support having a first end and a second end.  A transverse brace member is secured to the first end of the elongate support for suspending the elongate support in an opening made through ice for ice fishing such that the second end of the elongate support extends toward a bottom of the ice opening.  A frame is secured to the second end of the elongate support.   The frame has a central passage and extends substantially perpendicular to the elongate support.  The frame substantially fills the ice opening such that there is no room for a fish to pass between the frame and the ice opening.  A one-way gate is pivotally mounted to the frame.  The gate pivots toward the first end of the elongate support such that clearance is provided for the passage of a fish through the central passage of the frame into the ice opening.  The gate rests upon the frame which serves as a stop preventing the gate from pivoting toward the second end of the elongate support thereby closing the central passage and retaining the fish within the ice opening.

Title: Harrow carts
Inventor: MAY R ELWIN
IPC: A01B73/02
Filed: 1992-03-19
Granted: 1995-06-06
Abstract: A cart or "caddy" is provided for operation and transport of one or more chain harrows, the cart consisting of a frame running on a pair of road wheels.  Different harrow mountings can be mounted on the frame, all of which include a draw bar to which the harrow is attached for operation.  All of the mountings enable the draw bar to be lifted from the ground and then the body of the harrow to be engaged by one or more spaced cross bars parallel to the draw bar and over which the harrow is draped to store it and permit it to be transported on the cart out of contact with the ground.  Some of the mountings are pivoted to the cart frame about an axis that in the stored position is vertical, so that the mounting and harrow can be turned longitudinally to reduce the effective width and permit the use of harrrows that would otherwise be too wide to be moved over public roads.  Wider arrangements use two harrows that operate side-by-side on mountings that are pivoted individually so that they can be turned to be parallel to one another in the stored transportable position; such mountings employ extra outrigger supporting wheels and tension cables to keep them parallel.

Granted: 1996-03-26
Abstract: Apparatus and methods for delivering an amount of aerosolized medicine for inspiration by a patient in response to the occurrence of appropriate delivery point or points in the patient's detected breath flow. The aero-sol medication may be administered as one or more pulses having a pulse width, shape, and frequency that will maximize the respirable fraction of the aerosolized compound being administered. The delivery point or points may be predetermined or determined from a prior inspiratory flow for depositing the selected medication at one or more desired locations in the patient's airway. Determined delivery points are recursively lowered for each inspiratory flow that does not satisfy one of the predetermined and previously lowered thresholds. Changes in the patient's breath flow patterns during the course of an aerosolized medication inspiration therapy program may be detected and used to adjust the con-trolled amount of medication to be delivered in a given administration and/or to inform the patient of the pa-tient's condition or change in condition.
