Inventor: SYDOR ROBIN M
IPC: A61F5/02
Filed: 1993-09-17
Abstract: A support stay for use with an article to be worn by a person has two durometers of hardness.  The support stay includes a base member having a first hardness, the first hardness sufficient to provide a required rigidity for support.  A gripping member is operatively connected to the base member and has attachment areas which extend beyond the ends of the base member.  The gripping member has a second hardness which is softer than the first hardness.  The gripping member, when attached to the inner surface of the article by attachment areas, provides a non-slip surface against the person wearing the article to keep the article in position.

Filed: 1992-05-27
Abstract: Laminar flow of air in a boundary layer adjacent a face of an aircraft component exposed to air flow over it has been controlled by injecting air into the boundary layer or by withdrawing air from it through a multitude of small holes drilled through the component. To avoid the disadvantages of drilling holes a low drag component (12) is provided which includes a cellular face region (13) which includes a front face (15) exposed to air flow and which has an open celled structure which permits gaseous fluid flow through the face (15) of the component (12). Manifolds (41) are provided at the rear of the face region (13) to permit or cause gaseous fluid flow from or to the boundary layer through the open celled structure of the face region. In one form, the face region is made from a porous permeable thermoplastics material by powder sintering the thermoplastics material.

Abstract: A process for improved dewatering and retention in the production of paper, where an anionic retention agent based on starches, cellulose derivatives or guar gums having no cationic groups and an acidic solution of an aluminium compound are added to the stock containing lignocellulose-containing fibres and optionally fillers. The pH of the stock prior to the addition of the aluminium compound should be at least about 6 to obtain the desired cationic aluminium hydroxide complexes in the stock. The present process is cost effective and insensitive to the content of calcium in the white water.

Abstract: A hydraulic system for a vehicle adapted for operating a plurality of reel mower cutting units and for driving at least one vehicle component such as drive wheels or power steering. The vehicle carries an engine near the front of the vehicle which generates heat.  The system includs a fluid reservoir located remote from the engine and near the rear of the vehicle. An input line is coupled with the reservoir, and a first pump is operatively coupled with the input line.  A first motor receives fluid from the first pump for driving a reel mower, and a branched line having first and second branches receives fluid from the first motor.  The first branch is a first return line extending to the reservoir. A second pump having a lower capacity than the first pump is operatively coupled with the second branch, and a second motor receives fluid from the second pump for driving the vehicle component.  A second return line receives fluid from the second motor and is coupled with the input line for allowing fluid from the second motor to flow to the first pump without first flowing to the reservoir.

Patent CA-2111964-A1 (CA)
Inventor: HEIT MARTIN A
IPC: B65G13/071
Filed: 1992-07-02
Abstract: A zero-pressure accumulating conveyor including a bed defined by rotatable rollers mounted in parallel sidewalls and powered by an endless chain. Pneumatic actuators lift the drive chain into engagement with the rollers to empower same.      Sensor rollers divide the bed into distinct zones. Sensor rollers are retained in operative position relative to the conveyor bed by unique sensor brackets. A primary sensor roller bracket includes a bore with a piston movable therewithin; the cooperating secondary sensor roller bracket is spring biased in a first direction. Valves and pneumatic circuitry controlled by such valves, extend along the length of the conveyor. Such valves are operated by the primary sensor roller brackets to regulate the flow of air pressure into the bores of the brackets and into the actuators. The actuators, when the pressure therein is bled-off, allow the chain in a particular zone to drop out of contact with the rotatable rollers. When the bore in the primary sensor roller bracket is pressurized, the bracket moves in an arc that forces the sensor roller below the plane of the conveyor. In such position, the sensor roller is not actuated as items travel thereover, and the life of the accumulating conveyor is significantly extended.

IPC: H04L29/08
Filed: 1994-01-31
Abstract: A method and apparatus for intermixing circuit and packet data on a shared transmission medium.   With this invention, the history of gaps between transmitted circuit frames is used to predict future gap sizes.  If the size of a predicted gap is larger than the size of a frame of packet data to be transmitted,  then the packet data is inserted in the next gap.  If a circuit data frame arrives before the completion of transmission of a packet frame, the circuit data will be stored in an insertion buffer until completion of transmission of the packet frame.

Title: Video imaging method and apparatus for audience participation
Inventor: CARPENTER LOREN C
IPC: H04H60/31
Filed: 1992-12-09
Abstract: An audience response system in which each audience member is provided with a reflective device (44) (or other radiation source) which is, for example, green on one side and red on the other side.  Light from a spotlight (40) is reflected from the reflectors (44) and imaged by a conventional video camera (24). A computer (14) receives the digitized and processed image, forms a map of the audience, and distinguishes the red from the green reflections.  This data is then used by the computer (14) to project an image onto a screen (34) visible to the audience, the image being controlled by the red or green image reflections. The audience thus jointly controls the screen image, for instance for purposes of voting or playing a game. The system also can detect movement (direction and/or velocity) of each radiation source which data is aggregated and thereby manipulates the screen image. Also, the sources each may transmit coded information (such as Morse code or ASCII) to individually identify themselves.

Filed: 1994-08-30
Abstract: A material handling system which is transportable to a drilling site includes all of the equipment necessary for preparing high-ratio mixtures of composite materials at the site.  The system has a housing which capable of being loaded on a vehicle and within which are mounted a row of material dispensers, a number of filled material bags which are ready to be loaded on the dispensers, and a conveyor arrangement for collecting material from the dispensers and discharging it through a directed downspout from one end of the housing.  The dispensers each have an auger mechanism that has one of three selectable diameters, and also have a variable gear arrangement allowing an auger of the auger mechanism to rotate at a selectable speed.   The material handling system has a control system which is capable of identifying the material loaded on each dispenser, and of determining the length of time that the auger associated with each dispenser must operate to produce a material of selected composition.  Using differences in auger diameter, auger rotational speed and duration of auger activity, the material handling system is capable of accurately creating mixtures in which the ratios of the ingredients can have a wide variation.

Title: Using sub-threshold unipolar pacing markers to improve the interpretation of surface ekg in pacemaker patient
Inventor: SPINELLI JULIO C
IPC: A61N1/37
Filed: 1994-10-05
Abstract: A pacemaker including a marker code generator generating marker codes between an indifferent electrode disposed on the pacemaker housing and the pacemaker can serving as a reference electrode. Marker code signals are generated proximate the pacemaker rather than proximate cardiac tissue, and thus can be generated at a large potential for sensing by surface EKG, and can also be generated simultaneously while pacing the heart and not necessarily in the refractory period. The pacemaker facilitates the interpretation of surface EKG, and can be sensed and recorded by commercially available two-channel holter monitors which can be taken home with the patient.      Thus, marker code signals can be sensed and recorded while at home and played back for the physician at a later time for analysis. The marker code generator can be selectively turned on by the external programmer such that battery life depreciation is not appreciable. The pacemaker can be adapted with either a unipolar or bipolar endocardial lead.
