Patent CA-2092300-C (CA)
Title: Monocontrol venetian blind
Inventor: RUDE EDWARD T
IPC: E06B9/322
Filed: 1992-07-23
Granted: 1996-04-02
Abstract: Headrail hardware to lift and tilt a Venetian blind is provided. A single control (5) operates both the lift and the tilt func-tion. A multiturn band brake tilter (19) is used with each ladder cord (15) in a way that reduces the frictional forces encountered in lifting or lowering the blind. One end of each of the ladder cords is attached to an arm (21) of its tilter. The tilters are disposed directly about the rotating drive rod (11) with no intermediate parts, and are supported by cradles (17) that mount in the headrail rather than by the drive rod (11) as in prior art blinds. The drive rod (11) rotates the tilters (19) and the lifting mechanism until the tilters (19) contact stops built into each of the cradles (17). Further rotation keeps the blind fully tilted while lifting or lowering of the blind continues. In the preferred embodiment, the lift cords (13) are attached to the drive rod (11), which traverses to accumu-late the cords (13) in a single layer as the rod (11) is rotated to lift the blind. The rotation of the rod (11) within the tilters (19) greatly reduces the lateral force needed to traverse the rod (11). An innovative bearing support (41) is provided so that the weight of the blind is transferred from the tilter (19) directly to the cradle (17), further reducing the frictional drag on the traversing rod (11).

Title: Energy dissipation resistor for implantable defibrillation circuitry
Inventor: O'PHELAN MICHAEL
IPC: H05K1/16
Filed: 1993-05-05
Granted: 1997-03-25
Abstract: An energy dissipation resistor for dissipating electrical energy stored in implantable defibrillation capacitor(s).   The resistor comprises a layer of resistive foil sandwiched between two layers of electrically insulative material so as to define a circuitous resistive path.  At least two electrically conductive contacts are disposed through one of the insulative layers such that each of the contacts provides an electrically conductive path from the  exterior of the energy dissipation resistor to the resistive  foil  layer enclosed therein.   Conductive leads are electrically connected to the conductive contacts and provide a means by which the energy dissipation resistor can be connected to defibrillation circuitry.  The energy dissipation resistor can also be formed integrally with a flexible circuit board, a rigid circuit board, a circuitry liner, or a hybrid substrate.

Abstract: A transport apparatus for a weighing module includes a scale which has a deck connected to a scale base for weighing an object placed on the deck. The deck has slots for accommodating dual thickness belts which are arranged below the deck to be in substantial registration with the slots. The belts are positioned with respect to the slot such that in a home position a thinner section of the belt does not protrude through the slot whereby the transport means does not interfere with weighing of the object on the deck. When the belts are actuated, the dual thickness belts move so that a thicker section of each belt protrudes through the slot as the belts are being driven to thereby lift the object from the deck onto the thicker section of the belt to transport the object on the belt. In order to provide a safety factor in the event that something is caught in the belts in order to detect problems in the operation of the belts, the belts are monitored using a photodetector for measuring the actual travel time of the belt and comparing it to an expected time. The detector makes use of the slots in the belt to check the transitions between slot and tooth.

Abstract: A  device  for  implanting  endoprostheses  (1)  has basically a tubular outer body (2) and an elongated core element (3) placed inside of this. To operate the device, both the core element (3) and the tubular body (2) are provided with handles (5, 6) at their proximal ends.  In order to produce a form-locking connection between the endoprosthesis  (1)  and the core element  (3),  the core element (3) exhibits a region (10) in which is impressed a relief corresponding to the inner form of the endoprosthesis (1).  As a result of this, there are a great number of form- locking  meshing  sites  between  the  enclosed,  folded endoprosthesis (1) and the core element (3).  A device with this   type of   design   permits   partially   released endoprostheses (1) to be folded back up again by pushing the tubular body (2) forward so that the endoprosthesis (1) may be repositioned.  In addition, sure and reliable operation is achieved by this type of stamping of the core element (3).

Abstract: The bidirectional clocking apparatus provides automatic sensing of whether a reference clock being generated by another circuit needs to be divided down to a lower frequency. If this is true, the clock is divided down to a lower frequency and sent out to other circuits requiring the lower frequency clock. If the lower frequency clock is already generated from another circuit, the apparatus accepts this clock for use by other circuits. Only one terminal is required for either sourcing or accepting this lower frequency clock signal.

Abstract: A computer method and storage structure for storing and accessing multidimensional data is provided. A tree manager provided by the present invention stores data such as pointers, variable length data records, other B-trees, and directories, in a Multidimensional B-tree (MDB-tree). An MDB-tree has an imbedded "parent-child" structure which allows subtrees to be stored within nodes. The subtrees contain subnodes, which, in turn, may contain subtrees. The nodes are indexed by a primary key value while the subnodes in a subtree are indexed by secondary key values. Nodes of a MDB-tree contain a key value table, a subnode table, and a data area. When the tree manager attempts to store a unit of data on a page and the unit of data is too large for the page, the tree manager attempts to split a node currently stored on the page (or the unit of data being inserted) into a subnode and a subtree. The subtree is then stored on a new page. If the unit of data cannot be split into a subnode and a subtree, then one or more of the node currently stored on the page are moved to a new page.

Title: Process for reducing sludge accumulation in the hot water extraction process for oil sands
Inventor: SCHUTTE ROBERT
IPC: C09K23/54
Filed: 1994-11-01
Granted: 1998-09-22
Abstract: A dispersant, such as sodium silicate, is added to the process water of the hot water extraction process which recovers bitumen from oil sands. The dispersant disperses the ultrafine (less than 300 nm) particles, to reduce the formation of flocs and sludge in the tailings pond. The volume of the pond is such that the retention time of process water is sufficiently short (less than 6 weeks when using sodium silicate) to avoid reforming flocs from the dispersed ultrafines. The ultrafines content in the process water builds up as the water is repeatedly recycled from the pond to the extraction process. The ultrafines content stabilizes at a steady state level as some ultrafines are continuously removed from the water supply when the tailings are delivered onto the "beach" of the pond and become trapped in the sand.

Abstract: A power management architecture in a data processing system comprising physical devices having at least one state, each state has corresponding power value, and where a system state is defined as the set of all current states of the physical devices. Power objects and thermal objects, each corresponding to a physical device, contain information about the power requirements and thermal characteristics of each possible state for that physical device. The power and thermal objects also describe the allowed state transitions from each possible state to another state, and the power requirements and thermal characteristics of all possible state transitions. Also communicated is the current state of each physical device. Event means generate signals indicating the occurrence of an event in the system. A policy module contains rules, implementing the power management, that direct an action, the rules being a function of events and of power object information. A controller, in communication with the physical devices, the thermal and power objects, the event means, and the policy module, changes the state of any one of the physical devices in response to an event. The controller determines whether to change a physical device state based on the policy module rules.
