Title: High density connector arrangement for a circuit board module
Inventor: SELFRIDGE RITCH ALLEN
IPC: H01R12/52
Filed: 1998-01-13
Abstract: A circuit board module includes a plurality of high density edge connectors (11, 12) in which the contacts are arranged in rows, with contact tails (13) extending from the connectors (11, 12) for electrical connection to a circuit board (8, 9) carrying electrical components.  Instead of terminating the contacts directly to pads or terminals on the principal surface of the circuit board on which the electrical components are situated, the contact tails are terminated to pads or terminals on pairs of intermediate circuit boards (14, 15) each providing two termination surfaces rather than one, thereby effectively doubling the space available for termination. The intermediate circuit boards (14, 15) are connected to the main circuit board (8, 9) by a rigid-flex interconnection,(16, 17) thus facilitating assembly of the connectors to a heat sink (10) or frame of the circuit board following termination of the contact tails to the intermediate circuit boards.

Patent CA-2254586-A1 (CA)
Inventor: SKUSE THOMAS P
IPC: B27G11/00
Filed: 1998-11-27
Abstract: In accordance with one specific, exemplary embodiment of the invention, there isprovided an apparatus for continuously processing a wood product formed from lengths of wood strips assembled in face-to-face, laminated relationship with heat curable adhesive applied to adjacent contacting faces of the strips. The apparatus includes a continuous press comprising confronting members defining between them an elongated press zone extending in a longitudinal direction. The confronting members are adapted to apply pressure to the wood product in a transverse direction substantially normal to the faces of the assembled strips while advancing the wood product through the press zone. The apparatus further includes first and second parallel electrodes coextensive with at least a portion of the press zone, the first and second electrodes being separated by an interelectrode spacing and defining between them a curing zone. The first electrode is connectable to a source of RF energy and the second electrode is connectable to ground potential. To provide the required isolation of the RF field and prevent arcing and other losses of RF energy, the interelectrode spacing is less than the distance between the first electrode and any adjacent metallic members. The confronting members of the continuous press comprise first and second linear arrays of blocks made of electrically insulative material, each block having a first or front face adapted to engage the wood product, and a second or rear face opposite the first face. Drive elements, preferably in the form of the links of a steel chain, are coupled to the second faces of the blocks and are driven so as to move the linear arrays of blocks along the press zone. The blocks are disposed in side-by-side relationship with the sides of adjacent blocks in close proximity so that uniform pressure is applied across the laminated wood product along the entire length of the press zone so as to prevent localized separations from forming between laminations. In accordance with another aspect of the invention, there is provided a wooden pallet having parallel ends, parallel sides, a top deck for receiving a load and a bottom deck parallel with the top deck. The pallet further includes at least two continuous stringers between the top and bottom decks to maintain said decks in spaced relationship, the stringers extending longitudinally between the ends of the pallet and wherein each 22. stringer is constructed of continuous wood stock assembled from face laminated, glued scrap wood strips of random length. In accordance with another aspect of the present invention, at least one of the decks comprises a plurality of parallel, spaced apart boards extending transversely between the sides of the pallet and wherein each board is constructed of wood stock assembled from face laminated glued scrap wood strips of random length.

Inventor: TIMMONS HENRY D
IPC: F23L17/04
Filed: 1999-01-28
Abstract: A ventilation system for urging flue gases from an exhaust source through an exhaust conduit has an exhaust outlet for venting the gases and an exhaust inlet communicating with the exhaust source. A blower fan is provided for creating a positive air flow away from the exhaust inlet to urge the flue gases through the exhaust conduit and out of the exhaust outlet. A blower pipe channels air from the blower fan into the exhaust conduit past the exhaust inlet so as to create a venturi effect to draw exhaust from the exhaust inlet into the exhaust conduit. Duct work may be provided so that the blower fan draws fresh air from the ambient, namely from outside the structure housing the exhaust sources, rather than from inside the structure.

Title: Operation for processing piece goods as well as control process and facility for carrying out the processing operation
Inventor: REIST WALTER
IPC: H05K13/08
Filed: 1997-07-16
Abstract: The claimed processing operation is used to process piece goods. Large numbers of at least similar objects are processed by feeding objects into the operation in streams (PS) of starting products (A), feeding the starting products and/or intermediate products in product streams (PS) to processing steps (7, 8, 12, 14, 15...) where they are processed and then carried away from the processing steps, and discharging the processed objects from the operation in streams of end products (EP). In the incoming and outgoing product streams individual products or product groups are conveyed in a sequence. At each processing step at least one property of a processed product or product group is changed. The claimed operation is charaterized by sequence changes (4, 5, 6, 10, 13, 16, 17...) in which the sequence of products or product groups can be changed by transferring products in or out or combinations of both. As a result, the processing steps can be linked to any degree of complexity and nevertheless the operation can be carried out with great flexibility. Sequence changes as well as at least some of the processing steps can then be controlled according to relevant properties of the incoming products or product groups and/or according to a predetermined sequence to be established.

Title: Covalent polar lipid conjugates for targeting
Inventor: YATVIN MILTON B
IPC: C07H19/10
Filed: 1997-10-27
Abstract: This invention herein describes a method of facilitating the entry of drugs into cells and tissues at physiologically protected sites at pharmicokinetically useful levels and also a method of targeting drugs to specific organelles within the cell. This polar lipid/drug conjugate targeting invention embodies an advance over other drug targeting methods known in the prior art, because the invention provides drug concentrations in such physiologically protected sites that can reach therapeutically-effective levels after administration of systemic levels much lower than are currently administered to achieve a therapeutic dose. This technology is appropriate for use with psychotropic, neurotropic and neurological drugs, agents and compounds, for rapid and efficient introduction of such agents across the blood-brain barrier. Further, the invention provides means for retention and prolonged enzymatic release of psychotropic, neurotropic and neurological drugs, agents and compounds comprising the conjugates of the invention, in the brain and central nervous system.

Title: Piezo-electric zpe coupled motor
Inventor: LAGACE GERALD
IPC: H01L41/09
Filed: 1999-06-17
Abstract: There has in recent years been a great surge of new theories on the nature of the space time plenum or the quantum mechanical vacuum. Many papers have been written and published describing the properties of space time when linear dimensions of sub-atomic scales are approached in the order of 10 -33cm. This domain is known as the Zero Point Energy Plenum and current theory suggests that the familiar co-ordinated of our space times X2+ Y2+ Z2- ct2= 0. do not exist at this Planck length. In this domains particle wave duality demonstrates itself in that any wave approaching 10 -33cm. in dimensions would behave as a particle with finite mass. inertia. and even electric charge. This domain would be consistent with the relations ct2- X2- Y2- Z2= 0.
