Title: Lipospheres for controlled delivery of substances
Inventor: DOMB ABRAHAM J
IPC: A61K9/50
Filed: 1990-11-08
Abstract: Solid, water-insoluble lipospheres formed of a solid hydrophobic core having a layer of a phospholipid embedded on the surface of the core, containing biologically active agent in the core, in the phospholipid, adhered to the phospholipid, or a combination thereof, are disclosed for use in providing extended release of active agent, including drugs such as vaccines and anesthetics, insect control agents such as insecticides and repellents, and agricultural compounds such as fertilizers, fungicides, pesticides, and herbicides. Lipospheres can be prepared by a melt technique or a solvent technique, summarized as: (1) forming a liquid solution or suspension of the agent by either melting the agent, or dissolving or dispersing the agent in a liquid vehicle, to form a mixture of liquid agent that solidifies at room temperature or greater; (2) adding phospholipid and an aqueous solution to the liquid agent to form a suspension; (3) mixing the suspension at a temperature above the melting temperature until a homogeneous fine dispersion is obtained; and then (4) rapidly cooling the dispersion to below the melting temperature of the liquid mixture containing the agent. Agent can also be added to the phospholipid or mixed with the resulting lipospheres. The agent containing lipospheres have several advantages over other delivery systems, including emulsions, vesicles and liposomes, including stability, low cost of reagents, ease of manufacture, high dispersibility in an aqueous medium, a release rate for the entrapped substance that is controlled by the phospholipid coating and the carrier. Examples demonstrate the effective administration of anesthetics, antigens, and insect repellent (DEET).

Title: Multiple output referencing system for evanescent wave sensor
Inventor: COOK THOMAS A
IPC: G01N21/64
Filed: 1992-05-26
Abstract: ABSTRACT    An evanescent wave system and method including an optical sensor for use in assaying a reference material and at least one molecular species or analyte in a test medium or test sample for diagnostic and other applicable purposes. The sensor includes a waveguide for propagating a radiation input along its length.  The radiation input causes evanescent electromagnetic waves that are capable of stimulating output emissions that are indicative of a reference material and of one or more molecular species or analytes. By comparing the emission(s) indicative of the reference material to the emission indicative of the presence of the molecular species or analyte, the presence and concentration of the molecule in the sample can be determined.  The reference material provides for normalization and/or calibration of the system.

Abstract: A pitch control mechanism for a ram air turbine blade (4) comprises a mass (1) fixed to the blade shank (2) in a plane at an angle, to a pitch change axis (5). As the turbine rotates about the rotational axis 7, the mass (1) moves in the direction of arrows (11, 12) according to the speed of rotation varying the pitch of the blade (4). By directly coupling the pitch change mass (1) to the blade (4) the need for complicated linkages is eliminated.

Title: Process and apparatus for the termination of electric cables installed in a building for subsequent connection
Inventor: LALOUM LAURENT
IPC: H01R9/24
Filed: 1993-03-26
Abstract: DESCRIPTIVE ABSTRACT            The process for the termination of electric cables (2) makes it possible, during the installation of the electric structure of a building, to prepare the final connection of each cable (2) by any random operator.  Use is made of standardized cable termination means for provisionally storing the cable ends.            The apparatus essentially comprises a block (1) within which is inserted, for each cable (2), a locking part (3) having a flexible tongue (5).  The introduction of a cable (2) into its recess (7) is definitive as a result of the locking action of the tongue (5).  The final connection takes place by means of a connecting hole (8) traversing the recess (7).  It is therefore possible to prepare the connection of numerous cables with numerous electrical equipments to be supplied.            (fig. 1)
Patent CA-2093849-A1 (CA)
Inventor: ENG KAI Y
IPC: H04L12/56
Filed: 1993-04-13
Abstract: Significant throughput improvement is achieved for an input queued packet switch using output port schedulers by permitting the output schedulers to recycle or reassign cell transmission times from input ports which are unable to use them. When an output scheduler assigns a cell transmission time to an input port and that input port is unable to use the assigned transmission time due to a scheduling conflict, for example, the input port makes a new request for the same output port during the next subsequent request period and then returns the unable transmission time assignment back to the output scheduler. The output scheduler stores the returned transmission time in a separate queue for assignment to later requests for the particular output port. Throughput performance is improved from 58% (without time slot recycling) to 92% (with time slot recycling) for random packet cell trafficmodels,

IPC: B60C23/02
Filed: 1992-09-11
Abstract: SELF-REGULATING TIRE PRESSURE SYSTEM AND METHOD           ABSTRACT OF THE DISCLOSURE      A self-regulating tire pressure system and method em-ploys a bistable valve (10) that allows air from a high pressure reservoir (6) to replenish the pressure within a tire (4) when it has fallen below an actuating pressure, and discontinues its operation only after the tire pressure has increased to a closing pressure that is greater than the actuating pressure.  The system is capable of sensing the valve's (10) frequency of operation as an indication of a slow tire leak when the frequency exceeds a predetermined threshold, of sensing the number of valve (10) operations and the duration of each operation as an indication of a flat tire condition when the number of operations for a predetermined duration exceeds a second threshold, and of sensing the duration of the valve's (10) operation as an indication of a low reservoir (6) pressure condition when that duration exceeds a third threshold.  The valve (10) includes a bistable diaphragm (94, 120) that receives a reference pressure on one side and the tire pressure on its opposite side, and snaps between two stable positions re-spectively opening and closing the valve (10) in response to the tire pressure falling below the actuating pressure and then increasing to the closing pressure.

Abstract: A locking/release mechanism for a pivot bolt of a closed-circuit door opener with a safety catch for the pivot bolt is controlled by an electromagnet. In order to reliably ensure a release of the pivot bolt, even if strong pressure has been exerted thereon prior to the cessation or interruption of the magnet current, a locking lever is positioned between the electromagnet and the safety catch. The locking lever has a two-armed construction, one arm being provided with a stop member for engagement with the safety catch and the other arm being in the form of the electromagnet armature. The effective contact surface between the safety catch and the stop member is constructed in such a way that the safety catch applies a cam-like displacement action on the stop member.

Abstract: Sealed bearing roller cone rock bits are prone to seal wear and failure due to the encroachment of abrasive drill cuttings into the seal gland. A hard metal cuttings diverter pad angularly positioned across the bit leg backface, adjacent the trailing edge of the leg shirttail edge relative to cone rotation, wipes the accumulated drill cuttings from the rotating cone backface. A circumferential groove, formed in the bit leg backface, promotes a relatively high volume flow of drilling fluid at the seal gland entrance to flush away the abrasive cutting particles not diverted by the hard metal diverter pad.
