Title: Active signalling transmitter control
Inventor: KUZNICKI WILLIAM J
IPC: H04J3/06
Filed: 1989-11-27
Granted: 1993-03-02
Abstract: ABSTRACT      A transmitter (22), having controllable transmission functions is described for transmitting coded message signals to a plurality of portable communications receivers (26), the coded message signals including and message information interleaved with transmitter control signals synchronized with the message information.  The transmitter (22) includes a receiving section (200) for receiving the coded message signals from an input source for transmission.  A decoder (208) which couples to the receiving section (200) decodes the synchronized transmitter control signals to derive transmission control signals.  A transmitter section (206, 216), responsive to the transmission control signals, transmits the coded message signals.  Additional transmission control signals may also be derived from one or more receiver control signals embedded in the coded message signals.

Patent CA-2012696-C (CA)
Inventor: PRESBY HERMAN MELVIN
IPC: G02B6/255
Filed: 1990-03-21
Granted: 1997-12-09
Abstract: This invention concerns with a process and apparatus for fabricating microlenses on optical fibers. A pulsed laser beam and an end portion of a fiber are arranged relative each to another so that the laser beam is incident on the end portion of the fiber at an acute angle .theta. to the longitudinal axis of the fiber. The angle is selected to attain a desired curvature of a lens formed by ablation and heating of the end portion of the fiber by the laser beam. A movement of the fiber and the laser relative each to another results in progressive engagement of the end portion of the fiber with the laser for a preselected distance so as to produce a short taper with a lens at the end thereof. In the preferred embodiment, the fiber rotated about its axis within a passage of the holder which moves the end-portion of the fiber into and through the laser beam resulting in the said lens. The precise repeatability of the lens formation may be controlled by a computer.

Title: Softening agents for recycling asphalt pavement
Inventor: SAWATZKY HENRY
IPC: C08L95/00
Filed: 1991-01-16
Granted: 2002-08-13
Abstract: Methods and compositions are provided for rejuvenating aged asphaltic paving material, or for improving the compatibility of aged asphalt in salvaged old asphalt paving materials with other asphaltic materials, or of improving the resilience to stripping of rejuvenated asphalt and aggregates, by the use of an agent which was heretofore not known to be a rejuvenating agent. Such rejuvenating agent is a sewage sludge-derived oil, or a fraction thereof, having a particularly recited composition. This rejuvenating agent markedly lowers the viscosity of the aged asphalt, disperses the components of the aged asphaltic paving material for dispersion of such, or other added asphaltic components in the asphalt, and increases the adhesion of aged asphaltic paving material to aggregates. Such rejuvenating agent may be used together with other conventional rejuvenating agents and/or softening agents, e.g., hydrocarbon products with physical characteristics which are selected to restore aged asphalt to the requirement of current asphalt specifications, for example, soft virgin asphalts.

Title: Self-cleaning spray nozzle
Inventor: KING WILLIAM J
IPC: B05B1/32
Filed: 1991-07-15
Granted: 1998-10-06
Abstract: A spray nozzle comprises a hollow body having an inlet, an outlet and a fluid flow passage therebetween.  The body contains a pressure-responsive or a pressure responsive and temperature responsive valving element that increases the effective area of the outlet in response to an increase in pressure or an increase in pressure and/or temperature.  In a preferred embodiment, the outlet includes a restricted orifice and an unrestricted orifice, and the valving element is movable within the body between a first position in which the restricted orifice is open and the unrestricted orifice is closed, and a second position in which the unrestricted orifice is open.  The valving element is biased in the first position by a spring which applies a selectable biasing force that defines a threshold pressure, so that the valving element is moved to the second position by a dynamic pressure of the fluid flowing through the flow passage that is greater than the threshold pressure.  In an alternative embodiment, the outlet is provided with a resilient occluder having an orifice that increases in area as the occluder is flexed axially in the downstream direction in response to an increase in the dynamic pressure of the fluid flow.

Title: Removable access panels for rooftop unit
Inventor: SCHARDT DAVID L
IPC: F24F13/20
Filed: 1992-02-21
Granted: 1994-11-29
Abstract: ABSTRACT The present invention is an access panel for a roof top air conditioning unit.  The access panel edges interfit with edges of the air conditioner cabinet to form a tortuous path for entry into the cabinet interior.  The tortuous path inhibits air, water, and moisture penetration. Also, insulating material is trapped between the interfitting edges to further block the penetration and insulate the cabinet interior. At the top edge, a lip extends downwardly to provide a positive stop to keep the removable access panel from laterally falling.

Granted: 2002-01-29
Abstract: In a Code Excited Linear Prediction (CELP) analogue signal coding system sequences from a master codebook (40), which may be a one dimensional codebook, are filtered (42) and then stored in slave codebooks (70, 72). Input analogue signals (20) are filtered (34, 36) and compared orthogonally (66, 78, 80) with sequences from the slave codebooks and an optimum pair of se-quences are selected. Since the comparisons are orthogonal, sequences can be selected from the codebooks (70, 72) and compared (78, 80) with the filtered incoming analogue signals entirely independently.  Reduced length sequences from the master codebook may be compared with orthogonalised analogue signals since orthogonalised signals contain some redundancy. The master code-book may not need to be orthogonalised in some circumstances. Various means of orthogonalisation of the sequences are possible including separation into odd and even sequences. Further orthogonalisations are possible, for example to give four comparisons.

Abstract: Growth hormone releasing hormone (GHRH) receptor binding has been characterized using a unique binding assay utilizing iodinated GHRH probes. Photoaffinity GHRH probes have been constructed which allow for photolabeling and characterization of the receptor. In addition, high affinity biotinylated GHRH analogs have been constructed. Solubilization of GHRH-R/GHRH complexes and extraction of specifically bound GHRH using a mild detergent solution, followed by affinity chromotography, leads to a substantially purified GHRH-R isolate.      Electrophoretic treatment of the GHRH-R isolate produces GHRH-R of sufficient purity to conduct sequencing of the receptor.
