Patent CA-2010144-A1 (CA)
IPC: H04B10/272
Filed: 1990-02-15
Abstract: ABSTRACT      In  a  network  including  an  exchange  having  a masterclock and a number of subscriber stations connected to the exchange the exchange includes a delay line which receives incoming data.   Samples are taken from different taps of the delay line and the tap carrying data in phase with the master clock identified and used to output data. By this arrangement the exchange can immediately lock onto the first pulse of a data cell header even though return data from the subscriber stations exhibits an arbitrary phase relationship with respect to the masterclock.  This enables high speed operation of optical networks at data rates in the region of 150M/bits with circuitry which is cheaper  and  less  complex  than  that  based  on  known techniques.

Title: Vapor sampling probe
Inventor: MCGOWN JAMES B
IPC: G01N1/02
Filed: 1990-04-23
Abstract: Abstract of the Disclosure Disclosed is a portable, hand-held vapor sampling probe for collecting vapors of compounds such as cocaine, heroin, and explosives prior to their desorption and analysis in a vapor detector. Rechargable batteries power a lamp in the front face of the probe for heating target portions of a sampling surface, a puffer assembly for directing air jets at the target, and a motor for drawing air samples through a collector coil on whose surfaces vapors are trapped.  A flexible U-shaped shroud on the front face partially encloses the lamp and collector and helps to regulate air flow over the target and to protect the probe from damage.  Upon contact with a surface, the shroud may activate a switch which, together with a second switch on the probe handle and a lamp pyrometer, regulates heating of the target.

Title: Collagen containing ophthalmic formulation
Inventor: FU CHERNG-CHYI R
IPC: A61K47/42
Filed: 1990-10-12
Abstract: COLLAGEN CONTAINING OPHTHALMIC FORMULATION       ABSTRACT OF THE DISCLOSURE      An ophthalmologically acceptable collagen containing aqueous composition is disclosed.  The composition contains collagen and is a flowable liquid at temperatures below mammalian eye temperature (32°C to 42°C) and forms a gelled sustained release matrix after administration to the mammalian eye.  The composition is comprised of ophthalmologically acceptable collagen material, a pharmaceutically active non-steroidal antiinflammatory drug, optionally an antibiotic, a buffer, a nonionic ethoxylated alkylphenol surfactant, a quaternary ammonium preservative, a tonicifier, a chelating agent, and optional excipients in an aqueous carrier.  The collagen in the composition undergoes a change from a flowable liquid to a gelled matrix after the formulation is administered to the eye.  The gelled matrix of the formulation traps and physically holds the drug in the matrix.  When applied, the gel will remain in place in the cul-de-sac of the eye substantially longer than liquid formulations and will allow for a sustained release method of delivery of the drug to the eye.  The drug release from the matrix and the drug half life are such that the formulation allows for once a day or even less frequent dosing which increases the convenience and improves patient compliance.
Patent CA-2028181-A1 (CA)
IPC: F16F13/00
Filed: 1990-10-22
Abstract: ABSTRACT          A hydraulically dampened rubber bushing includes an outer tube surrounding an inner tube and an elastic body of elastic rubber material which interconnects the tubes and has two chamber pairs which are isolated from each other through a separation wall and each of which includes chambers which are spaced apart in the direction of vibrations transmitted into the rubber bushing.  The chambers of each chamber pair are connected through damping channels.  The damping channels are dimensioned and matched with the total bulge elasticity of all walls of the respectively adjacent chambers, so that the enclosed mass of liquid is induced to resonantly oscillate at different frequencies of vibrations transmitted during applications of the rubber bushing. The separation wall loosely but sealingly engages the outer tube when no vibrations are transmitted and is elastically deformed by the outer sleeve towards the inner sleeve.  The rubber bushing exhibits good damping over a larger frequency range of the transmitted vibrations for extended periods.

Abstract: OPTICAL RANGEFINDER WITH THROUGH THE VIEWFINDER READOUT                  Abstract of the Disclosure A rangefinder includes a housing, an eyepiece, and two spaced optical elements which provide a distance readout by optical triangulation.  A through the viewfinder distance is provided by a distance scale which is mounted on an adjusting shaft for moving one of the optical elements in a pivotal manner relative to the other optical element.  When a remote object is viewed through the eyepiece, two images of the remote object are projected into the eyepiece by the optical elements, and the adjusting shaft is rotated to bring the two images into coincidence.  The angular position of the distance scale can be calibrated relative to the movable optical element by a clutch which disengages the adjusting shaft from the movable optical element to permit the distance scale to be rotated without moving the movable optical element.

Title: Catheter assemblies for prevention of blood leakage
Inventor: HOLDAWAY RICHARD G
IPC: A61M25/06
Filed: 1990-12-14
Abstract: A catheter is provided which deters the backflow of blood between the insertion needle and the catheter cannula by forming the distal end of the catheter hub so as to restrict the inner diameter of the catheter cannula to a wiping fit with the engaged insertion needle. In a first embodiment the distal end of the catheter hub is pre-formed to its desired final inner dimension. The distal end of the hub is stretched to an oversize condition, the catheter cannula is attached to the hub, and the distal end of the catheter hub is heated, causing a stress relief of the previously stretched hub. The distal end of the catheter hub returns to its pre-formed dimension which will mechanically restrict the diameter of the catheter cannula at that point to form the wiping fit with the engaged needle. In a second embodiment the inner diameter of the distal end of the catheter hub is reduced by inserting the distal end of the hub between the opposing faces of a swaging press. which close to compress the hub in one direction. The degree of closure is controlled by the dimension of at least one of a pair of orthogonally opposing swaging press surfaces, which then close to compress the hub in the orthogonal direction. The distal end of the hub is thus swaged to the desired dimension, and the process advantageously produces a finished product without the production of flash material at the intersection points of the swaging surfaces.

Abstract: ABSTRACT OF THE DISCLOSURE   In a wide area cordless telephone system, an individual-call signal is generated if an incoming call from the telephone network is an individual call to one of cordless stations of a group and a group-call signal is generated if it is directed to all cordless stations of the group. A group of access units are associated with the cordless station of each group to establish a control channel and speech channels with the cordless stations. The access units respond to the individual-call signal by transmitting a speech-channel identifier to one of the cordless stations through the control channel and transmitting a ringing signal through a speech channel specified by the speech-channel identifier. In response to the group-call signal, speech-channel identifiers are successively transmitted from the access units to the cordless stations through the control channel and group ringing signals are respectively sent to the cordless stations through speech channels specified by the speech-channel identifiers. In a modified embodiment, the cordless stations receive pairing identifiers each containing a pair of an access unit identifier and a cordless station identifier and transmit a response containing one pairing identifier that specifies the own station. The access units also receive pairing identifiers from the controller for detecting a match with those received from the cordless stations. If a match is detected by each access unit, it is entitled to send a speech-channel identifier to the cordless station which is specified by the matched identifiers.
