Patent CA-2101647-A1 (CA)
Inventor: LANG VOLKER
IPC: A61M16/00
Filed: 1992-02-18
Abstract: A device for producing a continuous positive pressure in the respiratory passages during spontaneous breathing is described.  Respiratory gas is introduced, under overpressure with modulated pressure oscillations, through nasopharyngeal tubes (9) into the nasopharyngeal-oral cavity (16) or through a special oropharyngeal tube with pressure-measurement channels (flexible tubes) (12, 13) and a wide-lumen gas supply channel (flexible tube) and a narrow-lumen venting channel. In this way, even large leaks in the mouth region can be compensated. To ensure the constancy of the desired therapeutic positive pressures in the nasopharyngeal-oral cavity (16) and the respiratory passages and lungs, which communicate with the nasopharyngeal-oral cavity (16), continuous electrical-electronic measurements are carried out on the pressurized gas by pressure probes (11) in the nasopharyngeal-oral cavity (16), and the supply of fresh respiratory gas is regulated in function of these measurements. Obstruction of the pressure probes (11), e.g., by nasal mucus, is detected immediately by the absence of oscillating pressure signals and any differences in pressure registered by the pressure probes (14, 15), and generally cleared due to the activation of an automatic blow-through device for the probes.  Only in rare cases would an alarm be triggered.

Title: One-piece fitment and cap with tamper-evident band
Inventor: LUCH DANIEL
IPC: B65D55/06
Filed: 1992-10-21
Abstract: A fitment (11) and cap (12) therefor are integrally molded with lugs (51) interconnecting the parts. The fitment has a flange (16) to be attached to a container and an internally threaded spout (19). The cap has an externally threaded skirt (32). The lugs are diametrically spaced and interconnect the bottom edge of the skirt and upper edge of the spout. After molding, force is appli-ed to break the lugs and snap the skirt inside the spout, the threads slipping past each other and interengaging. A tamper-evident band (41) extends around the skirt and is connected thereto by frangible bridges (42). At diametrically spaced locations vertically projecting fingers (48) extend down from the tamper evident band and are received in sockets on the fitment flange shape so that the band fingers prevent unscrewing the cap without removing the tamper-evident band. A pull tab (44) and thumb tab (46) assist the consumer in removing the tamper evident band so that the cap may be unscrewed from the fitment.

Abstract: The present invention is a thin film coating that may be applied to various optical elements and a method for controlling the size of the imaging spot from multiwavelength sources in an optical path. A selective optical element made in accordance with the principles of the present invention comprises an optical surface. Upon the surface, thin film coatings are deposited that define zones of transmission, each zone transmits a desired wavelength band. Beyond this zone, the surface is effectively opaque to a specified wavelength band. The zones for each wavelength are individually calculated to give an effective aperture for each wavelength such that the spot size for all wavelengths meet user specifications.

Title: Three dimensional imaging millimeter wave seeker
Inventor: SCHNEIDER ARTHUR J
IPC: G01S7/41
Filed: 1994-07-13
Abstract: ABSTRACT OF THE DISCLOSURE      An improved imaging system.  The inventive imaging system (10) is adapted to transmit a plurality of first radar signals at millimeter wave frequencies at an area including an object along with background clutter.  The return signals are processed to provide a three dimensional image for applications demanding visibility through fog, haze, smoke and other obscurants.  Such applications include enhanced vision for helicopters, ships, buses, trucks, traffic observation stations for an intelligent highway or security cameras for plants and military  installations.   In  a  guidance  system application, for example, the inventive system would include an electronically scanning antenna (12) to provide range and amplitude signals representative of a target area.  The range and amplitude signals (18, 20) are compared to stored signals (26, 30) to create the three dimensional image.  The stored signals are selected for comparison based on the dive angle of the missile (28, 32). The three dimensional image is then processed (22, 24, 34, 36, 38, 40) to derive guidance commands for the missile.
Patent CA-2127993-A1 (CA)
Inventor: DWINELL DAVIS B
IPC: B65D5/74
Filed: 1993-01-12
Abstract: A two piece plastic nozzle (1) and overlying screw cap closure assembly in combination with a plastic pail cover (15) wherein the nozzle has a cylindrical body portion (5) which is inserted into a cover opening to form a friction fit therewith. The overlying screw cap is then rigidly supported as a sonic welding horn (34) is brought into axial engagement with the protruding nozzle body portion.  Energization of the sonic welding horn causes the nozzle body portion to soften and deform radially outwardly into a circumferentially enlarged rivet connection.  Continued axial displacement of the sonic welding horn creates a plastic bond about the periphery of the rivet connection so as to close off any leakage path therearound.  At the same time any radial dispersion of plastic material resulting from the bonding process is locally contained about the rivet connection periphery.
