Title: Detachable Pusher-Vasoocclusive Coil Assembly with Interlocking Ball and Keyway Coupling
Inventor: ENGELSON ERIK T
IPC: A61M25/14
Filed: 1992-12-08
Abstract: A pusher-vasoocclusive coil assembly that is advanced through a catheter to a site within a vessel and is manipulated to detach the coil from the assembly.  The coil has an enlarged member at its proximal end and the pusher has a keyway at its distal end that receives the enlarged member in interlocking engagement.  The pusher and coil are coupled by placing the enlarged member in the keyway and enclosing the coupled assembly with a coaxial sleeve.  The coil-pusher-sleeve assembly is positioned at the site and the sleeve is retracted to allow the member to move out of the keyway to uncouple the pusher and coil.

Title: Process and device for producing a plastic container and having an envelope sheet suction holding mandrel
Inventor: DOEBLER WALTER
IPC: B29C49/24
Filed: 1992-03-18
Abstract: A process and device for producing plastic containers, e.g. by injection or blow moulding, in which the process for making the plastic containers features an envelope sheet (8) in the form of a label integrated into said containers by the in-mould labelling process. To this end, a moulding tool has a mould and can be closed or opened, and molten plastic may be introduced therein via an aperture. An envelope sheet (8) is introduced into the mould (2) before the injection mould is closed by conveying it between two conveyor belts (21, 22) against a stop edge (15) of a suction holding mandrel (4) where the leading edge of the envelope sheet is pulled in via first depression apertures (16) and the suction holding mandrel (4) is then rotated, thus winding the envelope sheet (8) upon it. Via second depression apertures (19) distributed about the periphery, the envelope sheet (8) is held in the wound condition by the suction holding mandrel (4) over its entire length.  When the moulding tool then opens, the suction holding mandrel (4) is swung into an intermediate space thus formed and transferred to the mould (2).

Patent CA-2135147-A1 (CA)
Inventor: NICOLAY ALBERT
IPC: B29C45/00
Filed: 1994-11-04
Abstract: The invention relates to a method for the production of laminated mouldings, such as internal linings or panellings of motor vehicles and the like, dimensionally stable parts, in which a support part is provided with a surface lamination and in which initially a preform having the same volume as the support part, but not having the same surface area with respect to the final shaping is produced. Utilizing the production heat inherent in it, the said preform is then connected by pressure action to the lamination by back-embossing with the thermoplastic material of the support part and is given its final shape by material flow processes.            The invention is intended to improve back-embossing in the production of laminated mouldings in such a way that with reduced embossing forces the surface-unitary adhesion of the lamination to the support part is improved and in particular for this the risk of bubble formation must be eliminated.  This is achieved in that preforms identical as regards volume to that of the support part and having same contour shapes as the finished laminated moulding and with a lattice-like structure at least in partial areas are subject to the material flow process, so that the initially open lattice meshes of the preform are closed by local flow with the pressure application for the back-embossing process.

Title: Data analysis method for use with fluorescent bacterial sensors
Inventor: BERNDT KLAUS W
IPC: G01N33/483
Filed: 1995-01-19
Abstract: A method of analyzing the data provided by a fluorescent chemical sensor calculates a ratio based on the AC and DC components of the emission from the chemical sensor. This ratio, or the emission modulation, will change should bacterial growth be ongoing in the vial. The calculated ratio is compared to a desired value. The desired value is selected to focus the operation of the system into a high resolution area for the sensor. If the calculated and desired ratios differ, then the frequency of the excitation radiation is changed until the calculated and desired ratios are effectively equal. At that time the adjusted frequency is measured. By focusing the desired ratio into a high resolution area, and adjusting the frequency until the system reaches that ratio one ensures that all readings are performed at a high resolution area of the sensor. The adjusted frequency is utilized to provide an indication of whether the particular vial is experiencing bacterial growth. This adjusted frequency is a linear function of changing conditions within the vial. Several methods of achieving the above features of this invention are disclosed. By utilizing this method, one provides an easily interpreted indication of whether a particular fluorescent chemical sensor is in a vial which is experiencing bacterial growth.

Patent CA-2152781-A1 (CA)
Inventor: PETRANOVICH JAMES E
IPC: H04L27/227
Filed: 1993-12-30
Abstract: A PSK signal is received and digitized in a limiter (26) to substantially remove the signal's amplitude characteristics. A phase detector (44) receives the digital data and, based upon transitions in the data between high and low states, provides phase estimates. The phase estimates are converted by a data decoder (50) into binary data representing the symbols transmitted to form the PSK signal. A number of overlapping windows of digital data are used to determine phase estimates.  A unique word detector (52) receives binary data from the data decoder (50) and, using a correlation technique, identifies one set of windows which substantially maximizes synchronization of the demodulator with the received PSK signal. After the synchronizing window has been identified, an automatic frequency controller (46) monitors any frequency drift of the PSK signal and corrects the phase estimates.
