Patent CA-2119402-A1 (CA)
Inventor: FORD MICHEAL E
IPC: C08F26/00
Filed: 1994-03-18
Abstract: ABSTRACT     Amine functional polymers which are terpolymers made up of randomly linked units of amidine or amidinium formate, N-vinylformamide and either vinylamine or vinylammonium formate are prepared by aqueous hydrolysis of poly(N-vinylformamide) at a temperature in the range of 90 to 175°C, preferably in the presence of a minor amount of ammonia or volatile amine. Best conversions and good control of polymer structure are obtained at 140 to 160°C with a small concentration of ammonia or alkylamine. Formation of poly(vinylammonium formate) containing no other salts or ionic coproducts is realized by degassing the hydrolyzate to remove ammonia or amine from the polymer solution.  The poly(vinylammonium formate) affords distinct advantages in the production of salt-free polymers by catalytic decomposition of impurities.  Poly(vinylamines) containing significant amounts of amidine functionality offer advantages in applications where increased basicity is required.

IPC: H01T7/00
Filed: 1993-08-20
Abstract: ABSTRACT            By conducting a polyphase AC in the order of phase sequence to the discharge electrodes forming a regular polygon, because electric discharges are generated as they rotate continuously at a high speed covering the region surrounded by the plurality of electrodes, a highly intensive energy accompanying various discharge phenomena such as intense heat or highly  intense  light can be generated very efficiently, and because these discharges occur in a virtual plane form,  utilization of the highly intensive energy accompanying the discharges becomes very easy.  A melt processing of powder waste can be efficiently done by utilizing virtual plane arc discharge generated by a polyphase AC multielectrode discharge apparatus, and ozone can be very efficiently generated by utilizing virtual plane corona discharge generated by a polyphase AC multielectrode discharge apparatus, and further by utilizing virtual plane discharge generated by the polyphase AC multielectrode discharge apparatus, a light source apparatus in which the whole discharge chamber lights uniformly can be provided.

Title: Device and method for adaptively adjusting loading capacity for a node in a packetized communication system
Inventor: PFEIL JEFF
IPC: H04L12/54
Filed: 1993-11-18
Abstract: Flow of digitized coded speech packets through virtual circuits in a multi-node communication system (300) is controlled by an adaptive loading capacity device (102) in the nodes (314, 316, 318).  The adaptive loading capacity device (102) determines an adjusted throughput data rate ATDR (602, 604) for a node (314, 316, 318) that is substantially equivalent to a predetermined upper limit of the system's capacity. When a requested data rate value RDR  included in a frame (200) is greater than the ATDR, the device automatically adjusts the RDR downward to substantially equal the ATDR (702, 704) and incorporates the adjusted RDR into frames (200) transmitted to coupled nodes (314, 316, 318) and stations (302, 308).

Title: Folding bed assembly for use within an article of furniture
Inventor: POKORNY L ROBERT
IPC: A47C17/58
Filed: 1994-12-13
Abstract: A folding bed assembly for use within an article of furniture, such as a desk, having a fixed top wall.  A series of bed sections, pivoted to one another in succession, are foldable into a generally rectangular collapsed condition in which the longer dimension of the rectangle is oriented vertically when the folded sections are within the article of furniture.  The bed sections are mounted on a wheeled carriage, and a vertical panel hides the bed assembly when it is within the article of furniture.  A carriage linkage responds to pivoting of the panel from its vertical orientation to a horizontal orientation for moving the carriage and bed sections out of the article of furniture.  A swing-out linkage pivotally supports the collapsed bed sections on the carriage, the swing-out linkage constraining the collapsed bed sections to move between a storage position, in which the collapsed bed sections are close to the carriage, and a swing-out position in which the collapsed bed sections are elevated above the carriage.  The swing-out linkage rotates the collapsed bed sections, between the storage and swung out positions, so that the longer dimension of the rectangle moves from a vertical orientation, in the storage position, to a horizontal orientation, in the swing-out position.

Title: Device for removing dust particles from exhaust gases
Inventor: KWETKUS ANDREAS
IPC: B03C3/30
Filed: 1994-12-14
Abstract: The  device  for removing dust particles  from exhaust gases has a fabric filter  (2)  arranged in a filter housing (1). A precharger (4) installed in the exhaust gas line (3) upstream of the filter housing (1) serves to charge the dust particles before the latter reach the  fabric  filter  (2).  The precharger  (4)  is designed as  an independent unit.  The precharger  (4) comprises at least two grid-shaped electrodes  (8,  9) which   extend   relative   to   one   another   in   an approximately plane-parallel  fashion  and are  aligned transverse to the exhaust gas flow. The electrodes are connected to a high-voltage source  (12)  which is at earth potential on one side.        Owing to these measures, the dust particles are optimally precharged and because of their charge are precipitated on the fabric filter as a loose, porous and therefore gas-permeable layer, without the need for additional electric fields to be present there.        Because of the high rates of flow prevailing in the  exhaust  gas  line  upstream  of  the  filter,  the placement  there  renders  a  knocker  and  cleaner dis-pensible in the precharger.

Abstract: Apparatus for indicating material level that includes a pair of ultrasonic transducers on opposed sides of a space for receiving the material at the level to be detected.  A swept frequency oscillator is coupled to one of the transducers so that the transducer radiates into the material space ultrasonic energy that continuously sweeps back and forth between a low frequency range at which such energy is transmitted to the other transducer by resonance of the entire apparatus and independent of presence of material in the material space, and a higher frequency range at which such energy is transmitted to the other transducer only when material is present in the space between the transducers.  Detection circuitry indicates presence of material between the transducers upon receipt of the higher frequency energy, and failure of the apparatus upon failure to receive the lower frequency energy.

Filed: 1993-11-23
Abstract: A body compatible stent is formed of multiple filaments arranged in at least two sets of oppositely directed helical windings interwoven with one another in a braided configuration. Each of the filaments is a composite including a central core and a case surrounding the core. In the more preferred version, the core is formed of a radiopaque and relatively ductile material, e.g. tantalum or platinum. The outer case is formed of a relatively resilient material, e.g. a cobalt/chromium based alloy. Favorable mechanical characteristics of the stent are determined by the case, while the core enables in vivo imaging of the stent. The composite filaments are formed by a drawn filled tubing process in which the core is inserted into a tubular case of a diameter substantially more than the intended final filament diameter. The composite filament is cold-worked in several steps to reduce its diameter, and annealed between successive cold working steps. After the final cold working step, the composite filament is formed into the desired shape and age hardened. Alternative composite filaments employ an intermediate barrier layer between the case and core, a biocompatible cover layer surrounding the case, and a radiopaque case surrounding a structural core.
