Patent CA-2214512-A1 (CA)
Inventor: YAMAMOTO KAORU
IPC: C08G2/06
Filed: 1997-04-10
Abstract: To economically produce a polyacetal copolymer excellent in properties including thermal stability by copolymerizing trioxane as the main monomer through simple steps, a polyacetal copolymer is produced by copolymerizing trioxane as the main monomer using a nonvolatile protonic acid catalyst as a polymerization catalyst until the conversion reaches at least 60% (based on all monomers), and then vaporizing unreacted monomers to separate, remove, and recover the same from the polymerization system to thereby reduce the residual monomer content of the polymerization system to 5% by weight or lower.

Inventor: LILLIE WILLIAM ROSS
IPC: A47C7/00
Filed: 1997-09-26
Abstract: A rolling base for supporting objects rolling across a floor or other surface has castors mounted on radial arms that are in turn pivotally mounted on the base for vertical movement of the castors. Bridge elements link adjacent ones of the arms and are themselves pivotally mounted on the support base to act as walking beams. This allows each castor to rise and fall as it traverses an uneven surface or obstacles on the floor. Four or more castors may be used.

Title: Rapid assays for the assessment of organ status based on the detection of one or more isoenzymes of glutathione s-transferase
Inventor: DOYLE JOHN MARTIN
IPC: G01N33/543
Filed: 1996-04-02
Abstract: A method for the rapid assessment of organ status, including organ damage following immunological or toxicological insult, in a subject based on the detection of one or more isoenzymes of glutathione S-transferase (GST) in diverse biological fluids comprises contacting a particle-labelled anti-GST antibody specific for said isoenzyme with a sample of a biological fluid suspected of containing said isoenzyme, said antibody having a sensitivity sufficient to detect at least at picomolar amount of said isoenzyme, and capturing the particle-labelled antibody-isoenzyme complex on an immobilised capture antibody to generate a visually detectable signal. The method permits the detection or determination of GST isoenzymes typically in a time of the order of 30 minutes from initial contact with immobilised anti-GST antiboby. The method is simple to use and thus can be used, for example, by patients at home to monitor their levels of a particular GST isoenzyme following a liver or renal transplant.

Patent CA-2230932-A1 (CA)
Inventor: ICHIHARA MASAKI
IPC: H04L1/06
Filed: 1998-03-03
Abstract: Radio-frequency signals received by two antennas are respectively amplified by two amplifiers. Of the two signals, only the radio-frequency signal received by the second antenna is delayed by a delay time T through a delay circuit. The output from the delay circuit and the output from the first amplifier connected to the first antenna are combined by a combiner. From this stage toward subsequent stages, a shared receiver lowers the frequency of the combined signal to that of a base band signal, which is converted into a digital signal by a shared A/D converter. This digital signal is demodulated by a Rake receiver, and the demodulated result is decoded by the decoder to reproduce transmitted data.

Title: Adjustable shoulder rest for violins or the like
Inventor: VAN DEN AKKER WILHELMUS
IPC: G10D3/18
Filed: 1998-03-11
Abstract: The adjustment of the distance between clamping elements (13, 14) of a shoulder rest for violin or the like instrument is effected by a stem-like fastener, preferably a thumbscrew (37) passing through one of generally equidistantly spaced apart openings (29, 30) in a foot member (17) and through that opening (29, 30) which is aligned with one of at least two nuts (33, 34) embedded in an elongated base of the shoulder rest. According to the invention, the longitudinal spacing between the openings (29, 30) differs from that of the nuts (33, 34) preferably such that one spacing is one-half of the other, whereby a fine adjustment of the clamping distance can be achieved, while the number of the nuts (33, 34) and/or the openings (29, 30) is relatively small, in the embodiment shown, two of each, permitting a total of four different adjustments of the clamping distance.

Abstract: L'invention porte sur un étalon atomique de fréquence miniaturisé (1) dans lequel on utilise une cellule de vaporisation tubulaire (7, 75) traversant une cavité (15, 77) à micro-ondes TE¿210?. Dans l'une des variantes de l'invention, la cellule de vaporisation (7) est réchauffée directement par des chauffages électriques (57) placés à ses extrémités et se prolongeant à l'extérieur de la cavité (15), et elle comporte une isolation thermique (59, 61) dans la cavité à micro-ondes et entre cette cavité (77) et un blindage magnétique (19). Dans une autre variante, la totalité de la cavité à micro-ondes (77) est chauffée, ce qui élimine la nécessité d'une isolation interne de la cavité et permet de réduire son volume, mais une isolation thermique (87) supplémentaire est prévue entre la cavité à micro-ondes (77) et le blindage magnétique (85). On prévoit de préférence un enroulement à champ en C (89) bobiné sur l'isolation thermique (87) à l'intérieur du blindage magnétique (85) pour réduire les pertes thermiques par conduction. Une diode à laser (27) extérieure au blindage magnétique (19, 85) éclaire la cellule de vaporisation (7, 75) par l'intermédiaire d'une fibre optique (35) sans nécessiter de lentille collimatrice, tandis qu'une photodiode (51) à lentille intégrée (53) sert de détecteur (47).

Abstract: Mail pieces are produced by an apparatus which includes a printer, for printing a plurality of documents and envelopes in response to signals generated by a host computer under control of an application program. A mail finishing unit forms a plurality of mail pieces from the documents and the envelopes. A control unit controls the mail finishing unit to form an individual one of the plurality of mail pieces with individual attributes, or characteristics, such as envelope configuration, numbers of inserts, folds of the insert, and other characteristics. The attributes of any one mail piece may be different from attributes of others of the mail pieces, so that each mail piece may have individual attributes. The control unit receives the signals generated by the host computer; and is programmed to parse the signals from the host computer and to extract therefrom control signals generated under control of the application program. The control signals identify the individual attributes for the individual one of the plurality of mail pieces. The control unit responds to the extracted control signals by generating finishing control signals for the mail finishing unit to form the individual one of the plurality of mail pieces with the individual attributes. The control unit is further programmed to extract print signals for the print unit from the signals and to provide print control signals to the print unit responsively thereto. The application program may be a word processor, which outputs document pages for printing by the printer. A user may provide a particular format or protocol to a document page, preferably to the first page output by the word processor, which designates that page to the control unit as a control page including the various control signals. Upon recognizing the control page, the control unit extracts the same from the word processor output, so that the printer does not print, or attempt to print, the elements thereof as text.
