Title: Unitized absorbent structure
Inventor: CHAUVETTE GAETAN
IPC: A61F13/53
Filed: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSURE           A unitized, composite, fluid absorbent structure for use in thin, disposable absorbent products such as sanitary napkins, diapers, incontinence pads, adult briefs, wound dressings and the like.  The unitized composite, fluid absorbent structure comprises a transfer layer of hydrophilic fibers adhered to a reservoir layer of compressed peat moss material having a higher density than the transfer layer.  A diffuse interface is defined between the transfer and the reservoir layers forming a shared, three-dimensional boundary zone containing peat moss material interspersed with hydrophilic fibers.  The invention also extends to a method for manufacturing the unitized, composite, fluid absorbent structure and to a method for improving the fluid absorption characteristics of a peat moss sheet.

Title: Semiconductive copolymers for use in luminescent devices
Inventor: HOLMES ANDREW
IPC: H01L33/08
Filed: 1991-08-22
Abstract: A semiconductive conjugated copolymer comprises at least two chemically different monomer units which, when existing in their individual homopolymer forms, have different semiconductor bandgaps. The proportion of said at least two chemically different monomer units in the copolymer is selected to control the semiconductor bandgap of the copolymer so as to control the optical properties of the copolymer. The copolymer is formed in a manner enabling it to be laid down as a film without substantially affecting the luminescent characteristics of the copolymer and is stable at operational temperature. The semiconductor bandgap may be spatially modulated so as to increase the quantum efficiency of the copolymer when excited to luminescence, to select the wavelength of radiation emitted during luminescence or to select the refractive index of the copolymer.

Title: Immunological test for the presence of antibodies in biological fluids, and a kit for carrying out the test
Inventor: BERGMANN ANDREAS
IPC: G01N33/573
Filed: 1992-06-15
Abstract: Antibodies (Ak), in particular autoantibodies, such as autoantibodies against thyroid peroxidase (TPO), are determined by a procedure in which the sample to be investigated is reacted with two further, in particular monoclonal antibodies and an antigen. The two further antibodies are an immobilised antibody (Ak imm) and a freely labelled antibody (Ak*) against the antigen (Ag), and the latter is preferably used in the form of a crude, natural antigen, for example in the form of an organ extract. The presence of the antibodies (Ak) to be determined is evident as a disturbance of the formation of a sandwich of the two added antibodies (Ak imm and Ak*) with the added antigen (Ag) and as a consequent reduction in the binding of the label to the solid phase.

Abstract: Un contrôleur de périphériques entraîné par interruptions (103) destiné à être utilisé dans un ordinateur compatible avec une architecture de norme industrielle (ISA) fournit un système qui diminue la consommation d'électricité par rapport aux contrôleurs de péripheriques conventionnels. Ledit contrôleur de péripheriques (103) utilise un contrôleur à interruptions internes (110) qui répond à des signaux d'entrée venant d'un microprocesseur serveur compatible ISA, d'un clavier (112), d'une souris et d'autres unités reliées aux accès d'entrée et de sorties de l'ordinateur compatible ISA. Le contrôleur à interruptions (110) fournit un registre d'interruptions pour le contrôleur de péripheriques (103) et produit une interruption chaque fois qu'une ou plusieurs des unités commandées par le contrôleur de péripheriques (103) sont activées. Ledit contrôleur de péripheriques (103) entre en mode de faible consommation d'électricité si aucune interruption n'est détectée pendant un laps de temps prédéterminé. Lorsque le contrôleur à interruptions (110) génère une interruption, le contrôleur de périphériques est activé, et quitte le mode de faible consommation et dessert la ou les unité(s) qui ont provoqué l'interruption.
Patent CA-2097703-A1 (CA)
Title: Method and an apparatus for filling a closed spacer frame with a drying agent
Inventor: MADSEN JOERGEN S
IPC: E06B3/66
Filed: 1991-11-28
Abstract: A method of filling a spacer frame is described. A corner of the frame is positioned in relation to a positioning pin (21), whereas a surface (79) of two of the sides of the frame is positioned in relation to driving pins (40) which have a contact surface extending in a plane which is tangent to the circumference of the positioning pin (21). The driving pins form a part of or are combined with separated working units (6) which comprise a pierce needle (32) for forming an opening (82), a filling nozzle and a hammer for re-closing the opening (82). The opening (82) is formed in a lateral surface (85) of the profile of the frame and in the vicinity of an adjacent surface (79). When the frame is positioned correctly in relation to the pins (21 and 40) all three working tools can thereby be activated while the frame is maintained in a groove (41) in each working unit. Thus, there is no risk that the frame is incorrectly positioned between the different working sequences. Nor is there any risk that the supplied drying agent leaks as the frame is re-closed in an effective way by an outwards deformed part (80) of the adjacent lateral surface (79). By means of the hammer (68) this part is directed inwards to a position (81) where the opening (82) is re-closed.

Title: Snowplow
Inventor: GINSBERG ERIC
IPC: E01H5/02
Filed: 1993-07-07
Abstract: ABSTRACT           A snowplow comprises a moldboard made of a one-piece molded material  and an elongated handle extending upwards  from a handle attachment  system provided  at  the  rear  of  the  moldboard.     The moldboard also includes a blade defining a concave front  surface  having  the  cross-section  of  a composite curve.  The blade comprises opposite first and second ends,  the first end being smaller than the  second  end  with  a scraping  edge  extending therebetween at a lower front end of the blade.  The scraping edge extends in an oblique direction with respect to a direction of travel of the snowplow with the second end being located rearward of the first  end  when  the  handle  is  oriented  in  the direction of travel of the snowplow.  The axis of the handle and this direction of  travel lie in a same vertical plane.   The  composite  curve cross-section is characterized by portions of gradually reducing radii  from the  scraping  edge  towards  an upper  edge  of  the blade.    The  blade  defines  an inturned  upper  end  of  inverted  U-shaped cross-section and of increasing depth from the first end toward  the  second  end.    The  inturned  upper  end terminates in the forwardly and downwardly extending upper edge of the blade.   In  operation,  snow  is lifted by the scraping edge and picked up by the blade.   The  snow carried by  the blade  gradually displaces therealong towards the second end thereof whereat  it  is  discharged from  the  snowplow.    A series  of  parallel  grooves  defined  in  the  front surface of the blade are angled to assist in the advancement of the snow towards the discharge end of the snowplow.

Patent CA-2103714-A1 (CA)
Title: Transmission of well-logging data over bandpass channels using quadrature amplitude modulation
Inventor: MONTGOMERY MICHAEL A
IPC: H04L27/20
Filed: 1992-02-05
Abstract: A method and apparatus for transmitting and receiving acquired digital data over bandpass channels (i.e. channels having a limited range of frequencies) at high data transmission rates. Combined amplitude and phase modulation (quadrature ampli-tude modulation) is applied to the digital data and the sampled digital waveform converted to an analog waveform for passage over the bandpass channel. The sample rate is chosen as an integer multiple of the symbol rate and carrier frequency to signifi-cantly reduce processing overhead. Reception of the acquired data is similar to transmission and involves an analogous ampli-tude and phase demodulation. The quadrature amplitude modulation technique of the present invention is applied to an oil well-logging application to transmit the data acquired from the downhole logging instruments over the logging cable (bandpass channel) at high transmission rates.
