Title: Dynamic control of transmitting power at a transmitter and attenuation at a receiver
Inventor: BORG LARS UNO
IPC: H04B7/26
Filed: 1994-05-10
Abstract: A communications system includes a receiver and a transmitter for transmitting a communications signal to the receiver. The transmitter adjusts its transmission power level in response to receiver power control signals transmitted by the receiver. The receiver includes an attenuator for attenuating the received communications signal, and measurement means for measuring the signal strength of the attenuated signal. The measured signal strength is coupled to attenuator control means and to transmission power control means. The attenuator control means and the transmission control means adjust, respectively, receiver attenuation and transmitter power level so as to optimize system performance. This may include keeping the attenuated signal within the dynamic range of the receiver. This may also include eliminating disturbance signals by adjusting receiver attenuation to produce an effective dynamic range for receiving only signals having a signal strength level that is higher than the disturbance signal strength level, while at the same time increasing the transmission power level to keep it within the effective dynamic range of the receiver. The disturbance signal may be detected as an increased bit error rate of the received communication signal. The apparatus and method may also be applied to systems in which a plurality of receivers are coupled to a common antenna through a receiver multicoupler.

Title: Self-confirming assay devices
Inventor: DONOVAN JAMES J
IPC: G01N33/543
Filed: 1993-09-08
Abstract: The novel analytical devices and methods of the present invention involve dual pathway devices which provide for the con-firmation of sandwich or competitive assay results. In a self-confirming sandwich assay, the labeled analyte complex becomes im-mobilized within a first pathway at an assay capture site to indicate the presence or amount of an analyte in the test sample. In a second pathway, a confirmatory reagent blocks the binding of the analyte or labeled analyte complex to a confirming assay site, thereby confirming that the presence of label in the assay capture site indicates a positive test sample. In a self-confirming com-petitive assay, a confirmed positive result is one in which the device displays a decrease in signal or no signal at the assay capture site, and the confirming assay site displays a detectable signal.

Title: Process for the thermal production of energy from waste material, particularly refuse
Inventor: FORSBERG STEFAN
IPC: C10B7/04
Filed: 1995-05-11
Abstract: Waste material is conveyed in an uncomminuted state on a grate (5) through a combustion chamber (12) of a stationary furnace (10) and at the same time mixed by a thrust and shearing action of the grate (5).  A gaseous oxidizing agent is introduced, for example via gas lances, into the combustion chamber (12) from above the layer of waste material (11) lying on the grate (5).  The oxidizing agent cooperates with the combustible volatile substances escaping from the waste to form flames.  The layer of waste is heated by the thermal radiation of the flames such that degasification occurs.  The combustible gases thus freed are partially burnt.  The waste material freed from the volatile substances, that is to say refuse coke, and the unburnt volatile substances, that is to say combustible gases, can be used as fuels outside the plant or within the plant.  The oxidizing agent does not come into contact with the thermally stressed parts of the plant.  It is thus possible to use oxidizing agents having a high oxygen content of up to 100%.  This results in an enormous reduction of flue gases by up to 80%.

Title: Parietaria allergens
Inventor: MOHAPATRA SHYAM S
IPC: C07K14/415
Filed: 1995-07-21
Abstract: Screening of a Parietaria pollen-.lambda.gt22 library with antisera to a 14-kDa pollen protein from Parietaria led to the identification of several cDNA clones encoding allergenic proteins.  Nucleotide sequence analysis of these clones indicated that, on the basis of the sequence homologies, these clones may be classified to three groups; group I (PJ001) comprising seven isoallergens, group II (PJ002) comprising two isoallergens and group III (PJ003) with three isoallergenic variants.  Four of these cDNAs were expressed in pCNAII vectors which bound to the murine antibodies.  IgE binding assay with 15-residue peptides designed from the deduced sequences of one of the group I proteins revealed a dominant IgE-binding region which spanned two overlapping peptides, peptides #27 and #28. These peptides are conserved among all of the group I iso-allergens.  Furthermore, a murine monoclonal antibody directed to a major Parietaria-allergen bound to peptide #28, suggesting that this peptide is recognized by mouse antibodies as well.  In a splenocyte culture of mice immunized with Parietaria allergens, peptide #28 stimulated the production cytokines IL-2, IL-4 and IFN-.gamma., whereas, peptide #23 stimulated production of only cytokine IFN-.gamma.. Furthermore, Parietaria-specific antibodies were found in sera of North American subjects and these antibodies were shown to bind the 14 kDa Par j I allergen. Accordingly, these recombinant Parietaria allergens are useful in both diagnosis and therapy of allergic diseases induced by Parietaria pollens.

Patent CA-2158141-A1 (CA)
Inventor: SOLTYS PAUL
IPC: B01D69/02
Filed: 1995-02-03
Abstract: Un procédé présenté par les membranes (88) à deux peaux s'avère utile pour les membranes anti-retour ou de rectification car il réduit la filtration en retour des molécules de soluté en dialyse et améliore l'apport en nutriment et la collecte des matières rejetées par les bioréacteurs à membranes. Les membranes sont des matériaux polymères à deux peaux se présentant de préférence sous forme de fibres creuses. Les peaux (12, 14) en polymère de chaque face des membranes sont caractérisées par une différence entre leurs coefficients respectifs de filtration et de perméabilité aux solutés. La peau de chaque face est munie de pores invisibles à un agrandissement de 10.000 fois. Une structure microporeuse (16) entre les peaux contient des pores pouvant retenir en concentration plus élevée, entre les peaux intérieure (14) et extérieure (12), des solutés dont le poids moléculaire se situe entre environ 5000 et 200.000. Les dispositifs à dialyse sont réalisés en faisceaux de membranes en fibres creuses servant d'éléments de dialyse dotés de propriétés de rectification. En répétant les cycles de passage de la solution dans l'un et l'autre sens au travers de la membrane (88), il est possible de séparer et concentrer le soluté sur l'une des faces de la membrane (88).

Title: Method and plant for regenerating sulfate electrolyte in steel strip galvanizing processes
Inventor: KUHLMANN JOACHIM
IPC: C25D21/18
Filed: 1996-01-31
Abstract: A method and a plant for regenerating sulfate electrolyte in steel strip galvanizing processes by precipitating dissolved iron from the iron cycle, wherein a partial quantity to be regenerated is removed from the cycle of the electrolyte and the iron dissolved in the partial quantity is oxidized to Fe3+ by a redox-controlled addition of oxidizing agents.   Subsequently, by raising the pH value to the precipitation limit by a controlled addition of a ZnO/water suspension or a ZnCO3/water suspension,  the dissolved iron is precipitated as sludge.  Any excess ZnO or ZnCO3 is then dissolved by adding fresh electrolyte.  The   precipitated   iron sludge is conducted through a suitable filter, such as, a filter press, a filter belt, a decanter, etc., and the precipitated iron is filtered out in this manner.  Subsequently, the purified partial quantity of the electrolyte is returned into the cycle.
