Patent CA-2196841-C (CA)
Inventor: DE CAUMIA BRUNO
IPC: C10B47/40
Filed: 1997-02-05
Granted: 2001-04-03
Abstract: A horizontal moving and stirred bed reactor for heat treating particulate material comprises a housing having an inlet for admitting therein the particulate material to be heat treated and an outlet for discharging the heat treated material, at least one tray disposed horizontally inside the housing between the inlet and outlet and having a support surface for supporting a bed of the particulate material, a heating system for heating the bed of particulate material on the support surface, and a conveyor system for moving the bed of particulate material while being heated along a predetermined direction on the support surface. The conveyor system includes a plurality of horizontally spaced-apart rake members extending across the support surface transversely of the predetermined direction and each having a plurality of spaced-apart fingers in sliding contact with the support surface. The rake members are moved to displace with the fingers the particulate material along the predetermined direction, the fingers of any one of the rake members being misaligned with the fingers of any other of the rake members and being spaced relative to one another such that the fingers rake across substantially the entire support surface of the tray and constantly stir the particulate material while displacing same, thereby constantly exposing fresh surfaces of the particulate material to heat and increasing heat transfer in the bed. The horizontal moving and stirred bed reactor of the invention can be used not only for pyrolyzing particulate material, but also for drying particulate material and carrying out various reactions requiring heat.

Title: Dual bed xylene isomerization
Inventor: REISCHMAN PAUL THOMAS
IPC: B01J29/44
Filed: 1995-11-16
Granted: 2007-06-26
Abstract: A mixture of aromatic hydrocarbons, comprising ethylbenzene and at least one xylene, is isomerized using a two component catalyst system to convert the ethylbenzene to compounds that may be removed from the aromatic hydrocarbon stream and to produce a product stream wherein the para-xylene concentration is approximately equal to the equilibrium ratio of the para-isomer. The first catalyst comprises an intermediate pore size zeolite that is effective for ethylbenzene conversion. The first catalyst is preferably silica-bound. The second catalyst comprises an intermediate pore size zeolite, which further has a small crystal size and which is effective to catalyze xylene isomerization. Each of the catalysts of this invention may contain one or more hydrogenation/dehydrogenation component.

Title: Hearing aid
Inventor: ANDERSEN HENNING HAUGAARD
IPC: H04R25/00
Filed: 1995-05-29
Granted: 1999-08-03
Abstract: Described is a hearing aid with a microphone (1), a signal-transmission unit (2, 3) for forming or otherwise processing the signal, an output amplifier (4) to which an earphone (10) is connected, and a battery as the power supply. The output amplifier (4) is designed essentially as a .SIGMA.-.DELTA.amplifier and is connected to a pulse generator (8) which produces a high-frequency pulsed signal in the 1 MHz region as well as a series-connected low-pass filter (15). The input signal to the signal converter is a representation, produced by signal processing, of the low-frequency input signal to the hearing aid, this signal being converted in the signal converter into a signal which can have only two possible values. The output signal (14) thus appears, after passing through the low-pass filter, essentially as an amplified copy of the lowfrequency input signal.

Title: Compounds with chelation affinity and selectivity for first transition series elements, and their use in medical therapy and diagnosis
Inventor: KLEIN OFER
IPC: A61K31/44

Granted: 2004-12-14
Abstract: This invention involves synthesis and use of a class of compounds having fomula (I) wherein: p and q are each independently integers of from 2 to 3; r is an integer of from 0 to 4; R2, R3 and R4 are each independently selected from the group consisting of H, alkyl, alkenyl, aryl, arylalkyl, alkoxy, alkylthio, alkenoxy, alkenylthio, aryloxy, arylthio, alkyl interrupted by one or more oxa, alkenyl interrupted by one or more oxa, alkyl interrupted by thia, alkenyl interrupted by thia, aryloxyalkyl, alkoxyaryl, aminoalkyl, aminoalkenyl, aminoaryl, aminoarylalkyl, hydroxyalkyl, hydroxyalkenyl, hydroxyaryl, hydroxyarylalkyl, halogen substituted versions therof; R1 is a member selected from the group consisting of R2, R3, R4, and radicals of formula (V) and wherein, optionally, any two of R1, R2, R3 and R4 are combined to form a ring structure; said dimers therof, said dimers being formed by the covalent attachment of two complexing agents of formula (I) through a linking group having from 1 to 6 carbon atom;- and physiological salts thereof with the proviso that the molecular weight of said complexing agent does not exceed 2000, which chelation affinity and selectivity for first transition series elements. Administration of the free or conjugated compound, or physiological salts of the free or conjugated compound, results in decrease in the in vivo bioavailability of first transition series elements and/or removal from the body of first transition series elements and elements with similar chemical properties. These characteristics make such compounds useful in the management of diseases associated with a bodily excess of first transition series elements and elements with similar chemical properties. This invention demonstrates that such compounds inhibit mammalian, bacterial, and fungal cell replication and are therefore useful in the treatment of neoplasia, infection, inflammation, immune reponse, and in termination of pregnancy. Since these compounds are capable of decreasing the in vivo availability of tissue iron they are useful in management of free redical mediated tissue damage, and oxidation mediated tissue damage. When combined with radioisotopic or paramagnetic cations of first transition series elements, or elements with chemical properties similar to those of first transition series elements, prior to their administration, the resulting complexes are useful as diagnostic agents in nuclear medicine and magnetic resonance imaging (MRI).

Title: Heat treatment of carbon materials
Inventor: LYNUM STEINAR
IPC: C09C1/56
Filed: 1996-07-05
Granted: 2008-03-11
Abstract: The invention concerns a method for heat treatment of carbon materials and especially carbon black in a plasma process for increased order in the nanostructure, i.e. an increased degree of graphitization in the carbon black particles. The process consists in an upgrading of commercial carbon black qualities and non-graphitic carbon materials. The heat treatment is conducted in a plasma zone where the residence time and power supplied are controlled in order to ensure that the carbon material does not sublimate. Thus the carbon which is supplied to the plasma zone is prevented from being transformed and reformed into a new product.

Abstract: In transmission of optical signals in a dispersive medium, the signals are transmitted simultaneously in two modes in an optical fibre (15), which are orthogonal to each other, one of the signals being a non-chirped amplitude modulated signal modulated by an amplitude modulator (3), and the other signal is a phase modulated signal modulated by a phase modulator (5). The received signal is formed by the sum of the amplitude modulated contributions of the two signals. In an optical fibre system, two orthogonal modes of po~rization in the same fibre can be chosen. In this manner it will be possible to transmit high bit rates and primarily over long distances.
