Title: Process for producing a current limiter having a high-temperature superconductor, and current limiter
Inventor: HOIDIS MARKUS
IPC: C01G1/00
Filed: 1997-08-15
Abstract: On transition from the superconducting state to the normal conducting state, current limiters having a high-temperature superconductor (3) increase their electrical resistance and thereby limit an electric current which is flowing through them. To provide electrical stabilization, the high-temperature superconductor (3) is combined with a silver foil (1) having a layer thickness of < 50 µm to form an extensive composite conductor with good conductivity. The ratio of the layer thickness of the high-temperature superconductor (3) to that of the silver foil (1) should be < 1/10. To produce this composite conductor (1, 3), the silver sheet (1) is placed on one side on a 2 mm thick MgO powder layer and, on the other side, is covered with a 600 µm thick so-called green sheet which contains a high-temperature superconductor powder and an organic binder. In order to stabilize the high-temperature superconductor mechanically after it has been fused together, a 200 µm thick layer consisting of glass or carbon fibers and epoxy resin is applied by vacuum impregnation to at least one side of the composite conductor (1, 3). In order to produce resistive current limiters, current limiter elements in sheet form, having the specified layer structure, are cut to form meanders and are bonded or pressed onto one another in at least two layers, if appropriate with the interposition of cooling elements. Inductive current limiters are obtained by bending flexible sheets of this type to form tubes and soldering a metal strip (5) of silver over a gap (9) in the ring.

Title: An acoustical audio system for producing three dimensional sound image
Inventor: GOLDFARB BARRY S
IPC: H04R5/02
Filed: 1996-04-19
Abstract: A three-dimensional acoustical audio system utilizes both spatial and temporal signal processing to maximize the depth, width, and perceived directionality of the acoustic field with respect to the binaural auditory system.  Transducers are critically placed within the confines of a reverberant enclosure (10), and each transducer (2, 6 or 8) is assigned a specific bandwidth of sound either in mono (8) or stereo (2 or 6), depending upon the spatial location of the transducer to take advantage of the binaural auditory system of the intended listener (4). The system minimizes the number of transducers and electronics required to achieve the effect of a live performance, regardless of the dynamics of the enclosure in which it is placed. The loudspeaker system can be used in small enclosed volumes such as an automobile or extended to volumes the size of a motion picture theater or concert hall and even outdoors.

Patent CA-2224117-A1 (CA)
Inventor: MCEWAN THOMAS E
IPC: G08B13/181
Filed: 1996-05-22
Abstract: A range gated strip proximity sensor uses one set of sensor electronics and a distributed antenna or strip (57) which extends along the perimeter to be sensed. A micro-power RF transmitter (10) is coupled to the first end of the strip and transmits a sequence of RF pulses on the strip to produce a sensor field along the strip. A receiver (12) is coupled to the second end of the strip, and generates a field reference signal in response to the sequence of pulses on the line combined with received electromagnetic energy from reflections in the field. The sensor signals comprise pulses of radio frequency signals having a duration of less than 10 nanoseconds, and a pulse repetition rate on the order of 1 to 10 MegaHertz or less. The duration of the radio frequency pulses is adjusted to control the range of the sensor. An RF  detector feeds a filter capacitor (65) in response to received pulses on the strip line to produce a field reference signal representing the average amplitude of the received pulses. When a received pulse is mixed with a received echo, the mixing causes a fluctuation in the amplitude of the field reference signal, providing a range-limited Doppler type signature of a field disturbance.
Patent CA-2227276-A1 (CA)
Inventor: SKAUG KJELL
IPC: C12Q1/6862
Filed: 1996-06-26
Abstract: La présente invention se rapporte à un contrôle interne utilisé dans une "réaction en chaîne de la ligase remplissant les intervalles" (Gap-LCR). L'oligonucléotide synthétique fonctionnant comme un contrôle interne possède approximativement la même longueur et les mêmes quatre sites identiques de sonde LCR que l'acide nucléique cible. Par conséquent, le contrôle interne et l'ADN cible sont amplifiés dans une Gap-LCR avec sensiblement la même efficacité. En outre, l'oligonucléotide synthétique est modifié en séquence d'intervalles entre les sondes LCR hybridisées de telle sorte qu'il contient un site pour un enzyme de restriction. En traitant le produit LCR avec cet enzyme de restriction, ce dernier va détacher le produit LCR du contrôle interne, ce qui permettra au produit LCR provenant de la cible d'être analysé séparément. Le contrôle interne de l'invention peut donc être utilisé à la fois pour des analyses à base de LCR qualitatives et quantitatives.

Abstract: La présente invention concerne de nouveaux récepteurs protéiques anti-opioïdes (OFQR) mammifères, de nouveaux ligands peptidiques (tel que des OFQ) se liant aux OFQR, ainsi que des procédés d'utilisation du peptide OFQ et de ses analogues afin d'inverser les effets physiologiques d'opiacés tels que la morphine. Cette invention concerne également l'isolement, la caractérisation et l'utilisation pharmacologique du ligand peptidique endogène. Dans un mode de réalisation particulier, le peptide OFQ est un heptadécapeptide ayant un motif d'aminoterminal FGGF. Ce peptide se lie spécifiquement à un récepteur protéique OFQ exprimé de manière hétérologue dans des cellules de mammifères. Ce peptide ne se lie par avec une grande affinité aux récepteurs µ, .delta. ou ?, mais permet de contrer des effets induits par des opioïdes (tel que l'analgésie et l'hypothermie) sans pour autant accroître la sensibilité nociceptive. Des variantes à substitution tyrosine du ligand peptidique se lient spécifiquement au récepteur opioïde et peuvent être radio-iodées. Cette invention concerne également des procédés de production de ces ligands peptidiques et de ces antagonistes d'OFQR, ainsi que des procédés d'utilisation de ces ligands à des fins diagnostiques et thérapeutiques et dans l'identification d'autres ligands de récepteurs opioïdes d'origine naturelle ou synthétique.

Abstract: In a transmission system wherein redundant message cells, routed in the course of virtual connections according to the ATM (Asynchronous Transfer Mode) transmission method, are respectively transmitted via redundant transmission paths, a rejection of message cells belonging to a low-priority connection is permitted on the transmission paths to form the total traffic volume. To avoid an overload following the recombination of the message cell streams transmitted via the redundant transmission paths, the message cells of a connection of low priority are received by only one transmission path. For a number of connections, a selection identification character defines the transmission path by which the message cells belonging to these connections are received.

Title: Apparatus for buffering the dc voltage at the output of a power supply
Inventor: GEHRE HANS-JOACHIM
IPC: H02J7/34
Filed: 1996-10-23
Abstract: The buffer apparatus contains at least one buffer battery (BATT), in particular a rechargeable battery which can be charged via the power supply (SV), and a control unit (CU). The latter connects the buffer battery when the actual value of the DC voltage (Ua) is less than a predetermined minimum value (Uamin), generates a predetermined buffer time period (tm) and disconnects the buffer battery again, cyclically, after this time period has elapsed. The apparatus according to the invention has the advantage that the return of the output DC voltage of the power supply can be identified effectively without major complexity. The loads continue to be supplied both in the event of a failure of the supplying input voltage and in the event of a failure of the rower supply, since the output DC voltage, which is essential for the loads, of the power supply is monitored. The apparatus can be connected additively downstream of a power supply, without any intervention in its design being necessary.      The apparatus has the further advantage that it automatically connects the battery as a back-up, even in the event of drops in the output DC voltage caused by short-circuits, as soon as the load voltage falls below the minimum value. The invention thus enables a virtually continuous transfer and back-up of the output DC voltage in a multiplicity of fault situations.
