Title: Method of making injection-molder heating element
Inventor: SCHWARZKOPF EUGEN
IPC: B29C45/72
Filed: 2000-03-17
Abstract: A method of making a heater element has the steps of inserting into a smooth tubular casing a heating wire, filling a space between the wire and the casing with a compressible insulating mass, and closing ends of the space to confine the mass in the casing. Then the casing is radially inwardly compressed to form therein a successive of radially outwardly open annular grooves extending circumferentially fully around the casing and thereby radially compressing the insulating mass. The casing is formed with a succession of such grooves, which can be of V-shape and which are each endless so that the casing is corrugated.  Alternately the grooves are interconnected helically. Either way in accordance with the invention the grooves form axially relatively long and radially relatively thick outer rings and axially relatively short and radially relatively thin inner rings.

Title: Heater door safety interlock for infant warming apparatus
Inventor: JONES THOMAS C
IPC: A61N5/06
Filed: 2000-03-13
Abstract: An infant warming apparatus that functions both as an infant incubator as well as an infant warmer. The apparatus has a heater that moves vertically with respect to an infant support during the change in function between an infant incubator and infant warmer. A powered motive system, such as an electric motor, powers the movement of the heater between its upper and its lower positions. The heater also has a door or doors that are open when the heater is in it upper position so that the heater can direct energy toward the infant to warm the infant when acting as an infant warmer. When closed, the doors isolate the heater to prevent the inadvertent touching of the heater by the infant or attending personnel. A safety interlock system is provided that prevents the heater from being activated unless it is in its upper position and the door or doors are fully open. In addition, the interlock system also monitors the downward movement of the heater and discontinues that downward movement if the heater reaches a predetermined position and the door or doors are still in the open position. As a further interlock safety feature, a sensor also senses when the heater has reached its lower position and stops further downward movement of the heater.

Title: Data transmission system with relay stations between a source station and a target station
Inventor: MECKELBURG HANS-JURGEN
IPC: H04B7/155
Filed: 1998-08-27
Abstract: A decentralized digital data transmission system has a large number of distributed stations which can only engage in direct data communication with neighbouring stations.       Stations located between a source station and a target station function as relay stations. Station to station transmission occurs in each case on different channels. In each station signals received by a reception channel are converted onto a different transmission channel. Conversion of a bit flow or symbol flow arriving at said reception channel is carried out on a bit-by-bit or symbol-by-symbol basis so that data is transmitted in a continuous flow without long delays occurring during conversion as is the case for transmission of data packets. A coupling matrix (KM) is used for conversion. Each channel (C1...Cn) is divided into a plurality of sub-channels (CH-1...CH-8). Transmission channels are allocated in such a way that each station uses wherever possible only sub-channels (SC1...SC8) located in the same channel.

Title: Chimaeric adenoviruses
Inventor: VOGELS RONALD
IPC: C12N15/861
Filed: 1999-07-08
Abstract: The present invention provides methods and vector systems for the generation of chimaeric recombinant adenoviruses. These hybrid adenoviruses contain a genome that is derived from different adenovirus serotypes. In particular, novel hybrid adenoviruses are disclosed with improved properties for gene therapy purposes. These properties include:  a decreased sensitivity towards neutralizing antibodies, a modified host range, a change in the titer to which adenovirus can be grown, the ability to escape trapping in the liver upon in vivo systemic delivery, and absence or decreased infection of antigen presenting cells (APC) of the immune system, such as macrophages or dendritic cells. These chimaeric adenoviruses thus represent improved tools for gene therapy and vaccination since they overcome the limitations observed with the currently used serotype subgroup C adenoviruses.

Patent CA-2322174-A1 (CA)
Title: Cardiac rhythm management device using transthoracic impedance
Inventor: STESSMAN NICHOLAS J
IPC: A61N1/365
Filed: 1999-02-26
Abstract: A cardiac rhythm management (CRM) device detects transthoracic impedance, extracts ventilation or other information, and adjusts a delivery rate of the CRM therapy accordingly. A four-phase sequence of alternating direction current pulse stimuli is periodically delivered to a patient's thorax. A transthoracic impedance signal is extracted using a weighted demodulation. Signal processing extracts ventilation information and removes cardiac stroke information using an adaptive lowpass filter. The adaptive filter cutoff frequency is based on the patient's heart rate; a higher cutoff frequency is provided for higher heart rates. Peak/valley detection indicates tidal volume, which is integrated to extract minute ventilation (MV). Short and long term averages are formed and compared to establish a MV indicated rate. Rate adjustment ignores MV information when a noise-measurement exceeds a threshold. An interference avoidance circuit delays delivery of the stimuli when telemetry pulses or other interfering signals are detected.

Title: Free jet centrifuge
Inventor: FISCHER HELMUT
IPC: B04B7/00
Filed: 1999-04-16
Abstract: The invention relates to a free jet centrifuge, especially for cleaning the lubricating oil of an internal combustion engine. The aim of the invention is to provide a centrifuge which is economical to produce and at the same time allows for high speeds. To this end the invention on one side of the rotor provides for a ball bearing (16) in the housing, which engages a closed shaft journal (14) of the rotor.  In the area of this bearing the rotor is sealed so that the friction in the ball bearing is not raised by the oil pressure in the centrifuge. A slide bearing is provided for on the other side of the rotor which consists of a bearing bushing (20) and a sliding bush (21). In this way a combination of materials which is optimal in terms of tribological properties can be selected. A hollow journal (19) which also acts as oil inlet (24) for the centrifuge rotor is inserted into the sliding bush. To increase speed even further the invention provides for a pulse channel (30) which discharges into nozzles (31). This device is integrated into a plastic base of the rotor (13) which permits the production of highly precise input nozzles (31).

Inventor: MARTIN GREGORY R
IPC: A61N1/37
Filed: 1999-05-06
Abstract: L'invention concerne un stimulateur cardiaque capable de mesurer l'impédance de la stimulation cardiaque. Le stimulateur comprend un condensateur bouchon, qui permet de délivrer une charge au coeur via les dérivations du dispositif ; un shunt ; et des tampons haute impédance, qui mesurent le courant de stimulation traversant le shunt. Peu après le bord avant de l'impulsion de stimulation, la tension dans le shunt, échantillonnée par un tampon haute impédance, indique la résistance de la dérivation et du tissu cardiaque. Juste avant l'ouverture du commutateur de stimulation mettant fin à l'impulsion de stimulation, la tension dans le shunt est échantillonnée par un tampon et bloquée une nouvelle fois pour permettre de calculer la capacité de la dérivation/du tissu cardiaque. Dans d'autres modes de réalisation, un tampon haute impédance mesure la tension entre le condensateur bouchon et la terre immédiatement après l'impulsion de stimulation, de façon à permettre l'estimation de la capacité de la dérivation/du tissu cardiaque. Dans un autre mode de réalisation, un table de recherche est créée dans la mémoire principale et consultée de façon à obtenir la meilleure estimation de la capacité de la dérivation/du tissu cardiaque avec un degré de précision arbitraire. Dans encore un autre mode de réalisation, la capacité de la dérivation/du tissu cardiaque est estimée par approximation successive jusqu'à un degré de précision arbitraire. Une fois que la capacité de la dérivation/du tissu cardiaque et la résistance de la dérivation ont été déterminées, on peut calculer une pluralité de paramètres importants pour analyser et optimiser un système de stimulation cardiaque, tels que courant instantané, courant moyen, charge et énergie délivrée au tissu cardiaque.
Patent CA-2332374-A1 (CA)
Inventor: OZBEK ALI
IPC: G01V1/36
Filed: 1999-05-18
Abstract: A method relating to filtering coherent noise and interference from seismic data by constrained adaptive beamforming is described using a constraint design methodology which allows the imposition of an arbitrary predesigned quiescent response on the beamformer. The method also makes sure that the beamformer response in selected regions of the frequency-wavenumber space is entirely controlled by this quiescent response, hence ensuring signal preservation and robustness to perturbations. Built-in regularization brings an additional degree of robustness. Seismic signals with arbitrary spectral content in the frequency-wavenumber domain are preserved, while coherent noise and interference that is temporally and spatially nonstationary is adaptively filtered. The approach is applicable to attenuation of all types of coherent noise in seismic data including swell-noise, bulge-wave noise, ground-roll, air wave, seismic vessel and rig interference, etc.  It is applicable to both linear or areal arrays.
