Patent CA-2037785-A1 (CA)
Title: Fire extinguishing apparatus for burning gas-and oil-wells
Inventor: KALETSCH REINHOLD
IPC: E21B33/12
Filed: 1991-03-07
Abstract: ABSTRACT          In fighting gas- and oil- well fires so far only large quantities of water have been used to cool the very hot steel debris which would reignite the burnable materials, then using dynamite to blow out the flames  In this invention the burning zone is usually first moved away from the well head by lack of oxygen to avoid the other-wise constant reheating of the steel  debris around the well head, and the burnable materials and the well head area are over time cooled below the reigniting temperature in and by that oxygen-free environment. The final extinguishing  of the flames happens by shutting off the first provided exits for the burnable gases and deducting them simultaneously to a different outlet away from the first provided exits.
Patent CA-2039977-A1 (CA)
Inventor: NISSEN PETER
IPC: G01F1/00
Filed: 1991-04-08
Abstract: A liquid flow measuring system which, by means of a suitable timing sequence, is able to detect unbalanced voltage generation which occurs when the tube element through which the liquid is flowing is not completely full and, by means of a correction process, supplies an output signal which is proportional to the rate of flow. When the tube element is full, the system operates in the same way as a normal magnetically inductive flowmeter. If the level in the tube element falls, electrodes which are installed in the lower half of the tube element and other electrodes, if necessary, can be used exclusively or additionally to record the measured values. Moreover, with a view to improving the recording of measured values when the level falls below a specific limit, an arrangement of electromagnets, specially optimized for partially filled tube elements, can be activated instead of the normal arrangement of electromagnets.

Title: Peritoneal dialysis apparatus
Inventor: DADSON JOSEPH E
IPC: A61M1/16
Filed: 1991-05-13
Abstract: An apparatus for carrying out peritoneal dialysis includes a central manifold, a receptacle for waste dialysate, means for supporting and heating a plurality of fresh dialysate bags, a first conduit connecting the manifold with the patient catheter, a second conduit for connecting the manifold with the receptacle, and a plurality of additional conduits connecting the manifold individually with a plurality of fresh dialysate bags. The individual conduits can be selectively closed by clamping means controlled by an electronic control, and the latter has an automatic mode which cycles the apparatus through (a) a fill/dwell phase in which the contents of one of the fresh dialysate bags flows into the patient's peritoneum cavity by gravity and remains there, and (b) a drain phase which allows waste dialysate in the patient's  peritoneum cavity to drain by gravity into the receptacle.  The steps (a) and (b) are repeated for all of the bags until they have been used up.  A safety provision is provided to determine whether a sufficient quantity of dialysate has drained from the patient's cavity during the drain phase.  If not, the apparatus is shut down.

Title: Systeme de communication radio
Inventor: HEIDEMANN ROLF
IPC: H04W92/00
Filed: 1991-06-14
Abstract: Dans un système de radiocommunication mobile cellulaire comportant des stations radio et des installations d'émission éloignées de celles-ci, les stations radio émettent et reçoivent des signaux radio qui, dans chaque cas, contiennent des signaux d'information. Dans la présente invention, le plus grand nombre possible des fonctions de traitement est transféré des stations radio aux installations d'émission. Le signal radio qu'une station radio doit émettre est facilement produit par la station radio parce que, dans l'installation d'émission, une porteuse non modulée et une porteuse modulée par le signal d'information sont produites, ces porteuses ayant des fréquences dont la différence correspond à la fréquence de porteuse du signal radio. Ces deux porteuses lumineuses sont transmises à la station radio et y sont mélangées dans un récepteur optique et le signal radio contenant le signal d'information est produit. Les signaux radio reçus par une station radio sont transmis optiquement à une installation d'émission où ils subissent un traitement additionnel. Cette émission est effectuée par un émetteur optique se trouvant dans l'installation d'émission qui produit une porteuse lumineuse non modulée et la transmet à un modulateur optique installé à la station radio. Dans ce modulateur, la lumière modulée par les signaux radio reçus est retransmise et les signaux radio sont recouvrés par hétérodynage à la réception des porteuses non modulée et modulée.
Patent CA-2048761-A1 (CA)
Inventor: ERICKSON BERT K
IPC: H03B19/00
Filed: 1991-08-08
Abstract: A frequency division network is disclosed in which a sinusoidal signal is converted to a digital format for frequency division and then converted back to the sinusoidal format, the sinusoidal output wavefrom having low phase noise. In a preferred embodiment the frequency conversion takes place in an m-fold plurality of edge triggered flip-flops, connected to divide by two, and clocked by the sinusoidal waveform. Each flip-flop is subject to fitter causing phase noise, which is minimized when the output of two sets of four flip-flops are averaged, and then filtered to obtain the sinusoidal fundamental. When a crystal filter having a very narrow pass band is employed, the phase noise is further reduced. The frequency division network uses low cost components and the phase noise of the output waveform approaches that of a stable crystal oscillator.

IPC: G01R23/165
Filed: 1992-01-23
Abstract: RD-19,737 A MULTI-RATE SUPERRESOLUTION TIME SERIES          SPECTRUM ANALYZER                Abstract Parallel architectures preprocesses large matrices from sampled coherent time apertures receiving signals from distant sources to produce lower order matrices, derived from pseudo coherent time apertures, which are computationally less burdensome.  The large matrices are processed by frequency shifting, low pass filtering with an FIR filter, and executing front-end decimation to create the pseudo coherent time apertures, each corresponding to different subbands of the temporal frequency spectrum.  The signals representing the pseudo coherent time apertures are processed using matrix based superresolution spectral estimation algorithms such as the Tufts-Kumaresan (T-K) reduced rank modified covariance algorithm and the Linear Minimum Free Energy algorithms to produce an image of the sources.
