Inventor: JACQUET PHILIPPE
IPC: H04L12/56
Filed: 1993-03-30
Abstract: 2133432 9320636 PCTABS00164 Chaque poste de traitement de données est muni d'une interface-réseau (RE), coopérant avec un dispositif de gestion d'émission/-réception (ARC) donnant des ordres confirmatifs d'émission ou de réception. Chaque poste comporte un dispositif d'émission-réception radio pluri-directionnelle, avec un émetteur-récepteur (RD) de canal central, pour l'échange des messages, un émetteur-récepteur auxiliaire (R1) opérant sur au moins un canal latéral, et qui change d'état en réponse à une collision détectée, et un émetteur-récepteur sur un second canal latéral (R2), pour émettre un signal d'occupation tant qu'un signal démodulable est reçu sur le canal central. L'émission de données est interdite pour tout poste dont le dispositif d'émission-réception radio reçoit le signal d'occupation sur son second canal latéral. En l'absence de trafic naturel suffisant, le dispositif de gestion est apte (ARC; ADF) à forcer l'émission de messages artificiels, afin de maintenir un calage mutuel des fréquences pilotes des différents postes.

Title: Enzymes produced by mutants of geotrichum candidia
Inventor: OESTER DEAN A
IPC: C12N1/14
Filed: 1993-07-21
Abstract: A mutant fungal strain, namely G. candidum NRRL Y-552, mutant known as Henkel 9-2-3-9 produces a lipase called "UNLipase" providing a selectivity of 25:1 for oleic acid over palmitic acid by the assay procedure employed. UNLipase has a temperature range of operation of between 0 and 40 degrees Celsius (and no activity over 55 degrees Celsius). The optimum pH ranges are between 7.5 and 8.5. Magnesium cations increase activity, whereas calcium cations are inhibitory. The molecular weight of the protein appears to be 65 kDa by size exclusion chromatography. UNLipase shows a high degree of selectivity for hydrolysis, esterification and transesterification.

Title: An Improved Method for Reverberation Suppression
Inventor: DRAGOSET WILLIAM H JR
IPC: G01S7/527
Filed: 1994-07-13
Abstract: A method for reducing the effects of reverberation noisy seismic wavefields recorded from within a moisture-laden environment. The wavefield manifests itself as a pressure signature and a velocity signature that contains an embedded noise signature. The pressure signature is adaptively filtered and subtractively combined with the velocity signature to isolate a nearly pure noise signature. The nearly pure noise signature is added back to the original velocity signature with opposite sign to clear away the embedded noise, leaving a refined velocity signature. The refined velocity signature iteratively is scaled and summed with the pressure signature, incrementing the scale factor at each iteration and autocorrelating the sum. A coefficient of convergence is calculated after each summation. The coefficient of convergence that most closely approaches unity identifies the preferred scale factor.

Title: Method and apparatus for dispensing foam materials
Inventor: BOCCAGNO GEORGE E
IPC: B29C44/34
Filed: 1995-05-03
Abstract: A method and apparatus for dispensing a polymer foam includes apparatus  for forming a pressurized solution of intermixed polymeric material and gas.

Title: High activity polyethylene catalysts
Inventor: HAGERTY ROBERT OLDS
IPC: C08F10/02

Title: Adjustable arm-rest
Inventor: KARLSSON GOERAN
IPC: A47K17/02
Filed: 1995-04-24
Abstract: With the intention of providing an arm-rest which can be readily adjusted vertically and laterally and intended, for instance, for a toilet or lavatory seat, and which has but few movable parts, there is provided a positionally adjustable arm-rest which includes an arm-rest part and a frame-part, wherein one end (1) of the arm-support part is inserted together with two surrounding slide blocks (5) into the frame-part (3) such as to enable said arm-support part to be retained in its raised or lowered position. With the arm-rest in an essentially non-loaded state, the slide blocks (5) fix the arm-rest in a horizontal position and hold the arm-rest in this position. The end of the arm-rest also includes a pressure surface (6) which acts against the inner surface of the frame-part so that the arm-rest will not give way when subjected to load. The user can readily adjust the position of the arm-rest. All that is required in this regard is for the user to grip the arm-rest part and swing it slightly upwards while moving the same to the position desired. When the end of the arm-rest has been moved to the height desired, the arm-rest part is released and swung back. The arm-rest part is now fixed in position and can be subjected to load, by virtue of the pressure surface on said end of the arm-rest. Lateral adjustment of the arm-rest is achieved by virtue of the frame-part (3) resting on a rotatably adjustable floor plate (16), or being rotatably mounted to a wall structure.
