Title: Sulfur dioxide detector device embodied by using so2-oxidant bioagent
Inventor: SATO TAKESHI
IPC: G01N33/00
Filed: 1991-10-01
Abstract: ABSTRACT        In a sulfur dioxide detector embodied by using SO2-oxidant microbe, a bio-membrane is located at one end of an oxygen concentration sensor, the bio-membrane consisting of the SO2-oxidant microbe provided between an immobilized membrane and a gas permeable membrane. The sensor has an electrode in contact with the immobilized membrane of the bio-membrane. A dish-shaped cell has an open end which is in contact with the gas permeable membrane so that SO2-involved solution supplied to the cell causes to oxidize sulfurous acid to sulfuric acid during which the SO2 permeates through the bio-membrane so as to change an output from the sensor. An inlet and outlet hole are formed on a sidewall of the cell. The outlet hole is located to be always right above the inlet hole so as to drain foam occasioned at the time when the SO2-involved solution is supplied to the dish-shaped cell through the inlet hole and drained from the outlet hole.

Title: Total field imaging probe
Inventor: CLOT ANDRE
IPC: E21B47/01
Filed: 1990-07-27
Abstract: The invention relates to the principle of a probe to improve the quality of imaging logs in excavations providing especially a good coverage of the wall (2) of the excavation by the beam of detectors (4) or electrodes. The basic component consists of a casing (6) moulded from an elastomeric material and made to allow it to be unfolded in the working position for helical measuring regions (7) and applied against the wall (2). The material of the measurement regions (7) is selected depending upon the parameter to be measured and the immediate but non-restrictive applications concern microresistive and acoustic imaging. The helical arrangement of the detectors (4) improves the coverage of the measurements over that of conventional probes. Moreover, by eliminating the drilling mud (3) between the detectors (4) and the formation, this probe improves their response and the quality of the measurements in certain cases, like acoustic imaging, for example.
Patent CA-2060964-A1 (CA)
Title: Brake for transmission
Inventor: HAVENS DALE I
IPC: F16D55/00
Filed: 1992-02-10
Abstract: ABSTRACT The present invention is a brake arrangement for a transmission.  On one of the shafts of the transmission drive train, a brake disc is rotatably fixed and axially movable so that adjacent friction pucks may be pressed into the disc and retard the speed of the drive train.  The transmission housing includes openings which allow access to the friction pucks, so that dismantling the housing is not required to replace the friction pucks.  Specifically, by removing the pressing pins, the disc may move axially allowing access to one friction puck through one of the openings, and after removal the disc may again move axially allowing access to a second friction puck through the other opening.  For replacement, simply reverse the removal steps using new friction pucks.  To help stiffen the backing plate of the puck which are pressed by the pins, the backing plate is provided with an upper flange which also distributes the pressing force of the pins more uniformly over the surface of the friction puck.

Title: Earthing Switch for a Metal-Encapsulated High-Voltage Switchboard Plant Insulated by Pressurised Gas
Inventor: LORENZ DIETER
IPC: H01H31/00
Filed: 1990-08-14
Abstract: In a grounding switch for an encased high-voltage switching system, the movable switching piece is moved by a rotating drive shaft, which passes through the housing of the grounding switch.  In order to design the contact elements, which transfer the ground potential to the movable switching piece, in as simple a manner as possible, the drive shaft consists of electrically conductive material and is introduced into the housing in an insulated manner.  The drive shaft is connected with means to transfer the ground potential, e.g. a current strip, outside the housing.  The drive shaft therefore serves both to transfer force and to transfer potential.  A switch blade is designed to be elastically deformable in part and serves as the movable switching piece.  Such a grounding switch for an encased, compressed-gas-insulated high-voltage switching system can thus be used also as an insulated grounding switch, to carry out measurements.

Filed: 1992-03-13
Abstract: The process of the present invention first synchronizes to incoming messages from the base station. The first data word is received and stored in the radiotelephone. The error code in the data word is next checked to determine if errors ex-ist in the word. If there are errors, the word is corrected. This process is repeated on another data word and the second received word is compared with the first. If the words are not equal, the receiver remains on until at least two words are equal or the entire length of the message is received. If the words are equal, the word is processed by the radiotelephone and the receiver is turned off for the remaining portion of the message until the next synchronization word is to be received.
