Patent DE-3466745-D1 (DE)
Title: Device for the electromagnetic transmission of an event in a disturbed environment
Inventor: SUTER MAX
IPC: G04F8/08
Filed: 1984-05-09
Granted: 1987-11-12
Abstract: The electromagnetic transmission in an interference-laden environment of events defined by the time of their occurrence is accomplished by repeatedly generating, at equal intervals after occurrence of the event, signals representing the occurrence of the event. An event which must be defined by the time te at which it occurs triggers a switch which in turn triggers a time base whose signal is sent to a counter. The counter produces at its output a sequence of pulses which are coded in a coder. The code indicates for each pulse the deviation in time  DELTA Ti which separates it from the time at which the event occurred. The sequence of pulses is sent electromagnetically to a receiver via a transmitter. The first interference-free pulse received is processed by a decoder which provides the value  DELTA Ti to an arithmetic unit. The arithmetic unit subtracts the value  DELTA Ti from the time of day th to obtain the time of day te of the event. The device is applicable in particular to the timing of sporting events.

Abstract: A process for filtration of matter from a liquid suspension through a membrane uses a rotor within a concentric shell rotating with a surface velocity which, together with the rotor-shell gap and suspension viscosity, establishes vigorous vortex cells about the rotor. At least one of the rotor and shell surfaces include a filter membrane. Tangential velocity components at the membrane surface constantly sweep the membrane surface to limit cell deposition tendencies while constantly replenishing the medium to be filtered. The vortex cells are established along the length of the membrane despite the constant extraction of filtrate and the resultant change in physical characteristics of the suspension.

Abstract: A method and an apparatus for determining the dielectric constant of a material (11) wherein the material is loaded to a short-circuited microstrip (10) and microwaves are fed to the microstrip for providing a reflected signal (V<sub>4</sub>). The reflected signal is compared with a reference signal (V,) both under load and not load conditions of the microstrip for obtaining the modulus and the phase of the reflection coefficient, the dielectric constant being a function thereof. The measure of the phase angle between the reference and the reflected signal in both conditions is obtained by handling the reflected signal with a first phase shifter (6) and a second calibrated phase shifter (7) cooperating with a zero detector (4). The method and the apparatus of the invention is especially designed for a quick and easy measure of the amount of unburnt coal in the ash coming from a combustion heater.

Abstract: A self contained sensor module (1) mounted on a power transmission line (2). The module is capable of measuring various parameters such as line current, voltage, conductor temperature, and ambient temperature. The parameter values are processed by sensor electronics (25) which digitize and transmit the values to a ground receiver. The sensor module normally derives its power through electromagnetic induction resulting from current flowing through the transmission line. The module contains a power back-up system (27), including a battery, which allows sensor operation with minimum current and zero current in the transmission line. The battery is float charged while the sensor is mounted on the transmission line using excess energy derived through electromagnetic induction. When line current drops to a predetermined minimum value, float charging is disabled and the battery supplies power to the sensor module. When battery power is depleted to a predetermined level, data processing and transmission are disabled until the battery can be recharged.

Abstract: A method of depositing a substantially hydrogen free or controlled hydrogen content multi-element alloy film on a substrate. The method utilizes a microwave excited plasma of a hydrogen free precursor gas to deposit a hard, adherent coating. The method comprises providing a substrate to be coated in a vacuum deposition chamber, with a source of microwave energy coupled to the vacuum deposition chamber. A substantially hydrogen free reaction gas precursor composition is introduced into the reaction chamber at a pressure corresponding substantially to a pressure minimum of the modified Paschen curve for the reaction gas precursor composition. Activation of the source of microwave energy excites the reaction gas precursor composition, in this way forming a plasma in the vacuum deposition chamber to deposit a substantially hydrogen free or controlled hydrogen content multi-element alloy film on the substrate.

Abstract: A direct method for detecting very low levels of coliform contamination in products for human consumption comprises contacting the microorganisms with a methylumbelliferone substrate. The substrate is hydrolyzed into methylumbelliferone by an enzyme given off by the microorganisms. Hydrolysis is accelerated by sodium lauryl sulfate, which renders the microorganisms more permeable to the substrate, the enzyme, or both. The methylumbelliferone is detected by its fluorescence, either in solution or on an agar medium supporting microcolonies formed from individual microorganisms. <IMAGE>
