Title: Temp. measurement of high voltage cryoelectronic components - using opto-electrical transducers for transferring signals between temp. regions
Inventor: NOACK FRIEDHELM DR ING
IPC: G01K1/02
Filed: 1979-12-22
Abstract: A device measuring temp. in cryoelectro-technical equipment is applicable to measurements on components at high voltages. The signal transfer between the normal temp. region at earth potential and the low temp. region at high voltages take place in both directions without expensive insulation. Temp. measurement is performed using energy conversion. The measurement value is transferred through the thermal and electromagnetic fields via a medium acting simultaneously as an electrical and thermal insulator. Light energy from a radiation source at earth potential in the normal temp. region is directed to an optical-to-electrical energy transducer at high voltage and converted to electrical energy. This transducer drives the temp. sensing electrical-to-optical energy converter whose output intensity varies with temp.

Title: Shock wave detection device for IC engines - utilises vibrator with piezoceramic ring and compares spectra or characteristic frequency for correct and incorrect operation
Inventor: HAMISCH HANS-JOACHIM DR ING
IPC: G01L23/22
Filed: 1980-02-06
Abstract: The sensor is for detection of shock waves associated with knock in internal combustion engines and ensures reliable knock detection by using a frequency lying in a region of max. signal-to-noise ratio. This frequency lies well above the audio frequency noise region. The characteristic frequency is determined by comparing the spectrum for normal operation and the spectrum modified by the knock shock wave. Conventional knock vibration sensors may be used. These may be flexural oscillators for low frequencies and expansion oscillators for frequencies above 50 Hz. A piezoceramic ring expansion vibrator may be used. This may be a single or two-part device. The two part ring would have parts of opposite polarisation fixed to the vibration transfer component of the engine.

Patent DE-3139781-A1 (DE)
Title: Process and equipment for purifying a gas containing pollutants in vapour form
Inventor: FORS BENGT GOESTA
IPC: B01D53/04
Filed: 1981-10-07
Abstract: The subject is a process and equipment for purifying a gas, in particular air, containing pollutants in the vapour form. For this purpose, the gas to be purified is passed through a purification vessel (1) in which a cooler (5) and an adsorption filter (2) are arranged behind or above the latter. The gas inlet (13) is located in front of or below the cooler (5). The gas outlet (14) is located behind or above the adsorption filter (2). A condensate outlet (18) is provided in the bottom of the vessel (1). For the purpose of cleaning the filter, the gas feed is stopped and the pollutants precipitated in the filter (2) are reconverted into their vapour form and subjected again to cooling. The resulting condensate is discharged together with or separately from the pollutants previously precipitated in the gas purification. To extend the life of the filter (2), the conversion of the pollutants, precipitated in the filter (2) into their vapour form is carried out under a reduced pressure (vacuum). The reduced pressure is generated by connecting a vacuum source (vacuum pump 7) to the vessel (1). Preferably, the vacuum source (vacuum pump 7) is connected to the gas inlet (13), so that the pollutant vapour is passed again through the cooler (5) located in the vessel (1). As a result of the reduced pressure, the boiling points of the pollutant precipitated in the adsorption filter (2) are considerably lowered, so that no temperature increases, which adversely affect the life of the filter (2), are necessary for vaporising the pollutants. <IMAGE>
