Title: Optical monitor for oil-filled transformer - detects low oil level, air and gas bubbles using optical fibres with gap
Inventor: RUCHHOLTZ CARSTEN DR ING
IPC: G01F23/292
Filed: 1979-08-23
Abstract: The device monitors the level of oil in the casing of a transformer. It isesp. adapted for detecting excessively low oil level, and thus guard against explosions. The device uses two optical fibres or light conductors (1,2) with a gap (5) which is normally filled with oil. There is a lamp (4) underneath the casing and the light passes up the first light conductor (1) to the gap (5). Light crossing the gap (5) passes down the second light conductor (2) to a photocell (6). There is a funnel (7) in an inverted position under the gap (5). Air, gas and oil all have different refractive indices, and give a different signal at the photocell (6), with the result that low oil level and the build up of air and gas bubbles can be detected.

Title: Refuse compositing system - by thermal rotting in layers intermittently laid on air filter bed
Inventor: WILLISCH HANNES
IPC: C05F7/00
Filed: 1980-01-17
Abstract: The Parent Patent No. 2909515 described a thermal rotting process for converting refuse or a refuse-sewage sludge mixture into compost. The material is stored under aerobic conditions in a layer of up to 1.2-1.5 m, for at least 3 weeks until the layer has become matted before the next layer is applied. This is again allowed to become matted and this is repeated for all subsequent layers, pref. in gradually diminishing thickness. Perforated tubes with a mesh size of 7-10 mm give access to the air. After 3 weeks, a new layer of the same height is added and the tubes are raised accordingly. This ensures an undisturbed activity of the aerobic bacteria without producing any nests of putrefaction until the entire store has been sanitised. This system operated satisfactorily under extreme conditions of heavy rainfall and strong solar radiation.

Patent DE-3004146-A1 (DE)
Title: Measuring illumination intensity by using photodiode - avoiding load dependency and nonlinearity by compensation of dark current during amplification
Inventor: ROUBAL MIROSLAV
IPC: G01J1/44
Filed: 1980-02-05
Abstract: Aphotodiode is used and avoids the expensive amplification circuitry conventionally required for low photo voltage measurements. The difficulties associated with the load dependency of the photovoltage and the nonlinear relationship between photovoltage and illumination intensity are overcome. The photodiode is raised to a voltage within the characteristic field of the photodiode in a region of photocurrent practically independent of voltage. The rate of change of voltage as the photodiode discharges is measured essentially without consuming power. The voltage on the photodiode is amplified with a gain determined by the dark current. This achieves a compensation of the dark current content of the discharge current. Voltage rate of change is measured from the time taken to reach a given voltage.

Title: Measuring circuit for percentage difference of two parameters - has two operational amplifier integrators linked by third amplifier
Inventor: HESS BRUNO M
IPC: G01R19/10
Filed: 1980-02-18
Abstract: The electrical circuit showing the percentage difference of two parameters is esp. applicable to showing the difference between the revolution rates of two motors as a percentage of the revolution rate of one of the motors. This is achieved more economically than with conventional devices. Two operational amplifier integrators (OP1,OP2) are connected together via a third operational amplifier (OP3) driving transistors (Tr1,Tr2) in their feedback loops and producing a small hysteresis. The potential difference between the outputs of the integrating amplifiers corresp. to the difference between positive voltages (U1,U2) applied to the inverting inputs of the integrating amplifiers. The potential is referenced to that input to the first amplifier (OP1), whose output remains at a constant negative value over the entire range of operation.
