Title: Digitally controlled pulse width modulator for dc motor control - provides output signal with variable duty cycle to be applied to DC motor to control rate of rotation
Inventor: SEILER HEINZ
IPC: H02P7/29
Filed: 1991-12-13
Abstract: The pulse width modulator (1) provides an output signal with a variable mark-space ratio or duty cycle, ie a pulse width modulated (PWM) signal. Several digital input values, defining the value range, are input to the pulse width modulator. These values are applied to a pre-adjustable delay counter (4) directly via a data bus (7) and by parallel connection of an inverting intermediate memory (3). The counter output is connected to a D-type flip-flop (5) which outputs the PWM signal. The intermediate memory, the delay counter and the flip-flop are joined via a control bus (6) for clock signal supply and control. USE/ADVANTAGE - E.g. for fuel powered heater for vehicle, or charger for catalytic converter, operating independently of engine. Highly accurate, simplified control by microcomputer, using suitable fundamental frequency.

Title: Gas sensor arrangement - esp. for temp. independent determination of oxygen partial pressure
Inventor: GERBLINGER JOSEF DIPL PHYS
IPC: C04B41/50
Filed: 1992-03-30
Abstract: An arrangement for determining the partial pressure of a designated gas in a gas mixt. has a first gas sensor of material with a conductivity or ohmic resistance which varies with the gas partial pressure to be determined. A second gas sensor has a stabilising system ensuring that it is surrounded by a gas constantly at the same partial pressure as the designated gas, but is otherwise exposed to the same ambient conditions as the first gas sensor. The measurement signal of the second gas sensor is subtracted from that of the first gas sensor to give an evaluation signal which is proportional to the gas partial pressure to be determined and which is independent of the gas mixt. temp. Also claimed is a method of using the above sensor arrangement for respiration monitoring, in which periodic oxygen partial pressure changes of exhaled air are determined and irregularities of the period are evaluated. USE/ADVANTAGE - The arrangement is useful for detecting oxygen partial pressures in gas mixts. from combustion processes (esp. automobile exhaust gases) or for respiration monitoring. It allows direct, temp.-independent partial pressure determinationch

Inventor: FERTL KLAUS
IPC: B24C9/00
Filed: 1992-10-23
Abstract: In a procedure for cleaning used sandblasting material, the material first undergoes a coarse cleaning process and is if necessary dried. It then enters a cleaning device in which reusable material, foreign particles and dusts are separated and placed in separate containers. The reusable material container is topped up with fresh material as required. Also claimed is an appts. for carrying out the procedure, consisting of series of devices as follows: (a) an inlet hopper, (b) a conveyor, a bucket elevator and a chute, (c) a dryer, and (d) a second elevator (5) and a cleaning unit (10) with cleaning elements (11 to 34) and a system for handling the material which is to be reused. A flow of air is imposed during all operations in which dust is produced. The dusts are subjected to suction effects of differing strengths, and dust which is collected is passed into a cyclone and/or a wet scrubber. A magnetic separation process is also applied to the blasting material. Fresh material is added to the cleaned material in accordance with its grain size, preferably before its enters the receiving container. The lower ends of the elevators (5) and the associated conveyors (4) are located in pits (9), and the upper ends of the elevators extend above the working surface (8) in such a way that the cleaning unit (10) and its associated equipment can all be located on the working surface (8).

Filed: 1992-11-23
Abstract: Process for controlling the microbial purificn. of contaminated material comprises airing the material with an oxygen-contg. gas at the start of the purificn. process at least, then controlling contaminant degradation throughout the entire process, and then when a stagnation in degradation occurs prior to a pre-determined result, the material is analysed to see whether nitrite, nitrate or anaerobic centres are present. If nitrite and nitrate are present at a concn. greater than a pre-determined value, then the material is aired, while if anaerobic centres are present then an electron acceptor other than oxygen is added to the material. USE/ADVANTAGE - Useful for pit sanitation (esp. for regeneration pits) of contaminated materials, e.g. soil from industrial or waste disposal sites. Contaminant degradation is prevented from stagnation, allowing degradation of hydrocarbons, and high nitrate levels are prevented.
