Title: TDM system to measure electrical power and energy - uses two pulsed logic units t- control voltage and current signal for device integration
Inventor: SCHULZ JUERGEN
IPC: G01R21/127
Filed: 1978-10-26
Abstract: The electrical power and energy measuring system uses the time division principle. One version of the circuit comprises a triangular waveform signal generator to inject a signal to a modulator alongside an input signal X, the modulated signal passing to a control logic unit, also fed with a rectangular pulse signal from another generator. The latter operates a second logic unit. The logic units each control analogue value switches on either side of a current pulse analyser with parallel resistors and RC feedback branches. This part of the circuit acts as a frequency chopper. The first switch sends alternate positive and negative pulses to an integrating amplifier in parallel with an active filter. The second switch synchronises the voltage and current pulses, which are conveyed to a differential amplifier and a voltage/frequency converter. The final power value is expressed as a proportionate frequency.

Title: Biological fermentation of cotton in indigenous bacteria - giving detoxification with respect to dermal flora for improved wearer health
Inventor: PALM HUBERT DR MED
IPC: D06M16/00
Filed: 1979-11-08
Abstract: Chemically clean and unadulterated cotton fibre, yarn or fabric is subjected to biological fermentation by indigenous yeasts and bacteria in neutral or slightly acidic solution in pure, i.e. partic. chlorine-free, water at temps. below 37 deg.C, pref. at about 28 deg.C, for periods of 0.5-7 days, pref. 1-5 days. Auxiliary fermentation agents or assistants of animal, vegetable or mineral origin may be used, partic. lactic acid extracted from milk. The treated cotton is pref. rested for 12-24 hours before being washed and fixed, and it may be given a short -duration heat-treatment. In its natural state, cotton is inimical to epidermal flora, and therefore less healthy than, e.g. wool and linen for bedclothes, underwear, etc. This treatment effects a biological transformation of the cotton which removes its toxicity and improves the health and well-being of the wearer of garments made from it.

Title: Dynamic gas carbon-di:oxide closed circuit laser - has branch channel to heat proportion of gas before entry into jet and resonator
Inventor: MESSERSCHMITT-BOELKOW-BLOHM GM
IPC: H01S3/0953

Abstract: In the gas circuit (10) a branch (12) before the heater stage (11) channels some gas for heating so that it may be re-introduced into the circuit at the entry to the Laval jet (14). The heated gas (20) is mixed with the cold gas (19) in 1:10 proportions in the area (13) in front of the Laval jet (14) which itself has proportions of F:FL of 1.1 to 3. The gas channel (12) may be equipped with a regulating valve and a burner output in the area in front of the Laval jet (14). The regulating valve is pulsed at between 10Hz and 1kHz by a control circuit. The closed circuit has a resonator (15) followed by a diffuser (16). The gas is cooled (17) and compressed (18) before it re-enters the branch (12) preceding the heater (11). A 10:1 ratio of cold to hot gas is used and a mix temp. of 300-550K results. Inversion is achieved but further cooling due to great expansion after the Laval jet is not necessary so effecting material savings.
