Title: Low-noise digital communication system - converts amplitudes into digital signals using clock pulse counter and comparator
IPC: H03M1/00
Filed: 1973-06-20
Abstract: The low-noise digital telecommunications system converts amplitude of the analog information signals into a digital code for transmission. At the transmitter, clock pulses are counted and the sum converted into an analog signal whose amplitude is then compared with the information signal's amplitude sample. When the converted signal's amplitude is signal to the information signal's, the coupling process is stopped and the contents transmitted as the digital code. At the receiver, the n-bits of transmitted information are converted into p-bits (p>n): The sequence of levels chosen for the p-bits is such that the distance between two consecutive level is least. The p-bits are then converted into an analog output signal.

Title: Gasifying liq partic for biological purificn of sewage - by oxygenation in which escaping gas is reinjected
IPC: C02F3/26
Filed: 1973-06-25
Abstract: Process of mixing an additive gas into a liq. in which additive gas is injected via downward-directed nozzles just below the surface of liq. in a covered tank and gas passing through the liq. to collect in the head space above the liq. surface is reinjected into the liq. e.g. by drawing gas from the head space into a compressor which delivers to injection nozzles near the bottom of the tank; alternatively reinjection of gas can be effected by a turbine impeller drawing gas back in from the head space. For gasifying liqs., partic. injecting oxygen gas or oxygen-enriched air into waste water undergoing biological purification. The initial injection can be at a comparatively low pressure which obviates compressing the additive gas to any great extent. Reinjection of gas escaping at the surface ensures that optimum use is made of the additive gas.
