Inventor: LAWS WILLIAM
IPC: G21C7/36
Filed: 1958-01-07
Abstract: 827,436. Electric measuring systems. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 26, 1959 [Jan. 7, 1958], No. 581/58. Class 40(1). [Also in Group XL (a)] Measuring equipment in a nuclear reactor comprises two elements each sensitive to corelated variables and means for producing an output signal proportional to the ratio of the magnitude of one variable to a function of the magnitude of the other variable. The volume of coolant flowing through the duct 11 into the reactor is measured by an anemometer 16 comprises a platinum wire on a soap-stone former. This is heated so that its resistance balances a resistance 17. In this way it is arranged to simulate the heating of a fuel element, the power derived for heating coming from an amplifier 19 the power output of which is represented across a secondary winding 21. The output from 21 is rectified at 23 and passed to an electronic switch 24. A voltage derived from a neutron flux meter 14 is applied to an electronic switch 26. These switches 24, 26 are closed periodically and the voltage reaching a comparator 28 is compared with a reference voltage K so that when these are equal a switch 30 is momentarily closed. When this switch 30 closes the voltage then reaching it from 26 is passed to an alarm 31 where it is compared with an alarm point signal and if in excess the alarm is operated. Operation of this alarm may shut down the reactor. To prevent false alarms subsidiary alarms such as no-volt alarms on the anemometer and the meter 14 and high- and low-volt alarms on the switches can be included which in turn isolate the alarm 31. Other variables which may be checked include failure of gas circulating through one or more ducts ; mean core temperature; heat transfer properties of the coolant and heat exchanger characteristics.

Abstract: 492,495. Television. RADIOAKT.- GES. D. S. LOEWE. Jan. 10, 1938, No. 723. Convention date, Jan. 9, 1937. [Class 40 (iii)] A bridge circuit contains a balancing capa. city 8, which is equal to, and neutralizes, the inherent capacity 6 of a biassed rectifier 2 which separates synchronizing signals from video signals. The rectifier is a diode or a crystal detector of very low capacity. The bridge circuit consists of the rectifier, balancing capacity, and two opposing primary coils 3a, 3b of a transformer for the synchronizing signals. Capacitive coupling between the primary and secondary coils of the transformer is avoided by spacing them and by an earthed shield, Fig. 4 (not shown). When transformers for line and for framing signals are used, only the capacity of the former is neutralized, Fig. 5 (not shown). The bias for the rectifier is derived from the anode resistance 13 of a video amplifier 7 through a filter 15, 16 which removes alternating voltages.

Patent JP-S5697588-A (JP)
Title: Contact aeration method
Inventor: NIIMI TADASHI
IPC: C02F3/10
Filed: 1980-01-01
Abstract: PURPOSE: To facilitate contact aeration, by floating a filter lighter than water on the surface of water to adhere and grow bacteria thereon, and feeding air bubbles from the downside.  
     CONSTITUTION: A bottle transporting container 5 is made of polyethylene, floatable on the surface of water, and latticed at its bottom and sides for light-weightening of the container. Such a container is useful as a filter for contact aeration. Bacteria 6 adhere onto the latticed parts, and play an important role in decontamination of filthy water. The latticed parts at the bottom and sides have a shape suitable for smooth passage of air bubbles 3, so that the air is easily fed to the bacteria adhering onto the surfaces. A polyethylene bag may be used, in which oyster shells or the like and foamed resin filters are packed at such a rate that the total weight is lighter than water. In this case, contact aeration is performed only by charging the bag in the water. Because the oyster shell is not heavier than natural stone, it is useful as a filter. Besides, the oyster shell acts as an alkali source necessary for nitrification of ammonia contained in the filthy water, and also suitable as an irregular filter effective in maintaining an anaerobic atmosphere.
