摘要： It is proposed to store spent nuclear fuel elements in welded-shut steel containers, which are filled with argon at about 2 atmospheres pressure. It is desirable to be able periodically to check the containers for leaks. The invention proposes to do this by providing apparatus for sensing the pressure within the container from outside the container. To achieve this, a pressure responsive bellows is mounted inside the container, such that changes in the container pressure move a metal plate attached to the bellows towards or away from a portion of the inside wall of the container. Then, if the container starts to develop a leak, the pressure will begin to drop, and the gap between the metal plate and the wall will change. This gap can be sensed from outside the container, by an ultrasonic pulse echo technique. Preferably, the bellows and plate are mounted within the head of the combined valve and lifting pintle by which the container is sealed.

摘要： A receiver, for receiving a signal comprising a carrier signal modulated with a digital signal, comprises a circuit for demodulating the received signal to produce an output signal which contains the digital signal. Because of repeated filtering, the digital signal is typically in the form of an approximately sinusoidal signal, which has a component whose frequency is equal to half the basic bit rate of the digital signal: because of noise, this component is subject to considerable timing jitter. To overcome this, the output signal is digitized and applied to a digital correlator, where it is correlated with a reference signal whose frequency is also equal to half the basic bit rate of the digital signal. The reference signal is preferably derived from a phase-locked loop locked to the carrier frequency. The correlator, which is constituted by a microprocessor, determines the instants of time which most nearly coincide with the mean-level crossing points of said component (which instants correspond to transitions between one bit of the digital signal and the next), and also determines successive bit values on the basis of the coincidence determination. The receiver can be used to receive mains-borne signals, i.e. signals transmitted over an electrical power supply network, or radio broadcast signals.

摘要： A cable connector hood includes a housing formed of two mating portions and including at least one gripper element pivotably receivable within that housing and pivotally mounted for movement into gripping engagement with a cable connected to a cable connector received within the hood. Detent structure provides for resilient engagement between the gripper and the housing to maintain the gripper in engagement with the cable.
