Title: Nuclear fuel element having oxidation resistant cladding
Inventor: ADAMSON RONALD B
IPC: G21C3/20
Filed: 1989-03-02
Granted: 1993-06-22
Abstract: NUCLEAR FUEL ELEMENT HAVING OXIDATION          RESISTANT CLADDING ABSTRACT OF THE DISCLOSURE         Nuclear fuel elements for use in the core of a nuclear reactor include an improved composite cladding having a zirconium barrier layer metallurgically bonded on the inside surface of a zirconium alloy tube, wherein the inside surface of the barrier is alloyed with preselected elemental impurities to improve oxidation resistance.  The zirconium barrier layer forms a shield between the zirconium alloy tube and a core of nuclear fuel material enclosed in the composite cladding.  The alloy layer formed on the barrier surface acts to inhibit cracking during the tube production fabrication step and limits oxidation in the event that the cladding is breached during operation of the reactor, allowing the entrance of water or steam into the fuel element.

Abstract: ABSTRACT OF THE DISCLOSURE    A sound field reproduction apparatus comprises a reflectional sound signal generating circuits for generating quasi-reflectional sound signals by summing a plurality of delay signals obtained by delaying source signals in order, and amplifiers for amplifying the level of quasi-reflectional sound signals. The apparatus is characterized by a signal selecting and repeating device for alternatively repeating either the quasi-reflectional sound signals and the source signals, or source signals different from the above-described source signals. With this feature, it becomes possible to reproduce source signals other than the source signals for use in the sound field reproduction.

Abstract: By means of the group control the average time losses for the passengers resulting from the waiting time at the floors and the return travel time are minimized. Therefore, the number of entering stops causing a minimum of time losses is determined per elevator car on the basis of calculations. The number of entering stops is stored in monitoring or control counters by means of which the allocation of down hall calls is limited to the number stored for each car. The down hall calls are combined by means of a switching circuit to form groups of chronologically inputted or incoming hall calls of a volume corresponding to the number of hall calls respectively stored in the monitoring or control counter. In the case of an increase in the hall calls, the earliest group of hall calls is first increased and the latest group of hall calls last. The increase of numbers in the group occurs by transfer of a hall call from the next later group of hall calls and the latest hall call is allocated to the latest group of hall calls. Thus, groups of hall calls are formed, each of which have the same size until the control counting state or level of the monitoring or control counter is reached. The groups of hall calls are allocated to the different cars such that the average time losses of the passengers become a minimum.

Abstract: The invention in question is a repairing machine, which is suited to repairing damaged conduits which are inaccessible for repair work. This repairing machine is remote-controlled and monitored with television cameras. At the head of the driving carriage, various devices, which are necessary for the repairs, can be attached to a motor-driven rotatable toolhead. A simple construction of the movable head has made it possible to accomplish all of the necessary movements with uncomplicated mechanics, and at the same time, to forego a tedious slide coupling for the control lines without letting them get tangled with the device. Therefore, with this invention, the production costs for the whole device could be lowered and, likewise, the proneness to repairs could be reduced.

Abstract: For controlling the level of electrical signals a circuit arrangement is formed with two series connected amplifiers. A first amplifier containing a first variable resistor, operates at maximum amplification when a low input signal level is received. A second amplifier comprises a series connection of a second variable resistor and a current-controlled voltage source with two complementary outputs. The outputs of the voltage source are connected to a comparator and a controller with two separate outputs. One of the controller outputs transmits a control signal while the other output simultaneously transmits a blocking signal. A first output of the controller is connected with the first variable resistor, while a second output of the controller is connected to the second variable resistor.
