Abstract: An arrangement for supporting the head portions of the coils which project beyond the ends of the slots provided in the laminated stator component of a high-output turbo-generator in which the coils are placed includes inner and outer radially spaced rings made from a glass fiber-reinforced thermosetting synthetic resin and between which the cylindric array of the insulated coil heads is secured, and a supporting ring secured to the general housing structure of the generator which surrounds and is spaced radially from the outer coil head securing ring. A ring structure of a rubber-like resilient material, e.g. india rubber is interposed between and contacts corresponding faces of the supporting ring and the outer coil head securing ring for the purpose of compensating for unequal expansion coefficients of the copper conductors of the stator coils and the iron of the laminated stator component. This resilient ring structure which may be in the form of a continuous ring, or sub-divided circumferentially into a cylindric array of uniformly spaced arcuate sections between which non-resilient arcuate sections can be placed, has a trapezoidal profile in cross-section, the two non-parallel faces of the ring being constituted by a radially inner face parallel to the axis of the generator and a radially outer face inclined to the generator axis. The radially inner face is provided with axially spaced, circumferentially extending slots which increase the resiliency of the material in the axial direction.

Abstract: The position determining device (10) exhibits a mask (16) which can be displaced along an axis (T) located in the reference plane. A light source (20) can be displaced together with the mask (16). A sequence of photocells (26) with a lens (26a) contains photocells (PC1-PC7). The mask (16) contains transparent sections and opaque sections. Planes (P1, P2, P3), in which the radiation-reflecting objects (O1, O2, O3) are located extend in parallel with the said axis (T). The time required by the radiation pattern to pass over a location in the planes (P1, P2, P3) is a measure of the distances (x1, x2, x3). When light source (20) and mask (16) are displaced, the objects (O1 - O3) are successively irradiated by light, with intermediate periods without radiation. During the displacement of the pattern, the sequence of photocells (26) detects an energy reflection by the objects (O1 - O3). An output signal is generated at the rate of the pulse repetition rate and is processed in order to establish the object distance. <IMAGE>

Abstract: A glass material is directed into an elongate enclosed conversion chamber, where it is either converted to or maintained in a molten state by heating through the Joule effect. Waste material is directed onto the glass material at the inlet end of the conversion chamber, and sufficient oxygen is directed into the chamber to cause combustion of the waste material which is capable of being burned. A portion of the ashes created by combustion fall on the glass material and become a part thereof. The gaseous combustion products proceed horizontally through the elongate conversion chamber, and additional ash material suspended in the gaseous combustion products settles onto the glass material and also becomes a part thereof. The gaseous exhaust is directed through a plurality of ceramic fiber filter components which capture the small particulate material that remains suspended in the gaseous exhaust. These filter components are periodically discharged into the molten glass material to become a part thereof and/or to become oxidized. The glass material, with the other material added thereto, is periodically discharged to a cooling area to form a solidified product incorporating the ash product of the waste material.

Abstract: Method and container for transporting, storing and recovering material, such as fibre flock, which to a certain extent recirculates back to the store. The object of the present invention is to bring about this transport, storage and recovery of fibre flock without using special cyclone separators. Handling is also simplified, so that a flock cloud is not formed when the flock material is transferred from the transport container to the feed-out arrangement of the installation. This has been achieved by virtue of using as the transport and storage container a container 11 made of a flexible material, for example a plastic sack with a volume greater than the volume of the material, the filling opening 19 of the container being connectable to a feed-out arrangement 30 in such a way that the container 11 is inverted, and an outlet 13 being connected centrally to the inverted container bottom 12 and a tangential inlet 16 for airborne surplus material being connected to the container wall 15 close to the outlet 13. <IMAGE>

Abstract: A self-test system for a nuclear power plant, nuclear reactor protection system is disclosed. Nuclear protection systems are the electronic controls, typically including circuit cards, located intermediate between sensors (as for detecting core overheat) and a control (as for providing rod injection to shut down a reactor). Constant surveillance of the nuclear system protection system is provided by a microprocessor that serially addresses protection system circuit cards and loads them at pre-determined input points with test commands. The addressed cards are thereafter simultaneously activated by a system-wide command. The test command is a pulse which is so short in duration that its affect is transparent to the system and cannot cause overall system operation. The pulse passes through the actuating electrical components to verify, on the real actuating path, the operating integrity of the system. After an appropriate response interval, the output state of the system is recorded in system-wide resident registers. Thereafter, with response data contained in these registers frozen at the recorded state, the output is read. This result is compared with the expected output in computer memory. If correspondence between memory output and register output is found, the next sequential set of test commands is acted upon. If correspondence is not found, a subroutine search is automatically conducted to locate the error. The disclosed self-test subsystem is duplicated in four separate divisions with each division testing one of the four duplicate protection systems. The three remaining and idle divisions constantly monitor the active subsystem's operation. The end result is an overall system which reduces the mean time to discover error, thus minimizing mean time to repair and maximizing protection system availability and safety. The separation of the protection system into four duplicate divisions is not dependent on the disclosed invention and the invention may be applied to protection systems with a different number of divisions.
