Title: Nuclear power plant with superheating reheater cooler than evaporator - gives high efficiency without adversely affecting reactor characteristics
Inventor: ORLOV VIKTOR VLADIMIROVICH
IPC: G21D5/08
Filed: 1975-01-10
Abstract: A nuclear power plant comprises a reactor, a primary circuit, opt. also a secondary heat transfer circuit, and a steam generating circuit contg. an economiser, evaporator and super-heater and also an intermediate superheater (reheater) for steam drawn from an intermediate tapping point in the turbine. The heat supply to this intermediate superheater is provided by a tapping from the secondary heat transfer circuit (in the case of a three-circuit system as shown) or from the primary circuit (in the case of a two-circuit system) at the outlet from the evaporator; the heat supply fluid is returned to the same circuit (secondary or primary) at the low temp. side. Used for three-circuit systems esp. sodium-sodium-steam or two-circuit systems esp. gas-steam or water-steam. As compared with an earlier system where the heat supply fluid in the (secondary or primary) heat supply circuit was subdivided into two parallel flows, one for the main superheater and the other for the intermediate reheater, and then recombined before passing through the evaporator and economiser, the present arrangement permits a high thermal efficiency to be obtained without the need to increase the reactor core/diameter ratio with a consequent reduction in the regeneration of secondary fuel. Also, the situation of the intermediate superheater in a zone of lower temp. means that austenitic steel is not required for its construction.

Title: Depth and location detection of buried pipes - uses magnetic field generated in region of pipe and measured at two heights above ground
Inventor: CRESCINI JEAN
IPC: G01V3/06
Filed: 1976-04-26
Abstract: The technique is intended for detecting buried pipes and measuring their depth. A magnetic field at a given frequency is set up around the pipe and the field is measured above the ground so that the points where it is maximal are determined. This gives the position of the pipe. Its depth is determined by measuring the magnetic field at two points on the same vertical and separated by a fixed distance. The deffirence (D) between the values (H1, H2) measured is used to form the quotient of the value (H1) of the field at one of the measurement points devided by the difference (D). This gives the depth of the pipe w.r.t. the position of the other measurement point.

Title: Magnetic tape disposition monitor - provides signal indicative of tape location in proximity of magnetic recording head
IPC: G01B11/14
Filed: 1977-04-08
Abstract: The presence or absence of a magnetic tape(5) in a proximity of a read or write head is determined by an electro-optic system. A light source(3) projects a beam through a focussing lens(4) into a prism(1). The prism has a superior surface against which a cylindrical lens(2) abuts. In the absence of a tape, light entering the prism(1) leaves through the cylindrical lens(2) whereas, when tape is present, total internal reflection occurs. In the latter case, light escapes from an inferior surface of the prism(1) to be detected by a control transducer(13) of the recorder. An optical beam splitter(10) permits observation by a user of tape stacks.
