Abstract: An apparatus for shaping profiles in the surface of a moulded semiplastic body (4) comprises a comparatively fine wire (1) extending between the free ends of a plurality of these supporting members such as needle-like supporting members (2,3) which determine the profile shape. The wire is zigzagged in such way that each individual wire portion extending between two adjacent supporting members is oblique in relation to the direction of relative movement between said body and the profile shaping apparatus itself. The apparatus produces extremely distinct profiles with good smoothness of the body surfaces. The apparatus is primarily used for shaping profiles in building units made from a body of lightweight or aerated concrete, while the body is still uncured and semiplastic.

Abstract: Error detection and correction method and apparatus for use with digital data signals, which have been coded using cross-interleaving error correction codes with added check words prior to transmission, employ a plurality (k) of syndrome word signals SO. . . Sk-1) that are generated by multiplying one block (Vt) of the received digital data signals with a parity check matrix, in which each element of one predetermined row is a function of a root of an irreducible polynomial on Galois field GF (2), the syndromes are used to obtain a set of constant word signals (A, B, and C). Error detection and correction is based on these developed syndrome word and constant word signals, in which if selected syndrome word and constant word signal levels are equal to zero, there is no error word declared; if selected ones of the syndrome word and constant word signal levels are equal to zero and selected other signal levels are not equal to zero, then one error word is declared and error correction is performed by calculation of the syndrome word signals which have been determined to be the equivalent of error pattern signals; and if selected constant word signal levels are not equal to zero, additional constant word signals (D, E) are generated and an error location equation is solved to detect the error locations (i, j) and the two word errors are corrected based on the syndrome/error pattern relationship. Up to two word errors in one error correcting block can be detected and corrected and three word errors or four word errors can be corrected if the error locations are known.

Abstract: Control rods are inserted into the core of a nuclear reactor in operation to shut down the reactor output. Before completion of entire control rod insertion, a high-temperature coolant flowing in piping for a reactor water clean-up system is sprayed into the space in the upper portion of the reactor vessel. As the space is under negative pressure, oxygen existing in the water droplets of the sprayed coolant is separated. After completion of entire control rod insertion, a residual heat removal system is operated. The spraying operation is discontinued and a low-temperature coolant cooled by a heat exchanger in the residual heat removal system is sprayed into said space. The coolant sprayed by said first spraying operation is not cooled by the heat exchanger in said residual heat removal system.

Abstract: The disclosure relates to automatic guns in which there is included an apparatus for increasing the rate of fire of the gun. The breech mechanism of the gun is controlled by means of recoil movements which arise on discharge of the gun and by an operating cam (5) and spring member (7) included in the mechanism. Two case ejectors (18) are disposed to arrest the breech block (2) in the region of total recoil position of the breech and to hold the breech block in the open position in order thereby to make for ramming-home of a new round (19). In the arrested position of the breech block, the ejectors are exposable to the new round during its ramming cycle. A portion of the kinetic energy inherent in the round is transmitted to the ejectors which, in such an instance, may accompany the round and release the breech block so that this is actuated towards its closed position by the spring member (7). The operating cam (5) is movably disposed at least when the breech is located in the region of its total recoil position. The spring member may, in this manner, begin to actuate the breech block on its movement towards the arrest position at an earlier stage than has hitherto been possible.

Abstract: The invention relates to a method for controlling brushless d.c. motors and to a system for controlling such motors, by varying the effective value of current pulses to the phase windings. According to the invention, upon detection of a maximum current state the effective value is decreased by shortening pulses from a given time point (Ö1-Ö5) by the whole of the normally remaining part of the pulses, irrespective of whether the maximum current state ceases during the time that this part of the pulses should have occurred or not. This time point may coincide substantially with the time point at which the state of maximum current was detected or may coincide substantially with the later time point at which the duration of respective pulses exceeds a pre-determined minimum value. The next part-pulse is introduced at the time point at which it should normally have been introduced.

Abstract: The invention relates to carbon membranes for the separation of gaseous species from each other and to a process for the production of these. The membranes have uniform pore sizes of a predetermined size, with a very sharp upper size cutoff. The membranes are produced from carbon containing non-melting material in sheet form by strictly controlled pyrolysis at a certain rate of increase of temperature per unit time, in a inert atmosphere. The thus obtained membranes can be treated by heating in an oxidizing atmosphere at elevated temperature to modify pore size. The final product can be exposed to a further treatment by means of air, hydrogen or carbon dioxide, and if desired to vacuum treatment. The starting material an be pretreated with certain materials to increase dimensional stability and increase carbon yield.

Date Jun. 1, 1989.The present invention relates to a method to measure the angle of incidence for radiation and a detector to carry out the method. The background for the invention is that in certain electromagnetic radiation, for example laser light of different wavelengths from UV to IR, there occurs an irregularity, speckledness, that is among other things caused by turbulence in the atmosphere. This phenomenon gives rise to problems during the registration of a single or a few short pulses of radiation. Difficulties to reliably determine the angle to the source of radiation with high resolution can arise. This problem is solved by the invention by mounting two detector elements (1,2) so close to each other that both detector elements receive essentially the same irradiance and in such a direction that the normals of respective detector element form a known angle ( beta ) with each other. One then calculates the angle of incidence ( alpha ) by means of the signals (S1,S2) from the detector elements (1,2), that depend on the shape of the sensitivity beams, and said angle ( beta ) between the detector elements.
