Title: An adaptive detection method for quantized signals
Inventor: KOHONEN TEUVO
IPC: H04L25/02
Filed: 1990-08-20
Abstract: The invention is generally concerned with an adaptive detection method for quantized signals having nominal values which at different moments define a finite set of discrete states, wherein the discrete state of a signal at a certain moment is interpreted by comparing the sample value of the signal to a set of reference numbers, on the basis of which the recognition of the signal state takes place. According to the principle of the method the values of the reference numbers used in the detection are corrected adaptively towards the actual signal states of the signal to be detected by, e.g., a k-means clustering method or by self-organizing feature maps.

Title: Temperature control in a circular knitting machine
Inventor: SCHINDLER HARTMUT
IPC: D04B35/30
Filed: 1990-11-22
Abstract: A circular knitting machine comprising a carrier (1) for knitting implements (3) and a cam arrangement (11) has a heat exchange apparatus for the production of uniform temperature conditions the apparatus comprising two circuits (18 to 28 and 31) of which one is associated with the carrier (1) and the other with the cam arrangement (11) and which have a liquid heat exchange agent, preferably water, flowing through them. The uniform temperature conditions are achieved by the heat exchange output of at least one circuit being so controlled that substantially the same temperature difference obtains between the carrier (1) and the cam arrangement (11) in all operating conditions of the circular knitting machines. This is achieved by controlling a valve or the like supplying the relevant circuit, which may be done in a feedback manner by sensing the temperatures of the carrier and cam arrangement or by sensing the gap (S) between them. The carrier may be cooled by spraying as shown or by an embedded conduit like the conduit (31) of the cam arrangement. <IMAGE>

Abstract: 906,046. Moving coil instruments. ENGLISH ELECTRIC CO. Ltd. Dec. 10, 1958 [Dec. 16, 1957], No. 38990/57. Class 37. The magnetic system of a moving coil instrument comprises an outer yoke 15 connected by two closely-spaced legs 13, 14 to an inner pole 12 which, in conjunction with a polepiece 16, defines a part-annular air gap; one of the legs 14 being integral with the yoke 15, and the other 13 being connected thereto by a ferromagnetic link 18. Magnets 17 are secured by a synthetic resin adhesive between polepiece 16 and locating recesses 17a in the yoke 15, with like poles facing each other, to complete the magnetic circuit. Pillars 5, bolted through rubber bushes 7 to a plato 6, extend through the magnetic system to support a movement holder 23 carrying lower and upper bearings 25, 27 between which extends a staff 28 carrying a moving coil 29. Removal of link 18 enables arm 24 of the movement holder 23 to pass through the gap so formed whereby the assembled movement, including the coil 29, may be removed from the magnetic system. An eccentric peg 39 of a zero adjustment knob 4 engages a slot in a sliding member 40 from which a peg 43 extends to engage a frictionally mounted toothed wheel 37 secured by a depending tongue 36 to one end of the usual controlling hair spring 35. For use as a dynamometer, Fig. 3 (not shown), the magnets 17 are replaced by energizing coils mounted upon projecting arms of the polepiece 16; and a coil mounted upon leg 13 compensates for flux induced in the system by the moving coil 29. Specifications 906,044 and 906,045 are referred to.

IPC: G21C7/14
Filed: 1992-01-16
Abstract: A method and apparatus are provided for passively cooling the control rod drive mechanisms (CRDMs) 4 in the reactor vessel of a nuclear power plant. Passive cooling is achieved by dispersing a plurality of chimneys 3 within the CRDM array in positions where a control rod is not required. The chimneys induce convective air currents which cause ambient air from within the containment to flow over the CRDM coils. The air heated by the coils is guided into inlets 25 in the chimneys by baffles 21. The chimney is insulated and extends through the seismic support platform 2 and missile shield 10 disposed above the closure head. A collar 16 of adjustable height mates with plate elements 12 formed at the distal end of the CRDM pressure housings by an interlocking arrangement so that the seismic support platform provides lateral restraint for the chimneys. <IMAGE>

Title: Optical communications system
Inventor: RARITY JOHN GILROY
IPC: H04B10/70
Filed: 1993-02-03
Abstract: An optical communications system (10) comprises a transmitter (12) and a receiver (14). A source (16) of correlated pairs of photons of conjugate energies provides first and second photon beams (38, 36). The first photon beam (38) passes through a modulated filter (50) to which a communications signal (52) is applied. A variable spectrum beam (54) is produced which is converted to a timing signal (68) of macroscopic optical pulses (66). The second photon beam (36) and timing signal (68) are transmitted to the receiver (14). The received timing signal (84) is converted to a series of electrical timing pulses (90). The received second photon beam (62) passes through an unmodulated filter (94) matched to the modulated filter (50) when the signal (52) is not applied. The unmodulated filter splits the beam (82) into two conjugate spectra photon beams (96, 98) which are then converted to first and second series of electrical pulses (108, 110) respectively. The pulses (90, 108, 110) enter a coincidence counter (92) which records coincidences between the timing pulses (90) and the first series of pulses (108) and between the timing pulses (90) and the second series of pulses (110). Two coincidence rates are obtained and subtraction of one from the other yields an output communications signal (112). <IMAGE>

Title: Trim for bridging floorcoverings of different thicknesses
Inventor: LAW JOHN GRAHAM
IPC: A47G27/04
Filed: 1993-03-26
Abstract: A one-piece trim (1) for bridging two floorcoverings of different thicknesses comprises a rigid length of material of uniform stepped cross-section. The trim (1) defines a base portion (2) which can be secured to a subfloor and over which the thinner of the two floorcoverings can be located to abut a riser (3) of the step. Projecting outwardly on the opposite side of the riser (3) to the base portion (2) is a binder (4) beneath which an edge of the thicker of the two floorcoverings can be located. The thickness of the base portion (2) adjacent the riser (3) is adapted to be such that the top surface of the thinner of the two floorcoverings is brought to substantially the same height as that of the thicker when laid thereon. The thinner of the two floorcoverings may be secured to the trim by adhesive. The trim thus provides a comparatively inexpensive and safe way of bridging the transition between the floor coverings. <IMAGE>
