Abstract: A device for monitoring the thread supply in a thread-feeding device for textile machines has two measuring circuits (55, 56), of which one processes signals characterising the rotational movement of a rotatable element, for example a thread-feed roller (4), coupled in a non-slip manner to the thread (16) and the other measures the set desired thread-tension value of a desired-value transmitter (22) of a control circuit assigned to the thread-feeding device. The two measuring circuits are assigned indicator means (66, 71) which are calibrated directly in units of thread length and/or thread running speed or thread tension and to which output signals from the first and the second measuring circuit respectively are supplied. <IMAGE>

Abstract: A microwave band pass filter (20) for filtering electromagnetic signals has a set of cavities (60) arranged serially, with a block (62) of dielectric material filling each cavity (60) to define regions of each cavity (60) which are loaded with dielectric material and regions (64) which are free of the dielectric material. Each cavity (60) may be viewed as a resonator for a fundamental mode of propagation of an electro­magnetic wave while each block (62) can be viewed as a resonator for higher-order modes of propagation of electromagnetic power. The cavities (60) are separated by walls (72) having slots (74) aligned with the free regions (64) of the cavities (60) for coupling power from the fundamental mode while minimizing interaction with power of the higher-order modes. The filter (20) enables the construction of an enlarged passband while inhibiting the presence of the spurious higher-order modes in a stop band bordering the passband.

Abstract: Apparatus for surface treatment of a synthetic organic polymer moulding includes a preliminary heating chamber (11) for heating a synthetic organic polymer moulding as a preliminary step, a solvent treatment chamber (21) for contacting the surface of the preliminarily-heated moulding with an ultraviolet light absorbing solvent provided in a solvent tank (25), an irradiation chamber (31) including low pressure mercury lamps (35) for irradiating the surface of the moulding with ultraviolet light having a main wavelength of 184.9 nm, and a transfer mechanism such as a belt conveyor (41) for transferring the moulding through the chambers. The apparatus can alternatively dispense with the preliminary heating chamber, in which case the solvent treatment chamber is arranged to contact the surface of the moulding with the ultraviolet light absorbing solvent having been heated to a predetermined temperature. 
     A polypropylene type resin is preferably used as the synthetic organic polymer. The surface of the synthetic organic polymer moulding is easily modified and hence coating, printing, adhesion, or similar treatment of the moulding can be effected with high adherence.

Abstract: A ceramic article is described having good fracture toughness comprising substantially spherical ceramic particles, which may be a ceramic oxide such as zirconia or zirconia combined with yttrium oxide. The ceramic particles are compacted and sintered to a density greater than 90 percent of theoretical density. The article is characterized by a substantially uniform chemical composition and a substantially inclusion-free, homogeneous microstructure, which may be a metastable crystalline phase with less than 10 volume percent monoclinic crystalline phase. The article is produced by dissolving, such as in water, a soluble compound containing a metal, e.g. zirconium, to form a solution. A precipitation agent, such as sodium hydroxide or ammonium hydroxide, is combined with the solution to precipitate a hydrophilic colloid of the metal hydroxide, such as zirconium hydroxide. The precipitate is formed into particles which are rapidly solidified while preventing agglomeration thereof. The particles are dried, compressed to increase density and reduce size, calcined to convert the metal hydroxide to oxide, e.g. zirconium oxide, and then the particles are compacted and sintered to form a dense ceramic article.

Abstract: The magnet (12) creates a main magnetic field along a z-axis through an image region. A localized coil (D) is disposed in the image region at least to receive magnetic resonance signals from nuclei of the subject which have been induced to resonance. The localized coil (D) includes an inner conductor (30), an outer conductor (32), and a dielectric material (52) therebetween. The outer conductor defines a gap (50) midway between its ends. One end of the inner conductor (30) is connected with a gate of an FET transistor (66) and the outer conductor (32) is connected with its source. The transistor source and drain are connected by a coaxial transmission cable (38) with a DC power supply (70) which provides a DC bias across the transistor source and drain. The cable (38) also connects the transistor with a radio frequency receiver (40) to convey preamplfied magnetic resonance signals thereto. The other end of the inner conductor (30) may be connected with the outer conductor (32) to provide an unbalanced localized coil or the ends may each be connected with an FET transistor (66a,66b) in a balanced coil arrangement.

Abstract: An apparatus for providng a continuous underground tunnel utilizes an elongate boring device (14) including a forward facing, off-axis high fluid jet (36) which is rotated about the axis (63) of the device (14) while the latter is urged forward through the soil, thereby to cause the device (14) to bore a tunnel through the soil as it moves forward. The boring device (14) is steered by modulating the speed and/or the direction of rotation of the off-axis fluid jet (36) in a way which depends upon the desired direction to be taken by the boring device (14) within the soil. The pitch angle of the boring device (14), as defined by its axis (63), is monitored relative to a horizontal ground plane, independent of the roll position of the device (14). The roll angle of the boring device (14) and the position of its off-axis jet (36) are simultaneously monitored thereby to monitor the precise rotational position of the jet (36) relative to its roll position.
