Title: Thread, more particularly sewing thread, as well as a  method and apparatus suitable for producing such thread
Inventor: BUTZHEINEN KARL-HEINZ
IPC: D02G1/16
Filed: 1988-05-27
Granted: 1994-06-28
Abstract: ABSTRACT         Thread, More Particularly Sewing Thread, as well as a Method and Apparatus Suitable for Producing such Thread.       Threads comprising one or more main filaments bonded together by a melt bonding filament admit with difficulty the formation of sufficiently solid bonding and the maintenance of essential thread properties. The production of such conventional threads furthermore requires heavy twisting. The invention, developed to remedy these deficiencies, provides the main strands formed of a multifilament filament strand comingle with one or more bonding filament strands to cause the occurence of loops and bends which, when diffused through the strand cross section, promote a very effective bond while other normal thread properties are retained.

Abstract: Abstract A marine drive unit     includes a lower gear case     forming a torpedo housing    .  A pair of coaxial propeller shafts          are rotatably mounted in the housing and carry a pair of propellers thereon.  The propeller shafts are driven by a pair of opposed driving gears          suitably connected through a generally vertical main drive shaft    to a marine engine     and mounted on the horizontal drive axis     .  A pair of thrust bearings          adapted to carry forward thrust loads are respectively disposed adjacent the facing portions of the opposed driving gears, with the pair being separated by a spacer tightly confined therebetween.  The spacer is locked against rotation but is freely floatable in an axial direction, and transfers the forward thrust load from one bearing to the other, so that the load is ultimately transferred from the outer propeller shaft to the inner central shaft     .  The result is to reduce the rotational speed of each thrust bearing, in this instance by half.

Abstract: ABSTRACT           A circuit for controlling the power dissipated by an electrical resistance coupled to a supply voltage which varies, includes a feedback circuit, coupled to the electrical resistance, for producing a feedback current corresponding to the current flowing through the heater.  A correction circuit produces a correction current corresponding to variations in the supply voltage.  An integrator receives the correction current and the feedback current and amplifies the error indicated by the correction current and the feedback current.  A pulse width modulator receives the amplified error and controls the ON time of a switching device to control the flow of current through the electrical resistance.  The flow of current through the electrical resistance is controlled to maintain the power dissipated by the resistance constant.

Abstract: Abstract of the Disclosure A stationary gasifier (17) is located at a distance (49) from an air aperture plate (35). At the outlet (42) of the gasifier there is a stationary mixing head (29) having a deflector section (31) and lateral outlets (33). Inside of the gasifier (17) is an insert (57) of metal cloth. Fuel supply takes place coaxially through an opening (55) of the air aperture plate. The gasifier (17) is surrounded by an electric heater (39).   A flame tube (21) surrounds the gasifier (17) and the electric heater (39) at a distance. The annular space (40) provides a recircu-lation path for hot combustion gases. When the burner is started up, the electric heater (39) is switched on until the gasifier has the necessary operating temperature. Only then the supply of fuel begin.       The fuel/air-mixture is ignited by an electrode (65). Then a flame is formed at the outlets (33) that touches, after a short travel, the flame tube, then emerges from it  and expands. Because the flame can immediate-ly expand, only  little NOx is formed. A portion of the hot combustion gases is recirculated by the action of the air flowing through the air aperture plate. The recirculated combustion gases are sucked into the gasifier and serve to heat the gasifier (17) after the shutoff of the electric heater (39).                                          (Fig. 2)

Abstract: (1) ABSTRACT OF THE DISCLOSURE     The present invention adopts as the basic structure of its thermomagnetic recording medium an arrangement consisting of a first and a second magnetic thin film having perpendicular anisotropy and a third magnetic thin film having in-plane magnetic anisotropy or small perpendicular magnetic anisotropy interposed therebetween, formed into a laminated structure by being magnetically coupled to the adjoining films in turn, modulates and switches, in accordance with information to be recorded, a first heating condition and a second heating condition, with the medium applied with a predetermined external magnetic field Hex in the direction perpendicular to the plane of the film, the first condition being that for raising temperature of the medium to a first temperature T1 which is virtually above the Curie temperature TCl of the first magnetic thin film and not causing reversal of the magnetic moment in the second magnetic thin film and the second condition being that for raising temperature of the same to a second temperature T2 which is virtually above the Curie temperature TCl and sufficient to cause reversal of the magnetic moment in the second magnetic thin film, (2) to thereby form an information bit (magnetic domains) in the first magnetic thin film, and adapts during the course the medium is cooled from the heated states such that two states established by the different relationships between the directions of magnetization of the first and second magnetic thin films are finally formed whereby the recording of the information is performed, and thus the present invention brings about conditions enabling alteration of recorded information to other information, that is, enabling so-called overwriting.  Especially, by virtue of the third magnetic thin film, the present invention achieves simplification of the apparatus for applying the magnetic field.

Abstract: AREA-MODULATED LUMINESCENCE (AML) ABSTRACT OF THE DISCLOSURE        A luminescence measuring system is provided for detecting luminescence at extremely low concentrations of luminescing moieties.  The method employs alternating radiation at a plurality of loci of an inhomogenous solution, where the radiant power is maintained constant, and the irradiated volumes of pairs of loci are systematically varied.  With the probability being very low that the same luminescence signal will be obtained in the two or more measurements, by comparing the measurements, one can detect a low luminescence signal in the presence of relatively high noise levels.  Various techniques are described for modulating the irradiance and detecting changes in signal.
