Abstract: 1. Start device (8, 9, 11, 25, 26, 29) for a controlled or regulated asynchronous machine (1) wherein the stator winding is fed by a controllable rectifier (2) and the field orientated control or regulation unit contains : a) a flux detective device (3, 4, 5) which forms output values (cosphi, sinphi) corresponding to the particular position of the magnetic main flux vector (Fr, Fj) of the asynchronous machine relative to a stationary reference vector in the stator and b) a co-ordinate converter (6) which is supplied with the output values from the flux detection device (3, 4, 5) and which converts two input values (b, w) which correspond to the components of a predetermined vector relative to the particular position of the main flux vector into control values (I*R , I*S , I*T ) for the rectifier which are such that in the event of a change in one component (b) of the predetermined vector, only that component (Ib) of the stator current which is parallel to the main flux vector is influenced, and in the case of the other component (w) only that component (Iw) of the stator current which is perpendicular thereto is influenced, characterized by a swither-over device (8, 9, 11) by means of which, prior to the start of the asynchronous machine, the co-ordinate converted (6) is supplied temporarily not with the output values (cos phi, sin phi) of the flux detection device (3, 4, 5), but with values (Va, Vb) which correspond to a predetermined position of the main flux vector and which moreover keep that input value (w) which influences the component (Iw) of the stator current which is perpendicular to the main flux vector at a value (w' = 0) which serves to limit to zero the component of the stator current which is perpendicular to the main flux vector.

Abstract: A semiconductor integrated circuit device of an 1 2 L type is disclosed. The bit lines (Bo,  B o, B 1 ,  B   1 ) are supplied with a clamp circuit (CL,) which supplies non-selected memory cells with sink currents. In order to ensure that the potentials of the bit lines are clamped at a level between the upper and lower limits dictated by the requirements for fast writing and the retention of information, the clamp circuit incorporates one or more dummy cells (DC,) which are similar to the memory cells (CELL). Variations in their manufacture will cause the characteristics of the dummy cells (and hence the said limits) to vary in the same way as those of the memory cells. Therefore the clamp voltage level can be set close to one or other of the said limits in the assurance that the level will always be within the limits.

Abstract: To watch the performance of a condenser, cooling water temperature, cooling water flow rate, condenser temperature and/or heat flux through walls of cooling water tubes of the condenser are sensed by sensors (16,18,19,20,21,22,23,24) to obtain values representing the operating conditions of the condenser. The overall heat transmission coefficient or heat transfer rate of the cooling water tubes is calculated by an arithmetic unit from these values. The cleanness of the cooling water tubes is calculated by an arithmetic unit from the overall heat transmission coefficient or heat transfer rate, and the performance of the condenser is judged by a performance judging unit based on the cleanness of the cooling water tubes. Good and continuous monitoring of the condenser can be achieved.

Abstract: In a sewing machine with electronic pattern data circuits for the generation of signals used for sewing fancy seams it is possible to save spacing in the data memory by dividing the fancy seams into seam elements of several stitches so that every seam is composed of a plurality of seam elements and one and the same seam element is part of several fancy seams. 
     A sewing machine utilizing the seam element principle must have two different memories, one stitch memory storing every element stitch by stitch and one seam instruction list storing for each fancy seam the sequence of seam elements forming the selected seam.

Abstract: A service integrated transmission system for transmitting, over a light transmission path, digital signals having a transmission band whose upper limit frequency corresponds to the maximum bit rate of the signals to be transmitted, the transmission being effected by simultaneously transmitting, over the transmission path, digital signals having a high bit rate only in an upper part of the transmission band and digital signals having a low bit rate only in a lower part of the transmission band. The system includes a transmitter at one end of the path which separately multiplexes low bit rate signals into a narrowband signal and high bit rate signals into a broadband signal, combines those multiplexed signals, and modulates a light source with the combined signal. A receiver at the other end of the path converts the modulated light signal into a demodulated electrical signal, separates the two multiplexed signals, and then demultiplexes each of the latter signals.

Abstract: The phase-locked loop section (10, 14) of the synthesizer is periodically disconnected from the battery supplied power by means of a switch (60). In order to prevent substantial drift of the phase-locked loop during such power interruption, means (22, 24) are provided for maintaining a control signal on the VCO (12) associated with the loop (10) that maintains the VCO frequency. By minimizing the frequency drift, the loop can be re-locked in a short period of time following each power interruption.

Abstract: An electrically conducting acrylic or modacrylic fibre is impregnated with 1 to 30 wt. % of copper sulfide, e.g. digenite. 
     A two-step method of making these fibres comprises subjecting the fibres to a first heat-treatment in a bath containing a copper compound and a reducing agent to adsorb monovalent copper ions into the fibre, and subjecting the fibre to a second heat-treatment in the presence of a sulfur-containing compound to convert said adsorbed monovalent copper ions to copper sulfide. 
     An alternative one-step method comprises subjecting the fibre to heat-treatment in a bath which contains a copper ion compound, a reducing agent which is capable of reducing copper ions to monovalent ions, and a sulfur-containing compound to convert monovalent copper iions to copper sulfide. 
     The electrically conducting fibres have superior conductivity, which is not lost in repeated washing, can be dyed readily with cationic dyes without loss of electrical conductivity and possess the touch and other physical characteristics of the starting acrylic or modacrylic fibres.
