Abstract: 1417386 Controlling asynchronous motors SIEMENS AG 7 Aug 1974 [9 Aug 1973] 34891/74 Heading H2J An asynchronous motor 1 and supply circuit comprises a main winding 2 and an auxiliary winding 3 both connected to a polyphase A.C. source such that the voltage applied to the windings has a predetermined phase difference, preferably 120 degrees, and a controllable switching means, e.g. a triac 5, connected to control the phase of the current in the auxiliary winding 3 together with control means 6 for the switch so that when the predetermined phase difference exists, the phase of the current in the auxiliary winding 3 leads by approximately 90 degrees the phase of the current in the main winding 2. The conduction angle of triac 5 is preferably maintained constant. A further triac 4 may be provided in line with the main winding 2 and its firing angle may be dependent on the difference between a desired motor speed signal from controller 9 and an actual speed signal from tachogenerator 8.

Abstract: The invention relates to the use of a sulphated ion exchanger to selectively remove lipoproteins from blood plasma or serum. Although the attraction between sulphate groups and proteins has long been recognized it has now unexpectedly been found that cationic ion exchangers whose ion exchange capacity is provided by sulphate groups bind lipoproteins selectively in presence of other plasma or serum proteins and ions when they are equilibrated with solutions containing divalent cations and the same cation is added to the plasma or serum. Types of ion exchanger matrices and applications of the utlity are discussed.

Abstract: A method and apparatus for measuring the thickness corrected moisture ratio of a material, particularly organic material, comprising transmitting microwaves and measuring therewith the damping (A) and phase change (F1) of the microwaves upon their transmission through the material. According to the invention (Ww/Y) is calculated from the expression A=(Ww/Y)x xk1+k3xt, where t is the thickness of the material (10) and where k1 and k3 are constants and the term Ww/Y is the weight of the water in the material per unit area. In addition, the term (Wd/Y) is determined from the expression F1=(Ww/Y)xk4+(Wd/Y)xk5+k6xt in which expression the aforedetermined term Ww/Y is used. The term Wd/Y is the weight of the material in a dry state per unit area and k4, k5, k6 are constants. The moisture ratio is obtained in a known manner through the quotient (Ww/Y)/(Wd/Y). In this way the effect of the material thickness on damping (A) and phase change (F1) is included in the determination of the moisture ratio of the material.

Abstract: The invention relates to a process for the preparation of rye starch from dry rye flour products, preferably from impact-ground rye flour. In order to separate the starch, the ground rye product, water, process water and/or aqueous recirculated medium are combined to give a ground product suspension having a hydraulic modulus of 4.0-0.8, preferably 2.0-0.8. The aqueous ground product suspension is subjected to vigorous mechanical agitation, and at the same time 0.05-0.15 of SO2 are metered in. The acidified suspension is subsequently warmed to a temperature of 25-50 DEG C, preferably 30-48 DEG C, incubated with Lactobacilli, Streptococci, sour dough extract or sour dough pure cultures for viscosity treatment and subjected to long-term treatment for a period of 5-24 hours. The crude starch is separated off from the viscosity-reduced ground product suspension by classification in a centrifuge field and then resuspended, sieved and refined. Mild alkali treatment allows the protein content of the refined starch to be reduced from 0.3-0.4% to 0.12-0.15%.

Abstract: A light level controller includes a microcomputer controlled light switch which responds to a manual tap or a longer manual depression of the switch in order to initiate various control modes for a light source. Preset levels of light intensity may be stored in the microcomputer's memory and an automatic fade mode may be initiated to cause the level of light intensity to fade from a current level to a preset level at a pre-established rate. The controller may respond to the momentary depression of the switch to initiate the automatic fade mode or if tapped while a fade is in progress it may cause the light source to make an abrupt transition to either full on or full off, depending on whether a higher or lower level of light intensity is desired. A depression of the switch for a period longer than a tap will cause the level of light intensity to continue to change until the switch is released, and simultaneously this level will be stored in memory.

Abstract: A process for accurate measuring of the rotational angle of a rotating object comprises the following procedural steps: a pulse emitting unit (3) produces a signal S1 consisting of pulses at a frequency f1 dependent upon the rotation of the object, an oscillator (4) emits a signal S2 consisting of pulses at a frequency f2 substantially larger than f1 and a measuring signal transmitting unit (5) produces a signal S3 indicating instants of beginning and of ending, respectively, of a rotational angle measurement. According to the invention, a counter (R1) in a calculator unit is caused to count pulses of the S1 signal, that is, periods for each revolution of the object, a counter (R2) counts pulses of the S2 signal for every period in the signal S1. At a first and a second impulse, respectively, of the signal S3 a first memory (M1) stores the number of S1 pulses = M1a and M1b, respectively, a second memory (M2) stores the sum of the S2 pulses, M2a and M2b, respectively, while a third memory (M3), at the end of the first period of S1 after the respective first and second impulses of S3, stores the sum of the S2 pulses during an S1 period = M3a and M3b, respectively, whereupon a calculating unit B1 calculates a value V1 related to the measured rotational angle from M1b + M2b/M3b - M1a - M2a/M3a.
