Abstract: ABSTRACT OF THE DISCLOSURE           An output voltage of an AC generator is produced through a full-wave rectifier and converted into a digital signal by an A/D converter.  This digital signal is compared with a reference signal, and in accordance with the difference therebetween, the firing angle of a thyristor is controlled to regulate the field current.  Synchronous point detectors detect a synchronous point of the output voltage of the AC generator.     A microprocessor computes a firing angle of the thyristor in accordance with the difference between the digital signal and the reference signal and produces a signal representing the computed firing angle upon detection of the synchronous point.  The thyristor is fired at the firing angle computed by the microprocessor.

Abstract: ABSTRACT      A safety valve intended to limit the pressure of a fluid contained in a vessel to which the valve is connected by a nozzle closed off by a flap-valve pressed against its seat by a spring acting on a first side of the flap-valve.  The valve has two operating states, either the flap-valve is closed when the fluid pressure in the vessel acting through the nozzle in the opposite or second side of the flap-valve is below the pre-determined value or the flap-valve is open allowing fluid from the vessel to escape via an escape chamber in the valve when the pressure in the vessel is above the pre-determined value.  A casing surrounding the spring is connected with the escape chamber by calibrated holes whereby the pressures in the casing and chamber are equalised.  In addition to the spring, fluid pressure in the chamber acts on the first face of the flap-valve. When the flap-valve is closed, the fluid pressure in the escape chamber and casing is low.  Thus the flap-valve opens quickly when the fluid pressure in the vessel attains the pre-determined value.  When the flap-valve is open the pressure in the escape chamber and thus in the casing is high assisting rapid closure of the flap valve when the vessel pressure falls below the pre-determined value.

Abstract: DIFFRACTIVE SUBTRACTIVE COLOR FILTER  RESPONSIVE TO ANGLE OF INCIDENCE OF  POLYCMROMATIC ILLUMINATING LIGHT                           Abstract A diffractive subtractive color filter (Fig. 1) includes a variable index-of-refraction optical medium (100) of certain minimum thickness (t) and periodicity (d) with respect to the wavelength of incident light.  The filter meets certain specified constraints with respect to:  (1) relative indices-of-refraction of both its internal structure and that of its surroundings (114, 116), (2) relative values of incident wavelength to periodicity and (3) the relative indices-of-refraction of the optical medium and its surroundings and operates to produce both angularly-dependent subtractive-color filter reflection spectra and subtractive-color filter transmission spectra in accordance with its physical parameters.  Such filters are suitable for use as authenticating devices for sheet-material authenticated items.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to a method for producing foodstuffs from whole cereal grains. The grains in aqueous phase are subjected to an enzyme treatment to solubilize the starch content of the grains.  The grains in dry form are added to the aqueous phase simultaneously with the enzyme used, and the temperature of the aqueous phase is such that before the enzyme is sterilized only dextrins and oligosaccharides are formed.  The method is an improvement in that the formation of sugar-protein compounds, such as gluco-proteins, is avoided.  The solid phase products obtained can be used as a meat substitute, and the liquid phase products obtained, can be further de-composed to sugars of different kinds.

Abstract: Abstract:        A microporous filter system comprises two types of hydrophilic, microporous filter media operating in series. The two filter media have opposite zeta potentials with the upstream or first filter medium preferably having the positive zeta potential and the downstream or second filter having the negative zeta potential. The first filter medium typically has an absolute pore rating of from about 0.1 to about 1.0 micrometer and the second or downstream filter medium typically has an absolute pore rating of from about 0.02 to about 0.1 micrometer. The downstream or second filter has a finer absolute pore rating than the upstream or first filter. Fluids contaminated with ultrafine particles can be purified with an essentially absolute efficiency to remove 99.99 per-cent or more of the particulate matter in the con-taminated fluid. The filter system finds particular use in the preparation of ultrapure effluent water of near theoretical resistivity and in the removal of bacteria and endotoxins to form sterile fluids.
