Title: Magnetic circuit of transformer station having unbroken cross-section without saturation on the joint of sheets
Inventor: ISIDOROVIC RATKO
Filed: 1997-12-05
Abstract: Magnetic circuit of transformer station having unbroken cross-section without saturation on the joint of sheets improves a degree of exploiting the transformer station, i.e. it reduces loss of energy in magnetic circuit for 20% and circuit of idle motion 45 %, thus the transformer stations are budget-priced and have lower price. The width of sheets of the column and the yoke and the angle of cutting gives the equation of saturation on the joints of the column and the yoke. These angles can have constant values, as the most often value of induction in the column is 1,7 T. For Te angles for this value are 52° and 38° and the 'V' slit is 76°. So as to exploit the automatic machines with 'V' stamping in 90° magnetic circuit is possible in an embodiment with a slit of 90° upon reducing the loss on the joint of the central column with yoke. These losses can be reduced if the middle column gets connection to the yoke in a step-lap way. Moreover, the apertures punched in the yoke sheet, reduce the total loss.

Title: Veneer strip prodn. method - uses sheets cut along corrugated lines across grain with wavelength of strip width
IPC: B27D1/10
Filed: 1982-03-29
Abstract: The method produces veneer strips, using veneer sheets cut across the grain along a corrugated line. The corrugation wavelength pref. coincides with the width of the small strips cut out from the sheet along the grain. The corrugated line can be formed by a milling cutter. The corrugation can be nearly sinusoidal, and between the curves there can be a straight portion parallel to the grain. The method allows a large number of strips to be cut out at the same time.FL.

Abstract: ABSTRACT OF THE DISCLOSURE           This safety ink is useful for printing a background of fine lines or dots on a document of value, such as a bank check.  The background extends over an area which is adapted to be written upon.  If the area in question is written upon and an attempt is thereafter made to eradicate the writing, the back-ground changes color, thereby making it obvious upon visual inspection that an attempt has been made to alter the writing. The ink includes a dye which is soluble and bleachable and a fluorescent pigment whose fluorescence is enhanced if the attempted alteration is by means of a dissolving or bleaching technique, so that removal of part of the dye results in a change in color and also in an enhancement of the fluorescent intensity of the remain-ing printed matter.  If an attempt is made to alter the writing by erasure, rather than eradication, some of the fluorescent pigment is removed, and its fluorescent intensity is consequently decreased.  Hence, an attempted alteration  is detectable either under ordinary light by the change in visible color or under ultra-violet light by the change in the fluorescent intensity.

Abstract: ABSTRACT OF THE DISCLOSURE           A coke oven battery for optional heating by means of lean gas or rich gas with twin flues disposed in a row between the ovens.  The present invention proposes a construction of a coke oven battery which is to be optionally heated with rich gas or lean gas and has a regenerative heating system to provide firstly a particularly low flow resistance and secondly the least possible content of nitrogen oxides in the smoke gas.  In this way, the recent demand for minimizing the amount of nitrogen oxides in burnt gases which are discharged to atmosphere is met.          According to the subject invention, two cross-regenerators are disposed below each oven and are biased over their entire length in the same sense and with ducts disposed in the transverse walls and having a graded arrangement of the exit ports.  One of the regenerators serves alternatively for preheating the air and communicates with header flues of both adjacent rows of heating flues and the other, when heated with lean gas, serves alter-natively for the preheating thereof and when heated with rich gas serves for preheating the air and communicates with exit ports on the sole of the heating flues of both adjacent heating flue rows and the sequence of the upgoing and downgoing flues alternates from heating flue row to heating flue row.

Granted: 1979-12-18
Abstract: ABSTRACT        Diversity reception techniques are known in radio communication systems.  When reception is switched from one propagation path to another an instantaneous signal interruption is caused at the receiver output which is highly undesirable in the case of digital signal transmission.  The present invention alleviates this problem by providing a digital signal gate switch for selecting one of a plurality of digital signals and a clock signal gate switch for selecting one of a plurality of clock signals extracted from the respective digital signals.  A delay circuit delays the clock signal selected by the clock signal gate switch.  A control signal read-out circuit is arranged to be fed with the output of the delay circuit to read out a switching control signal, separately fed to the control signal read-out circuit so that the digital signal and clock signal gate switches are contro-lled simultaneously by the output of the control signal read-out circuit.
