Title: Device for direct measurement of frequency
IPC: G01R23/09
Filed: 1950-01-06
Abstract: 667,589. Frequency measurements. KRIZIK, NARODNI PODNIK, and CIGANEK, J. Jan. 6, 1950 [Jan. 6, 1949], No. 452/50. Class 37. A device for the direct measurement of the frequency of an alternating voltage, or of pulses generally, consists of a trigger circuit and of a differentiating valve connected thereto. Two valves I, II, Fig. 1, are cross-connected as shown to form a trigger circuit. A differentiating valve III is connected through a condenser C2 to the anode of the valve II and has in its anode circuit a galvanometer G graduated in cycles per second. An alternating voltage applied to terminals VI, V2 is transformed by the trigger circuit into a rectangular wave, which is differentiated by the valve III giving current pulses of exponential shape and of constant amplitude and duration. The number of pulses per second is the same as the frequency to be measured, so that the mean current through the galvanometer G is proportional to the frequency. In order to increase the sensitivity a further trigger sweep circuit may be added as shown in Fig. 5. The galvanometer G in the anode circuit of the differentiating valve III is replaced by a resistance R3, the output pulses being applied through a condenser C4 to the grid of a valve IV which is connected to a valve V as shown to form a trigger sweep circuit, which returns to its quiescent state as soon as the. pulse applied to the grid of the valve IV has passed. Rectangular pulses of constant amplitude and duration are produced and can be measured by an instrument connected to terminals A, B. The apparatus may be used for the direct determination of the sum of a plurality of values to be measured by using the same number of receivers as the number of values to be measured. The valves III of these receivers are connected in parallel to a single galvanometer, which shows the total of the individual frequencies.

Title: Improvements in or relating to low voltage ignition systems and apparatus for reciprocating internal combustion engines
Inventor: WEST HAROLD EDWARD WILLIAM
IPC: F02P1/08
Filed: 1950-01-11
Abstract: 694,100. Ignition systems; sparking plugs. ROLLS-ROYCE, Ltd. March 14, 1951 [Jan. 11, 1950], No. 778/50. Class 7 (iv). Ignition Circuits In an ignition system comprising an enginedriven A.C. peaked-voltage wave-generator 10, Fig. 1, rectifier 11, and capacitor 12 to be charged by D.C. voltage impulses from the rectifier, lowvoltage sparking plugs 15 are provided which are connected to the capacitor through a jump-spark distributer 14 that is operated to connect the plugs with the capacitor in timed relation to the D.C. voltage impulses. The output from the generator 10 is supplied directly to two parallel circuits each comprising a rectifier 11 of the selenium type, for example, and a capacitor 12; the rectifiers are oppositely arranged to pass alternate halves of each cycle of the generator output. The common point between the rectifier and capacitor of one circuit, is earthed, and the corresponding point of the other circuit is led to the sparking plug 15 by the distributer 14. The generator mav give one, or more than one, voltage impulse per 30‹ of distributor revolution, i.e. between successive distributer contacts. In a modification, a single capacitor is employed with a bridge arrangement of four rectifiers, the capacitor receiving one charge from one of the two pairs of bridge arms between each discharge; should the charge on a capacitor be 'insufficient to enable it to discharge across the distributer, the charge is reinforced by successive impulses until it can bridge the distributer gap. The Provisional Specification describes an ignition circuit in which the generator is of the lowtension inductor type with an earthing coil and switch, which, when closed short-circuits the earthing coil and stops the operation of the magneto; a D.C. impulse generator may alternatively be employed: Sparking Plugs Each sparking plug. comprises a centre electrode 20, Fig. 4, and an annular electrode 21, the space between the two electrodes being filled with insulating material 22 whilst the periphery of the protruding part of the latter is treated to form a semi-conductor 23 with a negative temperature co-efficient of resistance. When a voltage is applied to the plug a current flows through the semi-conducting surface 23; the distribution of the current becomes unstable and a large part of the current passes through a small section of the surface 23 which section heats up so that its resistance decreases until a glow condition occurs which enables the capacitor or capacitors to completely discharge therethrough.

Title: Improved method of recovering calcium lactate and lactic acid from fermented mashes
IPC: C12P7/56
Filed: 1940-01-15
Abstract: 538,060. Lactates ; lactic acid. MULLER, J. Jan. 15, 1940, No. 875. Convention date, Jan. 20, 1939. [Class 2 (iii)] Alkaline earth lactates are purified by dissolving in boiling strong ethyl, propyl or isopropyl alcohol, filtering and cooling to effect crystallization. The alcohol preferably contains 15-5 per cent. of water. The solution may be agitated while cooling to control the size of the crystals. When the lactate is produced by the fermentation of a mash in the presence of, for instance, calcium carbonate, alcohol of 95 per cent. (which may contain a denaturant such as 15 per cent. of acetone) is added to precipitate the lactate which is then purified by dissolving in boiling alcohol and crystallizing one or more times. Alternatively, the mash may be concentrated before treatment with the alcohol, or it may be evaporated to dryness and boiled with alcohol preferably of 80 per cent. strength with agitation, the solution being filtered and cooled for crystallization, further crystallizations being effected as before for purification. Lactic acid may be prepared from the purified lactate or from the alcoholic solution before crystallization, for instance by treatment with sulphuric acid. The Specification as open to inspection under Sect. 91 is not limited to the use of the alcohols specified, and mentions methyl alcohol as suitable. This subject-matter does not appear in the Specification as accepted.

Abstract: PURPOSE:To keep the concentration of an activated yeast fungus extremely high, and to prepare seasoning having improved flavor in a short time, by hydrolyzing a raw material for preparing soy sause, fermenting the hydrolyzed raw material, filtering the fermentation solution, returning the separated solution containing yeast  fungus to a fermentation tank. CONSTITUTION:A raw material for preparing soy sauce (e.g., one obtained by adding a  starchy raw material such as wheat, etc. to a protein raw material such as defatted  soybean, etc.) is enzymatically or chemically hydrolyzed, it in a state of liquid at 3.0- 7.0pH is introduced into a fermentation tank, a yeast for soy sauce is added to the hydrolyzed raw material, which is fermented in such a way that the average retention  time of the fermentation solution is made >=3hr, the fermentation solution is taken out  of the fermentation tank, and the hydrolyzed raw material at 3.0-7.0pH is fed to the  fermentation tank. The discharged fermentation solution is filtered by a filter (e.g.,  ultrafilter, etc.), and separated into a solution containing a mold of yeast and a solution containing no mold of yeast. The former is returned to the fermentation tank. The concentration of the mold of yeast activated in the process of fermentation of yeast can be kept extremely high continuously, the formation of flavor component is promoted,  and a seasoning solution having extremely improved flavor is prepared in a short time  efficiently.

Abstract: PROBLEM TO BE SOLVED: To obtain a printer having a function for index displaying an input image in which efficiency of print reserve/release operation using an index display screen is enhanced. SOLUTION: The CPU 101 in a printer 11 has control modes for reserving print, i.e., a normal mode designating in units of frame and a continuous designation mode for designating a plurality of frames collectively. These control modes are switched automatically depending on the difference of reserve/release key operation and a switching is made from normal mode to continuous designation mode when the reserve/release key is 'depressed for a long time'. In the continuous designation mode, an image designated by a cursor and subsequent images among index displayed images are entirely reserved for printing. If the image designated by a cursor has been reserved already, print reservation of that image and subsequent images are released entirely.
