Title: Digital frequency comparator circuit
IPC: G01R23/10
Filed: 1975-02-25
Abstract: 1496743 Frequency comparators HITACHI Ltd 25 Feb 1975 [1 March 1974] 7856/75 Heading H3P [Also in Division F2] A digital frequency comparator comprises two counters 1, 2, connected to receive input frequencies f 1 , f 2  and having outputs connected with a circuit 11, e.g. a bi-stable circuit, operated by an output signal from one of the two counters, wherein both counters are cleared in response to an output signal from the counter which later issues an output signal. In operation, if counter 1 produces an output first, then bi-stable 11 is triggered via AND gate 8 to produce an output at S. A signal fed back to OR gate 3 inhibits further counting by 1. Subsequently when an output is produced by counter 2, both counters are cleared via an AND gate 5. The S output of bi-stable 11 is held as AND gate 9 is inhibited by the high output of 1 sustained until the counters are cleared. In Fig. 4 (not shown), the bi-stable may be a J-K flip-flop clocked by the clear signal to pass the signals at its J, K inputs.

Title: Method of producing alcoholic beverages
IPC: C12C12/00
Filed: 1964-02-28
Abstract: In the production of an alcoholic beverage, a mash prepared from cereal grain and plant protein is subjected to decomposition and saccharification by addition of a proteolytic enzyme and a mould culture capable of saccharifying starch or one or more enzymes obtained by purifying the mould culture, and optionally some malt, and a wort prepared from the solution thus obtained is fermented and filtered to obtain the alcoholic beverage. A modification of the process involves preparing a mash from plant protein and water and adding to the mash an amount of proteolytic enzyme to effect decomposition of the protein; preparing a second mash from cereal grain with water, boiling the mash, cooling to a temperature of about 55 DEG -85 DEG C., adding a mould culture capable of saccharifying starch or an extract of such a mould culture containing enzymes, to the mash and subjecting it to saccharification for about 3 hours; combining the two separate mashes obtained, and hopping, boiling and filtering the mixture to obtain a clear hopped wort, which is fermented and subsequently filtered and carbonated to obtain the alcoholic beverage.  The beverage product is packaged and subjected to preserving processes.  According to an example, 27.5 parts by weight of gluten are added to 200 parts by volume of water.  This mash is heated to 50 DEG C. and decomposed by the addition of 0.28 parts by weight of proteolytic enzyme, and maintained at the same temperature for one hour.  Separately, 33.4 parts by weight of rice are added to 1,000 parts by volume of water and subjected to boiling with stirring.  After boiling, the rice mash is cooled to 55 DEG -85 DEG C. and 10 parts by weight of powdered malt and 60 parts by weight of rice koji are added.  The rice koji is prepared by cultivating Rhizopus delemar, Aspergillus oryzae Aspergillus flavus or Aspergillus niger on rice media of specified composition.  The saccharification is carried out at 55 DEG -85 DEG C. for 3 hours. The mashes are then mixed and boiled for 1.5 hours with 1.7 parts by weight of hops.  Hopped, cooled wort is separated from solid matter by filtration and subjected to fermentation by the addition of 100 parts by volume of yeast culture of the bottom-fermenting type.  The temperature is held at about 8 DEG -14 DEG C. for 10 days.  The product is then fermented at a temperature of 1 DEG -5 DEG C. in a closed fermenter for 60 days and filtered. The brewed beer is carbonated.  According to the procedure of further examples, a mixture of rice, barley and wheat replaces the gluten, and barley koji or an enzyme preparation extracted and purified by alcohol precipitation or diethylaminoethyl cellulose treatment is employed in place of the rice koji.

Title: Improvements in radio blind-landing devices for aircraft
IPC: G01S1/02
Filed: 1943-05-26
Abstract: 578,094. Wireless blind landing systems. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. May 26, 1943, No. 8450. Drawings to Specification. [Class 40 (v)] A blind landing system comprises, in one form, a transmitter on the aircraft emitting oscillations of a predetermined frequency, at least one pair of spaced receivers on the airfield, and means for measuring the phasedifference of the oscillations set up in them by the transmitter. This allows the difference in the distances of the aircraft from each of the pair of receivers to be determined by an operator on the ground and communicated by radio-telephone or otherwise to the pilot. In another form, the system comprises a pair of spaced transmitters on the ground emitting oscillations of the same predetermined frequency and of constant phase difference, which may be zero, and means on the aircraft for measuring the phase difference between the oscillations reaching it from the two transmitters. In this case, the corresponding difference in the distances to the two transmitters is determined on the aircraft. It is explained in the Specification that by making these measurements relatively to a pair of stations on a line perpendicular to the runway and equidistant from it, the pilot may learn whether he is in the vertical plane through the runway, and if not, on which side of it he lies, and to which side of it he is approaching or from which he is receding. If in addition he knows his distance from the plane in which the two stations lie, he can also determine his distance from the vertical plane through the runway and his rate of approach to or recession from it. Further, similar measurements relative to two stations on the line of the runway, one outside the airfield at the approach end and the other within it, allow a close estimate of the distance from the touchdown point to be made. The oscillations on which the phase-difference measurements are made are preferably modulations of a radiofrequency carrier. A desired curved course may be maintained by imposing, in the first form of the invention, a constant relative phase shift to the oscillations received from the transmitter at the two receivers, and in the second form by maintaining a constant phase difference between the oscillations emitted by the two transmitters, the aircraft being in each case held on a course such that the compared oscillations are in phase. Specification 452,235 is referred to.
