Patent GB-1109311-A (GB)
Title: Improvements in or relating to the production of grain whisky
Inventor: LAWRIE JAMES WADDELL
IPC: C12H6/02
Filed: 1963-08-07
Abstract: <PICT:1109311/C6-C7/1> Grain solids are recovered from spent liquor from the production of grain whisky by reducing the suspended-solids content of the spent liquor (as by centrifuging it) and concentrating the solids-reduced spent liquor by evaporation.  The suspended-solids content of the spent liquor should be reduced to not more than 0.5% by weight and this may be achieved indirectly by passing unfiltered mash through a multi-stage rotary vacuum filter to remove suspended grain solids and draff. The operational steps are diagrammatically depicted in the figure.  Up to 30% of the input to the fermenter can consist of solids-reduced spent wash from the distillation column. The evaporator 6 may consist of multi-stage tube-type and plate-type evaporators.  The highly concentrated syrup, of up to 60% solids content, obtained by the evaporation may be dried to produce distillers' dried solubles or mixed with the draff and grain solids and then dried to produce distillers' dark grains.

Title: Control arrangement for a bulit-up-symbol printer
IPC: B41J23/36
Filed: 1972-07-06
Abstract: 1393168 Control of printers ITT CREED Ltd 6 July 1972 31672/72 Heading G4H A control arrangement for a built-up symbol printer having a linear array of symbol-part printing members comprises circuits A-N each individually controlling one of the printing members by means of a respective armature, circuits B-N being capable of energizing the associated armature in either of two polarities while circuit A energizes its armature in only one polarity, each circuit including gates 5, 6, 9, 10 propagating signals in a downstream direction from A to N, the arrangement being such that each circuit energizing its armature does so in a polarity different from that of the nearest energized upstream armature and each circuit not energizing its armature passes downstream unchanged polarity information from the nearest energizing upstream circuit. To print a particular symbol, the appropriate ones of leads 1a-1n receive "1" inputs. At the end of the array, A can only be "positively" energized ("1'' on lead 1a); in this case lines 7, 8 carry 0, 1 signals to B. If 1b has a "1" input, then B is "negatively" polarized by a "0" output at NAND gate 4b, gates 5b-10b feeding 1, 0 signals to lines 7, 8 (indicating B's negative polarity). If 1b has a "0" input (B not selected), then neither 3b nor 4b is activated and lines 7, 8 carry 0, 1 signals (positive polarization of A). This process extends along the array by means of the signals on lines 7, 8 until all the selected armatures have been energized.

Filed: 1974-07-17
Abstract: 1480287 Ultrasonic inspection KRAUTKRAMER GmbH 17 July 1974 [7 Sept 1973] 31703/74 Heading G1G To provide a focused transmitting or receiving beam, ultrasonic transducers in an array are activated in groups, and different groups are activated sequentially to cause a focus point to scan a test specimen, each group comprising a plurality of sub-groups spaced by transducers lying between them.  In the Fig. 4 embodiment, groups 32, 33a, 33b, 34a, 34b of transducer elements in linear array 28 are used together for transmitting to, or receiving from, focal point 29. The distribution of the groups is analogous to the zone spacing of a Fresnel zone plate. The intermediate groups of elements are either inactive, or their signals are used with phase-inversion. By use of a shift register the distribution is shifted one element spacing at a time along array 28 to provide lateral scanning of point 29. The principle can be extended to give scanning in two dimensions by use of orthogonal arrays of transducer elements Fig. 7 (not shown), or by use of sequentiallyactive parallel strip-form transducers which provide scanning in the second dimension Fig. 6 (not shown).

Title: Improvements in or relating to automatic frequency control systems
IPC: H03L7/16
Filed: 1949-12-12
Abstract: 669,688. Automatic frequency control systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Dec. 12, 1949 [Dec. 17, 1948], No. 31825/49. Class 38 (iv). The output frequencies of an oscillator capable of operating at either of two related frequencies (or the outputs of two oscillators operating at unrelated frequencies), are stabilized by generating a first stable frequency of value equal to half the sum of the two oscillator frequencies, which when mixed with either of the two oscillator frequencies produces a resultant control frequency which is normally the same as the second stable frequency and equal to half the difference between the two oscillator frequencies. Any difference between the control frequency and the second stable frequency is used to correct the oscillator. The oscillator 10b, Fig. 3, has outputs of frequencies f and nf. A first stable frequency equal to (nf+f)/2 is obtained from a multiplier 12b, which multiplies (n+1)(n-2)/2 times the output of a crystal controlled oscillator 11b having an output of the second stable frequency (equal to half the difference between frequencies f and nf). The output of the multiplier and either output of the oscillator 10b are applied to a mixer 13b to produce control oscillations normally having a frequency of (nf - f)/2. This is compared with the frequency of the stable oscillator 11b in a zero beat automatic frequency control circuit 14b, and any error causes a correcting voltage to be applied to the oscillator 10b. Since an increase in the frequency f results in a decrease of the frequency obtained from the mixer 13b whilst an increase in the frequency nf results in the opposite, a polarity reversing switch 16 in the feed from the A.F.C. circuit to the oscillator is ganged to the frequency change-over switch S. In a modification, Fig. 4 (not shown), frequencies of (n + 1)f and n - 1)f are similarly stabilized against an oscillator operating the second stable frequency f multiplied n times to produce the first stable frequency nf. In a further modification, Fig. 5 (not shown), the outputs of two separate oscillators having outputs of frequencies nf and mf (where m # n )are stabilized by selectively applying the outputs to a mixer to which is also supplied oscillations of the first stable frequency (mf+nf)/2, obtained by generating the second stable frequency (mf-nf) /2 and multiplying it (m+n (m - n) times. In a further modification, Fig. 6, two separate oscillators 10e, 10ee having outputs of unrelated frequencies f and F are stabilized by selectively applying these outputs to a mixer 13e to which is also applied oscillations at the first stable frequency (f+F)/2 obtained directly from a stable oscillator 11e. A second oscillator 11ee provides the second stable frequency ( f - F)/2 and this is used as the reference source for the comparator 14e from which control signals are derived as before. U.S.A. Specifications 2,274,434 and 2,288,025 are referred to.
Patent GB-318256-A (GB)
