Title: Improvements in or relating to the brewing of beer
Inventor: COUTTS MORTON WILLIAM
IPC: C12C11/00
Filed: 1963-12-09
Abstract: In manufacturing beer, ale, porter and stout in a continuous fermentation system, wort from a brewhouse is transferred in batches to a series of vessels wherein the wort is mixed with a predetermined quantity of yeast-containing fermenting wort from a continuous fermentation plant and the resulting mixture is continuously transferred to the continuous fermentation plant. In a preferred procedure, unfermented wort at a temperature of between 50 DEG F. and 140 DEG F. is added in batches at intervals of between 1 and 12 hours to fermenting wort containing yeast in suspension and oxygenated by injection of air, the ratios of unfermented wort to fermenting wort ranging between 12:1 to 1:12, but preferably as 1:1.  The two operational examples disclosed are based respectively on the following procedures.  (1) A quantity of fermenting wort, containing yeast in suspension, from a continuous fermentation system is caused to flow substantially continuously to an accumulating vessel. When a batch of wort from the brewhouse is ready to be transferred to the fermentation system, it is caused to flow in to a second vessel. While the batch of wort from the brewhouse is being added to this second vessel, the accumulated fermenting wort in the accumulating vessel is rapidly transferred to the second vessel.  The mixture is allowed to remain in the second vessel until the next batch of wort is ready to be conveyed from the brewhouse.  At this stage, the contents of the second vessel are rapidly removed to a third vessel, the outflow of which runs continuously to the inlet of the continuous fermenting system.  (2) Fermenting wort from a continuous fermentation system flows continuously to one or another of two vessels of a continuous fermentation wort supply system alternatively, at a desired flow rate.  In these vessels the fermenting wort mixes with unfermented wort, a batch from the brewhouse going to that vessel to which, at that particular time, the fermenting wort from the continuous fermentation system is flowing. When either of these vessels has the required volume of unfermented wort and fermenting wort mixture, this mixture is pumped at a constant rate to a third vessel.  This third vessel is kept at a constant volume and the outflow flows continuously to the inlet of the continuous fermentation system.  It is stated that the unfermented wort is thereby reduced in pH and, by oxygenating the fermenting wort before the unfermented wort is mixed with it, the finer flavour producing products of the unfermented wort are maintained free of oxidation.

Abstract: 1513810 Transistor amplifier; loudspeaker circuits SONY CORP 5 Dec 1975 [11 Dec 1974] 50064/75 Headings H3T and H4J [Also in Division H2] In a transistor amplifier comprising bipolar transistor 14 feeding via output stage FET 15 a load 7 such as a loudspeaker, the whole being fed with a signal via an input stage, not shown, to input terminal t 1 , a protective circuit 21 detects conditions which overload the amplifier and applies a signal to a muting circuit comprising a switching element such as transistor 16 which causes both transistor 14 and FET 15 to cease to conduct. The A.C. output voltage across load 7 is rectified by diode 8 and the A.C. load current, indicated by the volt drop across shunt 6 is rectified by opposite poled diode 11, as seen in the equivalent circuit of Fig. 5, the nett voltage on capacitor 12 being related to the peak current and voltage (not necessarily in phase) and the forward drops of the two diodes. Transistor 13 becomes conducting and sends a signal indicating overload when the load impedance Z and peak current i p  in Fig. 6 or peak current and voltage i p , e p  in Fig. 7 fall in their respective shaded areas, as with a short circuited load. In the absence of overload transistor 16 remains cut off, particularly if its emitter is taken to a tapping on resistor 20. Components 17, 18, 19 ensure that transistor 16 mutes on overload both transistor 14 and FET 15. The FET may preferably have triode characteristics (Figs. 1-3, not shown) but may be pentode-like, of junction or MOS type. In the muting circuit transistor 16 may be replaced by another semiconductor switching device. In a second embodiment (Fig. 8, not shown) two complementary FET's in series, each driven by its own bipolar transistor, supply the load in class AB push pull, these amplifying stages being fed by an input preamplifier based on two differential stages. Two identical complementary detectors and muting circuits are included, although one detector circuit can serve for both.
