Patent GB-2185309-A (GB)
Title: Gas bubble detector
Inventor: GREENWOOD SIMON
IPC: G01N21/35
Filed: 1986-01-14
Abstract: In order to detect the presence of gas bubbles, for example as the first sign of exhaustion of a tank of beer, an infrared source e.g. an LED and an infrared sensitive detector e.g. a phototransistor face each other at opposing sides of a body of liquid with a lens positioned in the path therebetween so as to focus infrared light towards the detector. The focussing effect of the lens is either enhanced or diminished by the proximity of the bubble and this correspondingly affects the signal from the detector which can be used, for example, to shut off the further supply of beer. Two source/detector pairs may be employed spaced at 90 DEG  around a tube through which the beer flows. The lenses maybe arranged around the internal circumference of the tube.

Patent GB-2197341-A (GB)
Title: Brewing beer
Inventor: QUAIN DAVID EDWIN
IPC: C12C11/00
Filed: 1987-09-18
Abstract: When brewers' yeast is treated with oxygen, the rate at which it takes up oxygen increases until a maximum take-up rate is reached. The yeast is then fully oxygenated. In a method of fermenting wort for the production of beer, wort that contains little or no oxygen is pitched with fully oxygenated yeast to enable fermentation to occur. The process leads to improved consistency as the outcome of the fermentation can be accurately predicted in advance. In one method, an aqueous suspension of yeast from a tank (4) is circulated by means of a pump (8) through ducting (7) containing an oxygenation cell (9). The oxygen content of the suspension is monitored by an oxygen electrode (14). A control unit (12) increases the rate at which oxygen is supplied to the oxygenation cell in such a manner as to maintain the concentration of oxygen in the suspension constant. When a steady state is reached the fully oxygenated yeast is transferred to a storage tank (17). When the yeast is to be transferred to a fermentation vessel (19) the concentration of fully-oxygenated yeast in a sample of given volume is measured by determining the rate of oxygen take-up. <IMAGE>
