Title: The dispensing of beer and other beverages
Inventor: LITTLE WILLIAM
IPC: G01F11/06
Filed: 1989-03-23
Abstract: Strong beer, that is beer of a strength greater than that of beer to be dispensed, is either brewed strong or made by removing water from brewed beer, and is mixed with carbonated water on site so as to make beer suitable for consumption. Beer transportation costs are thus reduced. Mixing is carried out as the beer is required, and the relative quantities of strong beer and carbonated water are determined by metering means. The metering means may comprise a volumetric meter for one liquid and a volumetric meter for the other liquid. Alternatively a volumetric meter for one liquid may discharge into another such meter which is then topped up with the other liquid. Another type of metering means comprises two pistons (35, 36) disposed in a single cylinder (30) and travelling between end closures (31, 32) of the cylinder and an intermediate drum (27). The individual volumes swept out by the pistons can be adjusted by shifting the cylinder and closures relative to the drum, the total volume remaining unaltered. This kind of metering means can be used for mixing any beverage liquids in predetermined proportions. Beer from (41) passes via pump (45) to fob detector (46) and line (51) to the meter. Water from (59) is filtered at (60), pumped (62) to carponator (63) and passes via fob detector (65) and line (67) to the meter; control unit (50) commands the inlet and outlet valves. <IMAGE>

A resist film having an opening in a selected location is formed on the second semiconductor layer. Using this resist film as a mask, the semiconductor layers are selectively etched. The gate electrode is formed in the recess 20 created by the etching. Instead of two or more semiconductor layers, a single semiconductor layer having a composition which varies across its thickness may be used. The FET may be a MESFET or a HEMT. <IMAGE>

Patent GB-918584-A (GB)
Abstract: 918,584. Measuring rotor unbalance electrically. AVERY Ltd., W. & T, May 13, 1959 [May 16, 1958], No. 16363/59. Class 40 (1). [Also in Group XIX] To measure the static unbalance of a rotor 1 (Fig. 1) it is mounted on a shaft 2 supported by leaf springs 4 so that it can oscillate in the directions indicated by the arrow A when a motor 5 is energized and drives unbalanced discs 5a, 5b. The unbalance in rotor 1 produces a torque on shaft 2 which is zero when the position of the unbalance mass and shaft 2 are in line with arrow A, and is a maximum at 90 degrees from this position, the twist on shaft 2 being indicated by transducer 9 whose casing is attached to an inertia mass 8 and whose movable element is attached via rod 10 to the shaft 2. The shaft 2 and rotor 1 are slowly rotated until the output from transducer 9 is zero, giving the angular location of the unbalance, and then rotated through a further 90 degrees when the transducer output indicates the magnitude of the unbalance, which may be calibrated by using a known unbalance mass 12 located at 90 degrees to the existing unbalance, or by comparison with the output from a reference generator 7 driven by motor 5. In another embodiment (Fig. 2), the test rotor 21 is vibrated by an oscillating motor 27 about an adjustable axis X-X determined by the position of a bearing block 26, the unbalance in the rotor 21 producing a rotation of the shaft 22 in accordance with the angular position and magnitude of the unbalance. Thus, with the axis X-X passing through the centre of mass 21a of rotor 21, as shown, the measured unbalance is that of the other part 21b of rotor 21, and by moving the bearing block 26 along so that the axis X-X passes through the centre of mass 21b, the measured unbalance becomes that of mass 21a. The invention may be applied to measuring the unbalance of the moving part of a moving coil meter, the moving coil 54 (Fig. 5), acting as its own transducer, being connected to a further meter 56, and to measuring the unbalance of the balance wheel of a watch, using a proximity type pick-up.
