Title: Improvements in or relating to the brewing of beer
IPC: C12C7/26
Filed: 1943-03-31
Abstract: 570,573. Fluid-pressure servomotorcontrol systems; valves. OLIVER, J. H. March 31, 1943, No. 5182. [Class 135] [Also in Group VI] In a brewing process in which the cooling stage is at a higher level than the boiling stage, the wort is lifted from the boiling stage to the cooling stage, by means of sterilized compressed air. For pressure vessels, either the existing hop-back or secondary vessels below the hop-back may be used, the valves being operated by hand, by electrically - operated mechanical valves of known type, or, alternatively, they may be controlled by the compressed air supply in conjunction with a float in the pressure vessel. Compressed air enters through valve 14, Fig. 3, and forces up piston 12, thus closing wort valve 10 and sealing off the pressure vessel. When piston 12 has risen above outlet 16, compressed air is forced into the pressure vessel and the wort begins to lift. Spring 17 re-opens the wort valve when the supply of compressed air is cut off, residual air below piston 12 escaping through bleed 30. Fig. 4 shows the position of the valve-operating mechanism when the air valve, Fig. 4a, is shut and the pressure vessel has started to fill. As float 27 rises, spring-loaded bracket 29 rotates disc 20 to which is fitted a pin 24 and a weight 21. When the disc has been rotated through 90 degrees, a pin 24 just engages on the vertical arm of the arm 25 and with a small further rotation weight 21 falls by gravity on to stop 23, Fig. 6, causing the valve 14 to rotate through 90 degrees to the position shown in Fig. 6a. As float 27 drops, spring-loaded bracket 28 engages lifting and rotating weight 21 till it again falls by gravity, restoring the position of Figs. 4 and 4a (Figs. 4a and 6a are viewed from behind).

Abstract: 641,164. Radiolocation. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 25, 1947, No. 5471. Convention date, Feb. 27, 1946. [Class 40 (vii)] A pulse-echo system for the permanent plotting of the distance and direction of remote objects includes a continuous conductor 12 rotated relative to a recording medium 18 in accordance with the direction of antenna 3, echoes from receiver 2 being applied to the conductor as positive pulses, and negative pulses synchronized with the transmitted pulses being applied from transmitter 1 to one end 13 of a terminated transmission line 14 so as to influence each in turn of a series of annular members 19 located beneath medium 18 and concentric with shaft 20. The medium consists of electro-sensitive paper, the voltage stress due to a positive or negative pulse alone being of insufficient amplitude to mark the paper. A mark occurs at a point corresponding to the position of the particular member 19 which has a negative pulse at the time of application of a positive pulse to member 12. This mark is displaced from shaft 20 by a distance corresponding to the time delay between transmitted and received pulses and hence to the distance between antenna 3 and a remote object. Rotation of conductor 12 results in a map-like record of all objects surrounding the antenna.
