Title: A process and apparatus for the continuous brewing of beer
IPC: C12C7/00
Filed: 1960-05-04
Abstract: In a process and apparatus for the continuous brewing of beer, ground malt and water at a desired temperature are fed, by a conveyer 3, into a mashing vessel 8 and mashed therein with heated water and/or steam supplied through perforated pipes 16.  The resulting mash, from which some wort has been drawn off as described below, is then passed through a valve 17 and a conveyer 18 into a second mashing vessel 22, provided with a perforated pipe 28 through which heated sparging water and/or steam may be supplied. Spent malt is discharged through a valve 39 and a helical conveyer 40. Wort is drawn from the vessels 8 and 22, respectively, through conical perforated screens 10 and 33, pumps 12 and 35 and pipes 13, 36 and 46 into a heat-insulated, e.g. heated storage vessel 47 or 48, or into both. The wort is then passed, and blended as desired, through a system of pipes and valves into a heated copper 50 or 51, or into both, and boiled therein with hops introduced through a rotary valve 61.  The boiled wort is fed into a hopback 68, or a plurality thereof, provided with a perforated screen 69, through which the wort passes into a pipe 72 and is then pumped, through a pipe 74 and a heat-exchange cooler 75, into a tank 78.  The spent hops retained by the screen in the hopback are sparged with hot water and/or steam and discharged by a helical conveyer 71. The cooled wort is fed, by a pump 80, through an air and/or carbon dioxide aerator 81, into fermentation apparatus in which it is subjected to "top" fermentation with added yeast in successive vessels 86, 87, 88, where floating excess yeast is removed, and 89, from which beer of relatively high specific gravity is drawn off. The cooled wort may also be fed, by the pump 80, through an air and/or carbon dioxide aerator 84, into fermentation apparatus in which it is subjected to "bottom" fermentation with added yeast in successive <PICT:0943091/C3/1> vessels 115, 116, 117, where excess yeast deposited is removed, and 118, from which beer of relatively low specific gravity is drawn off for filtration and lagering.  Oxygen or sterilized air may be fed into the fermenting beer. <PICT:0943091/C3/2>

Title: Improvements in and relating to the recovery and refining of sulphur
IPC: C01B17/027
Filed: 1922-06-12
Abstract: 205,141. Robinson, C. S. June 12, 1922. Sulphur. - To obtain sulphur free from the impurities which prevent satisfactory combustion, the sulphur is volatilized from materials containing it in the free state, the necessary heat being provided by the combustion of the minimum proportion of the sulphur. Preferably the sulphur-containing material is maintained in continuous motion counter-current to the gas for effecting combustion. In an example, the crude sulphur is fed by the device 1 into a chamber 2, provided with shelves 3 over which it travels in counter-current to an air-supply entering by an opening 7 from the flues 4 within the walls of the chamber. The volatilized sulphur passes by way of a passage 9 to a condensing chamber 8 also airjacketed and fitted with a condenser 15. By passage through the jackets the air-supply is preheated. Molten sulphur is tapped off bv a pipe 14. If the plant is associated with a sulphuric acid plant, the jackets may be omitted. Instead of the above described apparatus, ordinary sulphur burners, such as the Herreshoff or Wedge furnaces, may be employed, but in all cases a condenser must be fitted.

Abstract: 1349260 Cryogenic containers HITACHI SHIPBUILDING & ENG CO Ltd 21 May 1971 [22 May 1970 (2)] 16314/71 Heading F4P [Also in Division F2] A cryogenic container comprises a plurality of cylinder assemblies 9a, 9b, 9c, 9d located between the tank bottom 3 and the floor 5 of a supporting structure such as a ship. Each assembly 9a comprises two cylinders 14, 15 arranged on either side of a chock 20 supported by the tank bottom 3. Cylinders 14, 15 are mounted on the hold floor 5. Pistons 12, 13 are reciprocable in cylinder 14, 15 and their free ends engage opposite sides of chock 20. The outer chambers 21a, 22a of cylinders 14, 15 are interconnected by a line 25 having a throttle valve and the inner chambers 21b, 22b by a line 26 with a throttle valve 24. If expansion of the tank takes place and chock 20 moves away from the vertical tank axis O, chamber 21a is pressurized and fluid will pass to chamber 22a which thus moves piston 13 to follow chock 20. During a contraction of the tank, chamber 22a is initially pressurized and a similar process ensues. Thus expansion and contraction of the container can take place since they occur so slowly that the throttled passages 25, 26 can accommodate the movement of oil between the chambers that is required. However, if a rapid movement of the supporting structure occurs, such as the pitching and rolling of a ship, then the throttled passages reduce movement of the tank to a negligible amount. Further modifications, in which expansion and contraction can take place but in which no bulk movement whatsoever of the tank can take place are illustrated in Figs. 6 and 7 (not shown). Rotation of the tank can also be prevented (Figs. 8, 9, and 10, not shown).
