Title: Continuous method and apparatus for making liquid hop extract
IPC: C12C3/08
Filed: 1965-03-18
Abstract: A continuous method of making a liquid hop extract involves the steps of continuously circulating a liquid solvent for hop extractives, e.g. water. through a hop boiling vessel, continuously passing hops through the hop boiling vessel in the same direction as and in contact with the liquid solvent, the hops being passed through the hop boiling vessel under positive impetus whereby they pass through the hop boiling vessel in a pre-determined time, boiling the hops and liquid solvent in the hop boiling vessel to dissolve hop extractives into the liquid, separating the hops from the liquid after the circulation through the hop boiling vessel to yield a liquid hop extract and spent hops and taking a porof the liquid hop extract to beer processing, and the liquid solvent that is continuously circulated through the hop boiling vessel comprises (i) fresh solvent to replace the liquid extract passed to processing and liquid losses, and (ii) the liquid hop extract not passed to the processing.  Hops and solvent admitted to a boiling vessel 10 through a line 12 progress to the outlet 14 under the impetus of a rotating closely-aligned screw conveyer 20 and are boiled by heat supplied over at least part of their path by heaters 52.  Liquid hop extract and spent hops from the boiler are pumped by a pump 24 on to an endless screen 28 from which the liquid hop extract is collected in a reservoir.  The spent hops are sparged with fresh solvent from sprays 36 and finally are pressed by a roller 41 before being discharged off the screen.  Both the sparge water from reservoir 38 and part of the liquid hop extract are recirculated to the boiling vessel 10.  A further part of the liquid hop extract may be recirculated through a line 48 in order to reduce the proportion of hops-to-liquid handled by the pump 24. In the boiling vessel proportions of above 2 lbs hops to 31 United States gallons of water are preferably maintained. <PICT:1044849/C6-C7/1>

Abstract: 775,156. Heating steam boilers by hot liquids or gases. BABCOCK & WILCOX CO. April 21, 1955 [May 6, 1954], No. 11566/55. Class 123(2) A boiler wherein steam is generated by indirect exchange of heat between water and a heat transfer fluid at a high temperature and pressure and which may be of a corrosive nature consists of a steam and water drum 10 and a U-shaped heat exchanger 14 arranged symmetrically below the drum and connected thereto by uniformly spaced riser tubes 16 and downcomer tubes 18, the tubes being bent as shown in Fig. 2 to provide sufficient flexibility to enable them to take up the differential expansion of the drum and heat exchanger which are separately supported. The heat exchanger 14 comprises an outer shell 42 of circular cross section and of U-shape having parallel legs 43, 45 connected by a bight section 47. To the ends of the respective legs 43, 45 are welded thick tube plates 44, 46 and hemispherical pressure heads 48, 52 which together form heat transfer fluid inlet and outlet chambers 50, 54. Disposed within the shell 42 is a bundle of U-tubes 60 opposite ends of which are welded into the tube plates 44, 46 to provide a flow path for the fluid between the chambers 50, 54. The tubes are supported in each leg 43, 45 of the shell by plates 70 perforated with slightly oversize holes in which the tubes can move horizontally. In the bight section 47 the tubes rest on bars which extend horizontally across the section and are supported by a ring 75. The tubes are thus free to move horizontally within the shell whilst being restrained in a vertical direction. The shell, tube plates and pressure heads are made of high tensile carbon steel. When corrosive heat transfer fluid is to be used, the interior surfaces of the chambers 50, 54 are clad with stainless steel and the U-tubes 60 are made of this material.

Title: Improvements in or relating to hydraulic fluid friction brakes for motor road vehicles
Inventor: SPURRIER HENRY
IPC: B60T1/10
Filed: 1953-04-27
Abstract: 742,293. Hydraulic fluid-friction brakes. LEYLAND MOTORS, Ltd. July 16, 1954 [April 27, 1953], No. 11620/53. Class 103 (1). [Also in Groups XIII and XXXI] In a supplementary braking system for a motor vehicle, a liquid brake is provided adapted to dissipate energy by fluid friction and comprises an annular chamber 8 fitted with fixed blades 9 and within which a bladed wheel 7 is adapted to rotate with the engine shaft 5 through a flexible shaft 6. The unit is designed to pump liquid, e.g. water, from an inlet 11 in the middle to an outlet 12 at the periphery and through an external circuit which connects the outlet with the inlet 11. This external circuit includes a radiator 2; the liquid brake drawing water from the bottom tank 13 and returning it to the header tank 14 of the radiator. The flow of water is controlled by two valves mounted upon a common stem 15 and operated by an arm 22 which may be connected to a separate driver's handle or coupled with the brake pedal, or with the accelerator pedal so that the liquid brake comes into action whenever the fuel supply is shut down. In the position illustrated, the outlet is freely open through a passage 16 while the inlet 11 is connected by a groove 17 and a port 18 to atmosphere so that the annular chamber 8 is emptied of water and no fluid friction braking takes place. When the arm 22 is turned through 90 degrees the narrow passage 19 is aligned with the outlet and the wide passage 21 with the inlet filling the annular chamber 8 with water and kinetic energy of the vehicle is dissipated by the fluid friction thus heating the water. Sufficient flow occurs from the annular chamber 8 through the narrow passage 19 to the header tank 14 to keep the temperature rise below boiling point.

Abstract: 869,574. Drying apparatus. SULZER FRERES S. A. April 15, 1958 [April 18, 1957], No. 12007/58. Class 34(2) Coal from a line 3, Fig. 1, is dried before entering a pulverizer 4 by being fed to the latter through a shaft by temperature controlled flue gases conducted through a duct 2 from a steam generator 1. The control is effected by bleeding off vapour from above the sifter 6 and storage bin 7. to which the pulverized coal is carried, and passing it by a fan 11 to the flue gases through a pipe 13 after purification in a fine filter 12. The main vapour flow is passed to the atmosphere by a fan 9 after passage through a filter 8. Some vapour may pass to the dried coal at the pulverizer through a line 15 in dependence upon the temperature of the mixed gas and vapour in the duct 2. The speed of fan 9 depends upon the temperature of the vapour before the sifter. In a modified plant only the filter 8, Fig. 2, is employed and the vapour feed through a line 20 depends upon the temperature of the mixture whilst the vapour flow to atmosphere depends upon its pressure. In yet another plant only one fan 9, Fig. 3, and one filter 8, are used, the fan speed depending upon the vapour pressure before the filter. The vapour supply to the dried coal through the line 15 depends upon a flow meter fitted in the line whilst the vapour discharge to atmosphere is dependent upon the vapour temperature before the sifter. In a modified one fan, one filter plant, vapour may pass to the dried coal through parallel lines 15, 25, Fig. 4, the amounts passing depending upon the flow in the lines, the flow in line 10 and the flow prior to the sifter.
