Title: Improvements in and relating to hops
Inventor: BISHOP LAURENCE ROBERT
IPC: C12C3/08
Filed: 1969-01-09
Abstract: 1,236,731. Hop extracts. WATNEY COMBE REID & CO. Ltd. 7 Jan., 1970 [9 Jan., 1969], No. 1393/69. Heading C2C. [Also in Division C6] The alpha acids and beta acids are extracted from resinous hop material such as lupulin in the following process steps: (1) (optional) the hop material is given an initial wash with sodium or potassium hydrogen phosphate buffer solution of pH 4-9to extract selectively tannins and fatty acids, the temperature being kept low enough to avoid substantial dissolution of the alpha acid content of the hop fraction; (2) the alpha acids are then extracted with the aid of aqueous disodium or dipotassium hydrogen phosphate, or sodium or potassium citrate, at a pH in the range 7 to 9 and a temperature between 40‹ and 90‹ C.; and (3) the beta acids are extracted from the residue with a 0À2-2À0% by weight aqueous solution of sodium or potassium carbonate at a temperature in the range 25‹ to 100‹ C. Crystallization of the extracted alpha acids and beta acids may be promoted by the addition of acid, e.g. citric acid and gaseous carbon dioxide, respectively. The extractions may be performed by percolating alkali through a column of the lupulin-rich powder or by spraying the alkali on to the inside surface of a packed bed of the powder in a basket centrifuge. In both cases a filter aid (specified) should be included. The extracted alpha acids may be isomerized by boiling at atmospheric pressure for 2 hours at a pH of 9 (or longer at a lower pH). The extracted beta-acids may be oxidized to hulupones by gaseous oxygen at a temperature in the range 70-90‹ C.

Patent GB-771938-A (GB)
Title: Improvements relating to titanium-bearing slags
IPC: C22B34/12
Filed: 1955-01-18
Abstract: Titanium-bearing slags, produced by smelting iron-titanium ores and containing dititanates together with smaller amounts of glassy siliceous material, are improved in reactivity by annealing the slags in the temperature range between the dititanates crystallizing point and the freezing point of the glassy material for a time sufficient to convert the titanates into coarse crystals having a width greater than the average particle size diameter to which the slag is ground for digestion with strong sulphuric acid, thereby converting the originally homogeneous slag into a body of coarse dititanate crystals having the glassy material segregated at their interfaces.  Slags are annealed by casting into masses of 2-8 tons, and cooling by convection. Oxidation of compounds to rutile is prevented by surrounding the slags, during annealing with a gas devoid of free oxygen.

Title: Improvements in and relating to weighing apparatus
IPC: G01G19/22
Filed: 1947-01-16
Abstract: 641,423. Weighing-apparatus. WILFLEY MINING MACHINERY CO., Ltd., and BELLAMY, E. A. Jan. 16, 1947, No. 1508. [Class 143] A series of superposed and interconnected steelyards for weighing-out the solid ingredients and water of a mix, the ingredient steelyards having compensating steel yards adjustable to the calculated moisture content of the ingredients, has means for automatically rendering the compensating steelyards ineffective when the water steelyard is brought into operation and reapplying them when the next mix is proceeded with. The embodiment shown has three upper steelyards S 2'  S 3  and S 4  for aggregate, a steelyard S, for sand and a lowermost SW for water. The other steelyard SC shown is for cement and is entirely independent. A common container for the aggregate and sand is suspended from the uppermost, and a separate tank for water from the lowermost. The steelyards are interconnected by a vertical bar 6, pivoted at 6a to the upper steelyard and having pins 5 and 20 underlying others. Pivoted handles 15 project from an enclosing casing and have arms with rollers 14 for lifting the steelyards to disable them when the handles are depressed. The aggregate and sand steelyards have moisture compensating steelyards 2 mounted coaxially therewith and adapted to rest on pins 9 on their main steelyards to load them additionally. In operation, the main steelyard poises 8 are adjusted to the required weights of aggregate, sand and water, whilst the compensating steelyard poises 4 are set to the calculated weight of water in the aggregate and sand. The uppermost handle 15 is then raised to free the uppermost aggregate steelyard and aggregate is loaded into the container until a balance is indicated by the pointer 7. The second aggregate steelyard handle 15 is then raised to free its steelyard and further material is loadedin until the pointer 7 again indicates a balance. This is repeated for the steelyards S., and S,. Finally the water steelyard handle 15 is raised and this not only releases the water steelyard but, through a bar 22 and lever 29, lifts a bar 10 which, by means of pins 11, lifts the moisture compensating steelyards 2 off the pins 9 on their main steelyards. The weight of water then added to balance the system is consequently less than that required in the mix by the weight of water already present in the moist aggregate and sand. The handles 15 are interconnected by a pin- and-slot linkage so that the uppermost only need be depressed to disable all three steelyards at the completion of each weighing- out. Interlocking means may be provided to ensure that the handles are operated in correct sequence, and a push-button electric control is mentioned.

Abstract: 130,368. Hettinger, J., and Vandervell, C. A. Jan. 31, 1918. Locating sounds.-An optical indicator operating as the receiver of a sound-locating device consists of two or more luminous sections, the luminosity of at least one of which is varied by the received sounds. The sections are illuminated by incandescent lamps or filament, supplied with continuous current upon which is superposed a current controlled by the sound, or the luminosity is varied by causing a current of air, electro-magnetically controlled, to impinge upon the incandescent filament. Manometric names controlled directly by the sound or indirectly by means of a microphone and an electro-magnet may be employed, or the magnet may operate a shutter device in front of the incandescent lamp. The detection of a submarine is effected by placing a number of boxes M, Fig. 8, around a ship's hull and by connecting these boxes each of which contains a diaphragm M, to manometric capsules n, the flames of which are placed behind translucent screens h. The change in the luminosity of a screen serves to detect the presence of a submarine. To indicate optically the path of flight of an aeroplane over an area, the area is divided into sections each of which contains a microphone B<1>, B<2> - - B<100>. Figs. 4 and 19, the circuits of which are inductively coupled to a series of low voltage lamps e<1>, e<2> - - e<100>, Figs. 4a and 19. The lamps e<1>, e<2> - - c'oo are supplied with current from a battery G and upon the operation of a microphone, due to the sound emitted by the aeroplane, an alternating current is superposed upon the current from the battery G to increase the luminosity of the lamp associated with the operated microphone. The lamps e<1>, e<2> - - e<100> are placed over a map c of the area, and the projection b, Fig. 4, of the trajectory of the aeroplane is produced as a line b<1>, Fig. 4<a>, on the map. To ascertain whether increased luminosity of a lamp is due to an aeroplane or to the sounds produced by trains and the like, a telephone receiver N is provided, adapted to be inserted in parallel with the lamps by means of a switch P. The microphone may be suspended from a captive balloon and the arrangement used for determining the altitude of an aeroplane in addition to its position in an area. In the modification shown in Fig. 20, the locating station is provided with nine illuminated sections, the middle one 5 of which is divided into eight subsections, so that, when the aeroplane is over a particular subsection of the section 5, this section will be more strongly illuminated than the other sections, and the section nearest the subsection under consideration will be more strongly illuminated than the others.
