Title: Process for the preservation of the juices of fruits, vegetables and the like
IPC: A23L2/48
Filed: 1938-04-22
Abstract: 508,333. Preserving fruit, vegetable, and like juices. TRZOSKA, F. April 22, 1938, No. 12094. Convention date, April 23, 1937. [Classes 14 (ii) and 49] Fruit, vegetable, and like juices are preserved by multi-stage treatment with alternating or polyphase electric currents, a large body e.g. 3,000-20,000 litres, being heated slowly to about 50‹ C., the deposits which collect at the bottom and the lighter albuminous material which rises to the top of the liquid being drawn off separately after which the clarified juice is drawn off into smaller containers of about 30-50 litres capacity and heated therein by the current very quickly to a temperature up to 68‹ C. and is then drawn off in a sterile condition. The preliminary treatment may be carried out in two or more stages. Dilution, mixture, sweetening, &c. of the liquid, e.g. addition of water and sugar, honey &c. to rhubarb, currant and other acid juices is carried out prior to the final stage. The juices are kept as far as possible out of contact with metal during crushing of the fruits, filtering and storage, the containers and ducts used being preferably made of wood, porcelain, glass, earthenware, stoneware, hard rubber, &c., or of metal having a suitable coating of vitreous enamel, synthetic resin, &c. The juices are kept out of contact with air during the treatment by using closed vessels and keeping them filled with.liquid. The electrodes used may be of metals such as platinum, osmium, tungsten or molybdenum, or metalloids such as graphite, and may be disposed near the bottoms of the treatment vessels. During the treatment in the smaller vessels filtered air may be driven by sharp impulses through the liquid to ensure mixing and uniform treatment. The treated juice may be drawn off into bottles &c. which are completely filled and immediately sealed before the liquid cools. With grape juice, after the preliminary treatment the juice may be kept for some weeks or months, the treatment being if necessary repeated, prior to carrying out the final stages.

Title: Dosimeter for evaluating the dosage of penetrating radiation
IPC: G01T1/08
Filed: 1956-04-20
Abstract: 796,239. Radiation dosimeters. GENERAL ANILINE & FILM CORPORATION. April 20, 1956 [May 17, 1955], No. 12153/56. Class 98(1) A dosimeter for penetrating radiation consists of a closed casing of material transparent to gamma-rays and having a recess wherein a fluorescent screen, a step wedge, and a light-sensitive element bearing a high-speed print-out emulsion facing the wedge are disposed in contact with one another, and means for viewing the emulsion of the light-sensitive element. As shown, a casing 1 is formed with recesses 2, 3. A fluorescent screen 5 is located in recess 2, with .a step-wedge 6 resting against it. The wedge 6 has five steps, each bearing a row of markers. The light-sensitive printout emulsion, which is of the kind described in Specification 795,042, is carried on four strips 8, next to the step-wedge 6, each strip having a leader strip 11. A back plate 12 closes the casing 1 and holds the various parts in position. In use, when radiation activates screen 5, the ultra-violet fluorescent light passes through the wedge 6 to the strips 8. The strips are pulled up by the leaders, one at a time, for viewing through an orange window 14. If no images are visible, the strips may be exposed through window .14 to a bright light. After a time, if the dosimeter has received gamma-radiation, one or more images of the marks on the step-wedge appear. Continuing exposure slowly fogs the remainder of the printout emulsion until the marks disappear. By noting the times of appearance and disappearance of the marks corresponding to steps of different density of the wedge, the total exposure to radiation can be estimated. In a modification, the dosimeter is constructed as a double unit. In a further modification, the casing, fluorescent screen and step-wedge are all circular, with cut-out sectors registering with a sector-shaped window in the casing. The light-sensitive element is circular, and is rotated to view exposed parts through the window.

Title: Process for producing phosphatic fertilizer
Inventor: SEYMOUR JAMES ELDRED
IPC: C05B11/08
Filed: 1956-03-13
Abstract: Phosphate fertilizer compositions are made by treating calcium metaphosphate and rock phosphate, dolomite, or limestone in granular form with sulphuric acid.  The metaphosphate is converted to o-phosphate which on further acidulation releases free acid which is neutralized by the phosphate rock, limestone or dolomite.  In Examples, calcium metaphosphate and limestone or dolomite ground to 100/200 mesh are mixed together dry, and sulphuric acid and water added to form a slurry.  This heats up and thickens and may then be ammoniated and cured, or heated in a rotary tumbler up to 800 DEG  F. to form a crust on the nodules produced.  As ammoniating agents, ammonium hydroxide or nitrate may be used with or without urea and formaldehyde.

Title: Plug device for closing a pipeline
IPC: F16L55/128
Filed: 1975-03-26
Abstract: 1516671 Pipe-line closing pigs BROWN & ROOT (UK) Ltd 13 June 1975 [26 March 1975] 12633/75 Heading F2P A plug device for closing off a pipe-line comprises a body for insertion into the pipe-line sealing means encircling the body for sealing engagement with the pipe wall, locking means for holding the body at a required position in the pipe-line, means activated by movement of the plug to measure distance travelled along the pipe-line from a starting position and means responsive to the distance measuring means to effect the expansion of the expandable sealing means. The plug device of Fig. 1 is in the form of a pig comprising a chassis 11, front plate 12, rear plate 13, a plurality of cup rubber 16 retained by bolted flanges 14. A compressed air reservoir supplies expandable sealing bags 21 and pneumatic rams 20, the latter actuating spring biased pawls 22 pivotable to contact the inner surface of the pipe wall. The bags 21 are made of a semi-rigid polyurethane outer casing 26 having a high coefficient of friction with a pipe wall and an expandable inner tubing 27. An airtight housing 50 at the rear of the pig communicates with the pipe-line ahead of the pig through conduit 51a and non-return valve 51 to maintain the housing at the same pressure as that of the pipe-line ahead of the pig. In use the pig is inserted front end first into one end of a flooded pipe-line and that end is then closed with a cap through which compressed air is passed to force the pig along the pipe. An odometer 28 measures the distance travelled by the pig and after a preset distance from a starting position has been reached opens a valve in conduit 30 which causes bags 21 to inflate to retard the pig and pawls 22 to pivot into engagement with the pipe wall to prevent reverse movement of the pig. A pressure sensitive switch in housing 50 activates a sonic pinger 34, when the pressure in front of the pig reaches a predetermined level, whose signals are picked up by external microphones causing the compressed air source driving the pig to be switched off. A second pressure sensitive switch mounted on the rear end of the pig may then operate when the pressure of the drained section behind the pig has reached a desired level, to vent the pressure in rams 20 and bags 21 by opening suitably disposed valves and regulator 37 maintains the pressure in conduits 31 and 32 at a predetermined level above the pressure in front of the pig. In an alternative embodiment rams 20 are omitted and the pawls 22 are merely spring loaded.

Title: Improvements in or relating to television waveform generators
Inventor: PUGSLEY DONALD JOHN DAVEY
IPC: H04N5/06
Filed: 1954-05-03
Abstract: 772,607. Television. PYE, Ltd. April 20, 1955 [May 3, 1954], No. 12799/54. Class 40 (3). A waveform generator for generating the frame blanking pulses of a television waveform comprises a divider arranged in two stages, the first stage having a count equal to the number of lines in a frame blanking pulse and the second stage comprising a plurality of electronic counting units, the count of which, when operating on the output of the first stage, is such as to produce output pulses at a repetition rate equal to the field frequency or at a low integral multiple thereof. In the described embodiment, which is concerned with a 625 line system (although the invention is applicable to 405, 525 and 819 line systems) the first divider stage is supplied with pulses of half line frequency and effects division by the factor 25 supplying output pulses (a) to a chain of electronic counting units B ... F which, by virtue of the feed-back connection from unit F to stages B, C and D (via a buffer stage S) effect a further division by the factor 25 thus producing an overall division of 625 (equal to the number of lines in a frame period). This results in the production of a pulse (f) at frame repetition rate by counter F and of pulses (b) ... (e) by counters B to E respectively. In order to produce frame blanking pulses having the required duration (i.e. containing 25-line pulses) the output pulses from counters C ... F are fed via rectifiers X1 ... X4 to the output line L, the (positive) potential of which is held (by means of potential divider P) at a value equal to that of the D.C. voltage normally present at the output of the dividers so that when any of the rectifiers conduct, due to the positive portions of the pulses (c) ... (b), the potential of line L is brought up to the potential then present at the B counters. This is the case during the intervals 4, 3, 2 and 1. During interval 5, however, none of the rectifiers conduct and the potential of line L then drops, thereby effectively producing a negatively-going pulse which is the required blanking pulse. As shown in Fig. 2, interval 5 has a duration equal to two cycles of pulse train (a) and since the latter pulses are each of 25 half-lines duration the blanking pulse produced is of 25 lines duration. Positivelygoing blanking pulses may be produced in similar manner by connecting rectifiers X5 ... X8, poled as shown, to the opposite sides of the counters B ... F from that to which X1 . . . X4 are connected, the required pulses being developed on line L1. By removing either of the rectifiers X2 or X3 output pulses at twice the frame frequency may be produced.

Abstract: 311,082. General Electric Co., Ltd., Wilson, W., and Dann, T. W. May 1, 1928. Transformers.-In order to obtain from the low tension side 2 of a power transformer a voltage proportional to that at the high tension side 1 for operating relays or measuring instruments 8, there is provided a potential transformer 4 having a secondary winding 6, a main primary winding 5 connected across the low tension side of the power transformer, and an auxiliary primary winding 7 connected in series (either directly or through a current transformer) with the power transformer. The arrangement is such that the current in the main primary 5 induces a voltage in the secondary 6 proportional to the voltage across the low tension side of the power transformer whilst when the latter is under load, current in the auxiliary primary 7 induces a voltage in the secondary 6 corresponding in phase and magnitude to the voltage drop due to the impedance of the power transformer, the two induced voltages combining to produce a voltage proportional to that across the high tension side 1 of the power transformer. For three-phase working, the potential transformer may be built as a single unit with the auxiliary primaries connected in star or in delta.
