Title: Heat exchanger
Inventor: LINGOY GRISTIN
IPC: F28F19/00
Filed: 1995-05-06
Granted: 2001-07-31
Abstract: PCT No. PCT/NO95/00075 Sec. 371 Date Feb. 4, 1997 Sec. 102(e) Date Feb. 4, 1997 PCT Filed May 5, 1995 PCT Pub. No. WO95/30870 PCT Pub. Date Nov. 16, 1995A heat exchanger has been developed with a helical insert (9) permanently mounted in a housing (2). Between the windings in the insert (9) there is formed a helical channel (20) for one heat exchange medium. The insert (9) is designed with a channel (10) for the second heat exchange medium. The heat exchanger is designed with a central tube (13) which is axially movable and rotatable. The central tube (13) is designed with scraper elements for removal of deposits in the channel (20). In one embodiment the scraper element is formed by a helical insert (15) of the same design as the insert (9). The insert (15) is designed with a channel (16) for the second heat exchange medium. In a further embodiment the central tube (13) is designed with one or more scraper arms (23) which may be liquid-cooled. Deposits are often formed on the heat transfer surfaces. A cleaning cycle is performed by means of axial movement of the insert (15) which is mounted on the central tube (13) towards the permanently mounted insert (9), thus causing the heat transfer surfaces to touch each other. A rotating movement is then performed, e.g., a part of a turn, while the surfaces are close to each other or in contact with each other, thus causing the deposits on the two surfaces to be rubbed or scraped off and thereby cleaning the channel (20).

Abstract: 338,053. Bendlin, R., and Urbasch, O. Jan. 9, 1929, [Convention date]. Butter and butter substitutes. - Butter, margarine, and like fats are cleansed and worked by being pressed through channels 5 into vermicellilike threads which are immediately broken by water issuing from a jet 7 against a projection 8 whereby it is evenly diverted radially. Or jets of water may be directed from the circumference 9 of the die 4 towards the centre. The mixture passes through a pipe 11 to a settling tank 12, from which the iloating sponge-like mass is transferred to a press or a centrifuge for removal of the contained washing liquid. When the solid impurities are absent the mixture may be passed directly from the tube 11 to a centrifugal filter. The process may be repeated, the first washing water or solution being acid or alkaline if necessary. Prior to separation of the washing liquid the mass may be coloured and be aromatized by lactic acid bacterial treatment. Or the second and later washings and the colouring and aromatization may take place in the centrifuge. The process enables butter &c. to be preserved with an excess of salt or the like which is removed as the butter is required for sale.

Title: Graphic display systems
IPC: G09G3/32
Filed: 1977-01-06
Abstract: 1521871 Matrix displays and circuits therefor RANDOM ELECTRONICS INTERNATIONAL PTY Ltd 6 Jan 1977 [13 Jan 1976] 00369/77 Heading G5C To present the appearance of a moving display of dot-matrix graphics with a large reduction in the number of light-emitting elements, e.g. LED's or xenon lamps, only a fraction of the elements, e.g. 1 in 8, in each row are active; these may be arranged in complete columns 2, 3 or staggered. The simplest arrangement in complete columns, appears as a view of a moving train of graphics seen through a picket fence. Digital signals are sent in groups, each group setting the state of the lights corresponding to the respective visible elements of the graphics at one constant; the next group, retarded by a "display state period", sets the lights to correspond to the elements of the graphics advanced one column against the direction of motion. The total time to stop a given element of a graphic from one light to the next through the intervening blank elements must not exceed “ second. In an example of 32 columns of 16 lights, adjacent active columns 2,2 are separated by seven inactive ones 4, the display state period being 10 ms.; each LED is fed via an AND gate 7 and SCR latch 14 may be energized briefly but locks on for the rest of the period. A train of symbol codes is fed, e.g. from a key board, to a RAM (Fig. 4, not shown) holding, e.g. 1024 symbols; the leading symbol code is passed to a character generator 5 comprising a ROM (Fig. 5, not shown) holding the format of all symbols including the number of empty columns before and after the symbol proper. A scan is arranged to transfer the columns of the leading symbol, as addressed by the RAM, to the columns of the display, those falling in inactive columns being ignored; in each scan when the leading symbol has been copied, if display columns are still available the succeeding symbol codes are passed to the ROM to provide information for the latter part of the display. After each period the positions of the columns passed from the ROM are stepped one column against the direction of motion. Data may be passed either in parallel mode in which one line 6 per row is provided, switched to the appropriate column by the "column" input 12 of the AND gates as data for each active column is supplied, or in series mode each active column may have a memory, e.g. a shift register (Fig. 6, not shown), the data bits for the first column being supplied to its memory as a 16-bit word. A shift register sufficient to store the 16 bits for each of the 8 periods until the image on one active column reaches the next is provided between each pair so that data fed to the first progresses along the display in successive periods. After each entry of a 16-bit word an "intensify" pulse to the "column" input of all AND gates intensifies and latches the required LED's. Complete parallel or series, or hybrid, addressing of rows and columns may be provided.

Filed: 1974-01-07
Abstract: 1457548 Converting SONY CORP 7 Jan 1974 [19 Jan 1973] 693/74 Heading H2F [Also in Division H3] In a transistorized single-ended push-pull sweep generator a switch conducts during the flyback to provide the power supply to the generator and to charge a plurality of capacitors in series and becomes non-conductive during the sweep whereby the capacitors in parallel provide a lower supply voltage. Power dissipation is thus reduced. The circuit may also provide voltage during the flyback greater than that of the supply. In Fig. 7 the voltage across the deflection coil during the retrace is applied to the gate of a gate-controlled switch to turn it on for the duration of the retrace. Accordingly the circuit is supplied with the sum of the supply voltage E 0  and the voltage across a capacitor 24. At the same time capacitors 21a and 21b are charged in series to ¢E 0 . During the sweep the capacitors 21a and 21b are connected through diodes in parallel to supply the generator with the ¢E 0  voltage. At the same time capacitor 24 recharges via resistor R23 to ¢E 0 . In Figs. 3 and 6 (not shown) alternative connections of capacitors 21a and 21b are used and Fig. 5 includes an additional capacitor so that <SP>1</SP>/ 3 E 0  is produced. The G.T.O. rectifier may be replaced by a transistor or thyristor and its control voltage may be obtained from the deflection coils via a CR differentiating circuit.
