Abstract: 1,027,847. Sterilizing liquids. A.P.V. CO. Ltd. Dec. 29, 1964 [Jan. 20, 1964], No. 2445/64. Heading A2D. An apparatus for heat treating fluids comprises a regeneration heat exchanger through one side 13 of which the process fluid passes on its way to a treatment heat exchanger 15, a flow diversion valve 16 for selectively recycling the process fluid or passing it to the other side 17 of the regeneration heat exchanger and a fluid outlet, an auxiliary fluid inlet 14 between the side 13 of the regeneration heat exchanger and the treatment heat exchanger 15, a drain outlet 23 in the recycling line 22, and a further drain outlet 21 in the output line 19. In use, hot water from an auxiliary heat exchanger 24 is fed via the auxiliary inlet valve 14 through the treatment heat exchanger 15 and the recycling line 22 to drain at the outlet valve 23. When the water leaving the exchanger 15 reaches the treatment temperature the valve 16 changes over and directs the water to the finished product side of the regeneration heat exchanger, to a cooling exchanger 18, and to drain via the outlet valve 21. Process fluid, e.g. milk, is then brought into a balance tank 11, passed to the regenerator 13 and as soon as it reaches valve 14 this is changed over so that the milk follows the starting water through the apparatus. When the milk reaches valve 21, this valve is changed over to direct the flow to the outlet. A second embodiment (Fig. 2 not shown), particularly designed for the ultra high temperature treatment of milk, comprises a two stage plant with a holding tank and a homogeniser and includes two heating sections and two regenerating sections.

Title: Scanning system for colour television
Inventor: URTEL RUDOLF
IPC: H04N11/00
Filed: 1950-02-03
Abstract: 673,202. Television. LORENZ AKT.-GES., C. Feb. 3, 1950 [Feb. 5, 1949], No. 2832/50. Class 40 (iii). [Also in Group XXXV] In a colour television system in which the image detail of each line, Fig. 2, is arranged in separate zones 2, 3, 4 according to colour, the analysing and reconstituting cathoderay beams are caused to scan all the component colours during the scanning of each line by subjecting the beams to a transversal deflection as shown during the traversal of each line. The frequency of the transversal deflection is the frequency of line deflection multiplied by about half the number of picture elements per line. To prevent the scanning becoming displaced in relation to the colour component zones a test area having the centre zone masked is situated at one border of the image and the scanning motion is continued over this area to derive a correcting signal dependent upon the difference in the time the beam dwells on the upper and lower colour zones. At the transmitter, Fig. 1, object 6 is projected through objective 7 having red, green and blue sections on to lens grating 8, each lens of the grating forming a line on target 9 divided into three colour zones. The analysing beam is scanned under control of line and frame coils 13, 14 and subjected to the further transversal deflection by means of auxiliary generator 19 energizing deflection plates 21. Output from the signal plate 10 passes through video amplifier 15. The signals derived during the scanning of the test area are blanked out in circuit 16 and passed through tube 22 to a bridge circuit comprising diodes 17, 18. The circuit is also supplied with signals from auxiliary generator 19 and derives the converting potential across circuit 23. The potential is applied to vary the resistance of tube circuit 20 generating the frame saw-tooth voltage. At the receiver the line and frame deflections are synchronized with those at the transmitter and a similar transversal deflection is applied, the auxiliary signal being derived from the line frequency. The signals derived from the scanning of the test area at the transmitter are transmitted to the receiver and recorded as light emitted from a test area situated in the same position as that at the transmitter. The light emitted affects a photocell which is arranged to produce a converting bias for the frame scanning as at the transmitter.

Title: Improvements in or relating to sealing means
Inventor: WIGG RAYMOND ERNEST
IPC: F01D11/04
Filed: 1957-01-25
Abstract: 834,923. stuffing-box substitutes. ROLLSROYCE Ltd. Jan. 21, 1958 [Jan. 25, 1957], No. 2876/57. Class 122 (5). Sealing means between the shaft 12, Fig. 1, of a gas-turbine and its housing 10 comprises a sealed sleeve 28 mounted on the housing and encircling the shaft with a small clearance space which at one end communicates with the turbine chamber 18 and at the other with a liquid delivered at a higher pressure than that of the gas in the chamber 18, and helical grooving 26 formed in one of the surfaces bounding the clearance space. As shown in Fig. 1, the sleeve 28 surrounds a second sleeve 19 fixed to the shaft 12 and is connected to one end of a bellows 29, which, at its other end, is attached to a member 30 mounted in the housing 10, the surface of the sleeve 19 being formed with the grooves 26. The sleeve 28 is formed with a radial surface 32 which, when the shaft is stationary or running at slow speed, is urged into contact with a ring 20 mounted on the shaft 12 by the pressure of the gas, such as helium, contained within the chamber 18. In operation under normal running conditions, liquid, such as oil, is fed by a pump 35 through a pipe 36 into a chamber 34 at a higher pressure than that of the gas and thereby moves the surface 32 away from the ring 20 until a flange 33 abuts the member 30 so that liquid then tends to flow into the clearance space between the two sleeves 19, 28. The dimensions of the clearance space and the dimensions and handing of the grooves 26 are so selected that the oil drops in pressure as it moves towards the chamber 18 and the gas, which tends to leak from the chamber, rises in pressure until at a certain point between the ends of the sleeve 28 an oil/gas interface is formed. In order that the seal may be independent of variations in gas pressure in the chamber 18, a constant high-pressure gas supply may be admitted through a duct 24. The sleeve 19 is provided with a finger 21 which rotates in a groove 22 formed in the housing 10 so that any gas contaminated with oil vapour is discharged through an outlet 23. In the modification shown in Fig. 3, the oil-pump 35 is dispensed with and oil supplied to a bearing 16 is pressurized by means of helical grooves 41 formed in the surface of the main shaft 14, of opposite hand to the grooves 26. The grooves, in co-operation with a sleeve 40 surrounding the grooved surface, pump the oil into the chamber 34a to act upon the flange 33 in the manner previously described. To prevent any build-up of excessive pressure in the latter chamber, a relief valve 58 is located in a duct 57 leading to an oil drain and is urged into the closed position by a spring 59 and the pressure of the gas in the chamber 18 acting upon a diaphragm 62. A spring-urged rubbing-collar type seal 51a is mounted on a spherical seating 50 formed on the sleeve 40, although, in a further modification, this seal may be replaced by a bellows.

Systems depending on static transformers; regulation, automatic.-In automatically regulating voltage by means of a transformer having a tapped secondary winding, a voltage relay sets in action a reversible motor operating a drum controller, which acts as a master-controller to a number of contactors adapted to change the tapping-connections. The system is provided with interlocking auxiliary contacts, and with an impedance coil arranged to prevent short-circuits across the transformer taps. Fig. 2 is a diagram of the essential features of the system, the power circuits being shown in the lower half and the control circuits in the, upper half of the diagram. Fig. 1 shows the detailed arrangement of the relays and switches in the circuits. Fall or rise of potential in the conductors 3 affects a two-way relay 16 which acts through timed relays and interlocking switches 57, 58, 59, 60 to start a reversible motor 19 coupled to a drum controller 20. Displacement of the drum from the normal position, in which a row of contact fingers 31 - - 42 rest on the horizontal line between the segments 46, 47, effects the closure of one or more contactors 21, 22, 23 connected to tappings of the secondary winding 14 of a potential transformer 10. The voltage thus tapped off is fed through an inductance coil 28 and reversing contactors 24, 25 to the primary 7 of a series transformer 6 which thus supplies automatically a positive or negative boost to correot the initial change of potential.
