Title: Improvements relating to cathode ray tube displays
Inventor: RICHARDS MOSTYN THOMAS
IPC: G01R13/22
Filed: 1964-11-17
Abstract: 1,113,017. Cathode-ray tube circuits; pulse shaping and relay operating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 2 Nov., 1965 [17 Nov., 1964], No. 46808/64. Headings H3P, H3W and H4T. The area enclosed by a recurrent closed loop trace on a cathode-ray tube is determined by superimposing thereon a synthesized trace the dimensions of which are varied to make it match the unknown trace by means of calibrated adjusting means the settings of which enable the area to be determined. The invention is described in connection with the measurement of the area enclosed by the rhomboidal or parallelogram trace indicative of the energy loss per cycle in the dielectric loss measuring apparatus of Specification 951,482 such trace being displayed in rapid alternation with the synthesized trace. In the arrangement shown one pair of deflecting plates of the cathode-ray tube (CRT) is continuously fed with an A.C. voltage derived from the transformer T in the H.T. supply of the apparatus whilst the other pair is supplied alternately via a relay changeover switch R operated once per cycle of the A.C. supply, with the output of the dielectric loss apparatus (APP) and with the output of a wave shaper circuit including calibrated adjusting means VR1 (for width) and P2 (for amplitude) operation of which allows the shape (area) of the synthesized trace to be varied. The wave shaper, which is supplied with A.C. voltage from the heater winding of the transformer T via a phase shifter and a buffer amplifier and filter operates by charging a capacitor C8 through C6 on the positive half-cycles and through C7 on the negative half-cycles the voltage across C8 (the shaped output voltage applied to the CRT) following the sinusoidal waveform of the input until the peaks (positive and negative) are reached and remaining at this value until the input voltage via RF2 or RF3 falls below (in the positive and negative directions) the peak value by an amount equal to the voltage remaining on C7 or C6 from the previous half-cycle after which it again follows the sinusoidal waveform. The time for which the voltage across C8 remains constant is determined by the voltages remaining on C6 and C7 and these are determined by VR1 adjustment of which determines the width of the trace on CRT. When the phase shifter is adjusted to bring the sinusoidal portions of the shaped wave into phase agreement with that of the sinusoidal waveform applied to the other deflecting plates of the CRT a trace of rhomboidal form is obtained. The relay drive for supplying the operating coils Ra Rb of the change-over switch R includes two gas-filled diodes the firing of one of which prevents, by virtue of the voltage drop in the associated resistor R1 or R2 and capacitor C2, the firing of 'the other diode, such voltage drop however serving to prime the latter diode so that on the next positive half-cycle via RF1, by which time the first diode will have extinguished, the second diode preferentially fires.

Abstract: 1331306 Cooling gases by direct contact with liquids; indirect heating systems GUSTAV OSPELT HOVALWERK AG 5 Oct 1970 [3 Oct 1969] 47306/70 Headings F4K and F4U [Also in Division B1] An installation for treating exhaust gases by contacting them with a cleaning and cooling liquid (e.g. in the cleaning and cooling of hot gases from a burner, or in the humidifying of room air circulated through the installation, comprises a casing containing an annular rotating mass 32 of plates providing between adjacent plates flow channels for the gases flowing radially either inwardly (as in the form shown), or alternatively outwardly, through the mass in contact in said passages with the liquid supplied to the channels from a spray nozzle system 40-44 rotating with and independently of the mass. The cleaned and cooled or humidified gases may pass out of the casing either directly as shown, or via an independently rotated fan (81, Fig. 4). Or alternatively the treated gas may pass through a further rotating cleaning &c. stage (Fig. 5) before reaching the casing outlet. The liquid may contain an absorption substance such as caustic potash to remove sulphur from the gases. The gas washing liquid discharges into the mass by way of pipes 44 mounted on a shaft 25 rotating in a direction opposite to that of the mass. The pipes 44 may terminate in individual nozzles (80, Figs. 4, 5) or as shown in an elongate nozzle comprising a longitudinal slit in a transverse duct arrangement 40, 41, 42, said nozzle being variable in size by an adjusting screw 43. The plates of the mass 32 may be corrugated, flat or curved (Fig. 17) and may be perforated. As shown in Fig. 14 the passages formed between adjacent plates such as 99, 100 may provide an undulating flow path of varying transverse cross-section formed e.g. by relatively displacing the corrugations of adjacent plates, or by plate corrugations of assymetric form; and the flow path may contain spacers 101 and a perforated plate member 98. Alternatively, Fig. 15, a tortuous flow path 106 may be provided between adjacent flat plates 102, 103 by a sieve plate 104 and spacers 105. Adjacent plates may be spaced apart by resilient means such as rubber bands 31, Fig. 2. The plates may be made from or coated with a synthetic material and the arrangement is said to be self-cleaning. Fig. 1 shows an arrangement in which a heating system 12, 13, 14 is heated indirectly by combustion gases from a burner 1 which are cleaned and cooled in the rotary apparatus such as shown in Fig. 2 before exhausting to atmosphere via a fan 4 and duct 16. The cleaning and cooling liquid used in the apparatus is circulated in a closed system (e.g. 5, 6, 11, 15, 17) including a vessel 10 in which the heat exchanger 13 of the heating system is immersed. The cleaning and cooling liquid circuit may include a jacket 2 around the combustion space having duct connections 7, 9 to the circuit.

Title: Method of, and apparatus for, controlling the specific gravity of a heat-treated liquid
IPC: A23L2/10
Filed: 1962-12-21
Abstract: 956,224. Sterilising liquids. ALPURA A.G. Dec. 21, 1962 [Jan. 4, 1962], No. 48309/62. Heading A2D. [Also in Division G1] The end specific gravity of a liquid is controlled in relation to its initial specific gravity in a plant in which the liquid is heated by direct contact with steam and then cooled by expansion with partial evaporation, by varying the difference between the expansion temperature and the initial temperature of the liquid before heating in dependence on variations in at least one of these two temperatures. The sterilisation or pasteurisation of milk, fruit juices and pharmaceutical products are instanced. According to an example, milk pre-heated to a temperature t3 by passage through pre-heater units 3 and 5, Fig. 1, is sterilised by shorttime heating to a temperature t4 of 150‹C. by steam injected from a line 8 at a temperature of 175‹C. and a pressure of 9 Kg. per sq. cm.; the regulation of the steam valve 11 by a temperature-sensitive element 9 ensures that the heating temperature t4 is kept constant. The heated milk is colled rapidly in an expansion chamber 12, held under vacuum by a condenser 17, to an expansion temperature t5 of about 80‹C. and the cooled milk is drawn off along a line 14. A comparator unit 30 and modifying unit 32 regulate the valve 25 supplying heating medium to the pre-heater 5 in accordince with a graph, Fig. 4 (not shown), depicting the requisite variations in temperature difference t5-t3 for a range of expansion temperatures t5 under the operational conditions whereby the specific gravity of the treated milk is kept at the same value as that of the raw milk introduced into the plant. In the regulating system shown in Fig. 2, the measurement of temperatures t3, t5, by elements 41, 42, which are filled with a vapourisable liquid and produce inside bellows capsules 44, 43 pressures corresponding to the temperatures sensed, is transmitted through a calibrated threedimensionable cam 51, Figs. 2 and 3, to the stem 52 of the valve 25. A change in the temperature difference t5-t3 causes the cam to rotate about its shaft 50, while variation in the expansion temperature t5 produces an axial displacement of the cam. In alternative embodiments (i) the temperature difference t5-t3 may be calibrated against the initial temperature t3, (ii) to keep constant a desired end value for the specific gravity, the temperature difference between the initial temperature t3 and the expansion temperature t5 may be adjusted according to variations in both these temperatures, Figs. 6 and 7 (not shown), and (iii) the temperature may be regulated and adjusted by varying the expansion pressure and hence the expansion temperature, Fig. 5 (not shown).

Abstract: 486,486. Current meters; temperaturevariable resistances. BRITISH THOMSONHOUSTON CO., Ltd. July 8, 1937, No. 18950. Convention date, July 8. 1936. [Class 37] [Also in Group XXXV] A moving-coil instrument has a cylindrical core 13, permanently magnetized along a diameter, which is situated between segmental magnets 14, permanently magnetized radially, and is spaced therefrom so as to form an annular gap 12 in which the movable coil 11 is free to rotate. The segments 14 are joined to a ring 15 of soft iron or other material of high permeability, for example by die casting. The permanent magnets 13, 14 are formed of material of high coercive force, such as cobalt steel or an alloy of aluminium, nickel, and.iron containing 16 per cent of aluminium and 20 per cent of nickel with or without a small percentage of cobalt. Alternatively sintered magnetic oxide material composed of magnetite, ferric oxide, and cobaltic oxide, such as described in Specification 463,783, [Group XXXV], may be employed. The surrounding ring 15 may be of permanent magnet material and permanently magnetized. The core 13 may have an axial hole to accomodate a shaft 17 supporting the winding 11. Such a magnetic system has a short magnetic path of low reluctance and enables a high flux density to be obtained in the air gap 12. A relatively large torque is thereby obtainable, enabling a pen-carrying arm to be fixed directly on the shaft 17. The coil 11 may be connected across a shunt resistance in the main circuit, in series with a temperature-compensating resistor consisting of an annealed crystal of silver tellurium alloy or a disc of annealed tellurium having a resistance of one-third of that of the coil 11.
