Abstract: 1,055,437. Evaporators, film-type with vapour-compression; distillation of water. GARRETT CORPORATION. Oct. 15, 1963 [Oct. 16, 1962], No. 40696/63. Heading B1B. In an evaporator/condenser unit 23 wherein the liquid to be evaporated flows in film-form down the inner surfaces of externally-heated vertical tubes, the vapour evolved from the liquid being passed to a compressor 34 in order to raise its temperature and the compressed vapour being introduced through conduit 35 into the shell of unit 23 where the vapour condenses and serves a heating-medium. the inner surfaces of the tubes 58 are formed with flat or slightly curved longitudinal ridges 80 (Fig. 6) and some of the liquid being evaporated flows down the ridges in thin uniform films while the remainder flows down the grooves 78. The apparatus is particularly suitable for producing distilled water by heating saline water under reduced pressure .The saline water is pumped through ion-exchanger 12 where heavv metal ions (Cu, Ni, Fe) are exchanged for zinc or magnesium. Part of the saline water then flows through heat-exchanger 14 where it is heated to about 145‹F by the distilled water withdrawn from the shell of unit 23 through conduit 24, and the remainder of the saline water is heated to 145‹F. in heat-exchanger 16 by residual brine withdrawn from unit 23 through conduit 30. The two streams of preheated saline water are united, and the united stream is heated to 165‹F. in heat-exchanger 18 by hot exhaust gases from gas-turbine 37, which drives compressor 34. The hot saline water then flows into the top of the evaporator 23 via throttle-valve 20 and deaerating tank 21, which is connected to vacuum pump 43 by conduit 45. Pump 43 also evacuates the shell of unit 23 via conduit 44. A portion of the residual brine may recirculated through conduit 28 to the top of the evaporator. The tubes 58 are supported between upper and lower header plates in unit 23, the upper ends of the tubes extending a short distance through the upper plate. The manner in which the saline water is distributed on to the inner surfaces of the tubes, and the vapour is guided into conduit 32 leading to the compressor, is described in conjunction with Fig. 3 (not shown).

Abstract: 1,159,537. Article-tumbling device. ATLANTIC RESEARCH CORP. 6 Sept., 1967, No. 40728/67. Heading A6H. A game device for tumbling articles, such as dice, comprises a tumbling platform adapted to receive such articles, means for vibrating said platform, means including a proximity circuit and sensing means for causing the actuation of the vibrating means in response to the approach of an object towards the sensing means and for maintaining the continued actuation of said vibrating means during the presence of the object. If desired there may be incorporated in the device a resistance-capacitance timing circuit for ensuring actuation of the vibrating means for at least a predetermined time period, the control being activated simultaneously with the actuation of the proximity circuit. In figure 2 the sensing plate 18, in the form of a ring, senses when a hand is brought within critical proximity and the proximity circuit (shown in Fig. 1) is brought into use; current flows through line 30 to motor 64 causing rotation of cam 68 by cam 66 and the platform 54 vibrates and so shakes the dice 56. A long as the participant's hand stays within the operational range of the proximity circuit the dice will continue to mix. A delay feature in the feedback circuit formed by a resistor 32 and capacitor 34 in the proximity circuit ensures that the mixing of the dice continues for at least a predetermined period, e.g. half a second, even if the person's hand is withdrawn before this predetermined period elapses.

Abstract: 1,235,479. Electronic calculators. BELL PUNCH CO. Ltd. 10 Sept., 1968 [15 Sept., 1967], No. 42234/67. Heading G4A. [Also in Division H1] Two gas discharge display tubes 1 (see Division H1) each having two anodes 2, 3 and two sets of cathodes 0-9 are utilized in a dynamic read out circuit for two multi-stage registers 21 and 24 of a calculating machine. The anodes 2, 3 of the tubes are connected through switches or switching circuits 20, 23 to respective stages of the registers. A pulse generator 22 which circulates the numbers stored in the stages is connected to a driver 25 which steps in the reverse direction switches or switching circuits 26 connected to the commoned cathodes 0-9. Thus if the number 7 is stored in the first stage of register 21, the third pulse of an applied train of ten pulses will cause the stage to move to the zero position and emit a carry pulse to energize anode 3 of the first tube. At the same time the switches 26 will have stepped in the reverse direction to energize cathodes 7, so a 7 is displayed in the lower half of the first tube 1.

Abstract: 1,109,200. Control of A.C. motors. GENERAL MOTORS CORPORATION. 22 Sept., 1966 [7 Oct., 1965], No. 42368/66. Heading H2J. [Also in Division G3] The stator windings A, B, C, of an induction motor are energized in sequence by means of silicon controlled rectifiers 31, 32, 33, and the speed of the motor is determined by regulating the firing-angles of the rectifiers. A Zener diode 36 is fed from bridge rectifier 10, connected to one supply phase, to produce a reference potential, whilst a tachometer generator 11 is driven by the motor to provide a speed-responsive signal which is adjusted by potentiometer 14. A relaxation oscillator comprises a capacitor 23 which is charged in accordance with the speed error signal to control the conduction-angle of unijunction transistor 20 and to produce a master firing pulse across resistor 22, this pulse being terminated by the firing of silicon controlled rectifier 50. The pulse across resistor 22 is amplified by transistor 75 associated with transformer 76 whose secondary winding 78 is connected in the firing circuit of rectifier 31 in series with the stator winding A. The pulse induced in secondary winding 77 triggers multi-vibrator transistor 25 to render transistor 26 non-conductive whereby transistor 85 conducts for a period to energize transformer 86. The collapsing field of the transformer causes secondary winding 88 to produce a second trigger pulse which fires rectifier 32 and is spaced by 120 electrical degrees from the master trigger signal. Secondary winding 87 is connected to multi-vibrator 29, 30, for firing rectifier 33 after a further delay of 120 electrical degrees. In another arrangement, the multi-vibrators of both slave trigger circuits may be operated to the alternate state by a signal from the master trigger circuit, potentiometers 58, 68, being adjusted to produce delays of 120 and 240 degrees respectively. The motor may be of the single-phase type, in which case the slave trigger circuits are omitted. The stator windings may be delta-connected, with back-to-back rectifiers in each phase, Fig. 2 (not shown).

Abstract: 1,261,059. Valves. GENERAL ELECTRIC CO. 5 Sept., 1969 [12 Sept., 1968], No. 44002/69. Heading F2V.  In a valve through which fluid flow can take place at two different and basic flow rates, the valve outlet 11 is comprised of two members 14 and 18 which are in mutual screw-threaded engagement, in combination afford a single outlet port 22, and which have their other ends projecting into the interior of a flow chamber 4 having an inlet (8, Fig. 1, not shown). The projecting innermost ends of members 14 and 18 constitute seats for a compound closure member comprised of two relatively movable and concentric closure members 39 and 44 respectively, with a projection 40 on member 39 being attached, through a lost-motion spring coupling, to a compensating bi-metallic strip 35, the other end of which is coupled to a controlling bimetallic strip 33 having disposed there around an insulating sheet 51 and a heating coil 50. In operation, and in the absence of current in coil 50, closure members 39, 44 engage their respective seats with any fluctuations in ambient temperature being compensated for by strip 35, this latter bi-metallic strip flexing oppositely to the direction of flexing of strip portion 34 of bimetallic strip 33. Upon applying a current to coil 50, bi-metallic strip 33 flexes and so compresses spring 42 until closure member 39 is forced to detach from its seat, such detachment permitting a limited flow from chamber 4 and through port 23 to outlet 22. Further flexing of strip 33 results in a ledge 46 on member 39 engaging a projection 45 of the inner valve member 44 and hence raising it from its seat with the result that additional flow can then take place through the seat and on to port 22, the amount of additional flow being dependent upon the disposition of member 44 in relation to its seat and hence upon the degree of flexing of strip 33.
