Title: Apparatus for cooling television cameras, particularly in nuclear reactors
Inventor: BARRATT PETER
IPC: G21C17/08
Filed: 1960-04-29
Abstract: 961,832. Thermo-electric devices. PYE Ltd. April 28, 1961 [April 29, 1960], No. 15132/60. Heading H1K. [Also in Division H4] The absorption of heat due to the Peltier effect at the inner junctions of series connected rings 10, 11 (Fig. 2) of P-type and N-type semi-conductor material, respectively, when a current flows, is utilized to transfer heat from an axially mounted television camera tube 1 to a heat sink 14 in thermal contact with but electrically insulated from the outer junction of the rings. The semi-conductor material may comprise bismuth or antimony telluride or gallium arsenide. Figs. 3 and 4 show a variation in which the camera tube 20 is cooled by the similar arrangements each comprising an inner aluminium lining 21 the space 22 between which and the tube is packed with metal wool (or a radiant resistant grease of good thermal conductivity) and to the outer surface of which Peltier devices having the form shown at 23 are clamped, electrically insulating (e.g. mica) wafers 24 being employed if a plurality of Peltier devices are used. The other junctions of the latter devices are in thermal contact with (and electrically insulated from, if necessary) a heat sink comprising an outer corrugated aluminium case 25 the space between which and the inner lining 21 is filled with thermal insulating material 27 to reduce heat conduction back to the assembly. The invention is particularly concerned with the cooling of television cameras which are used inside nuclear reactors and when the ambient temperature is very high an additional heat-sink consisting of two concentric metal cylinders the space between which is filled with a material having a high latent heat of fusion and a melting point comparable with that of the operating conditions may surround the complete " Peltier-coolec " assembly. By employing a vacuum heat insulating arrangement the latter assembly may be pre-cooled before operation. Additional cooling of the assembly may also be provided by means of a flow of cooling gas supplied via a hose connection to a vortex tube from which it flows through an inner tubular aluminium shell containing the " Peltier-cooled " camera and returns via a coaxial outer tubular steel shell (Fig. 5, not shown). In the latter arrangement the inner shell may also contain associated amplifiers and motors. The assembly may be sealed employing a transparent seal at the end adjacent the camera tube target and the outer shell may carry the camera lens together with mirrors, lights and grabs &c. Specification 906,406 is referred to.

Title: Method and Apparatus for Feeding and Compacting Finely Divided Particulate Material
IPC: B65G69/20
Filed: 1969-03-24
Abstract: 1,198,963. Discharge of airfree powder. CARTER ENG. CO. 24 March, 1969 [2 April, 1968], No. 15203/69. Heading B8A. Powder from hopper 3 is discharged down through sleeve 4 by conveyer screw 10 secured to shaft 8 the sleeve 4 being provided with perforations 26 and with external mesh screen 27 so that suction may be applied to chamber 6 of housing 2, by which air contained within the powder is sucked out through the sleeve and discharged to leave the discharged powder free from air. Powder coats the inside of sleeve 4 and this difficulty is removed by lip 11 of the screw 10 which scrapes the inside of the sleeve and by positive gas pressure which is applied in the chamber 6 and penetrates the sleeve 4 to blow away the lining. Application of gas pressure (Fig. 4).-The chamber 6 is divided into sub chamber 6a and 6b by longitudinal partitions 30 and 32. Suction is applied to sub chamber 6a at 34 via valve 38 from source P and positive gas pressure is applied at 50 via valve 54. To sub chamber 6b suction is applied at 40 via valve 42 from the source P and gas pressure is applied at 56 via valve 58. Operation.-Normally suction is applied at 34 and 40 to free the powder from air. But at periodic intervals the powder has to be removed from the inside of the sleeve 4. This is effected by closing valve 38 to shut off the suction at 34 and by opening 54 to permit the entrance of gas pressure above atmosphere at 50. Then air blows in at 50 and out at 40 to blow away the powder on the inside of sub chamber 6a. Then valve 54 is closed to shut off the gas pressure of 50 and valve 38 is opened to permit suction at 34. Additionally the suction at 40 is closed by closing valve 42 and the gas pressure at 56 is opened by opening the valve 58. In this way gas flows from 56 to 34 and blows away the powder formed on the inside of sub chamber 6b. Inlet of air from the bottom of the sleeve is prevented by a rubber valve attached thereto.

Abstract: 1431817 Condensers B G ANDERSSON and B R ANDERSSON 31 March 1973 15596/73 Heading F4H A refrigeration system having a compressor 52, a capillary 57 and an evaporator 50 is characterized in that the condenser is formed of two parts, one 54 having vaporized refrigerant bubbling through condensed refrigerant, and the second 56 being air cooled. The two parts are preferably combined into a single air-cooled condenser wherein the vaporized refrigerant is forced to pass through a quantity of condensate which is sufficient to ensure that the vaporized refrigerant is converted into the liquid store. As shown in Fig. 2, a vessel 1 containing the condensate is encased within a housing 10; the vessel 1 having both internal and external helical fins. The vapour enters the vessel 1 by nozzles 21 in branch conduits 18 of the conduit 15 leading from the compressor. As the vapour bubbles through the condensate, the additional condensate so formed continuously flows in a helical path towards an exit 31, and is thereby further cooled by the air forced through the housing 10 by an impeller 11. The impeller 11 is controlled by a thermostat 29. In Fig. 3, a number of tubes 6 are disposed in a vessel 1 which is divided by a horizontal partition into two compartments 3, 4. The vapour is bubbled through condensate in the top compartment via nozzles 21, the excess condensate running down the vertical tubes 6 into the bottom compartment. The vaporized refrigerant may be precooled by an additional heat exchanger 13 and by independent cooling means provided within the partition.

A load 1 forming a control element of a system is supplied from an A.C. source by way of a rectifier bridge 2 and a thyristor 6 across the output terminals of the bridge. Firing pulses for the thyristor 6 are developed by a control circuit which includes a pulse generator 4 and a sawtooth generator 3. The control circuit is energized from the output terminals of the bridge and the frequency of the sawtooth generator 3 is much lower than the output frequency of the pulse generator 4. The outputs of the generators 3, 4 are applied to a control device 5, the output of the generator 4 being by way of a device 7 which senses the deviation in the electrical parameter which it is desired to correct. The effect of the sensor 7 upon the pulses developed by the generator 4 is to reduce the magnitude thereof as the deviation is reduced. The control device 7 differentially compares the two input signals thereto and produces output signals to fire the thyristor 6, the thyristor being fired for a long period when the pulse amplitude applied from the sensor 7 is high, the period reducing as the pulse amplitude reduces such that the correction reduces as the parameter approaches its correct value.

Abstract: 1472753 Analogue-to-digital conversion NIPPON KOGAKU KK 10 April 1974 [12 April 1973] 15954/74 Heading H3H [Also in Divisions G1 and G2] A light metering circuit comprises a photoelectric device R1 for producing a first analogue signal V1 representing brightness, a reversible counter CU, means R A  to R D  for producing a second analogue signal V2 representing the count stored in the counter and means Q2, Q3 for comparing the signals and stepping the counter backwards or forwards depending on the difference between the signals so that the count n continuously represents the brightness B. As shown the count is used to indicate and control camera shutter speed. In Fig. 1, a differential amplifier Q2, Q3 opens an AND gate G1 if V2>V1 whereby pulses from a generator PG decrease n and open an AND gate GZ if V1>V2 whereby pulses increase n. When V1=V2 the count n stays constant as long as the brightness remains constant. V2 is determined by that one of resistors R A  to R D  connected to the conducting stage of counter CU. Preferably, R A  = 2R B  = 4R C  = 8R D . A lamp light emitting diode or liquid crystal indicator IND indicates the shutter speed represented by n and, upon opening a switch S a timing capacitor C is charged by a current I C  dependent on a selected resistor R A -R D  to control the shutter opening period. Figs. 4, 5 and 6 show minor modifications of Fig. 1; Fig. 4 takes a single output from the differential amplifier or one AND gate and inverts this output for the other AND gate, Fig. 5 uses two pulse generators instead of the AND gates, and Fig. 6 uses a single output, an inverter and two pulse generators. In Fig. 2 for SLR cameras a first differential amplifier Q18, Q19 is controlled by a bridge circuit including a photoconductor R 11  and a resistor R 12  set according to A.S.A. and f no.; a second Q20, Q21 is controlled by the counter CU and a third Q12, Q13 compares the outputs of the first two to control the counter. When the mirror hinges up a switch S1 opens to store the count and when the shutter opens a switch S2 closes and a second pulse generator PG2 steps down the counter to zero whereupon a gate G14 de-energizes an electromagnet Mg to close the shutter. The shutter speed is indicated by lamps L1-L4. The circuits may alternatively be used for diaphragm control or in exposure meters.
