Title: Constant level evaporator
Inventor: FONSECA ANDRE
IPC: B01D1/00
Filed: 1963-09-23
Abstract: 997,613. Evaporators ; constant-level device. COMMISSARIAT A L'ENERGIE ATOMIQUE. Sept. 23, 1963 [Sept. 21, 1962], No. 37417/63. Heading B1B. A constant-level of liquid is maintained in evaporation-dish C 1  by a closed liquid-supply tank R 1  from which the liquid flows into the dish through a downwardly-inclined duct D 1  which is joined to the bottom of the tank and which dips into the dish C 1  at the required constant level. The tank is provided with an air-supply tube T 1  which is open to the atmosphere at the upper end and which terminates at the lower end in a capillary orifice 3 close to the mouth of the inclined duct. The dish C 1  is heated electrically by coil 17 which is automatically switched off, when tank R 1  becomes empty, by means of mercury pressure-gauge 9 which has two branches 10, 11. The wider branch 10 is connected by tube 14 to the inside of the tank, while the other branch 11 is open to the atmosphere. Platinum wires 12, 13 extend into branches 10, 11 respectively ; and the two wires are connected to relay 15 which acts, via switch 16, to interrupt the current to heating- coil 17 when both platinum wires are in contact with the mercury in gauge 9. When the evaporator is in operation, wire 13 is not in contact with the mercury and the heating circuit 17 is closed.

Title: Improvements in and relating to coin-freed apparatus for vending liquids
IPC: G07F13/02
Filed: 1928-12-19
Abstract: 324,483. Henderson, W. Dec. 19, 1928. Moving-chamber apparatus. - Comprises detailed improvements in coin-freed apparatus, for vending liquids in measured quantities, of the type described in Specification 282,865, including means for varying the capacity of the measuring vessel within fine limits and for screening the mouth of the delivery pipe to prevent tampering. The hoisting-gear for the container is arranged within the storage receptacle for the fluid, to prevent the latter being spilt over into the insulating chest. The container 9 is connected by a chain 17 to a chain wheel 18 that can be rotated through chain gear 24 and bevel gear 22 by turning the handle 20. The handle is turned first in one direction to lower the container from the dotted-line discharge position into the fluid, thereby stirring the later, and then reversed to raise the filled container to the discharge position where the fluid is delivered through the members 12, 7 to the purchaser's receptacle. The angle of tilt of the container, and therefore the capacity, is varied by adjusting the position of the guiderest 13 by screw-and-nut mechanism 14, 15. A hinged weighted lid 9<b> also is fitted to the container, which opens by gravity in the tilted discharging position. The raising of a sliding door 8 to insert the purchaser's receptacle, causes a stop 33 to be moved through the medium of a cam 35 over the end of the delivery pipe to prevent tampering, while re-closing of the door reopens the pipe.

Title: Improvements in or relating to a process for the production of solid soot aggregatesfrom an aqueous soot suspension
IPC: B01J2/10
Filed: 1960-11-04
Abstract: <PICT:0962342/C1/1> Solid soot aggregates are continuously produced from an aqueous soot suspension by stirring with at least a calculated minimum proportion of a water-immiscible hydrocarbon gas oil or residual fuel oil, in proportions of not more than 7 parts oil to 1 part soot, in a first space and transferring a part of the mixture to a second space where, after further stirring, the soot aggregates with oil are separated.  The soot suspension may be obtained from the gaseous products of incomplete combustion of hydrocarbons or their mixtures and may contain not more than 40 g. soot/1.  The average total residence time of water in the two spaces may be 1-25 min.  The apparatus of Fig. 1 comprises two mixers 1 and 2, the propeller blades of which may be 1/6 -\ba3/5 the diameter of the mixer and which are connected in series. Supply lines 3 for the soot suspension and 4 for the oil open into line 5 which is connected to the bottom of mixer 1 which is provided with overflow 6 opening into mixer 2 through a centrally arranged pipe section 7.  Discharge 8 for the water and the soot aggregates has a filtering element 9 which separates the soot.  The water is collected in tank 10 and the aggregates pass to a collecting space (not shown) via funnel 11. Agitators 12 and 13, arranged in mixers 1 and 2, are equal in size, may also have the same speed and may be driven by a common electric motor.  The soot obtained may be used as a fuel, e.g. in cyclone burners, or may be purified by evaporation of the oil.  Specification 741,135 is referred to.

Abstract: 1,045,557. Mineral insulated cables. BRITISH INSULATED CALLENDER'S CABLES Ltd. Sept. 24. 1965 [Sept. 25, 1964], No. 39223/64. Heading H1A. [Also in Division H2] Identification of the conductors of electric cables insulated by compacted mineral powders is achieved by cutting in them longitudinal grooves, so shaped that insulation remains in them when the sheath is stripped and the conductors bared. Ingress of moisture into the cable through such a groove acting as a wick may be prevented by impregnating the insulation in the groove with a moisture-resistant material. For example if a sealing pot is applied to the end of the cable and filled with a sealing compound containing an oleaginous liquid this migrates from the compound into the powdered mineral insulation in the groove in large enough amounts to make it a barrier to moisture. Alternatively the insulation may be removed from the groove or the groove eliminated locally at a point to be covered by the sealing box before it is applied.
