Title: Improvements in or relating to apparatus for the production of heavy water
IPC: B01D59/32
Filed: 1957-07-03
Abstract: <PICT:0869414/III/1> Apparatus for thee production of heavy water comprises a dual-temperature H2-H2O D-exchange plant for producing a D-enriched product, which comprises a combination of a single exchange tower 12 consisting of alternate water-water vapour countercurrent contacting sections 13 and low temperature, e.g. 90 DEG C. vapour phase H2-H2O D-exchange catalyst beds 14, and a plurality of high temperature, e.g. 600 DEG C. H2-steam D-exchange catalyst beds 16 and H2O-steam countercurrent contacting columns 15 so arranged that water passes through the contacting columns, while H2 and water vapour pass alternately through the contacting columns and the catalyst beds. Water enters the "Trail" column 12 at 11 and flows down countercurrent to H2 and steam The D-enriched water flows through contacting columns 15, 15a, 15b and is withdrawn at 18b and transfers D to the H2 and steam which passes in countercurrent up columns 15 and catalyst beds 16 with associated heat exchangers 17. The D-poor H2 from the top of the "Trail" tower is recycled through 19. D-enriched H2 may be withdrawn through 20 and condenser 21, from which water is returned through 22, to distillation apparatus 23 as in Specification 869,413, whence the D-rich fraction at 27 is converted to heavy water. The D-poor fraction passes through rehumidifier 24, through which water is circulated by pump 26, catalyst beds 16a, 16b with associated heat exchangers 17a, 17b, and contacting columns 15a, 15b. Alternatively, the water may pass to waste at 18, and fresh water be supplied to columns 15a, 15b at 11a, 11b. In a simpler apparatus (Fig. 1, not shown) the distillation is eliminated, and D-enriched H2 or H2O may be withdrawn below the "Trail" column.

Patent ES-367722-A1 (ES)
Title: Electrothermal motor starting apparatus
IPC: H02P1/42
Filed: 1969-05-27
Abstract: The starting winding of a motor is disconnected by a bi-metallic disc switch when a thermistor reaches a threshold temperature. The thermistor is connected across the main winding of the motor and the series combination of the starting winding and the switch, and has a transition temperature above which its resistance increases abruptly. In another arrangement, the thermistor is connected across the starting winding so that it remains energized by induced voltage after the supply voltage is removed from the starting winding. In a further embodiment, the starting winding 1 is energized through triac 15 when the motor is switched on. Heat regenerated in thermistor 23 is communicated to thermistor 19 whose resistance increases to de-energize the triac. If the motor fails to start, the thermistors are permitted to cool and the triac is rendered conductive for a new starting attempt.

Title: Method of making food containers
IPC: B23K11/06
Filed: 1971-04-05
Abstract: A method of making tin lines drums and other large containers adapted for use in storing and shipping food products.

Patent ES-450168-A1 (ES)
Title: Centrifuge separation and washing device and method
IPC: B01D21/26
Filed: 1976-07-26
Abstract: A centrifuge device and method are provided for separating and/or washing finely-divided solid particulate material suspended in a liquid. The invention is especially useful in so treating blood. The centrifuge forms a dense suspension of blood cells in a plurality of blood cells receiving means evenly spaced about the periphery of a rotatable enclosure. The receiving means have converging walls which at their juncture form a locus of maximum centrifugal force. Wash liquid is passed through the dense suspension of blood cells counter to the direction of the centrifugal force by entry into the blood cell receiving means at the locus of maximum centrifugal force. Independent conduits connect the locus of maximum centrifugal force through an injector to a supply for the wash liquid and, after fully resuspending the blood cells in a suitable resuspending liquid, the resuspended cells exit from the centrifuge via the independent conduits and injector, which have also therefore been washed by the wash liquid. Thus recontamination is avoided. A unitary disposable structure including the enclosure, blood cell receiving means, conduits and injector is also provided.
