Abstract: 962,551. Automatic temperature control. WOODS OF COLCHESTER Ltd. Feb. 8, 1961 [March 11, 1960], No. 8702/60. Heading G3R. [Also in Division H2] In a ventilation system for a broiler house electric motors 11, 12, 13 driving ventilation fans are connected in parallel and energized from an alternating current supply 14 through an autotransformer 19 and thermostats 16, 17, 18. As the temperature in the broiler house increases from a low value the thermostat 16 operates to connect the motors to the supply through a low voltage tapping 21. With further increase in temperature the thermostat 17 operates connecting the motors to a tapping 24 to cause an increase in the voltage applied to the motor and a consequent increase in the speed of the ventilating fan. When thermostat 18 is actuated the motors are directly connected to the supply and the ventilating fans run at maximum speed. A motor can be manually disconnected from the system by a switch 28. It is stated that the voltage applied to motors supplied from a direct current supply can be similarly controlled through a tapped resistor and motor supplied from a thru-phase supply can be controlled by having connections and contacts appropriate to each phase.

Title: Concentration of uranium isotopes by molecular distillation of uranium poly alkoxides
IPC: B01D59/04
Filed: 1946-03-20
Abstract: Uranium penta-ethoxide or penta-n-propoxide, whose uranium includes at least the isotopes of masses 235 and 238, is treated to segregate a fraction concentrated with reference to U235 by subjecting the alkoxides to molecular fractional distillation p  whereby are obtained a distillate concentrated with reference to U235 and a residue concentrated with reference to U238.  Any alkoxide containing U234 is concentrated in the distillate.  The distillation may be effected under pressures of 10-7-10-3 mm. Hg. at temperatures from 85 DEG -210 DEG C. The surfaces of the still contacting the alkoxide should preferably be free from Zn, Al and Sn and suitably are made of glass, nickel, stainless steel or "Monel" or "Nichrome" (Registered Trade Marks).  A suitable form of still is described (see Group III). The still described in Specification 822,001 may also be used. Examples are given.  The alkoxides may be prepared as described in Specification 799,948.  The Specification as open to inspection under Section 91 states that other normally liquid uranium poly alkoxides may be treated likewise, such as the hexaethoxide, hexa-n-propoxide and mixed alkoxides, for example the tetra-n-propoxide-mono ethoxide. This subjectmatter does not appear in the Specification as accepted.ALSO:<PICT:0863259/III/1> A molecular still comprises a still pot 4, a reflux column 5 containing a plurality of separate distillation units 17, heaters 7 and 8, a cooler 9 serving to cool the upper parts of the column and still pot and a condenser 6 which completely condenses vapours arising from the column.  In use, vapours from the still condense and collect in cup 14 of distillation unit A, wherein the condensate redistils and then condenses and collects in the cup of unit B, while condensate from unit B flows into unit A.  In this manner distillate passes up the column and condensate flows down, building up to an equilibrium wherein the liquid in the cup of unit Z becomes of substantially constant composition and may be drawn off via pipe 19.  The still surfaces may be composed of glass, nickel, stainless steel or "Monel" or "Nichrome" (Registered Trade Marks).  The still is employed in the fractional distillation of uranium alkoxides to concentrate the alkoxide containing U235 in the distillate (see Group IV(b)). Specification 822,001 is referred to.

A process for preparing a reverse osmosis membrane comprises preparing a dope containing a solvent, casting a film from the dope on a support, forming a skin on the film's free surface by allowing part of the solvent to evaporate from the free surface, and immersing the film on its support in a liquid so that the liquid advances over the free surface at a rate lying in the range of from 40 mm./sec. to 500 mm./sec. The process may further include heating the film while it is immersed in a liquid. The liquid's advance rate preferably lies within the range of from 50 mm./sec. to 100 mm./sec., and may throughout the immersion period vary by at most 10%, and preferably 3%, from the mean value. The advance rate may be substantially constant. The film may be cast on a support plate 1 which may be inclined to the horizontal and which may be immersed by fluidoperated jack 5 in liquid 4 to cause the liquid to flow over the free, inclined, film surface.
