Patent GB-579564-A (GB)
Title: Improved apparatus for the automatic regulation of the temperature in buildings
IPC: F24D19/10
Filed: 1943-01-26
Abstract: 579,564. Correspondence control systems. LANDIS & GYR. SOC. ANON. Jan. 26, 1943. No. 1302. Convention date, Jan. 30, 1942. [Class 40 (i)] [Also in Group XXXV] The heating system of a building is divided into two circuits I, II heating portions thereof respectively, and controlled by two external thermostats TR, TRb related in position to the respective portions. To minimize heat losses the control is arranged so that the thermostat calling for most heat controls, for example. through the action of a thermostat applied to the flow pipe of its related heating circuit, the supply of heat to both circuits while the remaining thermostat controls by similar means the heating fluid in its related heating circuit by regulating the mixture of flow and return fluid. The external thermostats TR, TRb shown are of the kind comprising a bimetal switch and heating resistance in an enclosure simulating the heat losses in the building, and have back contacts which produce electrical impulses, the duration of which in relation to the duration of the intervals increases with increased cooling of the thermostat. These impulses are transmitted to auxiliary heating windings on the related applied thermostats TA. TAb, thereby controlling their action in response to the temperature of the fluid. They are also transmitted through relay J, JI to a differential thermal relay TU which controls the action according to the invention by de-energizing a relay U when the thermostat TR calls for more heat and energizing it when the thermostat TRb makes the greatest demand. In the latter case, a contact U1 energizes the motor of a mixing valve Vb to open fully the flow pipe of circuit I and to close the admixture inlet thereof and a contact U2 energizes a relay UR to place under the control of applied thermostat TA, controlled by external thermostat TR, the motor of valve V, which controls the mixture in the flow pipe of circuit II. The contact U1 de-energizes a relay. UR1 whereby the motor of a valve Vb, regulating the supply of heat to a heat exchanger which supplies heat to both circuits I, II, is placed under the control of thermostat TAb controlled by external thermostat TRb. A corresponding change over occurs when the relay is deenergized by the thermostat TR calling for more heat. The system described includes a time switch S whereby reduced operation may be obtained at night. A contact on the time switch makes the night rate effective throughout the week-end. A switch NV renders the system inoperative and causes the heat supply valve Vp to be closed. Similar action occurs when the main switch H is opened. The invention is not limited to the type of heating system shown, nor to the kind of differential relay or thermostats employed or to motor actuation of the controls.

Patent GB-689390-A (GB)
Title: Improvements in the preparation of nucleosides
IPC: C07H1/00
Filed: 1950-01-23
Abstract: Nucleosides are prepared by hydrolysing nucleic acid in aqueous solution at pH 6.5-8 in the presence of an agent capable of combining with the nascent phosphoric acid and maintaining the pH within this range during the hydrolysis; the nucleosides are then p  separated and worked up as usual.  The "agent" may be a metal compound sparingly soluble in water but soluble in acids, which forms an insoluble phosphate, e.g. magnesium, calcium, barium, lead or zinc hydroxide, or magnesium, calcium or barium carbonate. Thus the nucleic acid solution is boiled with 10-20 per cent excess of lead or zinc hydroxide (based on P2O5), preferably under increased pressure, filtered and left to crystallize.  When using zinc hydroxide the products are zinc salts of nucleotides which are further hydrolysed by water at 140-150 DEG  C.  Further nucleosides are obtained from the mother-liquor after adding alcohol to precipitate the albumen; preferably methanol is used, to give an alcohol content of 70-80 per cent in the solution.  The "agent" may also be an inorganic or organic buffer (e.g. sodium citrate), a water-soluble acid amide (e.g. formamide, methylformamide or dimethylformamide) or a water-soluble cyclic ether (e.g. dioxane, tetrahydrofurane). When using an amide or an ether alkali is added to bring the pH within the desired range.  Examples are given of various methods of carrying out the process.  Specified products are guanosine and adenosine, which may be isolated as picrate.  Pyrimidine nucleosides are also obtained.

Patent GB-538634-A (GB)
Title: Improvements in or relating to the dewaxing of mineral oil
IPC: C10G73/02
Filed: 1940-02-01
Abstract: 538,634. Dewaxing mineral oil. TEXACO DEVELOPMENT CORPORATION. Feb. 1, 1940. No. 2014. Convention date, Feb. 11, 1939. [Class 91] [Also in Group I] Mineral oil is de-waxed by a process of continuously filtering a chilled wax-oil mixture containing wax in suspension which comprises continuously submerging a rotating filtering surface in the chilled mixture, and washing, drying and removing the filter cake formed thereon, characterized by controlling the cake formation by improving a back pressure within the filtering element for at least a substantial portion of the time that the filter element is submerged. The back pressure is regulated to be sufficient to substantially offset the hydrostatic pressure on the exterior of the filter surface due to its submergence in the chilled mixture: The back pressure may be maintained by injecting gas under pressure to the interior of the submerged filter surface. In Fig. 1 a horizontal drum 3 running on trunnion 4 and divided into a number of segments 5 is supported within the bowl 1. Material to be filtered is introduced through pipe 2, and the liquid portion thereof is drawn through the filter surface into each segment and from there through tubes 6 to the filter valve on the trunnion from which it is discharged through pipes 7, 8 and 9. Upon emergence from the liquid the filter cake is washed by sprays from 11 and 12, dried by flue gases from line 14, loosened from the filter surface by pressure from blowback line 15 and collected into trough 17 by knife 16. The positive pressure which is maintained in the segments until they have attained a pre-determined depth in the chilled mixture is obtained by injecting gas through line 18.. The gas passes into a number of valved pipes and then into the segments which are in the position in which it is desired there should be a positive pressure. The pressure is varied by the valves on the pipes leading from line 18 so that the pressure in any particular segment is approximately equivalent to the external hydrostatic pressure. The regulation of the pressure is carried out by means of a filter valve which contains a number of openings at specified points and which presses in a gastight manner against corresponding holes in the rotating trunnion 4. After a segment has passed the point at which it is no longer desired to stop the formation of the filter cake, the hole in the trunnion corresponding to its exit 6 comes opposite to a hole in the filter valve corresponding to reduced pressure and filtration takes place. The reduced pressure is maintained until the washing and drying are completed and it is desired to loosen the filter cake from the filter cloth, when a positive pressure is again applied.
