Title: Dibenzyloxyphosphoryl creatinine and a process for the preparation of phosphocreatine and/or phosphocreatinine therefrom
Inventor: ANATOL JESUS
IPC: C07F9/22
Filed: 1959-09-28
Abstract: The invention comprises dibenzyl-oxyphosphoryl creatinine having the formula:-  <FORM:0937931/IV(a)/1> It may be obtained by first preparing the N-dibenzyl-oxy-phosphorylated derivative of S-methyl isothiourea of the formula:-  <FORM:0937931/IV(a)/2> by the action of dibenzyl phosphite in solution in carbon tetrachloride on S-methylisothiouronium sulphate in the presence of caustic soda, reacting the isothiourea compound in ethanol with red oxide of mercury in the presence of sodium carbonate to form the sodium derivative of dibenzyloxyphosphoryl cyanamide of the formula:- <FORM:0937931/IV(a)/3> reacting the latter in alcoholic medium with the hydrochloride of ethyl sarcosinate to form dibenzyloxy-phosphoryl ethyl creatinate, hydrolysing the latter in aqueous alcoholic medium, to form the sodium salt of dibenzyloxy phosphoryl creatine and finally acidifying the latter with a weak acid, e.g. acetic acid. The dibenzyloxyphosphoryl creatinine may be converted to the disodium salt of phosphocreatinine by reacting it with hydrogen in aqueous alcoholic medium in the presence of a hydrogenation catalyst, e.g. palladium black, and caustic soda at a temperature below 30 DEG C. and the product on further treatment with caustic soda at above 30 DEG C. is converted to the disodium salt of phosphocreatine of the formula:-  <FORM:0937931/IV(a)/4> The phosphocreatine may also be obtained as its disodium salt by reacting dibenzyloxyphosphoryl creatinine in aqueous alcoholic medium with hydrogen in the presence of a hydrogenation catalyst and caustic soda at a temperature above 30 DEG C.  The sodium salt of dibenzyloxyphosphoryl creatine referred to above can also be subjected to hydrogenolysis in the presence of palladium black and caustic soda to form the disodium salt of phosphocreatine.

Abstract: 426,573. Refining metals and alloys. AMERICAN SMELTING & REFINING CO., 120, Broadway, New York, U.S.A. Nov. 24, 1933, No. 32924. Convention date, Dec. 1, 1932. [Class 82 (i)] Metals and alloys are refined by liquefying the mass and volatilizing the lower boiling constituent in a vacuum in that range of temperature which is below the turning point above which temperature increases nearly linearly with pressure. The metal or alloy is placed in a cast iron refining kettle 10 and, after melting, a bell 11, provided with inner and outer walls 12, 13, between which are cooling tubes 14, is placed in the kettle. A vacuum is produced in the bell by a suction pump attached to a U-tube 18. A pump 16 forces metal from the body of the bath against a plate 17 to increase volatilization. The metal which evaporates condenses on the walls of the bell and collects in a trough 21. Molten metal or high boiling point oils may fill the space between the walls 12, 13. The interior of the bell may be coated protectively. As examples of separations accomplished by the process arsenic is removed from tin and lead, cadmium, sodium and zinc are removed from lead and sodium and magnesium from tin.

Title: Environmental responsive apparatus
IPC: H02J9/02
Filed: 1963-08-21
Abstract: 1,012,068. Temperature alarms. MAINTENANCE CO. Inc. Aug. 21, 1963 [Sept. 10, 1962], No. 33107/63. Heading G4N. [Also in Division G1] The invention relates to control apparatus responsive to changes in its environment such as in ambient light or temperature changes due to a fire, and consists of a rechargeable battery having across it a voltage divider which responds to the said changes to vary the voltage at its tap, and switching means in series with a device to be controlled, the switching means and the device being connected across the battery, the tap being connected to the switching means to activate it and allow current to flow through the device upon the occurrence of an environmental change. The figure shows an emergency lighting circuit for lighting an emergency lamp 36 in the event of failure of the local lighting or power and includes a battery 26 which is continuously trickle charged by a transformer acting through a half-wave rectifier 30. When the local lighting is on the resistance of a cadmium sulphide photo-resistor 44 is low compared with a resistor 42 so that the voltage drop across the photo-resistor 44 is also low. When the local lighting is absent the resistance of the photo-resistor rises and the voltage at the tap 46 becomes sufficient to cause a silicon controlled rectifier 40 to fire and thus light the emergency lamp 36. Capacitors 38 and 50 prevent triggering of the rectifier 40 due to transient conditions. In a further embodiment (Fig. 2, not shown), the silicon controlled rectifier 40 is used to trigger a high current silicon controlled rectifier which is connected in series with a heavy lighting load. The photo-sensitive resistor 44 may be replaced by temperature-sensitive resistor to detect fires and the silicon controlled rectifier in this case operates an aural fire alarm or fire control equipment such as sprinklers. The temperature-sensitive resistor and the resistor 42 may be interchanged to enable the apparatus to be used to monitor cold storage rooms to prevent freeze damage to food products. The photo-resistor could be placed in a smoke collecting chamber and normally illuminated by a source across the chamber. In the presence of dense smoke the light falling on the resistor would be reduced sufficiently to actuate the circuit. To sense humidity the photoresistor could be replaced by a suitable moisturesensitive device.

Title: Viewing screens for use in optical systems employing polarized light
IPC: F21S8/10
Filed: 1937-11-30
Abstract: 490,888. Anti - dazzle screens for vehicles. LAND, E. H. Nov. 30, 1937, No. 33120. [Class 103 (ii)] [Also in Group XX] Relates to anti-glare polarizing-screens, particularly for use on vehicles, it being assumed that all beams from vehicle headlights are polarized. The purpose of the screen according to the invention is to eliminate glare both from approaching lights at night and also from reflection by road &c. surfaces in daylight. For this purpose the screen comprises an element which plane polarizes the light traversing it, and a phase-changing element adapted to alter the character or direction of vibration of a polarized beam, the screen being so mounted that either element can be interposed between a light source and the other element. When the light from headlamps is plane polarized it is assumed that the plane of polarization is at 45‹ to the vertical; it is also assumed that the light reflected from road &c. surfaces is so polarized that its vibrations are horizontal. In this case the screen consists of a polarizing element 15 having its axis 17 vertical, and a half-wave plate 16 having its axis 18 at 22À5‹ to the vertical. The elements 15, 16, which may be mounted on glass &c. plates 14 are secured in a frame 12 which is mounted on pivots 13 in brackets 10 so that either of the elements may be disposed nearer the eyes. If it is desired to impede polarized rays from oncoming lamps, the plane of vibration of which is indicated by the arrow 20, the screen is positioned with the element 16 facing the lamps. The effect of the plate 16 is then to rotate the plane of polarization until the vibrations are horizontal so that the light is not transmitted by the element 15. For use in the daytime, the screen is turned about the pivots 13 to bring the half-wave plate 16 to the rear of the element 15, in which position the plate is ineffective. Instead of mounting the elements 15, 16 together in a single frame as shown, they may be mounted in separate frames pivotally connected together so that the plate 16 may be turned into, or out of, position in front of the element 15. For use with lamps emitting circularly polarized light, the screen consists of a plane polarizing element and a quarter-wave plate having its axis at 45‹ to that of the polarizing element. U.S.A. Specification 2,031,045 is referred to.

The lubricant is distributed from the sump to various points by means of wicks 43 extending upwardly through a tube 44 to a distributing head 45 provided with wickretaining tubes 46. The oil collecting cup 56 is provided with a felt disc 69 or alternatively, or in addition, a restriction may be formed in a tube below the cup so that the flow of lubricant is not fast enough to cause lubricant to flow along the part 48 of the siphon tube back to the sump 42. This part 48 preferably is slightly inclined downwardly towards the vertical leg 58 of the siphon. In the operation of the system the siphon action is started by means of the lubricant collected by the cup 56. The short leg of the siphon 47 may be provided with a restriction or with a cap of felt over the inlet end to reduce the rate of siphon action and keep the siphon filled even though the level of lubricant in the sump 42 may fall below the lower end of the inlet of the leg, 47. The needle head is provided with a transparent plug 73 and the reservoir 38 adjoining the reservoir 37 is provided with a transparent plug 78 with the aid of which the level of oil in the sump and in the reservoir may be noted.
