Title: Improvements in or relating to method of utilizing metallic sodium for the concurrent manufacture of sodium cyanate and fatty alcohols
IPC: C01C3/20
Filed: 1951-03-22
Abstract: Fatty alcohols and sodium cyanate are simultaneously manufactured by reacting metallic sodium with a fatty ester, especially fatty triglycerides, in the presence of a reducing alcohol to produce sodium alcoholates which are then reacted with urea preferably at 110 DEG  to 200 DEG  C. to produce alcohols and sodium cyanate which is precipitated.  The fatty esters are the reaction products of aliphatic carboxylic acids containing 8 to 24 carbon atoms with mono- or polyhydric alcohols and are exemplified by methyl oleate, ethyl stearate, butyl laurate, methyl behenate, beef tallow, cottonseed, coconut and sperm oils.  The free fatty acid content, if any, may be esterified to avoid the production of sodium soaps.  The reducing alcohol, which must boil at a lower temperature than the lowest alcohol which is desired to produce, is one which reacts with sodium to furnish hydrogen which reduces the fatty ester to a fatty alcohol, examples being secondary or tertiary butyl, methylamyl and tertiary amyl alcohols and cyclohexanol.  Xylene and toluene may be employed as inert diluents and may be removed by distillation before the reaction with urea.  The reaction may take place in a nitrogen atmosphere. The precipitated sodium cyanate is separated and washed and the alcohols fractionally distilled, glycerine, if present, being first removed by washing the alcoholic mixture with water.ALSO:In the concurrent manufacture of sodium cyanate (which may then be conventionally reduced to cyanide) and fatty alcohols, metallic sodium is reacted with a fatty ester in the presence of a reducing alcohol to produce sodium alcoholates which are then reacted, preferably at 110 to 200 DEG C, with urea to produce alcohols and sodium cyanate which is precipitated.  The fatty esters are the reaction products of aliphatic carboxylic acids containing 8 to 24 carbon atoms with mono- or polyhydric alcohols and are exemplified by methyl oleate, ethyl stearate, butyl laurate, methyl behenate, beef tallow and cottonseed, coconut and sperm oil.

Title: Improvements in photographic developers
IPC: G03C7/413
Filed: 1953-03-13
Abstract: 720,812. Photographic developers. KODAK, Ltd. March 13, 1953 [March 14, 1952], No. 7057/53. Class 98 (2). A photographic developing solution comprises an alkaline solution of a silver halide developing agent (e.g. p-phenylenediamine, diethyl - p - phenylenediamine, 2 - amino -5 - diethylaminotoluene, hydroquinone, or N - methyl - p - aminophenol), an alkali metal sulphite (e.g. sodium or potassium sulphite or potassium bisulphite), and an 8 - hydroxy - quinoline - 5 - sulphonic acid (e.g. 8 - hydroxy - quinoline - 5 - sulphonic acid itself) or its 7 - chloro-, 7 - bromo -, or 6 - methyl - deriva - ' tives). The alkali may be sodium carbonate, hydroxide, or metaborate, and the developer may contain a primary aliphatic amine such as ethylenediamine, guanidine, or ethanolamine, or morpholine. The use of triglycin is referred to. The 8-hydroxyquinoline-5-sulphonic acid may be incorporated in the emulsion or in an overcoating, intermediate, or backing layer.

Title: Improvements relating to Conveying Systems
IPC: A24C5/352
Filed: 1966-02-17
Abstract: 1,170,054. Endless conveyers. MOLINS MACHINE CO. Ltd., and D. W. MOLINS. 15 Feb., 1967 [17 Feb., 1966], No. 7095/66. Heading B8A. [Also in Division G1] A conveyer is adapted automatically to pick up a full container 2a of cigarettes and deposit an empty container 2b at a container loading station 13-18 and is adapted at a container unloading station 19-21 to deposit a full container and pick up an empty container. Detector mechanisms comprising a strain gauge (not shown) at 87, 97 and 107, operate only in response to the passing of full containers. Each mechanism generates a signal depending on the weight of a tray. Similar mechanisms 27, 37, 47, 57, 67, 77 operate only in response to the passing of empty containers. The detectors may also be operative in response to a visual code in the form of black bars 38 painted on a white disc. This ensures that the output of particular cigarette-making machines 13-18 is delivered to selected ones of cigarette packing machines 19-21. Until a detector mechanism is activated by a container, the latter will continue circulating the conveyer. When, for example, a carrier 12 of the conveyer supporting an empty container approaching the loading station 13 activates detector mechanism 27, a deflectable portion 29 of a guide rail 28 is moved to the position shown in dot-dash lines (Figs. 2 and 5). This causes the carrier 12 to swing about a pivot 31 of the conveyer carrier and causes the tray to be engaged with a stop on a table 33 of the loading station 13. During the swinging-in movement, the tray is also turned through 180 degrees (about an approximately vertical axis) due to the action of a twisted camming portion 32 of a conveyer hanger as it engages a falling part of the rail 28. This reversal is necessary because a container which is to be picked up at a station, has to be engaged on the leading prong of a carrier 12, while the latter has to be turned before arrival at the destination station, to a trailing position, to permit disengagement. Instead of having deflectable rail portions 29, the detector mechanisms when actuated at a station, may cause a platform (40) (Fig. 6, not shown) to be extended and thereby to result in loading or unloading. In a further modification (Fig. 7, not shown), a cable 45 is actuated by a detector to lift or lower a hanger 12 to effect a picking up, or setting down, respectively, of a container.

Abstract: 1,115,961. Valves; fluid pressure brakes. RENAK-WERKE VEB. 21 Feb., 1966, No. 7486/66. Headings F2F and F2V. In a valve for controlling the pressure applied to a brake cylinder, fluid flows to the cylinder via an inlet 8, valve 6, 10, chamber 16 and outlet 3. When the pressure reaches a predetermined value, the assembly comprising valve member 10 and piston 9 is moved to the right against spring 17 to seat the valve member. When the inlet pressure falls below the outlet pressure, return flow takes place via bore 15, check valve 13, 14 and groove 11. The check valve is defined by the piston seal. The pressure at which the valve closes may be adjusted by moving a piston 21 to the left to abut the seat 18 of spring 17, thereby allowing a spring 20 to act together with spring 17 on the piston 9. The piston 21 may be moved by a wedge and lever arrangement. In a modification, the check valve comprises the seal 13 but the return passage is located in housing 1. The seal may comprise two separate parts, e.g. a ring for sealing the piston 9 and a rubber band over port 14.

Title: Improvements in or relating to vapour electric discharge devices
IPC: H01J13/02
Filed: 1939-03-10
Abstract: 526,197. Metal-vapour apparatus. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. March 10, 1939, No. 7751. Convention date March 25, 1938. [Class 39 (i)] A vapour discharge device has a container with the major part of its wall area of non- translucent material, a vaporizable cathode other than of mercury and of a material solid at room temperature and means for keeping the portion of the container which houses the cathode within a temperature range bounded by the cathode melting point and the temperature at which the vapour pressure generated by the cathode would cause back fires. The cathode may be of bismuth, lead, cadmium, lithium, sodium, caesium, rubidium or gallium, or of alloys of these. In the form shown, the metal cathode container 13 has a curved top 14 attached by an insulator 15 to the anode lead-in member 16 from which the make-alive electrode 20 is supported by an insulator 22 and the metal closure 21 of the container. The anode 17 is screened from dropping condensate by a skirt 23, mounted on an insulating layer 24, and is secured to the lead-in 16 by two screwed joints 19, 18. The outer casing 25 is preferably of heat-insulating material and the bottom 26 may be of metal to give contact to the cathode. Temperatures are controlled by a heater 27, connected to the supply 29 through a thermostatic switch 28 and a fan 35, controlled by a thermostatic switch 34 which also controls a damper at a port 32. A thermostatic switch 30 is also connected in series with the electrode 20. If, for example, a bismuth cathode with a melting point of about 269‹C is used, the switch 28 is closed to bring the device above this temperature and switch 30 closes at about 300‹C to start the device. At 325‹C the switch 28 interrupts the heater circuit and recloses if the temperature falls to 300‹C. If, however, the temperature reaches 350‹C the switch 34 closes, thereby opening the port 32 and starting the cooling fan 35. The switch 34 may close the port and shut off the fan at 325 ‹C.
