Title: Improvements in or relating to the de-acidifying of ammonia water
IPC: C01C1/10
Filed: 1957-03-25
Abstract: Aqueous ammonia containing hydrogen sulphide and hydrogen cyanide, e.g. from a coking plant, is treated at a temperature of 50-110 DEG C., preferably 60-90 DEG C., with oxygen as such or in the form of air in order to convert the hydrogen cyanide at least partially to ammonia thiocyanate and thereby prevent or diminish corrosion during subsequent deacidification of the aqueous ammonia.  The reaction may take place in a relatively small tower, e.g. 2.5 m. high, packed for example with saddles or Raschig rings, at atmospheric or super-atmospheric pressure.  The aqueous ammonia may be passed as a continuous column through a tube or the like instead of through a washing tower.  Co-current or counter-current flow may be employed. The stoichiometric amount of air is preferably employed.  An excess of oxygen tends to produce thiosulphate.  If a deficit of oxygen is employed, the hydrocyanic acid content should not be reduced below the "threshold" value, which is about 0.2 gm. of hydrocyanic acid per litre of solution using deacidifying apparatus of V4A steel. Experiments at various pressures, temperatures, air/solution ratios, HCN and NH3 content and percentage conversion are specified in a Table and a separate Example.  The velocity of the oxygencontaining gas is preferably kept at such a value that substantially no volatile substances are entrained in the effluent gas.  Ammonia may be removed from the effluent gas by passing the gas into a sulphuric acid saturator or into the middle section of a deacidifier.  In a cyclic process aqueous ammonia may be passed successively through a scrubber for removing hydrogen sulphide from coke oven gas, a tower for treatment with oxygencontaining gas, and a deacidifier, and back to the hydrogen sulphide scrubber, the effluent from the hydrogen sulphide scrubber being heated by heat exchange with the effluent from the deacidifier before the oxygen treatment.  Solution may be bled off before the oxygen-treatment step and replaced by ammonia solution.

Title: Removal of boron from carbonaceous materials
Inventor: CAWLEY CHARLES MILLS
IPC: C01B31/00
Filed: 1950-04-20
Abstract: Boron is removed from carbonaceous material by heating the material with an alcohol having a boiling point lower than that of water so as to distil off the alcohol and boron.  Acetic, perchloric, sulphuric, or hydrochloric acid may be present in an amount up to normal acidity.  Examples describe the treatment of coal tar and finely ground coal by heating one or more times with methyl alcohol. Reference is also made to the treatment of coal pitch, petroleum oil, and coke.  The carbonaceous material may be converted to carbon having a low boron content for use in the atomic energy field or for spectrographic carbon.  The process may be used for measuring the proportion of total boron present as borate in the carbonaceous material.  The Provisional Specification refers also to the use of phosphoric acid in place of the other acids.

Abstract: 1,025,224. Control of D.C. motors. YALE & TOWNE Inc. March 13, 1963 [March 29, 1962], No. 9901/63. Heading H2J. A battery-operated truck is operated at a first speed by connecting field windings 11, 12, resistor 15, and armature 10 in series across batteries 13, 14, which are in parallel with each other. A slightly higher speed is obtained by short-circuiting resistor 15. A third higher speed is afforded by re-inserting resistor 15 and connecting the batteries in series, rectifiers 18, 19 preventing short-circuiting of the batteries during the change-over. The resistor 15 is again short-circuited. A fifth speed is obtained by re-inserting the resistor 15, short-circuiting field winding 11, and then connecting the field windings in parallel with each other. For operation at a sixth speed, the resistor 15 is again short-circuited. The direction of operation of the traction motor may be reversed, by reversing the field excitation. The various contacts in the control circuit may be operated from a master controller.

Title: Improvements in harness or the like for airmen
IPC: B64D25/06
Filed: 1929-03-28
Abstract: 328,406. Potter, J. March 28, 1929. Body harness.-Relates to aviators' harness which in normal use is attached at the leg, thigh and shoulder and to a fixed point in the aircraft such as the pilot's seat and which for emergency use is also attached to a parachute, and consists in a construction for enabling a quick release of an upper anchoring cable at the shoulder or upper part of the harness, a quick release for a lower anchoring cable at, for example, the leg of wearer, and in addition for enabling a slacking of the connection at the upper or lower part for providing additional freedom at any time. The quick release devices are operated simultaneously by one hand or by operating a single control member. The slackening of the harness connection enables the wearer to attend, for example, to a gun, compass or other instrument. In one form of the invention, shown in Fig. 1, a quick release coupling or slip device 10 shown in detail in Fig. 4 maintains connection between two cables 9 by being restrained in a tube 11. One of the cables passes at one end round a guide pulley 13 to a position in front of the pilot. An anchor cable 6 is attached to and runs freely through a ring 8 on one of the cables 9. The other cable 9 terminates at a spring catch 15 which is capable of sliding along a rail 16 and engage in any one of a series of recesses or holes. When this catch is pushed forwardly a short distance only freedom of movement is allowed to the pilot. If the catch is pushed further it allows of disengagement of the slip device 10 and also engagement of a tripping device 29 connected by a Bowden cable to a spring safety-pin 26, Fig. 3, which pin holds in position a coupling 25 engaging two straps 22 under the pilot's seat. The straps 22 terminate in snap hooks 21 engaging rings 4 attached to the harness near the thigh of the wearer. Corresponding rings and snap hooks engage rings 5 on the shoulder straps. The rings and snap hooks enable the wearer to free himself after a flight. In a modification, release of the upper and lower anchoring elements is controlled by separate levers' mounted coaxially. Release of the anchoring cables may also be obtained by Bowden control from a single lever. The upper anchor cable may be released by screw and nut gear.
