Patent GB-855301-A (GB)
Title: Attrition resistant adsorbents
IPC: B01J20/18
Filed: 1957-04-11
Abstract: <PICT:0855301/III/1> Zeolitic molecular sieve crystals, prepared as described below, are treated with an aqueous sodium silicate solution containing 3 to 50% SiO2 based on the dry weight of the molecular sieve and the treated sieve crystals are thereafter dried and activated.  The molecular sieves are prepared by mixing sodium aluminate and sodium silicate solutions in proportions such that the silica/alumina ratio of the mixture is from 0.5 to 1 to 3 to 1, at a temperature within the range of 160 to 215 DEG F., the sodium silicate employed having a Na2O/SiO2 ratio of at least 0.8/1 and the sodium aluminate having a ratio of Na2O/Al2O3 in the range of 1/1 to 3/1 .  The sodium zeolite so produced may be treated with a metallic salt solution to convert the zeolite to, for example the calcium, copper, lithium, potassium, magnesium, barium, strontium, zinc, cadmium boron or aluminum form, either before or after compositing with the sodium silicate.  As shown in the drawing, a sodium metasilicate of concentration 30 to 300 grams SiO2 per litre and sodium aluminate of concentration 40 to 400 grams Al2O3 per litre in vessels 2 and 4 respectively are mixed in vessel 10 preferably to give a silica/alumina ratio of 2/1 .  The zeolitic sieve precipitates, preferably in the presence of seed crystals and is passed to a washing zone 16 and may be immediately treated with a calcium solution to form the corresponding calcium-sodium alumino-silicate. Preferably however the washed zeolitic sieve is withdrawn as a filter cake and slurried in a mixer 22 with a sodium silicate solution and the slurry so formed, may be spray dried. The dry products may be passed to an ion exchange zone 26 where they may be treated with calcium chloride solution, for example in a concentration of 2 to 25%.  Such treatment converts the sodium sieve to the calcium form and also converts the sodium silicate coating to calcium silicate.  The temperature is thereafter raised to 200 DEG F. and the sieve is withdrawn and washed and activated at 400 to 1000 DEG F.  If the zeolite is required as the pellets for moving bed absorption operation, the moist zeolite initial crystals may be mixed with sodium silicate and a small amount of water into a uniform paste which is extruded, dried and calcined; the pellets so formed may be treated with a calcium salt solution.  Specifications 548,905, 574,911 and 598,238 are referred to.

Title: Improvements in or relating to Methods and Apparatus for Controlling Elevation of Graders and Terrain Leveling Equipment
IPC: E02F3/85
Filed: 1967-03-15
Abstract: 1,181,838. Automatic position control. PROCESS EQUIPMENT CO. OF TIPP CITY. March 15, 1967 [March 17, 1966; April 6, 1966], No.12109/67. Heading G3R. The vertical position of a tool carried by a vehicle is maintained constant, relative to a laser beam swept about the vehicle at a selected height, by automatically controlling the vertical position of the tool in dependence on the output of a laser beam detector which moves vertically in synchronism with the tool. In Fig.1, a steerable motor-driven earth levelling vehicle C has a blade C7 which is carried by a circular subframe C8 supported by adjustable arms C11 and has conventional manual hydraulic controls C6 for blade height, pitch, tilt and horizontal angular position. To detect changes in the vertical position of one end of blade C7, a mast 10 pivoted at an appropriate point 11 on frame C8 carries at its upper end three photo-cell-filter combinations 23f so that when a narrow laser beam, which is swept at a fixed height over the working area, strikes only the centre photo-cell, the blade is in its desired vertical position and this is indicated by a lamp L in the vehicle cab. If, however, the height of the blade rises or falls as the vehicle moves over uneven ground, one of the two other photo-cells is illuminated to cause solenoid operation of a valve (not shown) controlling the appropriate adjustable hydraulic link 50 so that the blade is restored to the desired position. The desired position is selected by manual or tape-controlled operation of a hand wheel 20b adjusting the length of mast 10 through rack gearing 16. A further hand wheel 22b permits rotation of the mast so that the photo-cells may be pointed away from the direction of the laser source during initial setting. A damped pendulum within a container 15 attached to mast 10 maintains the latter vertical by automatic hydraulic control of jacks 13a, 13b which adjust the attitude of mast 10 about pivot 11 in two mutually perpendicular planes. When the hydraulic supply is not available, pendulum 15 is automatically locked to prevent the mast from falling.

Abstract: 568,382. Regulating combustionproduct plant. PESCARA, R. P. Sept. 3, 1942, No. 12483. Convention date, Sept. 3, 1941. [Classes 7 (i) and 7 (vi)] In a free.piston compressor or gas generator in which the pistons 2 are returned by the pressure of gas in one or more cushioning spaces A, this pressure is automatically varied by a source of gas under pressure adapted to respond to variation of at least one operating characteristic of the machine and also to variation in the cushioning pressure for a given position of the pistons and to variation in the length of piston stroke. As shown, the gas generator comprises opposed power pistons 2 integral with pistons 5 in cushioning cylinders 6, one face of each piston 5 compressing air into a receiver 9 communicating with seavenging-air ports 12<1> and 12<2> in the power cylinder 1. A pipe 14 connects the cushioning spaces A and the pressure, in the cushioning spaces is controlled by a slide valve 10 having check valves 15 adapted to admit air to or from the receiver 9 when a port 12<1> or 12<2> in the slide valve registers with a port 13 leading to the pipe 14. The slide valve 10 is actuated from a piston 23 in a cylinder 20 communicating through a restricted port 21 with one of the cushioning spaces A, so that the pressure in the cylinder 20 is substantially equal to the mean pressure in the cushioning space ; this mean pressure depends upon the pressure in the cushioning space for a given position,of the pistons, and also upon the length of the piston stroke. The piston 23 is engaged by a spring 24 and is connected to a bell-crank 26 having a roller 29 acting through an abutment 25 and spring 19 on a piston 17 connected to the piston valve 10. The underside of the piston 17 is connected through a pipe 18 to the receiver 9. A slidable abutment 30 engaged by the roller 29 in the upper part of its path is connected to piston 31 in a cylinder 34 connected by the pipes 33, 18 to the reservoir 9. When the apparatus is used on aircraft, a barometric capsule 35 may be arranged to rock a lever 36 connected to the pivot 27 of the bell-crank 26. The pressure in the cylinder 20 may be modified by providing a check valve 39 opening towards the cushioning space A. An adjustable needle valve 22 controls the restricted port 21. In a modification, the valve 22 is connected by a lever to a piston actuated by the pressure in the receiver 9, and the chamber 20 is connected directly to the cylinder in which works the piston 17 actuating the slide valve 10. Specification 556,454 is referred to.
