Title: Method for preparing highly siliceous zeolite-type materials and materials resulting therefrom
IPC: B01J29/08
Filed: 1964-02-27
Abstract: The Si: Al ratio in the crystal lattice of a crystalline zeolitic aluminosilicate is increased by exposing the aluminosilicate, whilst at least partially in the hydrogen form, to hydrolysis to such an extent that at least 50% of the crystallinity is retained.  The aluminosilicate is treated with a complexing agent which forms a co-ordination complex with the aluminium displaced from the crystal lattice and at least a part of the co-ordination complex is separated from the aluminosilicate.  The complexing agent may be a chelating agent which will form a stable chelate with aluminium; the chelate may be soluble in the reaction medium whilst the alumino silicate is insoluble both before and after chelation.  The chelating agent, e.g. di-(tetraethylammonium dihydrogen ethylenediamine tetra-acetic acid, may also serve to convert the aluminosilicate, at least partially, to its hydrogen form prior to the hydrolysis step.  Synthetic zeolites X, B, D, L, Q, R, S, T, Y, Z, ZK-4 and ZK-5 are referred to in the description as well as natural minerals, e.g. fanjasite. As an alternative, an anion exchange resin may be used as the complexing agent when separation may take place by particle size classification. The initial Si: Al ratio may be between 2: 1 and 6: 1 and that of the product may be as high as 50: 1.  The X-ray diffraction pattern of the zeolite may be substantially unchanged after removal of aluminium which leaves a crystal lattice structure which appears to contain Si atoms which are not actually present.  44 examples are quoted in which ethylene diamine tetra-acetic acid and a number of its derivatives are used with the zeolites referred to above.  In one example a styrene/divinylbenzene anion exchange resin is used on a calcium form of synthetic fanjasite.  The aluminium chelate of resin formed is separated from the aluminium deficient fanjasite by sieving.ALSO:Crystalline zeolitic aluminosilicates in which the Si:Al ratio has been increased are used as catalysts for transforming organic compounds which are catalytically convertible in the presence of acidic catalyst sites.  The Si:Al ratio is reduced by exposing the aluminosilicate, whilst at least partially in the hydrogen form, to hydrolysis to such an extent that at least 50% of the crystallinity is retained.  The aluminosilicate is then treated with a complexing agent e.g. ethylene diamino tetracetic acid which forms a co-ordination complex with the aluminium displaced from the lattice and at least a part of the co-ordination complex is separated from the aluminosilicate.  Other complexing agents mentioned are NaF, NH4F and and eithic acid.

Title: Improvements in Pulse Radar
Inventor: EVANS NOROL THEODORE
IPC: G01S13/72
Filed: 1968-02-20
Abstract: 1,167,671. Pulse radar. HUGHES AIRCRAFT CO. 20 Feb., 1968, No. 8283/68. Heading H4D. In a pulse radar with range sweeps effected sequentially in elevation at each azimuth position, the video returns for each range interval in each range sweep are amplitudequantized and the quantized signals are correlated over several elevations to provide a target detection signal. In the embodiment the video amplitude quantization covers eight steps which are three-bit coded and "hits are enumerated as e.g. 7-hit and the acceptable hit patterns are as shown in Fig. 3 where each three-by-three matrix (" window ") represents adjacent azimuth (columns) and elevation (rows) positions for a particular range interval (see also Fig. 2), a moving window technique is incorporated. Detailed embodiment. Figs. 2, 4.-In the embodiment there are ten range sweeps sequentially in elevation and each range sweep has 400 range intervals. A memory 25, Fig. 4, has a capacity of 4000 words each of eighteen bits and the capacity of a memory 30 is 400 words of six bits (one word for each of the 400 range intervals of a range sweep); for each of the 4000 range intervals in each azimuth position memory 25 contains the three-bit codes corresponding to same range interval in six of the nine positions of the three-by-three matrix. Memories 25, 30 are addressed utilizing counters 34, 35, as shown. When the coded signal for range " bin " C1, Fig. 2 (selected range interval R x ) of azimuth Z 1  and elevation E c  is supplied to register 32, memory 25 supplies for temporary storage to read register 25a three-bit the codes representing the video in related range bins in previous azimuths Z 2 , Z 3  at elevations E c , E B  and E A . Memory 30 simultaneously transfers the three-bit codes representing the video in range bins at B1 and A1 to register 30a. Thus the three-bit codes for all positions of the three-by-three matrix ("window ") 20 are available simultaneously and at the same time as the arrival of the three-bit code at position Cl. A detector 50 determines whether any of the acceptable hit patterns is present in the matrix for each range bin and comprises gating combinations, Figs. 5, 6, 7 (none shown).

Title: Improved means for use in the rotary drilling of bore holes
IPC: E21B19/08
Filed: 1936-03-19
Abstract: 473,835. Borehole apparatus. ROGERS, L. W. March 19, 1936, No. 8293. [Class 85] [Also in Group XXIV] In drilling boreholes, the rotary movement is applied to the tool through a hydraulic coupling of the kinetic type which limits the torque transmitted, and the rate at which the tool is lowered into the formation is controlled in dependence on the relative speed of the impeller and runner of the hydraulic coupling, which varies as the torque transmitted. In Fig. 1, a shaft 10, driven by chain 12, is adapted to drive the drum 26, provided with brakes 28 and supporting the drill through cable 35, at any of four speeds through chains 18, 19, 29, 30, and clutches 16, 17, 33, 34. The shaft 10 also, through clutch 54, chain 48 and shaft 45, drives the impeller 43 of a hydraulic coupling 40, the runner 42 of which drives the drill through chain 52 and rotary table 36, and is fixed to a sleeve 44. Shaft 45 and sleeve 44 carry sun gears 60, 61, meshing with planet gears 63, 64, carried by a cage 62, this gearing being such that speed of rotation of the cage 62 is reduced as slip in the coupling 40 increases. Cage 62, through friction ratchet 72 and gearing 69, 70, drives a cam 67 which acts through a spring-pressed follower 86, arm 85a, friction ratchet, gears 80, 79, irreversible worm gearing 77, 74, and clutch 75 to drive drum 26 to lower the drill. The stroke of the arm 85a is varied by adjusting a stop 92 ; alternatively the cam 67 is replaced by a series of cams of varying lift fixed together and slidable axially. In Fig. 5, the input and output shafts 45a, 50a of the coupling 40 are connected as by belts 102, 103, one of which is crossed, to the sun wheels 100, 101, of a differential gear, the planet cage 104 of which is connected through bevel gears 106, 107, to a shaft 108 carrying a governor 112 connected to a stepped cone 111. A crank 117, driven by an auxiliary motor or through bevel gearing from the belt 102, oscillates an arm 114 carrying a pawl 115 to drive the drum 26 through ratchet wheel 113 and worm gearing 74. As slip increases in the coupling 40, the governor 112 moves the cone 111 which acts through a spring-pulled lever 124 to move a sector 121 with a bevelled corner 122 adapted to cooperate with a projection 123 on the pawl 115 to reduce the effective stroke of the pawl. The governor shaft may also drive a speed indicator 136, Fig. 6, through a centrifugal clutch including pivoted arcuate masses 131 urged by springs against a driven member 134 until the speed becomes excessive. The worm gearing 77, 74, may be replaced by a spur gear train with a brake to prevent the feed being effected except through the ratchet mechanism. Specifications 447,281 and 447,282, [both in Group XXIX], are referred to.

Abstract: 789,733. Turbine and compressor casings. ROLLS-ROYCE, Ltd. Feb. 11, 1955 [March 22, 1954], No. 8379/54. Addition to 695,724. Classes 110 (1) and 110 (3). A structural element for use in an axial-flow compressor or turbine comprises a plurality of blades 11 for a blade row of the machine and a shroud structure for an end of the blades. The shroud structure comprises a first annular or part-annular sheet-metal skin 12 which affords a part of the wall of the working fluid passage of the machine, and a second ridged annular or part-annular sheet-metal skin 13 which is spaced from the first skin at the location of the blade row. The ridged skin is in contact with and is secured to the first skin between adjacent blade rows, the first skin being formed with slots 15 and the second skin 13 being provided with pairs of slots 16, the slots of each pair being radially-aligned with the ends of a corresponding slot 15 in the first skin. Each blade is mounted in the shroud structure by having an end extending through a slot in the first skin and by having portions extending through the two slots in the second skin and being secured thereto. In Fig. 1 the second skin is comprised of a number of sheet-metal rings 13, the flanges 13a of which are welded to the external surface of the shell 12. The angle-section part 14 of each ring is formed with pairs of slots 16 which are radially in line with the ends of slots 15 formed in the inner skin 12. The root end 11a of a blade projects through the slots 15, 16 and is secured, for example, by brazing 17, or by means of lugs 18 at the end of the blade root which are bent after assembly to engage the outer surface of the ridged skin. The rings 13 are provided with flanges 20 and these are secured to an outer casing 21. In the compressor casing shown in Fig. 5 the two sections 25, 26 are connected together by means of a ring 30 and bolts, the ring carrying a row of stator blades 31 which may support at their inner ends a bearing of the compressor rotor. The outer casing 21 is omitted in this construction. In Fig. 4 the root end of the blade is square and the ends of the two slots 16 in the ring 13 are at right angles to each other so that the blade root fits snugly in the slots, being secured by brazing 17. The ends of the blades in Fig. 1 are cut off parallel to the angled sides of the rings 13. In a further construction the blade roots are enlarged to a greater aerofoil section than the vane portions. The ridged skin may have ridges of curved cross-section.
