Title: Improvements in or relating to direction finding systems
IPC: G01S1/02
Filed: 1954-05-07
Abstract: 755,886. Radio navigation. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 7, 1954 [May 7, 1953], No. 13449/54. Class 40 (7). In a system for determining the direction of a body M shown in a plan view in Fig. 1 with respect to a fixed point O, a directive transmitter beam located at the point executes a conical scan whilst the transmitter is controlled so as to emit a constant frequency carrier pulse modulated at F1, F2, F3 and F4 as the beam scans in succession each of four zones defined by two planes OP1, OP2 cutting at right angles along the axis of the cone. In a receiver carried by the body the signals D1, D2, D3 and D4 received respectively at each of said frequencies are integrated and then compared to derive the differences D1-D3 and D2-D4. These differences are proportional respectively to the rectangular co-ordinates of the displacement OM of the body from the core axis O in terms of axis OX, OY, bisecting to four zones. Fig. 4 shows one embodiment of the transmitter in which an offset aerial 10 is rotated in the focal plane of a paraboloid 11 under the control of motor 13 and is energized by a transmitter 14 operating at a constant radio frequency. The transmitter is pulse modulated by a modulator 16 under the control of a switching device 17 synchronized with the aerial scan by a drive from motor 13. Switching device 17 comprises a disc 18, Fig. 6, which is rotated between a light source and photo-cell and is formed around its periphery with serrations 25 of constant width but different spacing in the four quadrants whereby the transmitter is modulated with a different frequency in each of the four zones successively scanned by aerial 10. In the receiver, Fig. 7, the four frequencies are separated by filters 43-46 and applied to rectifiers 47-50 which integrate the corresponding signals D1-D4 and apply them to comparison devices 51. and 52. to derive the differences D1-D3 and D2-D4. The input of the receiver is a crystal rectifier 39 which feeds an amplifier 40 provided with an A.V.C. system 12, 41.

Abstract: 1284059 Pipe-line cleaning devices CONCO Inc 6 May 1971 [25 May 1970] 13530/71 Heading F2N A pipe cleaning device is propelled through the pipe by liquid jets discharged through nozzles 64 and includes an hydraulic motor M of a known gerotor type, Fig. 5 (not shown), for driving the cleaning tool, e.g. spiral saw 16. Liquid supplied by a hose 62 to a blind bore 60, supplies both the jet propulsion nozzles 64 and the motor M, the latter through a pipe 74. Liquid exhausted from the motor M is fed through a rotatable elbow, Fig. 4 (not shown), selectively positionable to direct the liquid jet either upstream of the device, for pre-flushing the pipe walls, or downstream of the device. Skids 24, for engaging the pipe walls, are mounted on a split ring 32 clamped to the motor housing. The hose 62 has sufficient tensile strength to pull the device rearwardly through the pipe against the jet propulsion forces to flush deposits loosened during forward travel of the device.

Classes 83 (2), 83 (3) and 83 (4). A spiral cutter blade is made by heating a blank whilst located between a pair of spiralforming dies, and then closing the dies to impart the desired spiral contour to the blank. A cutter blade 18, Fig. 1, for use in cutting tools such as reamers, end mills or shell mills, is made by heating a carbide blank 25, Fig. 5, to a plastic condition between dies 27, 28, and then pressing it to form a cambered blank, Fig. 3 (not shown), heating the cambered blank to a plastic condition between a further set of dies 39, 40, Fig. 7, and then pressing it to form the spiral twist in the blade. The blank 25 is of sintered carbide and is heated in the dies 27, 28 to 2600‹ F. by a high-frequency coil, and in the dies 39, 40 by another high-frequency coil 47. Both sets of dies are made of copper to permit rapid conduction of heat from the blank and hence to reduce the time during which the blank is at a high temperature and subject to oxidation. The pressed blades 18 are located on seats 20 in a cutter body 17 and are brazed thereto.

Title: Demethylation of methylbenzenes
IPC: C07C4/18
Filed: 1947-05-29
Abstract: Methylbenzenes are demethylated by contacting with activated alumina at 800 DEG  F. upwards, preferably 1000-1200 DEG  F., and under a partial pressure of hydrogen of at least 100 p.s.i.g.  Toluene, xylenes, and trimethyl benzenes such as mesitylene are specified feedstocks, also mixtures such as toluene and xylene or fractions containing one or more of the reactants.  In general, the hydrogen partial pressure is 100-3000, preferably above 500 p.s.i. Preferably the molar ratio of hydrogen to methyl benzenes is at least 2 : 1, especially 4 to 10 : 1 or more.  The contact time is correlated with hydrogen partial pressure, temperature, and catalyst activity and is generally below 50 secs.  Space velocities are usually 0.2-5, preferably 0.6-1.0.  Aluminas of high specific surface areas are preferred.  Commercial activated aluminas are generally dried, e.g. at 1050 DEG  F. for 2 1/2 hours, before use.  Aluminium oxide hydrate may be calcined to give a dehydrated oxide substantially in the gamma form. Preferably, alumina is the sole catalyst and is used at 1050-1200 DEG  F.  Hydrogen halide, e.g. 1-6 mol. per cent of the reaction mixture may, however, be present when preferred temperatures are 900-1100 DEG  F.  Comparative figures are given for conversions of toluene, xylenes, and a crude 329-380 DEG  F. fraction using activated alumina catalysts and Cr2O3-Al2O3, SiO2-Al2O3 or silica gel.

Abstract: 1,235,277. Rotor assembly. BOEING CO. 19 March, 1969 [22 March, 1968], No. 14437/69. Heading B7W. A rotor assembly for a vertical lift aircraft comprises a rotatable hub 12, a rotor blade 14 retained on the hub by a universal bearing 17 having a centre about which the blade may rotate to allow blade pitch changes or, pivot to allow lagging and flapping, and a resilient bearing 30 restraining the blade against centrifugal forces but allowing pivotal and rotational movement of the blade about the fixed centre of bearing 17. Bearing 17 comprises a socket 20 rotatably holding a ball 18 in which a shaft 28 integral with blade 14 is slidable; socket 20 is mounted on an extension 22 of hub 12. The resilient bearing 30 has a centre substantially coincident with the centre of ball 18, and is mounted between shaped supports 34 on hub extension 22 and 40 on rotor blade extension 42 ; bearing 30 comprises alternate part spherical plates (36) and elastomer (38), Fig. 3 (not shown), so that the bearing absorbs centrifugal loads but allows rotation and pivoting of blade 14 about the centre of ball 18. In the event of bearing 30 failing, supports 34 and 40 would interlock to prevent blade 14 leaving the hub. Lag-lead motion is damped by a damper 52 connected between a support 22 for an adjacent blade and a universal joint 56 on bearing support 40; motion about pitch and flapping axes is substantially unaffected. A roller 46 on support 40 co-operates with conical stops 48 and 50 on hub 12 to prevent the blade and hub binding at the limits of flapping motion.
