Title: Improvements in or relating to gas analysing apparatus
IPC: G01N7/04
Filed: 1920-01-28
Abstract: 138,355. Svenska Aktiebolaget Mono. Jan. 29, 1919, [Convention date]. Gas analysis.-In order that one apparatus may be used for conducting successive analyses of samples from different sources, a number of primary gasmeasuring vessels are provided and the connexions are arranged so that at any time the gas from only one of these vessels passes through the remaining members of the apparatus, common to all the vessels. The apparatus shown in Fig. 1, which is actuated in the manner described in Specification 16561/08, has two primary measuring-vessels A, B, connected through liquid seals to a common absorber D, the surplus gas from which passes to a recording-bell E. The outlets from each measuring bell are also provided with branches e, f dipping into receptacles g, h partly filled with liquid and interconnected as by a cord passing over a pulley i, so that by turning the latter to and fro the ends of the branches may be alternately sealed, the gas from the vessel corresponding to the sealed branch being then caused to pass through the absorber, while gas from the other vessel escapes to the atmosphere. Alternatively, the ends of the pipes g, h may be connected to the ends of an oscillating tube k, Fig. 2, partly filled with mercury and provided with an outlet l at the centre, or the vessels g, h may be attached to the arms of a balance m, Fig. 3. The movement of the vessels is effected by the fluctuations of pressure in the actuating-pump C; thus a connexion p, Fig. 4, from the pump leads to a cylinder 6 causing a rise and fall of a piston 3, and this movement serves to rock the wheel i intermediately by the aid of an oscillating duplex pawl 1 and pins 4, 5 engaged alternately on succeeding descents of the piston.

Title: Improvements in or relating to the production of activated alumina
IPC: C07C209/18
Filed: 1958-01-28
Abstract: Activated alumina is prepared from aluminium hydroxide produced by Bayer's process by heating to a temperature of at least 400 DEG C., preferably in the range 400 DEG -600 DEG C., neutralizing with an acid solution in a quantity at least sufficient to convert the sodium compounds contained in the aluminium hydroxide into a salt or salts, and reactivating by heating the material at a temperature within the range of from 400 DEG C. to 600 DEG C.  The acid solution may be a dilute or concentrated solution of an acid or of an acid salt, e.g. of hydrochloric acid, aluminium nitrate, or ammonium chloride, and may be used at a temperature of not more than 100 DEG C.  In an example, a table is given showing the activity of five different samples of catalyst in the dehydration of ethyl alcohol to ethylene. Samples 1 to 3 are prepared from aluminium hydroxide obtained by Bayer's process and activated by heating to 400 DEG C. for four hours in a current of air.  Sample 1 is used without further treatment, sample 2 after washing with hydrochloric acid solution, stirring while the temperature is brought to 100 DEG C., drying, and reactivating at 500 DEG C., and sample 3 after treatment in aluminium nitrate solution, agitating, removing excess water, drying, and reactivating at 500 DEG C. (bringing the pH of the product in suspension from 10 to about 4,5).  Sample 4 is obtained by reacting aluminium nitrate solution and ammonia, thoroughly washing, drying, and activating at 500 DEG C.  Sample 5 is a commercial dehydration catalyst.  Organic compounds deposited on the surface during use may be eliminated by periodic treatments with a current of air at 350 DEG -400 DEG C. Acetonitrile may be prepared by passing a mixture of equimolar parts of acetic acid vapour and ammonia, at a flow rate of 20 moles of the mixture per litre of catalyst per hour, over the catalyst heated to 380 DEG C.  Methylamines may be formed from methanol and ammonia, and dimethylaniline from aniline and dimethyl ether or methanol.

Title: Improvements in or relating to radio navigational aid systems
IPC: G01S1/50
Filed: 1947-02-06
Abstract: 644,367. Radio navigation. PHILIPS LAMPS, Ltd. Feb. 6, 1947, No. 3643. Convention date, Feb. 5, 1944. Addition to 642,094. [Class 40 (vii)] Relates to omni-directional phase beacon systems as described in the parent Specification for enabling a mobile receiver to determine its bearing relative to the beacon in which the beacon radiates two fields on a common carrier amplitude modulated respectively with harmonically-related frequencies w and nw so that the modulation phase of the two fields at a distant point is directly proportional to the bearing # of that point and means being provided at the receiver for comparing the phases of the demodulated signals to obtain a quantity which is indicative of the bearing # and which is a function of (n1)#. The accuracy of such a system is increased by making n large, e.g. n=8, but this results in (n1) ambiguities in the 360 degree range of bearings and according to the present invention the ambiguities are resolved by radiating a third field having a modulation which is either proportional to the bearing or independent of bearing ; in the former case the modulation frequency may be ¢w, 2w, ¢nw or 2nw and in the latter case the modulation frequency may be w/m or nw/m where m is an integer differing from n and in either case at the receiver the modulation of the third field is compared in phase with that of the first or second fields to give an unambiguous but less accurate indication of the bearing #. In one embodiment of the parent Specification two cardioid directive patterns of the same carrier frequency are rotated in the same direction at angular speeds of wand nw and in one embodiment of the present invention, Fig. 1 (not shown), a further cardioid of the same carrier frequency is rotated in the same direction at a speed of 2w. At the receiver the signals obtained on demodulation having respective frequencies w, nw and 2w are separated by filters 25, 26, 27 and the 2w and nw signals are applied respectively to phasemeters 30 and 29 together with further signals of the same frequencies obtained by frequency multiplying the w signal at 31 and 28 by 2 and n respectively so that the meter 29 gives an accurate but ambiguous indication of # as in the parent Specification and meter 30 give a less accurate but unambiguous indication of #; if required a single phasemeter may be alternately connected to the two pairs of outputs from 26, 28 and 27, 31. Alternatively the phase difference may be measured by a cathode-ray tube as in the parent Specification. When the modulation phase of the third field is independent of bearing, the angle # may be determined unambiguously as in Specification 642,182. Specification 642,183 also is referred to.

Filed: 1974-04-01
Abstract: 1468185 Fluid-pressure control circuits AUSTRALIAN IRON & STEEL Pty Ltd  1 April 1974 [12 April 1973] 3630/76 Divided out of 1468184 Heading F1P [Also in Division F2]  In the circuit shown in Fig. 1, a motor 9, which drives a rock-drill, is fed through a valve 6, a line 18 and a line 12 in a flow-divider 5 whilst a drillfeed motor 10 is driven through a valve 8 and a line 13. An adjustable orifice 22 determines the flow in the line 13. This orifice is in a valve 17, Fig. 2, and is normally held at a maximum by a spring 23. When the drill, driven by the motor 9, encounters hard rock, the pressure in line 18 rises. The rise is fed via line 19 to a piston 20 of the valve 17 and acts to progressively close the orifice 22 thus decreasing the rate at which the drill is fed into the rock. An anti-stall valve 24, Figs. 1, 4 has an orifice needle 33 which is lifted from its seat to return fluid to the reservoir if the pressure in a passage 36 rises above a pre-set limit due to the drill engaging hard rock. A screw 35 provides the pre-set load on a spring 30A. Valves 6, 7, 8 are held in position by detent devices and valve 8 is automatically returned to its retract position when the drill feed reaches the end of its travel thereby causing a rise in pressure in the feed line 13A. When the drill feed is fully retracted an overload valve 39 opens. Safety relief valves 40, 41 are provided in case the feed-rate is not reduced. A ram 11 locks the drill pillar between roof and floor in a mine. Fig. 3 shows the spool valve 8 with the detent device 37 and relief valve 39. A member 61 is forced against a seat 62 by a spring 63, the pressure of which is adjusted by a screw 64. When the motor 10 has reached the end of its travel, pressure rise through a bleed 78 lifts member 61 off its seat so that spring 52 can move the spool 45 to the null position. Relief valve 39 is a poppet valve. The anti-stall valve is also incorporated. A pressure rise in inlet 99, due to the drill approaching stall conditions, acts on piston 93 to open valvemember 94 against a spring 97. Screw 101 adjusts the latter.
