Title: Improvements relating to fire-fighting apparatus for delivering foam or water
Inventor: NEUHAUS HANS WERNER SAMUEL
IPC: A62C5/00
Filed: 1958-11-13
Abstract: 931,351. Fire-extinguishing. PYRENE CO. Ltd. Nov. 13, 1959 [Nov. 13, 1958; April 8, 1959], Nos. 36564/58 and 11879/59. Class 47. [Also in Group XXVIII] Apparatus for directing mechanical foam or water on to a fire has a tubular jet-forming member mounted to turn in a casing forming part of the delivery line so that, in one position, the tube is aligned with the water stream wherein air is entrained in the jet or jets, while in a second position, the tube is transverse to the stream which then flows round it, means being provided to prevent air from being entrained. The jet-forming tube 9 is mounted between diametrically-opposite openings 11, 12 in a hollow sphere 10 rotatably mounted, under the control of an hydraulic ram, in a tubular casing 2 connected to the water-supply and to the delivery nozzle. Another pair 13, 14 of diametrically-opposite openings, at right angles to the openings 11, 12, is formed in the sphere which is guided in its rotation by members projecting from the casing and engaging annular grooves in the sphere in planes at right angles to the axis of rotation. When foam is to be delivered, the sphere is rotated so that the water passes through the tube 9 and draws in a supply of foam-stabilizer through an opening 32 while air is drawn in through an opening 25; when water only is to be delivered, the sphere is turned so that the water flows through the apertures 13, 14 and no suction occurs to draw in the foam-stabilizer, the air supply opening being closed as described in Specification 931,353. Specifications 602,654, 842,461 and 931,352 also are referred to.
Patent GB-366076-A (GB)
Abstract: 366,076. Anti-aircraft gun sights. OFFICINE LOMBARDE APPARECCHI DI PRECISIONE, 0. L. A. P. SOC. ANON., 2, Viale Lombardia, Milan, Italy. Julv 29, 1930, No. 22757. Convention date, July 29, 1929. [Class 92 (ii).] The gun data for firing at moving aerial targets to correct for variations in the height of the target during inclined flight are obtained by determining from the movements of telescopes which continuously follow the target in elevation and azimuth (1) the angle po which the plane of flight OPoPs, Fig. 1, passing through the observation point 0 and the present and future target positions P‹, Ps, makes with the vertical plane of sight OPoPo<SP>1>, and (2) the lead angle #gamma in the plane of flight. The data thus determined are then conveyed to optical means for setting up the angle of elevation #s and the angle of training ## for aiming the gun. Fig. 2 shows the telescopes 1, 2 for following the target in training and elevation, the components of motion being conveyed to a right-angled triangle mechanism the hypotenuse h of which gives the angular velocity #gamma in the plane of flight and the inclination P‹ of the plane of flight. Fig. 3 shows means for plotting a curve for the reciprocal_of wy on a moving band 41 the inclination of the tangent to the curve giving the angle gamma<o>, Fig. 1. The Specification also describes with reference to Fig. 4 (not shewn) an apparatus which reproduces the right-angled triangle PoQR, Fig. 1, the sides of which represent the components of target speed dx/dt and xo#gamma along and at right-angles respectively to the line of sight OPv. The target speed v and the rate of change of range dx/dt are thus determined when gammao is known. The apparatus shown in Fig. 5 reproduces the triangle OWPo, Fig. 1, on the upper disc 103 and the triangle OWP, on the lower disc 123. The differences between the distances WPo=vto and WPs=vts are by means of a differential gear 117 and division apparatus 118 converted into ts - to which is collated with the time of flight. This is obtained from a camoid 133 and conveyed by a shaft 131 to a differential gear 138 the planetary pinions of which operate a switch 139 to control a motor 140 for setting the pin 113 to a position corresponding to P,. The apparatus also gives continuously the difference gammas-gammao which is the lead #gamma in the plane of flight. Fig. 9 shows how a mark 143 is moved in. an arcuate guide in accordance with #gamma the guide being set at the angle po. The mark is then viewed by adjusting the prism M of an optical apparatus by turning handles 163, 167 the movements of which give the angles of elevation and training for the gun.

Title: Improvements in the purification of acetylene
IPC: C07C7/177
Filed: 1930-12-09
Abstract: Crude acetylene derived from thermal treatments of gases comprising hydrocarbons, which contains as impurities highly unsaturated hydrocarbons such as allylene, diacetylene and allene, is purified by polymerizing the unsaturated hydrocarbons by bringing the crude acetylene into contact with sulphuric acid, phosphoric acids, acid salts of these acids, anhydrous metal halides having an acid reaction in aqueous solution, such as aluminium chloride, ferric chloride, stannous chloride, or zinc chloride, or mixtures of these substances. In a modification of the process there are employed as polymerizing agents materials having a large superficial area, such as active carbon, silica gel, kieselguhr, or bleaching earths, or finely divided oxides of metals of groups 2 to 7 of the periodic system which are not reducible to the metal with hydrogen at temperatures below 600 DEG  C., such as the oxides of manganese, chromium, uranium, molybdenum, tungsten, titanium, thorium, tin, cerium, aluminium, or calcium, or mixtures of these substances, the purification being carried out at 200-300 DEG  C.  The working conditions, particularly the temperature, depend on the activity of the polymerizing agent and on the acetylene content of the gas.  If required, diluents such as hydrogen or nitrogen may be added, and the purification may be carried out at atmospheric, reduced or increased pressure.  The polymerizing agents may be precipitated on or dispersed in carriers such as pumice stone or burnt fireclay.  In examples: (1) a gas containing acetylene, hydrogen, methane, and nitrogen, obtained by the treatment of natural gas in an electric arc, is passed at 15 DEG  C. through a trickle tower in which it comes into contact with 95 per cent sulphuric acid; (2) a gas containing acetylene, hydrogen, methane, and nitrogen, obtained by the treatment of methane in the electric arc, is led over silica gel at 250 DEG  C.; (3) a similar gas is washed with a solvent such as cyclohexanone under pressure and the pressure fractionally released giving a gas containing 80 per cent of acetylene, which is led over active carbon at 275 DEG  C.; (4) a gas containing acetylene, methane and nitrogen, obtained by the treatment of natural gas in an electric arc, is passed over natural granular pyrolusite or over pyrolusite deposited on pumice stone at 270-280 DEG  C.  Specification 340,787 is referred to.

Abstract: 1500344 Quadraphonic systems EMI Ltd 21 Sept 1976 [12 Sept 1975] 37541/75 Heading H4R At least four input signals are processed for recording or transmission by forming a corresponding number of composite signals, one of which is the sum of the signals while the remaining signals are forms of difference signals, two of the difference signals are quadrature modulated on a suppressed carrier wave, a third difference signal is modulated on a pilot signal, which is a phase reference for the suppressed carrier, and the modulated signals are combined with the sum signal to produce a combination signal. As described the four quadraphonically related signals LF, RF, LB, RB, are matrixed to produce a sum signal S 1 =LF+RF+LB+RB, a left/right difference signal D 1 =(LF+LB)-(RF+RB), a front back difference signal D 2  = (LF + RF) - (LB + RB), and a diagonal difference signal D 3  = (LF + RB) - (RF + LB). The sum signal forms a base band signal S 1 , the difference signals D 1  and D 2  are modulated in quadrature on a suppressed 38 kHz carrier, and the difference signal D 3  is modulated on a 19 kHz pilot to a depth of 70%, the signal D 3  being frequency limited so that its side-bands do not overlap the sum signal band. On reproduction the pilot tone is recovered, for demodulation of the 38 kHz signal, using a phase locked loop which is heavily "slugged" so as not to respond to the amplitude modulation. The resulting combination signal can modulate a carrier for transmission or it can be recorded on a disc.
