Title: Improvements in or relating to a solution and process for imparting fire resistance to cellulosic materials
IPC: D06M11/71
Filed: 1952-10-20
Abstract: 731,176. Fireproofing cellulosic materials. TITAN CO., Inc. Oct. 20, 1952 [Oct. 30, 1951; Nov. 27, 1951], No. 26285/52. Class 140. Fibrous cellulosic material is impregnated with an aqueous solution of tetravalent titanium chloride containing a phosphate dissolved therein, partially dried to form a transparent gel on the material, treated with an alkaline neutralizing agent, washed and dried. The phosphate is not necessarily water-soluble but must be soluble in the solution of titanium chloride: specified phosphates are the alkali phosphates; magnesium and calcium phosphates. The solution may contain 50 to 150 g./l. of titanium, approximately 1.3 to 2.0 parts by weight of chloride and approximately 0.02 to 0.17 parts by weight of phosphorus for each part of titanium. To improve the fire-resistance and glow-resistance, antimony trichloride in amounts up to 4 parts by weight antimony for each part of titanium may be added. Sodium carbonate and ammonium hydroxide and carbonate are specified neutralizing agents, to which soluble silicates (e.g. sodium, silicate) may be added. Such soluble silicate may be added to the cellulosic material prior to impregnation or after neutralization. Materials which may be fireproofed include cotton, linen, regenerated cellulose, viscose and cellulose acetate, kapok, hemp, wood and wood products such as pressed board, cardboard, batting, paper, wood flour and sawdust. In an example antimony trioxide is added to a solution of hydrochloric and phosphoric acids, and titanium tetrachloride added with agitation and cooling to the slurry so formed. The solution thus obtained is diluted to a titanium content of 60 g./l. and used to impregnate cotton cloth. The cloth is partially dried by exposure to the atmosphere to gelatinize the treating agent and then treated in sodium carbonate solution containing sodium silicate, washed and dried. Specification 698,742 is referred to.

Patent GB-1091019-A (GB)
Title: Spark ignition systems for internal combustion engines
IPC: F02P3/05
Filed: 1966-06-15
Abstract: 1,091,019. Ignition systems. FORD MOTOR CO. Ltd. June 15, 1966 [June 25, 1965 (2)], No. 26662/66. Heading F1B. Energy is supplied from a source of electrical energy to a storage device 11 during part of an ignition cycle and thus energy is then fed through the secondary winding 12 of an ignition coil to a spark plug 17. The time that the energy is supplied to the storage device is controlled by the voltage of the source. The storage device may be the primary winding of the ignition coil. As shown when the contact breaker points 58 open the bias on the saturable switching core is removed and the flux level falls. This induces a negative potential in the feedback winding which turns the transistor 36 on to establish a current in the primary winding 11 and the winding 33. A negative potential appears at the dot marked terminal of feedback winding 75 thereby turning the transistor fully on by virtue of the feedback action. Current through the winding 33 provides sufficient magnetizing force on the saturable switching core 51 to drive it into a saturated condition. When the core reaches the saturated state the feedback voltage falls to zero thereby turning off the transistor 36 and stopping current flow in the primary winding 11. This induces an ignition voltage in the secondary winding 12. The core 51 may be a conventional toroidal ferrite core and the cross-bar 91 may be a solid piece of soft iron. The flux produced by the winding 92 flows partly through that part of the core carrrying the winding 52 and partly through the part of the core carrying the winding 33. This flux flows in the inner part of the ring. With a low battery voltage there is only a small current in the winding 92 and thus only a small permanent flux whereas with a high battery voltage there is a corresponding large permanent flux. With low battery voltage and the low current in the winding 33 and the large flux charge to be effected, the flux charge takes a longer time than with a high battery voltage. This in turn produces a longer period during which the transistor is on and during which current flows in the primary winding 11 of the ignition coil 10. Modifications in which the cross-bar 91 of the core are omitted are described. A condenser discharge ignition system is described.

Abstract: 532,982. Elastic fluid turbines. ENGLISH ELECTRIC CO., Ltd., and YATES, H. G. Sept. 28, 1939, No. 26808. [Class 110 (iii)] The admission valve and the pass-through valves of stages beyond bleeder points are opened and closed in correct proportion by a speed-responsive device and are controlled by pressure-responsive devices at the bleeder points so that on a variation of the pressure at any bleeder point the valves in front of the point are moved oppositely to those behind that point. Fig. 2 shows an admission valve 5 and stage or pass-through valves 6, 12. The valves are connected to the corners of triangular levers J, K supported by a lever 4 from a speed-responsive device 2 and constrained by vertical slides 7, 13 of bleeder pressure responsive devices 9, 15. The pivotal connection F between the levers J, K is guided to move in a vertical direction. The device 2 lifts the valves equally and the valves are proportioned to produce the correct flow. An increased pressure at 15 moves the slide 13 to open valve 12 and close equally the valves 5, 6. An increased pressure at 9 moves the slide 7 to close valve 5 and open valves 6, 12 equally.

Filed: 1951-11-16
Abstract: <PICT:0701244/IV (b)/1> The chlorination of methane includes the steps of passing a gaseous stream of methane and chlorine in contact with a fluidized mass of surface - catalyst particles in a reaction zone maintained at a temperature substantially in the range 300-370 DEG C., the molar ratio of methane to chlorine being in the range 1:3-6 to 1:4; removing the reaction products from contact with the particles and separating carbon tetrachlorine and perchlorethylene from the other components of the reaction products.  In the Figure a reactor 2 is provided with conduits 16 and 18 for the introduction of separate streams of reactants which are introduced below the level of the surface-catalyst particles when they are at rest.  The reactor is in fluid connection with exhaust conduit 4 having a thermometer 28 inserted therein.  A conduit 6 leads from the exhaust conduit 4 to condenser 8 which is connected with accumulator 10 having a vent 12 for separating the hydrogen chloride formed during the chlorinolysis reaction.  Conduit 14 conducts the condensed reaction products to means for effecting separation and purification.  Thermometers 24 and 26 are provided for determining the temperature of the fluidized catalyst bed within the reactor.  In carrying out the process of the invention the reactor 2 is filled with a suitable surface-catalyst material, preferably having a particle size in the range 60-100 mesh to approximately one-third the height of the reactor.  The catalyst is heated to within a few degress of the reaction temperature and separate streams of chlorine and methane are introduced through the conduits 16 and 18.  The surface catalyst material used may be for example, carbon, charcoal, synthetic aluminium silicate, synthetic silica-alumina gel, silica gel and Fuller's earth.  In the examples chlorine and methane are passed over fuller's earth at 300 DEG C., 325 DEG C. and 360 DEG C. in the application described to give perchlorethylene and carbon tetrachloride with small amounts of hexachlorbenzene and hexachlorethane.

IPC: F16F9/26
Filed: 1955-09-21
Abstract: 771,299. Hydraulic shock absorbers. GRANET, C., ROLAND, G., and CRAUC, R. Sept. 21, 1955 [Sept. 22, 1954; Aug. 2, 1955], No. 27002/55. Class 108(3). A hydraulic damper comprises a crank 41 rigid with a shaft 42 and engaging with doubleheaded pistons 31, 32, slidable in a cylinder 21 above which is situated a reservoir 24, flow of liquid to which, from working chambers 55, 55<SP>1</SP>, defined by the piston heads 31, 32, and the closed ends 26, 27, of the cylinder, is controlled by non-return valves 48 (one valve only, shown in Fig. 2) having variable spring-loading controlled by a cam 56 rigid with the shaft 42. The arrangement is such that as the crank 41 is displaced from a central position (shown) the spring-loading of the valve 48 is progressivelyincreased. As shown, the cam 56 comprises a pair of diametrically opposed concave recesses 61 (one recess only shown in Fig. 2) formed in a ring 56 secured to a side face of the crank 41. Each valve 48 is slidable in a bore 47 formed in the body of the damper and closed on its outside by a screw-threaded plug 50. The latter is formed with ports 51, 52, which comprise a seating for the valve 48 and connect with a passage 54 leading to the chamber 55. A further passage 62<SP>1</SP> leads from the valve 48 to the reservoir 24. Each piston has a non-return valve 37 permitting flow from the reservoir 24 to the cylinder. The lift of the valve 37 may be limited by a member 64. In a modification, Fig. 1 (not shown), the concave recesses forming the cam portions 61 are replaced by flats. In opreation, as applied to the suspension of a vehicle, the position shown in Fig. 2 corresponds to normal static loading of the vehicle. Under a heavier static loading due to the action of the cam surface 61 on the spring loading of the valve 48, the resistance to deflection of the damper is increased.
