Title: Method and apparatus for the dispersal of fog
IPC: A01G13/06
Filed: 1959-06-30
Abstract: 868,342. Dispersing fog. SOC. BERTIN & CIE. June 30, 1959 [July 1, 1958], No. 22467'/59. Class 6(2). [Also in Group XXVI] A method of dispersing fog consists of directing into the affected zone the jet emerging from a jet engine, thereby initiating the formation of convection currents in the fog, and assisting the evaporation of the moisture droplets comprising the fog. In order to clear fog from an aircraft runway, batteries of jet engines 1, 2 are arranged on each side of the runway 3 in such a manner that the two sets of jets collide at the centre of the runway and deflect each other upwards, thereby initiating convection currents. The jet engines may be pivotally mounted on the ground, or may be provided with adjustable nozzles so that the directions of the jets may be varied in accordance with the wind direction. Further, the speeds of ejection of the jets of the two sets of engines may be adjustable independently of each other by providing valves 21 and 22 in the fuel feed pipes 23 and 24 of the two batteries 1 and 2. The arrangement may be modified by burying the jet engines and providing them with nozzles at ground level. The method according to the invention may be rendered operative at sea by mounting a jet engine on a ship. Specification 850,404 is referred to.
Patent GB-406016-A (GB)
Title: Improvements in or relating to the manufacture of artificial filaments, films and the like
IPC: D01F2/28
Filed: 1932-08-11
Abstract: Artificial filaments, threads, ribbons, foils, or films of organic derivatives of cellulose are subjected during or after their formation to the action of a medium containing in a non-solvent diluent a liquid organic solvent for the cellulose derivative in high concentration and in low concentration a dissolved solid substance which has at least some solvent or swelling action on the cellulose derivative, and simultaneously or subsequently the materials are subjected to a stretching operation.  The medium referred to may be the coagulating liquid employed in the production of the materials by a wet spinning process.  The solid solvent or swelling agent may be urea, thiourea, guanidine, or an alkyl or aryl derivative thereof, or it may be an inorganic salt such as zinc chloride or potassium thiocyanate.  The liquid organic solvent may be of low, medium, or high boiling point.  The non-solvent diluent may be water, ethyl alcohol or other mono- or polyhydric alcohol, or a coal-tar or petroleum hydrocarbon, or a chlorinated compound sych as carbon tetrachloride.  Stretching may take place in stages and the materials may be treated with softening liquid prior to or during each stage. Filaments may be stretched while in warp formation, or in hanks, or while travelling from bobbin to bobbin, or continuously with their production by dry or wet spinning processes.  The process may be carried out at room or higher temperature.  Filaments and threads of cellulose esters may be subjected to shrinking or saponifying treatment continuously with the softening and stretching operation. The stretching tension may be applied continuously or intermittently and differentially strained yarns may be obtained.  The softening liquid may be completely or partially removed from the materials by washing prior to drying and solvents, swelling agents, or salts may be present in the washing liquid in order to avoid delustring.  The washing step may be omitted in order that the solid substance may be left in the materials after the liquid solvent has evaporated. In an example, cellulose acetate solution is extruded into an aqueous solution containing 5 per cent potassium thiocyanate and 45 per cent diacetone alcohol.  The filaments are stretched, washed, dried, twisted, and wound.  In other examples the coagulating bath or subsequent treatment bath contains about 3 per cent urea and a high concentration of ethyl lactate or dioxane.  Specifications 177,868, 179,234, 277,089, 323,790, 336,217, [all in Class 2 (ii)], 340,324, 340,436, 340,437, 370,430, 371,461, 371,910, 375,423, 375,424, 378,858, 380,819, 389,823, 392,185, 400,589, 400,597, 400,938, 400,946, 401,679, 402,106, 402,141, 403,106, 405,619, and 405,676 are referred to. The Provisional Specification describes also processes in which instead of using a coagulating bath containing a liquid solvent and a dissolved solid solvent or swelling agent, one or both of these substances is contained in the spinning solution or in a subsequent treatment bath.

Abstract: 950,726. Mechanical switches, without quickaction. BURGOT AUTOMATIC ALARMS Ltd. Sept. 30, 1960 [July 1, 1959], No. 22560/59. Heading H2B. [Also in Division H4] In an impulse transmitter for transmitting a complete multidigit number at a single sitting operation, a series of discs, freely rotatable about a common axis, each disc having on one side a gapped printed circuit and on the other side a wiper which is electrically connected to the printed circuit and which wipes the conductors of the next disc, are successively driven by the engagement of abutments on each disc, the relative arcuate spacing of the abutments determining the number of impulses sent by each disc. The insulating discs 5 (Fig 1) are mounted on a shaft 1 which is geared to a motor 3 and are separated axially by spacing members 6. The first disc (from the gearing) is rigidly attached to the shaft while the first four discs have continuous rings of copper 8 on one face and wipers 11 connected to the other face. The next seven discs have a gapped track 10 (Fig. 3) on one face and a continuous track 9, to which is attached a wiper 11 (Fig. 4), on the other face. Studs 13 on each disc serve to transmit the drive from one disc to the next after the requisite number of impulses have been sent, the studs being attached to the discs during manufacture. Line wires are connected to the frame 2 of the instrument and to a wiper 12 which wipes the last disc. When the first disc rotates, its stud 13 eventually strikes the stud 13 on the second disc and so causes the latter to rotate, the process being repeated for all the discs. Springs 14 engage detents 15 in the periphery of each disc to hold them in the wipes the gapped track 10 on the fifth disc and so causes impulses to be sent to line until the respective studs 13 engage and so prevent further relative movement between the discs. Similarly, impulse trains are sent for each of the following discs until they are engaged by the preceding one, until finally movement of the last disc off-normal causes all the discs to be home position. The continuous rings on the first four discs allow exchange equipment to be seized before the number is " dialled." When the fourth disc is caused to rotate its wiper 11 homed. Each disc may have more than one printed circuit track and more than one wiper associated with it.
