Title: Extraction of refractory metals from their halides
Inventor: HNILICKA MILO PELC
IPC: C22B34/14
Filed: 1961-07-29
Abstract: <PICT:0948659/C3/1> <PICT:0948659/C3/2> Apparatus for the production of refractory metals, particularly zirconium, by the reduction of their halides consists of a furnace in which is situated a substantially horizontal retort, one end of which contains the metallic reducing agent and forms a reduction zone, while the other end contains the solid halide and constitutes a volatilization zone, the two zones being thermally isolated from each other except for a small conduit in the upper part of the retort through which halide vapour passes.  The volatilization zone is equipped with a condenser upon which halide vapour may be caused to condense.  In the apparatus illustrated in Fig. 1, furnace 10 is equipped with independently controllable heating elements 18 and with blowers 19.  Retort 20 is divided by thermal barrier 38 into reduction zone 22 in which is placed container 26 of reducing metal 28, and volatilization zone 24 in which are containers 30 of halide 32.  Halide vapour passes through filters 33, conduit 40 and distributer 42 to the reaction zone.  Condenser 50 is normally exhausted by pump 56, but cold air may be drawn in through valve 57 if necesary to condense halide and moderate the reaction.  The retort is initially exhausted through passage 66 but the reaction is then carried out under a slight positive pressure of argon supplied by pipe 43. Passage 66 leads to manifold 68, one branch of which leads to safety valve 82 ; a second branch leads via valve 83 to exhauster 84, which is also connected to manifold 68 via valve 75 and condenser 74.  72 represents a furnace enclosing the apparatus shown.  Initial exhaustion is carried out with valve 83 open and valve 75 closed, after which valve 83 is closed and argon admitted to the retort.  Should condenser 50 be unable to retard the reaction sufficiently, valve 75 is opened to draw vapour over condenser tubes 74 through which cold air is drawn from valve 78 by pump 76.  Halide condensed on tubes 74 is subsequently revolatalized by closing valve 78 and drawing through hot furnace gases via valve 80. Furnace 72 ensures that halide condenses only on tubes 74.

Abstract: 1,242,000. Non-woven fabric, lap forming apparatus. MONSANTO CO. 11 June, 1968 [16 June, 1967], No. 27774/68. Headings D1N and D1R. Non-woven fabric is made by spinning continuous filaments from a welt containing at least 10% nylon, attenuating the filaments and depositing them on a moving belt as a random web, advancing the web through a chamber filled with an "activating gas" wherein the filaments absorb the gas, removing the gas from the filaments whereby bonding occurs at a majority of crossover points of the filaments. The "activating gas" is one which is a sufficiently strong Lewis Acid to form a complex or intermediate with the -NHCO- linkages in the nylon and is capable of being absorbed and desorbed thereby. The activating gas may a hydrogen chloride, boron trifluoride, sulphur dioxide or sulphur trioxide. Preferably the humidity of the gas is above 25%. The gas can be diluted with air. The gas can be removed from the filaments in an alkaline wash bath (30) or by heating. Prior to contact with the gas the web can be consolidated by spraying a binder solution, e.g. nylon ligaments in formic acid, onto the web. The web can be hot calendered prior to or after contact with the gas. A suction box situated beneath the moving belt may be used to assist collection of the filaments on the belt. Deflector plates (24) mounted adjacent the edges of the belt where the filaments are initially collected, are provided so that the edges of the web formed by a traversing aspirator (14) are straight and of uniform density.

Title: Improvements in and relating to the stabilization of polypropylene glycols
IPC: C08G18/48
Filed: 1960-08-12
Abstract: A process for obtaining stabilized and improved polypropylene glycols comprises adding aqueous potassium permanganate to polypropylene glycol having a molecular weight from 1,000 to 4,000, in an amount such that from 0,15 to 2,8% by weight, based on the weight of the polypropylene glycol of potassium permanganate is present, heating the resulting solution in the temperature range from 20 DEG C. to 90 DEG C. under reduced pressure for a period of time sufficient to remove the water present by distillation, removing the insoluble material formed and recovering the treated polypropylene glycol.  The heating is preferably effected under an inert atmosphere, e.g. nitrogen, carbon monoxide or carbon dioxide.  Elastomeric polyurethanes are produced by reacting the treated polypropylene glycol with excess polyisocyanate, e.g. m- and p-phenylene diisocyanates, 2,4- and 2,6-toluene diisocyanates, 2,3,5,6-tetramethyl-p-phenylene diisocyanate, o-, m- and p-xylene diisocyanates, 4,41-diphenylene diisocyanate, 3,31-dimethyl-4,41-diphenylene diisocyanate and diphenylmethane-4,41-diisocyanate.  Examples describe the treatment according to the invention of various polypropylene glycols, the products being reacted with the diisocyanates listed above to produce elastomeric polyurethanes, 1:4-butanediol being the specified cross-linking agent.

Title: Remote indicating systems
IPC: B61L7/08
Filed: 1959-08-17
Abstract: 875,181. Electric selective signalling systems. GENERAL RAILWAY SIGNAL CO. Aug. 17, 1959 [May 27, 1958], No. 28015/59. Drawings to Specification. Class 40 (1). In an electrical remote indicating system for registering at a central station indications of variable conditions at a plurality of field stations remote from said central station and connected thereto over a communication channel, each field station is adapted to transmit a distinctive signal to the central station upon the occurrence of a change of condition at said field station, the central station is responsive to such signals to change the transmission conditions in said channel, and each field station is responsive to the change in transmission conditions in said channel to lock itself out of communication with said central station if no change in condition has taken place at such field station. In the quiescent condition of the system described each field station transmits a distinctive frequency to the central station and the central station both transmits a characteristic frequency to all the field stations and also applies a D.C. bias to the transmission line. When a change of condition occurs at a field station it ceases to transmit its characteristic frequency which absence is detected by the central station and causes the central station to cease to transmit its characteristic frequency and this absence causes firstly all the other field stations to be locked out (i.e. prevented from initiating a transmission) and secondly electro-mechanical oscillators to be started at the central station and at the field station where a change in condition has occurred. These oscillators advance counters at the field station and central station and result in the serial transmission, from the field station, of the conditions of a plurality of contacts thereat, and the registration of this data on relays at the central station. At the end of a cycle of the counters the quiescent conditions are restored and any other field station can initiate a transmission. Two or more field stations can make simultaneous transmissions providing they are initiated simultaneously. The central station can transmit data to a selected field station by means of a D.C. system which operates as follows: to initiate a transmission the central station first reverses the polarity of the D.C. bias applied to the transmission line, which causes oscillators at each field station to advance counters thereat (different to those used for field station transmissions), then the central station transmits a call word which selects one of the field stations, and finally it transmits the data. The detailed description employs conventional electromechanical relay techniques and relates to the locking-out of field stations and to the construction of the field station transmission counters. The way in which data is actually transmitted is not described in detail.

Title: Improved method of coating the interior surface of steel tubes or the like
IPC: B05D7/22
Filed: 1933-10-11
Abstract: An iron or steel pipe or tube, while heated, and containing a quantity of bitumen in a fluid state in the bottom, is maintained substantially horizontal, and rotated slowly, e.g. by rollers to lap or spread the bitumen in successive layers into a uniform coating. The speed of rotation is insufficient to subject bitumen to any appreciable centrifugal force.  The bitumen may be introduced into the tube before, during, or after heating, e.g. by dipping, end rings being employed, if desired, to retain a sufficient quantity.  After the initial setting of the bitumen, the end rings may be removed, and the rotation of the tube may be continued while a cooling medium, e.g. a water spray, is applied to the exterior until the bitumen solidifies.  Heating means such as a gas torch may be passed through the tube to soften temporarily, and so smooth, the surface of the bitumen coating.  A small quantity of a filler such as slate dust or kieselguhr may be added to the bitumen.  According to the Provisional Specification the tube may be coated in the cold state.
