Patent GB-397114-A (GB)
Title: Improvements in or relating to the manufacture of artificial filaments and the like
IPC: D01D5/04
Filed: 1932-02-10
Abstract: <PICT:0397114/IV/1> <PICT:0397114/IV/2> When dry spinning artificial filaments &c., evaporative medium is supplied at the region of the spinning nozzle through a pipe or jet 27 which can be brought to a position at one side of the nozzle and close to the group of filaments, while the air pipe or jet can be moved away without disturbing the spinning operation so as to leave free access to the filaments.  For this purpose the pipe 27 may be mounted on a swivel 29 arranged either horizontally or vertically, and the connection may be such that movement of the pipe away from the filaments cuts off the supply of air; and it is convenient to mount the pipe on the door by which access is given to the spinning nozzle.  Two or more of the pipes 27 may be employed with one spinning nozzle.  The jet 28 through which the air is actually delivered, preferably projects the air in a thin flat stream transversely to the filaments, and for this purpose it is convenient to employ nozzles of the gas-burner type. The current of air may be induced by suction, although a pressure supply created as by means of a pump, fan &c., is preferred; and the air may be heated by leading the supply pipe through the spinning cell or adjacent to the means for heating the cell.  The air supplied through the movable pipe or jet may contain gases or vapours introduced, for example, from a header to each of the pipes leading to the spinning nozzle, and the air in the cell may move in the same direction as the filaments or in countercurrent thereto and it may be exhausted at the region of the spinning nozzle or wholly or in part at other points in the cell. Specification 325,233, [Class 2 (ii), Cellulose &c.], is referred to.

Patent GB-827016-A (GB)
Title: Improved method of producing metal coated, non-metallic particles
IPC: C23C18/52
Filed: 1957-02-06
Abstract: Non-metallic particles are coated with Os, Rh, Ru, Ir, Pt, Pd, Au, Ag, Cu, As, Pb, Sn, Ni or Co by being dispersed in an ammoniated solution containing a soluble compound of one of said metals, and reacting the solution with a reducing gas at a temperature above 200 DEG F. and under a positive partial pressure of reducing gas.  The resulting powder may be compacted to form high temperature alloys, cermets and ceremels.  The non-metallic particles may be oxides, such as those of Al, Be, Th, Zr, Ti, Si, Ce, Cr, U, V; oxide combinations with calcium oxide such as the Spinel group; sulphides, such as those of Ce, Th, U; and carbon in its crystal forms.  The ammoniated solution may be aqueous or other solvents such as alkanols, ethers, ketones and esters may be used.  The soluble compound of the metal may be the sulphate, chloride, nitrate, carbonate, fluosilicate or acetate.  Hydrogen is preferred as the reducing gas; other gases that may be used are carbon monoxide, methane, producer gas and natural gas.  The reaction is preferably conducted at a temperature of 200 DEG F.-500 DEG F. and under a partial pressure of reducing gas of 4-35 atmospheres.  Prior to coating with metals other than Ag and Cu, the refractory particles should be impregnated with an agent which has a higher reducing potential under reducing conditions than the reducing gas employed so that the metal deposits on the particles as an adherent coating; suitable agents are ferrous, thorous, cerous, manganous and chromous compounds, hydrophosphites, hydrosulphides, hydrosulphites, hydrazine, formaldehyde, phosphites, cyanides, formates, thiosulphates, nitrites, sulphites and sulphides. Specification 824,092 is referred to.

Title: Improvements in electric control systems for transmitting movements synchronously
IPC: G08C19/38
Filed: 1927-02-15
Abstract: 275,495. Granat, E., and Compagnie des Forges et AciÚries de la Marine et d'HomÚcourt. Sept. 28, 1926, [Convention date]. Addition to 267,100, [Class 38 (iii), Electric motor control systems &c.]. Electric selective distant control systems.-The system described in the parent Specification, whereby a number of distant motors are kept in synchronous rotation with respect to a rotating transmitter machine by placing one of the receiver motors close to the transmitter machine and coupling the two mechanically so as to maintain the initial difference of phase, is applied to produce definite follow-up or repeating movements of apparatus controlled by gyroscopic compasses or other instruments of small power. As shown in the drawing, movement of a gyroscope G with respect to a phantom ring S displaces a set of potentiometer contacts connected to the transmitter machine T, which is kept in continuous rotation by an auxiliary motor. One receiver motor R<1> is coupled to transmitter brushes whereby the initial difference of phase is maintained as long as the gyroscopic displacement remains uncancelled; another receiver motor R<2> is mechanically coupled to the phantom ring so that as it rotates it gradually cancels the initial displacement. All the receiver motors thus stop after running distances proportional to the movement of the gyroscope. Specification 216,154 is referred to.
