A continuous wet-spinning method for producing a useful filamentary material, such as multi-filaments or a tow, from a spinning solution of an acrylonitrile copolymer in an aqueous saline solvent consisting essentially of zinc chloride. In this method, an aquagel filamentary material obtained by spinning the spinning solution is taken up from an aqueous coagulating bath, continuously stretched in water and continuously dried so as to form a dried filamentary material having a moisture content of...

Curved pipes are thermally insulated by wedge-shaped annular elements of resin-bonded glass or other mineral fiber in which the fibers are perpendicular to the axes of the elements, so that these are axially compressible. The elements are pressed together into face-to-face contact along the pipe. They may be made by stamping cylinders out of fiberboards and cutting each cylinder along a plane inclined to the axis.

A device for rapidly transferring energy from a superconductive storage device to a utilization device. A first switch is coupled across the superconductive device and a second switch is coupled across a secondary of a transformer comprising the superconductive device and the secondary. The utilization device is coupled across the secondary in parallel with the second switch.

A process in which a quaternary vinyl pyridine salt may be produced and then polymerized directly without the need for any isolation stage is disclosed. The process involves the replacement of the conventional non-aqueous solvent for the reaction by water; the vinyl pyridine and water are mixed, a quaternizing agent is added to the mixture and the mixture heated to form a solution of the quaternary vinyl pyridine salt. The solution so produced is then directly amenable to polymerization without ...

A ventilating apparatus for mounting in a roof and comprising a central shaft for exhausting spent air from the ventilated room, a surrounding annular duct divided in an upper and a lower section by means of a transverse partition wall secured to the periphery of an exhaust blower wheel located in the central shaft. Separate blower vanes are secured to the upper and lower face of the partition wall for delivering fresh air from the ambient and recirculated air from the room, respectively, to a m...

The 1-menthol may be utilized in perfumes, medicines, etc. 7 Claims, No Drawings

A method of drawing a tubular thermoplastic resin film comprising transporting said tubular film onto a mandrel which has a polyangular conical shape, causing the uniform occurrence of necking initiation points around the circumference of said film by drawing said film around said mandrel, and continuing to draw said film by the action of fluid pressure exerted within said film after said film has passed over said mandrel.

A process for producing tetrachloroethylene comprising passing a gas stream of ethylene over a catalyst composition of cupric chloride and an inert material at a temperature in the range of 400 to 525.degree. C. and at a flow rate of less than 5 cc of gas stream per minute per gram of cupric chloride. 6 Claims, No Drawings

A first and second magneto-electric converting films, comprising for example, Hall elements, are vapor deposited onto a first and second highly permeable magnetic substances independently of each other. The resulting configuration is aligned so as to correspond with each track of a magnetic tape. A desired number of the magneto-electric converting films can be positioned parallel with each other. The resulting magnetic head with the multiple magneto-electric converting films is capable of produc...
