Abstract: 947,561. Wire packages. AMERICAN CHAIN & CABLE CO. Inc. July 17, 1962 [July 21, 1961; June 22, 1962], No. 27420/62. Headings B8C and B8M. [Also in Divisions A4 and D1] A package (Fig. 3) of coiled wire comprises an inner core 30, several layers of helically wrapped wire on said core, and circumferential containing means applied about and securing each wire layer and being adapted to tear away when the wire is pulled forcibly from the package. The core 30, a sheet of paper about 0.04 inch thick, is wrapped tightly around a collapsible drum 10 (Fig. 1), formed of a plurality of segments or staves and mounted on a spindle 11. There is a hole in the core, preferably in the longitudinal seam 1 inch from the end, and overlying a hole in the drum for the insertion of the free end of the wire. The spindle 11 also drives through a gear transmission 16, which reverses the sense of rotation, a yoke 19 on which is mounted a freely rotatable reel 23. As the yoke rotates and the wire is wound from the reel 23 on to the core 30 by means of the transversely moving guide 27, the wire receives a back twist of one turn for each convolution on the core 30 to compensate, in advance, for the twist produced when the package is overend unwound. The transmission 16 may include automatically variable speed controlling means to compensate for the increase in diameter of successive layers of wire. The apparatus stops at the end of each traverse of the guide 27 so that a layer 34 of paper can be placed over each layer of wire at each end. In addition, or alternatively, the paper layer may be placed between the ends of the package (Fig. 6, not shown). The package may have end flanges connected by an outer cylinder or by tie rods, in which case the wire is withdrawn through an aperture 62 (Fig. 6), in the flange.

Title: Process for recovering allene from mixtures by a sorption-desorption technique
IPC: C07C7/156
Filed: 1966-06-20
Abstract: Allene is recovered from C3 hydrocarbon mixtures containing allene, methyl acetylene, propylene and propane by a process comprising (a) contacting the mixture with an active particulate cuprous halide having a porosity of above 10% (of the total volume of a particle) as 550 to 10,000 <\>rA pores at a temperature and pressure sufficient to form cuprous halide complexes with allene and methyl acetylene; (b) subjecting the complexed cuprous halide to conditions such that the partial pressures of allene and methyl acetylene are below the dissociation pressure of said complexes to form an allene-methyl acetylene concentrate free of propylene and propane; and (c) recovering the allene and methyl acetylene therefrom, e.g. by fractional distillation.  Step (a) may be carried out at a temperature of - 50 DEG  to 40 DEG  C. and a pressure of 0.3 to 15 atmospheres absolute; and step (b) at 30-100 DEG  C. and a pressure of 0.3 to 15 atmospheres.  In a preferred embodiment the complexes obtained in (a) are partially dissociated before the dissociation (b) to obtain an allene-methyl acetylene concentrate having a higher concentration of allene; this partial dissociation may be carried out at 20-60 DEG  C. and a pressure of 0.3 to 15 atmospheres. The complexing step (a) may be conducted in the vapour phase at a temperature within 17 DEG  C. of the dew point of the hydrocarbon mixture or in the liquid phase employing less than the stoichiometric amount of Cu2Cl2 for a time sufficient to form a complex with allene.
