Patent CA-2061307-A1 (CA)
Inventor: CHANG FRANCIS H
IPC: G21F9/02
Filed: 1992-02-17
Abstract: A method for the recovery of carbon-14 (C-14) from a mixture of inert gas and carbon-12 (C-12), carbon-13 (C-13) and C-14 dioxides.  The mixture is cooled to a temperature below the solidification point of carbon dioxide to obtain solid carbon dioxide.  The solid carbon dioxide is volatilised to provide substantially pure carbon dioxide gas which is reduced to carbon monoxide gas by reaction with metal.  The carbon monoxide gas is cooled to obtain liquefied carbon monoxide.  A feed of the liquefied carbon monoxide is subjected to fractional distillation and a bottoms rich in C-14 monoxide and poor in C-12 monoxide is collected and a distillate poor in C-14 monoxide and rich in C-12 monoxide is removed.  The bottoms are oxidized to carbon dioxide rich in C-14 dioxide which is absorbed in a metal hydroxide solution and a carbonate salt rich in C-14 is obtained.

Title: Device for manipulating healds or drop wires in a warp-thread drawing-in machine
Inventor: BADERTSCHER MARKUS
IPC: D03J1/14
Filed: 1991-09-03
Abstract: Abstract The device serves to manipulate the healds or drop wires from their separation from a stack via the drawing-in of the warp threads up to the transfer to supporting members provided for arranging in a weaving machine  and  it  contains  holding means  (22,  24)  for accepting the separated healds or drop wires and for positively transporting them to a drawing-in station and a transfer station, positioning means (HP, SP) arranged in the area of the drawing-in station, and transfer means (39), arranged in the area of the transfer station, for transferring the healds or drop wires having a drawn-in warp thread to the supporting members.    Consequently, only a single type of manipulating means is required for manipulating the healds and drop wires from their separation up to the transfer to the supporting members. And that means a substantial reduc-tion in potential sources of error and thus  in the susceptibility to trouble. In addition, only two inter-faces  are  necessary:  one  leading  to  the  separating station and one at the transfer station leading to the supporting members.                             (Fig. 4)
