A hollow filament bundle for use in a separator module is made by rotating two co-axial spiders 24 and 28 and looping a continuous hollow filament which is fed from a package 32 alternately around the arms 26 and 30 of the two spiders. This is done by means of a guide 40 which is reciprocated between the two spiders by a screw threaded shaft 34 which is rotated first in one direction and then the ...

A composite electrode having a structural electrode member with at least a portion of one surface of the electrode member constructed from a continuous matrix of an anodically passivatable metal infiltrated by a metal capable of forming an electroconductive oxide and having the infiltrating metal at the electrode surface oxidized such that an electric current path is provided through the oxidized ...

The specification relates to a supporting arm capable of being turned freely itno different positions, which is made up of at least two straight sections articulated to each other, such a section containing a parallelogram formed by articulated arms in such a way that the ends of the same description of the two long parallel articulated arms (8, 6) of the parallelogram are articulated to a common ...

A scanning electron beam computed tomography scanner includes means defining a vacuum chamber (16), means (21, 22) for producing a space-charge limited electron beam (24) at one location in the chamber (16) and for directing it to a second location therein, and an elongate target (26) of the type which produces X-rays as a result of the impingement thereon by the electron beam (24). The scanner al...

A hopper feed apparatus for the powder hopper of a powder reinforcing machine, to keep the hopper and its supply conduit free of clogged powder, the apparatus comprising of an arrangement of springs attached to the top of the hopper on the inside thereof, which springs extend downwardly to a common point near the discharge orifice, to where they are attached to a line which extends through the con...

A battery grid pasting machine has an endless steel conveyor belt (80) for advancing grids beneath a paste hopper (132). The lower end of the hopper is closed by an orifice plate (170). The top run of the belt is supported by a vertically adjustable roller (82) directly beneath an orifice slot (194) in the orifice plate (170). A guide assembly is provided for advancing the grids in a downwardly in...

The compressed-air pipe (20) leading to the splicing chamber (1) of the yarn splicing device encloses a humidification tube (30) which opens into this compressed-air pipe and which proceeds from a container filled with liquid (24) in which the liquid level is below the aperture (5) of the splicing chamber (1).
