IPC: D03J1/14
Filed: 1920-04-30
Abstract: 168,361. Ward Bros. (Blackburn), Ltd., and Dobson, W. April 30, 1920. Healds and reeds, threading.-Relates to apparatus for selecting and separating warps preparatory to their being drawn through the healds and reed, and of the type described in Specifications 29477/13 and 104,036 wherein the warp threads are selected by a needle one by one, and are transferred thereby to a toothed separatorcomb. Selector-mechanism, which is stopped automatically when a number of separated warp threads have accumulated, and is re-started when these threads are removed from the comb, is employed in combination with a pedal j, Fig. 1, extending -across the machine and connected to a lever k carrying a bowl acted on by an adjustable cam e on a power-driven shaft a, whereby the machine may be worked by foot or power at the will of the drawer-in. The lever k is connected by lever mechanism to the vibratorbar q for operating the selector-mechanism, and by stopping the power-driven shaft a with the cam e in its highest position, ,the treadle may be operated by foot to actuate the selectormechanism, whilst, by holding the treadle down, the selector-mechanism may be stopped with the shaft a running. The cam-shaft a may be driven by belt gearing. Fast and loose pulleys and a belt-shifter may be provided; or an electric motor may be used controlled by a switch. The triplever r, Fig. 3, serving to make or break the driving connection between the vibrator-bar and the selector-mechanism, is pivoted to the part r<3>, which carries the selector-mechanism, instead of being pivoted to the part r<1> connected to the vibrator-bar as described in the before-mentioned Specification 104,036, and the driving-connection is arranged to be broken with the comb r<4> in a retracted position. The trip-lever moves about an inclined pivot so as to act by gravity, and the feeler-lever s is spring-controlled. A rotatable eccentric boss t is fitted to the base-plate of the selector-carriage for varying the distance in which the part can move. The healds and reed mav be carried on a bar supported by links slidable along a fixed flat bar supported in end frame brackets. According to. the Provisional Specification, the driving-motor may be on the selecting carriage.

Abstract: 252,162. Gustafsson, E. G. T. May 16, 1925, [Convention date]. Extracting; purifying and refining.-In a process for producing iron wherein a metalliferous charge is melted, if desired after reduction of the said charge, in an electric furnace, after a charge has been melted the metal and slag are tapped, and before the electric current is turned on a suitable quantity of slag from the tapping or another slag in a molten state is introduced into the furnace to protect the bottom of the latter at the beginning of the next melting operation in the furnace, the empty furnace being fettled if desired before the introduction of the slag. The metals and slag are tapped into a ladle or chamber provided with an overflow by which the slag is allowed to flow into a separate ladle &c. for introduction into the furnace. If the slag when transferred to the ladle tends to solidify it may be heated and refined by means of a current from an electrode and a graphite block, iron rod &c. disposed in the bottom of the ladle. If the furnace is a tiltable one, it may be provided with a lateral tapping opening and the metal and slag may be tapped into a removable ladle from which the metal is tapped off through a bottom tap hole or holes provided with a nozzle and stopper. The molten slag is introduced into the furnace through a suitable opening along an iron rod &c. extending downwardly to the bottom of the furnace. The iron, steel &c. may 'be produced directly from the ore melting in the electric furnace a charge consisting of a mixture of finely divided ore and finely divided carbonaceous material compressed into briquettes or lumps by the use of a binding agent, the briquettes &c. being dried.

A fuel element as described in the parent Specification has a set of parallel transverse fins provided on each of the portions of the sheath disposed on the concavely curved portions of the fuel rod, the fins of each set being arcuate in shape and their central surfaces forming semicylinders, the axes of which are parallel to each other and at an acute angle to a plane perpendicular to the longitudinal axis of the element. The fins are made by fixing the sheathed rod on a milling machine provided with a cylindrical milling cutter (Fig. 5, not shown) in a position such that the axis of rotation of the cutter intersects the axis of the sheathed rod, rotating the cutter arid simultaneously moving it along its axis of rotation in order to cut into the sheath, in one single passage, a sub-channel between two successive fins, withdrawing the cutter, relatively displacing the sheathed rod and the cutter in a direction parallel to the axis of the rod by an amount corresponding to the distance between two fins, and repeating the machining operation and the displacement parallel to the axis of the rod. 'The rod may be of pure uranium or uranium alloy and the sheath of a magnesium-zirconium alloy of low zirconium content. The element is supported in a channel through which coolant flows by means of four centring members (Fig. 3, not shown) arranged in planes passing through the common axis of the element and of the channel. The centring members may extend the length of the element or they may consist of a series of separate spiders. The coolant is caused to flow in two contra-rotating helical streams between each pair of centring members.
