Title: Improvements in or relating to receivers for materials, such as artificial silk and other artificial filamentary products, particularly for the spinning process
IPC: B65H75/18
Filed: 1933-11-17
Abstract: A receiver for artificial silk and other artificial <PICT:0421140/IV/1> <PICT:0421140/IV/2> <PICT:0421140/IV/3> <PICT:0421140/IV/4> <PICT:0421140/IV/5> thread-like structures in the spinning process is constituted by a rim 1 having a smooth, apertured winding trough, the lateral limiting walls of which also serve for driving the rim at its periphery.  The receiver which may be of lacquered aluminium, acid or lye proof steel, ebonite or a similar artificial material is of a cross section having a flat middle portion 2 which joins the raised marginal portions 4 by means of outwardly flared sides 3. The marginal portions 4 are formed by beading inwardly or outwardly the material of the receiver and serve as stiffening means.  The thread material is shown at 5.  The middle portion 2 may be slightly concave.  If desired, the cross section of the trough may be V-shaped, the edges either merging directly into the driving-rim 4 or vertical sides being provided leading up to the driving-rims, or the trough may be semi-elliptical in cross section, or may have a slanting bottom with vertical sides leading to the driving-rims.  The beads 4 may be replaced in some cases by rubber rings mounted on each side of the receiver.  In all cases the trough is provided with perforations 7.  The width of the traverse of the means laying the thread in the trough may be constant or variable, and the thread layers may be parallel with the bottom of the winding trough or in the case where the trough has a V-shaped cross section may be parallel with one side of the V.  The receivers are mounted for driving on rollers 8 on shafts 9, driving the receivers at their peripheries.  The receivers may be pressed snugly one against the other for after treatment processes, especially when rubber rings are provided at the sides for driving rims.  A modified form of receptacle shown in Fig. 13 is particularly adapted for co-operation with similar receptacles to form a drum as shown in Fig. 11.  The distance between adjacent winding troughs on this drum corresponds with the distance between adjacent spinning nozzles.  At each end of the drum a rim 51 of larger diameter than the inner ribs 4 is provided, and at spaced intervals along the drum larger ribs 52 are provided.  These ribs 51, 52 serve for driving the drum by means of rollers 8.  The drum may be inserted in an after treatment vessel, the ends only needing sealing with respect to the vessel.

Abstract: 989,386. Waveguide filters. MARCONI CO. Ltd. June 28, 1963 [Aug. 24, 1962], No. 32632/62. Heading H1W. A waveguide filter comprises one or more resonant lengths defined by conductive posts P extending between the broad walls of a rectangular waveguide, and tuning means comprising at least one conductive member TM, e.g. a screw, extending adjustably from a narrow wall towards one of the posts. The filter shown comprises three half-wavelength cavities defined by four posts P, the outer posts being thinner than the inner posts. The resonant lengths are chosen to have optimum values at the upper frequency limit of the tuning range and the diameters of the posts to have optimum value at the lower frequency limit. The filters are tuned to the lower limit when the inner faces of the screws TM are flush with the inside of the guide. The diameters of the screws are as large as the dimensions of the waveguide will permit. Final adjustment may be made with the capacitative tuning screws TS. The invention may also be applied to the type of filter using a number of half-wave resonant lengths spaced by quarter-wavelength sections (Fig. 3, not shown).
