[Also in Divisions B5 and C3] A foamed filament useful in brush-making is made by continuously extruding a propylene homopolymer or a propylene copolymer containing at least 50% by weight propylene monomer polymerized therein together with a foaming agent to form a foamed filament having a crosssection of at least two lobular projections extending symmetrically or substantially symmetrically from a common centre portion; cooling said extruded filament in an inert cooling medium; raising the temperature of the cooled filament to a temperature below 110C.; introducing the heated filament into an orientation zone and effecting orientation at an orientation ratio of less than 4: 1 to produce a filament having repeated unorientated and oriented portions adjacent to one another along its length; and introducing the resulting filament to a heated annealing zone to heat said filament for a sufficient period of time to effect an annealing thereof. Preferably, the temperature of the orientation zone is in the range of 100-110C., and the temperature of the annealing zone is in the range of 138-154C. The preferred range of orientation ratio is from 2:1 to 4: 1. Foamed synthetic filaments so made have a homogeneous cell structure, a cross-section as above described, and repeated unoriented and oriented portions adjacent to one another along their lengths, said unoriented portions having a larger cross-sectional area than the oriented portions, the aggregate lengths of the oriented portions being at least 40% but not more than 80% of the total length of the filament, the filament having a specific gravity not exceeding 0.80. Preferably, the smallest dimension of the cross-section of the unoriented and oriented portions is from 0.0.15 to 0.150 inches from the unoriented portion, especially 0.020 to 0.050 inches, and for the oriented portion, from 0.005 to 0.075 inches, especially from 0.010 to 0.040 inches. Such filaments may possess unit lengths for the unoriented portion ranging from 1/16 inch to ¥ inch, while the unit length of the oriented portion may range from # inch to 2 inches. The aggregate length of the oriented portion generally comprises at least 40% but not more than 80% of the total length of the filament, and preferably at least 50% and not exceeding 75% of the total length. The filament may be made from isotatic polypropylene, which is defined as polyproylene comprising crystallisable isotactic molecules and up to 15% of amorphous, non-crystallisable macromolecules. Copolymers of propylene and ethylene may alternatively be used.

Filed: 1974-08-07
Abstract: 1479687 Stranding conductors SIEMENS AG 7 Aug 1974 [7 Aug 1973] 34892/74 Heading H1A A plurality of groups of insulated conductors are formed simultaneously, each group comprising at least two insulated conductors stranded together, and are stranded to form a bundle with periodic actions being carried out to shift the positions of the conductors with respect to the stranding axis of each group, so that those groups have sections in "original phase position" and sections in "opposite phase position" (i.e. each conductor of a group at or near the centre of a length or section of "opposite phase position" has a phase displacement of about 180 degrees to that conductor at or near the centre of a length or section of "original phase position", the phase positions within each length or section being constant, or varying in the same sense), such that over the entire length of the cable for each pair of groups approximately equal sections are in the same phase position (i.e. both in original or both in opposite phase positions), and in differing phase positions (i.e. one in each phase position). A further group of at least two stranded conductors may be formed simultaneously with the other groups, and be stranded into the bundle, which further group is without the additional periodic actions. The groups may be pairs or star quads. The actions, which do not alter the sequence of star quads, may be carried out quickly within a lag length, or more gradually one action occurring at a time, and may be formed with a triangular or sinusoidal relationship between the angular displacement and the length of the group. The separation of sections with the different phases may be varied and 90 degree phases may also be obtained. The groups may be stranded to give alternate sections of left and right handed lay occurring at intervals of integral section lengths. The lay lengths may either be altered by integral lengths or by an odd number of half integral lengths. The apparatus for fabricating the bundle as outlined above is described.

Abstract: 445,213. Machine guns. TENNANT, W. J., 111, Hatton Garden, London.- (Werkzeug - Maschinenfabrik Oerlikon ; 155, Birchstrasse, Oerlikon, Z³rich, Switzerland) Dec. 6, 1934, No. 35094. [Class 92 (ii)] Relates to sear mechanism for retaining the breech block 2 in the open position against the action of the return spring 3, the sear 4, during continuous firing, being movable entirely out of range of the breech block. According to the invention, the sear is held in engagement with the co-operating abutment 9 on the breech block by retaining means, and the abutment face 11 is inclined from the front rearwardly so that on release of the retaining means the sear is thrown off the abutment by the force of the return spring. In the form shown in Fig. 1, two sears 4, pivoted at 5 to a frame 6 sliding against the action of a buffer spring 8, are held in engagement with the breech block abutment 9 by spring thimbles 16 bearing on a sliding release rod 13. On pulling the rod against the action of its spring 18, the thimbles are released for inward movement and the force of the return spring 3 acting through the inclined abutment faces 11 throws the noses 20 of the sears outwardly, springs 19 serving to keep them out of the path of the breech block until the rod 13 is released when the breech block can re-engage the sears. Fig. 6 shows a modification in which the sear 4 pressed outwardly by a spring 19 is retained in engagement with a pivoted resilient abutment 36 on the breech block by a cam 13a which is rocked in the direction shown to cause release of the sear by the pressure of the return spring on the abutment face 11. When the breech block returns to the rear after release of the cam 13a, the incline 10 on the abutment rides over the surface 12 on the sear and the abutment again engages the sear. The abutment is connected to a sleeve 40 sliding on the rear of the breech block against the action of the buffer spring 8.
