Title: Improvements in apparatus for clearing or cleaning yarns
IPC: B65H63/06
Filed: 1932-02-15
Abstract: 384,843. Yarn-clearers. MARSH, J. H., Hazel-dene, St. Austell Road, Alexandra Park, Manchester. Feb. 15, 1932, No. 4377. [Class 120 (ii).] Apparatus for clearing yarns comprises a rotatable shaft 9 bearing a plurality of fixed circular clearer knives 6, a further plurality of clearer knives 7 each of which embraces the shaft and is coaxial with a clearer knife 6 to form a pair, means external of the shaft for maintaining the knives in yarn-clearing relation and means for effecting relative adjustment between the shaft and the external knife holding means. The shaft 9 carries a collar 11 and pinion 10 by which it is rotated through suitable gearing from the headstock of the machine, and the end of the shaft 9 passes into a bearing in the frame 5 and carries collars 12, 13 which embrace a ball race 14 and a compression spring 15 which maintains the collar 13 against the ball race 14 and the shaft 9 against a thrust ball 16 in a recess in a screw plug 17. The shaft 19 secured in the frame 5 by a screw 19a carries brackets 20 which take into peripheral grooves 23 in the knives 7, and either prevent or permit rotation of those knives. If desired the adjustable bearing may be arranged at the end of the shaft 19 instead of the shaft 9. In a modification, each knife 7 may be rotated from the shaft 9 by means of a driving collar 25 pinned on the shaft and housed in a recess 24 in the knife which is loosely mounted on the shaft. This collar is formed with a slot in its flange 26 which engages with a grub-screw 27 in the knife 7. A cover 28 screwed over the recess 24 forms the central plate of a ball race, the outer plate 29 and inner plate 30 maintaining the balls in position and being themselves held in position by screws 32 passing through the plates 29, 28 into the plate 30. Recesses 33 in the brackets 20 house springs 35 surrounding these screws and abutting against their heads 36 and the end of the recesses. In another modification the knives 7 may be rotated from the knives 6, for example, by metal pegs projecting from the knives 6 engaging in recesses in the contiguous faces of the knives 7, which are held in position either by the means shown in Fig. 2-the driving collar 25 and screw 27 being omitted-or by engagement of the bracket 20 in a groove in the knife 7 to permit rotation thereof. By making the shafts 9, 19 of the same cubic content and of metals with the same coefficients of expansion under heat, variation in the width of the slit x due to variations in temperature are avoided. Specification 189,302, [Class 120 (ii), Spinning, twisting, &c.], is referred to.

Abstract: 866,988. Fluid-pressure servomotor control systems. SZYDLOWSKI, J. Feb. 12, 1958 [Feb. 20, 1957], No. 4641/58. Class 135. [Also in Group XXVI] A fuel feed system for a turbojet engine 18 comprises a fuel metering valve 11 actuated by a servo-device comprising a piston 19 and speed-sensitive control valve 24 with a temporary followup action, and means comprising a valve 57 actuated by a bellows 61 subject to the delivery pressure of the compressor of the engine for limiting the speed at which the metering valve is actuated. Fuel is delivered by a pump 1 and conduit 5 to a valve 13 which is subject to the pressures on either side of the metering valve 11 so as to control the pressure difference across the latter, this pressure difference being governed by the force exerted by a loading spring 14 which is adjusted by a servo-piston 68 under the control of a valve 64 which is actuated by a bellows 74 subject to the total head pressure at the inlet to the compressor. A rack and pinion 72, 71, a cam 70, and a lever 69 constitute a follow-up connection between the servopiston 68 and the valve 64. Fuel leaving the valve 13 passes to the metering valve 11, thence to a valve 16 actuated by a throttle control lever 36 and finally to the burners 17 of the engine. The lever 36 also acts on an adjustable loading spring 32 of the valve 24 for setting the speed of the engine. The temporary follow-up between the servo-piston 19 and the valve 24 consists of an adjustable restriction 23, a spring- loaded piston 20, and connections from each side of the pistons 20 to opposite ends of the valve 24. This arrangement is described in Specification 860,283. The arrangement for limiting the speed at which the metering valve 11 operates consists of the member 57 which is rotated by the engine and controls the outlets from conduits 54, 55 through one of which the servo-piston 19 is exhausted when the valve 24 is moved from its neutral position. The degree of obturation of the outlets from the conduits 54, 55 is determined by the bellows 61. The valve 24 is rotated by an oil-driven turbine 53 to reduce static friction. A small pump (not shown) for engine starting is fed through a valve 80 which is opened for a limited period by an electric relay 81.

Vacuum tubes.-A grid electrode for a thermionio valve consists of a number of cross-members formed integrally with one or more supporting or connecting members, and bent alternately so as to lie on opposite sides of a plane and so form an enclosure to accommodate another electrode. 'The grid may be formed by stamping a blank 33, Fig. 2, with slots 34, and bending out alternate cross-members 35, 35' in opposite directions to form an enclosure for the filament as shown in Fig. 1. The edges 36, 37 of the blank may be bent to trough shape for securing to supports 27. In a modification, the lengths of the cross-members increase from the top to the bottom of the grid, so as to provide an enclosure uniformly spaced from a V-shaped filament. A cylindrical grid may be formed by bending out the alternate cross-members to semicircular shape. The cross-members may be twisted about their longitudinal axis so as to vary the effective area of the grid. According to the Specification as open to inspection under Sect. 91 (3) (a), a cylindrical grid may be formed by stamping a blank as shown in Fig. 10 (Cancelled) to leave longitudinal and vertical members 58, 57, and bending the blank so that the ends 61, 62 overlap. Projections 65 on the ends may be secured to supports. In another construction two blanks are used, and the crossmembers of each blank are bent outwards so as to lie in a common plane. The blanks are clamped together to form an enclosure similar to that shown in Fig. 1. This subject-matter does not appear in the Specification as accepted.
