Title: Improvements in machinery for and method of opening, cleaning and subsequent treatment of textile fibrous material
Inventor: HUNTER WILLIAM ALDRED
IPC: D01G9/00
Filed: 1955-08-23
Abstract: 807,515. Opening and blending fibres. T.M.M. (RESEARCH) Ltd. Aug. 9, 1956 [Aug. 23, 1955], No. 24237/55. Classes 120(1) and 120(3) A machine for opening and cleaning fibrous materials comprises two parallel feed trunks A, B; a toothed rotary beater cylinder 14, co-operating with dirt-extracting means 15, 16, associated with each feed trunk; means for forming material fed. through each trunk into a partially compacted sheet, means for presenting the sheet edgewise to the toothed surface of the associated cylinder 14 and means for feeding it forward so that it is progressively disintegrated and carried past the dirt-extracting means, mechanical and/or pneumatic means for stripping the cleaned fibres from the cylinders; a reception chamber 17 located between cylinders 14 into which the stripped material is deposited; and a delivery outlet 19 into which opened fibres are conveyed from chamber 17. As shown, the sheet forming and feeding means consists of a fluted roller 13, which may be spring loaded, co-operating with the curved part 111 of a feed plate 11. A deflector 20 separates two air inlet ducts 21, 22 providing induced air streams Z which strip fibres from the cylinders 14 into chamber 17. In other embodiments, the fibre sheet is fed to the beater cylinder by a roller co-operating with a set of spring-loaded pedals or by a pair of contrarotating rollers. Material may be delivered to the trunks by cage or other condensing apparatus, feed to the, trunks being controlled to photo-electric or other means sensitive to the head of material in the trunks. The delivery ducts 19 from a number of units may deliver material to a common point. Separate ingredients may be fed to separate trunks, a desired blend being obtained by controlling the rates of supply from the trunks, e.g. by varying the speed of rollers 13.

Abstract: 844,228. Transmission systems. WESTERN ELECTRIC CO. Inc. Aug. 1, 1958 [Aug. 7, 1957], No. 24853/58. Class 40 (4). In an arrangement for correcting phase distortion in communication signals received over a line 8 or other medium of limited frequency range, a test signal received after transmission is recorded on a magnetic drum 20 and timespaced reproductions thereof are used subsequently to modify the received communication signals. Signals received over the line pass through an amplitude-equalizer 10, and, with the switch 12 in the upper position, the test signal, which as transmitted is of sharp waveform and short duration, is recorded on a drum 20 during one revolution thereof. Reading heads 31 ... 38 are spaced around the drum so that successive reproductions are delayed by a time T = 1/2W, W being the highest frequency transmitted by the line, and these are fed respectively to multipliers 41 . . . 48, which, when the switch 12 is in the lower position, also receive the communication signals, and the products pass to integrators 51 . . . 58 which may be simple low-pass filters. The signals stored in the integrators are released in succession by transistor or other switches 61 ... 68 which are controlled by a pulse once per rotation of the drum from a battery 60 through a tapped delay line 70, the tappings corresponding to intervals of the time T mentioned above, and the combined output passes by way of a low-pass filter to the receiver 80. Instead of a number of reading heads, the drum 20 may have a single reading head in conjunction with a tapped delay line.

Title: Improvements in stop-motion devices for spinning frames
IPC: D01H13/18
Filed: 1926-10-11
Abstract: 261,721. Eclipse Machine Co., (Assignees of Garey, J. P., and Hasbrouck, L. B.). Nov. 18, 1925, [Convention date]. Delivery, stopping; thread-guides. - In a spinning-frame provided with a series of roving breakers 3, Fig. 4, in advance of the drawing rolls D, and power-driven members which actuate the breakers when a trigger which normally engages the roving is released, each trigger consists of a thread guide 9, Fig. 2, on a nearlybalanced lever which, on breakage of the roving, turns in a vertical plane into the path of one of two reciprocating bars 1, 1<1> and is turned thereby further in the same direction to move a connecting member, which actuates the breaker. A bar 61 carried on brackets 62 pivoted to brackets 63 is provided on each side of the machine for raising the guides J when it is desired to doff. The bars 1, 1<1> are driven oppositely from the main shaft by a belt 13, shafts 12, 14 and cams 16, 16<1> under the control of springs 19, 19'. The pulley wheel 22 is provided with a clutch 23 which is automatically opened by the shifter bar M of the stop mechanism through the lever 25 and actuator plate 24 on stopping the frame, and cannot be closed again until after the machine has started. It may be closed manually by the handle 27. The yarn clamping devices 3, Figs. 4 and 13, comprise a roughened cylinder 5 eccentrically mounted on a spindle 39 and turnable thereabout by a crank 48. The yarns are fed over a flat surface 42 and under the member 5 and normally pass clear thereof. Each controlling mechanism 4 comprises a lever 8 pivoted at 28 and formed of two arms 29, 30 normally locked together and held by the yarn so that the projection 32 is clear of the end of the short arm 33 of the actuating member 7. Each lever 8 is provided with a wedge-shaped cam 34, while the members 1, 1<1> are provided with upwardly-projecting knives 35 which normally pass clear of the cams 34, Figs. 4 and 10. The actuating member 7 comprises separate arms 33, 53 pivoted at 52, the longer arm 53 normally lying flat on the table B. On breakage of a yarn in or beyond the drawing rolls, the lever 8 turns under the action of gravity to the position shown in Fig. 5; the cam 34 is thereupon forced laterally by the knife 35, Fig. 11, the lever 8 tilts further and jerks the member 7 upwards into contact with a plunger 49, Fig. 4. This plunger is raised and turns the crank 48, thereby clamping the yarn between the cylinder 5 and the surface 42. The projection 32 passes under the arm 33 thus permitting the member 7 and plunger 49 to resume their normal positions. The lever 8 is held in its raised position, the cam 34 being outside the path of the knife 35, until the operator having released the yarn and pieced the broken ends presses down the arm 29 to reset it.
