Title: Improvements in or relating to devices for cleaning and sorting pneumatically conveyed bulk goods
IPC: B01J8/00
Filed: 1955-08-10
Abstract: 779,589. Pneumatic separating. BUHLER, GEB. Aug. 10, 1955 [Aug. 11, 1954], No. 23075/55. Class 117 Granular material is conveyed in an air stream through an opening 1 and into a chamber 3, and the heavier and larger grains rebound from a deflector plate 2 and fall on to a pivoted flap 5 held by a spring, not shown. When the weight of material on the flap is sufficient the flap opens slightly and material falls as a thin stream 8 to escape from the apparatus through an air lock 18. A curved plate 4 causes a whirling of the material whereby lighter particles such as dust, chaff &c. in the air stream pass upwardly through a channel 7. Due to centrifugal force the fine particles flow along the outer wall of a curved part of the channel and are drawn through an adjustable suction opening 12, and pass through a channel 13 to an outlet 10 connected to a ventilator fan. The clean air stream continues downwardly and then passes through the falling stream 8 and carries away fine impurities upwardly through a channel 9 and the outlet 10. The outer wall 14 of the channel 9 is adjustable by a screw 19 to vary the channel width, and this provides a speed regulation of the air passing through the falling stream 8.

Title: Process and apparatus for heating and stretching filaments
IPC: D02J1/22
Filed: 1962-06-19
Abstract: 949,709. Heat-stretching filaments. MONSANTO CHEMICAL CO. June 19, 1962 [June 23, 1961], No. 23615/62. Heading B5B. Apparatus for heating and stretching filaments comprises means for supplying synthetic filaments capable of being molecularly oriented to a heat-stretch zone, means for withdrawing said filaments therefrom at a predetermined increased rate, and a yarn heater block disposed in the yarn path between the supply and withdrawal means said block having spaced apart walls defining a serpentine yarn passageway therethrough, so that opposite sides of the filaments passing through the passageway are sequentially heated by surface engagement with alternate surfaces of the passageway. As shown (Fig. 2), the yarn heater block may have an open-ended S-shaped passageway 23 for the filaments, and may be heated by electric resistance heaters 35. Filaments 10 entering the passageway at 31 are first heated on the lower side by contact with the heated curved surface 37, are removed tangentially therefrom, are then heated on the upper side by tangential engagement with heated curved surface 38, and leave at 32. While passing between the two surfaces, the filaments are radiantly heated from the heated surfaces of the passageway. The last heated side of the filaments may be quickly cooled by bringing it into engagement with a roll 21 (Fig. 1), held at a temperature less than that attained by the filaments. Yarn supply and withdrawal means as shown (Fig. 1), comprise a yam package 10, snubbing bar 13, yarn guide 14, feed rolls 15, snubbing pin 16, feed roll 17 and separator roll 18, withdrawal roll 21 and separator roll 22, and ring-twisting assembly 30. Roll 17 may be driven at a speed such that the yarn is stretched between rolls 15 and roll 17, in addition to the heat-stretch occurring between roll 17 and roll 21, owing to the higher speed of roll 21. Filaments having circular and non-circular cross-sections, and twisted and untwisted yarns, may be processed. Filaments so processed may be made from polyamides especially from nylon 66 and nylon 6, polyesters, polyolefins, polyurethanes, vinyl and vinylidene copolymers, and acrylonitrile homo- and copolymers.

Title: Information retrieval apparatus
IPC: G11B7/12
Filed: 1968-05-21
Abstract: 1,211,277. Automatic position control. INTERNATIONAL BUSINESS MACHINES CORP. May 21, 1968 [June 19, 1967], No.24079/68. Heading G3R. In a system in which deviations of a transducer from alignment with an information record track are detected and automatically corrected, false indications arising when a portion of the record is missing or obscure render the automatic control inoperative. In Fig.1, information stored in digital form as tracks 1-4 having alternate opaque and transparent portion 12, 13 on a film 10, is retrieved by a flying spot 15 influencing a photo-multiplier the mean output of which increases or decreases if the scan deviates toward the edge of a track as shown at 30, 31. In Fig.3, the flying spot from scanner 16 passes through the film record 10 to influence the read photo-multiplier 19. A second reference photomultiplier 20 influenced directly by light from the scanner provides a signal 21 for application to a controller 22 maintaining constant spot intensity, and also provides a signal 25 for comparison with signal 25a from the read photo-multiplier. Any variation of this comparison due to movement of the spot toward the edge of the track is detected by a differential amplifier 32 the output of which is integrated at 36 and serves to restore the scan toward the centre of the track. The control signals are reversed in sense by a controller 34 operating a switch 26 as each successive track is read. Information missing from a portion of a track gives rise to an excessive deviation from the mean signal level which is detected in magnitude and sense by detectors 41, 48, 49 and associated logic circuits, so that a one-shot pulse generator 47 applies a signal 58 to adjust the scan in the appropriate sense to cancel the false correction which will have been produced by differential amplifier 32. The output from generator 47 also causes operation of switch 26 to prevent further automatic control of scan until information is detected again or until the end of the track is detected by counting signal pulses at 44. Application to thermoplastic or magnetic records is referred to.

Abstract: 728,611. Springs. BECKETT, LAYCOCK & WATKINSON, Ltd. Sept. 25, 1953 [Sept. 26, 1952], No. 24205/52. Class 108 (3). A flat spiral spring is constituted by a strip of metal which has been strained to deform it permanently in such a manner that, when unconstrained, it coils up closely upon itself in the form of an annular body, and that when it is uncoiled and straightened by pulling the outer free end of the strip tangentially away from the coiled body, and thus rotating the body about its own axis, it offers a uniform resistance to such action. In its straightened form, the spring is curved transversely about a centre which lies on the same side of the strip as the centre about which the strip is coiled. When coiled, the cross-section of the strip is rectangular. The strip is strained by drawing it around a cylindrical bar, whilst subjecting it to pressure thereon. The spring is preferably of high tensile steel and after formation is tempered by heat-treatment.
