Title: Device for transmitting motion from a rectilinearly reciprocating member to a rotatable member
IPC: F16D41/00
Filed: 1929-07-12
Abstract: 315,872. Wellton, O. G. July 21, 1928, [Convention date]. Variable-speed gearing. - A device for converting reciprocating into intermittent rotary motion, employable in multiple to effect a continuous drive, which may be of variable ratio, so acting as a substitute for the ratchet gearing described in Specification 249,888, comprises a reciprocating worm 27 which in one direction is held against rotation by a friction or positive brake 37 and acts as a rack to drive a worm-wheel 28, and in the other direction rotates idly. A cylindrical slide 7, which is reciprocated by a cam 3 on a driving-shaft 1 engaging rollers 4, and a similar slide 24 carrying the worm 27, are connected by arms 13, 23 to slides 15, 16 mounted in a channel-shaped slide 17 which pivots about pins 18, so that the slides 7, 24 move in opposite directions. A multiple-disc brake 37, which holds the worm shaft against rotation during the driving-stroke and releases it on the return stroke, is actuated by means of screw threads 45 and an arm 49 connected to a slide 52, two conical rollers 55, Fig. 5, on which are engaged by a cam 56 on a spindle 59, which is rotated from the driving-shaft 1 by eccentrics 60, 61 and rods 62 or by chain or toothed gearing. Between the cam 56 and spindle 59 is a sleeve 66 formed with right and left handed screw threads, which may be displaced by a hand-wheel 65 to turn the cam through half a revolution and thus reverse the direction of rotation of the driven shaft 2. A hand-wheel 44 enables the brake 37 to be operated by hand. The slide 17 is vertically adjustable, if desired automatically by a centrifugal governor, in guides 21 on the machine frame, by which means the position of the pins 18 in relation to the pivots 14, 22 of the slides 7, 24 and the relative strokes of the slides may be altered, giving a variable-speed device. Bearing balls may be placed between the clutch 37 and spindle 30. Specification 266,331, [Class 80 (i), Gearing, Belt &c.], also is referred to.

Abstract: 945,842. Traversing means. GUSTINBACON MANUFACTURING CO. June 20,1960, No. 21565/60. Heading D1J. Traversing means for a strand 14 being wound into a drum 15 comprise a pair of strand engaging arms 24a, 24b rotatable about parallel axes which extend transversely of the drum axis and also to the line of travel of the strand 14, the arms 24a, 24b being arranged to rotate in spaced relationship to engage the strand in succession from opposite sides and so traverse it across the drum. In Figs. 1 and 2, in which the strand 14 is composed of a number of artificial filaments 12 (e.g. of glass) bonded at 13, each arm 24a, 24b comprises two U-shaped, diametrically offered wire members mounted on a shaft 25a, 25b. The arms are rotated by an electric motor 35 in opposite directions and 90 degrees out of phase. Subsiduary U-shaped members 26 may be mounted on the leading side of each arm member. In an alternative form, see Fig. 6, each strand engaging arm 44a or 44b comprises only one U- shaped member mounted on a shaft 45a or 45b. The shafts may be driven either in the same direction or, as shown, in opposite directions, the arms being mounted so as to be in phase when in the horizontal plane. With such a form of traversing ribbon winding is prevented by providing a secondary traverse and this is effected by mounting the strand engaging arms and their driving motor 52 on a base 48 which runs on flanged wheels 58 on rails 57a and is reciprocated by a cam 64 engaging a cam roller 63 thereon.

Abstract: 823,376. Transformers. GENERAL ELECTRIC CO. Ltd. Aug. 24, 1956 [July 28, 1955], No. 21898/55. Class 38 (2). In a " potted " transformer a magnetic core is encased in a flexible material and the windings are encased in a harder resin e.g. " Araldite " (Registered Trade Mark). In manufacture a bobbin 2 provided with windings 3a, 3b has its central aperture 9 plugged and is then placed in a mould and a resin is poured in and cured to form the hard insulation 5. The mould and plug are removed and a ferromagnetic core 4 (Fig. 3, not shown) formed of two sets of C-shaped laminations secured together by phenolic adhesive, is positioned in the bobbin. The bobbin and core are assembled in a further mould and a material is poured in and cured to form the flexible solid 6 surrounding the core.

Abstract: 1,134,068. Solvent recovery; removal of catalyst from polyolefins. REXALL DRUG & CHEMICAL CO. 17 May, 1966 [18 May, 1965], No. 21956/66. Heading B1B. Solvent, e.g. an azeotropic mixture of an alcohol and. a hydrocarbon, which has been used for extracting catalyst and low molecular weight polymers from a synthetic polyolefin, e.g. polypropylene, is purified by submitting the extract to a three-stage evaporation process carried out in three successive zones 2, 4, 6, a major proportion of the solvent being vaporized in zones 2 and 4; and the remainder of the solvent in the liquid-residue from zone 4 being vaporized in zone 6 which is supplied through line 30 with a liquid, which has an initial boiling point of above 300‹F. and is at a temperature of at least the boiling point of the solvent. The vapours from the three zones are condensed to obtain the purified solvent. An example relates to the recovery of isopropanol-herptane azeotrope using a polyethylbenzene oil as auxiliary liquid in the third stage. One of the catalysts specified is titanium trichloride activated with diethyl aluminium monochloride. Zones 2 and 6 may each be provided with a series of trays. The vapour from zone 4 is passed into the upper section of zone 2, and the vapour from zone 2 is conducted to condenser 39. Part of the condensate is refluxed through line 44 to the upper part of zone 2. The vapour from zone 6 is condensed, and the condensate is in part retluxed through line 36 to zone 6. The remainder of the condensate from zone 6 is united in line 45 with the non-refluxed part of the condensate from zone 2, and the united stream is passed through unit 47 which contains an adsorbent bed, such as molecular sieves, which removes traces of water from the solvent. The purified solvent is withdrawn from the system through line 48.
