Title: Improvements in reversible driving means
IPC: B23Q5/04
Filed: 1943-03-13
Abstract: 568,149. Transraitting mechanical power. ENGLISH ELECTRIC CO.. Ltd., and CARNEGIE. H. S. March 13, 1943. No. 4136. [Class 38 (iv)] A non-reversing driving means, such as an engine or an electric motor 1, may drive a, reversible output shaft 12 (not a ship propulsion shaft or ship's steering gear) through either of two gear trains. A hollow shaft 6 carries a. wheel of one train, another, hollow shaft 8 carries a wheel of the other train, a gear-box encloses both trains, a shaft 3 passes through both hollow shafts and the gear-box and electromagnetic slip couplings 4, 5 outside the gear-box are adapted to couple either of the hollow shafts to the through shaft according to the position of switching means 19 controlling the excitation of the couplings. The couplings are of the type in which torque is transmitted by the interaction of a primary field system with a secondary system when current is induced in the latter by relative movement between the systems. The primary system may have salient poles, as shown, and the secondary system may be of squirrel-cage or slip-ring induction motor type ; or it may be of eddy current type, or according to Specification 561,414. The switching means may be a master controller, e.g. as in Specification 568,148, [Group XXXIII], having a follow-up part driven by the output shaft so as to deenergize a coupling when that shaft reaches a position corresponding to that of the controller. It may be of the potentiometer type, as in Specification 568,148, [Group XXXIII], giving progressive variation of coupling excitation. The ratios of the gear trains may be different. The speed of the non-reversing driving means may be changed with a change in the coupling energized. Various arrangements for braking are described. The invention is applicable, inter alia, to roller tables and screw-down gear in rolling mills and to reciprocating planing machines. Specifications 541.825, 564,635 and 564,639 also are referred to.

Title: Improvements in automatic weighing and printing scales
IPC: G01G23/18
Filed: 1939-02-09
Abstract: 524,851. Weighing-apparatus. TOLEDO SCALE MANUFACTURING CO. Feb. 9, 1939, No. 4252. Convention date, June 1, 1938. [Class 143] An automatic weighing and printing scale comprises a light type disc bearing higher order type characters on its face, a pivotally mounted arcuate strip of thin light material located in the plane of the disc and bearing type characters for a lower order of weight, and means (pawl mechanism) adapted to engage locating devices (notched surfaces) for moving the type disc after attainment of equilibrium, for the purpose of correctly positioning the type disc in the required printing position relatively to the arcuate type strip. In obtaining a printed record, a record paper is inserted between a platen 16, and a type disc 1 and units printing strip 13. When the load is applied to the scale the type disc is automatically rotated to a position corresponding to the weight. The operator closes a transitory switch and causes the core 26 of a solenoid 27 to rise and lift the sliding bar 30. During the first part of the movement, a spring- pressed jaw 38 on the bar, gripping a friction block 40, rocks a bell-crank lever 43. The initial movement of the bell-crank lever 43 permits a light wire detent to descend upon the edge of the printing disc 1. If the wire detent enters one of a number of equi-distant notches 55 in the disc it moves the disc slightly to prevent a pawl 45 (actuated as described below) from engaging and damaging the corner of an adjacent notch. Further movement of the bell-crank lever 43 allows a brake to press on the edge of the printing disc. The pawl 45 is pivoted on the bell-crank lever 43 and now engages the edge of the printing disc and slides therealong until it rides into one of the notches 55. In entering the notch, the pawl also enters one of a series of notches in a ratchet sector 64, the sector consequently being displaced together with the type disc by the further advance of the pawl until the pawl is stopped by a jam bracket 66 and temporarily locked by a latch 67. The movement of the ratchet sector 64 is transmitted to a lever 12 carrying the arcuate printing strip 13. On further upward movement of the bar 30, slipping occurs at the friction block 40, and a finger 77 on the bar 30 allows a wire detent to enter a notched quadrant 78 projecting from the lever 12 in order to set the arcuate strip 13 accurately. In this manner the correct units digit on the strip 13 is aligned with the tens and hundreds on the disc 1. During the final upward movement of the bar 30 the latch 67 is liberated and the solenoid operating in the manner described in Specification 345,683, makes an impression of the weight on the paper and breaks the circuit. The core of the solenoid is pulled down by a spring and the parts are restored to their first positions.

Abstract: 397,471. Filters. SERCK RADIATORS, Ltd. and WAGNER, C. 0., Warwick Road, Greet, Birmingham. Feb. 13, 1932, No. 4287. [Class 46.] A filtering-apparatus of the kind comprising a metal or other strip or a wire coiled into a spiral form, and inner and outer parts to which the ends of the coil are secured, relatively movable to vary the tension of the coil and d consequently the width of the spaces between the convolutions, is characterized by the provision of a rotary or oscillatory brush or scraper which assists the reverse flow in cleaning the filter. As shown in the Figure, the coil a is secured at its ends to rings e, d, the ring e being adjustably rotated by the square-ended spindle f whilst the ring d is feathered, to prevent rotation, in the casing g. The coil assembly which is retained in position by a spring wire clip i, rests on a ring j having a central boss and cross bar l which supports the spiral, whilst the central boss and the ring j seal the filter at the regions of the junctions of the spiral with the rings e, d. The filter is cleaned by reverse flow, and brushes o on a manually rotatable shaft m assist in the removal of the solid material which is collected in a trap r. In a modification, the inner ring e is held stationary whilst the outer ring d is rotatable for adjustment by a manually-operated pinion engaging gear teeth on the outer edge of the ring d. The brush o is operated from above, the shaft passing through the stationary centre ring e. In a further modification, the outer ring d is held stationary as shown in the Figure, but the inner ring e is secured to an upstanding sleeve carrying a gear wheel which is meshed with a gear wheel on a hand-wheel shaft whereby the inner ring e is adjusted. The hand-wheel shaft carrying the cleaning brush passes through the sleeve, the brush as before being beneath the spiral The brush carries, in addition to the bristles, a rigid metal strip which serves both as a scraper and a support for the underside of the filter coil. If desired a plurality of filtering elements may be superposed either in contact or with intermediate spaces with a brush or scraper in each space.
