Title: Improvements in or relating to reversing mechanism for reciprocating tables or the like
IPC: B24B47/04
Filed: 1920-07-09
Abstract: 148,386. Norton, Co., (Assignees of Fraser, W. F.). Dec. 14, 1917, [Convention date]. Reversing-gearing adapted to drive a reciprocable body such as the work table of a grinding- machine is modified to cushion shocks on reversal. The actual cushioning is effected by the axial sliding of a worm 6 which drives the table 2, Fig. 4, through a rack 3, pinion 4, worm-wheel 5 and other gearing. The shaft 7 of the worm 6 is driven alternately in opposite directions from a driving-shaft 14, Fig. 5, as a double clutch 9 is moved to left or right. The worm 6 slides upon the shaft 7 and bears against a sleeve 23, which is connected by an arm 29 to a slide 30 moving in guides 31. The slide 30 carries an arm 40 having a pin 39 engaging a cam-slot 38 in a lever 34, which turns about a fixed pivot 35, and has an arm 37 engaged by one of a pair of tappets 44 on the table 2. During the uniform medial movement of the table 2, the pin 39 resides in a straight middle portion of the slot 38. When a tappet 44 strikes the lever 34, the pin 39 passes on into a curved portion of the slot, allowing the slide 30 to move on and the worm 6 to yield, bringing the table 2 gradually to rest. A stop 71 upon the slide 30 finally trips a pawl 65, which allows a lever 52 to throw over the clutch 9, starting the reverse motion. In a modification, the pivoted cam lever is replaced by a slide.

Title: Apparatus for carrying out rectilinear adjusting movements
IPC: H02K7/06
Filed: 1954-07-12
Abstract: 792,801. Screw jacks. RAHMANN & CO. GES. July 12, 1954 [July 13, 1953], No. 20340/54. Class 78 (3). [Also in Group XXXV] In a screw-and-nut jack of the type comprising a screw-threaded spindle 7 which is axially slidable but non-rotatable in a housing 1 containing an electric motor the rotor 6 of which drives the nut 6<SP>1</SP>, the rotor, which is axially slidable to effect operation of contacts to switch off the drive, is mounted on a tubular shaft 18 supported within the housing in end bearings 17 carried by end covers fitted to the housing, the tubular shaft being rotatable and also axially movable in relation to the spindle which extends through the bore of the tubular shaft. Rotation of the spindle 7 is prevented by keys 12 engaging a groove in the spindle. For cutting off the current to the motor at end positions or if the spindle should jam a bush 9 is slidable on shaft 18 near each end, being held against rotation by pins 11 sunk in the end covers and passing through holes in lugs 9<SP>1</SP> secured to the sleeve. An insulated cross bar 16 is secured on these pins and carries one or more contacts 15 normally engaging contacts 14 resiliently supported on an insulated ring 13 slidable on the pins 11. Springs 10 act on the rings 13 and sleeves 9 at both ends of the housing to press the sleeves against thrust bearings 8 which in turn act on the rotor through sleeves 19 to hold the rotor in a central position. When resistance to the sliding movement of spindle 7 occurs the rotor winds itself towards one or other end of the housing according to its direction of rotation and opens the contacts 14, 15 to break the motor circuit. Further contacts may be arranged to operate an indicating device. Shaft 18 may be extended beyond one or both ends of the housing and the projecting end fitted with a handle. The screwed portion of spindle 7 may be continued outside the housing to any desired length.

Abstract: 1304071 Lifting apparatus H NIELSON & SON MASKINFABRIK A/S 28 April 1970 [23 May 1969] 20441/70 Heading B8B [Also in Division H1] A magnetic lifting device comprises a lattice girder 1 comprising upper and lower flanges 2, 3 interconnected by intervening members 4 suspended at 5 from a hoist (not shown) and carrying plural elongated electromagnets 6 retaining, e.g. a T-beam 7 (Figs. 1, 2). End pins 8 of the magnets are resiliently suspended by slings 9 from spring suspension members 10, mounted on a longitudinal shaft 11 carried in fixed bearings 12 of the lattice girder, and rotatable to turn the magnets, which are interconnected in pairs over damping springs 12a. A spring suspension member (Fig. 3) comprises a divided grooved rope pulley 13, 14 rotatable relative to shaft 11 and carried on bronze sleeve 15 axially slidable thereon against covered coaxial pressure coil spring 16 and spring ring 17; the pulleys being separated by a low friction nylon disc having an embedded molybdenum disulphide element and having opposed female screwthreads of equal diameters and slops # 1 =# 2 =45 degrees (Fig. 4, not shown). The sling ends are passed over the respective grooves and are made fast to the separate pulleys at 9<SP>1</SP>, 9<SP>11</SP>, while the bight makes 1¢ turns round pin 8. The sleeve 15 has first and second spaced male threaded sections (Fig. 4, not shown) engaging the female threads of the pulley sections, and with the ring 17 and spring 16 are mounted on hub 23 keyed to shaft 11 with a welded strip flange 24 abutting a nylon and molybdenum disulphide low friction slide disc 25, and a further stop ring 27 at the other end engaging nut 26 threaded to the hub. The sleeve 15 is inwardly provided with an axial locating groove (Fig. 5, not shown) engaging a tongue of hub 23. The shaft bearings are secured on flange 3 to the girder and shaft 11 is geared for drive from motor 30 over friction overload coupling 32 and limit stop member 33. In operation, when shaft 11 is motor turned, pulleys 13, 14 rotate to unwind and wind opposed ends of the slings to turn the several magnets through a required angle. Lifting, e.g. an iron beam causes extension of the slings, and extension of the sling passing over pulley 13 will rotate the latter relatively to shaft 11 and the female thread engaging a threaded section 21 of sleeve 15 allows the pulley to rotate and shifts sleeve 15 axially of the shaft, compressing spring 16. Similarly the engagement of threaded section 22 of the sleeve with the female thread of pulley 14 rotates the latter counter to the rotation of pulley 13 to unwind the other end of the sling, so that the two sections of the latter are equally extended.

Abstract: 794,314. Shearing. SMITH & CO (POSSIL), Ltd., H., and JEFFREY, D. C. July 5, 1956, No. 20843/56. Class 83 (4). [Also in Group XXIX] In an hydraulic guillotine plate shearing machine in which the movable blade holder is actuated at each end by two secondary rams supplied with equal amounts of pressure fluid by a main ram, the rate of supply of fluid to the secondary rams is decreased when the pressure increases as the blade cuts the sheet. The primary ram 14 is stepped and expels liquid in equal amounts from chambers 13a, 14a to the secondary rams. The output of the fixed displacement supply pump is directed into a chamber 17 to provide a fast speed under low load but when the blade engages the sheet the increase of pressure in chamber 17 opens a valve to admit the liquid from the pump to chamber 18 in addition to chamber 17 so that the speed is decreased.
Patent GB-1088386-A (GB)
Title: High bulk yarn and process for its preparation
IPC: D01F8/10
Filed: 1965-05-18
Abstract: A non-elastic filamentary composite structure, comprised of at least two continuous polymeric components adhered in a continuous side-by-side relationship to one another, has the property of permanently retaining 25%-75% of the composite side-by-side structure on being treated under tensionless conditions in a hot medium.  The structure may be in the form of continuous filament, staple fibre or fabric.  The composite filaments are made by extruding and coagulating a laminar liquid structure having at least three alternating layers of two different synthetic polymers, one being elastomeric, the other being hard, essentially inelastic, wherein every layer of polymer has at least one continuous common interface with a different polymer layer, and then washing the filaments, drawing the washed filaments at least two times and drying.  Drying may be effected in two stages at e.g. 75-105 DEG C.  The dried non-elastic composite filaments are then treated in an untensioned state with a hot p  medium, e.g. boiling water to partially separate the components and produce a filamentary structure in which the elastomeric and hard polymer components are permanently fused in side-by-side relationship in at least two recurring segments of the overall structure, said fused segments being separated by recurring segments in which the components are separated, there being at least one separated segment and at least two fused segments per staple fibre length and the cumulative length of the recurring fused segments comprising 25-75% of the overall length of the filament. The heat-treatment, by which the elasticity of the structure is developed, may be carried out on the filament, or on the fabric made therefrom.  Separation of the components may be aided by flexing the structure.  The elastomeric component may be a spandex polymer, and the hard, inelastic component may be a polyamide, polyester, polyolefin, polyether or polyacrylonitrile.  The laminar liquid structure may be obtained by use of the plate mixing device disclosed in Specification 980403.  Examples describe the wet-spinning of spandex-acrylic systems, and the development of elastic properties and crimp by exposure of the composite filaments to boiling water. In example 1, undeveloped composite filaments are mechanically crimped, cut into staple fibre, blended with conventional acrylonitrile/vinyl acetate staple, processed into worsted yarn, and knitted into a non-elastic twill fabric.  The latent stretch of the fabric is then developed by treatment with boiling water.
