Abstract: 255,189. Linotype & Machinery, Ltd., and Stern, C. L. May 19, 1925. Dust, fluff, and the like, collecting.-A machine for removing fluff and dust from printing paper and the like comprises a pair of feed rollers 6a, 8 to which the paper is supplied, pairs of rotary brushes 21, 22 between which the paper is passed, a suction chamber 2 which is connected to a suction pump through pipes 63 and contains the brushes, and delivery rollers 16a, 18 for delivering the paper from the chamber. As shown, the paper is in the form of sheets fed from a pile 4 and finally deposited on a delivery table by means of a delivery carriage 19 reciprocated from a crank 62 through lever-and-link mechanism. Pairs of feed rollers 13, 13<a>, tapes 14, 20. and guides 60 feed and guide the sheets through the chamber 2. The rollers 8 are mounted on swing- ing arms 35 oscillated by cam-actuated links 38, 39 to allow a sheet to be moved up to cam-controlled stops 47. A table 61 supports the sheets up to the first pair of rollers 13, 13a. The brushes are carried by swinging arms 23, 23a, the arms 23 for each upper brush 21 being fixed on a rod 24 oscillated through links 26, 27 by one of a set of cams 31 fixed on a shaft 32 and arranged so that the brushes 21 are lowered in succession on to the sheets. The lower brushes 22 are moved in unison with the brushes 21, their arms 23<a> being actuated from the arms 23 by gear sectors 25. The first three pairs of brushes are rotated so as to oppose the movement of the sheets, the dusting of the leading edges being performed by the last pair which rotate in the reverse direction. Each brush is made up of coaxial sections, the sections of the various brushes being arranged in staggered relationship so that the whole surface of a sheet is dusted. An additional pair of brushes may be provided arranged to the left of the last pair and with its sections staggered with respect thereto so as to complete the dusting of the leading edges of the sheets. To exclude dust from the chamber 2, flaps are provided where the sheets enter and leave.

A taper turning attachment for a turret lathe comprises a bracket 1 attached by a flange 2 to the lathe turret 3, a small bracket 23 secured to bracket 1 which pivotally supports a toolcarrying arm 30 at 32, a slidable tool holder 38, a stay 49 pivotable at 47 on arm 30 and slidable on bracket 1, which is clamped in the required angular position of arm 30, by bolts 51, and drive means connected to work 59, or the machine spindle for feeding tool holder 38 to machine face 58 by tool 40. A shaft 64 is driven from work 59 by an expansible bush 65 and drives a shaft 61 through a clutch 63, the shaft being slidable in a worm-shaft 6 carried by bracket 1. Worm 8 meshes with a worm-wheel 9 on a shaft 11, and pinions 15, 16 on the latter drive two gears 12, 13 loose on a further shaft 14, a clutch 17 between gears 12, 13 being provided for selecting the required gear ratio. A sprocket 19 on shaft 14 drives a sprocket 21 on a shaft 22, in bracket 23, by a chain 20, arm 30 being pivotable about shaft 22. A pinion 31 secured to sprocket 21, drives an idler pinion 33 which meshes with a pinion 34 slidable on a shaft 35, and a pinion 42 on this shaft meshes with a rack 44 on tool holder 38. A hand wheel 45 slidable on shaft 35 enables the shaft to be rotated for setting tool holder 38, when pinions 33, 34 are disengaged, and pinion 34 is thrown out of mesh when tool holder 38 reaches the end of its feed movements. This occurs when a peg 68 on rack 44 trips a lever 70 pivotally mounted on shaft 35, thus disengaging the lever from a notch 73 in a spring-urged slidable spindle 74 and allowing the spindle with a plate 82 attached thereto to slide to disengage pinion 34 from pinion 33. Tripping can also be effected by pressing a lever 83 on a spindle 84. The angle of arm 30 can be set by a sine bar 53.

Abstract: 589,046. After-treating isoolefin or isoolefin - diolefin polymers. ARNOLD, J. C. (Standard Oil Development Co.). July 12, 1944, No. 13339. [Class 2 (iii)] In a process of preparing high molecular weight polymers by polymerizing in a reaction zone an isoolefin, e.g. isobutylene or a mixture of a major proportion of an isoolefin and a minor proportion of a conjugated polyolefin, e.g. isoprene, piperylene dimethyl-butadienes and myrcene in a diluent at a temperature below - 40‹ C. in contact with a Friedel-Crafts type catalyst to form a slurry of solid polymer particles in cold reaction liquid, separating the solid polymer particles from the cold reaction liquid at substantially the reaction temperature and returning the latter to the reaction zone, an improvement comprises transferring the separated polymer particles to a flushing zone concurrently with a stream of sealing gas sufficient to prevent backing up of flashing gases into cold equipment. Hot liquid in the flashing zone is preferably water at 130‹ to 160‹ F., and the sealing gas may be natural gas, hydrogen, methane or nitrogen. Referring to Fig. 1, cold slurry from the reaction vessel overflows through line 11 via weir box 14 on to vibrating screen 13 in chamber 12. The cold liquid passes through the screen to trough 15 and hence out of chamber 12. The polymer particles fall from the end of the screen into a vibrating hopper 22 and via pipe 23 into the heated liquid in flash chamber 21. Sealing gas is supplied via chamber 12 from either or both of pipes 29 and 30. The flashed-off gases leave chamber 21 via pipe 32 and the polymer via line 33, rollers 35, 36 and 37, picker roll 39, conveyer feed 40, belt 41 and tunnel drier 42. In Fig. 2, the polymer enters casing 102 and drops on to screen 101 and so to vibrating feeder 105 and flash chamber 108 which has a turbine-type mixer 109, a water inlet pipe 110 and steam header 111. The polymer slurry passes under weir 113 and overflow weir 112 and the sealing gas is introduced via line 115. Fig. 3 shows an embodiment with a screen conveyer 202 between the screening enclosure and the flashing chamber. In Fig. 7, slurry enters at 504 and passes via shoot 505 to vibrating screen 501 supported by spring suspension 516 and vibrated by electromagnetic vibrator 508. Examples of the treatment of an isobutyleneisoprene copolymer with methyl chloride as diluent and of an isobutylene-butadiene copolymer are given. Specifications 432,196 and 565,974 are referred to.

Title: Improvements in or relating to machines for forming flanges on sheet metal
IPC: B21D19/08
Filed: 1932-05-09
Abstract: 383,555. Flanging sheet metal. ENGINEERING & RESEARCH CORPORATION, 2014, 5th Street, Washington, U.S.A. May 9, 1932, No. 13365. Convention date, April 4. [Class 83 (iv).] A metal sheet 65 is flanged step by step around its periphery by pressing its edge by a die 49 secured to an oscillated arcuate holder 45, the sheet edge being held abutted against a stop 64 and the sheet being momentarily clamped by the holder 63 against which the sheet is flanged. The die 49, Fig. 6, is shaped to provide clearance for the gauging stop 64. The die holder 45 is oscillated in arcuate guides 46 by a crank pin 34 rocking an arc-shaped lever 39 about its pivot 37 the link 42 and the die holder 35 is also oscillated. Stroke adjustment is provided by sliding the coupling block 40 in the arc of the lever 39 through linkwork 21 &c. from the foot treadle 6 which can be fixed in desired position by lever 83. During pressing the sheet is clamped to the bed by the holder 63 reciprocated from the cam 32 operating a push rod 71 to rock the lever block 53 carrying the foot 63. A handlever disconnects the drive for the sheet clamping part 63. As the parts 63, 64 are in one piece or built up from two pieces the depth or angle of flange can only be altered by changing for another piece with the desired spacing &c. Fig. 10 shows a flange with a depression in it. Fig. 14 shows the flanging of a Z-bar. In flanging an irregular curved sheet, Fig. 17, the sheet 115 is clamped to blocks slidable in crossed slots 110, 111 and hand-fed to the flanging die the depth of flange being determined by its position relative to the die. The step by step feed may be automatic, Fig. 20, by a toothed or rubber-covered foot 133 which pushes the sheet round as it is oscillated from the die holder 45 which pulls a link 122 to rock a shaft 129 coupled to the foot 133. For flanging along a straight line the work is constrained to move along the table in a straight line. Specification 383,554 is referred to.

Title: Improvements in and relating to Grinding Gauge-pieces and the like.
IPC: B24B37/08
Filed: 1919-05-27
Abstract: 128,907. Pratt & Whitney Co., (Assignees of Hoke, W. E.). June 28, 1918, [Convention date]. Block, rubber, and like apparatus.-Gaugeblanks are lapped between two ring-shaped laps 1, 2, the upper of which is capable of a free floating movement towards or away from the lower but is held against lateral oscillation. The blanks are mounted loosely in holes around the periphery of a thin disk 5, the spindle 6 of which is mounted loosely in the crank-arm of a driving-shaft. As this shaft rotates, the disk 5 is traversed across the face of the lap by the throw of the crank-arm, and the weight of the upper lap 1 acting upon the gauge blanks causes the disk to rotate about its spindle 6 once every five or six revolutions of the driving- shaft ; also each blank rotates about its own individual axis. The result of this compound circular and precessional movement is stated to be that all the gauge-blanks pass successively between all parts of the two lapping-surfaces, travelling in a continuous cycloid or spiral curve. Alternatively, the spindle 6 may be positively rotated in addition to having an eccentric throw imparted to it from the driving-shaft. Limit stops 4 may take the weight of the upper lap when the blanks have been ground to the required height; or an adjustable screw may be used to limit the approach of the two laps. The blocks are transferred symmetrically from their holes in the disk 5 at an intermediate stage of the lapping operation so as to ensure equal treatment. In operation, the whole lapping-device is immersed in a liquid bath kept at a constant temperature. In order to obtain gauges of a definite size with a high degree of accuracy, the following method of measurement is adopted; it is stated that all the pieces produced in one lapping operation are absolutely equal in height. Thirty-six pieces, say, are lapped in the first operation, and the whole of them are taken out from the disk from time to time and piled up to compare with a standard yard measure. When the pile exactly equals the yard measure, each is an exact inch, and ten of these mav be taken as a basis against which to measure one hundred other pieces formed all together in a second operation, to obtain a gauge exactly one-tenth of an inch in height, and so on.
