Title: Improvements in means for cutting off lengths of material accurately
Inventor: MARSHALL WALTER
IPC: B23D45/18
Filed: 1961-01-19
Abstract: 1,002,951. Sawing; cutting tubes etc.; cutting extruded material. SPEEDEX (ENGINEERING) Ltd. April 4, 1962 [Jan. 19, 1961], No. 2286/61. Headings B4B, B5A and B5L. A machine for cutting predetermined lengths from continuously extruded or other preformed material has a carriage 1 with clamping means 19 for engaging the moving material, a material supporting table 29 attached to and moving with the carriage and length determining means 35 carried by the table for controlling the clamping of the material and the movement of the cutter to cut it. The cutter may be of the disc or band saw type, a knife or guillotine or a heated wire. The table 29 runs on guides 2 and its movement with the work is assisted by a chain 10 and weights 11. It is hinged to the carriage and supported by a roller 31 on an adjustable stand 32; extension tables 29a may be provided. A latch 12 holds the carriage 1 in its starting position and is releasable by a piston and cylinder unit 13. The saw 7 is driven continuously or intermittently and is swung up through a slot in the carriage by a piston and cylinder unit 9. Clamps 19 are adjustable on a bridge piece 15 which can be vertically positioned on pillars 14 by locking levers 17 engaging notches 16 and a piston and cylinder unit 18 pulls the pillars down to clamp the carriage to the work. In alternative clamping means for channel-section material, a bracket on the bridge piece resiliently carries a block fitting within the channel section and resilient pads on the bracket engage the top of the legs of the channel section. Adjustable guide plates or blocks 20 are provided. The lengthdetermining means may be a micro-switch, an acoustic sensing switch or proximity gauge means or, as shown, photo-electric means 35 mounted on brackets on the supporting table. When the work interrupts the light beam, a pneumatic system operates to close the clamps 19, release the latch 12, start the saw, if necessary, and swing it upwards. When the cut has been made, the saw moves down, the clamps are released and piston and cylinder unit 41 returns the carriage to starting position. The cut section is pushed on by the moving work and operates a trip 33 connected to a valve or switch 34 and piston and cylinder units are operated to cause ejectors 39 to push the cut section off the table.

Title: Boron-removing resin and process for removing boron compounds from fluids
IPC: C08F8/32
Filed: 1956-01-24
Abstract: Ion exchange resins comprise a synthetic insoluble cross-linked polymer matrix which has attached thereto functional groups comprising groups of the form -R1N(R)-Z in which R1 is a divalent saturated hydrocarbon group having not more than four carbon atoms, R is a monovalent organic group, and Z is a sorbityl, mannityl, galactityl, talityl, arabityl or ribityl radical.  R may be methyl, ethyl, n-propyl, isopropyl, n-butyl, sec.-butyl, tert.-butyl, hexyl, lauryl, octadecyl, cyclohexyl, phenyl, benzyl or napthyl.  The matrices may be prepared by copolymerizing monovinyl aromatic hydrocarbons, e.g. styrene, vinyltoluene, vinylnaphthalene, ortho-, meta- or para-ethylstyrenes, and vinylanthracene, with compounds containing at least two non-conjugated CH2=C< groups, e.g. divinylbenzene, divinyltoluenes, divinylnaphthalenes, divinylethylbenzenes, divinylxylenes, trivinylbenzenes, diallyl esters such as diallyl phthalate, ethylene glycol diacrylate and ethylene glycol dimethacrylate.  Polymerization may be effected in bulk, solution, emulsion or preferably suspension, e.g. in the presence of magnesium silicate, in the presence of catalysts, e.g. dimethyl azobis isobutyrate, a ,a 1-azobis-isobutyronitrile, benzoyl peroxide, acetyl peroxide, lauroyl peroxide, stearoyl peroxide, tert.-butyl hydroperoxide, ditert.-butyl peroxide, ammonium perborate and ammonium persulphate.  The polymers may be haloalkylated, e.g. by reacting with an aldehyde and hydrochloric acid, or with a dihalide or chloromethyl methyl ether in the presence of a Friedel-Crafts catalyst such as aluminium chloride, and the products thereafter reacted with amines of the form R-NH-Z, e.g. N-methyl-glucamine, preferably after swelling with a solvent for the amine, e.g. dimethylformamide, benzene, toluene or ethylene dichloride.  The resins are particularly suitable for removing boron compounds, e.g. borates, from solution.  Specification 654,706 is referred to.

Title: Method of and apparatus for straightening the weft of fabrics
Inventor: DALGLISH JOHN
IPC: D06H3/12
Filed: 1953-01-30
Abstract: 738,602. Automatic control of moving webs. DALGLISH & SONS, Ltd., J. Jan. 25, 1954 [Jan. 30, 1953], No. 2683/53. Class 38 (4). [Also in Group VIII] In Figs. 1 and 2 a web of fabric 15 is fed over roll 38 and electronic guiders 40 to guide rails 16A, 17A along which its selvedges are conveyed by continuous chains of pin or clip elements driven through sprockets 20, 21 from a motor 24. Differential gearing 25 is associated with the drive to sprockets 20, 21 so that their relative speeds may be adjusted automatically to correct skew. Wheels 26 on a shaft 37 engage the fabric at the entry end of the guide rails and overfeed it to produce ripples R across the web corresponding to the direction of the weft. Light from a lamp 27 focused in the direction of travel of the web is reflected from the trailing edges of the ripples and influences a photo-cell 29 adjacent each guide rail. Unequal influence of the two photo-cells due to skew of the weft produces an electrioal output which is amplified and applied to energize an appropriate solenoid-operated brake associated with the differential gearing 25 to correct skew by altering the speed of feed of one selvedge relative to the other. The fabric is wound up on a batcher roll 61. The spacing of the guiderails is adjustable by screws 31-33 and the rails are hinged at 30 so that portions of them may be arranged closer together at the entry end to permit the web to be fed in without tension in the weft direction. Arrangements in which only one photo-cell is employed and arrangements in which the photo-cells and/or lamp are beneath the fabric are referred to. In a modification skew is corrected by adjusting the relative speed of overfeed wheels 26. In this arrangement undue tension in the fabric between roll 38 and guider 40 is prevented by arranging frame 39 carrying roll 38 to swivel about a vertical axis. In Fig. 8 ripples R are produced in fabric 15 by the closing up of pin carriers 42 hinged at their inner edges 43 while in Fig. 9 the ripples are produced by the closing up of pin-and-slot couplings 45, 47 between pin carriers 46. With the arrangement of Fig. 9 the main drive through which skew is corrected is to the sprockets 48 at the entry end. In Fig. 10 the ripples are produced by overspeed wheels 26 feeding on to pin carrier wheels 51 associated with each selvedge and constituting the main drive through which skew is corrected. Wheels 51 are inclined to each other to graduallytake up the necessary initial slack in the direction of the weft.

Abstract: 184,768. Dandois et Cie, J. B. Aug. 13, 1921, [Convention date]. Holders for sliding windows.-A sliding window is held in any position by being pressed between ledges on the uprights of the door and a pair of pivoted vertical bars moved towards the window for clamping it in position, or away from it for releasing, by means of cam-actuated horizontal rods which operate shoes on horizontal arms mounted on the door uprights and inclined towards the face of the door. The rods a are suspended from bolts d on the top of the door and are rigidly connected by a cross-piece k carrying a bracket j, to which is pivoted a disc k at m. The disc k has two camslots n in which travel the heads o of studs or nuts p adjustably mounted on horizontal screw-threaded rods q terminating in shoes t which slide on the brackets w mounted on the door. When the handle l of the disc k is turned, the heads o of the studs travelling in the cam-slots n and guided by the horizontal slots s in the fixed bracket cause the rods q to move towards or away from each other so that the shoes t slide along the inclined arms v of the brackets w towards or away from the plane of the door, forcing the cross-piece towards or away from the glass and thereby causing the glass to be gripped between the bars a and door ledges h, or released. A turned-over portion of the bracket j has a slot z with recesses x, x<2> for holding the handle l in either of its extreme positions. The bars a are separated from the heads of the bolts d and the door face e by rubber washers f, g.
