Title: Improvements in and relating to machines for mixing or masticating rubber and like materials
IPC: B29B7/12
Filed: 1921-01-10
Abstract: 157,829. Farrel Foundry & Machine Co., (Assignees of Bowen, D. R.). Sept. 14, 1917, [Convention date]. Mixing by compression; stationary batchmixers with rotary stirrers.-A machine for mixing and masticating rubber consists of a cylinder containing a bladed rotor which works the material to and fro from end to end of the cylinder. The mixing-chamber 20 consists of a cylindrical body bolted to heads which are extended to form pedestals 21, and stuffing-boxes 22. Packing-rings 27 are placed in the stuffing- boxes and are compressed by glands 2,6 which are tightened by bolts 28 and thus prevent the rubber from being extruded through the bearings. The glands form the bearings for the shaft 25x of tEe rotor 25, as described in Specification 172,976, and the shaft and rotor are hollow to permit the mixture to be cooled or heated by circulation of water or steam. The chamber 20 is formed with a central transverse rib 45, and the rotor has blades 25<b> which are inclined so as to force, the rubber to and fro through the narrow space between the edge of the rib 45 and the rotor. The blades 25b have facetted working-faces 25<c> which smear the rubber against the wall of the chamber and the surface of the rib. The material is fed into the chamber 20 through an upright cylindrical shoot 29, containing a plunger 31 which is operated by an hydraulic pressure cylinder 32. The plunger forces the material down into the chamber and holds it in contact with the rotor blades. The lower half of the chamber 20 is not bolted to the heads but is hinged to the upper half, and can thus be swung downwards to discharge the material from the chamber. The rotor may be in the form of frustums of two cones, as shown, and may be provided with two or more blades. In a modified form the rotor may be cylindrical, the blade conforming to the walls of the chamber and to the rib, the base of which may extend the whole length of the chamber. The inner ends of the blades may also pass slightly beyond the edge of the rib. Specification 172,977 also is referred to.

Title: Apparatus for curling sheet metal
IPC: B21C47/00
Filed: 1964-01-14
Abstract: 1,045,542. Curving, coiling and shearing. E. R. BODNAR. Jan. 14, 1964, No. 1591/64. Headings B3E and B3W. Apparatus for maintaining tension in a highspeed slitting line and including curving means having operative and inoperative positions for curving starting ends of the sheet material being split, comprises a pair of horizontally-disposed pressure rollers resiliently biased together between which the sheet is passed, a D.C. motor drive having speed control means and operatiyely connected to one of the rolls to feed the sheet therebetween and maintain tension in the line, a driven curving roll rotatably supported in spaced-apart parallel relationship with said pressure roll adjacent the output side thereof, movable sheet-supporting means between the pressure and curving rolls including a first diverting roll, and a second vertically adjustable roll diverting rotatably supported in the operative position to force the sheet against the curving roll and in an inoperative position away from the curving roll to clear the sheet coming from the pressure rolls. The apparatus 11 comprises D.C. motor-driven and idler pressure rolls 15, 16, a sectional or onepiece A.C. motor-driven curving roll 22, first and second diverting rolls 29, 33, an inclined guide table 32 whose upper surface is tangential to the rolls 22 and 16 and a catch bin 38 having a curved back wall 39 and an hydraulicallyoperated tilt arm 40. The rolls 16, 29 and 33 are moved into and out of their operative positions by hydraulic cylinder units 17, 18; 34, 35; and 36, 37 respectively. In use, the leading end of a strip is severed therefrom by a known type of motor driven knife unit travelling along a rail 52 located in advance of the rolls 15, 16 which frictionally feed, due to the pressure exerted thereon by the hydraulically-biased roll 16, the discard end over the table 32 under roll 29 and against the roll 33 which forces the end against the curving roll 22 causing the discard to assume a tight coil 46 about itself which drops on to the arm 40 from whence it is discharged into a bin. A pivoted scraping knife or bar 54 is preferably fitted and resiliently biased against the roll 15. A pair of adjustable stop assemblies 60 engaging the roll 33 supports serve to limit the setting of the roll 33 relative to the roll 22 and hence the resultant radius of curvature of the coil 46. The surfaces of the roll 22 may be knurled to provide a more positive gripping action on the discard ends in order to ensure tension between it and the rolls 15, 16. The rolls 29, 33 are retracted clear of the strip during normal throughfeeding. The apparatus may be located in a high-speed metal slitting line, Fig. 4, which comprises an uncoiling unit 61 feeding strip or sheet over a guide roller 62 into a slitting unit 63 and thence via the tension and curving unit 64 to a recoiling unit 68. During recoiling, the rolls 15, 16 maintain the material coming from the unit 63 in tension, the roll speed being electrically controlled in a known manner.

Title: Improvements in and relating to oxidation processes
Filed: 1937-02-25
Abstract: In the production of olefine oxides by the reaction of olefines with oxygen or a gas containing oxygen, over-oxidation is restrained by including in the mixture a small proportion of one or more of the following substances, namely, an aromatic hydrocarbon such as benzene or xylene, an aliphatic alcohol such as ethyl alcohol, a halogenated aliphatic hydrocarbon such as ethylene dibromide or ethylene dichloride, a halogen such as iodine, an aromatic amine such as aniline, or an organo-metallic compound such as lead tetraethyl.  The proportion of the substances specified does not exceed about 0,5 per cent of the volume of the reaction mixture.  The reaction is effected under conditions known to be favourable to the production of olefine oxides, suitably at 150-400 DEG  C. and atmospheric, reduced or raised pressure in the presence or absence of a catalyst but preferably in the presence of a silver catalyst, with or without a promoter.  In the examples, (1) ethylene is oxidized with air or oxygen in the presence of a small proportion of lead tetraethyl and in the absence of a catalyst; (2) a mixture of ethylene and air containing a small proportion of ethylene dibromide is passed through a silver-coated tube kept at 350 DEG  C.; in place of ethylene dibromide, ethylene dichloride, benzene, xylene, aniline or ethyl alcohol may be used.  The Provisional Specification refers generally to the addition of anti-knock materials in catalytic oxidation processes, and specifies, as anti-knock materials, compounds of heavy metals with carbon monoxide, such as iron pentacarbonyl, and finely dispersed heavy metals such as lead or iron.  It includes an example in which a mixture of cracked gases, air and iron pentacarbonyl is led over iron oxide to yield unspecified oxidation products, and refers also to the production of phthalic anhydride from naphthalene.

Abstract: 182,431. British Thomson-Houston Co., Ltd., (Assignees of Kingdom, K. H.). July 1, 1921, [Convention date]. Vacuum tubes; low-pressure metallic-vapour apparatus.-The current carrying capacity of a two-electrode valve, having a highly exhausted container, is increased by confining any positive ions produced to the region of the space charge by means of screens or by shaping the anode. In one arrangement, Fig. 1, two screens in the form of plates 14, 15, having apertures through which the filament cathode 7 passes, are mounted on insulating supports 16, 17 so as to close the ends of a cylindrical anode 6 spaced by helical springs 12 from the container walls. The anode and the plates 14, 15 may be maintained at the same or different potentials. The plates may be supported from the ends of the tube, or may be secured to the anode by welding at the edges. In another arrangement, Fig. 3, conductors 3.5, mounted on a ring 36 adjacent the anode 6, project towards the cathode 7 without touching it. The anode is mounted on a two-pronged glass support 37 having stiff wires 39 touching the container wall so as to steady the structure. In another arrangement, no screens are used, the cylindrical anode having a length twelve times its diameter. The electrodes are preferably deprived of occluded gas, and the container is exhausted to such a degree of vacuum, for instance below one-tenth of a micron, that the effect 'of gas ionization in reducing the space charge is evident only when the anode screens are charged to trap positive ions; or a small quantity of mercury vapour, or of a gas such as argon, helium, nitrogen, or hydrogen may be admitted. Specifications 28413/13 and 100,104 are referred to.

Title: Safe load indicator for hydraulically luffed boom of civil engineering machine
Inventor: MILSOM HUBERT
IPC: B66C23/90
Filed: 1967-01-13
Abstract: 1,133,756. Safe load indicators. PRIESTMAN BROS. Ltd. 31 Oct., 1967 [13 Jan., 1967], No. 2013/67. Heading B8B. [Also in Division E1] A civil engineering machine has a boom which is luffable by a double-acting hydraulic ram 1, and a safe load indicator comprising a pivoted lever 15 acted upon by pistons 8, 13 which are subject to the pressures in the respective ends of the ram and which produce a torque on the lever corresponding to the differential reaction sustained by the ram in supporting the boom and any load suspended therefrom, the lever 15 being also loaded by means of a spring 27 subject to pressure from a cam-operated lever 21 in dependence upon the boom angle so that when the reaction sustained by the ram exceeds that necessary to support the boom and a safe load the lever 15 is moved to operate a microswitch 18 energizing an alarm such as a lamp or a bell. Downward movement of the boom is limited by a constriction restricting the passage of fluid through the line 4. The ends of the ram are respectively hydraulically connected to the pistons 8, 13 by lines 7, 12, and the pistons act on the lever 15 at points spaced from the lever pivot 16 by distances proportional to the pressure areas on either side of the ram piston 2. The microswitch 18 is adjustable about a pivot 19 by a screw 20. The lever 21 is pivoted at one end at 22 and carries at its other end a roller 23 engaged by a cam 24 which is turned about a centre 25 by an arm 26 as the boom is luffed. The spring 27 acts between the levers 15, 21 so as to load the lever 15, the load depending upon the movement of the lever 21 and therefore upon the boom position. The point at which the piston 13 acts on the lever 15 is adjustable towards or away from the pivot 16. The lines 7, 12 may include capillaries to avoid any momentary pressure increase from inadvertently operating the alarm. Although the safe load indicator as described is mechanically operated it may alternatively be operated electrically, hydraulically or pneumatically.
