Title: Improvements in mechanism for rewinding webs of paper, fabric and the like
IPC: B65H18/10
Filed: 1931-02-13
Abstract: 363,549. Winding webs. VICTORYKIDDER PRINTING MACHINE CO., Ltd., Birkenhead, and WILSON, H. W. V., Roslyn, Bertram Drive, Meols, Cheshire. Feb. 13, 1931, No. 4583. [Class 100 (i).] In a rewinding-mechanism for webs of cloth, paper, fabric, &c., of the kind having a frictional drive, the rewinding-spindle is carried by arms moving in accordance with the diameter of the roll and automatically controlling a friction disc movable between two parallel friction wheels, whereby the speed of rotation of the rewinding-spindle is varied so as to maintain uniform tension in the web. The roll spindle 3 is carried on two arms 4 pivoted at 5, the weight of the roll, arms, &c. being just more than counterbalanced by a spring 20 attached to an arm 19. A rotatable stop 1 bears on the surface of the rewound material so that, as the diameter of the roll increases, the spindle 3 is forced downwards. On an arm 6 fixed to the spindle 3 is pivoted a rod 7, the other end of which is pivoted to an arm 8, which is pivoted at one end 9 to the framework and engages at the other end with a collar 10 fixed to a sliding bar 11. A rotating friction wheel 14 is mounted on the bar 11 and the edge of the wheel 14 engages with the inner faces of two discs 15, 16 mounted parallel but not coaxially on the frame. The disc 15 is driven at constant speed and the disc 16 is connected by spur gearing to the spindle 3. Thus, as the spindle 3 is depressed, the wheel 14 moves towards the centre of the disc 15 and towards the periphery of the disc 16 so that the speed of rotation of the spindle 3 is accordingly reduced.

Title: Improvements in or relating to the production of phosphate coatings
IPC: C23C22/36
Filed: 1948-02-17
Abstract: In a process for the production of corrosion-resistant, paint-holding coatings on metals by the use of a general purpose solution effective on aluminium, iron and zinc surfaces, surfaces composed solely or preponderatingly of only one or two of these metals are subjected to the action of a hot aqueous solution containing soluble compounds of each of these metals, a dihydrogen phosphate, a complex fluoride and an oxidizing agent, the solution being maintained by adding thereto a soluble compound of the metal or metals absent from or only sparingly present in the surfaces undergoing treatment.  The complex fluoride is preferably a fluoborate, added as such, or as boric acid and sodium bifluoride; the phosphate is zinc dihydrogen phosphate; and iron or aluminium is added as ferrous sulphate or aluminium nitrate. Specification 655,070 is referred to.

Title: Improvements in and relating to sights for rifles and like firearms
IPC: F41G1/387
Filed: 1924-02-25
Abstract: 224,433. Packard, R. G. Feb. 25, 1924. Sights.-A telescope sight having a vertically and laterally adjustable graticule, is clamped to a carriage which is removably but rigidly secured to the gun by undercut wedge surfaces forced against corresponding surfaces on the gun by pressure multiplying mechanism. As shown, the carriage comprises a flat bar 11 having brackets 12, 12<a> in which the telescope 15 is clamped. The bar has dovetail projections 19, 18, Fig. 2, at front and rear, fitting into correspending recesses in the breech-frame 2, Fig. 5, or in a plate fixed thereto. The sides of the projections are non-convergent in the direction of slide so that there is no small-angle wedging action. The rear projections 18 are undercut at the front to form a transverse wedging surface 26, Fig. 2, engaging a corresponding surface in the frame. These surfaces are forced together by pressure multiplying mechanism comprising a rotatable cam 32 eccentrically mounted in a rotatable bearing 50. The cam 32 has a flat part 32a, Fig. 11, and is rotated by a handle 38 to set the wedging surfaces together, and the bearing 50 is then rotated by a worm 51 to apply great pressure. The telescope is preferably offset from the medial plane of the gun to such an extent that it is in alignment with one eye while a set of central sights is in alignment with the other. The ad. justable graticule comprises a primary carriage 103, Fig. 12, for vertical adjustment and a secondary carriage 106, slidable in the primary carriage, for horizontal adjustment. Each carriage is adjusted by a thrust screw 70, 90 and a restoring spring 113, 110. Each thrust screw has an exterior head 68, 88 rigid therewith and a head, adjustable, for zeroizing, carrying a spring detent 63, Fig. 2, 83, Fig. 9, adaped to engage notches 62, 82 forming a stationary scale. The adjustable head is secured to the fixed head in the desired zero relation by locking screws 99 engaging holes arranged in vernier relation in the two heads respectively.

Title: Improvements in and apparatus for carrying out chemical or physical processes involving finely divided solids and gases
IPC: B01J8/36
Filed: 1956-02-20
Abstract: <PICT:0796200/III/1> Fine-grained solid particles are fed to a fluidized bed from above and through the surface thereof whilst maintaining a gas pressure at the point of entry of said material higher than that above the remaining parts of the fluidized bed.  The method may be applied to sulphide ore roasting, catalysis or heat exchange processes. As illustrated in the Figure, an ore-roasting furnace 1 lined with refractory ceramic contains a fluidized bed 2 supported upon a grid 3 through which air is blown from wind boxes 4 and 5.  An ore such as pyrite is supplied to the furnace from hopper 8 by means of plate feeder 12 and falls through a zone 6 separated from the main gas collecting zone 2a by means of a partition 13 having openings 7 which can be closed by inserting bricks if desired, and a serrated lower edge.  The zone is said to be in limited communication with the atmosphere through the unavoidable leakiness of the plate feeder.  Air is introduced through a regulating valve 14 into the chamber 6 to maintain the slight excess pressure over that in the chamber 2a.  Gases of the same composition as that introduced from the wind boxes and/or inert gases may be supplied above the fluidized bed.  The roasted material is discharged through an outlet pipe 19: if desired air may be passed in through inlet 20 to assist the withdrawal.  The wind chambers 4 and 5 may also be provided with outlets 18 for discharging ore.  A bank of cooling elements 17 serves to maintain the roasting temperature and at the same time produce steam.

Abstract: 788,770. Shaping glass. PITTSBURGH PLATE GLASS CO. Feb. 20, 1956 [March 2, 1955], No. 5146/56. Class 56. In a method of preparing glass sheets for lamination into curved shapes by simultaneously subjecting the sheets to glass softening temperatures while mounted on a single glass shaping mould, the sheets are subjected to different thermal histories so that they have different internal viscosities before they are bent. Preferably the upper sheet 10, which may be thicker than the lower sheet 12, is first tempered to reduce its viscosity and is then mounted over the sheet 12 on the shaping mould M, a suitable separating or parting material 14 such as mica or diatomaceous earth being applied to the upper surface of sheet 12. For sheets of equal thickness, a partial temper may be imparted to the lower sheet and a more severe temper to the upper sheet. For the curved windscreen 20 comprising sheets 22 and 26 of glass and thermoplastic transparent interlayer 24, sheet 22 will be tempered if a male mould is used, but sheet 26 if a female mould is used, the tempering ensuring even and intimate contact between the sheets 22, 26 over the varying curvatures 30 and 32 and over similar varying curvatures at right angles to the section shown.

Abstract: In a material reduction mill comprising a drum mounted for rotation on a substantially horizontal axis and having a diameter length ratio of at least 2 : 1, inwardly-projecting crusher bars on its cylindrical wall, and circular keying liners extending inwardly from its end walls and defining a keying zone in the space between inwardly extending apices of the liners and the cylindrical wall of the drum, a synthetic charge of reduction media is provided having a volume inclusive of voids which is from about 10% to about 45% of the volume of the keying zone.  The synthetic charge may be composed of steel balls graduated in size from about one inch to about six inches in diameter.  Use may be made, however, of higher specific gravity reduction media, e.g. tungsten carbide.  Alternatively, reduction media composed of metals lighter than iron may be used or use made of a pebble charge having a specific gravity not materially greater than that of the mill feed.  Further, the synthetic charge may be composed partly of large lumps of feed material and partly of reduction media composed of pebbles.  The metallic reduction media may be of non-spherical shape.
