Filed: 1965-05-24
Abstract: 1,141,797. Printing apparatus. METRODE PRODUCTS Ltd. 11 May, 1966 [24 May, 1965], No. 21920/65. Heading B6C. An apparatus for printing on the curved surfaces of cylindrical objects comprises a conveyer, a printing cylinder adjacent the conveyer and connected to drive mechanism for rotating the cylinder, and a photo-electric device for sensing the arrival of each object at a position adjacent the printing cylinder and arranged to actuate the drive mechanism to cause the cylinder to rotate through one revolution. The object is rotated at the same peripheral speed as the printing cylinder during the printing operation by friction surfaces 23 which form part of the readily detachable printing plate 19. The peripheral speed of the cylinder is appreciably faster than that of the conveyer whilst the printing plate is inked from a fountain 22 by rollers 21 and 20. The cylinder may accommodate a plurality of circumferentially spaced plates 19, the drive mechanism being so adjusted that the cylinder only rotates that part of a revolution corresponding to the actual number of plates carried.

Abstract: 636,963. Knitting-machines. FORD, F. J. Aug. 8, 1947, No. 22040. Convention date, June 14, 1940. [Class 74 (ii)] A circular warp machine forms a fabric comprising successive courses of warp knitted loops, ribbed weft knitted loops and plain weft knitted loops, which may enclose an unknitted roving to form a padded fabric. The machine comprises a fixed dial 34 and cylinder, the dial 34 holding in alternate series, needles 132 and warp yarn guides 128, Fig. 18. The machine is. divided into sections, each having an identical dial cap sector and three cylinder needleraising cams 136, 138, 140, Fig. 14, combined with spring-mounted lowering cams 144. The dial cap sectors advance for knitting, first the guides 128, then the dial needles 132, both being then withdrawn for a period. Yarn supply.-Warp yarns 62 are passed through guide rings 60, 66, Fig. 1, to the guides 128. The roving 88 is contained in baskets 94 carried on the needle camring 72, one per machine section, the roving being led to guides 84 to pass through the lowered cylinder needles 76 to the interior of the cylinder. Guards 114, Fig. 10, keep the roving clear of the cylinder needles and a guard 118 keeps the previous course of roving clear of the incoming course. Yarns for weft and rib knitting are taken from bobbins 104, revolving with the cam ring 72, Fig. 1, to guides 108, Fig. 10, one guide supplying yarn 106, Figs. 24, 25, to dial and cylinder needles together and the other, yarn 107, to the cylinder needles 76 only. The warp yarn guides 128 are each formed with a spring member 162, Fig. 18, which opens out when the guide is advanced, to spread the yarn, and closes against the guide as the latter is drawn into the trick. Driving mechanism.-A shaft 16, belt driven, turns the cam ring 72 through mitre gears 26. The dial cap is driven from the shaft 16 by a shaft 22 and gears 24 through a belt 20. Knitting operation.-The warp yarn 62 extending from an advanced guide 128 to the knitting around the previous course of roving 88, is taken by a needle 76 raised by the cam 140, and drawn across the entering roving to form a loop with the plain weft thread 107 extending between the needle 76 and the previous course, Fig. 22. A needle 76 raised by the cam 138 co-operates with an advanced dial needle 132 to draw a newly laid yarn 106 through the last formed loop, the old yarn 106 extending from the dial needle 132 to the old roving course being cast off. The needle 132 and guide 128 are now withdrawn and a needle 76, raised by the cam 136, receives the plain weft yarn 107 and draws it through the previously formed loop of 106 yarn in front of the roving.

Abstract: 155,348. Jones, A. Seymour-, and Turner Tanning Machinery Co. Sept. 11, 1919. Splitting.-Relates to resilient work-supports of the kind comprising sectional elements bearing against a hollow flexible body containing fluid under pressure, and applicable to fleshing or other rotary-tool machines or to belt-knife splitting- machines. The invention comprises an arrangedment embodying a cylindrical metal casing 1 adapted to be attached rigidly to the frame of the machine and containing a rubber or other tube 2 inflated to fill the casing. An opening 3 is formed along one side of the casing to expose the tube 2, the casing being formed with side walls 4 with longitudinal recesses 8. Bearing against the tube and guided between the walls 4, with lugs 7 engaging the recesses 8 therein, are a number of blocks or sectional elements 9 arranged side by side and forming the resilient work support. As shown in Fig. 3, the blocks 9 are formed with flanges 11 and serve as carriers for the actual work-supporting elements 10 which may be of hard rubber, fibre, hard wood, white metal, &c. and are renewable. When made of rubber &c., each section 10 is reinforced by a strip 17 of sheet metal. The rounded face 12 of the work support is shaped to give a small surface contact with the hide when pressing it against the tool. A modification is described in which the sections 9. instead of serving as carriers, are extended and rounded to form the actual work-supporting surfaces. Cutting or chafing of the tube 2 is obviated by one or more layers 16 of duck, canvas,. thin leather, &c. cemented to the tube, or interposed loosely or fastened to the casing on one or both sides of the opening. The casing is closed by end-plates 18, Fig. 5, with extensions 19 to prevent displacement of the sectional elements. The recesses 8 in the side walls 4 may be lubricated by fat or oil, in which case the ends are closed. The tube 2 may be formed with a flanged end compressed between the end plate 18 and the casing, the end plate also being formed with a boss which enters the end of the tube. An alternative form is described in which the tube end is nipped between a tapered boss on the cover-plate and a tapered opening in the casing. A connexion 24 on the coverplate 18 serves for inflation of the tube 2 which may be subsequently sealed or closed, or the interior of the tube may be permanently connected with means for maintaining a constant internal pressure, such as described in Specifications 4681/07 and 132,843, [both in Class 76, Leather]. Specifications 6751/11 and 27766/11, [both in Class 76, Leather], also are referred to.

Title: Hoist control mechanism
IPC: B66B1/52
Filed: 1954-08-03
Abstract: 796,325. Winch control. LOGAN, H. H. Aug. 3, 1954 [June 10, 1954], No. 22468/54. Class 78 (5). A variable-depth winch control apparatus for a mine comprises a rotatable depth control, driving means for driving the control in timed relation with the winch drum, adjusting means for altering the phase relation between control and drum, and preventing means for preventing an inadvertent alteration of the phase relationship. As shown, shaft 50 is driven from the winch drum (not shown), said shaft driving the cam 52 of a cam-operated Lilly hoist control through sungear 54, planet gears 56 carried by planet carrier 58, and ring gear 60 fast with cam 52. The angular relationship between drum and cam may be altered to vary the end limit of the wind by manually varying the position of the planet carrier, which variation is effected normally from shaft 69 through gearing 68, 66. To prevent undesirable manual adjustment a safety device is incorporated, comprising stepped cam 72 and cam 83, cam 72 being fast with planet carrier 58 and cam 83 being driven from shaft 50 through gearing 86, 89, 91, 92 so that both cams rotate at the same speed. The two cams are connected respectively by pawl 75 and follower 85, the two latter being fixed on the same shaft 78. The two cams thus interact to prevent an undesirable contingency, viz. the possibility that when the cage is at rest at its predetermined lower limit, a manual adjustment should be attempted to change that lower limit to a stop level above the said predetermined lower limit, thus throwing the Lilly control out of phase. The selector 37 (Fig. 7) which effects the manual adjustment of cam 52 of the Lilly, hoist control, is operated by handle 124 (Fig. 6) which rotates shafts 120 and 115, the position of the cage being indicated by pointers 114 and 123 and the shafts carrying differently-orientated cams 127 and 128 which operate visual signals at the respective levels. The output shaft 70 transmits movement to the input shaft 69 of the control (Fig. 3).

Abstract: 797,292. Valve circuits. DECCA RECORD CO., Ltd. July 20, 1956 [Aug. 4, 1955], No. 22518/55. Class 40 (6). Regeneration is applied to a travelling-wave tube through two directional couplers to which the input and output connections are made. The input is coupled via arms 1, 3 of the directional coupler 11 to the travelling-wave tube 10, the output of which is taken via arms 3, 2 of the directional coupler 14. Regeneration is provided by arms 3, 1 of coupler 14, a phase-shifter and arms 2, 3 of coupler 11, the phase of the feedback being adjusted to be in phase with the input. The coupling between arms 1, 3 of the couplers should be less than that between arms 1, 4. Matched loads 13, 15 may be connected to arms 4, but if the loss between arms 2, 3 of coupler 11 I is less than that between arms 1, 3 of coupler 14 by an amount equal to the gain of the tube 10, no power is absorbed and the increase in gain is numerically equal to the loss between arms 1, 3 of coupler 11. In a modification (Fig. 2, not shown) a frequency selective filter and a ferrite gyrator are connected in cascade with the phase shifter; the gyrator tends to prevent any circulation in the wrong direction.

Abstract: 415,884. Bending angle &c. bars. STEPHEN & SONS, Ltd., A., and STEPHEN, J. G., Linthouse, Glasgow. Aug. 12, 1933, No. 22522. [Class 83 (iv).] A pair of angle or like profile bars are bent while clamped back to back, forces acting on the flanges serving to deform these prior to the final bending of the bars which is effected by forces at three spaced points, the forces on the flanges being maintained during the latter operation to preserve the bevel given to the flanges. A pair of bulb angles 7a, Fig. 1, is arranged against bolsters (not shown) and acted on by a divided pressure ram 13 the jaws 5 and 6 of which are loosely pivoted about the pin 24. The pressure ram 13 bears against heel portions 12 on the jaw members closing them in so that the parts 14 hold the angles together while the projecting ends 8, 9 of the jaws deflect the flanges of the angles, the part 10 of the ram subsequently contacts the angles and effects the longitudinal bending ; a.wedge 11 enables the part 10 to be adjusted so as to vary the angle given to the flanges or the parts 8, 9, 10 might act simultaneously in which case the flange angles would not be altered. The gripping parts 14 may be automatically released on backward movement of the ram by toggle mechanism 41. A modified arrangement, Fig. 3, comprises two polygonal discs 26, 27, carried by a pressure ram and adjustable towards one another by screw and nut gear 28, 32. The discs are bevelled to various angles around their peripheries and they may be indexed by a pin 40 so that a pair of angles clamped back to back may have the flange angles altered and may be bent longitudinally A rod 35 and handwheel 36 enable the height of the discs to be adjusted.

Abstract: 410,459. Photographic sensitive materials. VIGANO, R., 12, Via Porro Lambertenghi, Milan, Italy. Aug. 12, 1932, No. 22601. Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 13, 1932]. [Class 98 (ii).] The light-sensitive material is incorporated in a transparent support, e.g. of celluloid or paper, or of cellulose xanthate or a derivative or homologue thereof such as viscose, viscoid, sulphocellulose, cellophane or biophane. The sensitizing is performed by bath treatment, and if the support is non-absorptive it is rendered absorptive by adding a softening agent, e.g. alcohol in the case of a celluloid support, to the first treating bath. As applied to silver sensitizing, the support is treated in succession with (1) a preparatory bath of chlorides, bromides or iodides or a mixture thereof, and, after drying, with (2) a pure or ammoniacal bath of silver nitrate, which saturates the salts taken up from the preparatory bath, and (3) a conversion bath of chlorides, bromides, and iodides which precipitates sensitive silver halide in the body of the support. The support is finally washed. The preparatory bath (1) may alternatively contain carbonates, phosphates or other basic salts. When film material is used, it may be cleaned with caustic alkali before sensitizing. The support may consist of a single layer of cellulose xanthate, or of two or more adherent layers.
