Title: Magnetic Reel Holding Device
IPC: B65H54/44
Filed: 1967-01-12
Abstract: 1,170,004. Magnetic reel holding device. GENERAL CABLE CORP. 12 Jan., 1967 [1 March, 1966], No. 1675/67. Heading D1J. A reel 16 is held in position on a spindle 10, which is rotatably driven through shaft 12 by power means 19, by means of at least one magnet 40 carried by a frame 32 connected to the spindle assembly and extending perpendicular to the shaft 12. An abutment 18 on the spindle limits rearward movement of the reel, and it is in this limiting position that the magnet contacts the rear face of reel 16. Preferably a plurality of magnets are angularly spaced around the spindle, each magnet being carried in a compartment 36 of housing 32 by means of a screw 42. The dimensions of the magnet, the compartment, and the screw allow for limited movement of the magnet in any plane for alignment with the reel face. Radially extending, angularly spaced ribs 50 on the reel face contact with housing 32 to limit slipping during rotation of the spindle in the case of the magnetic force being insufficient to prevent slipping.

Title: Method of making tin plate resistant to oxidation
Inventor: BOGGS WILLIAM EMERSON
IPC: C23C26/00
Filed: 1962-01-17
Abstract: A method of making electrolytically deposited tin, backed by a low carbon sheet steel, resistant to oxidation comprises depositing one of Al, Mg, Ca, Ga, Cr or Ge on to the tin surface and carrying out a remelting step.  Ge must be applied by vapour deposition but the others may be applied by vapour deposition or by electrolysis.  After the remelting step the tin plate is cooled and then preferably maintained below the melting point of tin at a temperature of 300-425 DEG F. for from 2 to 10 minutes under oxidizing conditions.  The electrolytic deposition of Al, Mg, Ca, Ga and Cr is preferably carried out using an anhydrous ethanolamine solution of a salt, preferably chloride, of the desired metal.  Effective percentage ranges for the added elements are as follows: Al 0.001-0.5%, Mg 0.0005-0.5%, Cr 0.006-0.5%, Ga 0.006-2.5%, Ca 0.006-0.5%, Ge 0.05-1.0%.

Abstract: 997,570. Water extraction in paper-making machines. KIMBERLY-CLARK CORPORATION. Jan. 18, 1962 [Feb. 3, 1961], No.1897/62. Heading D2A. [Also in Division F4] The removal of water from the web in a Fourdrinier paper-making machine is facilitated by blowing steam on to the web opposite to or in front of a water removal device. The steam is caused to inspinge on the web in discrete jets at a velocity between 10 and 600 feet per second and to emerge from a perforated plate positioned not more than 2 inches from the web,the smallest diameter of each opening being at least <SP>1</SP>/16 inch. Steam which may be superheated may be applied from shrouds 49, 50, 51, 52 located adjacent the couch roll 12, last vacuum box 14, felt suction box 35, and press rolls 39 respectively. In a tissue machine incorporating a "Yankee" dryer drum, a "steam shower" may be provided immediately prior to the web's passage from the felt to the dryer drum. The "steam shower" comprises a stack of square section pipes provided with staggered steam discharge slots. The same machine may incorporate steam shrouds similar to shroud 49 formed to be located in proximity to a couch roll. Steam enters this shroud through a pipe 56 and leaves through openings 59 in a plate 58. Insulating material 55 is incorporated in the shroud. In order to provide soaking times, the shrouds or "steam showers" may be located at predetermined distances in front of the water extraction devices.

Abstract: 172,542. Rigby, R. Jan. 12, 1921. Clutches, c l a w ; operating clutches.-In devices for enabling a kinematograph film to be driven in either direction, comprising clutches of the kind in which an arm 16, Fig. 3, is engaged by driving pins 22 on a second arm 17, the pins are spring-mounted so that injury to the clutchoperating device may be prevented in the event of the pins bearing on the flat face of the arm 16. One arm 16 is carried by each of the two parallel spool-supporting spindles 15, each of the corresponding arms 17 is movably axially without rotation in relation to a sprocket wheel 20 for clutching and declutching, and the two clutches are operated simultaneously in reverse directions through a lever 24 fixed on a spindle 25. The two sprocket wheels 20 are driven by a chain from a sprocket wheel 33, Fig. 4, which is frictionally driven from a spindle 31 through a lost motion connection. Upon a reversal of the drive this connection allows the spindle 31 to rotate through a limited angle in relation to a member 37 upon which the wheel 33 is mounted, and owing to a quick-pitch screw connection between the member 37 and the spindle 31 the latter moves axially and, through an arm 28 fitted with a ball 29 engaging a groove on a collar 30 of the spindle, operates the spindle 25 to open one clutch and close the other.

Title: Electric switching devices using magnetic particles

IPC: H01H9/42
Filed: 1958-01-23
Abstract: 863,819. Magnetic switches. TANN CORPORATION. Jan. 23, 1958, No. 2351/58. Class 38 (5).  An electric switch has a member having a cavity, magnetizable particles of different resistance in said cavity, magnetic means movable relative to said member across at least a portion of said cavity, and a circuit completed by said particles when at least some are caused to move into engagement by said magnetic means. The particles or balls may be of nickel-iron alloy having low remanence and coercive force. In Fig. 1 an insulating member 35 movable about a pivot 36 between two magnets 46 has a cavity 38 with an extending portion 39. Magnetic particles 42 are retained in a ring 41 in the circular part of the cavity and other particles 43 of higher resistance occupy the portion 39. As the member 35 is moved the tip of the portion 39 comes between the magnets 46 and the particles 43 are aligned to complete a circuit between the magnets with a high resistance so as to limit the initial current. As the main part of the cavity 38 comes between the magnets particles 42 of lower resistance are aligned. A snap-action is achieved by two fixed magnets 31 with like poles 34 together and a magnet 37 on the member 35 with a pole on the edge of the same polarity as those at 34 so that it is repelled thereby. In Figs. 4 and 6, the magnetic bias is provided by three magnets 61 on the pivoted cavity member 54 which are repelled by three magnets 59 on a copivotal member 58 having an operating handle 56. In Fig. 7, the snap-action is achieved by a compression spring 76 between the cavity member 68 and a dolly 71, pivoted at 73, 72, respectively. Fig. 10 shows a crosssection of an arrangement similar to Fig. 7 where the particles 42, 43 are aligned between magnets 67. The spring 76 is mounted between the member 68 and a projection 75 from a sleeve 77 fixed to an operating-shaft 78. In Fig. 22, magnetic rods 166 pass through a non- conducting body 165 to one side of the cavity 168 and have the same polarity as the ends of rods 169 at the other side of the cavity. The approach of a magnet 170 reverses the polarity of the rods 169 and the particles form conducting chains between the rods.
