Title: Information band winding apparatus
IPC: G11B15/56
Filed: 1959-11-24
Abstract: 873,328. Automatic control systems. FERNSEH G.m.b.H. Nov. 24, 1959 [Nov. 25, 1958; Feb. 3, 1959], No. 39819/59. Class 38 (4). Tape 1 is passed from spool 2 over rollers 9, 10, and drive-sprocket 11 to spool 12, the rollers forming the tape into loops the size of which is kept substantially constant. For this purpose, the spools are driven by repulsion motors 13, 14, having brush-gear adjusted in accordance with the positions of the rollers 9 and 10. Thus, if the loop which supports the roller 9 is shortened so that the roller moves from a central position, the motor 13 is started in a direction such as to restore the loop to its mean size and at a speed which increases as the distance of the roller from its central position increases. When the length of loop increases, the motor is caused to turn the spool in the opposite direction. The roller 9 may be carried on an arm which is slotted to engage with the end of a brush-control arm, Figs. 2 and 3 (not shown). The brush-gear may be associated with a cam to ensure strict proportionality between deviation of the roller and speed of the spool motor, or the cam may provide stepped control of the speed. When the roller 9 drops below a lower limiting position reached in normal operation, a switch is actuated to disconnect the spool motors and the motor driving the sprocket 11. In another arrangement the loop is formed by two rollers on opposite ends of a rocking arm which is secured to a shaft coupled to the brush-gear. The rocking arm is biased in a direction to increase the length of the loop by means of a spring attached to a flexible member wrapped around a cam secured to the shaft, Fig. 4 (not shown). The shape of the cam is such as to produce constant tension in the tape over a wide range of angular movement of the shaft. To prevent hunting the spool motors are coupled to air brakes having fans which are driven at high speed from the shafts of the spool motors.

IPC: C10G25/03
Filed: 1962-10-22
Abstract: In an absorption-desorption process, straight-chain hydrocarbons are separated from hydrocarbon mixtures using 5<\>rA molecular sieves wherein a fresh sieve (i.e. one that has not previously been subjected to an absorption-desorption sequence) is treated prior to the desorption step with a free-oxygen containing gas at elevated temperature in the presence of hydrocarbons but below that temperature at which the sieve structure will be damaged. The hydrocarbon may be adsorbed within the sieve pores or held interstitially between sieve particles. The sieve may be treated with a hydrocarbon fraction and subsequently an oxygen-containing gas. The separation process which may be isothermal, may include absorption, purge and desorption stages and the oxygen treatment may be carried out immediately on to the first absorption stage or purge stage or during the purge stage.  The oxygen-containing gas has not more than 2% but preferably 0.5 to 1.0% of oxygen and may be diluted with nitrogen.  In a specific embodiment n-paraffins are separated from a petroleum fraction boiling 230-300 DEG  C. in a three-stage process.ALSO:In an absorption-desorption process, straight-chain hydrocarbons are separated from hydrocarbon mixtures using 5 molecular sieves wherein a fresh sieve (i.e. one that has not previously been subjected to an absorption-desorption sequence) is treated prior to the desorption step with a free-oxygen containing gas at elevated temperature in the presence of hydrocarbons but below that temperature at which the sieve structure will be damaged.

Abstract: 929,304. Jigging conveyers. CHAIN BELT CO. Nov. 27, 1959, No. 40468/59. Class 78 (1). A jigging conveyer comprises a casing 21 (Fig. 1) in the form of a multi-sided prism which is supported from a base 23 by hinged inclined links 24 or helical springs 25. The base 22 of the casing is vibrated by a crank-shaft 27 mounted in the base 23 through a connecting-rod 26 and a lever 31. One end of the lever is pivoted to a support 32 mounted on the base 22 and the other end of which is connected to this base through a shock-absorber 33. The casing contains a series of porous trays 36 forming the conveyer surface each of which has a radial slot 37 to allow the material to fall through on to the tray below. Treating medium is introduced through a pipe 40 into a centrally-disposed cylindrical manifold 41 from which it passes through ports 42 located just above each tray. The manifold may be connected by a resilient strut 45 to a fixture 46. When it is not desired to apply fresh treating medium to the material on each tray, the medium is discharged from the manifold only through ports at its lower end. The trays may be imperforate in which case the material passes through a shoot from a tray to the next but one tray below. In a modification any particular portion of the medium after passing through one of the porous trays is discharged at once from the system instead of being allowed to flow upwards through the trays above. In the modification shown in Figs. V and VI (not shown)'a single porous conveyer deck 114 isprovided on which is mounted a spiral guide. The material, which enters through a shoot 110, drops on to a divider 111 at the centre of the spiral and after passing around the spiral is discharged through a shoot 116. Infra-red lamps 129 may be mounted on the hood 118 to irradiate the material. This structure may be modified by making the deck imperforate and providing a discharge for the treating medium immediately opposite to the inlet 117.
