Title: Systems for controlling the length of a loop of tape in a buffer chamber
IPC: G11B15/58
Filed: 1970-11-16
Abstract: 1280590 Automatic tape control AMPEX CORP 16 Nov 1970 [17 Nov 1969 (3)] 54477/70 Heading G3R Signals proportion to variations of the length of a loop of tape near upper and lower limits between reel and capstan or other drives are applied, with signals representing the direction of movement of the tape on each side of the loop, to a logic circuit controlling the speed of the reel to maintain loop length long or short according to the direction of movement of the tape. In Fig. 1, magnetic tape 10, for recording and reproducing digital information, is stored on reels 12, 14 and moved intermittently in either direction past a record/reproduce head 16 by a capstan 20 driven by a motor 22 controlled by signals from a data processing system. Buffer loops of tape between each reel and the capstan are formed in chambers 30, 32 in which the pressure is reduced by a vacuum source 36. Air bearing guides 34 and small buffer pockets 38, 39 are provided between the buffer loops and the record/reproduce head. If the loop shortens in either chamber so as to expose progressively an upper elongated photo-cell, such as 46, to illumination from lamps 50-52, a signal is applied through an amplifier 60 and summer 82 to proportionally slow down or speed up a motor, such as 28, driving one of the reels so that the length of the loop is restored to the lower limit of the photo-cell. In a similar manner if the loop lengthens to below the top of a lower photocell, such as 48, a signal is applied through an amplifier 64 to restore the loop to the upper limit of the photo-cell. Signals, e.g. from tachometer generators, corresponding to the directions in which the reel and capstan motors are driven, and thus the directions of tape movement on each side of the loop, are applied to a transistor or relay logic circuit such as 62 so that when the bottom of the loop is between the photo-cells and both sides of the loop are moving upward or downward, the appropriate reel drive motor is braked to oppose the movement of the loop. Extreme deviations of the loop are detected by sensors 42, 43 and the reel drive motor current may also be limited.

The biasing means includes pins 114 mounted in the piston 56 and urged upwardly by springs 119. It also includes residual air under pressure in a chamber 70 between the piston 56 and the control valve 72. Further pins 120 acted on by springs 130 bias the control valve 72 to the open position. Opening of the exhaust control valve 72 is effected by an actuator 94 connected to the ram plate 14 by a screw 92 and rod 86. Washers 106 can be selectively removed from above actuator 94 and placed adjacent the bottom wall 98 of the actuator (Fig. 5, not shown) so as to vary the length of stroke of rod 86 prior to the opening of exhaust valve 72 by actuator 94. Springs 36 are provided for returning the ram plate 14 to its raised position.

Filed: 1974-12-20
Abstract: 1475090 Decomposition of water KERNFORSCHUNGSANLAGE JULICH GmbH 20 Dec 1974 [29 Dec 1973] 55258/74 Heading C1A Water is converted into H 2  and O 2  by reacting a gas mixture containing steam and SO 2  with an oxide or oxides of one or more of the metals Mn, Fe, Co, Ni, Zn and Cd to produce metal sulphate and H 2 , and separating off the H 2 , the metal sulphate is thermally decomposed to form metal oxide, SO 2  and O 2 , the O 2  being separated off. The process is preferably operated in a cyclic manner, in which the SO 2  produced by the decomposition of the sulphate is mixed with more steam and again reacted with the metal oxide. Suitable temperatures for the formation of the sulphate lie in the range 200‹ to 400‹ C., while the decomposition of the sulphate formed is undertaken typically in the range 700‹ to 1,000‹ C. Advantageously, the metal oxide reacted to form the sulphate is in a highly dispersed form; the metal oxide may be in the form of a thin layer applied to a highly porous solid carrier material containing SiO 2 .

Abstract: 1,208,746. Optical instruments. D.P. BUSHNELL. Dec. 12, 1967 [Jan. 26, 1967], No. 56323/67. Heading G2J. An optical instrument, e.g. binoculars, comprises an image erecting system of 4 mirrors 16, 17, (18), 19 located between objective 15 and eye lens 40 systems, the combination of lenses and mirrors being held in place by a foamed plastics support 43 which was moulded about said combination. The objective and eye lenses are themselves in mountings which are initially aligned with a stepped plate 26 having orifices 27, (28), 29 for the light path through the binoculars, the foamed plastics supported being moulded into place after alignment. The foamed support 43 not only encloses the lens mountings but also is in contact with the back faces of the mirrors. As a finish the moulded support can be given a plastic covering 44. A negative lens 34 is mounted between the mirrors and the eye lens in a ferromagnetic ring 35 slidable inside the eye lens mounting 33. A magnetic ring 50 mounted externally of mounting 33 and concentric with ring 35 provides a focusing means, since movement of magnetic ring 50 along mount 33 causes movement of lens 34. In an alternative embodiment the four mirrors are replaced by a pair of Porro prisms, the foamed plastics support being moulded about the non- transmittive surfaces of the prisms. Focusing in this embodiment is affected by a threaded magnetic ring movable about the objective mounting piece to slidably move a negative lens within that mounting.

As shown, on the wall of the compartment a, Fig. 3, opposite a light-tight door b are mounted a pair of removable rotary film spools f, housed in light-tight containers, film feed and tensioning rollers g, and an exposure gate h. The front wall carries a lens system d in the rear of which may be provided a mounting 5 for a microscope for focusing, or an electric discharge lamp and lens for projecting a lightspot time-scale on to the film. For spool adjustment, rotatable finger pieces i are mounted on the door b, engaging the spool spindles when the door is closed.
