Title: Process and apparatus for charging accumulators
IPC: H02J7/00
Filed: 1968-08-14
Abstract: 1,203,847. Charging batteries. ACCUMULATORENFABRIK SONNENSCHEIN G.m.b.H. 14 Aug., 1968 [14 Aug., 1967], No. 38779/68. Heading H2H. The charging of an accumulator is regulated by electronic means controlled by a voltage sensor, a temperature sensor and a gassing-rate sensor; and decrease of charging current below a predetermined lower limit causes cut-off or reduction to a trickle charge. Additional control by a heat production sensor may also be provided. Battery 47 is charged via transistors 55, 53 and 57, the transistor 55 being controlled by a gas pressure-responsive device 40, the transistor 53 by a temperature sensor 41, and the transistor 57 by zener diode 48. A currentresponsive signal derived from resistors 44 and 50 (the latter having a negative temperature coefficient) is also fed to transistor 57 via a transistor 45 and serves to cut off transistor 57 when the charging current falls below a predetermined value. A resistor 58 may be connected across transistor 57 to provide a trickle charge when the latter is cut off. Three embodiments of a gas-pressure responsive device, which allows escape of gas above a predetermined pressure, are diagrammatically disclosed (Figs. 1, 2 and 3, not shown). A heat production sensor (not shown) may comprise an arrangement of two temperature-responsive sensors such as 41, one being in heat contact with the battery and one subject to ambient atmosphere, -or a thermocouple may be used with one junction in thermal contact with the accumulator and the other in the surrounding atmosphere.

A top roll carrier and weighting arm is retained, when the machine is stopped and it is unlocked from its operative position, in such a position that thread twist cannot spread into the drafting field. In Fig. 1 the arm 1 is retained in its operative position by a toggle arrangement 4 which when unlocked allows the arm to rise to the position shown by the dash-dot lines. The arm is acted upon, through surfaces 11 at its rear end, by resilient members 8 fixed either side of the arm mounting bracket 2. The bearing surfaces 11 are so designed that the top rollers are forced downwardly with a moment which decreases as the distance between the carrierarm and the bottom rollers is increased. The resilient members may alternatively take the form of spring bars, leaf-springs, coil-springs or spring rods, and an intermediate member may be inserted between the spring and the bearing surface on the arm.

Abstract: 856,259. Fired aggregate. STRUCTURAL CONCRETE COMPONENTS Ltd. Dec. 3, 1958 [Dec. 17, 1957], No. 39230/57. Class 22. [Also in Groups XII and XIII] Fired aggregate such as clay or shale for use in concrete is produced by feeding pellets of the raw material into a preheater and drier 3 through which they flow by gravity along a series of inclined partitions 4 arranged in a vertical zig zag formation, while an oscillating pivoted flap valve 8 intermittently retards the flow of pellets to supply a uniform feed to a rotary furnace 12 and a blower 47 draws hot gases from the furnace through the pellets in the preheater 3, the fired pellets being cooled in a cooler 27. The partitions 4 are inclined at an angle slightly more than the angle of repose of the pellets and the flow control valve is actuated by a driven rotary cam, the speed of which regulates the flow of pellets. The dried pellets leave the preheater at about 1000‹F., are fired in the furnace 12 at a maximum temperature of 1850‹F. and are discharged from cooler 27 at about 250‹F. The air cooling in cooler 27 is effected by blower 33 and the discharged hot air is circulated to the burner 43 at the outlet end of the furnace, and via pipe 49 to the inlet end of the furnace and also via pipe 48 to headers 54, 55 and 56 for distribution in the preheater 3. The cooler 27 is of similar construction to the preheater 3 and the discharge rate is controlled by a second oscillatory valve.

A cathode-ray tube for a projection television or radar receiver or oscilloscope includes a concave mirror 14, apertured to allow passage of electrons from a gun 68 to a phosphor screen 12, and arranged to reflect light from the screen through a transparent faceplate 18. The screen and mirror are mounted in a common support 28, which is mounted relative to fixed locating means, e.g. faceplate 18, by an axial pin-and-socket connection, with resilient means to urge the pin into the socket, to allow relative axial movement due to expansion while preventing relative transverse movement. As shown, mirror 14 is of glass with an aluminised reflective surface and a conductive coating over its remaining surfaces, and is held against ledge 26 in metal cylinder 28 by a helical spring 30. The phosphor screen 12 is formed on a stainless steel backing secured to cylinder 28 by spider arms 36, cylinder 28 being blackened and/or provided with fins for good heat dissipation. If a magnetic deflection system is used cylinder 28 has thin walls and a longitudinal gap to prevent losses due to eddy currents, or electrostatic deflection plates may be used, leads therefor passing through apertures in cylinder 28. A locating pin 46, arranged to slide in an aperture in faceplate 18, is secured to cylinder 28 by spider arms 48 and a ring formed with projections or an annular kink 48a urged into contact with faceplate 18 by four springs 52 bearing against shoulder 54 of the envelope. The faceplate 18 may be attached to the glass envelope by a fillet 40 of solder glass or may be integral therewith. An insulating holder 64 is cemented to faceplate 18 and supports an optical diaphragm stop 20 and a meniscus 22, or a Schmidt corrector plate. The meniscus 22 may alternatively be arranged inside the envelope. The holder 64 may be extended towards the electron gun to support magnetic deflection coils. Three tubes having screens which provide images of different colours may he so arranged that the projected component colour images are superimposed on a common viewing screen, Fig. 7 (not shown). The viewing screen may be of an image intensifying type.

Title: Process for the manufacture of artificial filamentary materials of viscose
IPC: D01F2/10
Filed: 1960-11-16
Abstract: In the spinning of viscose filamentary materials, there is added to the viscose at any stage in its production, and/or to the acid spinning bath, a modifier consisting of an N-(phenyl) thio-semicarbazide of the general formula:-  <FORM:0904481/IV(a)/1> in which R represents -H, -CH3, -C3H5, -OCH3 or -OC2H5, and the viscose is spun in a spinning bath containing at least 5% of a zinc salt.  Preferably, 0,05% to 0,5% by weight of the modifier is added, calculated on the weight of the viscose or the spinning bath as appropriate. In an example, cellulose is steeped for one hour at 19 DEG -20 DEG C. in 19% caustic soda, reduced to fibres, and the disintegrated alkali cellulose pre-ripened for 16 hours at 18 DEG C., and then xanthated at 28 DEG -30 DEG C. for three hours.  The xanthated alkali cellulose is dissolved in caustic soda and 0,3% by weight, calculated on the viscose, of the modifier N-(phenyl) thiosemicarbazide added.  The viscose is then after-ripened at 130 DEG C., and filtered, its composition being 6,5% cellulose, 6,2% caustic soda, 40,0% carbon disulphide, and 0,3% modifier, its viscosity 91 and salt point 9,0.  It is then spun into a bath containing 80 g./l. sulphuric acid, 135 g./l. sodium sulphate (anhydrous), 95 g./l. p  zinc sulphate (anhydrous), maintained at 55 DEG C., and the freshly spun tow stretched 98% in a bath containing 55 g./l. sulphuric acid, maintained at 90 DEG C.  Filaments so made have an all-skin structure and a rounded cross-section, and show enhanced elongation and swelling properties.
