Abstract: 1,109,945. Gas vents for electric cells. SONOTONE CORPORATION. 8 Aug., 1966 [12 Aug., 1965], No. 35430/66. Heading H1B. In a sealed rechargeable battery cell which develops gas pressure when charged there is provided in one wall a vent opening which is sealed by an elastically stretched plastic or polymer diaphragm overlying the wall but which is lifted from the vent opening by a predetermined internal gas pressure and so releases excess gas. The arrangement may be used with a sealed cell having a thin sealing membrane which is punctured when the internal gas reaches a certain point. In one embodiment (Fig. 1) the vent is an opening 53 (associated with a pointed projection 54) in a cover wall 51, the vent being closed by a stretched sheet 61 of plastic material. Cover wall 51, sheet 61, a thin metal membrane 36 and a metallic terminal wall 67 are secured to the cell case 23 by a gas-tight insulating seal 57 formed by the collar of an insulating separator 64. When gas pressure in the cell exceeds a certain level diaphragm 36 is outwardly deformed and is punctured by the pointed projection 54. If the gas pressure remains above the predetermined level the sheet 61 is lifted so that excess gas escapes through opening 53, openings 63 in the plastic sheet 61 and openings 69 in the metallic terminal wall 67, the sheet 61 returning to its former position and so closing the vent 53 when the pressure is reduced.

Abstract: <PICT:0619564/IV(a)/1> <PICT:0619564/IV(a)/2> <PICT:0619564/IV(a)/3> <PICT:0619564/IV(a)/4> Filaments, films and the like of cellulose acetate are dried throughout their section by the action of a radio frequency electrostatic field applied as they issue from the spinning orifice through which the solution or suspension of acetylated cellulose is forced, the dried filaments or films being subsequently wound up on a collecting device.  If desired, the member in which the spinning orifice is situated, and the winding device or a guide roller receiving the filaments may form the heating electrodes, thus concentrating the lines of force along the filaments or film instead of transversely thereto and giving the maximum heating effect.  The atmosphere in the spinning cabinet may, if desired, be saturated or supersaturated with acetone or other suitable solvent to prevent initial rapid drying out of the outside surface of the filaments.  In Fig. 1, a spinneret 12 centrally disposed near the upper end of a spinning cabinet 13 is connected to the negative or earth side of a source of radio frequency energy 20.  The positive pole is connected to an insulated guide 18 over which the filaments 17 are drawn, this guide being disposed beneath a central aperture 16 in the lower end of the cabinet.  To prevent rapid initial drying an atmosphere saturated or supersaturated with acetone or other suitable solvent is injected through a nozzle 33 mounted in the wall of the cabinet.  The base of the cabinet carries a drainage tube 14 for drawing off condensed solvent.  To prevent the filaments from being wound in a positively charged condition, a further guide 19 is interposed between the guide 18 and the wind-up roll 23, this guide 19 being connected to the negative side of the source of energy, thus earthing the filaments.  Alternatively, the guide 18 may be replaced by a guide 24 (Fig. 2) midway along the cabinet, and the guide 19 by a guide 25 beneath the outlet aperture 16. Fig. 3 shows a modification using spaced heating electrodes 26 and 27; in this case the electrostatic field lies transversely to the filaments 17.  A cavity resonator 29 (Fig. 4) may also be employed, the filaments passing therethrough and being heated by micro-waves passing along a wave-guide 30 into the resonator.
