Title: Battery Separator and process for making same
IPC: H01M50/491
Filed: 1966-10-03
Abstract: 1,158,705. Reinforcing edges of and seaming non-metallic sheet material; moulding battery separators. MONSANTO CO. 3 Oct., 1966 [22 Oct., 1965], No. 44094/66. Headings B5A and B5K. [Also in Divisions D1 and H1] A battery separator 10 comprises a plurality of acrylic fibres containing at least 80% acrylonitrile and of diameter less than 20Á arranged in a randomly overlapped relationship and densified by heat and pressure into a microporous fibrous felt 12 having an average pore size of less than 60 Á. The fibres can have an average diameter of 3 Á. The separator can be made by hot pressing or calendering a web of density 33À8-169À0 g./sq.m., e.g. at 93À33- 204À44 C. at 352-35200 g./cm.<SP>2</SP> for 5-60 seconds between caul plates coated with P.T.F.E. Before pressing the web can be impregnated with a resin, e.g. a cross-linked acrylic, polyvinyl chloride or an aqueous solution of a water-soluble phenolic resin. Alternatively the fibres may be bonded directly fibreto-fibre by virtue of the presence of solvent from the spinning process causing them to become thermoplastic during pressing. The web may be self-supporting or it can be secured at its outer periphery to a frame 14 of thermoplastic acidresistant material, e.g. polystyrene, butadienestyrene copolymer, polyacrylates, such as polymethylmethacrylate, and a polyvinyl chloride sheet 0À508 cm. thick. This sheet can be formed with raised ribs 16 by moulding at 21À1-42À2 kg./cm.<SP>2</SP> at 93À33-204À440 C. for 5-60 seconds and cooling under a pressure of 21À1-42À2 kg./cm.<SP>2</SP>. The laminating of the frame 14 to the web can be performed under the same conditions as the moulding above. The web can be planar or it can be pressed into the raised ribs, see Figs. 2 and 3, not shown.

Filed: 1969-09-19
Abstract: 1279829 Television NIPPON COLUMBIA KK 19 Sept 1969 [26 Sept 1968] 46366/69 Heading H4F  In colour television cameras wherein a single pick up tube in conjunction with a striped filter produces e.g. red and blue signals, on subcarriers of differing frequency, and a luminance signal not on a subcarrier, the response of the colour signals falls off at the edges of the tube due to a loss in resolution and a consequent reduction in subcarrier amplitude, and the colour balance at the picture edge is incorrect i.e. when the green signal is derived from the red, blue and luminance signals. In the present arrangement, voltage waveform generators control the gains of amplifiers inserted in one or more of the separated colour channels in a cyclic manner at line and frame frequency to counteract the variable response. Fig. 3 (not shown) illustrates a suitable circuit for such an amplifier when placed before an envelope detector, although it is also possible to incorporate such an amplifier after the detector. Colour signals may also be generated by scanning a monochrome photograph recorded by a camera using a suitable striped colour filter.

The liquid or gaseous fuel supply to a modulating burner 3 of a space heating system, is controlled by adjustment member 14 in response to adjustable room thermostat 19, or a thermally actuated draught sensor 20 located in a measuring tube 25 extending between the burner inlet zone 1a and a combustion gas flue 4, which ever is tending to restrict the fuel supply the most. Variations in either of these quantities are transmitted to the member 14 through liquid filled capillary tubes 17, 18; an increase in the room temperature tending to decrease the fuel supply, whilst an increase in the draught available tends to increase it. The variation in position of fuel adjustment member 14 is itself transmitted through mechanical linkage 31 to draught regulator 6 to so vary its angular setting through adjusting pin 29 that it is more sensitive to variations in draught at low fuel supply rates and less sensitive to such draught variations at higher fuel supply rates.
