Title: Improvements in electric battery separators and process of making same
IPC: H01M2/16
Filed: 1955-03-29
Abstract: <PICT:0770241/IV(a)/1> <PICT:0770241/IV(a)/2> A battery separator comprises a resin bonded cellulosic sheet having adhered thereto reinforcing ribs consisting of resinous material permeated throughout with minute interconnected pores. The ribs may be composed of vinyl resin or cured phenol-formaldehyde resin or polyvinyl chloride or high-styrene, low-butadiene resinous copolymer-the last three named resins having particles in their pores.  The filler particles may be silica gel, diatomaceous earth, pulverized microporous hard rubber scrap, &c.  The Specification gives examples of how to prepare silica gel filler and resin composition for the ribs. Alternatively, the ribs may consist of deposits of a thixotropic mixture of a porous, water-saturated filler and a resinous material.  The thixotropic mixture may comprise a paste of silica gel and water with vinyl resin plasticol or with phenol-formaldehyde resin or with polyvinyl chloride or with a high-stryene, low butadiene resinous copolymer. In Figs. 1, 2 a resin impregnated cellulosic fibrous sheet 1 has attached to it ribs 2 consisting of resinous composition as that described above; alternatively the resinous material may be deposited in the depressions of a corrugated sheet as in Figs. 3, 4 (not shown).  The phenol-formaldehyde resin composition may have the following ingredients: phenolic resin 1000, methyl ethyl ketone 750, water 1000, sodium hydroxide 4.5, casein 90.  These ingredients are formed into an emulsion in the following way: the water, sodium hydroxide and casein are intimately commingled to form a uniform solution.  The resin is dissolved in methyl ethyl ketone and the resin solution is then added to the water solution with stirring to form a uniform mixture.  The bulk of the ketone is then evaporated from the resulting solution by heat, leaving a resin-in-water emulsion of approximately 46 per cent resin solids.  Specifications 540,549, [Group IV], and 532,475, [Group V], are referred to.

Making metal fabrics; corrugating. - In a machine for bending and shaping wire &c. of the type described in Specification 210,565, wherein a pivoted arm folds the wire on a series of former blocks, additional former arms are used to press the wire closely round the formers during bending so as to ensure that stiff wire such as high silicon wire is bent to the shape of the former. The wire-bending arm D is carried by a rotatablymounted spindle C which carries a toothed wheel E engaging a transverse rack F. The rack carries two sets of stops O<1>, O<2>, and Q<1>, Q<2> which respectively release catches P', P<2> from pivoted arms R<1>, R<2>, and raise the arms R<1>, R<2>. The arms R<1>, R<2> are raised alternately and respectively lift spring-returned spindles G<1>, G<2> which carry the former arms K<1>, K<2> and are provided with toothed wheels H<1>, H<2> engaging the rack, The spindles G<1>, G<2> are held in raised position by slotted collars L<1>, L<2> engaging catches M<1>, M<2>. The formers are pressed down on the table B by a spring-pressed plate V. When the arm D has moved from its extreme position on the side of the spindle G<2> into a position midway between the spindles G<2>, G<1>, a slot in the collar L<2> comes into alignment with the catch M<2> and the spindle G<2> drops and continues to turn so that the primary arm K<2> squeezes the wires closely round the former. On further motion of the arm D the stop Q<2> engages the arm R<2> so as to raise the spindle G<2> and the stop O<1> releases the catch P<1> so that the spindle G<1> may drop when a slot in the collar L<1> comes into alignment with its catch M<1>.

Abstract: 774,039. Cartridge-filling apparatus. DU PONT DE NEMOURS & CO., E.I. April 5, 1955, No. 9882/55. Class 9 (1). Apparatus for filling granular explosive into cartridge cases comprises a hopper 2 through which tamping rods 21 extend to press explosive into the cases 13 placed in a rack 3. Each rod ends in a tapered head 22 having grooves 23 in the tapered surface, along which grooves the explosive flows into the case. The rods 21 are adjustably held in a bar 16 which can be reciprocated between guide blocks 4, 5 by means of rods 18 connected to gears 8 meshing with pinions 20 on a drive shaft 7. A pulley 19 on the shaft may be driven by a motor (not shown) which is also used to drive a paddle 10 within the hopper. The pistons 28 of hydraulic or pneumatic cylinders 6, 6 carry a setting bar 25 which engages lugs 24 projecting from the rods 21. By actuating the cylinders 6, 6 the rods 21 are forced downwardly until the heads 22 contact the bottoms of the cases, the pressure of screws 17 being such as to allow the rods to slide in the bar 16. The pressure in the cylinders 6 is then released and the bar 16 reciprocated, so that explosive falling from the hopper around the rods into the cases is tamped by the heads 22, the stroke of the rods being progressively. shortened as the cases fill up. To regulate the depth of powder above the nozzles an adjustable gate 12 is placed across the mouth of the hopper. The tamping rods and heads are preferably of heavy wood, but non-ferrous metals and alloys, mouldable polymers and synthetic resins may also be used. The screws 17 may be replaced by wedges, springs or magnetic grippers.

Abstract: PCT No. PCT/GB91/00570 Sec. 371 Date Aug. 3, 1992 Sec. 102(e) Date Aug. 3, 1992 PCT Filed Apr. 10, 1991 PCT Pub. No. WO91/15910 PCT Pub. Date Oct. 17, 1991.In a data communication system a signal is coded with n-bit codewords, wherein n is an integer. The codewords are converted to a serial bit-stream and scrambled using a PRBS (Pseudo-Random Binary Sequence) from a PRBS generator (4). The PRBS sequence has a length n x m where m is an integer. At a receiver the serial data is descrambled using a corresponding binary sequence from a PRBS generator (5) matched to that in the transmitter. The descrambling data is decoded in a decoder (6) in synchronism with the binary sequence in the generator (5), thereby maintaining word alignment between the transmitter and the receiver.
