Title: Improvements in or relating to battery separators
Inventor: BOOTH FRANK
IPC: H01M50/443
Filed: 1957-08-22
Abstract: 849,331. Coated glass fabrics. OLDHAM & SON Ltd. Aug. 13, 1958 [Aug. 22, 1957 ; Dec. 4, 1957], Nos. 26591/57 and 37836/57. Class 140. [Also in Group XXXVI] Electric battery separator material is prepared by coating a glass fibre base, the fibres of which have been bonded by impregnation with an acid-resistant thermosetting resin and then curing the resin with a spreadable mixture of a thermoplastic in powder form, a thickening- agent and a solvent for the thickening agent, forcing the mixture into the base, heating to evaporate the solvent and sintering together the particles of the powder material to produce a continuous structure of the thermoplastic extending through the interstices between the bonded glass fibres. The coated base may be passed between scrapers to form a sheet of the base having a flat face on one side and a ribbed face on the other side. The thermoplastic may be polyvinyl chloride or acetate and the coated base may be heated to about 190 C. The thickening agent may consist of alginates, e.g. sodium alginate, celluloses, e.g. carboxyalkyl cellulose such as sodium carboxymethyl cellulose, or an acid resistant resin which may be that used to impregnate the base, e.g. phenol-, cresolfurfural-aldehyde. The size of the pores of the separatory material may be substantially reduced to a predetermined extent by applying to a face of the separation material, particles of a finely-divided thermoplastic so as to form a layer of abutting particles on the face and then fusing the particles together at their points of contact so as to form a continuous network of the finely-divided thermoplastic over the face and adhering thereto, said network having interstices which constitute the pores of regulated size. Specifications 742,058 and 843,452 are referred to.

Cash registers with item-printing mechanism.- An adding-machine of standard construction is er.clcsed, except for the setting and operating devices, by a casing adapted to be locked so as to enable the machine to be used for cash registering and recording purposes. Provision may also be made for releasing a drawer, sounding a bell and printing the item on a record-strip and on a voucher strip or inserted bill. In the form shown in Fig. 1, the adding machine is mounted above a drawer 6 and is enclosed by a casing 7 locked in place by a key at 9. The usual strip from a roll 10 is led over the impression roll 11 to a winding-on roll 14 supported by arms 13 pivoted to the rocking frame 4 carrying the impression roll. This roll drives the roll 14 by means of an endless belt 16. In the second construction shown in Fig. 2, an additional roll 36 supplies a voucher strip 35 led out of the casing at 39 through an ink-ribbon guide and support 37. The rocking of the frame 4 also liberates the drawer 6 by oscillation of the catch lever 21. A rod 25 pivoted to the frame at 24 carries a pawl 28 adapted as the frame rocks to trip the hammer of a bell 33. This pawl may be disabled by being thrown over to the dotted position. The support 37 comprises a frame 38, Figs. 3 and 4, adapted to be secured to the back of the adding- machine and provided with a plate 50 fixed to the frame at an angle. On this plate is slidably mounted a spring-controlled plate 53 surmounted by a serrated bar 56. The strip 35 is guided by a rod pivoted in a bracket 48 and passes in front of the lower run of the ink-ribbon 43 which is guided at 45 to turn twice at right angles so that the ribbon spools may be arranged one above the other on the same spindle. After a length of the voucher strip has been torn off, the plate 53 may be depressed to allow the finger and thumb to seize the strip and pull it upward at the next operation. To adapt the machine for printing on inserted slips a receptacle 57, Figs. 6 and 7, may replace the voucher guide 37, the ink-ribbon being guided as before and an aperture 62 being provided to allow the impression to be made on the slip or slips and on the record-strip. In the Specification as open to inspection under Sect. 91 (3) (a) the drawer is freed by the frame 4 through the rocking of two inter-connected levers, the voucher strip supply roll may be of larger size and the drawer be dispensed with to accommodate it. the ribbon support 38 may be of slightly different design and may be replaced by another construction of support now set forth in Specification 287,035, [Class 100 (iv), Typewriters &c.], and two machines may be mounted upon a common drawer. This subject-matter does not appear in the Specification as accepted.
