Abstract: 1,190,981. Paper; non woven fabric. DEXTER CORP. 30 March, 1967 [18 April, 1966; 17 Feb., 1967], No. 14483/67. Headings D1R and D2B. An unshrunk non-woven fibrous structure is formed from a mixture of synthetic, organic, thermoplastic, cold-drawable fibres and a binder which consists of resins, synthetic resins, synthetic rubbers, conventional papermaking fibres or mixtures of conventional paper-making fibres with resins. synthetic resins or synthetic rubbers, and is bonded by a non-heatbonding process. The cold-drawable fibres are undrawn, have a substantially constant order of molecular orientation along individual fibre lengths, and an ultimate elongation of more than 200 per cent. They may be of polymers, such as polyamides, acrylics, polyethylene terephthalate, polyvinylidene chloride, polyethylene and polypropylene, and may be crimped or twisted. The sheet has good tear strength, and when it is torn the torn edges are bridged by the elongation of the previously undrawn fibres. The papermaking fibres may be a conventional cellulosic pulp, or mixtures of cellulosic fibres and drawn, man-made fibres of composition .the same as or different from that of the undrawn fibres, and may be beaten or unbeaten. The other binder, if any, may be applied uniformly or in spots.  In the Examples: (1) kraft woodpulp is beaten and divided into two parts, drawn nylon fibres are added to one and undrawn "nylon fibres to the other, and the two then made into sheets; (2) kraft woodpulp is beaten, drawn and undrawn nylon fibres are added in varying proportions to portions of the pulp, sheets are made and dried and then impregnated with cross-linked polyvinyl alcohol and dried; (3) Example 2 is repeated, but butadiene-acrylonitrile latex is used in place of the polyvinyl alcohol; (4) Example 3 is repeated, but using an acrylic latex; (5) Example 4 is repeated, but using mixtures of drawn and undrawn nylon fibres in various proportions (6) webs are made by air-laying undrawn nylon fibres only and drawn nylon fibres only and bonded with the self-cross-linking acrylic latex of Example 4; (7) furnishes as in Example 1 contain an epichlorohydrin-polyamide wet-strength resin, are formed into sheets, dried and impregnated with the acrylic latex of Example 4; ,(8) kraft pulp is beaten and divided into two .parts, drawn polypropylene fibres are added to one and undrawn polypropylene fibres to the other, handsheets are made from both and treated with toluene solutions of an acrylic ester resin; and (9) Example 8 is repeated with polyester fibres in place of polypropylene. The materials may be used as base sheets for stencils, or for tapes, as interlinings, or as towels, wash cloths, wiping or dust cloths, headrest covers, table cloths, aprons, diapers, or disposable sheets, pillowcases and dressing gowns, as carpet backings, bookbindings, electric insulation, reinforcing layers for plastics film, imitation leather, clothing, aisle runners, tarpaulins, tents, curtains and draperies, upholstery, food wrapping, pipe wrappings, tea or coffee bags.

Abstract: 381,513. Substation equipment. WEBER, O., Rathen-on-Elbe, Germany. May 23, 1932, No. 14554. Convention date, May 23, 1931. [Class 40 (iv).] The number dialled by a subscriber is automatically printed at the substation near one edge of a tape which is wide enough to permit notes to be made regarding the nature of each call. The finger-hold disc 2 carrying the type 3 may be the normal finger-disc of the dial or an additional similar disc coupled to the normal disc either permanently or by the subscriber's finger. A movable finger-stop 5 has operatively associated with it three levers 59, 6, 16, of which the first 59 moves a pivoted member 62 against an adjustable stop 57 causing the slot 65 to engage one of the pins 64 for the purpose of ensuring that the selected type member is definitely positioned relatively to the tape. The lever 6 after first tensioning a spring 10 withdraws a sliding detent 13 from the member 12 which thereupon moves upwards sharply under the action of spring 10 to bring the tape 14 and ink ribbon 15 into engagement with the type. The lever 16 through pivoted members 17, 25, and pawls 18, 26, advances the tape and ink ribbon. These may also be advanced manually by hand-cranks. In coming calls may be recorded manually on another tape mounted on rollers in an attached casing with slotted face. In a modification, Fig. 8, the digits of each dialled number are printed transversely of the type. The type wheel 42 is carried on a sleeve 41 mounted to rotate with the finger-disc 2 but axially slidable on the member 40. After each setting of the dial the sleeve 41 is moved axially by gearing 43 which is advanced one step by a pawl carried by an arm 48 linked to the lever 16, Fig. 1. After each complete number has been printed, manual rotation of the shaft 51 through a small angle causes arm 53 to withdraw the driving and holding pawls from gearing 43 and at the same time a link 55 advances the tape. In a further modification, Fig. 6 (not shown), the tape is advanced during the forward movement of the dial by a forked lever engaging a stud on the edge of the finger disc, the lever during the return movement of the dial causing a pin to mark the tape in order to indicate any unauthorized use of the dial without moving the finger disc stop 5.
