Title: Tape handler with anti-hunt control
IPC: G11B15/29
Filed: 1970-06-18
Abstract: 1,272,701. Feeding record tapes. MOHAWK DATA SCIENCES CORP. 18 June, 1970 [1 Oct., 1969], No. 29710/70. Heading G5R. In a bidirectional tape transport, the reel which takes up tape fed in one of the two directions is prevented from rotating in the non- take-up sense by a detent which is disabled in response to the feeding of a predetermined amount of tape in the other of the two directions. As shown, dancer arms 96, 126 respond to variations in tape tension to control the action of brake bands 85, 120 on reel spindles 82, 138 and the application to the take-up spindle 82 of a friction drive 94 driven by the same motor 52 which drives two counter-rotating capstan spindles 58, 150, made selectively operative by means of corresponding pinch rollers (22, 34), Fig. 1 (not shown). A wedging-action detent 204 normally prevents rotation of the take-up spindle 82 in the reverse direction, and hence oscillation of the take-up reel, but is withdrawn by links 208, 104 when the dancer arm 96 is pulled by the tape through a predetermined angle (anticlockwise in Fig. 3). During normal drive a vacuum pump 175 activates two suction members (24, 32, Fig. 1) to provide a friction drag on the tape. For fast rewind the pump 175 is switched off so that pneumatic transducers 200, 180 disable the detent 204 and bring a rewind capstan 194 driven by a motor 192 into engagement with the supply spindle 138.

Title: Treatment of textile or other materials
IPC: C09D5/22
Filed: 1929-10-08
Abstract: Phosphorescent or luminous yarns, filaments, films, or fabrics are produced by fixing phosphorescent or luminous substances in or on the materials while the latter are in a swollen or softened state. The phosphorescent substance may be applied over the whole surface or locally by printing, stencilling &c. The material may be treated with the swelling or softening agent, and subsequently with the phosphorescent substance, or the phosphorescent substance may be applied simultaneously with the softening or swelling agent which may also act as a mercerizing agent. The phosphorescent materials may be applied to artificial yarns, filaments &c. without special treatment to effect their softening by applying such materials to the yarns &c. during manufacture and before they have coagulated. For example, finely divided phosphorescent material may be applied to filaments of cellulose acetate as they issue from a dry-spinning machine and before they are set.  The phosphorescent substances may be applied to the softened materials by dusting or blowing the substances on to the materials or by applying them in the form of aqueous dispersions or pastes either locally or over the whole surface.  In some cases, colouring matter may be applied together with the phosphorescent substances, while the treated material may be protected against severe wear by the subsequent application of a layer of varnish made, for example, of a cellulose derivative applied in a solution having little or no solvent action on the base.  The process is applicable to the treatment of cotton or other cellulosic fibres such as regenerated cellulose; silk; cellulose esters such as cellulose nitrate; organic acid esters of cellulose such as cellulose acetate etc.; cellulose ethers; and condensation products of cellulose and glycols or other polyhydric alcohols. Suitable softening agents for cellulosic materials are zinc chloride, Schweitzer's Reagent, or caustic alkali, while for cellulose esters or ethers there may be employed acetone or other ketone, ethyl alcohol, diacetone alcohol, phenol, cresol, or formic acetic, or butyric acids.  As phosphorescent substances, there may be employed suitably treated zinc, barium, or calcium sulphide, or, if self-luminous effects are required, zinc sulphide containing a small amount of a radio-active substance.
