Abstract: 961,108. Ink-ribbons. W. H. WOLOWITZ. Feb. 7, 1963 [Feb. 8, 1962 (2)], No. 5044/63. Heading B6F. A composite typewriter ink ribbon comprises two strips 18, 20, Fig. 2, secured adhesively in a side by side relationship along their longitudinal edges to an ink-impervious synthetic plastic support strip 24, having an adhesive applied to one surface area 26, whereby the strip 18, which is saturated with ink is only attached to the support strip along its longitudinal edges. The strip 20 may be a camouflage or correction strip made of paper and carrying a transfer coating 22. The strip 20 may also be an inking strip of different colour. To prevent contamination of the ink by the adhesive the inking strip is protected by an ink-impervious layer 27 of synthetic plastic material. In another embodiment (in Fig. 3, not shown) the impervious protective layer may be heat sealed to the inking strip along the outer longitudinal edges. In a further embodiment (Fig. 4, not shown), the, inking strip may be doubled over along its longitudinal medium and then heat-sealed to the protective layer to provide an increased ink supply. The inking strips may be of natural or synthetic woven fibres, fusible fibres being selected where heatsealing of the protective layer is preferred. The longitudinal heat seal also provides an interstrip barrier against migration of saturants from one strip to the other. The method of making the composite ink-ribbons comprises making a pair of ribbons each including a synthetic support 112, 112<SP>1</SP>, Fig. 7, and overlying fabric portions 110, 110<SP>1</SP> superposing said ribbons in face-to-face contact, simultaneously severing the superposed ribbons into two longitudinally extending partial-width ribbons R and B, Fig. 9, and heat-sealing together the margins of the common severed edges. The partial-width ribbons are then flattened out, Fig. 10, to provide a pair of full-width ribbons having a fused ink barrier 128, 130, extending along the medium line, connecting said strips but isolating them against saturant migration. Saturation of the strips with the respective coloured inks may be effected prior to or after superimposing and separating. In another embodiment one of the strips comprises a paper or synthetic plastic support 132, Fig. 11, having a coating 134 of a transferable material such as an error-obliterating or camouflage material and the protective film 112 edge-welded thereto and a second inked or inkable strip 110<SP>1</SP> having a similar protective film layer 112<SP>1</SP>. In a further embodiment (in Fig. 13, not shown) only a narrow, medium strip 112 is applied to the support 132. In a still further embodiment (Fig. 14, not shown), the other strip of the composite ribbon comprises a synthetic plastic base carrying a waxy colour deposit.

Title: Improvements in or relating to valves or cocks
IPC: F16K5/06
Filed: 1946-02-20
Abstract: 612,328. Rotary valves. MILES AIRCRAFT, Ltd., and HAYDEN, P. T. Feb. 20, 1946, No. 5288. [Class 135] A valve comprising a rotary cock 2, Fig. 1, with a through passage 2a alignable in the open position with a tubular seat member 12, and in which the latter can be withdrawn axially away from the cock to allow the cock to be rotated, after which the member 12 moves back again into sealing contact with the cock, is characterised in that the cock and the member 12 are actuated by separate motors incorporated in the valve. Normally, the member 12 is urged by a spring 16 against the cock, but when a coil 14 is energized, member 12 is pulled away from the cock to allow the latter to be rotated. When the valve has operated and current through coil 14 is cut off-which may be effected by means of switches operated by one of the movable members-member 12 will again be forced against the valve. The latter carries a rubber seal 2c, rotates on balls 2b, 3a, and is actuated by solenoids 20, 20a. The valve spindle is surrounded by a sleeve 4 which can slide up and down the spindle but is prevented from rotating relatively thereto by balls 10 which engage in recesses in the spindle and in longitudinal grooves in the sleeve. A fixed stud 8 engages in a helical groove in the sleeve so that longitudinal movements imparted to the sleeve by energizing the solenoids also cause the sleeve and spindle to be rotated. An abutment 11a carried by the valve engages fixed stops. 11 to limit the amount of rotation of the valve. The valve also carries a piece of soft iron which lies opposite a recess in the casing when the valve is in one of its limiting positions. The presence of the soft iron causes the pivoted pole pieces of a magnet housed in the recess to be pulled over and to make an electrical circuit giving an audible or visible warning. In a modification, the warning switch comprises a fixed contact 34, Fig. 4, and a movable contact 33 carried on the end of a lever 29 fulcrummed at 28. The outer end of the pin is carried by a sealing bellows 30 and the lever is rocked and the switch is " made " when a projection 37, carried by the rotary valve strikes a 3pring 38 carried by the end plate of the bellows and deflects the latter.
