Title: Improvements in heat-sealable label stocks
IPC: C09J7/21
Filed: 1953-03-31
Abstract: 733,387. Heat-sealable labels. LEISTIKOW, F. W. R. (McLaurin-Jones Co.). March 31, 1953, No. 8899/53. Class 140. Heat-sealable wrappers, labels, tapes, or the like comprise a backing sheet having a normally dry non-tacky coating of heat-activatable adhesive on one surface thereof which comprises two separate and distinct superposed and mutually adherent layers, one containing a thermoplastic heat-sealable resinous material and the other containing plasticizer for the material, both the material and plasticizer being solid at normal temperatures which layers are adapted to blend on heating to cause the plasticizer to merge with the resinous material to render the coating tacky and adhesive, the coating retaining its adhesiveness for a substantial period after cooling, and finally returning to a hard non-tacky condition. The coating should be non-tacky at at least 120 F. and fuses below 200 F. In examples. (1) the base sheet is first coated with a composition of a styrene polymer, glycerine mono-ethylene glycol ester of hydrogenated rosin as tackifier, aryl alkyl polyether alcohol dispersing agent, styrene-butadiene copolymer aqueous dispersion as adhesive bonding agent to bond the layer and the top coat together, and toluol. After this base coat has dried, a top coat of the same dispersing agent, adhesive bonding agent, sodium polyacrylate solution thickening-agent, disphenyl phthalate plasticizer, and water is applied and again dried. In example (2) a chlorinated hydrocarbon is used in place of diphenyl phthalate in the top coat. In examples (4), (5), (6), (8), (9) the same top coat as (1) is used on base coats of (4) polyamide resin, produced by the reaction of dimerized and trimerized linoleic and linolenic acids of soya bean oil with ethylene diamine, cellulose nitrate, toluol, methyl alcohol, acetone, adhesive bonding agent, and " Santicizer " (Registered Trade Mark) plasticizer; (5), (6) nitrocellulose heat sealing lacquer; (8) composition of (1) with a wax emulsion anti-blocking agent; and (9) as in (1). In example (3) a base coat of " Vuecote," cellulose nitrate, " Santicizer " (Registered Trade Mark) plasticizer, adhesive bonding agent and acetone, is overcoated with a composition as in (1). In example (7) a base coat similar to (1) has a top coat of menthyl phenol plasticizer, adhesive bonding agent, and dispersing agent. Example (10) has a base coat of microcrystalline wax, polyisobutylene, polybutene and isobutylene-styrene copolymer with top coat of (1). The thermoplastic resinous material which may also be cellulose acetate or ethyl cellulose may be in the base coat and the plasticizer in the top coat as exemplified or vice versa. An additional barrier layer of a thermoplastic material chemically inert at normal temperatures with respect to the layers but miscible with them when they fuse, e.g. a wax film, may be included between the layers. Backing sheet referred to is paper. Specification 665,196 is referred to.

Abstract: 926,512. Substation equipment. R. J. H. CLIN, and R. C. E. CHARLET. March 8, 1962 [March 8, 1961], No. 8998/62. Class 40 (4). A relay RT which when energized disconnects the telephone apparatus from the line is released for a prescribed period after the receipt of an incoming call, so that a second call during that period is directed to the telephone apparatus. A subscriber wishing to receive only urgent calls sets a button B to its upper position to energize relay RT, the line being connected to answering equipment 10. On an incoming call, relay RA responds to ringing current and bridges relay RL across the line to trip the ringing, and this relay energizes signalling apparatus V which delivers a characteristic tone or a recorded oral or other message to the caller. The apparatus V is disconnected by a timer MV after 20 seconds, say, and a few seconds later a timer MC disconnects relay RT for a period of 10 seconds, say, when its circuit is remade by a timer MD. An incoming call during that period is thus received at the telephone apparatus 20, and the subscriber must restore the button B to its lower position to maintain the connection. The signalling apparatus V is not essential and may be omitted.

Filed: 1917-06-26
Abstract: 115,943. Cox, H. W., and Cowell, J. H. June 26, 1917. Switches, quick-action.-In step-bystep snap-action switches actuated by a turn-knob connected to the switchblade carrier D through a spring H, which is strained while the blade carrier is held, the holding-means consists of a detent F mounted on an eccentric B fast on the turn-knob spindle A, and having, in addition to the detent face F<2>, a projection F<3>, the face and projection engaging the fixed stops C<1>. The blade-carrier has a crank-pin E movable in a slot F<1> in the detent. When the spindle is turned, the detent is moved inwards by the eccentric until the face F<2> leaves the stop C' the crank-pin is then at the outer end of the slot, and positive disengagement of the switch blades from the fixed contacts is ensured. The spindle has to be turned for each switch movement a greater angular distance than exists between successive stops C', so that after the blade-carrier has moved, the spindle retracts slightly, and the eccentric forces the projection F<3> against the stop and prevents return movement of the blade-carrier. Reverse movement of the spindle A with respect to the blade-carrier is prevented by the crank-pin entering a notch B<1> in the eccentric.
