Abstract: 1,247,707. Microporous coating. BRITISH UNITED SHOE MACHINERY CO. Ltd. 13 Nov., 1968 [14 Nov., 1967], No. 53819/68. Heading B2E. [Also in Division C3] Porous bases such as woven or non-woven fibrous sheet material, paper or felt may be coated with a microporous polyurethane sheet material, made by the reaction of a mixture of reactive components at least one of which is polymeric and is normally solid or pasty at room temperature but can be liquefied by heating to an elevated temperature, is prepared by (a) forming an emulsion by mixing the reactive components at a temperature at which the solid or pasty component present is liquefied to provide a continuous phase, the disperse phase being provided by a liquid immiscible, or substantially immiscible, with the reactive components and having a b.h. above the temperatures reached during mixing and reaction, (b) forming a layer of the emulsion and (c) after the reactive components have reacted sufficiently for the continuous phase to become stable against collapse, removing the liquid to leave micropores in the sheet material. The emulsion is suitably prepared by (i) forming a mixture of all the reaction components and thereafter dispersing the disperse phase liquid in the heated mixture, or (ii) dispersing the disperse phase liquid in one of the components which is solid or pasty at room temperature, heating to bring this component to a fluid state and thereafter adding the remainder of the component or (iii) as in (ii) but by dispersing the disperse phase liquid in a mixture of components at least one of which is solid or pasty at room temperature. The pasty or solid reaction component is suitably a polymeric polyol e.g. a polyether or a polyester or a polyurethane prepolymer and the reactive material may be a "one-shot" mixture or a prepolymer system accordingly. Preferably the emulsion is free from solvent for the reactive components or the reaction product. The liquid forming the disperse phase is suitably an aliphatic hydrocarbon and should have a b.p. of at least 100‹C but not greater than 450‹C. Emulsifying agents may be used to aid the dispersion of the liquid in the continuous phase. The emulsion may be applied to surfaces such as casting surfaces e.g. glass or release paper or to porous bases e.g. woven or non-woven fibrous sheet material, paper and felt. If the surface preferentially absorbs one of the components of the emulsion it may be preliminary coated with a discontinuous coating of a natural or synthetic rubber or resin or may be prewetted with that component. The surface is usually heated to evaporate the disperse phase liquid and cure the polyurethane and the coating optionally removed from the surface.

Abstract: 1452946 Typewriters LITTON BUSINESS SYSTEMS Inc 12 Dec 1973 [16 Feb 1973] 57619/73 Heading B6F An electric typewriter, whose platen carriage is movable under the modes letter spacing, tabulating, carriage return and back spacing, has a tabulator blade, which when set and latched will be automatically moved out of and back into its set and latched position by any accidental carriage return or back spacing carriage movement occurring at the same time. Platen carriage (see Fig. 1).-The carriage 79 has a margin rack 94, tab rack 97 and escapement rack 96 in a channel defined carriage member 82 and beam 85. Power roll (see Figs. 1, 2).-Power roll 13 includes a cylinder 33 whose bearings 35 permit rotation relative to frame fixed shaft 27 and one of which is connected through torque limiting spring 42, pulley 26 and belts 25, 19 to motor 17. Tabulation (see Fig. 7).-Pressing a tab button permits a cam (139), Fig. 6 (not shown), to engage power roll 13 so that link 151 moves towards arm 177, as viewed in Fig. 7. This pivots arm 158 about pin 157 so that pin 161 disables the escapement mechanism, projection 160 moves centre 92 clear of margin stops 93 and place tab blade 98 in the path of a set stop 97. Sprung latch plate 168 has a finger 167 able to engage beneath edge 166 of the blade 98 when raised. When the blade 98 is engaged by a stop 97 it is pivoted in the direction 165 about pin 157, so releasing the latch plate 168 and letting the blade 98 move downwards. If the blade 98 is raised and latched during a back space or carriage return, the blade is pivoted in the direction 173, the latch plate 168 not being released. Tab stops 97 are set and cleared by lever 174 which moves slides 182, 183 for setting and clearing respectively. Back space mechanism (see Fig. 9).-As shown back space pawl 102 derives its motion from the power roll 13. The pawl is normally positioned as shown and pivots about pin 197 when it operates. However should carriage return occur at the same time as back spacing the rack 96 will cam the pawl 102 out of its path, this being permitted by the shape of opening 202. Clash prevention, Fig. 11 (not shown).- Should the typewriter jam as a result of the simultaneous operation of the functions back space, tabulation, carriage return, rotation of a wheel (208) by the operator causes a friction belt (214) to unwrap spring clutch 17 (Fig. 1) so that motor 14 can regain full speed before the clutch 17 is re-engaged to drive power roll. Carriage return (see Fig. 1).-The return button permits cam 61 to engage power roll 13. Rotation of cam 61 pulls rod 66 leftwards, as viewed causing friction shoe 77 to engage wrap spring 51 and couple pulleys 46, 49 thereby winding drawband 78. Return is terminated by abutment 80 hitting latch 72 so releasing arm 68 which was latched when shoe 77 first engaged spring 51. Stops 59, 81 ensure cam 61 completes only one revolution.
