Abstract: 362,982. Cabinets. WILSON, E. L., 16, Maldon Road, Wellington, Surrey. Sept. 12, 1930, No. 27300. [Class 52 (i).] Sliding shelves and the like for cupboards, ovens and the like are operated by the opening and closing of the door, which is connected through a lostmotion device to a lazytong system pivotally connected to the cupboard &c. and to the shelf. In the construction shown, a series of lazytong links 6 is pivoted at the rear to a bracket 9 on the rear wall of an oven, and at the front to clips 6 secured to the rear of the sliding oven grid 13. To the rearmost links 8 are secured arms 20, pivotally connected to links 21, the other ends of which are pivoted to a T-member 22 adjustably secured on a rod 23. To the front end of the rod 23 are pivoted links 24, 25, the other ends of which are pivoted in lugs 26, 27 secured respectively to the side of the oven and to the inside of the door 18, the hinges of which are shown at 19. The linkwork is such that movement of the door through a right-angle from the closed position produces no movement of the arms 20, but movement beyond this position causes the arms 20 to expand and retract the lazy tongs 6 to operate the grid 13. To enable the mechanism to be adjusted vertically, vertical rods or the like may be arranged on the back, side, and door of the oven, on which the lugs carrying the pivotal connections may be adjusted.

Title: Method and system for forming coloured marks
IPC: B41M5/165
Filed: 1972-06-13
Abstract: 1350032 Record sheets NATIONAL CASH REGISTER CO 13 June 1972 [22 June 1971] 27489/72 Heading D2B [Also in Division B6] A method of forming coloured marks on a record sheet carrying microcapsules having walls of hydrophilic polymer material and each containing a water-immiscible liquid and at least one colourless chromogenic material comprises applying thereto a water-miseible solvent containing an electron-acceptor material of the Lewis acid type such that the applied solvent diffuses through the walls of the capsules replacing part of the capsule contents thereby causing reaction to occur between the chromogenic and electron-acceptor materials to form a coloured mark without capsule rupture. In the alternative, the electronacceptor material may not be contained in the water-miscible solvent, but may be on the record sheet isolated from the chromogenic material. The solvent may be applied by dipping, brushing, wiping or spraying. A felt-tip marker or aerosol sprayer may be used for applying the solvent. The base of the record sheet may be made of paper or an organic polymeric film. The chromogenic material may be Crystal Violet Lactone, benzoyl leuco methylene blue, a fluoran derivative, 3, 3-bis (1-ethyl-2-methyl-indol-3-yl) phthalide (or the corresponding 1-benzyl derivative) or 9-diethylaminospiro [1, 2-4-benzo-(a)]xanthene-1, 2, 1'- phthalide]. The electron-acceptor material may be a phenolic polymer, phenol-acetylene polymer, maleic acid-rosin resin, partially or wholly hydrolysed styrene-maleic anhydride copolymer or ethylene-maleic anhydride copolymer, carboxy polymethylene, wholly or partially hydrolysed vinyl methyl ether-maleic anhydride copolymer, kaolin, attapulgite, bentonite, silica gel, or a zeolite. According to one embodiment, the capsules and electron-acceptor material may be coated on a record sheet so as to form a colourless design, this being subsequently developed by application of the water-miscible solvent. Alternatively, capsules containing different chromogenic materials may be applied to the base sheet such that application of solvent produces blocks of different colour.

Abstract: 175,331. Selas-Turner Co., Ltd., and Turner, E. Oct. 4, 1920. Gas heating-stoves.-In gas stoves for lighting and heating of the kind comprising one or more burners provided with an incandescent body or mantle within a light-transmitting and radiating surface of fused silica or similar material in juxtaposition to it, provision is made for heating air which is passed into the room. A number of forms of stove are described, Figs. 1 and 2 showing one comprising burners b with mantles c surrounded by fused silica chimneys d and arranged in front of a metal reflector e. Air passes up a passage h, through tubes f surrounded by the waste gases, and thence through a cowl-like top i into the room. Similar forms, having modified arrangements of air-heating passages, and in one case a series of tubes arranged above the chimneys d which lead the gases to the top of the stove and can be swung clear for lighting purposes, are described. In a modification the chimneys d are replaced by a silica panel in the front of the stove enclosing all the burners. Fig. 7 shows a stove in which a number of burners b with mantles c are arranged in a circle in a .cylindrical casing s of silica, air being heated in a central passage p with a cowl q discharging into the room. In similar forms the silica surround is in the form of a bell or cone with an opening at the top, and the central air-heating passage is replaced by an air-heating fitting arranged at the top of the stove and of a similar type to that shown in Fig. 13. In a modification, the burners are surrounded by separate chimneys in place of the single surround, and a vertical tube above each chimney leads the gases to an enclosed top connected to an exit pipe. The stove shown in Fig. 13 comprises a single burner b, mantle c, and silica chimney d, one side of which may be opalescent to form a reflector. The air-heating fitting is formed by a central tube z surrounded by an inverted cone z<1> in which the air is heated. The burner and air-heating fitting may be separately adjustable on the upright 2 so that the air-heating fitting may surround the chimney d to obscure the light. A similar stove having an inverted burner is described.

[Also in Division G3] A programme controlled lathe comprises a saddle 4 which is longitudinally movable by a feed screw 15 relative to an headstock 2. The saddle 4 supports a slide-rest 6, carrying a tool 9, which is movable in an inclined direction, preferably 45 degrees, under the control of a feeler 10, engaging a transverse guide 21 mounted on an auxiliary copy slide 20 which is free to move on a rod 22 and engageable with a rod 18, fixed to a bed 1 of the lathe, or a rod 19, fixed to the saddle, by selective and alternating application of brakes 24, 25 by a double-acting electromagnet 23. The position of the saddle 4 is determined by a screw arrangement 12, 13, which is maintained in positive engagement with the saddle by a motor 11, driving a gear train or rotary arm in a comparator 1-7 so as to operate a microswitch when the equivalent of a programmed movement, from a punched card or magnetic tape recorder, not shown, is reached. When the slide 20 is braked to rod 19 a cylindrical section such as XI is machined and at the end of the movement the electromagnet 23 operates to release brake 25 and engage brake 24 to hold the slide 20 stationary with respect to the lathebed. The feeler 10 causes the slide 6 to be moved outward along direction 7 and with continued movement of the saddle 4 the tool 9 moves transversely to the axis of the lathe. At a further programmed movement, representative of the transverse movement to produce a shoulder, the brakes 24, 25 are alternated to produce the cylindrical section X 2 . It is stated that a curved profile can be approximated by selecting suitably short alternate movements.
