Title: Improved means for indicating deflation of pneumatic tyres
IPC: B60C23/04
Filed: 1930-04-29
Abstract: 351,155. Pneumatic tyres. McINTOSH, D., 17, Gill Bridge Avenue, Sunderland. April 29, 1930, No. 13090. [Class 144 (i).] Relates to means for indicating the deflation of a pneumatic tyre wherein the wheel on which the tyre is mounted carries a relatively movable abutment normally held against movement by the pressure of air in the tyre, spring means being provided to move the abutment, when the air pressure diminishes, into the path of circular travel containing a normally stationary operating member of a stationary switch, and consists in that the switch comprises two contacts normally separated against the action of spring means by the operating member, which, when engaged by the abutment, allows the contacts to remain closed during subsequent rotation of the wheel to actuate an electric alarm uninterruptedly. An abutment 1, Fig. 1, engages the inner tube, is urged inwardly by a spring and is mounted on a rod 2 carrying at its other end a member engaging a recess 10a in a rod 10 urged to the left by a spring. These parts are mounted on the wheel. The brake drum carries a pivoted member 13 normally positioned in line with the circular path of travel of the rod 10, and thus forming an abutment for a rod 18 urged to the right by a spring. The arrangement is that, on deflation, the member 1 moves inwardly, releasing the member 10 which then, during its rotation, strikes the member 13 to swing this out of line with the rod 18, allowing this rod to move to the right and close the electric circuit of an indicator or alarm, this circuit remaining closed for subsequent rotations of the wheel. In a modification, the rod 2 actuates a lever engaging the member 13 directly or indirectly, in the latter case by, normally, engaging a conical stop on a rod such as 10. In another modification, the rod 2 carries a piston exposed to the pressure of air in the tyre. In another modification, the member 13 is arranged near the wheel rim, and the rod 2 carries a second rod parallel to itself and directed toward the rim. In another modification, Fig. 7, the member 13 normally separates a pair of contacts carried by springs 43. Specification 329,746 [Class 144 (i), Wheels for vehicles], is referred to.

Abstract: 1,038,986. Waste heat steam boilers; thermal regenerators. WAAGNER-BINO A.G. April 3, 1963 [April 3, 1962], No. 13130/63. Headings F4A and F4K. Above each of a plurality of converters 1 or like steel-making furnaces, a hood 2 is provided in which the furnace gases are burnt with a forced flow of combustion air supplied to the hood through ports 3, all the gases then being directed through a common duct 11 from which they divide to flow either directly (Fig. 1, not shown), or through a branch duct 20 to two or more simultaneously operable heat absorbing units 6 and dust extraction units 7 before passing to a chimney 9. The heat absorbing units 6 may comprise steam generating units, but may include a direct contact injection cooler 46 (Fig. 6, not shown). The converters 1 are of the kind employing an oxygen lance 17. The units 6 together comprise a waste heat boiler and each consists of steam generator, superheating and economizer sections 23, 24, 25. The duct 11 is lined with steam or hot water tubes 12 and the steam from all sources is collected in a drum 10. Inoperative units 6 may be isolated from the waste gas stream by slide dampers 28. Other slide dampers 4 enable individual converters to be isolated for discharging, recharging, and repair as necessary. Additional burners 13 are used to boost the heat to the units 6 when the heat supply from the converters is insufficient. Also as described with reference to Fig. 4, the branch duct 20 contains checker brickwork 21 which is normally heated by the furnace waste gases. During periods when no heat is being supplied by the converters, this absorbed heat is given up to air passed through the channel 20 to a burner 13 at the downstream end thereof for maintaining a constant temperature at the inlet to the steam generator sections 6. The air is supplied to the channel 20 either by way of hoods 2 and duct 11 or, if the dampers 4 are closed, through a valve 22. A slag trap 18 is provided immediately downstream of each furnace hood 2. The checker bricks may be made of carbon or graphite.
