Abstract: 465,597. Controlling combustion. SATCHWELL, L. Oct. 9, 1935, No. 27910. [Class 51 (i.)] In a boiler furnace the supply of primary air or both primary and secondary air for combustion and the supply of air to the chimney to check the draught are controlled automatically in accordance with the temperature of the water in the boiler by control means arranged in a single casing 20 and consisting of a thermally sensitive member 1 comprising a hermetically sealed expansion vessel containing a liquid and surrounded by water circulating in a container 2 connected by pipes 3, 4 with the water space of the boiler. Expansion of liquid in the vessel 1 actuates a rod 5 and damper 6 pivoted to the top of the casing 20 to control the air supplied to the casing from the atmosphere through a port 12 and its passage through ports 7, 10 leading respectively to primary air supply port 9 and secondary air supply pipe 9<a>, and port 13 supplying air to the chimney. The rod 5 passes through a hole in the damper 6 which is held'between a spring 17 and adjustable sleeve 15 attached to the rod 5. In the modification shown in Fig. 2, the damper 6 is subjected to the action' of an additional thermal expansion device 18 located in the path of air coming from the atmosphere.

Abstract: 767,178. Pit props. GERLACH, H. Nov. 6, 1952 [Nov. 19, 1951] No. 27992/52. Class 20(2) The parts 1, 2, Fig. 1, of a telescopic pit prop are clamped together by means of liquid in a chamber 5 on a solid rubber element, pressure in which is produced by a piston 9, and which engages an element. 13 against the part 1 with which it is. carried down by roof pressure and increases the pressure in the chamber. The inner prop part 1 may taper downwardly. The downward movement of the element 13 is limited by an adjustable stop 15. 'The piston 9 is operated by a transverse wedge 7 movement of which is limited by a stop 18. The liquid chamber is surrounded by a flexible protective casing 4. A friction member 6 is opposite the chamber 4 between the prop parts. In Fig. 3 the liquid chamber 5 and the element 13 are annular and the part of the element 13 extending down inside the chamber is provided with slots 13a and a screw 22 limits the movement of the piston 9. A jacket between the element 13 and the chamber 5 prevents the casing 4 entering the slots. When the prop is to be withdrawn the wedge 7 is driven out so that the piston enters a recess in the wedge allowing complete relaxation of the pressure. In a modification, Fig. 6, a part 30 is held frictionally against the lower prop part 2 by pressure in the liquid chamber 5 and a ring 31 fixed to the upper prop part 1 increases the pressure in the chamber. The prop yields until clearance "a" is taken up and the part 30 is carried down also. In Fig. 7 a wedge 34 arranged opposite the chamber 5 is adapted to be tightened by a setting up wedge 36. Specification 767.179 is referred to

Purifiers; purifier waste, revivifying. - In regenerating adsorption media, such as activated carbon or gels, the medium is heated in shaftlike containers or tubular systems and the substances set free are collected in a chamber or chambers situated in the mass of the medium, and are discharged from the regenerating device, before coming into contact with adjacent cooler layers of the medium, through one or more offtakes communicating with the collecting chamber or chambers. In one arrangement, Fig. 1, the receptacle a, which may be used both for adsorption and regeneration, is provided with collecting chambers f<1> - - f<3> arranged at different levels in the adsorption medium b. The gases set free on heating the receptacle a pass from the collecting chambers to a condenser h through conduits g<1> - - g<3>. The removal of the adsorbed substances may be accelerated by means of scavenging agents in the form of inert gases. which are supplied to the regenerating device at different levels. In another arrangement, Fig. 4, the adsorption medium is passed continuously or intermittently from a hopper k through the regenerating device which is surrounded by a heating chamber m. The scavenging agent is introduced through pipes e<1> - - e<3> and distributors c<1> - - c<3>, the gases set free being withdrawn through collecting chambers, which may communicate with separate condensers h<1>, h<2> when fractions corresponding to different boiling points are desired. In another arrangement, Fig. 5, the scavenging agent is recovered and employed in a cycle. The adsorption medium passes from a hopper k through a slide n into the regenerating chamber, which consists mainly of aggregates of tubes arranged in a heated chamber. The substances set free in the lower and hotter part of the tubular system rise to collecting chambers f connected to the condenser h through a conduit g. The scavenging agent is introduced through distributing chambers c<1>, c<2>, and after passing through the condenser h, is returned to the regenerating apparatus by means of a blower 1. The scavenging gas may be generated in an internal-combustion engine o which at the same time drives the fresh air blast required for the combustion of the heating agent and also drives the scavenging circuit. Losses in the scavenging circuit are made up by introducing fresh quantities of explosion gases into the circuit through a washer q.
