An electrical storage heater having fan forced air circulation has an air control valve motivated by an electrical means controlled by a temperature sensing device situated downstream of the valve which admits diluent cool air into air previously heated by the heater. Heated air may be supplied to a plurality of rooms through a ducting system. The arrangement may be controlled by a time switch 36 which when operative completes a circuit through a manual reset excess temperature cut-out 38 through a bi-metallic temperature sensitive device TS and a valve motivating means TM. A circuit is also completed through a motor cut-out 39, fan motor windings and a manually or time switch shuntable resistor R1-to increase the fan speed when required. The time switch may also incorporate a room air temperature thermostat 37. An alternative or additional method of boosting the thermal output of the heater comprises a pair of normally open contacts 40, a two position switch S2, resistors R2, R3, and a cam 42 driven by manually operable time delay means (not shown) which closes contacts 40 for a selectable period of time e. g. up to 15 mins. The resistors R2, R3 provide different degrees of boost. In another alternative method of providing boost, an additional heater winding (not shown) connected to a supply via a time delay means of a type described above is provided on bi-metallic strip 29. The means TM is coupled to the valve 19 by a simple link (31) see Fig.3 (not shown) which may incorporate a lost motion coupling to avoid overstressing of the bi-metallic strip. The arrangement is designed so that initially, means TM closes the valve 19 but alternatively it may be arranged to be moved to the fully open position. Device TS may be provided with a mechanical or magnetic snap action arrangement to minimise arcing.

Abstract: 832,876. Regenerative horizontal coke ovens. KOPPERS CO. Inc. March 4, 1958 [March 14, 1957], No. 6959/58. Class 51 (2). In a regenerative horizontal coke oven battery constructed of silica brick above a level between the mid-height of the regenerators and the top of the sole flues between the bottom of the regenerators and the concrete mat on which the battery rests, and constructed of interlocked fireclay brick below that level, the concrete mat is extended upwardly at the sides of the battery to form curbs extending to the top of the fireclay brickwork, and the  brickstays are anchored to the top of the concrete curb and tied at the top of the battery to brace the silica brickwork independently of the fireclay brickwork. In a Becker type coke oven, Fig. 1, the base of the battery structure above the concrete mat 20 to the 3 ft. level of the regenerator partition walls is formed of interlocking fireclay brickwork 9, in which is formed the sole  flues 7. Curbs 47 extend upwardly from the concrete mat 20, and the brickstays 48, tied at the top by rods 49 are mounted on top of the curbs 47 level with the top of the fireclay brickwork. Recirculation ducts 28 in the concrete mat 20, and rich gas nozzles 30, Fig. 5, communicate with Venturi ducts 33 formed in the fireclay base, so that the nozzles 30 can be easily aligned with the Venturi duets 33. The lower part of the rich gas risers 19 formed in the silica brickwork is flared, so that whether the fireclay brickwork extends to the mid height of the regenerators, the 3 ft. level or to the top of the sole flues, as in Fig. 5, the parts of the duets 19 can be aligned easily. The lower ends of the backstays 48 are attached to brackets 50 comprising springs 52 engaging the buckstays and a screw bolt 53 for adjustment. Rectangular openings with steel linings in the curb walls 47 connect the sole flues 7 with reversing boxes 18. The fireclay base is formed of bricks having depending tongues 68, Fig. 11, engaging grooves in the next lower course, and the joints are sealed with air-setting mortar. A layer of mortar 71 is spread on top of the fireclay brickwork, and a further layer 72 of graphitic lubricant allows the silica brickwork to slide easily over the fireclay base as it expands. A heat resistant packing material 74 between the fireclay brickwork and concrete curbs 47 avoids any pressure from the fireclay brickwork on the concrete curbs.

Abstract: 675,404. Making radiators. LEHMANN, E. March 21, 1950, No. 6981/50. Class 83 (ii). [Also in Group XIII] The sections of a radiator for heating buildings (see Group XIII) are constructed from pairs of members 1 stamped from 1.2 mm. coldrolled steel strip B to form recesses 22 and 23 for fluid flow and mid-ribs 26 for subsequent spot-welding. Apertures are cut in the strip B so that, when the steel strip is severed by a tool C, semicircular nicks 24 are formed at the ends of the member to facilitate joining to end headers for the supply and outlet of the heating fluid. A pressing-tool, Fig. 15 (not shown), is used to form flanges 25 on the members 1 which are spot- and seam-welded together electrically in pairs, Figs. 16, 17 (not shown). The pairs are then subjected to pressing in a device H, I, Fig. 18, to bend over the edges of the flanges 25 to form small flanges 29 for welding to plates which form air-shafts between the sections. The radiator is completed by brazing by immersion, when the headers are sealed to the radiator sections.

Abstract: 879,986. Fluid-pressure servomotor-control systems. SIGMA INSTRUMENT CO. Ltd. June 4, 1958 [March 5, 1957], No. 7331/57. Class 135. A fluid-pressure relay, intended primarily for use with the workpiece gauging and sorting apparatus described in Specification 879,987, comprises a main valve 2 governing the connection of a pressure fluid inlet 13 to an outlet 12 communicating with a pressure-responsive mechanism, such as a ram of the work-sorting mechanism, the valve being controlled by the pressure in a chamber 24 formed between the valve 2 and an outlet valve 27 actuated by the push-rod 34 of a bellows unit 21 communicating through a pipe connection 39 with a control pressure, e.g. that in the output (26) of the gauging head valve described in Specification 879,985. As shown, chamber 24 communicates with inlet 13 through an orifice 19 in valve 2, the pressure in the chamber serving to hold the valve 2 in its extreme left-hand position against the force of pressure fluid from an inlet 16 acting against the left-hand operating plunger portion of the valve, and also acting with a loading spring 29 to hold ball valve 27 closed. When a critical control pressure is applied to bellows 21, e.g. when the dimension of a workpiece being gauged results ina predetermined setting of the gauging head, rod 34 unseats valve 27 and the exhausting of chamber 24 to atmosphere through ports 38, 22 allows the pressure fluid from inlet 16 to move valve 2 to the right, thus connecting inlet 13 and outlet 12. Upon removal of pressure from bellows 21 valve 27 is reseated and -pressure again builds up in chamber 24, the connecting of inlet 16 to exhaust enabling valve 2 to move to the left to its original position, outlet 12 communicating with an exhaust port 15.
