Title: A new or improved hearth for a fireplace
IPC: F24B1/193
Filed: 1952-07-30
Abstract: 723,589. Fire grates. DIXON, W. B. July 21, 1953 [July 30, 1952], No. 19267/52. Class 126. A fire grate comprises a base having a series of spaced fins upstanding therefrom. As shown the grate presents the general appearance of a grill in which the front end of each bar is a humped upward enlargement. It is to be noted that the grate is foreshortened such that its rear edge 3 is spaced from the fireplace back 4 thus providing an ash space 5. The grate comprises a base plate 6 mounted on legs 7, 8, formed with integral fins 10 shaped as shown and spaced from one another by straight shallow grooves 11. At its rear end each of the ribs is flattened and widened a little as at 16 and the fins are disposed parallel to one another with the exception of the fin at each end which is inclined to fit the tapered shape of the fireplace. At each of these ends the plate 6 is furnished with an upstanding wall 17 the front part 18 of which is offset at an angle, so that, at this part, the wall is approximately at right angles to the fireplace surround. At its front the grate is provided with a cover plate 19 including a flap 20 covering an opening therein. The grate may be of metal, fireclay or other refractory and the plate 19, flap 20, legs 7 and parts 18 may be made as a separate unit from the remainder of the grate. The base plate 6 may be provided along some of the grooves with air inlet holes and the air flow therethrough may be controlled by a sliding plate. In the latter event the front plate 19 may be omitted or a panel comparable to 20, may be provided to allow the access of air to the space beneath the plate 6. A further feature lies in arranging for the opening of the holes in plate 6 to be effected simultaneously with the opening of the access panel by a common, operating mechanism. The access panel may be arranged to slide or pivot upwardly to obturate the openings at the front of the fire. The grate may be formed from a number of separate sections generally of two end sections of triangular form in plan and a plurality of rectangular in outline intermediate sections. In this arrangement the end sections may be replaced by firebricks.

Title: Improvements in or relating to purification of naphthalene
IPC: C07C7/148
Filed: 1957-06-25
Abstract: Crude naphthalene of coal tar origin is purified by passing in the vapour phase in the absence of oxygen at 450-850 DEG  C. over a catalyst comprising an oxide of a Group VIa metal supported on alumina for a time sufficient to convert impurities to lower molecular weight product, the naphthalene remaining unchanged, and recovering naphthalene.  The catalyst may comprise 5 to 25 per cent of chromia, molybdena or tungstic oxide or a mixture of two or all with 95 to 75 per cent alumina such as activated alumina and may also contain about 2 per cent of an alkali metal oxide such as sodium or potassium oxide.  It may be used in fixed or fluidized beds and is regenerated by an oxygen-containing gas such as air or by steam.  If desired it may be treated prior to use in the purification with hydrogen at 450-850 DEG  C.  Contact times in the purification may be 0.01 second to 1 minute.  In order to obtain naphthalene of m.p. 78 DEG  C. the feedstock should have a m.p. of at least 68 DEG  C. and to obtain a m.p. of 79 DEG  C. the feedstock m.p. should be at least 74 DEG  C.  The naphthalene may be recovered from the products by fractionation or by cooling to liquefy the naphthalene and separating gaseous products and then the naphthalene further purified, if desired, by fractionation.
