A solid fuel grate, capable of being converted from a normally burning open fire grate to a slowly burning grate, comprises bars extending across the front of the grate to support the fuel bed and a front panel which can be moved from an open position in which it acts as a trivet to a closed position against the fire bars and the front panel is hollow so that only its inner wall is subject to the direct heat of the fire. The fireplace front has a main frame with upstanding side posts 8, and members 9, 29, 30 forming the top, bottom and sides of an air admission opening closed by a damper D. Outer side cheeks 1 are secured to brackets formed on the side members of the main frame by screws engaging bosses on the inside of the cheeks. A bottom flange 2 on each cheek is secured to the floor of the fireplace. Inner side cheeks 4 are provided with bottom flanges 62 resting on ledges 3 on the side cheeks 1, and secured to the outer cheeks by screws 4<SP>1</SP>. Fuel retaining ridges 5 are formed on the inner cheeks 4 and a flange 41 co-operates with a flange on the side posts 8 to locate the front fire bar unit comprising side bars 21 and flat bars H set at an angle to the horizontal.

Filed: 1940-04-09
Abstract: 538,147. Coated fabrics. MICAFIL, Ltd. April 9, 1940, No. 6410. Convention date, Aug. 12, 1939: [Class 140] [Also in Group XXXVI] In order to enable the di-electric of a wound condenser or lead-in insulator to be stressed fully, i.e. 10 KV per cm without breakdown at the edges of the conductive coatings, the number of intermediate conductive coatings 9 is increased, with consequential lessening of the thickness of the di-electric layers, so that the voltage between adjacent layers is less than a voltage such that, with a corresponding thickness of di-electric, the edges of the coatings being open to the air, noises or increase of losses due to " corona " would be produced. The conductive layers may decrease in area towards the outside, as indicated in Fig. 2 or they may be displaced laterally to have' a coned longitudinal cross-section. A method of making is described in which the conductive coatings are formed by spraying colloidal carbon on to a web of insulator, to form areas, separated by uncoated insulation of a size dependent on the radius of the winding, such that the insulation forms one or more complete turns between the coatings. The coatings are thin, of the order of 1/30 the thickness of the insulation, which itself is of the order of 1 millimeter.

Title: Manufacture of viscose and viscose bodies
IPC: D01F2/08
Filed: 1931-03-02
Abstract: Viscose is prepared from soda or sulphate cellulose which has been subjected to an alkaline improving process before bleaching, p  e.g. the cellulose may be treated with chlorine and then with a cold caustic soda solution of 6-10 per cent strength, bleaching being effected with hypochlorite after removing the alkali.  The wood of the Scotch pine may be used as primary material.  Examples are given of the production of viscose solutions from sulphate-cellulose, with and without ripening of the alkali cellulose.  The solutions are distinguished by high clearness and yield white products which do not require bleaching, the strength being equal to that of silks &c. obtained from sulphite cellulose.

Title: Improvements in or relating to the production of volatile halides of elements
Inventor: LIND ROBERT
IPC: C01G31/04
Filed: 1955-03-05
Abstract: Volatile halides are produced from volatile oxyhalides by passing the latter in the form of vapour together with excess halogen through a porous carbon plug at a temperature greater than the volatilization temperature of either compound.  The porous plug may be obtained by mixing activated wood or nut shell charcoal with an aqueous solution of a binder such as starch or dextrin, shaping the mixture to fit in a silica reaction tube and carbonizing the binder in an inert atmosphere in situ by means of an electrical tubular heater surrounding said tube, which also provides the heat for the reaction. In the examples: (1) a mixture of niobium oxychloride and pentachloride at above 400 DEG  C. is converted to pure niobium pentachloride; (2) vanadium oxytrichloride is converted at above 148 DEG  C. to vanadium tetrachloride; and (3) phosphorus oxychloride is converted at above 162 DEG  C. to phosphorus pentachloride.
