Abstract: 1403842 Treating refuse ARBMAN DEVELOPMENT AB 15 May 1973 [17 May 1972] 23073/73 Headings C1K and C1J Refuse, e.g. garbage and/or sludge, is treated by burning the combustibles present therein, e.g. in furnace 4, washing the combustion gases and neutralizing the impurities therein with lime, e.g. in scrubber 24, to form a calcium sulphate sludge, mixing this sludge with the ash formed and other slag products if any of the combustion to form a raw material which is then sintered (e.g. in furnace 12) to form an insoluble ceramic end product. The combustion gases after the washing and neutralization are returned to the atmosphere as water vapour and CO 2 . The ash particles may be separated off from the combustion gases, e.g. in a cyclone 8, and added to the raw material. A dewatering step prior to combustion may be included. In the examples, after the combustion ash, gypsum sludge, and other slag products if any are shaped, e.g. into balls or cakes or strip like shapes, and sintered and in the case of the last two shapes are subsequently fragmented. Mixtures of ash and gypsum sludge together sometimes with clay or silica sand are described.

Title: Improvements relating to the control of the load factor in electrical current-supplysystems to factory and similar installations including electrical resistance furnaces
IPC: H02J3/18
Filed: 1927-09-03
Abstract: 301,814. Birmingham Electric Furnaces, Ltd., and Lobley, A. G. Sept. 3, 1927. Controlling consuming devices; equalizing load on generator.-In an electrical installation comprising one or more furnaces A, and in addition other plant, the rating of the furnace is reduced when the load on the other plant exceeds a predetermined value. The furnace is normally controlled by a thermostatic relay B<1> operating a contactor B. Heavy load on the other plant causes a relay C<2> to de-energize a contactor C and thereby cut-out one of the heating elements of the furnace. Various modifications are described. In a six-element furnace operating on A.C. the opening of the contactor changes the connection of the element from a double star to a delta with two elements in series in each side. Two contactors, closed alternately may be used to change a three element furnace from delta to star connections on increase of load, or to alter the tapping positions on an auto-transformer in the supply circuit. If two three-element furnaces are used, the contactor operates as for a six-element furnace. If it is inconvenient to make the relav C<2> sensitive to the non-furnace load, it may be operated differentially according to the total load and the furnace load. The relay C<2> may be a power relay instead of a current relay. Time switches may be installed to start the furnace before any non-furnace load would be used, and integrating meters may be used to indicate the total energy supplied to a furnace.

Abstract: 317,634. M³l1er, A. H. Aug. 14, 1928. Elevated railways and tramways.-In a suspension rail track system the trucks are moved along by traction motors and are flexibly connected a predetermined distance apart, the spacing of the trucks being ensured by braking devices which come into action automatically when the tractive effort in the flexible connecting means decreases below a predetermined limit. The truck b, Fig. 4, is suspended from a rail a by a system of bell-crank levers g pivoted at n to the wheel-carrying members h. A draw-bar l connects the bell-crank levers and forms the connecting means, through a flexible member c, to the preceding truck. The truck b is suspended on one side of the pivot n by a hook G and a brake rod B with brake e is connected to the other so that when the truck is at rest the weight applies the brake e to the underside of the rail and when the flexible member c is in tension the brake is released. The brake pressure may be applied by springs which are compressed to release the brakes when tractive effort is applied to the member c. A train of carriages may have an intermediate traction motor d, Fig. 1, which is controlled by the movement of a lever h, Fig. 5. The lever is normally drawn by the spring i into the position 1 and when the lever is drawn into the position 3 by the pull of the member c the traction motor d is set in motion. The front part of the train may have two traction motors. and, if not controlled by a driver, are provided with buffers m which operate to stop the motors upon meeting an obstruction and to start them again when the obstruction is removed.

Title: Methods for the preparation of photoconducting films and devices incorporating such films
IPC: H01L21/00
Filed: 1956-07-30
Abstract: <PICT:0836886/III/1> A method of making a photo - conducting film comprises reacting the vapour of cadmium and a cadmium halide with gaseous hydrogen sulphide or selenide, in the absence of luminescent activator materials in contact with a vitreous base - plate heated to 400-600 DEG  C.  The method may be carried out in the apparatus shown in the Figure.  A glass disc 13 is heated at 400-600 DEG  C. while a mixture of 3 parts by weight of powdered metallic cadmium and 1 part of cadmium chloride, which is gradually introduced into the heated crucible 10 via tube 6, is vaporized and mixed with hydrogen sulphide introduced through tube 4.  The mixture of gas and vapour reacts on contact with the plate to produce a crystalline chlorine-containing cadmium sulphide layer with optimum sensitivity at a wavelength of 530m  but also sensitive to ultra-violet and X-rays.  By using a mixture containing zinc and zinc chloride in addition so that equal amounts of cadmium and zinc are present a layer with maximum sensitivity at 400m  is obtained.  Hydrogen selenide may be used in the above examples instead of hydrogen sulphide to produce a cadmium selenide layer. Specifications 711,015 and 760,587 are referred to.
