Title: Improvements in or relating to toasting machines
IPC: A47J37/08
Filed: 1942-06-22
Abstract: 558,193. Toasting-apparatus. CHERRY, H. E. June 22, 1942, No. 8512. [Class 28 (i)] A machine for toasting sliced bread comprises two superimposed narrow communicating chambers, the upper one being a drying chamber having a mouth at the top for the edgewise insertion of the slice and the lower one being a toasting chamber having heating means associated therewith and having a discharge mouth at the bottom for the edgewise discharge of the toasted slice. and timing means for timing the passage of the slice from the drying to the toasting chamber and its discharge from the latter. A slice of bread may be inserted through the top 14 of the casing into each chamber of two rows of drying chambers 15 where the slices rest upon two detent rods 17 each common to a row of chambers. At predetermined intervals controlled by timing mechanism described below, the rods are moved laterally along slots 27 to drop the slices into electrically-heated toasting chambers 18 where they are retained by similar detent rods 20 which have previously liberated toasted slices. The detent rods 17, 20 are actuated by electromagnets 31 whose armatures are connected to crank discs 25, 28 coupled to the detent rods by links 26, 29, the energization of the electromagnets being effected at intervals through an electric contact 55 carried by a friction disc 43. The friction disc is driven by a motor 39 through a friction disc 42, and the speed of the friction disc 43 is varied to adjust the drying and toasting periods, by means of an external knob on a shaft 49 which, on rotation, slides the disc 43 horizontally in relation to the disc 42. Switches are provided for placing out of operation unrequired toasting elements, and a control is provided for varying the temperature of the heaters.

Title: Improvements in and relating to electric discharge devices
IPC: H01J1/26
Filed: 1935-03-19
Abstract: 453,863. Thermionic cathodes. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, and KNIGHT, H. DE B., 108, Eastlands Road, and DAVIES, L. J., 147, Murray Road, both in Rugby. March 19, 1935, No. 8600. [Class 39 (i)] An indirectly-heated cathode for a discharge device, such as a lamp or rectifier, consists of a cylinder of insulating material containing the heater and having a layer of metal deposited upon its outer periphery, the metal layer presenting an irregular surface formed by being grooved or by having a wire washer, gauze or the like wholly or partly embedded in it, so as to provide a surface of increased area to which an electron-emitting material will adhere firmly. In the form shown in Fig. 1 a wire 22 is wound helically about the insulator 21 and is completely covered by the metal layer 23, in which irregularities are thus produced. In a modification, the helix is only partly embedded in the layer. The helix may be replaced by wire rings or a cylinder of gauze, or the wire may be first overwound with another helix, possibly of different material. In the form shown in Fig. 3, the metal layer 43 is provided with helical grooves 44. The grooves may be made by winding a wire or fibre 42 upon the insulator 41, preferably but not necessarily over a thin metal layer. Metal is then deposited on the assembly, and the wire is removed, either mechanically, or by dissolving, or by burning a thread of fibre or cotton. Longitudinal grooves may also be used. Fig. 4 shows a cathode having an insulator 51 upon which is placed a number of washers 52 which are partly embedded in a metal layer 53. The washers may be of perforated metal or gauze or may have gauze welded to their surfaces. They may be held in position during assembly by metal strips, or in a jig, or suitable spacers may be provided, such as depressions in the washers themselves. The separate washers may be replaced by a strip of metal wound helically on edge. Washers 54, 55 of larger size, preferably flanged, may be used to support a heat shield and may be perforated or wheel-shaped, non-circular, and positioned at any point along the cathode. In a modification, longitudinally extending fins are partly embedded in the metal layer, and radiate from the cathode. Perforated end plates may butt against the ends of the metal deposit and be locked in position by the heat shield or by other means. The cathode may co-operate with a single anode in the form of a cylinder concentric with the cathode or at one end perpendicular to the cathode axis. Alternatively, two anodes may be employed, one at each end of the cathode.

Title: Process for refining hydrocarbon oils
IPC: C10G21/12
Filed: 1936-03-23
Abstract: Hydrocarbon oils are refined and freed from aromatic, unsaturated and also sulphur compounds by a batch or countercurrent extraction effected preferably below 80 DEG  C. with a selective solvent, and may be de-waxed with or without the refining step.  Selective solvents used consist of one or more of the following; tribromethane, tetrabromethane, dibromhydrin, tribromhydrin, methylbromacetate, phenylbromacetate, monobromacetic acid, 2.4-dinitrobrombenzene, methylene iodide, antimony tribromide, arsenic tribromide, o -or - p-bromphenol, bromacetylbromide, b -bromethylacetate, b  : g -propylene bromhydrin, b -g -dibrompropyl alcohol, or mixtures of these.  For refining oils, the selective solvent is used alone or in admixture with an auxiliary solvent; for dewaxing a blend is used. The auxiliary solvents are of three kinds: (1) for increasing the solvent power, solvents which dissolve the hydrocarbon oils completely and mix with the selective solvent in any proportion, for example, benzene, toluene, xylene, cyclohexane, and those aliphatic and aromatic halogen derivatives, for example chlorinated ethylene, propylene or benzene, which are completely miscible with the hydrocarbon oils; (2) for decreasing the solvent power, solvents which do not dissolve the hydrocarbon oils at all or do not dissolve them completely and which mix with the selective solvent partially or completely, for example, water, alcohols, and organic acids; and (3) for improving the selectivity, solvents which dissolve the hydrocarbon oils completely and do not mix with the selective solvent in all proportions, for example, propane, butane, &c. or mixtures of these.  The oils may be extracted with the selective solvent alone or blended with one or more auxiliary solvents, and the oil or the undissolved layer after extraction may be dewaxed by dissolving in a blend of a selective solvent and an auxiliary solvent of the classes (1) or (3), and cooling.  The proportions of solvents are such as to maintain a single liquid phase.  If dewaxing follows extraction the same selective solvent is used and re-cycled to the extraction stage. The refined and dewaxed oil is treated with clay and the raw wax is washed with the solvent blend, of the same composition as is used in the dewaxing or of different composition, for producing petrolatum. The solvents are recovered by distillation or by washing with a solvent for the selective solvents.  In examples, a dewaxed distillate or a residual oil is extracted twice or thrice with sym-tetrabromethane, alone or mixed with heptane, and the raffinate is treated with clay. Mineral oils, low temperature or brown coal tar oils, or fractions thereof such as gasoline, kerosene, gas oils, turbine and lubricating oils may be treated.
