Title: Improvements in oil burning apparatus
IPC: F23K5/18
Filed: 1922-06-06
Abstract: 203,387. Bishop, J. A. June 6, 1922. Vaporizing-apparatus; oil supply.- Oil after being preliminarily heated is gasified in a retort surrounded by a casing containing heated aeriform fluid and is then conveyed through a pipe to the burner. In the apparatus shown, the heater 1 for preliminarily heating the oil in relatively small quantities comprises two compartments 1<a>, 1<b> separated by a partition 2 and containing steam coils 12, 12<a>. The oil admitted through a pipe 3 is fed by a pump 25 to a separator 20 fitted with a filter or strainer 26 through which the lighter oils pass. The filtered oil is conveyed by a valve-controlled pipe 30 and a pipe 31 to a retort 40 containing a filling material 44 such as small metal rods, fragments, tubes &c. and arranged in a casing 50 which is connected by a valve-controlled pipe 51 to the steam main 52 of a boiler 60. A drum 41 arranged within the retort 40 is connected by pipes 42, 43 to the steam space in the casing 50. The oil is gasified in the retort 41 and passes through a pipe 61 at the lower end of the retort to the burner 62. At starting steam from an auxiliary boiler 11 supplying steam to the heater 1 is supplied through a pipe 65 to the main 52 and passes through a valve-controlled pipe 54 and the pipe 31 into the retort 40. The steam breaks up the oil in the retort 40 and forces it to the burner in a partly atomized and partly gasified state. When steam is developed in the boiler 60 it is admitted through the pipe 51 to the casing 50 and the steam from the auxiliary boiler is cut off. Filling material 61<a> such as wire, small tubes &c. may be arranged in the pipe 61 in such a position as to be heated by the burner 62 thereby ensuring complete gasification of the fuel. The separator 20, casing 50, heater 1 may be covered with heat insulating material and are provided with sediment &c. removing pipes 27, 63, 10. Carbon may be removed from the retort 40 by blowing steam through the pipes 54. 31. A bye-pass pipe 70 is connected to the fuel supply pipe 21 leading to the separator 20 in order to lead excess oil back to the heater 1.

Title: Improvements in or relating to electic current collecting brush devices
IPC: H02K13/10
Filed: 1923-06-18
Abstract: 200,495. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Wagner, C. F.). July 5, 1922, [Convention date]. Brush-holders; improring current - - collection, a u x i l i - ary means for.- In a rotary converter or other alternating-current dynamo-electric machine, equal division of the current is ensured among a number of brushes bearing on a common collecting-ring, and equal wear of the brushes is thereby obtained, by dividing the brush-holders into a number of groups connected to current leads coming from equally spaced points on a brush-holder stand which has electromagnetic damping means spaced between the groups of brushes. In the form shown, the brush-holder stand 2 supports groups of studs 3 for the holders 4 which all bear on the collecting- ring 5. The studs are connected in parallel by leads 6 to the common main 7. As the leads 6 are of smaller section than the stand 2, there is a tendency for the greater part of the current to flow through the stand to the lowermost lead 6 and so overload the lowermost brushes. This is prevented by dampers 8 placed at intervals between the groups of studs. The dampers may consist of magnetizable laminae 9 embracing the stand 2 and supported by brackets 10.

Title: A process for the manufacture of aluminium and its alloys
IPC: C22B4/00
Filed: 1930-05-22
Abstract: A process for the manufacture of aluminium and aluminium alloys consists in first producing from aluminium oxide or materials containing aluminium oxide, under the addition of tungsten-containing substances by means of an electrothermic reducing smelting, a primary alloy containing tungsten and as a second step recovering from this primary alloy aluminium or high grade aluminium alloy.  If pure alumina is used aluminium will be the final product but if impure starting materials are used an aluminium alloy containing impurities of the charge, e.g. iron, silicon, and titanium will result.  The second step comprises cooling and crystallization or liquation, or when producing aluminium, distillation, preferably in vacuo, or an electrolytic refining.  The reduction process is carried out in the presence of a reducing agent, e.g. carbon, with tungsten in the form of metal, alloy or compound such as oxide ore, and fluxes, if desired, so as to give an alloy containing preferably 50-90 per cent of aluminium.  Bauxite containing much iron should first be purified. The solid crystals of the rich tungsten aluminium alloy are separated from the liquid metal by centrifugation, pressing, or similar means and are returned wholly or partly in the process for the production of the primary alloy.  The tungsten-free aluminium or aluminium alloy may be further refined electrolytically.
