Title: Method of and device for etching aluminium foils
IPC: C23F1/20
Filed: 1952-02-13
Abstract: 709,537. Etching. ALUMINIUM-WALZWERKE SINGEN GES. Feb. 13, 1952 [Feb. 14, 1951], No. 3871/52. Class 100 (2) In a method of etching aluminium foils, for the purpose of increasing their active surface, the foils are roughened in a first step in an etching bath and are then further roughened in one or more other etching baths in succession ; the aggressiveness of the etching solution being reduced from bath to bath. The aggressiveness of the solution may be reduced by lowering the temperature or by lowering the concentration of the solution. As shown, a pickled aluminium foil is drawn through three acid troughs 1, 2, 3 over glass or china rollers 5. Contact chronometers 6 may control automatically the heating and cooling of the troughs by means of relays. Steam nozzles 7 effect the heating, whilst water sprays 8 effect the cooling. The etching solution may be moved in the opposite direction to that of the foil. In one example the foil is roughened in the first stage for 110 seconds in a warm bath at 30‹ C. of 400 c.c. of 32 per cent HCl, 100 c.c. of concentrated HNO 3 , 100 gms. FeCl 3  and a litre of water containing 15 grams of aluminium. Second stage etching is effected for 120 seconds at a temperature of 25‹ C. by a solution of 10 per cent HCl containing 10 gms. of aluminium per litre. The etching may be promoted in one or more stages by the use of direct or alternating current. The invention is applicable to batch etching as well as continuous etching.

Title: Method for pyrolyzing solid carbonaceous materials
IPC: C10B49/16
Filed: 1963-01-30
Abstract: <PICT:1023491/C4-C5/1> A method of producing an effluent, vapour from a solid carbonaceous material, e.g. oil shale, comprises hydrolysing the shale in a zone 8 by contact with hot heat-carrying bodies, recovering vapour, at 16, from the zone, separating spent solids from the bodies and transferring the bodies to a pebble heater 20, i.e. a chamber in which the bodies pass downwardly in counter-current to a heating medium, the heat of the medium being derived from the spent solids under non-combustion conditions and from combusting a fuel, and recycling the bodies to the zone 8. Crushed shale is delivered to a lift heater 4 supplied with hot flue gases from the heater 20, and is passed via line 6 to a rotating drum 8 to which the heated bodies are delivered via lines 9, 10.  A screen 12 permits hot spent solids to pass by line 13 to a gas lift 24 where the solids heat air from a blower 25, the heated air, at about 700 DEG  F., burning a gas oil fraction, derived from the effluent vapour, in a zone 50 of the heater 20 to which the bodies have been delivered via lines 15, 17, 18, 19 from the drum 8.  The bodies may comprise iron, steel, alumina, or ceramic compositions or spent ash, and materials treated include bituminous sands, lignites, coal and peat.  Pyrolysing temperatures are 750 DEG  to 950 DEG  F., preferably 800 DEG  to 900 DEG F. Instead of the entrained solids gas lift 24, the air may be preheated by the spent solids in a fluidized bed or by a pebble heater (as defined above).  A non-combustion supporting gas may replace the air, oxygen being introduced therein after heating and before combustion in zone 50.  The fuel burnt in the zone 50 may be any solid, liquid or gaseous material, whether derived from the pyrolysis process or not.

Title: Improvements in and relating to means for automatically controlling the variable speed gearing of motor vehicles
IPC: F16H61/02
Filed: 1926-02-12
Abstract: 270,804. Kirkby, T. M. Feb. 12, 1926. No Patent granted (Scaling fee not paid). Automatic power control; controlling different functions by same lever.-The change-speed gear is automatically controlled by the action thereon of relative displacement between a roadwheel axle and the spring-supported frame or body, this displacement being due either to the weight of the load or to the resistance to motion of the vehicle. In the construction shown in Fig. 1, one arm 4 of a bell-crank lever pivoted at 5 on the axle casing 6 is connected by a link 8 to the chassis frame 9, and the other arm 3 is connected by a rod 1 and a crank 21 to a cam 19 acting on the gear lever 2. Any relative movement between the axle and the frame rotates the bellcrank lever and thereby causes the rod 1 and the cam 19 to move the gear lever and change the gear. The main clutch 17 is disengaged and reengaged at each gear-change by means of a toothed member 12 which is fixed on the rod 1 and acts on the clutch through a bell-crank lever 14. The throttle may also be connected to this bell-crank lever. Small movements of the rod 1, insufficient to change the gear, partly disengage the clutch and cause it to slip, thus easing the drive. A spring 49 is inserted in the rod 1, or a dash-pot may be provided, to prevent actuation of the gear by immaterial relative movements of the frame and the axle. A cable or cables may be employed instead of the rod 1.

Title: Improvements in or relating to dewaxing hydrocarbon oils
IPC: C10G73/06
Filed: 1938-02-10
Abstract: <PICT:0492017/III/1> In a continuous process for removing wax from oils, the oil is mixed with a solvent and chilled to precipitate the wax.  The chilled mixture is then given an addition of previously dewaxed oil to increase the ratio of oil to wax, and finally passed into a rotary filter.  The lay-out of apparatus for carrying out the process is indicated in the Figure.  Oil containing about 25 per cent by volume of wax is led to a mixer 2 via a pipe 1.  A dewaxing solvent consisting of about 40 per cent methyl ethyl ketone and 60 per cent benzene, is led into the mixer via a pipe 3.  The mixed oil and solvent may be passed directly into a chiller 5, or may be passed into a heater 4 before entering the chiller 5, where the temperature is lowered to about -28 DEG  C.  The chiller causes wax to be precipitated and the oil containing the precipitated wax is passed into the rotary filter 7.  Previously dewaxed oil is also passed into the filter 7, via either the pipe 8a or the pipe 6.  If the pipe 8a is used, some of the dewaxed primary filtrate is recirculated into the filter.  If the pipe 6 is used, oil which has been extracted from the wax cake of the primary filtrate by the aid of the mixer 10, chiller 13, filter 14 and tanks 15, 16, is used.

Title: Improvements in destructible forms particularly for the manufacture of fuel tanks and other articles
IPC: B64D37/02
Filed: 1944-03-14
Abstract: 575,801. Cores for moulding. GRENEKER, L. L. March 14, 1944, No. 4755. Convention date, March 30, 1943. [Class 87 (ii)] A hollow destructible core, which may be used for moulding indiarubber fuel tanks, is made of plaster of Paris or other frangible material reinforced by plasterboard and by a rope which is embedded in the frangible material, the walls of the core being so thin where the rope is embedded that pulling out of said rope breaks the form into pieces which may be withdrawn from the fuel tank through an opening in the latter. Specification 574,211 is referred to. Fig. 9 is a section through a corner of a three-part mould, Fig. 8, in which the core has been cast, the core comprising plaster 36 in which cheesecloth or paper burlap reinforcement 39 is embedded, plasterboard 53, 56 and rope 62. The outside of the core may be covered with paper glued thereto ; or paper or cloth may be laid first in the mould to form the outer surface of the core, in which case the cheesecloth &c. may be omitted. The plasterboard may be in sections small enough to pass through the fuel tank opening after the core has been disrupted, or the sections may be too large to pass through, in which case they are broken into smaller pieces in the tank. To facilitate breaking, the sections may be cut partly through, as along lines 49, 50, 51, Fig. 6, which is a plan view of the lower part of the mould with the core cast therein. To hold the plasterboard 53, 54 firmly in contact with the curved mould walls, sticks 58 may be wedged therebetween until the plaster sets. Additional reinforcement comprising rope, fabric and plaster may be applied to the inside of the core. Fig. 3 is a view of the underside of the lid 14 of the mould. The lid includes a boss which forms an opening in the core. As shown, the rope is disposed in coils and has free ends 62a which are grasped to disrupt the core. The mould base comprises two parts 20, 21, held together by clamps 30, 31, and lugs 24 fit into recesses 25 in the lid. The two core parts are cast in the basÚ and the .lid, and the latter are assembled, whereupon the core parts coalesce.
