Title: Removal of sulphur compounds from hydrocarbon oils
IPC: C10G19/08
Filed: 1947-06-11
Abstract: Alkali solution which has been used to extract acidic sulphur compounds from hydrocarbon oil is reactivated by contacting it with a gas containing free oxygen in the presence of a substance containing a substantial proportion of an aromatic compound containing three hydroxyl groups attached to the carbon atoms of a single benzene ring in positions immediately adjacent to each other.  Compounds which yield such compounds by hydrosic in alkaline solution mal also be used.  Aromatic compounds referred to are tannic acid, gallic acid, pyrogallol, butyl pyrogallol, n-butyro pyrogallol and anthragallol; the effectiveness of these compounds is compared with that of rufigallol and phloroglucinol.  Alkali solutions mentioned are aqueous sodium or potassium hydroxides, to which may be added solubility promoters such as sodium or potassium isobutyrate or naphthenates, alkali metal cresylates and alkali metal salts of the acid oil recovered from alkali solutions used in treating petroleum distillates containing acidic bodies of greater acidity than mercaptans.  The mercaptide sulphur content of the alkali should not be reduced below 0.3-0.6 per cent by weight to prevent destruction of the catalyst.  The regeneration may be effected at 60 DEG -130 DEG F. The regenerated alkali solution may be contacted with steam, nitrogen or other inert gas, or may be washed with a solvent, for example a light hydrocarbon liquid such as naphtha, other petroleum distillates, benzene and cyclohexane, prior to re-use.  Oils treated may be petroleum distillates such as those in the gasoline boiling range.

Title: Improvements in apparatus for cleaning small articles such as watch parts and other small parts of machinery
IPC: G04D3/08
Filed: 1938-08-24
Abstract: 518,523. Cleaning metals. LANZETTER, S. Aug. 24, 1938, No. 24859. [Class 82 (ii)] [Also in Group XVIII] In apparatus for cleaning small articles of the type in which the articles are carried in a wire basket mounted on the end of a spindle driven by an electric motor and the apparatus is adapted to be inserted in turn in a number of receptacles containing the cleaning liquid, the motor spindle or a sleeve surrounding this spindle slides through a cover for the receptacle to enable the basket to be raised above the surface of the liquid without removing the lid or cover from the receptacle. In Fig. 1 the motor B that rotates the basket A is mounted on a bracket B<1> sliding on the pillar D fixed on the lid E. A spring pin d secures the bracket in the raised position and a keyway d<5> prevents rotation thereof. The basket A containing the articles is spun in the cleaning liquid, then raised and spun above the liquid so as to dry the articles without splashing. Baffles may be attached to the bottom of the motor casing and pass through slots in the lid, to depend into the liquid and promote turbulence when the basket is rotated. In Figs. 5 and 6 the bracket B<1> is raised by a pulley b<2> and cable b<1>. The pulley is provided with a catch so that by one revolution of the pulley the basket is raised and fixed at the " spinning-off " position and by a second revolution the basket is raised above the receptacle C together with the lid by means of the rod e<4>. Then the turntable E2 turns round the central pillar D and another receptacle comes beneath the raised basket. One of the receptacles C<1> may contain a heater for drying the articles. The rod d<4> engages with the bracket B<1> and prevents it from rotating. The blades c<2> mounted loosely on the spindle act as baffles and are prevented from rotation; by the rod c<3> attached to the motor casing, a spring catch e<6> engaging in notches e<5> maintains the turntable in one of the fixed positions. A switch e<8> is provided for the motor so that the direction of rotation of the basket may be reversed after a given number of revolutions. The basket may have several compartments which may be nested one within another or may be segmental in shape. In another form the spindle is surrounded by a sleeve attached to the motor casing and sliding through the lid of the receptacle. A felt pad is provided between the sleeve and spindle to prevent loss of liquid up the sleeve. In a further form rods depend from the motor casing and pass through the receptacle lid having nuts on the end of them. A spring surrounds each rod and maintains the motor and basket normally in position for spinning off. Nuts on the ends of the rods enable the lid to be lifted off when the motor casing is raised.

Title: Improvements in or relating to Systems for Supplying Fuel to Aircraft Engines
IPC: B64D37/22
Filed: 1967-06-01
Abstract: 1,186,577. Valves. INTERTECHNIQUE. 1 June, 1967 [6 June, 1966], No. 25224/67. Heading F2V. [Also in Division F1] Fuel is supplied to piston-type or jet-propulsion aircraft engines by a fuel pump of which the intake side communicates with two fuel admission orifices located at different points of a fuel tank and each controlled by a valve, the two valves being mechanically coupled together and operated by positive control means constituted by an hydraulic control system supplied with fuel under pressure by the fuel pump and operated in dependence on the flight conditions, in order to close the admission orifice which would not be submerged in the fuel. The fuel pump shown in Fig. 3 is submerged in a fuel tank and comprises an inlet duct Fa having a lower inlet opening Ga and an upper inlet opening Ha controlled by valves Ia and Ja respectively, the valves being interconnected by a common stem 1a so that when one valve is open the other is closed. During normal flight, fuel at delivery pressure is communicated from the pump volute Ca via restrictors 29, 30 and a line 23 to the space above a diaphragm 21 attached to the valve Ja, while the space below a diaphragm 7a attached to the valve Ia is vented to the interior of the tank via a line 22, an open valve 27a and a passage 25. Under conditions of inverted flight or negative gravity when the normal inlet Ga is not submerged, a plunger 27 carrying the valve 27a and a valve 27b reverses its position, thereby closing the valve 27a and opening the valve 27b. The space above the diaphragm 21 is consequently vented to the interior of the tank and the space below the diaphragm 7a is exposed to the fuel delivery pressure, and the valve Ja is therefore opened and the valve Ia is closed. In a modification, Figs. 1 and 2 (not shown), the diaphragm 21 is replaced by a spring (3) urging the inlet valves into the normal positions in which the upper inlet is closed and the lower inlet is open, a gravity operated valve (11a) being provided to admit fuel at delivery pressure to the space below the diaphragm (7) to reverse the positions of the inlet valves.
