Title: Process for preparing aviation fuels
IPC: C10L1/06
Filed: 1955-10-27
Abstract: A mixture of liquid hydrocarbons suitable for use as an aviation fuel component is prepared by separating from a naphthenic straightrun gasoline, a fraction having an initial boiling point of 65 DEG  C. and a final boiling point between 130 to 140 DEG  C., catalytically reforming this fraction and mixing the reformate with all or part of the fraction of the gasoline boiling below 65 DEG  C.  The gasoline may be such that the fraction boiling between 65 DEG  C. and 85 DEG to 95 DEG  C. contains 15 per cent by weight of normal hexane.  The catalytic reforming treatment may be carried out using as catalyst platinum supported on alumina, silica-alumina or silica-magnesia, molybdenum oxide supported on alumina, or chromium oxide supported on alumina, at a pressure below 50 atmospheres and at a temperature between 450 DEG  and 525 DEG  C. When the reformate has been mixed with the fraction boiling below 65 DEG  C. pentane and lighter hydrocarbons present in the mixture may be removed.  A fraction boiling above 105 DEG  C. may be separated from the mixture and a portion of it returned to the resulting mixture in an amount not exceeding 10 to 20 per cent by volume of the reformate-containing product.  The liquid hydrocarbon mixture may be blended with an alkylate prepared from isobutane and a mixture of butenes and pentenes, and with isopentane and butane, so that the resulting product contains at least 30 per cent by volume of the mixture of reformate and fraction boiling below 65 DEG  C., and less than 50 per cent by volume of the alkylate. Tetra-ethyl lead may be added to the compositions.  Examples of the process are given.

Title: Control device for hydraulic drives
IPC: F15B13/06
Filed: 1962-08-14
Abstract: 979,820. Hydraulic apparatus. KAMPERMASCHINENBAU G.m.b.H. Aug. 14, 1962 [Aug. 14, 1961], No. 31197/62. Heading F1P A control device for pump-fed hydraulic drives comprises selector valves 1, 2 for controlling the drives, a pressure relief valve 10, 16 and an unloading device 5 between a pump conduit P and an outlet pipe 4, the unloading device having a piston which is subjected on one side, to pump pressure and, on the other side, to the pressure downstream of an axial bore 6 and the force of a spring 8, the outlet pipe 9 being open when the plungers of the selector valves 1, 2 are in their neutral position so that the device 5 unloads the pump to a tank T and being closed upon displacement of the plungers so that the unloading device disconnects the tank and increases the pressure supplied by the pump. The control device acts to limit shock waves in the system when the selector valves are moved from their neutral positions to actuate the hydraulic drives. In the neutral position of the selector valves, the outlet pipe is unblocked and pressure from the pump conduit P acts on the piston 5, the flow of fluid through the bore 6 causing a lower pressure to act on the other side of the piston and in the outlet pipe 9. The pressure acting across the piston moves the piston upwardly against the spring 8 to connect the pump conduit to a tank T. When one of the plungers is moved from its neutral position, the outlet pipe 9 is blocked and the equalising of the pressure across the piston permits the spring to move the piston towards its seating to disconnect the pump conduit from the tank and increase the pressure from the pump. The pressure increase follows an exponential curve and is determined by surfaces 13 on the part of the piston which engages the seating, and shocks are prevented by pressure-relief valve 10, 16 opening before the piston closes the passage to the tank.

Filed: 1925-12-10
Abstract: 262,931. Cooper, A. J., and Bilney, A. A. H. Dec. 10, 1925. Hinges.-In a hinged joint in which the pivot carried by one member of the joint is seated in bridge-like housings on the other member of the joint the material adjacent to the housing is slit so that the material to one side thereof is movable to permit of the passage of the pin into the housing. The application of the joint is described for the lid of a tin box, shown in Fig. 1, and for mounting the handle of a paint pot, shown in Fig. 4. The lid 10 is formed integral with a T-piece having a channelled head 13, Fig. 1, to serve as the hinge pivot. The housings or socket members 16, 17 are formed on the rear wall 14 of the box, with a part 18 offset inwardly to allow the hinge to work freely. A slit 19 extends to the edge of the material adjacent to the mouth of the housing and at right angles to the axis of the pivot. To assemble the parts, one end of the pivot pin is inserted in the housing 16 and pressure is applied to open the slit 19 and permit of the other end of the pivot being inserted into the housing 17, the displaced metal springing back into its normal position. A slit may be made adjacent each housing, and for each housing there may be more than one slit, but it is preferred that the material adjacent each housing is left unslit through at least one half of its outline. The handle 30 of a paint pot, Fig. 4, is hinged to loops 29, each of which has its ends seated in housings 31, 32, the metal being slit at 33.

Title: Improvements in bearings
IPC: F16C17/03
Filed: 1931-11-14
Abstract: 376,153. Tilting pad bearings. AKTIEBOLAGET NOMY, 2, Norrmalmstorg, Stockholm. Nov. 14, 1931, No. 31574. Convention date, Nov. 14, 1930. [Class 12 (i).] A tilting pad bearing has means to cause a pivotal movement of the pads about an axis different from the tilting axis for the automatic adjustment of the pads into their tilted positions corresponding to the direction of rotation. As shown for a bearing with two rows of pads 3, Figs. 2 and 7, the bearing surface 5 of the bearing ring 4, the perimeter of the supporting driving ring 2 and the co-operating faces of the pads 3 are spherical. Each pad 3 has a pair of ribs 7, 7<1>, and the driving ring pairs of grooves 10, 10<1>, each pad being pivoted on a pin 8 carried by the driving ring 2. Rotation of the shaft in either direction causes each pad to pivot on the pin 8 to a position in which the pad edge 12 engages a rib 11 on the ring 2 so that one of the ribs 7 crosses a groove 10 while the other rib 71 overlies and tilts into the other groove 10<1> thus forming a space between the bearing faces of the pads and the ring 4 for wedge lubricant films. The pins 8 may be located at or slightly to one side of the centre of gravity of the pads and the grooves 10, 101 may be formed in the pads and the ribs 7, 71 on the driving ring. In a modification, the pivotal movement of the pads upon reversal in the direction of rotation is caused by friction set up by a member 16, Fig. 10, which is spring- urged against one side of the pads 3. The extent of the pivotal movement is limited by pins 20 on the driving ring 2, each pin engaging an arcuate groove 21 in a pad. Two members 16 may be incorporated in one bearing. In a modification the member 16 is omitted and the pins 8 are arranged to one side of the pad. This construction may be modified by omitting the pins 20 and grooves 21, the pivotal movement being limited by flanges on each side of the ring 2. The invention may be applied to bearings having non-rotatable pads.
