Patent GB-1099454-A (GB)
Title: Reforming hydrocarbons
Inventor: DAVIES PHINEAS
IPC: C01B3/38
Filed: 1963-10-23
Abstract: A process of reforming hydrocarbons includes the stage of passing a gaseous mixture containing one or more vaporized hydrocarbons and oxygen over a catalyst comprising a metal of Group VIII of the Periodic Table on a compound thereof supported on alumina-containing material made by reacting an intimate mixture comprising Al2O3 and aluminium metal in particulate form with a reagent capable of forming Al2O3 from Al metal.  The gaseous mixture normally contains steam or carbon dioxide or both before reaction and is preferably a primary reformer gas mixture.  In an example the inlet gas consists of H2, CO, CO2, CH4 and excess H2O (steam).  The rate of oxygen admission was controlled to yield an NH3 synthesis gas.

Abstract: 1,200,795. Adjusting mechanism for brakes; clutch control. BORG-WARNER CORP. 26 Sept., 1967 [10 Oct., 1966], No. 43835/67. Headings F2E, F2F and F2L. In a fluid-operated brake or clutch, a lever 13 is pivoted at 35, an adjustable length member 45 being interposed between an actuator 10 and the lever 13 and a spring 50 frictionally engaging the adjustable length member 45 and arranged to provide automatic adjustment of the effective length of member 45 whenever lever 13 is moved beyond a predetermined limit. As described, the brake is applied by injecting hydraulic fluid into chamber 20, the resulting movement of piston 12 causing anticlockwise movement of lever 13 which is coupled by a strut 14 to the band brake of an automatic transmission. The brake is released by a spring 22 or by injection of fluid into chamber 21. If the friction members should become worn, an arm 51 of a helical spring 50, wrapped around the thread of bolt 45, engages the upper arm 32 of a V-slot so that the spring 50 will be loosened and moved anticlockwise relative to the bolt 45. On release of the brake, the arm 51 will engage the lower side 33 of the V-slot, tightening the spring 50 on the bolt 45 and thus rotating it so as to compensate for brake wear. In Fig. 6 (not shown), the arm 51 has a U-shaped end, the sides of which engage a tapered or cylindrical pin (Figs. 5, 7, not shown) replacing the V-slot of Fig. 1.

Abstract: 952,785. Axial-flow fans. AEREX Ltd. Nov. 15, 1962 [Dec. 7, 1961], No. 43837/61. Heading F1C. In a fan blade with an integral root stub having a terminal flange, and a clamping ring which bears axially, with respect to the fan blade axis, against the root stub flange, the flange and the clamping ring aperture are so shaped and dimensioned that by relative tilting and turning, with their axes inclined, the flange can be passed through the aperture but is axially opposed to the bearing surface of the clamping ring when the ring is on the root stub and coaxial therewith for attachment to a fan hub. The fan blade 2, Fig. 1, has a root stub provided with a flange 4 in the periphery of which is arranged, inclined to the blade axis, a notch 8 of a depth substantially equal to the radial projection of the flange 4 from the root stub, and of a width slightly greater than the thickness of the flange 6 of a ring nut 3. The ring nut 3 is put over the flange 4 by presenting the root stub to the circular mouth 5 of the ring nut 3 in an inclined position, with the notch 8 straddling the flange 6, and then turning the ring nut 3 until it has passed over the flange 4. The ring nut 3 is then screwed to a stub shaft 1 which projects radially from the fan hub (not shown) and which is rotatable to vary the pitch of the blade 2. A locking-nut 7 is provided. In an alternative embodiment, Fig. 6, the ring nut 3 is replaced by a clamping ring 9 which is secured.to a flange 10 on the stub shaft 1 by at least three bolts 11. Alternatively, the flange 4 may be boat-shaped with a maximum width slightly less and a length substantially greater than the diameter of the circular aperture of the clamping ring, one end of the boat-shaped flange being substantially full-width, to be passed first diametrally on the slant through the aperture, and the other end having a curved taper, from the sides and beneath, so that it can follow through the aperture as the blade is brought into a position axially parallel with the clamping ring axis. The aperture in the ring may instead be notched or otherwise shaped to enable it to be passed over a complete circular flange on the blade root stub.

In a spinning extruder for melting synthetic thermoplastic material, and extruding the melt through spinnerets wherein a spinning pump between the extruder screw and the spinneret, and directly in front of the spinneret, acts as a metering means, the length of the metering zone is at least 12 times the diameter of the screw of the extruder in the metering zone, and the thread depth of the screw on the metering zone is at least 3.5% of the screw diameter. The simultaneous lengthening of the metering zone and increase of screw thread depth eliminates pressure variations in the melt and allows the spinning of uniform filaments with titre deviation less than 1%. Optimum effects are obtained using an extruder screw of total length 24 diameters, of which 12 are in the metering zone the thread depth being 4-5% of the screw diameter.
