[Also in Division F4] Hyper-eutectoid iron-carbon alloys with or without other alloying elements are treated to improve their castability and mechanical properties by injecting a rare gas, advantageously argon or helium, in the form of very fine bubbles whereby at least part of the carbon is precipitated in the spheroidal form. Injection may be effected by means of a porous member incorporated into the wall or hearth of a ladle or induction furnace, or by means of a lance. The alloy may additionally be treated with an inoculant such as ferro-silicon, calcium-silicon, or silicon-manganese-zirconiumgraphite .

Abstract: 1521510 Rotor blade pitch adjustment; gas turbine by-pass fan engines UNITED TECHNOLOGIES CORP 14 Oct 1975 [21 Oct 1974] 41999/75 Headings F1C and F1J [Also in Division F2] The pitch of rotor blades 12, e.g. for a ducted fan, are varied by an actuator comprising a harmonic drive 26 having flexible and rigid splines 30, 28 connected to bevel gears 42, 40 engaging diametrically opposite sides of a bevel gear 24 for imparting a couple to the blade root when a non circular wave generator 32 is rotated by gear 38 and differential 36. Bevel gear 42 is splined to flexible spline 30 at 44. As wave generator 32 is rotated it pushes the teeth of spline 30 into engagement with those of spline 28 at two or more points and since splines 28, 30 have unequal numbers of teeth, a rotation of generator 32 causes slight rotation of spline 28 relative to spline 30, this being transmitted as a couple to bevel gear 24.

Abstract: 1,273,858. Echo-sounding. FRIED KRUPP G.m.b.H. 4 Sept., 1970 [5 Sept., 1969], No. 42494/70. Heading H4D. A device for surveying stretches of water from a water vessel comprising measurement of the depth by echo-sounding and the position of the measuring point along a line of survey wherein the measuring point is displaceable in the direction of survey over the whole extent of the water vessel and beyond. In a system for recording the profile of a river bed from bank to bank, an ultrasonic echo-sounder is mounted at a measuring point 3 on a rail 2, fixed in front of a boat 1 which crosses the river transversely. The echosounder is moved along the rail such that as the boat 1 moves a distance A the echo-sounder moves S. The distance s which the echosounder has moved is measured by (1) a measuring cord fixed to one bank and the measuring point 3 (Fig. 6, not shown) (ii) by horizontal echo-sounding, (iii) by a radio receiver on the boat which measures the signal amplitude received from a beacon fixed on the bank. The depth and displacement are continuously plotted on an echograph to produce the profile. In an alternative embodiment the rail is mounted alongside the boat and the ship crosses the river in its longitudinal direction (Fig. 1, not shown). In a catamaran (Fig. 3, not shown) the rail is mounted between the twin hulls. The rail may be mounted on jibs enabling it to be swung into a restposition when away from the survey site. In a further embodiment the echo-sounder is located on the end of a beam which swings from side-to-side (Fig. 4, not shown). In a further embodiment the single movable echosounder is replaced by a number of separate elements which are switched to move the effective measuring point (Fig. 5, not shown).

After separating off the sulphur, the lead acetate solution may be treated with a free CO 2  bearing gas to precipitate insoluble lead carbonate which is recovered. Any undissolved lead salts may be extracted from the sulphur rich residues by treatment with aqueous ammonia in the presence of a low-oxygen content gas, the PbS so formed being re-cycled to the slurry and the ammonium sulphate and ammonium thiosulphate being recovered.

The nitriles may be prepared in fixed or fluidized bed processes. Comparative examples describe the synthesis of acrylonitrile from a propylene, ammonia, steam, air 1 : 1 : 1 : 8 mixture at 480 DEG  C.ALSO:An oxidation catalyst is made from a homogeneous acid solution of a lead salt, a bismuth salt, a soluble molybdenum compound, a colloidal silicic acid sol and a mineral acid which does not form an insoluble precipitate with lead, in the absence of a combination of ammonium ions and phosphorus-containing compounds, by evaporating the solution in such a manner that segregation of the components does not take place and heating the residue to an elevated temperature for several hours. Evaporation may be effected by spray drying.  The catalyst may be deposited on cores of sintered aluminium silicate, corundum, quartz, feldspar, granite, sintered magnesite or silicon carbide so as to form particles 1-8 mm. in diameter and of maximum porosity 10%.  The catalyst may be used in a fixed or fluidized bed.

In a stylographic reservoir pen, a loading member, in the form of a pestle or mushroomshaped member 4, applies a thrust to the drop weight 3 in the direction towards the writing tube 8, even when the pen is held at a writing angle other than vertical. The feed head 2 is screwed into the lower end of a forward barrel portion 1, and is formed with a helical venting channel 12. A removable cup 5 fitted into the bore of the feed head 2 prevents the drop weight 3 and wire 7 from falling out. The mushroom-shaped loading member 4 is located inside the bore above the drop weight, and has its stem extending through an opening 11 in the cup 5. When the pen is tilted from the vertical, the member 4 will tilt since its centre of gravity is located near the upper end of the stem. One edge of the head of the mushroom will bear against the cup 5, and an opposite edge will bear against the drop weight 3 forcing it towards the writing tube 8.

Title: Improvements in hydropneumatic stabilizers and spring suspension devices for motor vehicles
IPC: B60G15/12
Filed: 1960-12-21
Abstract: 931,300. Hydropneumatic spring suspension units; preventing lateral canting. W. LEY. Dec. 21, 1960 [Dec. 23, 1959; June 11, 1960], No. 43971/60. Classes 108(2) and 108(3). A hydropneumatic spring suspension system of a vehicle comprises a pair of suspension elements 34, 35 connected hydraulically to a pressure tank 11 containing a resilient gas cushion through a regulating device 15 which interconnects the pressure tank with both elements during normal vehicle travel but which reduces the hydraulic interconnection with the more lightly loaded suspension element during cornering. In Fig. 1 the suspension elements 34, 35 between the chassis and axle have cylinders 26, 27 containing pistons 28, 29, spring loaded damping pistons 38, 39 and damping piston stop rings 50. The elements 34, 35 are connected by pipes 24, 25 to the regulating device 15 mounted on a pressure tank 11. The tank 11 communicates through passage 14 with the device 15 and contains an elastic bag 12 containing compressed air which acts as a springing medium the pressure of which can be regulated through valve 13. The regulating device contains a double-ended piston 16 with axial and radial passages 18, 17 and an annular groove 19 and a pair of piston centralizing springs 22, 23. Either the pistonrods 30, 31 or the cylinders 26, 27 may be mounted on the chassis but in such a manner that when the vehicle load increases the liquid in the elements is compressed by the pistons 28, 29 and displaced through damping pistons 38, 39, pipes 24, 25 and passages 18, 17 and 14 into the pressure tank. If the left-hand element only is loaded and the other element is unloaded, as when the vehicle rolls, due to the throttling effect of passage 18 piston 16 will be displaced to the right closing off pipe 25 and limiting the degree of roll while the element 34 remains in communication with the pressure tank through annular groove 19. When the loads are equalized the springs 22, 23 centralize piston 16. Under shock loads the damping pistons are depressed cutting off communication with the pipes 24, 25 except through tapered grooves 50a to give progressive damping. In an alternative construction Fig. 4 the suspension elements comprise cylinders 76, 77 containing pistons 78, 79 the liquid spaces below the pistons communicating through pipes 74, 75 and a regulating device 55 with the pressure tank and the gas spaces above communicating through pipes 86, 87 with elastic bag 52 the gas pressure in which is controlled by valve 53 which may be manually adjustable by the vehicles driver. Non-return valves 88, 89 in the walls of the pressure tank and suspension element 77 enable the element to act as a compressor. Damping is provided by discs 64, 65 in recesses in the ends of regulator piston 61.
