Abstract: 575,578. Screw fans. COLLIERY ENGINEERING, Ltd., and REEVES, H. C. March 21, 1944, No. 5259. [Class 110 (i)] In order that the root b, Fig. 1, of an angularlyadjustable impeller blade a may be made of substantial size and strength without being unduly heavy it is dished so as to be hollow, the hollow being crossed by a stout rib d lying approximately under the blade. The hub of the impeller preferably has a part-spherical periphery and the heel of the blade is correspondingly curved so as to fit it closely at any pitch angle. In the form shown in Fig. 4 the hub is formed of two discs g formed with halfsockets h to receive the blade roots and clamped together, to hold the blades in any position, by bolts passing through bores m, m in the spaces between the sockets; the sockets are formed with grooves j to receive flanges c, Fig. 1, on the blade roots, and have stiffening ribs i. The two discs g are mounted on a metal bush o formed with flats tapering towards its ends to lock and wedge the discs against displacement. The webs k connecting the sockets may be provided in the planes of the outer faces of the discs instead of at the meeting faces. The hub may be provided with a fairing at each end, so that it need not be the full width of the blades. In a modified form, Fig. 5 (not shown), one set of half-sockets is formed on a central. web integral with the nave of the hub and the other set of half-sockets is formed in a removable ring clamped to it. The blade or its root may be formed of thermo-setting synthetic resin; the hub may be of similar material, in which case the half-sockets are provided with metal linings. According to the Provisional Specification, the rib d in the hollow blade root may be intersected by other ribs, and if the hub is formed of synthetic resin it may be provided with a longitudinal radial slot so that it can be clamped on to the metal bush.

Title: Method for producing tantalum carbide and tantalumalloy carbide filaments
IPC: C23C8/20
Filed: 1967-02-03
Abstract: A filament of tantalum, or of a refractory alloy principally comprising tantalum metal, is heated on a carbon support in a non-reactive atmosphere, such as argon, at a first temperature, below the tantalum-carbon eutectic melting point (2800 DEG  C.) but sufficiently high to cause carbon to readily diffuse into the filament, for a predetermined period of time to diffuse sufficient carbon into the filament to raise the melting point of the partially carbided filament above said eutectic melting point but less than that required to form stoichiometric tantalum carbide, then at a second temperature, below the melting point of the now partially carbided filament but above the eutectic melting point, until additional carbon has diffused into the filament to form stoichiometric tantalum carbide, and the tantalum carbide filament formed is then cooled under the non-reactive atmosphere.  A 10 mil. diameter filamentary alloy of 90% tantalum and 10% tungsten, by weight, is coiled, placed on a carbon support, heated at about 1500 DEG  C. for about 15 minutes to remove stress caused by the coiling, carbided by heating at 2600-2650 DEG  C. for about 30 minutes and then at 3100 DEG  C. for 30 minutes, and then cooled to 100 DEG  C.

Abstract: 719,532. Propellers. VOITH GES., J. M. March 2, 1950 [May 17, 1949], No. 5337/50. Class 4 In an oscillating-vane type propeller the maximum vane deflection angle (e max) lies between 50 degrees and 65 degrees, and occurs at a vane traverse angle #, measured from the tangential position, of between 100 degrees and that angle of traverse at which reversal of blade movement would occur with the same angle # max with a "vector intersection vane motion " in which the radius vectors of the vanes always intersect in a fixed control centre, i.e. the reversal point lies within the area bounded in Fig. 2 by the shaded lines and horizontal lines corresponding to ordinates # = 50 degrees and 65 degrees respectively. In the figure curve 10 shows a vane displacement curve in which e max = 64 degrees and occurs at an angle # = 136 degrees, this curve being geometrically similar to the curve 12 for an arrangement with a vector intersection vane motion in which the reversal point occurs at the same traverse angle. A suitable form of vane-operating mechanism may be obtained by appropriate adjustment of the lengths of the lever arms of the linkages between the control centre and vanes of the arrangement shown in Specification 501,467. Specifications 189,751 [Class 4], 232,175, [Class 114], and 262,393, [Class 4], also are referred to.

Abstract: 846,011. Electric indicating - systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 19, 1957 [Feb. 22, 1956], No. 5604/57. Class 40 (1). [Also in Group XXXVI] A Wheatstone impedance measuring bridge comprising four impedances subject to equal variations, two in one sense and two in the opposite sense, and a change-over switch are so connected that in the first position the impedances of each. pair are connected in opposite arms of the bridge so that measuring can take place and in a second position each impedance of one pair is connected in an opposite arm of the bridge to an impedance of the other pair so that the zero constancy of the bridge can be checked. In the embodiment described, four strain gauges 11-14 are attached to the circumference of a ship's propeller shaft 10, Fig. 1, torsion in the shaft causing gauges 11 and 14 to contract whilst gauges 12, 13 elongate or vice-versa. The gauges are connected together to form a measuring-bridge, Fig. 2, energized from source 19 via slip-rings. A measuring voltage #U is taken from the junctions 15, 16 of gauges 11, 12 and 13, 14, respectively, and is supplied via slip-rings to a measuring-instrument, a dot printer or other recording apparatus to measure the torsion of the shaft. To check the zero constancy of the bridge, the gauges 12 and 14 are interchanged to form a testing bridge, Fig. 3, not shown, in which the voltage #U should be zero. If #U shifts from zero in excess of a permissable degree of variation, the shaft is stopped and the bridge re-balanced with balancing impedance elements connected in the bridge arms and carried by the shaft. In Fig. 4 a voltage source 19 is connected via slip-rings 20, 21 to the interconnections of the pairs of gauges 11, 13 and 12, 14, the other ends of gauges 11 and 13 being connected to slip-rings 31, 32 from which diagonal voltage #U is taken. A changeover switch comprising contacts 26-30 is operated by coil 22 connected via slip-rings 24, 25 and switch 23 to a voltage source 33, with the contacts as shown the measuring bridge, Fig. 2, is produced and by closing switch 23 the bridge is changed over to the test bridge. With suitable interchanging of connections to the contacts 26-30 and to the slip-rings an alternative testing-bridge (Fig. 3a, not shown) is produced.
