Title: Variable pitch propeller or rotor
IPC: B64C11/06
Filed: 1961-12-14
Abstract: 976,296. Variable pitch propellers and rotors; convertible aircraft. H. T. GRUT. Nov. 16, 1962 [Dec. 14, 1961], No. 44804/61. Headings B7G, B7V and B7W. A propeller or rotor has two or more blades, each comprising a rigid rod 1 extending radially from a central hub 10 and a shell 2 of airfoil cross-section mounted thereon fixed against longitudinal displacement and a bevel-gear drive 7 and 8, splined to the root of the shell at 11, so that a torque may be applied to the shell 2 to angularly displace and twist it relative to the rod 1 and rotate the blade about its longitudinal axis. The rod 1 also comprises at least one continuous longitudinal ridge 5 having stop surfaces 3 which collaborate with stop surfaces 4 inside the shell 2 for limiting the angular displacement of the shell in different positions of angular adjustment allowing different transverse sections of the shell different degrees of displacement relative to the rod 1. This arrangement is facilitated by varying the form of the ridge 5 so that cross-sections of the shell 2 can rotate through progressively increasing angles taken from the blade tip to the blade root. Fig. 5D shows an arrangement for locking the rod 1 and shell 2 in different angular positions. A slide 15, having notches 17, moves longitudinally in a slot in the crest of a ridge 5 to trap pins 19 and prevent relative movement of the rod and shell. A further embodiment describes the use of a pressure fluid to exert a torque on the shell by acting in opposite spaces between the rod and shell. Another embodiment described a shell formed from transverse slabs, keyed to each other to allow relative movement, and covered with an external resilient skin. The torque is transmitted through the slabs from blade root to tip by the keys and keyways which are formed with the required clearances. Fig. 8C shows an aircraft for which the propeller is stated to be suitable. It comprises an engine 20 in the fuselage driving the propellers through shafting and reduction gears 23 and a hinged tail skid 21 which can support the aircraft in a vertical position. The wing and propellers can be rotated for vertical and horizontal flight. Specification 880,590 is referred to.

Abstract: 1529449 Colour diffusion transfer neutralization retarding layer AGFA-GEVAERT AG 30 Oct 1975 [26 Nov 1974] 44909/75 Heading G2C A neutralization system, for the colour diffusion transfer process, comprises (1) a neutralization layer comprising a polymer containing free acid or acid anhydride groups and (2) a retarding layer which retards neutralization and comprises a hydratable polymer or polymer mixture, comprising a homo-, co- or graft polymer of, 1, 2- dimethoxy-ethylene or a mixture of these polymers, which acts as a barrier against diffusable OH ions, this barrier being independent of temperature or inversely related to temperature and being effective during a first time interval under the action of developer alkali and then becoming negligible owing to hydration during a second time interval which is less than half as long as the first time interval. The first time interval may be at least 1 minute. The polymer or polymer mixture of the retarding layer preferably has a quotient (barrier time of non-hydrated polymer divided by that of the hydrated polymer) of at least 10. The retarding layer is preferably not more than 20Á thick. The retarding layer preferably contains a polymer of at least 80 mole % 1, 2-dimethoxy-ethylene and 0-20 mole % of one or more of an alkyl vinyl ether, 1-methoxy-2- ethoxy-ethylene and 3,4-dimethoxy-3-buteryl acetate. Specified polymers are of 1, 2-dimethoxyethylene, optionally copolymerized with ethyl vinyl ether, isobutyl vinyl ether, or 1-methoxy-2- ethoxy-ethylene. Known retarding layer polymers, in so far as they are hydratable at all, do not have a complete barrier action in the non-hydrated state and are not completely permeable to diffusible OH ions in the hydrated state as in the present invention.

Abstract: 1,245,858. Transfer mechanism. BURROUGHS CORP. 15 Sept., 1969 [16 Sept., 1968], No. 45441/69. Heading G4D. Each order of a register has a transfer pawl with two degrees of freedom, one of which permits two discrete positions relative to the register shaft, one of these positions coupling the higher order pinion to the shaft. The pawl 45 normally rides on the inner edge of a ring secured to the associated pinion, Fig. 7. If the pinion passes from 9 to 0, or vice versa for subtraction, pawl 45 is depressed to intermediate position by cam 21D. Subsequently the shaft 23 is turned through 36 degrees so that cam 21E depresses pawl 45 fully. A slide 41, Fig. 2, then moves to the left to rock any displaced pawls 45 so as to engage the pinion of next higher order, restoration of the shaft 23 then effecting transfer. If any pinion is standing at 9 (or 0 for a subtractive operation) then pawl 45 is depressed to intermediate position by 21D and a projection 45B is aligned with an interposer 47. If transfer is effected to this pinion then the interposer 47 rocks this pawl 45 also to effect transfer to the next denomination. Carry from the highest denomination to the lowest via slide 51 provides for the fugitive one.

Abstract: 1439910 Welding by fusion MAHLE GmbH 22 Oct 1974 [31 Oct 1973] 45697/74 Heading B3R [Also in Division H5] In electron beam seam welding, e.g. of an annular seam between a piston body 5 and a piston ring carrier 7, beam penetration is measured by means which senses those X-rays radiating from the welding region of the beam which extend normally of the beam. As shown, a workpiece piston assembly 5, 7 is mounted on a rotary support 4 the axis of which is parallel to the beam 2 of a gun 1. Disposed between and in parallel with the beam and an X-ray film 7 is a series of spaced parallel plates 12, preferably of lead, having series of respectively aligned bores (14 or slots) of equal diameter. In operation, only those X-rays which are normal to the beam pass through the bores to impinge on the film to indicate beam penetration T, the other X-rays being absorbed by the plates. The spacings between the plates may differ. Alternatively, for continuous read-out, the X-rays may be arranged to impinge on a photoelement sensitive to X-ray intensity above a given threshold value, and signals from such an element may be used for automatic control of the welding to ensure a predetermined seam depth.
