Title: Improvements in or relating to the picking up and deposition of articles by aircraft or other moving bodies
IPC: B64D1/22
Filed: 1930-09-24
Abstract: 348,492. Transferring articles to and from conveyances in motion. DRUMMOND, R., 18, Talbot Street, Grangemouth. Sept. 24, 1930, No. 28528. [Class 103 (iii).] An apparatus for transferring packages to or from a moving carrier, such as an aeroplane, comprises a framework 6 which is suspended from the carrier and is fitted with means for holding a container 1 for the package to be deposited and with means for picking up a second container of similar construction, the transfer device being so arranged that the moving container 1 strikes the stationary container, the impact simultaneously releasing the container 1, imparting momentum to the stationary container, and, in addition, actuating the pick-up mechanism. The release and pick-up mechanism comprises a number of two-armed levers pivoted 7 on the framework 6 and adapted to have one set of arms, as shown, pressed into gripping engagement with the nose 2 of the container against the action of spiral springs 11 and retained in this position by pivoted triggers 16 having hooked ends that engage pins 15 on the levers 7. The nose 2 of the container terminates in a highly resilient steel casing 4 enclosing a filling 3 of hard rubber or like material, and abuts against a flexible diaphragm 5 which is mounted in the framework 6 and against which the inner ends of the triggers 16 are adapted to bear. An arm 20 provided with a number of holes 21 serves for the suspension of the framework 6, with its attached shroud 30 and container 1, from the aeroplane &c. In operation, the suspended container 1 is guided at the ground station from the wider to the narrower end 22<1> of a semi-conical member 22, Fig. 3, where the exposed side of the diaphragm 5 is arranged to strike the stationary container. The impact causes a deflection of the diaphragm, pressing back the triggers 16 and releasing the levers 7, which immediately swing over under the influence of the springs 11, release the container 1, and grip the stationary container. When a package is to be transferred in one direction only, the necessary impact for operation of the transfer device is obtained by the use of a dummy container of equivalent weight.

Filed: 1924-12-01
Abstract: 237,206. Crankless Engines, Ltd. July 18, 1924, [Convention date]. Driving-gear.-Relates to mechanism of the type wherein a reciprocatory member carrying universally mounted slippers actuates or is actuated by a swash plate or slant attached to a rotatable shaft, the swash plate being of annular form with cylindrical and concentric inner and outer peripheral surfaces; and comprises an arrangement wherein the reciprocatory member is guided by means of longitudinal bearing surfaces formed thereon adjacent to the slippers and divided into two sections preferably in the form of cylindrical segments, respectively exterior and interior to the annular slant. The guiding means are independent of pistons &c., which may be connected to the reciprocatory member. The invention is shown applied to an arrangement in which the reciprocatory element is unsymmetricaily disposed in relation to the swash plate, as described in Specification 118,098 with reference to Fig. 8 thereof. The swash-plate ring or slant 1 is connected to or integral with a cylindrical rim 6 carried by a member such as a web 10 integral with or attached to the shaft 2a. The slippers 16, 17 embracing the swash-plate ring are universally mounted in a yoke 15 which is attached to the piston stem 14 and is formed with parti-cylindrical bearing surfaces 20, 21, slidabls in fixed longitudinal guides 27, 28, external and internal to the slant 1, the bearing surfaces being co-axial with the piston-cylinder 23. The inner guide 27 extends axially within the rim 6. The swash-plate member may be balanced by forming holes such as 33 in the wider part of the rim 6 and at 34 in the web 10, or by adding weights &c. By disconnecting the swash-plate ring 1 from the rim 6 and breaking the casing joint 29, the casing part 30, together with the contained cylinders, pistons, yokes, and the swash-plate ring, may be drawn off longitudinally with the bearing 31, leaving the rear portion 30<a> of the casing with the shaft 2b in position in its bearing 32. The parts may be lubricated by oil jets directed upon the working surfaces, or oil may be delivered upon the inner surface of the rim 6, being distributed centrifugally at the open end and through passages 35.

Title: Wave guide phase shifters
IPC: H01P1/17
Filed: 1946-09-27
Abstract: 617,381. Wave-guides. WESTERN ELECTRIC CO., Inc. Sept. 27, 1946, No. 28971. Convention date, April 26, 1945. [Class 40 (viii)] A phase-shifter comprises a tubular waveguide 2 provided with one or more internal longitudinally extending fins 3. The latter alter the critical cut-off and the phase velocity of waves whose electric vectors are parallel to the plane of the fin without affecting waves whose electric vectors are normal to the fin. This will normally transform a linearly polarized wave into an elliptically polarized one. In the special cases, however, of 90 and 180 degrees phase-shifters the resulting waves are circular and linear polarized waves respectively. In order to reduce to negligible proportions the reflections caused by the fin, its ends may be tapered as shown at 4 or it may be provided with reduced width quarter-wave impedance matching sections 5. By suitable choice of the length of the fin any residual reflections from the ends can be made to cancel each other. Opposing fin constructions in the guide will cause less disturbance to the fields than the one fin construction shown. In high voltage applications the corners of the fins may be rounded to avoid corona discharge. The section may be filled with solid dielectric and may be rotatable with respect to the rest of the guide. Several rotatable sections with phaseshifters may be arranged in series.

Abstract: 1,270,679. Glass fibre manufacture. COMPAGNIE DE SAINT-GOBAIN. 9 June, 1969 [20 June, 1968], No. 29105/69. Heading C1M. In the production of glass and like fabrics, at least one stream of the molten glass is fed towards and intercepted by rotating blades, i.e. generally flat, thin blade-like or plate-like bodies, each blade carrying by centrifugal force a portion of the molten glass to the outer edge which leaves the edge in the form of a plurality of filaments which are then attenuated to fibres, the direction of feed of the or each stream being transverse to a plane in which the centrifugal force acts. As shown in Fig. 5, a rotor 1 on a vertical shaft 3 is provided with blades 2 and a stream 4 of molten glass, which may be accelerated by a blower 5, falls between the blades 2 which intercept the glass. The end of each blade 2 has points 6, Fig. 4, or channels which subdivide the molten glass to filaments 7. The filaments 7 are then either subjected to a high speed jet of fluid (Fig. 1, not shown) or "soft" flames from a burner 12 which assist in breaking up the filaments 7 to fibres. The fibres are then removed by an annular blower 13. The ends of the blades 2 may be heated by an induction coil 14. As shown in Fig. 6, the blades 27 are on a rotor with a horizontal axis and the stream 4 is subdivided by falling on to a rotating groove disc 24 which projects streams 4a between th blades 27. The rotor has surrounding hot ga jet chamber 25, blower 28 and heater 29 fo attenuating the filaments 26. The blades, besides the points 6, may be arranged to obtain a reserve of glass thereon. As shown in Fig. 7, blade 15 is of concave profile relative to its direction of rotation to give a reserve of glass in cavity 16. Other arrangements include a shield secured to the blade with a through passage. The blades may be arranged along the generatrices of the rotor or may be set at an angle thereto.
