Title: Improvements relating to rotary wing aircraft
IPC: B64C27/54
Filed: 1961-09-29
Abstract: 1,006,705. Rotary wing aircraft. L. BOLKOW, [trading as BOLKOW-ENTWICKLUNGEN KOMM.-GES.], Sept. 29, 1961 [Oct. 1, 1960], No. 35157/61. Heading B7W. A rotary wing aircraft comprises blades that are positively pivoted about their lag-lead axes, and linkwork for setting the pitch angle of each blade independent of its movement about its lag-lead axis. The lag-lead drive mechanism is not shown. In Fig. 1, an arm 1 on the rotor hub has a forked end la in which a blade 3 is mounted on a lag-lead axis I-I. A shaft 8 journalled within the arm is connoted by lever arm 7 and rod 6 to a swash plate 5, and links 10, 11, ball jointed at 12 are pivoted about axes A-A and B-B to a lever 9 on shaft 8 and a horn 3a on the blade respectively. The axes A-A and B-B are equidistant from axis I-I, and links 10 and 11 are of the same length. Tilting of the swash plate changes the blade pitch, which is unaffected by lag-lead movement of the blade. In Fig. 3, a frame 16 hinged at 14 is moved, parallel to itself in response to tilting of the swash plate, by parallel links 13, 15, the former secured to shaft 8 and the latter freely pivoted in arm 1. A link 17 is pivoted to the frame on axis C-C, and is ball jointed to horn 3a at 18. The distance between axis I-I and hinge 14 equals the length of link 17, the distance between axis I-I and the centre of joint 18 equals the length of frame 16, and the effective length of horn 3a equals that of links 13 and 15. With axis C-C parallel to axis I-I, lag-lead movements do not produce pitch alteration. In Fig. 4, the shaft 8 is outside the hub arm 1, and is'connected to a plunger 28 passing axially through the lead-lag hinge by a ball-jointed arm 26 and link 27. A lever 30 is pivoted at its centre to the plunger. One end of the lever is tied by link 31 to a fixed arm 32, and the other end is connected to the blade pitch control horn 34 by link 33. The blade pitch is again unaffected by lead-lag movements.

Title: Cylinder for printing press delivery mechanism
IPC: B41F21/10
Filed: 1954-12-09
Abstract: 754,424. Sheet delivery apparatus; folding paper. GOSS PRINTING PRESS CO. Dec. 9, 1954 [June 29, 1954], No. 35681/54. Class 100(1). A product-handling cylinder for a print press delivery mechanism having product-engaging elements operating in synchronism with rotation of the cylinder for picking up and releasing products at different points is characterized in that the cylindrical surface is wholly made up of a plurality of curved plate-like elements which are capable of a depressible movement under pressure exerted by a wad of paper resulting from a choke in the delivery mechanism thereby to provide clearanace for choked products. A web 23 (Fig. 1) is cut by cylinders 24, 25 and the severed products passed to a cylinder 30 having pins 31 and Leicher blades 32 the lathe co-operating with jaws on cylinders 40, 41, from which the folded products are delivered to cylinders 45, 50, co-operating with slitters 47, 55, and finally to delivery belts 21, 22 respectively. The cylinders 40, 41 each include two sets of laminated jaw blades 60 (Fig. 2) pivoted on a pair of shafts 62. The jaw blades engage stationary abutments 63 and are oscillated by cams 66 on a shaft 65 which co-operate with cam-followers 67. The shaft 65 may be rotated as described in Specification 747,444. The cylinder has a centre portion 77 on which is mounted the jaw-operating mechanism. The cylinder also includes two rims on which are pivoted a set of curved plates 81, 82 ... 86. The plate 81 is mounted on pivot pins 94 supported in grooves 96 (Fig. 5) formed in the periphery of the rims of the cylinder. The pins are held in position by segments 97. Coil springs 100 serve to urge the plate 81 outwardly, the plate being held against the action of the springs in its normal position by arcuate stop members 102 (Fig. 6) bolted to the rims of the cylinder and having overhanging lips 105 which register with grooves 106 formed in the plate 81. Fastened to the forward edge of the plate are the stationary jaws 65, and between the jaws 63 are clearance grooves which permit the passage of the grippers on the co-operating cylinders 45, 50. The plate 84 is of the same construction as the plate 81 and the plates 83, 86, which immediately precede the jaws 60 are provided with clearance grooves at their trailing edges which register with the grooves on the leading edge of the plates 81, 84. All the plates 81, 82 ... 86 are pivoted in the same manner as the plate 81. In operation, should the products become choked to form a crumpled wad between the cylinders 40, 41 and 45, 50 respectively, no damage occurs owing to the wad depressing one of the plates 81, 82 ... 86 and passing between the cylinders.

Title: Process for the manufacture of compounds of the cyclo-pentanopolyhydrophenanthrene series
IPC: C07J75/00
Filed: 1936-12-30
Abstract: Compounds of the cyclopentanopolyhydrophenanthrene series which are substituted on position 17 by an oxygen atom are treated with organo-metal compounds obtained by the interaction of the metal, preferably zinc or magnesium, with halogen methyl ethers or esters. The preferred ethers have the general formula Hal.CH2.O.R, where R indicates an aliphatic, aromatic or alicyclic radical.  Particularly suitable are the chloromethylmethoxyalkyl-ethers Cl.CH2.O.CH2.OR where R may be either an alkyl or an aryl group.  The employment of these materials leads to the formation of aldehyde groups on position 17 of the nuclear system through the intermediate formation of the corresponding glycol monoesters or ethers followed by either acid or alkaline hydrolysis.  The organo-metal compounds may be used either in the form of finished reagents or in the form of their components. The latter course is desirable when dealing with relatively unstable compounds.  The 17-aldehyde compounds produced as just described may be further reacted with organo-metallic compounds to yield pregnendiol for use as a source of Corpus luteum hormone.  The 17-aldehyde compounds are purified by conversion into derivatives with the usual aldehyde reagents such as semicarbazide, thiosemicarbazide, and phenylhydrazine.  In an example magnesium chloro-dimethyl ether is reacted with androstenolone acetate, and the grignard compound decomposed with acid in the usual way.  Excess of androstenolone is removed by means of semicarbazide acetate, and the product is heated for 3 hours with anhydrous formic acid to yield androstenol-3-aldehyde-17.  Instead of formic acid, there may be used for the saponification either oxalic acid or dilute sulphuric acid. Pregnendiol is obtained from the androstenol-3-aldehyde-17 by the action of methyl magnesium iodide.

Abstract: 845,069. Compressed-air engines. GEWERKSCHAFT EISEWHUTTE WESTFALIA. Nov. 7, 1958 [Nov. 14, 1957], No. 35874/58. Class 122 (3). A starting device for a compressed-air operated free-piston engine comprises a differentialtype auxiliary piston 20, the maximum surface 24 of which is acted upon by line pressure thereby causing one or other of the smaller piston-ends 27, 28 to develop a greater pressure which is transmitted to the working faces of the main control piston 5 so as to move it into one or other of its end positions and thus enables the compressed-air to act upon the free-piston 2 of the engine irrespective of the position of the latter. In normal operation of the engine, compressed-air is fed via a manually-actuated inlet valve 12, through a conduit 3, chamber 13 of the main control piston 5 and pipe 14 to act upon the free-piston 2, causing it to move to the left and, in so doing, compressing air in a chamber 6 which, through a pipe 8 and non-return valves 46, 47, acts upon the end of the control piston 5 thereby reversing its position to that shown in dotted lines so that line pressure may then act, through pipe 17, to return the free-piston to the position shown. If, when the compressed-air is shut off, both the pistons 5 and 2 remain in these latter positions the engine cannot be restarted until the control piston 5 is moved to the position shown in full lines enabling line pressure to again act upon the piston 2 via pipe 14. This is effected by a valve 35, connected in the conduit 3 and urged by a spring 36, to the position shown, thereby admitting air through a pipe 38 to act upon the larger surface 24 of the auxiliary piston 20 thus causing it to force air, in a chamber 23, at a higher-than-line pressure through a pipe 32 and non-return valve 45 into a chamber 11 to act upon the small end of the control piston 5; if both the control piston 5 and free-piston 2 are stopped in the opposite end positions to that previously described, the valve 35 may be depressed by a lever 39, thereby producing the latter pressure-differential effect on the piston 5 via a pipe 40, chamber 22, pipe 30 and a non-return valve 45.
