Title: Machine for depositing seeds and fertilizers
IPC: A01C5/06
Filed: 1971-04-19
Abstract: 1331713 Seed depositing machine AMAZONEN-WERKE H DREYER 19 April 1971 [7 March 1970] 22914/71 Heading AID A machine for depositing seeds and fertilizer comprises coulters 11 which pivot about bearings 9 on supporting levers 10. Material from a container 2 passes through adjustable openings 23, proportioning device 24 and pipelines 25 into passages 26 which are rigidly connected to the coulters 11 by holders 28 carrying pivoted supports 29. Each pivoted support 29 has upper and lower skids 37, 31. The coulters 11 may be raised by levers 12 when the machine is to be used to spread material on the ground surface, the upper skid 37 then effecting spreading. In the lowered position, when being pulled by a tractor, the supports 29 pivot to a rearward position (29'), Fig. 3 (not shown). The coulters 11 then draw furrows which the front edges of the upper skids 3 cover after the seeds or fertilizer has been deposited. Coulter tips 35 act as a forward stop to the skids 31, 37, an upturned lip 46 similarly acting as a rearward stop. The support 29 pivot about an axis 30 on bolts which ride in downwardly and rearwardly extending slots thereby reducing the possibility of damage during coulter lowering and drilling.

Title: Improvements in or relating to rotary wing aircraft
IPC: B64C27/18
Filed: 1949-09-07
Abstract: 673,870. Rotary-wing aircraft. FAIREY AVIATION CO., Ltd., BENNETT, J. A. J., and FORSYTH, A. G. Oct. 18, 1950 [Sept. 7, 1949], No. 23199/49. Class 4 A rotary wing aircraft provided with reaction jet means for driving the sustaining rotor has two or more rotary compressors arranged to feed a common source of supply of compressed air constituting the working fluid for the jet means, gas turbine units being connected respectively to the compressors to drive them, and has at least one propeller, one of the power units driving that propeller. In the embodiment, shown in Fig. 4, stub wings 13, 14 carry turbines 17 which drive compressors 18 and propellers 19. Air is taken from the compressor via valves 24 and pipes 23 to a distributor 21 and thence through ducts 20 to driving jet units mounted on rotor blades 11. In a further embodiment, shown in Fig. 5, an additional turbine drives a compressor 27 which also supplies air, through a duct 28, to the distributer 21. A non-return valve 25 at the entry of each duct 23, 28 to the distributer ensures that should one air supply fail the rotor may still operate. Fig. 8 illustrates the control system for the embodiment shown in Fig. 5. The throttles 39. 40 of theoutboard turbines 16, 15 are operated, through differential units 41, 42, by means of hand levers 43, 44 or by means of a foot-bar 47 pivotally mounted at 48. The air valves 24 are connected by a link 49 and are operated by a hand lever 50. A hand lever 53 controls the throttle 51 of the turbine 26 independently of the other controls. The differential unit 42 comprises crown wheels 57, 59, Figs. 11 and 16, connected by arms 56, 58 and links 55, 46, respectively to the throttle lever 44 and the footbar 47. The crown wheels 57, 59 are engaged by pinions 61, 62 mounted on a carrier 60 which is connected by a lug 63 thereon and a linkage 64 to the throttle 40. The control levers 50, 43 and 44 are operatively interconnected by means of a gate 65 and a gating bar 66 whereby when changing from hovering to forward flight the lever 50, in being moved to cut off the air supply to the rotor (which then anti-rotates), simultaneously reduces the power to that required by the propellers for forward flight. By differential control of the thrust of the two propellers, the aircraft may be controlled in yaw. The differential control may be applied to the pitch of the propellers or to the engine throttles as shown.

Title: Improvements in or relating to the securing together of parts of shoes by adhesive
IPC: A43B13/32
Filed: 1932-08-19
Abstract: 406,030. Boots &c. BOSTON BLACKING CO., Ltd., 88, Brunswick Street, Leicester.-(Assignees of Wedger, W. H. ; Belmont, Massachusetts, U.S.A.) Aug. 19, 1932, No. 23231. Convention date, Dec. 29, 1931. Addition to 399,525. [Class 17 (ii).] Relates to the methods claimed in the parent Specification of forming adhesive joints between shoe parts by coating a part or parts with a cellulose compound cement, allowing the cement to dry, and softening it before use by means of a softening composition including a highly-volatile solvent and a material, e.g. a nitrocellulose, of high viscosity, and consists (a), in using a softening composition of such viscosity that it will not flow or spread when applied to the cemented part, and (b), in applying the composition to a portion of the cemented part slightly smaller than the whole cemented area. As applied to the sticking-on of soles, a marginal portion 10, Fig. 2, is coated with cement. Softening composition is then applied only over the strip 12, leaving a marginal strip 16 of cement unsoftened. When pressure is now applied to the sole, a slight flowing of the softening medium and/or cement occurs, sufficient to activate the cement as far as the outer edge of the area over which attachment of the sole to the upper is desired, but insufficient to cause staining of the upper by extruded cement. A suitable softening composition comprises 40 grams on the dry basis of nitrocellulose of 1100-seconds viscosity, 18 ccs. of denatured alcohol, and 900 ccs. of acetone. Such a composition is stated to allow ample time for the assembly of the shoe parts before pressing, yet to set sufficiently to allow the shoe to be removed from the press after approximately one or two minutes. The desired viscosity of the composition may be obtained by employing larger quantities of a lower viscosity cellulose derivative, but the solid content of the composition should be kept as low as possible. Instead of acetone, ether or ethyl acetate may be used, and a plasticiser, such as dibutyl phthalate, or a diluent, such as pentane, may be added. Specifications 363,623 ; and 395,767, [Group III], are referred to.

Filed: 1926-09-22
Abstract: 282,854. Mix & Genest Akt.-Ges., and Lohaus, O. Sept. 22, 1926. Thermionic valve circuits. - Comprises an arrangement for causing a transient electric impulse to affect a relay for a substantial period of time. The apparatus may be connected to the line 4, in which the transient impulses are to be detected, by two condensers 3, 9 arranged as shown in Fig. 1. The condenser 3 is connected to the grid 1 which has a condenser 13 and leak resistance 12 and is earthed through a variable condenser 5 and resistance 7, while the condenser 9 is earthed through a condenser c and is connected to the filament 8. An additional grid g is coupled to the tuned circuit of a relay 11. The impedances are so adjusted that the normal A.C. in the line 4 does not effect a signal, but transient impulses cause a blocking charge to accumulate on the grid 1, and the resulting fall in output current operates the relay 11. In a simplification, Fig. 2 (not shown), the condensers c, 9, conductors 18 and grid g are discarded, the filament 8 is earthed, and the grid leak and condenser are connected between the grid 1 and conductor l. In a push-pull arrangement, Fig. 3, the line 4 is earthed through a coil 16 and a transformer t whereof the primary consists of the lead l and the secondary of a ring coil 17 whose middle point is earthed. In a modification, Fig. 4 (not shown), of the arrangement shown in Fig. 3 a single valve is used. Reference has been directed by the Comptroller to Specification 245,176.

[Class 4] In a cyclogyro which includes a port and a starboard rotor each of the type comprising a rotatable vane carrier having mounted thereon a plurality of vanes distributed around the rotor axis and movable respectively about axes parallel or nearly parallel to the rotor axis, the vanes being drivably connected to the carrier by gearing which constrains them, during rotation of the rotor, to move in such manner and with such phase displacement relative to each other that, when the rotor is rotated and at the same time translated, relatively to the air, normally to its axis at a speed equal to the peripheral speed of the vane axes, each vane is maintained, during the whole or substantially the whole of its orbit, at a constant or substantially constant angle of attack to the resultant air-stream, the gearing includes an adjustable element for varying the phase of the vanes, the phases of the rotors being adjustable differentially and the rotors are capable of rotation independently of each other under the influence of the air-stream due to translation of the aircraft. The rotors may be driven through free-wheel clutches and the translation may be that obtaining in gliding flight or be due e.g. to the power derived from an airscrew. Two rotors may be employed in which case usual tail surfaces are provided, alternatively these surfaces may be replaced by two further rotors. As shown, the carrier comprises end rings 20, 21 joined by tubular members 22 on which the vanes rotate. The ring 20 is integral with a disc 20<1> fixed to a hollow driving shaft 25. The vanes are controlled through a planetary bevel or spur gearing from a shaft 27 and comprising a carrier 29 connected by an eccentric pin 31 to an eccentric disc 32 engaging eccentrices 33 fixed on the vanes. The ring 20 is engaged by rollers 36, 37 journalled in brackets secured to the fuselage. The members 22 may carry the vanes in which case the members are journalled in the ring and turn on spigots carried by the ring 21 and the drive is transmitted through a shaft concentric and within the shaft 27. When four rotors are employed these may be driven from prime-movers 70 through a clutch 79 operable to give a direct or reduced drive, a shaft 50, bevel gears, 68, 67, differential gear D, shafts 50s, 50p, bevel wheels 63p, 62, 63s and shafts 58a, 58f including differential gears Dp, Ds and provided with brakes 52 which may be differentially controlled. The phase adjustment of the rotors may be controlled from a universally mounted joystick through cables which may be operated for simultaneous control of all the rotors. The cables may be further controlled by an automatic pilot. The vanes may be of reflex curvature and have a symmetrical cross-section and they may be governed by crank-arms guided in a cam ring.
