Abstract: 1368282 Axial-flow fans DEFENCE SECRETARY OF STATE FOR 15 May 1972 [15 May 1971] 15187/71 Heading F1C In a bladed rotor having a pitch changing mechanism and means for selectively operating the mechanism and wherein, in operation, the blades are each subject to a centrifugal turning moment, mass elements are supported for rotation about the rotor axis for producing centrifugally a torque about the axis and are connected to the pitch changing mechanism so that operation of the mechanism causes a movement of the elements to vary the torque produced by the elements to correspond to the change in centrifugal turning moment on the blades in their new position, this torque being applied to the pitch changing mechanism in such manner as to oppose (and preferably slightly exceed) the torque applied by the blades due to their centrifugal turning moment. Fan blades 11 are varied in pitch by means of oppositely rotatable crown wheels 18, 19 meshing with a bevel gear 16 attached to each blade. The crown wheels are actuable by a vane motor 17 having oppositely rotatable inner and outer casings 21, 22 connected to the crown wheels. The casings 21, 22 are also connected to coaxial annular gears 23, 24 which mesh with planet gears 25 supported by a planet carrier 26. Counterweights 28 connected to the planet gears 25 produce centrifugally a torque during operation of the fan to overcome the inherent centrifugal moment tending to turn each blade 11 into the fine pitch position.

[Also in Divisions G1, G2 and G4] A navigational device for use in aircraft comprises a sequence of maps 1 in transparency form on a film 2 which is so movable in directions parallel to and perpendicular to its length by motors ME and MN which are actuated in accordance with the velocity, angle of track and angle of convergence of the meridian at the position of the aircraft with which the device is used that the position of the aircraft is indicated by a fixed mark on a screen on which an image of the appropriate one of the map transparencies is projected. The film which is provided with maps based on conical projections (Fig. 3, not shown) and which is supported on rollers 3 and 4 so that one map is projected through a window 17 in a support 5 to the screen, is longitudinally positioned between the rollers 3 and 4 by the motor ME which acts through a differential gear 15 to drive a sprocket roller 14 and is vertically positioned by the motor MN which actuates a screw-threaded rod 10 connected to lugs 8 and 9 of the support 5. Signals which drive the motors MN and ME to move the film so that the fixed mark indicates on the image of the projected map the position of the aircraft are derived from a navigational computer which provides an output in accordance with the actual velocity and track of the aircraft. Corrections are made to allow for the angle of convergence of the meridians of the projected map and hence for changes in track angle relative to the sides of the map by providing a convergency unit (33) (Figs. 4 and 5, not shown). The signals representing the corrected angle of track and the movement of the aircraft relative to the map are fed to a resolver 35 and thence to integrators and followup units to provide signals which suitably drive the motors MN and ME. Further motors may be provided respectively to move the film so as to change from one projected map to another and to rotate the image of the projected map on the screen.

Title: Improvements in automatic conveyors
Inventor: KLOOSS SIEGFRIED
IPC: B65G47/48
Filed: 1960-05-02
Abstract: 905,185. Endless conveyers which automatically distribute work to predetermined stations. SCHUH - UND SATTLERMASCHINENBAU LEIPZIG VEB. May 2, 1960, No. 15371/60. Classes 78 (1) and 104 (2). Carriers 9 (Fig. 11) are propelled horizontally by endless chain 2, the engagement being made by chain pins 3, 4 which slot into carrier elements 13, 14 and are thus distributed to working stations in accordance with the manual setting of keys 69 mounted on the carrier. Selected working station (Fig. 5). The engagement of the keys 69 of a carrier with electrical contacts at that station effects momentary energization of solenoid 21. This causes segment 44 to be lowered, which allows pin 41 to spring into engagement with wheel 36, to thus couple member 38 to said wheel 36; and, since member 36 is constantly rotating because it is driven from chain 2, shaft 33 rotates to drive endless elevator 100. The latter therefore, as it rises, causes a carrier bar 19 to hook under notch 75 (Fig. 11) of the carrier, and lifts the carrier upwards till a projection on the elevator frees segment 44 and allows a spring to return it into engagement with pin 41. The latter therefore is withdrawn to the right. This disconnects the elevator from rotating wheel 36 and the carrier is held stationary by pawl 58 in the upper receiving position 15 of elevator 100. The carrier is then displaced leftwards by engagement of a gear-wheel with toothed rail 84 (Fig. 11) mounted on the carrier. The carrier is now in its despatch position 16 being supported by rail 23 of endless elevator 101, and the operator now processes the goods carried by the carrier. When he has finished he presses a button to energize solenoid 25. This operates in a similar way to solenoid 21 and, when an empty pair of chain pins 3, 4 is available causes the elevator and therefore the carrier to descend and the carrier to lower itself on to the chain 2 to be conveyed further.
