Title: System for monitoring and controlling a redundant electrohydraulic positioning drive
IPC: G05D1/00
Filed: 1974-04-09
Abstract: 1459516 Fluid-pressure servomotor systems VEREINIGTE FLUGTECHNISCHE WERKEFOKKER GmbH 9 April 1974 [9 April 1973] 15665/74 Heading G3P A system for controlling a redundant electrohydraulic positioning drive comprising at least three working cylinders acting on a common load includes at least as many pressure dependent signal transmitters as the number of working cylinders, each transmitter being connected to the working chambers of at least one cylinder, and a common comparator to receive the signals and acting to switch-off a faulty cylinder. In one arrangement, four working cylinders 10 to 13 have a common piston-rod 18 connected to control nozzles 41 and surfaces 44 of a VTOL aircraft. Each cylinder 10 to 13 is connected to a respective servovalve 19 to 22 which is supplied by an individual hydraulic system via a shut-off valve 23 to 26. Four signal transmitters 27 to 30 are provided, each having an auxiliary cylinder 31 with a potentiometer 32 displaceable thereby. The working spaces of each auxiliary cylinder 31 are connected to the working spaces of two adjacent working cylinders 10 to 13. The signals generated by potentiometers 32 are fed to an error logic unit 35 which, in the case of minor deviations, transmits signals to scanning amplifiers 36 to 39 controlling servovalves 19 to 22. The amplifiers also receive primary input signals together with positional feedback signals from potentiometers 40. In the case of a major fault in a working cylinder 10 to 13, logic unit 35 transmits a signal to the appropriate valve 23 to 26 to cutoff the hydraulic supply to the faulty cylinder. In a modification Fig. 3 (not shown), the auxiliary cylinders 31 and potentiometers 32 are replaced by capsules (56 to 59) which generate electric signals corresponding to the applied pressure. Each capsule is connected to the working spaces of only one working cylinder 10 to 13 and a comparison of the signals from all the capsules is made in the logic unit 35. In a further modification Fig. 4 (not shown) the system includes two additional signal transmitters (60, 61) which provide diagonal monitoring paths.

Title: Improvements relating to rotary, demountable jib cranes
IPC: B66C23/26
Filed: 1935-06-01
Abstract: 445,157. Jib cranes; turntables. BESNARD, F., 17, Rue du Sergent Bauchat, Paris. June 1, 1935, No. 15986. Convention date, June 4, 1934. [Classes 78 (iv) and 104 (ii)] Rotary demountable jib cranes of the kind in which a jib is carried by a turntable and is supported by bracing members under tension anchored to the turntable on opposite sides of the fixed vertical pivot of the turntable, and also in which the weight of the loaded jib is taken by a single wheel running on the turntable adjacent the foot of the jib, are modified by (1) providing a wheel diametrically opposite to the single wheel which only engages the turntable when the crane is unloaded, (2) by replacing or supplementing the single wheel by a pair of wheels arranged near to but not in exact alignment with the foot of the jib, and (3) by providing symmetricallyplaced lateral rollers at right angles to the load-carrying wheel to prevent excessive lateral rocking due to variation in the run-off of the winding rope from its drum. In one construction shown in Fig. 2, the jib is pivoted to one end of the turntable 6 rotating on the ball-bearing sleeve 36 about a central fixed pivot, and the weight is supported by the peripheral wheel 4. The second wheel 39 is diametrically opposed to the wheel 4 so as to be free of the track normally, but to engage it when the crane is unloaded and thus prevent undue strain on the turntable pivot. Two other rollers arranged at right angles to the first pair may be fitted to take up strain on the pin caused by the varying position of the winding rope on the drum, and to form pivots on which the table rocks in moving between the loaded and unloaded positions. The roller 4 may be supplemented by, or be replaced by, two other rollers 40, Fig. 13, symmetrically placed on either side of it. When supplemented in this manner, the roller 4 may be driven positively by chain and worm gear 41, 42 to effect the slueing. These rollers 40 mav in some cases act as substitutes for the rollers at right angles to the load wheel. The structure may be provided with screw jacks which are lowered into ground-engaging positions when the crane is in use.

Abstract: 118,366. Keckritz, A. R. Nov. 2, 1917. Ploughs.-The depth of working of a plough is controlled automatically by the draught necessary to pull the plough. In. the plough shown in Figs. 1 and 2, the draught bar 4 is adjustably connected to a lever 12 pivoted at 15 to the main frame and secured at its other end to an adjustable spring 19. The lever 12 is also connected by a chain 27, the length of which can be varied, to an arm 26 on a cranked axle 5 carrying the furrow wheel 2. Should the draught increase, the lever 12 is drawn forwards against the tension of the spring 19 and the arm 26 is pulled over, forcing the furrow wheel downwards and lifting the ploughs 1. The arm 26 is connected through an adjustable lost-motion connexion with a similar arm 30 extending from the cranked axle carrying the land wheel 3, and the arm 30 may in its turn be connected to a lever carrying a rear wheel 9, so that in cases of considerable increase in draught the wheels 3 and 9 are operated in addition to the wheel 2. In the modified form suitable for draught animals shown in Fig. 7, the ploughs are raised and lowered by the hand-lever 48 operating the bell-crank lever 50, 52 through the slotted link 56. The bell-crank lever is connected by another link to a vertical rod carrying the wheel 45. On the draught increasing, the adjustable lever 12<c> is moved against the tension of the spring 19<b>, operating the bell-crank lever 50, 52 through the link 27<a>, the slot 56 in the link 49 permitting this movement. In other modifications, friction rollers are provided for the draught bar, and the lever 12 and the tension spring is placed in another position.
