Title: Improvements in or relating to hydraulic lifting devices for tractors
IPC: A01B63/111
Filed: 1963-11-08
Abstract: 1,069,462. Tractor power lift mechanisms. SAME SOCIETA ACCOMANDITA MOTORI ENDOTERMICI F. CASSANI & C. Nov. 8, 1963 [Nov. 9, 1962], No. 44235/63. Heading A1P. A tractor power-lift mechanism incorporating position control and draft control is characterized in that a lever can be moved to select one control whilst automatically rendering the other control inoperative. An implement is mounted on a tractor lift linkage, the lower links 5, see Fig. 1 (not shown), of which are pivoted to a spring-biased lever 7 whereby a draft control signal is communicated to a hydraulic control system through levers 23, 24 and 25. Draft control. The lever 21 is moved to the draft control position and the amount of draft is selected by lever 22. For this, lever 21 operates on rod 58 to move a threearmed lever 53 about a pivot 54 so that a roller 55 is moved out of engagement with a cam 56 on the rockshaft 40, and also so that a cam surface 79 on a lever 80 is moved into engagement with a roller 78 on a crank 75 which is thus moved until the other end of the crank, which is pivoted on a lever 71 of a linkage operated by hand lever 22 in order to move a control lever 59 arranged to move the control valve 43 of the hydraulic system, moves, together with lever 71, into engagement with a stop 66. Draft control signals transmitted through lever 25 to rod 62 pivot lever 59 about its end 68, thus pivoting lever 49 about its pivot 50 to operate the control valve whereby the lift linkage is moved to bring the force in the rod 62 and therefore the control valve back to an equilibrium position. Position control. The lever 21 is moved to a position whereby operating rod 57 moves the roller 55 on the three-armed lever 53 into engagement with the cam surface 56 on the rockshaft. The lever 80 moves away from the roller 78 on the crank 75 and the lever 71 thus moves clear of the stop 66. Movement of the hand lever 21 directly operates lever 49 through the three-armed lever 53 and thus the control valve. Equilibrium is restored in the new position by the cam surface 56 pivoting the threearmed lever about pivot 74 to move the lever 49 and control valve into the neutral position. Float position. The lever 21 is set intermediate the other two positions where the roller 55 is out of engagement with the cam surface 56 and also the lever 80 is not engaged by the roller 78. Under these conditions the control valve 43 is pushed by spring 46 into the exhaust position and no 'follow-up' movement can take place. A device for rotating the valve 45 every time the lever 21 is moved whereby sticking of the valve is prevented, is also incorporated. The rate of descent of the implement can be restricted by a valve as described in copending Application 42912/63. Springs 87, 88 absorb shock in the levers systems respectively of hand levers 21 and 22.

Filed: 1975-10-30
Abstract: 1511498 FDM switching THOMSON-CSF 30 Oct 1975 [31 Oct 1974] 45098/75 Heading H4K Channel switching in an FDM telephony system is effected using a switching unit-Fig. 1-having two branches, one for each direction of transmission. Each branch includes an input mixer, channel filter and output mixer, and the branches are interconnected as shown by programmable variable frequency generators 1 and 2. Each generator is capable of providing m discrete carrier signals, where m is the total number of channels (both incoming and outgoing) to be handled by the switching unit. Considering a group of FDM channels incident on the unit at 10, the input mixer 11 frequency translates them all and then the single side band filter 13 selects just one of these translated channels, which is then finally frequency translated in output mixer 12. By appropriate choice of the respective outputs of generators 1 and 2 any channel f 1  in the group incident at 10 may be switched to a channel f 2  which is output at 14. Similarly, for the same setting of the generators, channel f 2  contained in an FDM group incident at 20 is switched to channel f 1  at the output 24. Each circuit branch may be provided with means for extracting or inserting signalling information. A plurality of switching units may be combined in a switching frame, Fig. 2. As shown the frame contains 120 units and provides for switching between one FDM group of 120 channels (incoming on highway E, outgoing on highway S) and another FDM group of 120 channels (outgoing highway derived from multipling of outputs 14, incoming highway commoned to inputs 20). Fig. 3 shows two arrays of switching frames (B1-120 and b1-120) interconnected to form a switching centre. Correspondingly numbered units within the array of frames B1-120 have their respective outputs combined in couplers CD1-120 to form 120 "transitional" FDM groups each of 120 channels. These groups are distributed among the array of frames b1-120 in an analogous manner as shown. Couplers cd1-120 are provided for the return direction of transmission. All the generators 1, 2 have their control inputs connected to the central control of the switching centre. By selection of suitable frequencies for generators in two switching units, one in array B1-120, the other in array b1-120, the central control can set up a connection between any two FDM channels via an intermediate channel. Channel switching may also be effected using just one set of switching frames coupled to a main distribution frame, Figs. 4-8 (not shown).

Abstract: 1,236,213. Coiling slivers. SANT ANDREA NOVARA OFFICINE MECCANICHE E. FONDERIE S.p.A. 25 Sept., 1968 [27 Sept., 1967], No. 45586/68. Heading D1F. In a sliver-coiling apparatus a sliver-severing device periodically operable in response to each automatic can-change comprises a travelling arm, searching for the festoon of sliver between the delivery mechanism and a felled can, and a pair of severing rollers which exert a pull on a festoon located and fed thereto by the arm. After the can change, a drive screw 8 is rotated to shift a nut 7 so that an attached arm 4 leaves an inoperative position and makes its search movement transversely across the path of the cans. When a sliver 1 caught by the arm 4 is carried into a position between driven severing roller 5 and roller 6, an abutment 35 acts on part 34 of locking lever 29 to disengage tooth 31 from lever 24 and thereby cause rollers 5, 6, to snap together under the action of springs 27, so gripping the sliver therebetween and severing it by pulling, the piece between rolls 5, 6, and the departing can being expelled by the continued rotation for a short time of the rollers, and as nut 7, having operated an end-of-travel microswitch (44) engages a stop 15 to prevent rotation of screw 8 and travel of arm 4. The microswitch, effective after a predetermined delay e.g. one second, to permit rollers to expel the whole length of sliver remaining between rollers and the delivery device, reverses the drive to screw 8 whereby arm 4 returns to a locked inoperative position whilst nut 7 operates another microswitch (45) to stop the motor (21) drive to the device which is then ready for the next can-change operation. Before completing the return movement, nut 7 engages an abutment (41) so that rod 39 follows such movement and an abutment 40 engages eye 38 of a resetting lever 37 which pivots on pin 30 whereby end 38a depresses rod 42 and lever 24 which then rotates about pin 25 against loading spring 27 to force roller 6 downwards and apart from roller 5, the lever 24 being locked by reengagement of tooth 31 with recess 32.
