Title: Hydraulic control system for an automatic transmission
IPC: F16H61/02
Filed: 1976-03-16
Abstract: 1488636 Change-speed control AUTOMOBILWERK EISENACH VEB 16 March 1976 [26 March 1975] 10437/76 Heading F2D In an automatic transmission providing at least three forward ratios established by fluid operated brakes B1, B 2  and clutches K 1 , K 2  controlled by a 1-2 shift valve 20 and a 2-3 shift valve 30, and in which the shaft valves are actuated by the difference between an engine loading dependent pressure P D  effective in conduits 50, 51 and a vehicle-speed responsive pressure P v  determined by a centrifugal governor valve 2 and effective on pistons 201, 301 of the shift valves, a selector slide 1 is positionable at one setting in which it interrupts the supply of fluid to the centrifugal valve to hold low ratio, and at another setting in which it enables fluid pressure to actuate a blocking valve 41 to allow the pressure P v  to act on the 2-3 shift valve piston 301. The figure shows the selector 1 set for automatic operation in all three ratios and the shift valves positioned to establish low ratio. Fluid at a main pressure P H  generated by an engine driven pump and regulated by a valve (not shown) in dependence on engine output and vehicle motion is delivered to a passage 16 feeding a hydrodynamic torque converter and a lubrication circuit, to a passage 15 leading to a clutch K 1  to establish low ratio, to a passage 12 supplying the centrifugal valve 2 which supplies the pressure P v  through a conduit 21 to the piston 201 and through a conduit 22 and the valve 41 to the piston 301, and to a passage 11 for holding the valve 41 in the position shown against the bias of a spring 42. Leftward displacement of the shift valve 20 in response to increasing P v  pressure establishes second ratio by engaging the brake B 1 , in addition to the clutch K 1 , and leftward displacement of the shift valve 30 in response to further increase in P v  causes B 1  to be exhausted and K 2  to be pressurized, in addition to K 1 , to establish high ratio. Leftward displacement of the selector 1 to a position in which the communication between 10 and 11 is interrupted but that between 10 and 12 is maintained allows P v  to control automatic shifts between first and second ratios but causes the valve 41 to interrupt the application of P v  to the piston 301 and so prevent establishment of high ratio. If, however, high ratio is already established, downshift to second will be delayed until P v  acting on the end surface 412 of the valve 41 has fallen to a value at which is it overcome by the spring 42. Further leftward movement of the selector 1 stops the supply of fluid to the passage 12 and centrifugal valve to cause low ratio to be established and held, and energizes the brakes B 2  through a conduit 14 to provide engine braking. In a modification, an additional valve is provided to prevent enforced establishment of low ratio until road speed has fallen to a safe value.

The supply to a motor 1, e.g. driving a screwdriver or watch-winding apparatus, is interrupted at 3 at a predetermined torque and restored after a predetermined time, sufficient to allow repositioning of the tool. The contacts 3 are actuated by an electromagnet 15 connected to a monostable multivibrator. As shown, when the voltage across potential divider 4, 5 is sufficient, transistor 9 cuts off and switches on transistor 14 to energize 15 and open contacts 3; the circuit resumes its stable state after a delay determined by R.C. network 12, 18 and 13. A filter network 6, 7, 8 prevents maloperation by transients but in Fig. 2 (not shown), better discrimination is obtained by interposing a relay, switched by the potential drop across 4, 5 via a transistor amplifier and choke, which reverses the potential applied to the monostable circuit of Fig. 1.

Abstract: 638,635. Making and breaking screwed joints. EDELBERG, V. April 22, 1947, No. 10774. Convention date, June 28, 1946. [Class 83 (iii)] In screwing and unscrewing tongs for drill rods &c., having two superimposed annular members 5, 6 surrounding the two parts of the joint and connected together by means which drive them in opposite directions, a set of jaws 9 is articulated on each of the annular members, means are provided for tightening the jaws on to the two parts of the joint and for transmitting to the jaws the drive imparted to the annular members, and means are provided for varying the spacing between the annular members according to the height of the thread of the joint. The driving device may be separate from, or carried by, the tongs. In the form shown, the tongs rotate on a plate 1 which is carried from the substructure of the rotary table by means of fluid-pressure pistons 3 which allow for adjustment as to height. The pulley rings 5, 6 are freely rotatable on a median body 4 formed by two hollowed plates 16, 17 joined by springs 24, 25 and rods and sockets 26, 27 which allow separation of the plates 16, 17 according to the height of the thread of the joint. Each ring 5, 6 has pivots 7 for arms 8 ending in spring-centred pivoted jaws 9 which grip the tube 10, the arms 8 being operated by links 19 pivoted at 18 on controlling members 12, 13 carrying circular casings 14, 15 engaging the rings 5, 6 and the plates 16, 17. Slight rotation of the members 12, 13 in opposite directions by means of spring-set handles 21 brings the two sets of jaws 9 into wedging and driving engagement with the two ends of the tube 10. The rings 5, 6 are connected by an endless cable 36 with a turn-buckle for taking up slack, and by an ordinary anchored cable 35, respectively, to upper and lower drums driven by an electric motor, on the same platform as the tongs, through a differential so as to develop the same circumferential pull. When the motor is first started, the cable 35 is stretched and tightens the ring 6 on the tube 10. By progressively stretching the loose part of the cable 36 the ring 5 is rotated in the opposite direction to the ring 6, and the torque on the two rings 5, 6 increases equally until the joint is broken. Rapid unscrewing then follows under reduced torque. In a modified form, the tongs carry three groups of double electric motors, and' separation of the rings 5, 6 is effected by a double circular cam between them.
