Title: Line pressure regulating system for automatic power transmission
IPC: F16H61/04
Filed: 1971-12-16
Abstract: 1337038 Change-speed control NISSAN MOTOR CO Ltd 16 Dec 1971 [18 Dec 1970] 58390/71 Heading F2D  A pressure regulator valve 51, controlling line pressure 55 in a four-speed and reverse automatic transmission on a motor vehicle, is loaded upwards, for pressure increase, by a spring 63, and downwards, for decrease, by line pressure 55, acting through a restrictor 65 on differential lands 58, 59, and is subject to further upward loading by a line 83, 72, which receives pressure through a ball-check 84 from whichever has the higher pressure of two lines, 105, throttle pressure, or 102, 101, modulator pressure, supplied by a modulator valve 52, subject to governor and throttle pressure loading 96, 97, and fed through a shuttle valve and line 99 with throttle pressure in D setting and line pressure in any other setting except N and R. The same modulator pressure 101 also acts downwards on the regulator valve 51 at 71, and further downward loading for pressure decrease is provided at 70 by line pressure supplied through a shift valve in fourth ratio position in D setting. This produces the following line pressure conditions. At low speeds in any selector setting the modulator line 101 is exhausted and line pressure 55 increases with throttle pressure 105, 83, 72 to its maximum values, (line a), Fig. 3, not shown. In D setting at higher speeds, if governor pressure 96 prevails over throttle pressure 97, the modulator valve 52 moves down and supplies throttle pressure to line 101 to act downwards on the regulator whilst the same pressure 105, 83, 72 still acts upwards, resulting in line pressure cut-back (line (b)), which is further cut-back (line c) by fourth ratio pressure supplied at 70. Selection of any manual setting 3, 2 or 1, at high speed from D, changes modulator pressure 101 from throttle to line, shifting the ball check 84 to substitute line for throttle pressure at 83, 72, thus providing a constant high line pressure independent of throttle (line d), for non-slip engine-braking at high speed. Gear arrangement.-Fig. 1 shows a torqueconverter - driven three - train sun - ring - planet gear, connected as shown, to give three reduced ratios, direct drive and one reverse. An input clutch 17 is engaged for all forward ratios; with brake 19 for first; 20 for second and 18 for third ratio; a second input clutch 16 being used for direct-drive, with the input clutch 17, and for reverse with the brake 19.

An electrical connection device comprises an insulating body having a conductor therein, with bores extending through the conductor and the body, each bore containing a conductive member arranged to receive and retain an electrical contact inserted in either end of the bore. In one embodiment (Figs. 3, 4), the insulating body comprises sections 11, 12 with a conductive strap plate 21 in a recess between them. Bores 16 extending through the housing and strap plate contain conductive retainer members 17, which have flared ends 24, 25 engaging shoulders 49, 50 in the housing so that the members 17 are held captive. Each member 17 comprises a sleeve having a longitudinal slot 23 therein, and is provided with inwardly bent tabs 26, 27 formed by making L-shaped cuts in the sleeve. Further pairs of inwardly bent tabs 40, 41 are provided nearer the midpoint of the sleeve, and opposite these are domeshaped protrusions 42, 43, beyond which are flared abutments 44, 45 which engage and make electrical connection with the strap plate 21. In use, each member 17 receives a pin contact 52, 53 at either or both ends. The pin contact 52 is crimped to a lead 54, and has an enlarged portion 57, the pin being inserted until the shoulder 60 is adjacent the dome 42, in which position the tab 26 snaps behind and engages the other shoulder 59, so that the contact may not move longitudinally in either direction. The tabs 40 firmly abut the section 58 of the pin, so ensuring good connection. In a modification (Figs. 8-12, not shown) tabs (83, 84) corresponding to tabs 26, 27 are formed by making U-shaped cuts in the sleeve, and the longitudinal slot (79) is provided with inwardly-projecting flanges (89, 90). Opposite the slot, parallel circumferential cuts are made on either side of the sleeve midpoint, and the intermediate sections (85, 86) are displaced inwardly, forming a stop for the insertion of pins (91, 92). The edges of the displaced portions are bevelled, and the flanges (89, 90) rounded, so as not to impede the forward part (98) of the pin contact (91). Further slots (80, 81) are provided to facilitate insertion of the conductive sleeve into the housing. In both embodiments, the pin contact may be removed with a conventional tubular extraction tool. The housings may form a module (Fig. 1, not shown) with a rib 13 and groove 14 to aid aligning in the mounting. The module may contain more than one strap plate so that conductive members in different bores may be connected in desired combinations. The conductive retainer members may be of beryllium copper.

Abstract: 1406805 Measuring linear dimensions electrically ROLLS ROYCE (1971) Ltd 1 Jan 1973 [31 Dec 1971] 60956/71 Heading G1N Apparatus for simultaneously measuring several dimensions of a component comprises a set of fixtures, one for each shape of component, mountable on a base, and a set of measuring probes, at least one for each dimension which engage the fixture and a workpiece mounted thereon. The probe readings, identity data as to the fixture, and the orientation of the component and whether a master or normal component is being measured are transmitted to a computer which contains the desired dimensions and which provides an output indicating whether a compound is within tolerance or, if not, which dimension(s) is incorrect. Supporting and measuring apparatus The fixture 10 and probes 13 are mounted on a support structure 12. The fixture 10 has holes 64A located over switches shown as + on the support structure 12 and these signal in binary code the identity of the fixture (61) and the number of probes (62). Each probe has a fixed section 13 which locates in a slot in fixture 10 and a movable section 19 which is biased towards and engages the component 11. The component rests on brackets 14 having a horizontal portion 16 and a vertical portion 17. The master component has a section which engages switch 44 and the ordinary component engages switch 45. For ovality measurements, the component can be moved through 90 degrees by lever 28, switches 49, 50 indicating which position is occupied. The fixture 10 and probes 13 are magnetically held to the support structure 12. Measurement and processing of signals Each probe comprises an A.C. fed induction bridge and the fixture is shaped so that the probes give zero output for a correctly sized component. The probe outputs are read off in turn by multiplexing unit 37, converted to a position output at 38, to a D.C. signal at 39 and to a digital signal in the A/D converter. Signals indicating angular position of the component are fed in at 52 or 53, whether the master or component is present at 46 or 47, the fixture number at 65 and the number of probes (as a check) at 66. Measurement is initiated by a push button which provides a signal at 67 and on indication to the operator to move the component to the first angular position closing switch 49. The signal at 67 enables AND gates via line 83 and transmits the information on lines 46, 47, 65 and 67 to shift register 86. This is then clocked out by pulses 69 on line 91 and is fed on line 93 to the computer. Other AND gates are then enabled by lines 106 to input the probe readings to shift register 86 and thence to the computer. The operator then receives a signal to move the component to its other angular position and the readings are repeated. The computer computes the algebraic sum of the master dimension, the master probe output and the component probe output, for each dimension.
