Title: Hydraulic Control System for Automatic Transmission.
IPC: F16H61/00
Filed: 1968-02-07
Abstract: 1,183,654. Change speed control. NISSAN JIDOSHA K.K. 7 Feb., 1968 [9 Feb., 1967; 14 Feb., 1967], No. 5999/68. Heading F2D. In an automatic control system for a planet change speed gear wherein line pressure 125 for operating ratio establishing clutches and brakes (4 ... 7) is controlled by a main pressure regulating valve 102 subject to throttle variable (TV) pressure modulation, the valve 102 is additionally loaded by TV pressure 140 supplied through a "cut-back" valve 200 to reduce line pressure when an output speed responsive governor pressure 130 acting on the "cut-back" valve 200 exceeds a predetermined value or a value responsive to TV pressure. As shown the governor pressure 130 acting on the " cutback " valve 200 opposes the bias of a spring 202 and when the governor pressure exceeds a predetermined value the spool 210 of the valve 200 moves left to supply TV pressure 131 through a line 146 to the regulator valve 102 which reduces line pressure. In Figs. 8 and 11 (not shown), the spool of the cut-back valve is biased right by a spring and TV pressure and when the governor pressure (130) exceeds both the spring and TV pressures the cut-back valve spool moves left to supply TV pressure to the regulator valve (102) which reduces line pressure. Fluid system components.-An engine driven pump (101) supplies pressure liquid to the regulator valve 102 which controls line pressure 125 and admission of regulated pressure to a torque converter (3). An engine manifold depression servo 142 controls a throttle valve 107 supplying TV pressure 131 to a TV boost valve 108, the cut-back valve 200 and a line pressure boost valve 103 which latter increases line pressure with increasing TV pressure. The land 312 of the boost valve 103 is larger than the land 301 of the regulator valve 102 so that when TV pressure acts on both lands, TV pressure modulation of the regulator valve 103 is retained. The TV boost valve 108 supplies boosted TV pressure 133 to 1-2 and 2-3 shift valves 105, 106. The valves 105, 106 are automatically shifted in response to opposing boosted TV pressure 133 and output speed responsive governor pressure 130 which latter is supplied by first and second governor valves (112, 113) rotating with the gear output shaft. A 2-3 timer valve 111 controls the rate of engagement of a direct drive clutch (4) and release of a second ratio brake (6) during a 2-3 upshift. A manual range selector valve 104 has Reverse (R), Neutral (N), Drive (D) and Low (L) positions. In the reverse (R) and Low (L) ranges pressure liquid is supplied through a line 128 to the regulator boost valve 103 to increase line pressure. In the low (L) range a 2-1 downshift is permitted but a 1-2 upshift is prevented by supplying additional loading pressure 135 to the 1-2 shift valve 105 in first ratio. A solenoid-operated "kickdown" valve 110 supplies additional downshift loading pressure 134 to both shift valves 105, 106 when the accelerator pedal is depressed beyond its normal range.

Title: Improved method and means for the treatment of metal tubes or bars by means of liquid
IPC: C23G3/04
Filed: 1944-04-03
Abstract: <PICT:0597213/III/1> <PICT:0597213/III/2> In the treatment of metal tubes or bars with a liquid, bundles of tubes or bars are accommodated in a plurality of vertical chambers known as wells, the depth and diameter of which are sufficient to accommodate the bundles &c. vertically and which are provided with means for transferring liquid from one chamber to another.  The bundles c are each mounted in a cage or like support 4, comprising a central perforated stem and being supported on a perforated tray 6 and provided with an upper retaining ring 7, the cage being lowered by a crane into the well a. A supporting spider 8 for this is secured to the underside of the tray 6 and rests on a perforated support 9 in the lower part of the well a and a series of wells a are mounted in a frame b, the lower parts of the wells being provided with valves e connected by pipes f to sediment chambers g and also valves h communicating with a pipe i having a valve j and leading to a sump k, and also connected to a pipe m leading to an acid supply tank R.  The upper end of each well is provided with an air tight cover q and near its upper end, and with a fluid inlet r having associated therewith values t, u, v, the valve t between the inlet r and a water supply pipe x and the valve v between the pipe r and a compressed air supply pipe y and the valve v between the pipes r and hot air supply pipe z. Each well a is also provided with an overflow pipe 2 controlled by a valve 3.  To subject the bundles to pickling and subsequent treatment the appropriate valves are manipulated to enable the first of the wells to be filled with water and a sufficient amount of sulphuric acid to produce the desired pickling solution and a vertical bundle c of bars on its support 4 is then lowered into each of the wells.  Steam is then admitted to the first well to raise the temperature of the solution the desired amount.  When the pickling has been completed the cover q is secured in position, the overflow and sediment valves closed and the appropriate valves opened to establish communication between this well and the second valve and to admit compressed air to the first well.  The pickling solution is thus transferred to the second well, the valves between this well and the first well being closed.  The cover of the first well is then opened as well as the overflow valve and the well filled with water to wash the pickled bundles therein. The solution is then transferred to the third well, the second well then being filled with water as before.  Hot air may be admitted to the wells containing the washed bars to dry them.  The treated bars may be transferred to an isolated well and coated with lubricant or soap solution or this treatment may be carried in the wells described above.

Abstract: 587,399. Valve generating circuits ; impedance networks. PATELHOLD PATENT VERWERTUNGS- & ELEKTROHOLDING AKT.-GES. April 7, 1944, No. 6572. Convention date, April 12, 1943. [Classes 40 (iii) and 40 (v)] Damping is reduced in a piezo-electric crystal composed of Rochelle salt by subjecting the crystal to a D.C. or A.C. voltage of such magnitude that the crystal is worked outside the range in which the polarization/voltage characteristic exhibits hysteresis. In a crystalcontrolled oscillator, Fig. 2, in which the reaction coupling is provided by the inter - electrode capacity 5, a D.C. voltage is applied at 4, 4 through chokes 3, 3, so as to produce a field of 900 v./cm. or more across a Rochellesalt crystal 1. The temperature is controlled at a value, between the Curie points, at which dielectric losses in the crystal are at a minimum. Similarly, voltage from batteries 4, 4, Fig. 3, may be applied to Rochelle-salt crystals 1, 1 in a filter. The D.C. voltage may be obtained by transforming and rectifying high-frequency oscillations and may be stabilized. The natural frequency of each crystal depends upon the D.C. voltage applied to it and also on the amplitude of the A.C. component. If the latter is used for tuning the crystal, the temperature may be near one, preferably the higher, of the Curie points, in, order that the frequency may change rapidly with changes of voltage. Alternatively, the frequency may be varied by varying the temperature, but it changes only slowly with temperature if the strength of the field applied to the crystal exceeds 1400 v./cm. or if the temperature is at a Curie point or at the minimum point between the Curie points,
