Title: Improvements in or relating to servo-systems
IPC: G05D1/08
Filed: 1959-08-14
Abstract: 932,599. Automatic control. MINNEAPOLIS-HONEYWELL REGULATOR CO. Aug. 14, 1959 [Aug. 18, 1958], No. 27903/59. Class 38 (4). In a servo-system for controlling a variable, a servomotor is controlled by a signal dependent on the difference between a signal representing a mathematical derivative of changes of the variable and a control signal, representing a desired response of the variable, derived through a simulator having a response corresponding to the desired response of the controlled and controlling system. In Fig. 2 a D.C. signal from a controller 22 may be produced by a manually-operated potentiometer (not shown) or the pitch pick-off of a gyrovertical 23 according to the setting of switches (not shown), and applied to an amplifier 49 having resistance-capacity feedback to produce a second order response simulating that of the system to be controlled. Any difference between the D.C. output signal from amplifier 49, representing the desired rate of pitch, and the amplified D.C. signal from a gyro 11, detecting actual rate of pitch, is applied through a resistance-capacity circuit 64 and an amplifier 68 to electronic amplifier-limiter 75. In addition to the D.C. error signal, a constant A.C. signal from an oscillator 100 is also applied to amplifier-limiter 75 so that its output/input characteristic is similar to that shown but varies slightly according to whether the oscillator waveform is sinusoidal, triangular or rectangular. Further limitation is imposed by a diode circuit 78 which is controlled in dependence on the magnitude of the error signal by a gain changer 150 so that the limits are narrower for smaller errors. In a modification gain changer 150 is arranged to vary the limits progressively according to the magnitude of the error so that a suitable characteristic is obtained without the need for oscillator 100. A further biased diode circuit 106 is provided so that only error signals exceeding a predetermined minimum magnitude are passed on through an adjustable filter 117, modulator 126 and servoamplifier 128 to a two-phase torque motor 130 operating the elevators through an hydraulic servo-system 119. Positional feedback from a potentiometer operated by the elevators is fed through a high pass filter to the input of modulator 126. Controller 22 includes a potentiometer which may be manually adjusted to apply to amplifier limiter 75 a signal which cancels any undesired signal. Suitable thermionic valve amplifiers with cathode followers are described.

Title: Turbo coupling
IPC: F16D33/00
Filed: 1962-07-20
Abstract: 990,398. Hydraulic couplings. C. SCHULERVOITH, M. VOITH, H. W. SCHWEPPENHAUSER, and C. KNAPP, (trading as VOITH GETRIEBE KOMM.-GES). July 20, 1962 [July 22, 1961], No. 28035/62. Heading F2C. To obtain progressive change in torque between the driving and driven shafts of an hydraulic coupling when changing from the high slip to the low slip condition and vice versa, an hydraulic accumulator is formed within the coupling and substantially within the space inside the impeller blades, a perforated or similar liquid flow partition being provided between the accumulator and the coupling working space to obstruct the vortex flow in the working space under high slip, lowspeed working conditions. In one form, an impeller 41, Fig. 4, is formed with a partition 45 defining an accumulator 44, and a turbine 42 carries a baffle 46 having circular rows of holes 47-49 therein. During low slip, highspeed working, centrifugal force keeps the liquid in the coupling in radially outer positions. As low speed, high slip working is approached, the liquid tends to flow radially inwards, some at first passing through the outer row of holes 47 in the baffle 46 into the accumulator 44. With further decreasing speed &c., more and more liquid passes through the baffle holes 47-49 into the accumulator 44. A progressive change in the transmitted torque is thus obtained. When proceeding from high slip, low speed working conditions to low slip, high speed conditions, the accumulator 44 is at first partly filled with liquid but finishes empty. In one modification, Fig. 6 (not shown), a shutter moves radially over the holes 47-49, against spring bias, with increasing speed and centrifugal force. In another modification, an accumulator 63, Fig. 7, within an impeller 61, has liquid directed into it by a partition 62 integral with the impeller and formed with holes 67. In further modifications, Figs. 8, 9 (also not shown), the accumulator &c. is formed from sheet metal parts. An additional baffle in the shape of a ring within the working space may be provided. In yet another modification, flow control is provided by slots between fingers on a radial flange around the outer wall of an accumulator, Figs. 10, 11 (also not shown). A fluid coupling of known form having a central container but no baffle is illustrated in Figs. 1, 2 (not shown). A graph of slip plotted against torque for various arrangements is illustrated in Fig. 3 (not shown). Reference has been directed by the Comptroller to Specification 692,286.

Abstract: 482,456. Stamping-press. TONKS, R. G. Oct. 17, 1936, No. 28273. [Class 83 (iv)] In cupping - presses a greater depth of draw is obtained than is usual with a giver stroke of the pressure member. Part of the force exerted on said member is transmittec to and absorbed by a fluid for transferring it to a complementary tool or tools for performing additional work As shown in the Figure a hydraulic press utilizing two rams has an annular draw plate 3 with depending ports 4 resting on an annular ram 5 in a cylinder 6. A ram 8 with a too] 8a is arranged in the annular ram 5. A block 8b integral with the ram 8 is attached to a rod 9 which bears against a spring 10. Annular spaces 6a, 6b in the cylinder are in communication. The ram 5 rests on spring pressed pins 12. A non-return ball valve 18 controls a passage 6c leading to the cylinder 6 and may be automatically lifted. The ram may be positively returned. When pressure is exerted by the tool 15 the draw plate 3, posts 4, and annular ram 5 move downwards forcing fluid from the space 6a into the space 6b exerting pressure on the block 8b to move the tool 8a upwardly against the action of the spring 10. The latter restores the ram 8 to its initial position when the pressure is removed and a spring 14 restores the annular ram.
