Patent GB-1290840-A (GB)
IPC: G01M7/00
Filed: 1970-05-22
Abstract: 1290840 Testing turbine blades MITSUBISHI JUKOGYO K K 22 May 1970 [24 May 1969] 25022/70 Heading G1S [Also in Division H4] An apparatus for applying a vibration force to a stationary rotary body, particularly a gas or steam turbine wheel, comprises numbers of flipflops arranged in a ring circuit which direct the force to successive portions e.g. blades of the wheel. The vibration force is normally of more than one fundamental frequency and the amplitudes may be unequal and phase displaced. The number of flip-flops must be equal to the number of portions i.e. blades and the vibrations may be generated by a Piezo-crystal at each location. In a simplified arrangement for a turbine wheel having one nozzle and six blades each having one vibration force applied thereto, flip-flops F1-6 are connected in a ring circuit, F1 only having a direct set terminal Fc<SP>1</SP>. All reset terminals are connected to point D. A signal on Fc<SP>1</SP> causes Fl to set and energize Piezo-electric element P1. Elements P2 &c. are energized in turn by shift pulses fs1 applied to terminal S<SP>11</SP> which resets F1 and sets F2 et seq. The frequency of the shift pulses should be equal to the normal rotational speed of the wheel. If there is more than one nozzle the circuit must be rearranged so that P1 and P4, P3 and P5 &c. are energized in parallel. In a multi-nozzle turbine where groups of nozzles are selectively operated in parallel, a second vibration force of the same or different amplitude is selectively added to the first to reproduce working conditions which is arranged through gates (G1 &c.) Fig. 10 (not shown). In modification the flip-flops may be arranged so that pulse width outputs may be increased and the vibration forces may be superimposed non- coincidentally.

The fibres may be staple or continuous and may all be flame-resistant. The core may be of glass, regenerated cellulose or acrylic fibres which have been textured e.g. by subjection to a turbulent fluid stream, and the sheath fibres of an acetone-soluble copolymer of acrylonitrile and vinylidene chloride and/or vinyl chloride. The core may be twisted and/or in the final form of the yarn be twistless according to the required openness of the loops, sheath and core components may be differently coloured and the composite yarn may be doubled, prior to hot relaxing, with a balancing twist.

Abstract: 1347310 Transistor amplifying and pulseforming circuits NATIONAL RESEARCH  DEVELOPMENT CORP 29 Sept 1972 [18 Oct 1971] 48379/71 Heading H3T [Also in Division G1] A chopper-type amplifier has input and out-  put reversing switches, between which are connected, in cascade, an integrator comprising a first amplifier with a feedback capacitor con-  nected between its input and output and a differentiator comprising a second amplifier with a capacitor connected in series with its input, and a resistor connected between its input and output. As described the circuit is employed in a photometer, Fig. 2 (not shown), the input being derived from a solar cell and the output being fed to a meter. The two switches comprise bridges of four FET's, which may be in opposite conductivity pairs. In order to change the time constant of the integrator, Fig. 3 (not shown), one of a number of feedback capacitors (C4 ... C9) may be connected in the feedback path by means of a switch (S1). The differentiator, Fig. 4 (not shown), includes a switch (S2) for shorting out a part of the feedback resistor (R3, R4) to change sensitivity, and also Zener diodes D2, D3 to give overload protection. Switching signals for the two switches are derived from the mains supply by a frequency doubler, Fig. 5 (not shown), which comprises a full wave rectifier (S) and a phase splitter (T10, T11, T12). The balanced sinusoidal output from the frequency doubler is applied to E, F of a driver unit, Fig. 6, which comprises four pairs of transistors. During one half cycle, T16, T14, T17, T19 switch on, while T13, T15, T18, T20 remain off so that output terminal A is at -7 v. and terminal B is at 0. During the other half cycle the conditions reverse. The resulting output is a trapezoidal waveform whose leading and trailing edges have a slope derived from that of the input sinusoidal waveform at the zero crossings.

Title: Collarless circularly magnetized torque transducer having two phase shaft and method for measuring torque using same
IPC: G01L3/10
Filed: 1998-10-21
Abstract: A magnetoelastic torque sensor for providing an output signal indicative of the torque applied to a member about an axially extending axis of the member, comprising, a first magnetoelastically active region in the member, the region being magnetically polarized in a single circumferential direction and possessing sufficient magnetic anisotropy to return the magnetization in the region, following the application of torque to the member, to the single circumferential direction when the applied torque is reduced to zero, whereby the magnetoelastically active region produces a magnetic field varying with the torque. Magnetic field sensors are mounted proximate to the magnetoelastically active region and oriented with respect thereto to sense the magnitude of the magnetic filed at the sensors and provide the output signal in response thereto. At least the magnetoelastically active region of the member is formed of a polycrystalline material wherein at least 50 % of the distribution of local magnetizations lie within a 90°C quadrant symmetrically disposed around the single circular direction and having a coercivity sufficiently high that the field arising from the magnetoelastically active region does not magnetize regions of the member proximate to the magnetoelastically active region to give rise to parasitic magnetic fields which are of sufficient strength to destroy the usefulness, for torque sensing purposes, of the net magnetic field seen by the magnetic field sensor means.
