Title: Sensing overload in a geared drive
IPC: F16H35/10
Filed: 1979-11-26
Abstract: A geared drive includes at least two meshing gearwheels (104, 105).   In order to sense an overload condition, the separating force acting between the gearwheels is sensed by a transducer (114) which produces an output signal varying in accordance with the magnitude of the sensed force. The output signal is compared in a control circuit with a prescribed reference value so as to produce an output indication in response to the output signal exceeding the prescribed reference value. The control circuit can produce an electric signal as the output indication which is used to render the geared drive ineffective. Suitably, the geared drive is employed in a mining machine haulage unit. <IMAGE>

Title: Drip dispensing apparatus
Inventor: O'HARA JAMES BRIAN
IPC: A01G27/04
Filed: 1981-09-11
Abstract: Apparatus for dispensing liquid at a constant drip rate for use in watering plants, by maintaining a constant head of water comprises an open-ended container 1 which is inverted into an open-topped bath 4 above an aperture 7 through which a wick 8 leads to the plant growing medium to be watered. The container 1 is a close fit in the bath 4 except at a local deformation 5 in the bath wall which exposes the surface of liquid to atmospheric pressure. An aperture 6 in the wall of the container 1 can be aligned with the deformation 5 by rotating the container so that the uppermost extent of the aperture exposed defines the equilibrium depth of liquid in the bath under atmospheric pressure, which is the effective head above the wick 8. The aperture 6 has an upward extent that varies about the periphery of the container, thereby allowing the head of liquid to be varied by rotating the container. <IMAGE>

Patent GB-2090487-A (GB)
Title: Stepper motor control circuit
IPC: H02P8/12
Filed: 1981-11-06
Abstract: A digital input signal is fed through an interface to a logic phase control which decodes the signal to provide a plurality of phase signals in a predetermined relationship for driving a synchronous DC stepper motor. The phase signals are fed to corresponding phase drivers (40-43) which amplify the pulses of the phase signals before they are applied to the corresponding phase windings of the stepper motor. Each phase driver includes an operational amplifier (U1) and a power transistor (Q1-Q4) connected in a closed loop to provide a current pulse having a constant predetermined peak amplitude to the corresponding phase winding during acceleration of the motor. The inductive time constant of the motor phase windings is thus overcome so that an applied mechanical load can be rapidly accelerated without stalling and the absence of dropping resistors minimizes power dissipation and heat generation. A pulse detector turns off the phase drivers after a predetermined time interval following the last pulse of the digital input signal to provide a time brake holding torque and near zero standby power consumption. Components (eg Q9 and CR1) in the circuit are provided for protecting the power transistors from breakdown due to back emf signals generated in the phase windings. <IMAGE>

Title: A Stepping Motor
IPC: H02K37/18
Filed: 1981-12-17
Abstract: In a homopolar permanently- excited single-stator stepping motor, the rotor is formed, in the axial direction, by at least two annular magnets 8 which are separated, in each case by grooved flux-conductor discs 6. The magnets 8 are arranged with their poles in opposition, the adjacent flux conductor discs 6 being in each case displaced with respect to one another by half the groove- spacing. The discs 6 have a diameter/length ratio of at least 2.5:1. The arrangement reduces eddy current losses and allows magnets of low residual induction to be used. The invention can be used in the field of electrical machinery construction, as well as for special drive-mechanisms for use in electronic data-processing. <IMAGE>
