Title: Control apparatus for an electrical fence
Inventor: WADKIN THOMAS ARTHUR
IPC: H05C3/00
Filed: 1983-10-29
Abstract: An energiser 10 applies short-duration D.C. pulses to an electric fence 11 and has a switching circuit 12 connected electrically in parallel therewith. This parallel connection minimises the risk of the unit 12 being damaged if lightning strikes the fence 11. The energiser 10 can be switched on and off from a remote location by engaging a probe 20 with the fence 11 and applying an A.C. signal to the latter by means of a control unit 13. This A.C. signal is detected by the circuit 12, which switches the energiser 10 on and off, as the case may be. When a switch 21 in unit 13 is closed, an oscillator 23 and transformer 24 apply the A.C control signal to the probe 20 via a voltage clamping circuit 24. In the unit 12 the A.C. control signals pass via a voltage clamping circuit 24, rectifier 25 and low pass filter 26 to a monostable 27 operating to switch a bistable 14 controlling a relay 15 having contacts 16 in the supply line to energiser 10. Filter 26 blocks the pulses from energiser 10. A pulse stretcher 31 and lamp 32 in unit 13 can be used to detect remotely that the energiser 10 is working. <IMAGE>

Patent GB-2135460-A (GB)
Title: Detecting hidden objects
Inventor: WEISS OSCAR
IPC: G01V3/15
Filed: 1984-01-19
Abstract: Hidden objects in the ground are detected by detecting a localised disturbance in the ground. Unlike conventional detectors the present invention can detect the presence of non-metallic objects. The invention is predicated upon the fact that a buried object causes a disturbance of the local value of the earth's magnetic field due to both the disruption of the soil and the material of the object. The change in intensity of the field will usually be too small to detect reliably, but the horizontal and/or vertical gradients of the magnetic disturbance is detectable. This invention provides a method and apparatus in which a plurality of mutually spaced apart magnetic field detector units (10, 12) are swept across an area of ground suspected of containing a localised disturbance and in which the detector units (10, 12) are responsive to the magnetic field gradient associated with the resulting disturbance of the local magnetic field. <IMAGE>

Title: Power actuated drum brake
Inventor: DEWHURST ALAN
IPC: F16D49/16
Filed: 1984-04-11
Abstract: A power actuated drum brake includes a pair of brake shoe assemblies 1 pivotally mounted on respective brake arms 3 and free to move through a limited distance with the rotation of the brake drum. Braking force is applied by spring means between the brake arms and the brake is disengaged by an electrically controlled actuator 8 moving the brake arms apart. An electric switch 19 (Fig. 2, not shown) is connected in the actuator control circuit and is operated by movement of one of the brake shoe assemblies with the brake drum. When the brake drum is braked and subject to reverse torque, the brake shoe assemblies move to a position in which the electric switch is opened to disable the actuator. The switch is not closed until the drive to the brake drum overcomes the reverse torque. The invention also provides brake shoe assemblies for converting existing drum brakes. <IMAGE>
