Title: Digital noise cancellation in a metal detector
Inventor: STROSSER RICHARD P
IPC: G01V3/10
Filed: 1988-10-12
Granted: 1996-04-02
Abstract: A method and apparatus for cancelling cyclically recurring noise induced in a magnetic metal detector by movement of ferrous machine parts in the field of the detector provides for periodically sampling the output of the metal detector, delaying each sample for the duration of one cycle of the cyclically recurring noise, and subtracting the samples taken in one cycle from the output of the metal detector during the following cycle.  The delay is accomplished by a delay line or shift register, or by storing the samples under microprocessor control.  If the noise has a first component occuring at a first rate and a second component occuring at a second rate cancellation of both components may be accomplished. The system is especially useful for detecting ferrous tramp metal passing with crop material through the infeed of a forage harvester.

Abstract: ABSTRACT OF THE INVENTION           An apparatus comprising a chemically sensitive sensor material, having an electrical resistance or dielectric constant which changes under the effect of the gases or vapors. According to the invention, this sensor material, which comprises either hydrophobic metal complexes, or a mixture of at least one phthalide and at least one acidic compound, serves as resistance or as dielectric material.  These sensor materials change their ion mobility and/or their ionic concentration under the effect of gases or vapors, thereby changing their resistance or capacitance.  The change in resistance or the change in capacitance can expediently be converted into a frequency change by a multivibrator.  Thus, one obtains an especially simple and very effective sensor for gases and vapors.

Abstract: Abstract:    A growing medium for plants is prepared by mixing a growing material with a highly water-absorbent polymer.  The polymer is an acrylamide polymer cross-linked with methylene bisacrylamide which absorbs water to form a sticky gel.  The polymer may be supplemented with an additive.  The additive is applied in aqueous medium to particles of the polymer so that the  medium  is  absorbed.   Water is then removed by drying to give  loose particles of supplemented polymeric substance which can be mixed with a growing material such as soil or sand.   The additive may be a colouring agent for identification purposes or a plant nutrient or a bacterial strain for soil conditioning.  The polymer can also be mixed with a growing material comprising fibres derived from palm nuts such as coir fibres.  A further additive which can be incorporated in the polymer is a pheromone.
