Abstract
A cutlery detector device is provided for detecting metal objects discarded as trash along with non-metallic trash material. The detector device includes a metal detecting ring or the like mounted at the top of a trash receptacle, in combination with circuitry adapted to trigger an alarm upon passage of a metal object such as a cutlery item into the trash receptacle. A counter may also be provided to count the number of metal objects placed into the trash receptacle.
Claims15
A detector for detecting metal objects in non-metallic material which may be discarded as waste along a predetermined path, comprising:
- (a) an electrically operated metal detecting means mounted proximate to the path travelled by the non-metallic material, and including means for shielding said metal detecting means so that it is not sensitive to metal objects located to the exterior of the path travelled by the non-metallic material;
- (b) electronic circuitry means connected to the metal detecting means, said circuitry means being activated when a metal object passes along the path proximate to said metal detecting means;
- and
- (c) alarm means which is activated by said circuitry means upon activation of said circuitry means to provide an alarm signalling the passage of a metal object along the path.
A method of detecting valuable metal objects which may be discarded along with trash into a trash container, comprising the steps of:
- utilizing a metal detecting device in a position proximate to the opening of the trash container to sense the presence of any metal object which may pass along with the trash into the opening of the trash container, shielding the metal detecting device to prevent sensing the presence of any metal object which may pass along a path exterior to the opening of the trash container, and activating an alarm when a metal object is detected by the metal detecting device.
A detector for detecting metal objects in non-metallic material which may be discarded as waste along a predetermined path, comprising:
- (a) an electrically operated metal detecting means mounted proximate to the path travelled by the non-metallic material;
- (b) electronic circuitry means connected to the metal detecting means, said circuitry means being activated when a metal object passes along the path proximate to said metal detecting means;
- (c) alarm means which is activated by said circuitry means upon activation of said circuitry means to provide an alarm signalling the passage of a metal object along the path;
- and
- (d) counting means activated by the passage of a metal object along the path proximate to said metal detecting means for counting the number of metal objects passing along said path.
