Abstract: A method and apparatus are disclosed for detecting defects in susceptors of microwave food containers during production of such containers. The method comprises the steps of advancing the microwave food containers in a downstream direction along a processing path; subjecting each microwave food container as it moves along the processing path to microwave radiation sufficient to heat the susceptors of the container without destroying the susceptors of the container; obtaining an image preferably in the infrared spectrum of the heated susceptors of each container; determining if the image is indicative of a defect in the susceptors of each container; and removing from the processing path containers that are indicated to have defective susceptors. The apparatus includes a conveyor that moves containers through a first microwave absorbing cavity, a resonator cavity wherein containers are subjected to microwave energy, and a second microwave absorbing cavity wherein an image of each container is obtained.

Abstract: A safety hummingbird feeder having a substantially cylindrical reservoir, an elongate feeding tube, and a cap. The reservoir has a reduced surface area and is intended to hold a limited amount of liquid sugar solution to reduce or eliminate spoilage and molding. The feeding port tube is made of soft, flexible material and may include a plurality of slits configured to prevent a withdrawing hummingbird from injuring its bill. The hummingbird feeder maximizes safety for a feeding humming bird by reducing or eliminating intestinal injury commonly caused by ingestion of spoiled and/or molded liquid sugar solution and the flexible feeding port tube minimizes the risk of bill injury for a retreating hummingbird.

Abstract: Analytical apparatus for analysing at least one substance has an array of sensors (1) driven by an electronic driver (14) for operating each sensor. The signals produced by the sensors are received by a receiver (82), and the apparatus includes one or more calibration elements connected to the driver and the receiver for enabling changes in parasitic losses in the apparatus to be determined. The invention is particularly applicable to apparatus in which the sensors are electrical-mechanical transducers, individually connectable (in sequence) to the driver and receiver by a corresponding array of switches forming part of an interface (4).

Abstract: A two-color radiation detector includes a mesa-type multi-layered mercury-cadmium-telluride detector structure monolithically integrated on a substrate.
