Abstract: A magnetic sensor is provided with a housing in which a carrier is inserted. The carrier is particularly shaped to retain a permanent magnet in a particular position relative to a plurality of electrical conductors and a substrate on which a magnetically sensitive component is attached. The carrier and its associated components is inserted into a housing which can be deformed to permanently retain the carrier within a cavity of the housing. All of the components of the sensor are designed to be easily assembly along a common axis to facilitate automatic assembly and manufacture of the sensor. The magnetically sensitive component can be a Hall effect element that is associated with other electrical components which are also attached to a substrate that is disposed proximate a front end of the carrier.

Abstract: A shipping, storage tray for protecting the surface integrity of a sensitive brittle plate, such as glass, placed therein. The sensitive plate is cushioned along its lower peripheral edge on ridge and groove shaped side walls of a ductile, conformable support tray which prevent surface contact of the plate and the tray bottom. The edges of the tray are folded back and beneath the tray exterior to prevent flakes from the raw sheared edges from being deposited inside the tray and on the plate surface. A chemical coating to enhance wetability of subsequent photo-sensitive coatings on the plate surface is deposited in the tray bottom.
