    Abstract: A low pass filter for use in an image band pass filter of a photoelectron spectromicroscope incorporating a virtual potential surface for reflecting electrons below a particular energy and a special charged particle trap or super dump for unwanted electrons. The filter construction with the super dump reduces the proportion of elastically and inelastically scattered high energy electron escaping the filter.

    Abstract: A concrete forming system is provided which incorporates a pair of wall panels arranged in a predetermined upright spaced relation and a skeletal grid assembly disposed between the wall panels and retaining same in predetermined upright spaced relation while concrete is being poured between the wall panels. The grid assembly is provided with a plurality of first rods arranged in spaced relation and spanning the distance between the wall panels. The ends of each first rod are disposed within preformed holes formed in the wall panels. Each rod end has a portion thereof disposed adjacent an exterior surface of a wall panel. A plurality of second rods are disposed between the wall panels and engage interior surfaces of the wall panels. The second rods interconnect with the first rods. Retainer rods are provided which are disposed adjacent exterior surfaces of the wall panels and interlockingly engage the portions of the first rod ends disposed adjacent the wall panel exterior surfaces and retain each wall panel between a second rod and a retainer rod.
