Abstract: A mobile suspension arrangement having a central member adapted to frictionally hold in suspension extended wires having related clip members frictionally engaging the wire ends and hanging strings for suspending mobiles.
Abstract: A desk chair particularly designed to have supporting members disposed between guide members having facing complementary grooves, and the supporting members having supporting rollers riding in said grooves whereby the chair responds to movement of the body to retain it in a good posture position, the only force present in said structure being that of gravity.
Abstract: This invention is a familiar design overlying the adjacent toe portion of a pair of childrens shoes. With the shoes properly positioned side by side, a child will see the design as a whole and relate the left foot shoe with its left foot and the right foot with its right foot shoe as the proper positions for the shoes to be worn.
Abstract: A collector of aquatic invertebrates for laboratory study comprising a substantially invisible collector having a removable wide mouth entry portion reducing to a narrow neck inlet passage whereby the invertebrates are secure from escape and are readily removable.
Abstract: A flying toy disc with a pivoted fuselage, the disc flying spinning in flight upon being thrust with a forward spinning motion, the disc having a particular transverse configuration which taken with the pivoted fuselage tends to stabilize the flight of the disc by having air streams co-act upon the lower and upper surface of the disc to stabilize the flight.
Abstract: A reciprocal type of pump structure wherein a piston has a linear function actuated by a pair of coils energized alternately and includes a plurality of tapered flutes. A check valve in an outlet of the structure which stretches to open said outlet under the impact of expelled fluids and of its own volition retracts to the closed position immediately upon the cessation of fluids being expelled.
