A generally round, radially sectioned, molded plastic modular building/home with maximum thermal efficiency and space utilization, requires no foundation.

The subject of this patent application is a door assembly (10) having a knob (38) which, during shipment, is segregated from the rest of the assembly (10) for ease in packaging and storage. The invention includes a unique locking element (62) for securing the knob (38) to the door closure panel (12) when the panel (12) is at a location at which it is to be installed.

Auger conveyor apparatus is described which is adapted to convey bulk material. The conveyor includes a plurality of axially aligned and connected segments which are coupled in such a manner that one segment drives an adjacent segment after limited rotation relative to the adjacent segment. The connected segments are self-supporting, and incoming bulk material has access to the apparatus essentially along its full length. The apparatus may be used in a variety of applications including, among ot...

Fatty, segmented polyester elastomers are provided which are prepared from a mixture having a molar ratio of aromatic to fatty reactants of less than 4:1 and a molar ratio of short-chain diol to long-chain poly(ether) diol reactants of less than 49:1. These elastomers are useful as hot melt adhesives having excellent properties including resistance to embrittlement at low temperatures.

A foot orthosis for correctably realigning and repositioning specific anatomic segments of the human foot consists of three functional components, namely, a heel complex segment and two longitudinal forefoot segments--namely, a medial segment and a lateral segment. The heel complex segment is independently connected to each longitudinal forefoot segment by a connector. The segments function sufficiently independently from one another to consider the device a triplanar foot orthosis.

An enclosure containing an ionizable gas has electrodes mounted in opposition on opposite faces of the enclosure. A first set of electrodes on one side of the enclosure are energized in sequence. A second set of electrodes on the opposite side of the enclosure form a multiple-element character matrix in which groups of elements are electrically commoned so that the number of electrodes, and respective leads thereto, in the second set is less than the number of elements of the matrix. The electro...

A cylindrical wheel has a channel formed at its periphery. A plurality of bolts pass through the sides of the channel and transverse it. A plurality of uniform grinding segements are inserted into the channel. Each segment has a radius on opposite edges. The radius is adjacent to a bolt. Adjacent segments are adjacent to one bolt.

A packing ring for use between two surfaces to be sealed relative to each other is comprised of two ring components each of which is constituted by an assembly of ring segments which are provided with a projection at one end which engages a complementarily configured recess located at one end of an adjacent ring segment thereby providing a circumferentially extending interlocking of all segments of each ring. The ring segments of one ring are circumferentially staggered relative to the segments ...

This invention relates to a valve characterized by a hollow cylindrical body, the interior of which houses a segmented conical plug for axial movement with its apex pointed upstream. A frustoconical seat inside the hollow body also faces upstream and cooperates with similarly shaped surfaces at the base of each plug segment to cam the latter into cone-forming relation upon axial movement thereof in a downstream direction. In closed position these opposed frustoconical surfaces mate to define a c...

A corona charging device comprising an elongated wire electrode and a shield partially surrounding the electrode, the shield being formed of a plurality of conducting segments insulated from each other and biased to a plurality of different potentials relative to the wire. The distribution of charge from the corona device onto an adjacent surface may be controlled by changing the biasing arrangement on the shield segments.
