Abstract: METHOD AND APPARATUS FOR FORMING  STEPS IN MANHOLES AND THE LIKE            Abstract of the Disclosure Method ant apparatus for forming steps in manhole structures.  Manhole assembly is comprised of pre-cast concrete sections.  Each such section is formed in an appropriate mold typically comprised of inner and outer mold shells.  The inner shell is provided with pairs of openings arranged in a pre-determined fashion.  Plastic core members are snap fittingly inserted into the openings and are provided with resilient pairs of flanges which cooperate with the marginal edges of each opening to retain the core in proper position and align-ment.  The concrete is placed in the mold.  Once set and cured, the section is removed from the mold.  The plastic core members are snapped free from their locked position with the mold inner shell and remain as an integral part of the cured section.  U-shaped stepped sections are force fittingly inserted into the cores which serve to retain each step member in position.

Abstract: ABSTRACT OF THE DISCLOSURE           A plurality of ground working sections such as culti-vator sections, are flexibly connected together and operatively connected to a hitch pole assembly.  Each section is supported upon a pair of castor wheels mounted on a fore and aft beam pivotally connected to the front and rear of the frame members.          The sweeps or cultivators move in an arc via hydraulic or mechan-ically operated rock shafts and the depth control is by means of controlling the pivotal movement of the fore and aft beams.  This also permits the penetration angle of the sweep or cultivator to be preset and maintained.  For transport, the draw pole is raised and the implement is towed by one end thereof with the castor wheels automatically aligning with the direction of travel thus eliminating folding or raising of sections and permitting prac-tically any length of cultivator or ground working implements to be assembled.

Abstract: ABSTRACT OF THE DISCLOSURE A photosensitive member having at least two electrically operative layers is disclosed.  The first layer comprises a photo-conductive layer which is capable of photo-generating holes and injecting photo-generated holes into a contiguous charge transport layer.  The charge transport layer comprises an electrically inactive organic resinous material containing from about 15 to about 75 percent by weight of N,N'-diphenyl-N,N'-bis(phenyl-methyl)-[1,1'-biphenyl]-4,4'-diamine.  The charge transport layer while substantially non-absorbing in the spectral region of intended use, is "active" in that it allows injection of photo-generated holes from the photoconductive layer, and allows these holes to be transported through the charge transport layer.  This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to light and development.
