Abstract: Abstract of the Disclosure A flat glass manufacturing apparatus is disclosed which comprises a glass melter and molten glass conditioner connected to a forming chamber which contains molten metal on which a continuous sheet of flat glass may be formed.  The molten glass conditioner is connected to the forming chamber by a molten glass delivery means which includes a convex threshold over which the molten glass flows onto the molten metal.  Molten glass contact with the threshold member is minimized in that most of the glass entering the forming  chamber has not contacted the threshold member and that which has moves relatively slowly in comparison to the general flow of molten glass over the threshold member.

Abstract: ABSTRACT OF THE DISCLOSURE          Fibrous material having utility in the production of numerous and differing products is produced from refuse by a continuous process after separation and removal of undesirable constituents such as dirt, glass, ferrous and non-ferrous metals from the refuse.  Individual remaining particles are then reduced in size and suspended in a water slurry.  The slurry is then subjected to centrifugal acceleration to remove any glass, metallic, or other relatively dense particles that may remain therein.  The resulting slurry is sterilized by continuous cooking to thermally destroy all major pathogens and/or parasitic organisms.  The solids content is then increased and additives introduced into and mixed with the solids following which the mixture of solids and additives is rolled to produce granules of a desired size and the resulting product is dried.

Abstract: DATA BUFFER RETIMING CIRCUIT by Alvin L. Pachynski, Jr.                     ABSTRACT OF THE DISCLOSURE  A data buffer retiming circuit makes use of a plurality of buffer storage cells into which serial bit streams are sequentially written, in order to obtain correction for phase jitter.  A write clock signal is derived from the serial bit stream and is used to sequentially write the digits into the cells.  A stable clock source is used to provide the basic timing for sequentially reading the bits out from the buffer storage cells, and a logic circuit is used in conjunction therewith to obtain the retimed serial bit stream.  The write and read timing signals should have a maximum time separation to allow for maximum correction of phase jitter, and it is critical that the write and read signals should alternate. A monitor and reset circuit compares a selected write signal with a selected read signal and, where a violation of the alternating write-read condition occurs, the circuit resets the write timing and holds it until the read timing has attained a particular state.
