Abstract: Abstract of the Disclosure A digital-analog converter comprising a reference value adder having its multidigit input coupled to a multi-digit output of a switch unit and a Fibonacci p-code convolution unit which has its multidigit output coupled to a multidigit input of the switch unit.  The Fibonacci p-code convolution unit comprises n stages, each of which, related to a certain bit position in a range from one to n - 2, comprises an AND gate and an OR gate.  Each of the stages corresponding to bit positions from zero to n - 1 comprises a flip-flop, an OR gate and an AND gate.  The set and reset inputs of the flip-flop are coupled, respectively, to the output of the AND gate and to the output of the OR gate, the set input of the flip-flop of the stage of the zeroth bit position is a counting input of the digital-analog converter, first and second inputs of the OR gate of the stage of the ith bit position are coupled, respec-tively, to the outputs of the AND gates of the (i + 1)th and (i + p + 1)th stages, first, second and third inputs of the AND gate of the ith stage, beginning with the (p + 1)th stage, are coupled, respectively, to the reset output of the flip-flop of the same stage, to the set output of the flip-flop of the (i - 1)th stage and to the set output of the flip-flop of the (i - p - 1)th stage, and the remaining inputs of all the AND gates are joined together to constitute a clock input of the digital-analog converter, where n is the length of the Fibonacci p-code and i = 0,1,2, ..., n - 1.

Abstract: ABSTRACT OF THE DISCLOSURE          An end closure cap for a tape sealed assembly with a cylindrical shell.  The closure cap is characterized by a deep dish construction having a high degree of dimensional adaptability making it particularly suited for use with composite shells manu-factured with relatively wide dimensional tolerances.  The cap includes flared and beveled surfaces which make it self-aligning to the shell and elements which, until completion of the applica-tion of a sealing shrink tape, allow escape of air from the shell to facilitate high speed automatic closing of the assembly.

Abstract: Abstract of Disclosure A heated metal plate drying system for drying either green veneer or partially dried veneer can have a plurality of modular hot presses mounted on a frame.  At a loading station, individual sheets of veneer to be dried or redried are fed into a hot press, and at an unloading station the dried veneer sheets are unloaded from the system. Within each individual modular hot press, a direct contact drying process occurs that functions to reduce the moisture content of a veneer sheet down to the desired uniform level such as within a range of from 1 to 10%  The drying process accepts veneer of different species, thickness, and beginning moisture contents and the controlled process variables include contact time temperature and pressure.    Each individual modular press can be multi-opening and has the ability to open and close on command.  Specially designed heated metal plates are part of each press and each plate has substantially parallel grooves on at least one surface.  The modular presses are mounted on the frame such that they may be tilted at the unloading station to facilitate unloading of the dried veneer sheets.  At the loading station, a loading apparatus functions to sequentially feed individual veneer sheets into the openings.  The loading apparatus is pivotally mounted.  Also provided is an aligning apparatus for ensuring proper alignment of each veneer sheet within its respective opening after being loaded.  The modular presses in one embodiment are mounted on a carousel frame structure that is rotatable on a main bearing so each modular press indexes past the loading and unloading stations.

Abstract: ABSTRACT OF THE DISCLOSURE           The specification discloses a plastic pool wall having a groove in its face which includes an embedded metal channel for receiving the bead of a plastic pool liner. The metal channel includes spaced upper and lower walls joined by a base wall, with the upper wall terminating short of the plastic pool wall face.  As a result, the upper surface of the groove is defined in part by the metal upper wall of the metal channel and by the plastic of the pool wall. Consequently, when the plastic liner bead is placed in the metal channel and the groove grouted, grout seals between the plastic pool liner and the plastic of the pool wall.

The mill head structure includes a conical head portion having a central axis and including a rib portion and a gear flange portion. The rib portion extends radially outward from the conical head portion and is arranged for assembling the head structure to the grinding mill so as to stiffen the gear flange portion against deformation under load.  The gear flange portion has a periphery centered about the central axis of the conical head portion.  The mill head structure further includes a plurality of gear rim segments which are positioned in juxtaposed relation around the periphery of the gear flange portion.  The gear rim segments are removably secured with the gear flange portion to provide a continuously toothed gear annulus for accurate meshing relation with one or more pinions. Due to the large size of the grinding mill, the conical head portion comprises a plurality of segmental portions which are arranged in mutually complementary relation.  The novel mill head structure provides for the easy replacement of damaged rim segments.

Abstract: 161,441 CAN/LRS     Abstract Improvements in respirators and particularly in respirators containing visually observable indicator means for indicating the end of the service life of respirator cartridges for use in atmospheres containing hazardous vapors and/or gases are disclosed.  In contrast to the prior art where indicator reliability may be reduced due to its incorporation in a localized pocket or in a window in the sorbent bed, the present invention utilizes a colorimetric indicator in sheet form which is positioned along the inner transparent sidewall of the respirator cartridge.  This indicator reveals the remaining capacity of the entire sorbent bed rather than the condition of a small volume near the probe or window.  In addition, the colorimetric indicators useful in the present invention undergo irreversible color changes when subjected to gases to be detected.
