Abstract: ABSTRACT OF THE DISCLOSURE         Novel apparatus and method of multi-shed weaving are disclosed herein.  In the improvement of the weaving apparatus, the shed retaining means includes shed-retaining members for insertion into each of the sheds to retain the sheds and to form a plurality of continuous substantially closed channels, each channel being formed in a corresponding one of the retained sheds.  In addition, the inserting means includes a plurality of fluid jets arranged to insert the weft threads into the channels formed by the shed retaining means, such that each fluid jet is substantially con-strained within a corresponding one of the channels by associated shed-retaining members during the insertion of a respective weft thread, and each weft thread is substantially constrained within a corresponding one of the channels by associated shed-retaining members until its respective retained shed is released.  The improved apparatus includes first impart-ing means for imparting movement to the fluid jets, such that the fluid jets move alongside the retained sheds and such that the fluid jets move in generally the same direction as the retained sheds during the insertion of the weft threads thereinto, and first synchronizing means for synchronizing the movement of the fluid jets with the retained sheds, such that each fluid jet moves conjointly with a corresponding one of the retained sheds during the insertion of a respective weft thread thereinto.  In this way, a predetermined number of the weft threads can be inserted substantially simultaneously into a corresponding number of the retained sheds.  The improved method includes the steps of retaining the sheds by inserting shed-retaining means into each of the sheds and using the inserted shed-retaining means to form a plurality of continuous substantially closed Abstract continued.     channels, each channel being formed in a corresponding one of the retained sheds, inserting the weft threads into the channels formed by the shed-retaining means using a plurality of fluid jets, preferably air jets, each fluid jet being substantially constrained within a corresponding one of the channels by an associated shed-retaining means during the insertion of a respective weft thread, and each weft thread being substantially con-strained within a corresponding one of the channels by an associated shed-retaining means until its respective retained shed is released, moving the fluid mets alongside the retained sheds, such that the fluid jets move in generally the same direction as the retained sheds during the insertion of the weft threads, and synchronizing the movement of the fluid jets with the retained sheds, such that each fluid jet moves conjointly with a corres-ponding one of the retained sheds during the insertion of a respective weft thread. In this way, a predetermined number of the weft threads can be inserted substantially simultaneously into a corresponding number of the retained sheds.

Abstract: "ABSTRACT"        A process and apparatus for recovering organic and inorganic matter from waste material wherein the waste material is sterilized and solid organic matter becomes soft when subjected to heat and pressure.  The process may be carried out by first, feeding the waste material into a perforated container 10 mounted within a closed chamber 14 Next, the waste material is agitated and subjected to heat and pressure which sterilizes it and softened the organic matter contained therein.  After heating under pressure, the pressure may be suddenly released from the chamber 10 which forces the softened organic matter outwardly through the perforations 12 of the container, thus separating the organic matter from the solid inorganic matter.  The softened, sterilized, organic matter is then fermented in fermentation chamber 12 to form a mash which may be subjected to further processing in centrifuge 22, distillation column 23 and anaerobic digester 26 to recover fuels such as ethanol and methane, and animal feed supplements.

Abstract: DRUM BRAKE HAVING DUO-MODE ABSTRACT OF THE DISCLOSURE A drum brake assembly includes a pair of brake shoes which are carried by a backing plate and engageable with a hydraulic actuator. The hydraulic actuator is operable to move the pair of brake shoes from a rest position to a braking position.  A strut extending between the pair of brake shoes cooperates with a parking arm to move the pair of brake shoes to the braking position during a parking brake application.  A support assembly on the backing plate is disposed opposite the hydraulic actuator for the purpose of absorbing braking torque developed by the pair of brake shoes.  The support assembly comprises a pair of slots and a lever.  The lever is movable in response to movement of the parking arm to adjust the position of the pair of blocks relative to each other.  In a first position the blocks are in abutment with the backing plate while in a second position the blocks are free to move a limited amount relative to the backing plate.  Moreover, the lever imparts a separating force to the pair of brake shoes via the blocks during a parking brake applica-tion to expand the brake shoes radially.  This expansion is in addition to the movement imparted to the brake shoes by the strut and parking arm.

Abstract: ABSTRACT OF THE DISCLOSURE An improved degerminating process wherein the grain kernels are crushed from the thin edges toward the center while avoiding crushing of the relatively flat side surfaces.  The crushing force fractures the endosperm under and around the germ and squeezes the germ away from the endosperm in a whole condition.  A machine for carrying out the degermination includes relatively rotating discs having corrugations in their facing surfaces in which the kernels are caught and crushed from the thin edges toward the center.  An alternative degerminator machine includes a single rotating disc having curved guide vanes on its, upper surface for guiding the kernels, as, they are propelled outwardly by centrifugal force.  The vanes orient each kernel with its top or bottom edge in position to impinge upon flat impact surfaces which results in a crushing force applied from the thin edge toward the center of the kernel.  Milling processes employing the improved method of degermination utilize, at the front end of the mill, rollers, with fine corrugations which are normally used only at the end of a long succession of rollers in a conventional differential milling operation. The rollers are adjusted to minimize penetration of the germ to thereby maintain it in a whole condition and produce high quality fines that remain in the prime product streams.

Abstract: Mold Having A Helix For Casting Single Crystal Articles Abstract A ceramic shell mold for directional solidifi-cation of a single crystal metal article has an improved starter section which converts columnar grain growth to single crystal grain growth.  The pitch or lead of the helix is chosen so that the separation between adjacent turns of the helix is less than twice the thickness of the layered ceramic shell material which comprises the mold.  Thus, when the ceramic shell mold is formed by the repetitive application of layers of ceramic to a wax pattern, the gap between adjacent turns of the helix will be bridged when the mold has reached 50-80% of its final thickness.  Then, continued accumulation of ceramic layers bridges the turns of the helix thereby giving it strength.  A helical passage diameter in the 8-10 mm range significantly increases single crystal casting yields compared to smaller diameters commonly used heretofore.
