Abstract: A  novel  hyposensitization  agent  was  prepared  by covalently  attaching  a  saccharide,  e.g.  homo-  and  hetero-glycans,  for example,  starch,  amylose,  dextran,  polysucrose, pullulan,  elsinan,  curdlan, gum arabic,  gum tragacanth,  guar gum, xanthan gum, carrageenan, pectin, cellulose, glucomannan, chitosan,  and  lipopolysaccharide,  and their  derivatives  and partial hydrolysates to, a cedar pollen allergen.  The hypo-sensitization agent can be administered to a cedar pollinosis patient  without  fear  of  eliciting  anaphylaxis  and  allergy within  a  shortened  hyposensitization  period  because  the hyposensitization agent much more enhances the producibilities of immunoglobulin G and M antibodies which are specific  to intact  cedar  pollen  allergen,  but  extremely  reduces  the producibility of immunoglobulin E antibody which is specific to the allergen and responsible for anaphylaxis and allergy.

Abstract: TUBULAR CERAMIC ARTICLES, METHODS AND APPARATUS              FOR THEIR MANUFACTURE                           ABSTRACT       The present  invention relates to methods and  apparatus for producing tubular articles of silicon carbide and silicon.          The   articles  contain  silicon  in  both  metallic  and   in chemically combined form.  The method consists of the steps of concentrically  positioning  a  vertical  tubular  columns  of particulate silicon contiguous to a hollow,  vertical  tubular columns of particulate silicon carbide, carbon, or mixtures of silicon  and  carbon,  and heating the adjacent columns to  a siliciding temperature.  The silicon component infiltrates the column containing the particulate silicon carbide,  carbon, or mixtures  thereof,  forming a tubular product.   The apparatus consists  of supply hoppers for holding the particulate  feed material,  a loading means comprised of spaced, concentrically arranged,  tubular  forms.   The  loading means is  positioned within  a vertically positioned electrical induction  furnace.          Particulate  feed  materials  are dry  cast  into  the  spaces between  and  around  the forms.  The loading  means  is  then removed   leaving   separate  vertical,   hollow  columns   of particulate feed materials concentrically arranged within  the furnace.   The  furnace is then heated from top to bottom to a siliciding temperature.  The silicon component infiltrates the column containing silicon carbide,  carbon or mixtures thereof to form a dense, tubular silicon-silicon carbide product.

Abstract: ABSTRACT OF THE DISCLOSURE     A system for processing  a log  or cant  including chippers, profiling  heads,  and  saws  arranged  as  a sequence of coupled operations.   Scanners and  computers determine  the log configu-ration  and  projected  configuration  of  lumber  pieces  to  be derived.  One scanning function is the determination  of the wane area  configuration  in  the  region  of the projected side board edges.  This enables a  determination  of  the  side  board edges including  acceptable  wane  area  and  the  desired  orientation (incline or decline)  of  the  boards  relative  to  the  path of conveyance.   The profiling  heads are  adjustable in response to computer  calculations  to  edge  the  established  side  boards. Stabilizing is  provided and  includes guide anvils positioned at the board edges following the edging operation.

Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE The output shaft of a nut runner for tightening a fastener such as a bolt is first rotated with a lower torque at a higher speed.  When the tightening torque of the output shaft reaches a preset switching torque, torque.  When the tightening torque reaches the switching the lower-torque higher-speed rotation of the output shaft is interrupted, and thereafter the output shaft is rotated with a medium torque at a medium speed.  When the tightening torque then reaches a preset snug torque, the medium-torque medium-speed rotation of the output shaft is interrupted, and thereafter the output shaft is rotated with a higher torque at a higher speed.  When the tightening torque reaches a preset final torque, the higher-torque lower-speed rotation of the output shaft is stopped, thus completing the tightening of the fastener.

Title: Process for removing bran layers from wheat kernels
Inventor: TKAC JOSEPH
IPC: B02B3/00
Filed: 1988-12-16
Granted: 1993-02-02
Abstract: ABSTRACT OF THE DISCLOSURE     Significant improvements to the milling of wheat kernels are possible by sequentially removing the bran layers of the kernels prior to processing in general accordance with the conventional milling principles.  The wheat kernels are preprocessed by means of a number of friction and abrasion operations to peel or strip the various layers of bran from the kernels.  A series of friction machines followed by abrasion machines progressively remove the bran layers and separate the same into generally pre-identified bran layer mixtures.  Up to about 75% of the bran can be removed with the remaining bran being essentially confined to the kernel crease and removed during the conventional milling operation.  Such preprocessed kernels, when milled in the conventional manner, have higher yields due to less bran contamination.  This selective removal of the bran layers also facilitates low cost production of specialty bran products or selective reintroduction of bran layers to flour after, or during, further milling.
