Abstract: APPLICATION OF:  DONALD L. RICHARDS FOR:  COMPRESSION FITTING                      A B S T R A C T     A pressure and liquid tight compression fitting particularly adapted for attachment to a beverage container. An externally threaded body portion of the fitting is inserted through a wall of the container and is clamped to the wall by means of a nut.  A first pressure seal is effected by an O-ring received in a groove formed in the face of the nut in contact with the container wall.  A first liquid seal is effected by a thin lip formed at the outer edge of the nut, beyond the O-ring.  A combined second pressure seal and second liquid seal is effected by interfitting tapered sections of the body portion and the nut beyond the threaded connection between the body and the nut.

Abstract: ABSTRACT OF THE DISCLOSURE           In accordance with this invention, it has been found that carbon analogs of 6.beta.-aminopenicillanic acid and biologi-cally active derivatives thereof. can be formed from esters of 6-oxopenicillanic acid.  For example 6.beta.-phenoxyacetylmethyl-penicillanic acid - a carbon analog of penicillin V, may be formed from an ester of 6 -oxopenicillanate.  The ester of 6-oxopenicillanic acid is formed by a diiospropyl carbodiimide/ dimethyl sulfoxide oxidation of the corresponding ester of 6.alpha.-hydroxypenicillanic acid.  The carbon analogs are formed by a Wittig reaction of the ester of 6 oxopenicillanic acid with a suitable acylmethy1enetriphenylphosphorane followed by satura-tion of the newly formed double bond and removal of the protec-tive ester group.

Abstract: ABSTRACT        An  apparatus  for  filtering  particulate  material from  air  and  for  removing  the  particulate  material collected  upon  a  filter  is  disclosed.    The  apparatus includes  a  housing  having  an  air  inlet  and  an  air outlet,  and  a  hollow  longitudinally extending  filter  is secured  within  the  housing.   One  end  of  the  filter  is removably  secured  relative  to  the  housing  so  that  the longitudinal   axis   of   the   filter   extends   generally vertically.   The other end of the filter is closed.     A filtering chamber  is defined around the outer surface of the  filter.    The  chamber  is  in  communication  with  the air  inlet  whereby  air  moving  from  the  inlet  to  the outlet  passes  through  the  filter  into  the  interior thereof  and  deposits  particulate  material  on  the  outer surface  of  the  filter.    A  mechanism  is  provided  for removing the particulate material collected on the outer surface  of  the  filter.   The mechanism  for  removing  the particulate  material  includes  a  device  connected  to  the closed  end  of  the  filter  for  causing  the end  to rotate and thus twist the filter.   The mechanism causes a rapid rotation  followed  by  a  counter  rotation  which  shakes loose particulate matter  on  the  filter  and causes it to fall away to be removed therefrom.   The rotation is pre-ferably done intermittently.

Abstract: ABSTRACT OF THE DISCLOSURE Cyclic dimethylpolysiloxanes are prepared by heating a mixture containing linear or branched organopolysiloxanes consisting of at least 50 mol percent dimethylsiloxane units and aqueous sulfuric acid in which the aqueous sulfuric acid contains from 50 to 85 percent by weight of sulfuric acid in the absence of an organic solvent while simultaneously recovering the cyclic dimethylpolysiloxanes thus formed.  This process can be carried out at lower temperature than heretofore possible, and it does not require anhydrous conditions, nor does it necessitate the separation of the catalyst. The process produces higher yields of cyclic dimethylpolysiloxanes than was obtained heretofore in the same size equipment and in a shorter period of time.

Abstract: ADAPTIVE ALIGNMENT FOR PATTERN RECOGNITION SYSTEM     Abstract The invention provides a pattern recognition system in which the visual image of the scanned character or pattern is placed within a defined area, referred to as a video space, which contains ideally only picture elements associated with the character to be recognized.  Initial align-ment of the visual image in the video space is made by one of several prior art techniques (e.g., mark on the form).  The pattern of picture elements in this video space is analyzed to determine what the visual image represents and the coded representation of this character is transmitted to associated equipment which includes apparatus for speci-fying the ideal coordinates or position of the recognized visual image in the video space.  To aid in alignment of subsequent visual images in the video space, selected alignment features of the analyzed visual image are computed and these selected features are compared with ideal feature alignment values for the particular character being recognized. The differences between the selected feature values and the ideal feature alignment values are used as alignment correction values for subsequent characters to be aligned in the video space.  The recognition of these subsequent characters is more accurate because of the enhanced alignment of the visual images in the video space.
