Abstract: 41-263/U1.15 IMPROVED PROSTHETIC FIXATION TECHNIQUE    Abstract of the Disclosure In order to reduce the incidence of artificial joint failure at the interface where the prosthesis is bonded to the bone by cement, the artificial prosthesis is provided with  openings,  and  is  clamped  in  place  to  provide  a peripheral seal around the end of the bone to which it is being  secured.   Then  the cement  is applied  through the prosthesis under pressure, and the pressure is maintained until the cement hardens.   The prosthesis may be provided with both input and output openings so that, as the cement is forced  into  the space between  the prosthesis and the cortical bone structure, material  including blood and marrow contents will be forced out the exit apertures and the pressurized  cement will  thereafter make good direct contact with both the bone and the prosthesis, to insure a lasting bond.  The rim of the prosthesis and the matching bone surfaces may be specially prepared to provide a good pressure tight seal.

Abstract: ABSTRACT   DATA CARD AND MAILER DATA MATCH/INSERTER SYSTEM     Thw present invention relates generally to systems for attaching data cards to pre- addressed mailing forms.      Despite the massive volume of mailing of credit, identification and like cards in today's  economy there has yet to have been provided an effective and efficient means for attaching such cards to mailing forms.      The present invention provides an automated system for inserting data cards, e.g., charge, credit, identification and similar type cards, into preprinted  and addressed mail-ing forms.  A computer, with suitable operator intervention controls the automatic asynchronous operation of the overall system.  Each mailing form bears the account number and mailing address of the intended card recipient, and a designation of the number of cards to be inserted.  The cards are pre-embossed and encoded, and supplied in  number and sequence corresponding to the requirements of the succession of forms.   The forms advance in succession from a fan-fold continuous strip through a read station and into an insert station. cards are picked from the supply in individual succession and transported past a read station at which account number data is read  from the card for comparison with the data of the form currently positioned in the insert station.   The insert station includes a number of bins corresponding to the card insert positions on the form and is controlled  to receive the proper number of -1a-correctly matched cards in the appropriate bins for the form.  Should a no-match condition occur or if the corresponding number of proper cards is not satisfied, the card transport terminates to permit a visual operator check.  Operator controls permit selectively rejecting cards and form  where matching requirements are not met and manual overrides for correction of same and for re-initiating automated operation.  Forms with the proper inserted cards are automatically burst from the strip and proceed through a folder to an output transport for stacking in sequence into an output hopper.  Sensors monitor various critical functions to assure accuracy in the automated operations.
