Abstract: TEST COMPOSITION DEVICE, AND METHOD      FOR DETECTING BILIRUBIN                ABSTRACT OF THE DISCLOSURE    An improved test composition, device, and method for detecting bilirubin in urine.  The test composition includes a diazonium compound reactable with urinary bilirubin to produce a color change, an acid pH producing constituent, and a novel potentiating agent for the test reaction.  The potentiating agent is an adduct of a  ureido compound and an organic sulfonic acid or a salt form thereof.  Particularly useful as the ureido constituent of the adduct are urea and substituted and unsubstituted cyclic ureido compounds, particularly those belonging to the xanthine family.  The test device comprises a carrier, such as an absorbent matrix, incorporated with the test composition.  The test method is carried out by contacting a urine test sample with the test composition and observing any resulting colorimetric response.

Title: High speed partition assembling method and apparatus
Inventor: PETERS CHARLES L JR
IPC: B31D3/04
Filed: 1976-11-29
Granted: 1979-05-29
Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to  methods and apparatus for assembling multi-cell partitions to be inserted in pack-ing boxes.  All attempts to speed partition assembly have been severely hampered because of the numerous start-stop operations required, i.e., intermittently moving parts to receive strips and orient them vertically, move the strips in parallel relation to the assembly station, hold the strips momentarily stationary and poised with their notches aligned, then effecting vertically reciprocal movements to form the partition and return for repeat operation, and collapsing the formed partition for removal and tying.  The present invention provides a high-speed continuous assembly method and an apparatus for carrying out the method.  Ac-cording to the present invention, the partitions are assem-bled by inserting the tabs of each of a first set of notched strips into grooves in one face of an elongated bar, and by inserting the notched edges of the other set of notched strips into respective slots in the bar, wherein each slot is located between the successive grooves.  The first set of notched strips are  moved at an angle with respect to the other set of strips, and drives for the sets of strips are synchronized to effect interleaving of the tabs and inter-secting and interlocking of the sets of strips via their notches.

Abstract: ABSTRACT OF THE DISCLOSURE      A titration technique for measuring the surface in a papermaking colloidal suspensions, particularly on the furnish in a papermaking process.  The surface charge measurements are used to determine the optimum conditions for maximizing the drainage rate and first pass retention on a papermaking machine.  The amounts of a cationic and anionic polymer that adsorb onto the surface of the headbox furnish components are measured by a colloid titration technique and the surface charge is calculated.  A furnish having a met positive surface charge on its suspended particles adsorbs more anionic polymer than cationic polymer.  The opposite is true in a negatively charged system.  The ratio of the amounts of each polymer adsorbed onto the surface of the suspended particles in the furnish is determined by the sign and magnitude of the surface charge of the system.  The ideal surface charge is determined experimentally for each paper or board machine and then can be maintained on the papermaking machine by adjusting pH, alum level, broke addition and wet additives.

Abstract: ABSTRACT OF THE DISCLOSURE     A record processor employing a novel developing system, toner module and method in which a quantity of toner fluid is held adjacent to an electrostatic latent image on a film, in a substantially quiescent state, for a sufficiently long period to insure migration and adherence of toner part-icles to the image, is disclosed.  A set small quantity of fluid is drawn into a development chamber formed adjacent to the film which chamber is sized and shaped so as to facilitate the fluid reaching a relatively quiescent state quickly and which fluid is held in the chamber by a natural meniscus dam at a sharp edge formed across the flow path of the toner.  Because the toner flow is stopped during the short development period, streaking of the film can be largely eliminated as this is mainly due to turbulence in the toner flow.
