Abstract: ABSTRACT OF THE DISCLOSURE    A chromatographic device is disclosed.  The device comprises in combination a housing, a strip of bibulous material non-removably confined in the housing.  The strip has a length and width only slightly less than the length and width of the inner walls of the housing.  The inner walls of the housing have means attached thereto for supportively confining the strip in the housing.  The strip is confined so that (1) the front and back of the strip are essentially free from contact with the walls of the housing and (2) the capillary action of the strip remains substantially unchanged, and (3), where the strip is paper, the strip is allowed to expand as it is traversed by the liquid medium.  The bottom end of the housing contains means for enabling contact of a portion of the strip with the liquid medium.  The housing further contains means for visually observing the strip and can also contain indicating means cooperative therewith to assist in determining the result of a chromatographic test.  The present device has particular application in immunochromatography for the determination of the presence of an analyte suspected of being present in a sample.

Abstract: PROCESS FOR THE PRODUCTION OF CITRUS FLAVOR AND AROMA COMPOSITIONS     Abstract of the Disclosure The present invention is a process for the production of citrus flavor and aroma compositions comprising the steps of: a) contacting organic citrus flavor and aroma compounds with a solvent gas having a temperature between its critical temperature and about 100°C (212°F), and having a reduced pressure between about 0.56 and about 1.31, to extract flavor and aroma compounds the majority of which have a molecular weight less than or equal to that of limonene; b) separating the solvent gas and dissolved compounds from the remaining undissolved compounds; and c) separating the dissolved compounds from the solvent gas. This process produces an extract which is enriched in the desirable lower molecular weight flavor and aroma compounds and decreased in concentration in the undesirable higher molecular weight flavor and aroma compounds which could impart off-flavors.          The invention further comprises the resulting flavor and aroma compositions, as well as citrus juice and citrus beverage containing these resulting compositions.

Abstract: SEQUENTIAL AND/OR RANDOM POLLING SYSTEM WITH VIRTUALLY INSTANTANEOUS RESPONSE-TIME            ABSTRACT     A communication system in which a controller ordinarily poll  addressable transponders in a sequential or random manner normally allows the transponders to respond only in their respective assigned time period. Certain of the transponders are connected to allow response in a predefined time segment from those transponders so connected if (1) the transponder is in fact programmed for response during this predefined time segment, and (2) the predefined time segment is now occuring.  By providing the predefined time segment at the same position in the response time period of each transponder, a "public time" is provided to allow virtually instantaneous identification and verification of a high priority interrupt (such as a holdup alarm).  In addition the transponders programmed to respond during public time on a high priority basis can be subdivided into separate groups,  and the groups can be identified at the controller.

Abstract: FANFOLDED TABLET OF A WEB WHICH IS           SEPARABLE INTO SHEETS EACH BEARING A           PRESSURE-SENSITIVE ADHESIVE PATTERN     Abstract A writing tablet is formed from a substantially continuous, fanfolded web of uniform width having transverse paths of weakness, along which the web can be torn evenly into individual sheets of uniform size. One face of the web bears a series of pressure-sensitive adhesive patterns, one pattern on each sheet, which pattern contacts the adhesive-bearing face of an adjacent sheet only in nonadhesive areas.  The pressure-sensitive adhesive and nonadhesive areas are so prepared that each sheet can be cleanly peeled from the adjacent sheet without adhesive transfer, even after prolonged storage. After the tablet has been formed, its sheets can be conveniently and efficiently imprinted in a printer or copier and then returned to tablet form.

Abstract: Abstract The present invention refers to a threaded coupling for percussion drill rods having a diameter of 30 - 40 mm, comprising an external rod thread and an internal sleeve thread, the longitudinal section of said threads having continuously curved tops and bottoms.            In threads of the type mentioned above it is desirable to be able to tighten them to a relatively high degree because otherwise the thread coupling loosenes when used in hydraulic percussive drilling machines of a high frequency.            Significant for the thread coupling of the present invention is that the pitch (S) is 7 - 11 mm, the radii of curvature (R1 - R4), at least for the portions of the tops and bottoms located immediately adjacent the contact shoulder, are 3 - 5 mmm, and that the threads have a height (H1,H2) of 1.2 - 1.6 mm.
