Title: 2-Keto-diazacycloalkane-urethane oligomers and UV light stabilized compositions
Inventor: NAE SON PYONG
IPC: C08L101/00
Filed: 1983-05-04
Abstract: Novel compounds have been discovered in which a bis compound of a polysubstituted 2-keto-1,4-diazacycloalkane ("2KDZC") provides a bridge between diisocyanate groups so as to form an oligomeric 2KDZC-urethane ("2K-U" oligomer) having from 2 to about 15 repeating units. The bis compound bridge itself consists essentially of two distally linked polysubstituted 2KDZC moieties, and the 2K-U oligomer formed consists essentially of two 2KDZC moieties linked through their N' atoms, which moieties in turn are distally linked to urethane groups through the N<sup>4</sup> atoms of the 2KDZC. Such 2K-U oligomers unexpectedly contain a self-limiting number of 2K-U repeating units which happens to provide 2K-U oligomers which are desirable and highly effective u-v light stabilizers in organic materials. More specifically, this invention provides a novel class of polymeric hindered amine-urethane derivatives, particularly piperazinone bis compounds which may be distally linked to each other in a single step reaction utilizing an appropriately substituted diamine, a haloform such as bromoform or chloroform, in one of several known syntheses for making 2-keto-diazacycloalkanones, some of which syntheses may preferably utilize a phase transfer catalyst. This bis compound may then be hydroxyalkylated and reacted with an appropriate diisocyanate.

Abstract: The sheet-metal vertical suspension strip (3) of a suspension device for ceilings is inserted with a hammer head-shaped anchoring piece (5) into insertion slots (12) of a downwardly open, trough-shaped girder (6) and turned about its longitudinal axis. Since the anchoring piece (5) is longer than the distance between the two side walls (9) of the girder (6), the two ends of the anchoring piece (5) bend in this process, so that the latter assumes an approximately S-shaped configuration and can no longer be pulled out of the insertion slots (12). The anchoring of the suspension strip (3) in the girder (6) is thereby positively secured. <IMAGE>

Abstract: The invention is directed to an ophthalmic lens having a marking and a method of producing the same. The lens is suitable for spectacles and the like. The method includes applying a removable adhering substance to a region of the surface of the lens body so that the peripheral outline of the substance corresponds to the marking to be formed. Then, an anti-reflection coating is applied to the lens body and, at a time thereafter, the adhering substance and the portion of the coating covering the substance is removed thereby causing a recess to be formed in the coating having a peripheral outline defining the marking. The marking formed in this way is practically invisible to a person wearing spectacles equipped with the lens of the invention. On the other hand, the marking is clearly visible when viewed in reflected light.

Inventor: GOODING DAVID NORMAN
IPC: G06F11/10
Filed: 1984-06-15
Abstract: A failure detection apparatus is disclosed for detecting the existence of abnormal circuit conditions in a circuit, the abnormal condition causing erroneous data to be transmitted from one circuit to another circuit, via interface lines. Since spare interface lines are not available, the existing interface lines (11) must be used to determine the accuracy of the transmitted data. A gate line (13), interconnecting adjacent intergrated circuits (10, 12), gates the odd and the even data bytes of the data from the one adjacent integrated circuit to another. If the gate line fails, or otherwise experiences an abnormal circuit condition, the odd and the even data bytes will not be gated from the one adjacent integrated circuit to the other in the proper sequence. With the present invention, the proper sequence is checked. The even data bytes are transmitted along the existing interface lines from the one adjacent integrated circuit to the other with an odd parity; however, the odd data bytes are transmitted along the existing interface lines with an even parity. The receiving integrated circuit determines whether the even data bytes were received with the odd parity and whether the odd data bytes were received with the even parity. An error signal is generated when the even and odd data bytes are not received with the odd and even parity, respectively. The error signal indicates the existence of the failure gate line.

Inventor: KLEIN HILTON J
IPC: G01N33/04
Filed: 1984-06-12
Abstract: The presence of beta lactum ring-containing cephalosporins and penicillin is determined in biological liquids such as milk by contacting the test liquid with a beta lactum ring-containing chromogenic compound and penicillinase and measuring after a predetermined time period the colour developed in the test liquid in comparison with a colour standard. Preferably, the colour standard is provided by contacting the same ingredients and concentrations for the same time period, exept that the liquid is free of beta lactum ring-containing cephalosporin and penicillin. The colourimetric test can be carried out within a few minutes (e.g. 3-15) utilizing a chromegenic compound such as nitrocefin, preferably on a solid phase substrate. The penicillinase attacks both the beta lactum ring of the chromogenic compound and any beta lactum ring-containing cephalosporin and/or penicillin present in the test liquid. The generation of colour due to breakage of the chromogenic compound's beta lactum ring is correspondingly reduced as the concentration of the beta lactum ring-containing antibiotic increases in the test liquid. Therefore, the method permits measurement of the concentration of such antibiotic in the test liquid. The method is simple, inexpensive, rapid and effective and can be run on equipment which is readily available in most laboratories.
