Abstract: A method for the quantitative assay of n different analytes, where n is at least 2, is provided. The method consists of the following steps: (a) At least one labeled detector-binding partner is added to a test sample containing the analytes. This leads to the formation of detector-analyte complexes, each of which consists of one analyte molecule and one detector molecule. The number of detector binding partners x equals n?1. Each detector-binding partner binds to at least one analyte. At least one of the detector-binding partners can bind to at least two analytes. (b) The detector-analyte complexes formed in step (a) bind to capture-binding partners and form detector-analyte-capture complexes. The number of capture-binding partners y equals the number n of the analytes. Each capture-binding partner is specific for at least one detector-analyte complex. (c) The time-resolved formation of the detector-analyte-capture complexes is measured.

Abstract: In a factory prefabricated drive system conversion unit for the handrail of an existing escalator, the drive system conversion unit includes a channel member adapted to be fixedly connected to an existing escalator structure, with a rotatable friction wheel being mounted between the channels and driven via a chain drive, having a plurality of pressing rollers, and a lever-operated tensioning device, with a set of cluster rollers, having a plurality of rollers, being mounted on a cluster roller base plate arranged on each side of the friction wheel, and also including a handrail turn around with a clamped roller chain having a plurality of both roller and chain links, as well as end pieces and intermediate guide members. Directionless cluster roller bases as well as directionless channels can also be utilized to simplify and speed up the conversion operation.

Abstract: A system for applying a uniform band of liquid primer material to the marginal edge surfaces of glazing units upon which a plastic frame or gasket member is to be molded in place. A family of interchangeable applicator tips is provided for use with a dispensing device adapted to provide an on-demand supply of primer material to the tip in use. The different applicator tips of the family have configurations particularly adapted to applying bands of primer material along selected peripheral margins of a sheet member. Each is of a composite construction including a relatively rigid base member covered by a soft absorbent body for contacting and transferring to the sheet surface the layer of primer material. The tips are readily attachable to and removable from the primer material dispensing device.

Abstract: A digital monitor for monitoring the operation of a synchronous digital system. Proper operation of the monitored digital system is determined by storing a predetermined sequence of digital numbers in a memory. The bit patterns generated by the system being monitored are utilized as addresses to read the stored digital numbers. After each read cycle the digital number read from the memory is examined to determine if it has the proper value. If the value is not proper, a memory is set indicating that the system being monitored has malfunctioned. Additionally, the number of bit patterns checked during each cycle of the system is determined. If the correct number of patterns are not checked, the memory is also set indicating that a malfunction has occurred. Apparatus for monitoring a selected number of analog signals such as power supply voltages is also provided. Either of these tests may be inhibited by signals from the system being monitored or by signals from an external source.
