Abstract: A  packing  material  having  improved  chemical resistance  formed  of  poly(phenylene  sulfide)   yarn  and polytetrafluoroethylene yarn is provided.  Each of the yarns may be treated with PTFE dispersion and,  optionally,  with graphite.   The two yarns may be twisted together or laid-up side-by-side and braided together and the structure may be impregnated with a polytetrafluoroethylene based binder and lubricant.    The  resulting  packing  material  has  improved temperature characteristics,  heat transfer characteristics, wear resistance, provides a dense impervious packing and is dimensionally stable in addition to the improved chemical resistance.   A packing material prepared from yarns treated only with a PTFE dispersion is especially useful in the paper making industry and for other applications wherein dark colored yarns are not permissible.

Granted: 1992-03-31
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for determining the quenching angle in inverter valves, in which the pulse-shaped deviations, which occur in the valve voltages due to the current commutations as compared to the corresponding fundamental waveforms, are blanked out in the form of voltage blocks.  For the duration of the quenching angle, a binary measuring signal is generated which is triggered by an end-of-conduction pulse and is terminated by a zero voltage crossing pulse.  The end-of-conduction pulse indicating the completion of the commutation is formed by the flank at the end of the voltage shift caused by the preceding commutation in the valve voltage as compared to the fundamental waveforms.

Abstract: The invention provides a biograting for use in determining the amount of an analyte in a sample in a light diffraction assay. The biograting has a smooth, solid surface that reduces nonspecific binding, thereby providing better resolution than in prior art systems.  A process for manufacturing the biograting comprises adhering a uniform layer of hybridizing reagent on the smooth, solid surface and exposing the surface to UV radiation through a shadow mask with diffraction grating lines to selectively deactivate the hybridizing reagent. This process produces a biological diffraction grating design of lines of active hybridizing reagent. The invention includes a biograting wherein the hybridizing reagent is a nucleotide sequence. This biograting is used to detect a specific DNA sequence in a diffraction hybridizing assay.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of assigning hall calls to a plurality of elevator cars  which biases the assignment process to balance the number of cars serving up and down service directions.  Prior to each call assignment update the method determines the number  of  cars  serving each service direction (78, 80, 82).  A predetermined relation-ship (88) between these two numbers is used to determine if up hall calls should be assigned first, or down hall calls (90, 92, 94, 96).  The balancing of cars serving the two service directions lowers the average waiting time, and it results in dispersing the cars throughout a building when service  subsides,  to  enable  prompt  service  for  newly entered calls without  the  necessity of moving the cars during periods of low service to be in position for new calls.
