Abstract: A wireless control system for lighting or the like has a central processor that receives commands from keypads and other control devices, and sends commands to dimmers and other controlled devices. The central processor also receives status reports from the dimmers and sends updates to the keypads, in order to ensure that displays on the keypads are up to date.

Abstract: A toilet seat assembly, useable by either an adult or a child, comprises a first adult-sized toilet seat, a second child-sized toilet seat, and a lid for the seats. Each of the first and second toilet seats and the lid is mounted separately to a hinge pin, which is itself mounted to the toilet bowl. The first toilet seat is mounted to the hinge pin at two points, one on each side of a point at which the second toilet seat is mounted.

Abstract: The invention relates to an analog of human .alpha..sub.1 -antitrypsin characterized in that it is all or part of the protein corresponding to human .alpha..sub.1 -antitrypsin in which, in 358 position, the amino-acid is selected from among arginine and little or non-oxidizable natural amino-acids when they are integrated into a protein.

Abstract: The present invention relates to vectors for cloning, in a host cell, hirudin or an analog of hirudin, characterized in that it comprises the gene for encoding hirudin or an analog of hirudin, and the elements for the expression of this gene in said host cell, said coding gene beginning, after the starting sequence, by an Ile codon and a Thr codon. This invention also relates to the process for the preparation of hirudin or analogs of hirudin as well as the hirudin or anologs of hirudin obtained.

Abstract: The present invention relates to variants of hirudin containing an amino acid different from the amino acid in the natural form at position 47 or 63.

Abstract: The Instrument Landing System Calibrator employs a combined analog radio frequency downconverter with a digital control system for analysis of difference in depth of modulation of tones generated by an instrument landing system localizer and glide slope transmitters. Signal sensitivity and accuracy is increased by elimination of system and phase noise present in purely analog designs and hybrid analog digital designs where digital signal processing is conducted at audio frequencies. Digital signal processing is conducted at video frequency with a single heterodyne from VHF and UHF frequency through selectable crystals. Selection of ILS channels is extended by the use of high speed video digital processing in conjunction with the use of selectable filters and selectable crystals to include all ILS channels.

Abstract: The present invention relates to hirudin variants having a modified peptide structure, relative to a parent hirudin variant. The new hirudin variants of the present invention display improve biological properties relative to the parent variant.

Abstract: The present invention relates to a vector for the expression of the protein of human .gamma.interferon in bacteria, of the type containing the gene which codes for the protein of human .gamma.interferon and the plasmid elements which provide for the expression of this gene, wherein the 5' end of the sequence coding for the protein is as follows: ##STR1## The bacteria transformed by these vectors enable .gamma.-IFN to be produced in high yield.
