Abstract: An mileage communication system for a vehicle, such as a trailer, is disclosed. Mileage data is communicated to a processor by a sensor. The processor calculates cumulative mileage and encodes the mileage data into a code, such as an ON-OFF code, that is capable of being communicated to an output device. The vehicle operator may activate a user interface that is capable of generating a request signal to be sent to the processor. Upon receipt of the request signal, the processor communicates the code to the output device. In response to the code from the processor, the output device communicates a visual or audible signal, such as an ON-OFF signal, that is capable of being received by the vehicle operator or other user. The signal corresponds to the cumulative mileage data.
Abstract: A powder spray apparatus is described including a powder booth with a scraper bar which reciprocates across the floor thereof to collect deposited overspray powder and supply it to intakes located at each end wall. The intakes are connected by a feed channel to one or more cyclone separators. An exhaust duct may also be provided for air-borne overspray powder which preferably forms part of the feed channel. Powder recovered from the cyclone separators may be passed to a common collection hopper by use of a venturi pump which transfers the powder from each separator to the hopper via a sieve located in a ventilated enclosure above the hopper.

Abstract: The present invention provides novel methods for producing doxorubicin using daunomycin as a substrate. One method employs a genetically engineered host microorganism which is transformed with a vector, preferably a plasmid, which contains the doxA gene. Preferably, the doxA gene, also referred to herein as "doxA", is cloned into a plasmid which is then introduced into the host microorganism, preferably a bacterial host, more preferably Streptomyces, to provide a transformed host microorganism. The doxA gene, when present on a plasmid, confers on the transformed host the ability to convert daunomycin and 13-dihydrodaunomycin, to doxorubicin. The doxA gene encodes a P450-like enzyme which catalyzes the hydroxylation of daunomycin and 13-dihydrodaunomycin at C-14 to form doxorubicin; such enzyme is designated "daunomycin C-14 hydroxylase". Thus, the expression of doxA in the transformed host using a plasmid which contains doxA enables the transformed host to convert daunomycin to doxorubicin.
