摘要:
A compressor diagnostic system incorporates a control which receives a plurality of data streams about various operational features of the compressor. As an example, both temperature and pressure of the suction and discharge refrigerant are taken and sent to the control. Moreover, information with regard to the power being supplied to the motor is taken and stored. All of this information is utilized at a control which compares the information to expected values and determines a fault based upon the evaluation. Moreover, in another feature of this invention, much of this data is stored, and maintained at the compressor. In the event of a compressor failure, this stored information will provide a maintenance worker with a good indication of why the compressor failed.

A molded compressor base (100) is provided for mounting a compressor without requiring mechanical fasteners. The molded compressor base (100) can be used to mount the compressor in any position ranging from a substantially horizontal position to a substantially vertical position. The molded compressor base (100) includes a mounting area that is designed and configured to secure a compressor placed in the mounting area. The mounting area can be configured for a compressor to be mounted in a substantially horizontal position, a substantially vertical position or any position in between. The molded compressor base (100) can also include one or more isolators to secure the compressor and to isolate vibrations from the compressor from the molded compressor base (100). The molded compressor base (100) can damp sound and/or vibrations generated by the compressor or the molded compressor base (100) can be coated with a sound and/or vibration damping coating.

The invention is directed to wastewater treatment and wastewater reuse. A distributed biological treatment system for modification of the sewer biofilm through the mechanism of competitive exclusion by strategic dosing with facultative bacteria is illustrated, in conjunction with a novel membrane biological reactor (MBR)/biological breeding reactor (BBR) package plant, a plurality of which are likewise designed for strategic placement throughout the sewer/collection system infrastructure. The inclusion of the MBR/BBR plants at specific locations within the distribution system provide upstream water reclamation, thereby facilitating more efficient operation of the downstream wastewater treatment plant and providing for water reuse at intermediate points within the distribution network, as well as a means for concentrating the facultative bacteria which has been dosed to various points in the system, which can then be re-inoculated to the system.

An equipment inspection tracking system and method for radiopharmaceutical personal protective equipment which has a read-only RFID tag and a database management system that allows a user to track, update, review and report a record of standard tracking and compliance history information. The system and method are customizable and can be used for large and varied quantities of radiopharmaceutical personal protective equipment. The system and method allow access by safety officers and compliance inspectors for required regulatory reporting. The system and method are accessible through a web browser or mobile application.
摘要:
An integral roof and gable edge assembly includes a metal or plastic sheet formed with positioning surfaces to facilitate slate tile installation by relatively unskilled roofers. The roof and gable assemblies include one or more hooks for holding one or more slate, ceramic or other similar roofing tiles in fixed position along the eaves and/or gables of a roof. A lift arm can be provided on the roof assemblies to replace cant strips and simplify tile installation. Tiles can be easily installed without nailing through the tiles.
摘要:
A tool is provided that is capable of friction stir processing, friction stir mixing, and friction stir welding of high melting temperature and low melting temperature materials, wherein the collar is now divided into at least an inner and an outer collar coupled to the shank and the FSW tip, wherein new thermal barriers enable expansion of the inner collar to be directed inward to thereby create compression on the FSW tip instead of allowing the FSW tip to become loose in the tool at elevated temperatures.
摘要:
The naphthyridine derivatives of formula (I) a and method of combating or controlling phytopathogenic fungi which comprises applying the compounds of formula (I) to a plant, to a seed of a plant and to the locus of the plant.
摘要:
The present invention relates to substituted pyrimidine derivatives of as well as N-oxides and agriculturally acceptable salts thereof, and their use to control undesired plant growth, in particular in crops of useful plants. The invention extends to herbicidal compositions comprising such compounds, N-oxides and/or salts as well as mixtures of the same with one or more further active ingredient (such as, for example, an herbicide, fungicide, insecticide and/or plant growth regulator) and/or a safener.
摘要:
A new control variable is introduced, that when combined with previous dependent control criteria on other variables results in a control program that can create a superior weld while minimizing wear on the FSW tool, wherein the tool repeatedly experiences the same thermal and mechanical loading within specified control windows during every repeated weld sequence because flow stresses and tool loads are driven by temperature, and dependent control loops account for differences in material and heat that is transferred at different rates in varying locations throughout a friction stir weld.
