摘要： Disclosed herein is a sliding vane pump for providing positive displacement of a fluid such as water. The pump comprises a pump assembly having a housing with a fluid inlet and a fluid outlet formed therein, a lining member received in the housing and defining a substantially cylindrical inner surface and a rotor arranged inside the lining member to rotate about a rotational axis. The rotor defines a substantially cylindrical outer surface such that the inner surface of the lining member and the outer surface of the rotor define a working space therebetween, the working space having a radial cross-sectional area which varies about the rotational axis. The pump assembly also comprises a plurality of vanes received in substantially radial slots formed about the outer surface of the rotor. Each of the vanes is arranged to slide in the radial direction with respect to the rotor such that an outer edge of the vane contacts the inner surface of the lining member, thereby dividing the working space into working chambers. In use, rotation of the rotor draws the fluid from the fluid inlet into the working chambers and ejects the fluid from the working chambers into the fluid outlet. The vanes are formed of a carbon graphite or ceramic material and the rotor is formed of a ceramic material, which provides reduced thermal expansion compared to convention materials such as stainless steels. A base portion of each of the slots of the rotor is enlarged and has a rounded cross-sectional shape. The pump assembly further comprises a strainer assembly received into an opening in the housing and extending across the fluid inlet for filtering particulate matter from the fluid. The strainer assembly comprises a thermal sensor for sensing a temperature of fluid passing through the fluid inlet.

摘要： The invention provides apparatus for controlling a search lamp using a wireless transmitter and receiver. The transmitter responds to user inputs by providing a wireless digitally encoded modulation signal containing information indicating at least one operation in a set of operations the search lamp is able to perform. The receiver responds to the wireless digitally encoded modulation signal by providing a control signal for controlling the functionality of the search lamp. The functionality may include, for example, moving the search lamp left/right and/or up/down, a sweep on/off @ +/−45 degrees; X/Y/Z movement (Z when motors run simultaneously); Diagonal sweep (motors run simultaneously); Fast/Slow sweep (50%/100%). The transmitter and receiver are programmable to communicate on a unique 16 bit digital code setting that provides about 65K different code settings, which may also include a random code setting.
