The Use of Chemical Methods and Magnetic Field in Conditioning and Dewatering of Digested Sewage Sludge This study verified the possibility of sludge conditioning before dewatering using a combination of factors such as iron coagulant, polyelectrolyte, and the magnetic field generated by a solenoid. It...
I would like to automate a section of the layout so that a mine switcher takes different routes each time it passes through a turnout. Here is the situation, there is a 12 foot switchback up to a mine location. There is a gargraves 042...
Method for locating an inaccessible object having a magnetic field generating solenoid A tilt sensor may be provided to indicate if the axis of the solenoid is not horizontal, to enable axial radial directions to be determined.doi:US5917325 ARoyston SmithUSUS5917325 1996年3月19日 1999年6月29日...
A device and method for detecting the running direction of an automotive vehicle includes terrestrial magnetic field direction detection, vehicle steering angle detection, and response to the signals of these detectors for producing the vehicle running d
(1)) for exciting the exciting winding 1D at the frequency f. The magnetic field in the magnetic core 1C changes with the sum (H+h) of the horizontal component H of the earth magnetism applied to the geomagnetic field sensor 10 and the horizontal component h of the distortion of the ...
2) electro magnetic proportional multi-way direction valve 电磁比例多路换向阀 例句>> 3) directional control valves 多路换向阀 1. Flow simulation software was adopted to emulate the flow field of bridge flow passage in directional control valves. 采用流体仿真软件对多路换向阀的桥路进行流场仿真,...
My invention relates to radio direction finders, and more particularly, to that type of direction finder that automatically indicates the deviation in bearing to the right or left of the desired direction. This application is a continuation-inpart of my co-pending application Serial No. 43,189,...
As a reversible motor for moving the signal arm to and from operative extended or projected position, we provide a double solenoid motor that is very similar in character to that of our above identified co-pending application. This motor is comprised mainly of longitudinally spaced flat solenoids...
