Abstract: AN OPEN CENTER HYDRAULIC SYSTEM   Abstract of the Disclosure An open center hydraulic system is disclosed which contains a primary work circuit and a secondary work circuit.  A fixed displacement pump is fluidly connected between a reservoir and the primary and secondary work circuits for supplying pressurized fluid thereto.  The primary work circuit includes a control valve which regulates fluid flow from the pump to a primary hydraulic function and which includes a feedback mechanism connected thereto.  The secondary work circuit also includes a manually operable control valve for regulating fluid flow from the pump to a secondary hydraulic function.  A priority valve is connected between the pump and the secondary work circuit and is movable between an open and a closed position to regulate the pressure of fluid discharged by the pump.  Pressurized fluid from the primary work circuit is conveyed through a load signal line to the priority valve such that the pressurized fluid will urge the priority valve towards the closed position thereby assuring that adequate fluid pressure is available from the pump to the primary work circuit.  The system also includes a control valve for sensing pressure variations between the fluid discharged from the pump and fluid present in the load signal line.  This valve controls fluid flow out of the primary hydraulic function, via the load signal line, when the pressure of the fluid discharged by the pump is less than the pressure of the fluid in the load signal line and thereby essentially eliminates kickback from the primary control valve.

Abstract: Abstract The invention is directed to an arrangement for controlling the intake air for the carburetor of a hand-held portable tool such as a motor-driven chain saw or the like.          During winter operation, the cooling air that is heated by the engine cylinder is carried through a pass-through opening to the carburetor.  During summer operation the pass-through opening is blocked by a slide that is pivotally mounted on a pivot axis.  The slide selectively opens or closes the pass-through opening and is configured as a deflector which, in its open position baffles the heated cooling air from the engine cylinder and guides it toward the carburetor.

Abstract: ABSTRACT OF THE DISCLOSURE          A  temperature detection pyrometer       for determining the temperature of a turbine blade includes means      for detecting radiation reflected and emitted from the turbine blade.   The reflected radiation  is  a  result  of  flame  and  hot  carbon particles rather than the emission representing the blade temperature.  The radiation is divided into two channels        , each of which detects radiation in different,  but  preferrably  overlapping  wavelength bands,   to  detectors            providing   currents proportional  to  the  radiation  intensity  in  the respective channel.  The signal from one channel is weighted with respect to the signal from the other by a constant (k)  that is equal to the ratio of the  radiation  in  the  two  channels  which  is  the attributable   to   the   reflected   radiation.    The difference between the signals,  after weighting the one signal by the constant  (k)  provides  an  output that is a function of blade temperature only so the blade temperature may be obtained from a calibration curve or a look-up table.
