Abstract: Columnar Grain Ceramic Thermal Barrier Coatings on Polished Substrates Abstract A coated article and method for producing the coated article are described.  The article is coated with a system which provides protection against oxida-tion and corrosion and which significantly reduces the substrate temperature.  An MCrA1Y layer is applied to the article to be protected and a columnar grain ceramic is applied by vapor deposition to the MCrAlY coated article.  An alumina lyaer which exists between the MCrAlY layer and the columnar ceramic layer provides for the adherence of the columnar layer to the MCrAlY layer.  An important feature of the invention is that the interface between the MCrAlY layer and the alumina layer has a low surface roughness and this greatly improves the columnar ceramic layer adherence.

Abstract: ABSTRACT:         A differential load circuit which can be used as a load for a differential pair and which comprises a first, second, third and fourth field-effect transistor of the same conductivity type, whose gate electrodes are interconnected.  The source electrodes of the first and second transistors are connected to a first power supply terminal and the drain electrodes of the third and fourth transistors to a second power supply terminal via quies-cent current sources.  A first input terminal is con-nected to the interconnected source electrode of the third transistor and the drain electrode of the first transistor and a second input terminal is connected to the interconnected source electrode of the fourth trans-istor and the drain electrode of the second transistor, whilst an output terminal is connected to the drain elec-trode of the fourth transistor.  The first and second input terminal may be coupled to the drain electrodes of a differential pair of transistors. Biasing means, which are coupled to the gate electrodes of the four transis-tors, supply such a voltage to the gate electrodes that the common-mode drain currents of the third and the fourth transistor correspond to the currents supplied by the quiescent current sources.

Abstract: ABSTRACT  OF  THE  DISCLOSURE        Apparatus for drawing taut a cover sheet over a box opening such as a truck box or walled building of rectangular plan form provides an external socket in a longer sidewall for captively storing a roller when the sheet,  which is tangentially attached to the roller,  is fully unwound in covering the opening to provide an external overhanging sheet portion disposed at a rain-shedding angle of 45° or greater,  a torque being applied to the roller to maintain a seal along the top outer edge of the sidewall.     When the roller is given a fractional turn additionally in the unwinding direction as by a swivellable drive shaft having a handle,  it automatically locks under a lateral flange portion of the socket against the sidewall.  Either an integral socket in a metal sidewall or a supplemental bar or angle section may comprise the socket.  The drive shaft maintains sheet tension when it is engaged in a wall-mounted keeper bracket.  A tensioning cord engaged by rings on hubs extending from the roller ends is housed in a tube under the socket to bias the roller toward the unwound position.  When the roller is turned in the winding-up direction it automatically unlocks and swings out from the socket, then traverses the sheet roll to the opposite side of the box to stored position.

Abstract: Abstract of the Disclosure A windpower system includes a support and a turbine having a shaft rotatively mounted to the support.  The turbine has variable pitch blades whose pitch is controlled by the differential motion of a rotary control shaft coaxial with the turbine shaft and the turbine shaft itself so that the blade pitch can be varied by a stationary motor without requiring any slip rings or other such wear-prone couplings.  In the event of a power failure, rotary motion of the control shaft is prevented so that the turbine blades are feathered solely due to the force developed by the rotating turbine. Also, if the turbine is used to generate electrical power, an induction generator coupled to the turbine shaft is employed whose shaft speed is indicative of generator output power.  Accordingly, generator speed is monitored and used to control the pitch of the turbine blades so as to maintain generator output power at the maximum value when wind speed is below the machine's rated wind speed, and no more than rated output power when wind speed exceeds rated wind speed.
