Abstract: An airfoil (400) has a plurality of spaced apart, U-shaped troughs (408,410) in either or both its suction or pressure surface (402,404) in the trailing edge region. Each trough (408,410) extends in a direction generally parallel to the bulk fluid flow in its vicinity near the airfoil surface and has an outlet at the trailing edge (406). The troughs (408,410) increase in depth from their inlets toward their outlets, the maximum depth being no more than half the trailing edge thickness. The troughs (408,410) are spaced apart, sized and configured to flow full over their entire length and to cause fluid to flow into the space immediately behind the trailing edge (406), thereby reducing base drag.

Abstract: Contaminated portions of bulk material are removed from a flow of bulk material with the aid of a flow or drop pipe in a casing that is movable back and forth between a discharge position and a normal flow position. The flow or drop pipe is equipped with baffle plates or bends for sufficiently retarding the free flow of the flowable bulk material to enable a detector and control mechanism to respond to the presence of contaminations and to then move the casing for the discharge of a contaminated portion of bulk material. The movement of the casing of the flow pipe assures that a slide gate or a portion of the casing closes the upper inlet to prevent the further flow of bulk material when the casing is in a discharge position. Due to the retardation of the free flow of the bulk material, it is possible to construct the apparatus with a substantially shorter structural height than was possible heretofore.

Abstract: A microwave crossover ( 20) by which an electromagnetic wave can crossover from one waveguide to another waveguide is formed completely within a planar structure having two hybrid couplers (28, 30) arranged in tandem with output ports of the first coupler connected to input ports of the second coupler. Each coupler is formed of an electrically conductive housing (40) and two electrically conducting bars (56, 58) disposed therein and insulated therefrom. The bars are disposed in a common plane and are equally spaced from top and bottom walls of the housing. A central portion (52) of each bar is angled relative to end portions of the bars to permit a crossing over of the bars at the central portions thereof. Each of the central portions is formed with a notch which engages with the notch of the other bar while maintaining a gap therefrom, the notches permitting the crossover to occur in the foregoing plane. Ends of the bars protrude through openings in the housing in the form of coaxial transmission lines. The crossing (54) of the bars has the effect of a twist of central conductors (32) of the coaxial lines resulting in a relocation of the ports of the coupler such that the two input ports (36, 38) are on an input side of the coupler, and two output ports (44, 46) are on an output side of the coupler. This arrangement of the ports permits the connection of two couplers in tandem to provide for the planar configuration of the microwave crossover.

Abstract: Non-human mammalian cell lines which express the major human rhinovirus receptor protein. The cell lines are prepared by gene transfection of human DNA, such as HeLa cell DNA, into non-human mammalian cells, such as mouse cells. Primary transfectants can be transfected into further non-human mammalian cells to provide secondary transfectants. Cloning of secondary transfectants yields cell lines that exhibit enhanced expression of the surface receptor protein. The transfectant cell lines provide a means for cloning the major human rhinovirus receptor protein gene and immunogens for producing antibodies, particularly monoclonal antibodies, against the receptor protein. A general method for screening drug candidates for their ability to block ligand binding to a human cell surface receptor protein is also provided.

Abstract: In the conventional process for the production of a double-oriented electrical steel sheet, the preparation steps are complicated and the manufacturing cost is very high. Nevertheless, the magnetization characteristic B₁₀ is lower than 1.85 Tesla and the final sheet thick­ness cannot be reduced below 0.30 mm. According to the present invention, by strictly controlling the secondary recrystallization temperature and performing the third cold rolling in the same direction as the rolling direction of the first cold rolling, the magnetization characteristic B₁₀ can be increased above 1.88 Tesla and the final sheet thickness can be reduced to 0.20 mm. Moreover, a double-oriented electrical steel sheet having an excellent shape (flatness) and a much smaller thickness deviation in the longitudinal direction of the product can be produced on an industrial scale. There­fore, this product can be effectively used as a core material of a large-size rotary machine or in a small-­size static magneto-electronic device.

Abstract: An error correction circuit (16) corrects errors in the thermometer code (T₁-T₇) developed by a parallel or "flash" analog-to-digital converter (10). The error correction circuit employs plural similar bit exchange modules (34) of which each includes a 2-input OR gate (46) having common inputs (48 and 50) that constitute the inputs of the bit exchange module. The output (52) of the AND gate and the output (54) of the OR gate constitute the outputs of the bit exchange module. The bit exchange modules receive the digital-to-analog converter thermometer code and are interconnected to correct errors therein resulting from the presence of more than one transition between different logic states for adjacent bits in the thermometer code. The error correction circuit manipulates the thermometer code bits to provide a corrected thermometer code (T 1C -T 7C ) that has only one transition between different logic states for adjacent bits thereof.

Abstract: An actuator has a pilot valve incorporated in a piston thereof which is slidably disposed in a cylinder tube, the piston having first and second piston lands slidably disposed in first and second coaxial cylinder chambers. A spool valve body has first and second spool lands slidably disposed in an inner hole in the piston. When the spool valve body is moved in one direction, a first axial passage in the piston communicates with a pressure sink through a first return port which is opened by the first spool land, and a second axial passage in the piston communicates with a portion of the inner hole in front of the second spool land through a second supply port which is opened by the second spool land. When the spool valve body is moved in the opposite direction, the second axial passage communicates with the pressure sink through a second return passage which is opened by the second spool land, and the first axial passage communicates with a portion of the inner hole in front of the first spool land through a first supply port which is opened by the first spool land. The spool valve body is movable under a differential pressure between two inlet ports. The pilot valve can amplify the operating force on the piston even if the difference between applied input oil pressures is small. In addition, the actuator is compact in size.

Abstract: A computer workstation including a processor, one or more input/output units, such as disk devices or network interfaces, a program memory and a video memory which contains video information displayed on a video monitor. An arbitration circuit selects among the processor and input/output units for transfers to and from the program memory and video memory. A master control circuit controls timing of transfers to and from the program and video memories, and periodically enables video update transfers of video information from the video memory to video control circuits, which control the video monitor. While a video update is in progress, the master control circuit holds off other transfer request of the processor and input/output units with the memory. The program memory stores interrupt vectors. In response to interrupt requests from units which require interrupt service, the master control circuit interrupts the processor. When the processor acknowledges the interrupt, the master control circuit enables the transfer from the memory to the processor of the interrupt vector associated with the highest priority interrupt.

Abstract: A shutdown seal is provided in a pump for activation to prevent passage of fluid along a shaft relative to a fluid-containing housing of the pump through which the shaft extends. The shutdown seal is an annular member having a mounting flange and a sealing collar. The mounting flange is attached to the housing, and the sealing collar is disposed about the shaft. The annular member is constructed of shape memory metal material which below its transition temperature has an expanded configuration in which its annular sealing collar portion is spaced from the shaft so as to define a deactivated unsealed condition of the shutdown seal. On the other hand, above the transition temperature of the material the annular member has a contracted configuration in which its sealing collar contacts the shaft so as to define an activated sealed condition of the shutdown seal. In one embodiment, the annular member of the shutdown seal forms a stationary part of a slip joint secondary seal coupled between the housing and shaft. In another embodiment, the annular member of the shutdown seal forms a hollow shell attached to the interior of a stationary part of a slip joint secondary seal coupled between the housing and shaft.
