Abstract: A conveyor belt that uses cleats to more effectively transfer materials through a curvilinear structure into a deposit receptacle. The cleats are either in the form of a notched cleat or slit cleat. In both forms, the cleat is adaptable to conforming from a flat conveyor belt to a curved conveyor belt within the curvilinear structure. The resulting cleat on the conveyor belt provides increased support for the prevention of backflow of materials during transportation of the material:; through the curvilinear structure.

Abstract: An interface between the end of a bolster and a side frame column for a three-piece railcar truck assembly is disclosed. The bolster and side frame have several pairs of facing stop surfaces at the interface. Each pair of facing stop surfaces are at two different spacings: one spacing is close, with a small gap between the stop surfaces; another spacing is greater than the first. The second spacing allows the side frame to pitch with respect to the bolster transverse axis. The bolster stop surfaces may be the lands inboard and outboard of the friction shoe pockets. The lands may be shaped so that there is a raised warp control portion or surface and one or more relief portions or surfaces, the warp control portion extending farther laterally than the relief portions. The warp control portion is used to maintain the truck in a square relationship, and the more loosely spaced relief portions allow for side frame articulation as the truck traverses track at different elevations. The raised warp control portions and reliefs may alternatively or also be formed on the side frame lands or wear plates.

Abstract: An inverted boxhorn antenna array (10) comprising a power divider (11) that is constructed from a single metal piece and a flat metal sheet that is fastene d to a rear surface of the power divider. The power divider is fabricated usin g a variety of waveguide junctions (14-16) coupled between substantially identical inverted boxhorn subarrays (20). The junctions includes a central magic tee junction (14) for coupling energy from an input port (12a) into th e power divider. Alternating folded shunt and folded series tee junctions (15,  16) are used to transfer power coupled by way of the central series junction  to the inverted boxhorn subarrays. Specially dimensioned folded shunt and series tee junctions are used in the inverted boxhorn subarrays. Waveguide matched loads (27) are bonded in waveguides between each of the inverted boxhorn radiators of the subarrays. A fully functional antenna assembly (30)  includes a radome cover (18b), a quadrature correction plate (18a), and a twist polarizer (18c) disposed in front of radiating elements (13) of the inverted boxhorn antenna array.

Abstract: A directional induction logging tool is provided for measurement while drilling. This tool is preferably placed in a side pocket of a drill collar, and it comprises transmitter (16) and receiver (18, 20) coils and an electromagneti c reflector (38). The reflector (38), which may be a lyer of highly conductive material placed between the coils and the body of the drill collar (12), serves to focus the electromagnetic fields generated and sensed by the tool in the direction away from the reflector (38), thus providing a directional respons e to formation conductivity with a relatively high depth of investigation. In preferred embodiments of the invention, magnetically permeable cores are placed within the coils to concentrate the magnetic fields that pass through them. Circuitry is described for balancing the mutual inductive coupling of the coils by injecting a direct current signal through one or more of the coils, which alters the magnetic permeability of the core material. The magnitude of the direct current required to achieve a balanced condition may be derive d from the quadrature phase component of the return signal. Circuitry is also provided for generating a transmitted signal and for processing the return signals, including digital-to-analog conversion circuitry for providing digital data for transmission to the surface. This tool may be employed to provide real-time directional conductivity information that may be used to detect an d follow bed boundaries in geosteering operations.

Abstract: A record carrier (1) is described comprising a servo track (4) indicating an information track (9) intended for recording information blocks represented by marks having lengths expressed in channel bits, which servo track (4) has a periodic variation of a physical parameter.  The periodic variation is modulated for encoding record carrier information, such as addresses. The modulation is a bi-phase modulation in which a data bit of the record carrier information is encoded by a first predetermined number of variations of a first phase followed by the same number of variations of a second phase inverse to the first phase. A  recording and/or playback device has a demodulator for retrieving data bits of the record carrier information from a first predetermined number of variations of a first phase followed by the same number of variations of a second phase inverse to the first phase.
