摘要： An inertia insensitive disconnectable drive linkage connects a power operator to a swinging door and comprises a door bracket fixed to the door and an arm operator pivoted thereto. A latch positively locks the operator arm to the bracket during normal powered swing of the door. A cam on the door frame releases the latch when the door is swung beyond the door closed position in the opposite direction of opening during emergency operation.

摘要： A hopper car discharge section may be wide at the top and narrow at the bottom. Outflow is controlled by closure members, at least one of which is movable. The closure members come together to a closed condition or position for retaining lading. When apart, in an open position or condition, lading may be discharged. A seal member or seal member assembly is mounted to one or both of the closure members. When open, the seal member or seal member assembly lies substantially flush with, or shy of, the slope of the surface of the closure member. When closed, the seal member may be self-energizing, in the sense that as lading is added the seal may tend to seal more tightly. The seal assembly may include a cantilevered spring that presents a land to the opposed closure member, and a fulcrum, over, or across, which the spring is cantilevered, such that pushing down on one end of the spring may tend to cause the other end to flex upward. The fulcrum may also be cantilevered outward from the slope sheet of the closure member to which the seal assembly is attached. The discharge section may be robustly reinforced to discourage deformation.

摘要： A liquid-crystal display preferably eighteen lines of forty characters each, is mounted in a case. The temperature of the display medium is held within operating limits for the display--notwithstanding ambient temperature and humidity variations over generally normal ranges for at least the temperate zones, and even if the display unit receives direct sunlight. The unit works outdoors, at temperatures to at least 46.degree. C. (115.degree. F.) as well as in buildings with no temperature control. This is accomplished by use of a shading hood, and a window (preferably unperforated polycarbonate, curved, upward-and-outward-concave, and cylindrical-segment) that reflects to a viewer only light from the hood underside. No ventilating fan, plenum or other ventilating opening is needed. A circuit-board-mounted temperature sensor controls the contrast-adjusting voltage of the display--using data in a digital-memory "look up" table. A heater is preferably provided, also temperature-controlled. The entire unit can be flush-mounted in a wall without disrupting operation. Visible glare arising in reflection at the window is reduced by the hood-and-window combination, without need for any antireflection coating on the window.

摘要： A local communication apparatus (e.g., a modem) is arranged to detect when a remote communication apparatus desires to switch from the data mode and enter a command/control mode. To accomplish mode switching, the remote apparatus sends a scrambled escape pattern, scrambled using a proprietary polynomial, over the data channel. After detecting the escape pattern the local apparatus switches to the command/control mode. In this mode, the remote and local apparatuses communicate using the proprietary scrambler/descrambler polynomial.

摘要： A liquid-crystal display, preferably twenty-five lines of eighty characters each, is mounted in a case. The temperature of the display medium is maintained within operating limits for the display--notwithstanding ambient temperature and humidity variations over generally normal ranges for at least the temperate zones, and even if the display unit is placed to receive direct sunlight. The unit works outdoors as well as in buildings that lack temperature control. This is accomplished preferably by circulating air from outside the case through a space between the display face and an unperforated protective polycarbonate window. Intake and exhaust plena are long and narrow enough to deter access to the display and thus vandalism; however, the plena are straight and sufficiently free of obstructions that the fan can be a very small, low-power, quiet unit. A temperature sensor controls the fan, and also the contrast-adjusting voltage of the display--based on data in a digital-memory "look up" table. A heater is preferably provided, also temperature-controlled. The plena face downward so that the unit is not sensitive to rain, and the entire unit can be flush-mounted in a wall without disrupting system cooling. Visible glare arising in reflection at the window is reduced by an antireflection coating on the window.

摘要： To minimize the weight of a magnetic tape recorder chassis and cabinet assembly, a wire frame chassis (18) carrying printed circuit board guides (20) and connectors (22) is mounted to one side of a sand cast bezel (24), and polyurethane wall panels (16) are secured to the wire frame. A cabinet cover and underlying tape transport assembly are hinged to the bezel to enable pivoting away from the wire frame, exposing circuit boards for servicing. The "open air flow" characteristic of the wire frame chassis (18) helps cool critical electrical components.

摘要： A hopper car discharge section may be wide at the top and narrow at the bottom. Outflow is controlled by movable closure members. The hopper car has a plurality of hoppers of which two hoppers share a common ridge assembly. The ridge assembly forms a common mating and fit up location for the upper margins of the slope sheets of two lengthwise adjacent hoppers. The ridge assembly includes an horizontal center section and two end plates that angle upwardly outboard toward the top chords of the sidewalls. The ridge assembly stands proud of the upper margin of the respective adjacent slope sheets. A gusset is mounted between the adjacent slope sheets below the ridge plate such that the slope sheets and gusset form a reinforcement tube running across the car, the end plates forming the stems of a vertical T-section attached to the sidewall and overlapping the top chord.

摘要： A rail road freight car truck, which may be a Barber S2HD truck or other kind of truck, has a truck bolster and a pair of side frames, the truck bolster being mounted transversely relative to the side frames. The sideframes are mounted on a pair of wheelsets. The bolster may be resiliently sprung and may have friction dampers. Either the friction dampers or the sideframe column wear plates may have a non-metallic wear plate, or wear surface, which may be replaceable, and which may tend to exhibit non-stick slip, or reduced stick slip behaviour in use. Bearing adapters may be mounted on the bearings of the wheelsets, and resilient pad members may be mounted on the bearing adapters. The pedestal seats may sit over the resilient pads. There may be a discontinuity in the vertical load path between the pedestal roof and the bearing. The discontinuity in the vertical load path may tend to shed a portion of the vertical load to either side of the top rollers of the bearing races to a greater extent than if the vertical load path discontinuity were not present.
