摘要： A trailer sensor (83) for use on a retractable railcar trailer hitch (1) is disclosed. The hitch has a hitch head (3) for capturing a kingpin (K) of a trailer (T), a locking mechanism (35) for latching the hitch in its erect position, and a manually operable release mechanism (67) for retracting the hitch. A movable sensing element (85) carried on the hitch head senses the presence or absence of a trailer. A rod (93) moves the sensing element in response to operation of the release mechanism. If a trailer is supported by the hitch, the assembly blocks movement of the sensor and prevents retraction of the hitch. If no trailer is supported by the hitch, the sensing element allows the release mechanism to unlock the hitch so it can retract.

摘要： A fixed sill includes a pair of lower, outwardly extending fixed sill flanges. A generally vertical longitudinally extending support plate is integrally connected to each fixed sill flange on each side of the fixed sill. A sliding sill support is rigidly connected to each support plate. The sliding sill support includes a horizontal inwardly extending portion that also extends longitudinally inboard. The sliding sill support is located slightly below the fixed sill flange. A pair of low friction wear plates are adopted to be slipped in place upon each sliding sill support. The low friction wear plates include horizontal body portions on each side of the fixed sill upon which the sliding sill rides in moving back and forth. Each wear plate includes "U" shaped end portions which wrap around in the inner and outer ends of the sliding sill support. The wear plate is made of resilient material having a low coefficient of friction with steel and good strength in compression to withstand the load of the sliding sill.

摘要： A control system (1) for bleeding air into the high speed and low speed fuel circuits (HS and LS) of a carburetor (C) mounted on an internal combustion engine (E). The carburetor has an air passage (AP) to which fuel is delivered to mix with air and form a mixture combusted in the engine. Air is directed from an air inlet (9) through a first air flow path (5) to the high speed fuel circuit and through a second air flow path (7) to the low speed fuel circuit. An isolator (57) prevents crossover of air from one air flow path to the other. A flow control (77) opens and closes the first and second air flow paths, the flow control opening and closing both air flow paths substantially simultaneously.

摘要： Apparatus for automatically controlling the idle speed of an internal combustion automobile engine. A sensor senses the operating speed of the engine and develops an electrical signal representative thereof. Movement of a carburetor throttle valve from an open to a substantially closed position is sensed and an electrical signal indicative thereof is generated. Closure of the throttle valve indicates the engine is operating at idle. A controller is responsive to the second electrical signal to process the electrical signal from the sensor and generate an electrical control signal. The controller processes the electrical signal from the sensor means in accordance with a predetermined format based upon a transfer function derived for the engine. An electromechanical device is responsive to the control signal for moving the throttle valve to a desired position at which engine idle speed is a preselected speed determined in accordance with the transfer function.

摘要： In accordance with the present invention an open top railway car is provided in which the car body is divided longitudinally into at least two body sections having opposite ends which are pivotally mounted on vertically extending supports attached to a car underframe. The body sections include respective transversely spaced side walls, at least one end wall, and bottom walls having inner edges which abut and/or overlap in closed position to define the bottom of the car. To achieve increased volumetric carrying capacity, the bottoms are horizontal and extend outboard of the wheels. Each of the body sections is pivotable from the closed position to an open position in which the inner edges of the bottom walls are spaced apart to allow discharge of lading between the rails. An energy saving unloading system is also disclosed for unloading the cars.

摘要： A trailer hitch head or fifth wheel is disclosed including a pair of jaws which engage the kingpin of a trailer to hold the kingpin in place. The jaws are held in closed position by a locking member which is biased to the engaged position by at least one stiff spring. A linkage engages the locking member to move the locking member to open position against the bias of the stiff spring. The linkage may be manually or automatically activated. A one-way kingpin gate is located in the front portion of the fifth wheel. The linkage engages an actuator which automatically engages the one-way gate and pivots the same to open position allowing exit of the kingpin. Preferably the linkage is automatically activated by a bumper bar linkage in a tractor operated hitch, and also may be manually activated by the operator. Optionally, a manually operable handle is provided including a keeper or projection which engages a slot in the locking member in open position to hold the locking member in open position.

摘要： In accordance with the present invention a hatch cover opening and closing assembly is provided including a locking handle having a yoke pivotably mounted about a vertically extending shaft located in the center portion of the cover. The shaft extends downwardly through a guide which depends from the cover. The guide includes at least one generally vertical indexing slot. Below the cover a laterally extending pin and a plurality of radially extending locking arms are attached to the shaft. A plurality of locking lugs are mounted on the internal surface of the coaming. The shaft is rotatable by the handle to move the locking arms into and out of engagement with the locking lugs. However the pin must be located within the indexing slot to move the locking arms vertically into engagement with the locking lugs. When the shaft is rotated so that the pin is located out of the slot, but in engagement with the guide, the handle may be used to pivot the cover about a hinge into open position. Preferably the locking arms comprise leaf springs when in engaged position with the locking lugs. The yoke on the handle is preferably formed in the shape of an arcuate cam surface whereby in closed position the yoke assumes an overcenter position on the cover, urging a seal on the cover into engagement with a lip on the coaming, against the bias of the leaf spring locking arms.

摘要： A carburetor for an internal combustion engine has an idle or low speed system in which air is bled into the idle fuel passage. An air bleed valve member controls the amount of air flow through an air bleed port for the idle fuel passage and a diaphragm operated control is connected to the air bleed valve member to control the movement of the valve member. The diaphragm operated control has an air chamber on one side of the diaphragm and a vacuum chamber on the other side of the diaphragm with a restricted opening between the air and vacuum chambers. Upon a rapid engine deceleration to an idle position, the air bleed valve member is moved to a position to provide maximum air flow to the idle fuel passage for a limited period of time until the pressure is equalized between the vacuum chamber and the air chamber through the restricted opening. Such an arrangement permits fuel which has previously condensed on the walls of the manifold to be leaned for a short period of time after a rapid increase in intake manifold vacuum which results from rapid engine deceleration to an idle position.

摘要： A ball valve structure having a ball member with upstream and downstream circular edge portions defining the entrance and exit ports of the ball member which ports are positioned adjacent the upstream and downstream seat members. Each of the circular edge portions has a generally arcuate groove or indentation therein positioned on the circumferential segment of the respective circular edge portion initially clearing the adjacent associated seat member upon rotation of the ball member from a fully closed position thereby increasing substantially the flow area exposed to fluid flow upon the initial opening of the valve member.
