Abstract: A stop bar for use in a refuse collection vehicle with a rear hopper having an opening defined by sidewalls, an upper edge, and a loading sill. The stop bar includes an elongated bar with support arms secured to each of its ends. The support arms are pivotally mounted to the sidewalls of the hopper and two stops are provided for limiting the pivoting movement of the stop bar between a first, non-engaged position and a second, fully engaged position.

Abstract: A pipe cleaning tool (10) comprises a cleaning assembly (12) and a hollow riser (14) received over the assembly (12). The cleaning assembly (12) defines and axis of rotation and includes a drive shaft (16) for rotating the assembly about the axis and resilient blades (18) operatively coupled with the drive shaft (16). The blades (18) include first and second edges (24, 26), and are movable between contracted and expanded conditions. The riser (14) is configured for axial movement relative to the cleaning assembly (12) between first and second positions for shifting the blades (18) between the contracted and expanded conditions. The tool (10) is configured for cleaning pipe prior to joining pipe.

Abstract: The apparatus for winding optical fiber on a bobbin in axially compact coils includes a bobbin mount reciprocably driven along the fiber deployment axis, a winding arm for receiving optical fiber being fed along the deployment axis, and a supply reel for feeding optical fiber along the deployment axis with the reel being mounted on a twist arm, with the reel axis orthogonal to the deployment axis, for rotating the reel a preselected amount for each turn of the winding arm. An optical time domain reflectometer continuously monitors optical signal attenuation through the free start end of the fiber, and an optical scanner continuously scans the formed coils for the presence of gaps and overlaps. A controller is used to automatically stop, rewind, and adjust the winding apparatus when excessive signal attenuation, gaps or overlaps are detected.

Abstract: A method and apparatus for taking up elongate, flexible communication lines such as wires and optical fibers for simulating the payout of such communication lines from rockets, missiles, aircraft or the like during launch and flight comprising a rotatable flywheel mounted on a base, a rotatable take-up drum having a weight substantially less than the flywheel and having a peripheral winding surface mounted on the same base, a clutch mechanism engageable to render the take-up drum rotatable with the flywheel, a driver source for rotating the flywheel, attaching one end of a communication line to the peripheral winding surface of the take-up drum, rotating the flywheel using the driver source until the desired rotational velocity is attained, and engaging the clutch mechanism to transmit the rotational momentum of the flywheel to the take-up drum in order to impart tangential acceleration and final tangential velocity at the peripheral surface of the take-up drum in a manner simulating the acceleration and velo

Abstract: A pressure differential bypass sensor switch with thermal lockout that utilizes change in position of a permanent magnet carried by a reciprocable piston responsive to pressure differential in a fluid system to actuate a magnetically actuatable electrical switch. Opposite sides of the reciprocable piston are exposed, respectively, to high pressure and low pressure sides of a filter located in a fluid circulating system. The reciprocable piston is normally positioned at the high pressure side of a passage in which it reciprocates, due to biasing by a spring acting on it from the low pressure side of the passage. As the filter becomes clogged, the pressure differential across it and, therefore, across the reciprocable piston will increase. The bypass sensor is calibrated so that a maximum allowable pressure differential in the fluid system will drive the reciprocable piston to the low pressure side of the passage.

Abstract: A temperature compensating differential pressure indicating device having a lock-out feature requiring internal reset after actuation. The differential pressure responsive indicating device includes a case having an internal chamber and a piston reciprocably and sealingly disposed in the internal chamber. A piston follower is also reciprocably disposed in the internal chamber and abuts against the piston. A first biasing element biases the piston and the piston follower in a first direction while a second biasing element biases these components in the opposite direction, the second biasing element being weaker than the first biasing element. The piston is displaceable in response to the pressure differential between an inlet pressure and an outlet pressure. A shape memory alloy temperature responsive abutment permits the piston follower to move together with the piston at or above a predetermined temperature, while preventing motion of the piston follower below the predetermined temperature.

Abstract: An excessive pressure differential indicating device for use with a filter in a liquid circulating system. The device has a reciprocable piston that reciprocates between a high pressure location, when the pressure differential is not excessive, and a low pressure location, when the pressure differential is excessive. The device has an indicator button with a magnetically conductive element, and the button is retained in a non-indicating position when the reciprocable piston is at the high pressure location by magnetic attraction between a permanent magnet carried by the reciprocable piston and the magnetically conductive element, a spring being provided to bias the indicator button to an indicating position when the reciprocable piston moves with the permanent magnet away from the indicator button to the low pressure location.

Abstract: A pressure differential bypass sensor switch that utilizes the change in piston of a permanent magnet that is carried by a reciprocable position to actuate the switching element of an axial travel switch by the change in magnetic forces that act on the switching element as a result of the change in position of the reciprocable piston and the permanent magnet. Opposite sides of the piston are exposed, respectively, to the high pressure and low pressure sides of a filter in a liquid circulating system, and the piston is normally positioned at the high pressure side of a passage in which it travels by a spring that acts on it from the low pressure side. As the filter becomes clogged the pressure drop across it and, therefore, across the piston will increase, and the piston is calibrated so that an excessive pressure drop will drive it to the low pressure side.
