Abstract: A process is provided for the chlorination of aliphatic hydrocarbons containing 1 to 4 carbon atoms using hydrogen chloride as the source of chlorine. The process comprises reaction steps operated in tandem in separate zones. First, an unsaturated aliphatic fluorocarbon is oxychlorinated to give the corresponding saturated perchlorofluorocarbon and water, and second, the saturated perchlorofluorocarbon is reacted in the vapor phase with a hydrocarbon to produce the desired chlorinated hydrocarbon, hydrogen chloride and the unsaturated aliphatic fluorocarbon, third, hydrogen chloride and unsaturated aliphatic fluorocarbon are separated from the chlorinated hydrocarbon and recycled to the first step, and fourth, the chlorinated hydrocarbon is further purified by subjecting it to addition chlorination to convert traces of unsaturated aliphatic fluorocarbon to the corresponding saturated perchlorofluorocarbon, which is separated and recycled to the second step.

Abstract: An integral sound absorber and water deflector door panel positionable in space defined between an inner wall and a passenger compartment door panel of an automobile vehicle door assembly. The integral panel is composed of a first polymeric layer made of a water impervious polymeric film having an essentially constant thickness. The first polymeric layer has a first face adapted to contact the interiorly oriented face on the inner wall of the vehicle door assembly and remain in overlying parallel orientation thereto. A second polymeric layer is composed of a polymeric foam integrally connected to the second face of the first polymeric layer in continuous overlying relationship thereto. The second polymeric layer has an outer face opposed to the first polymeric layer which, preferably, has at least one region adapted to directly contact a portion of the exteriorly oriented face of the passenger compartment door panel.

Abstract: A magnetostrictive wire waveguide type position measuring system wherein the wire waveguide is mounted within a small diameter brass tube which, in turn, is mounted by way of resilient suspension components within a rigid outer tube affixed to a position reference frame. The suspension components isolate the waveguide from relatively high frequency shock inputs characteristic of rough environment applications. The position signal is derived from output signal quantities generated by the propagation times of sonic disturbances from a first reference magnet held in a fixed position relative to the outer housing and a second user magnet which moves relative to the outer housing with the element or quantity being monitored.

Abstract: A vacuum cup apparatus having a flexible member with a front side engagable with a workpiece and a back side connectable to a manipulator and communicable with a vacuum source. A passageway is provided between the front side and the back side of the flexible member and is communicable with the vacuum source to provide vacuum to the front side of the flexible member. A recessed pocket formed in the front side of the flexible member provides a lip which defines an opening into the recessed pocket. The lip is engagable with the workpiece for maintaining atmospheric pressure within the recessed pocket when the vacuum cup apparatus is engaged with the workpiece. The establishment of atmospheric pressure within the recessed pocket reduces vacuum provided in the center portion of the front side of the flexible member to reduce or eliminate any tin cupping of the workpiece.

Abstract: A trailer hitch includes a cylindrical receiver perpendicularly mounted on a horizontal laterally extending tube attached to a vehicle. The receiver carries a slider movable between a first, retracted position substantially entirely disposed beneath the vehicle bumper and a second, extended position wherein the slider projects rearwardly of the vehicle bumper and carries a hitch ball for attachment to a towed object. A cam slot and cam follower are cooperatingly formed on the slider and the receiver, with the cam slot having angularly disposed ends for rotation of the slider between first and second angularly disposed position simultaneous with translation of the slider between first and second retracted and extended positions. A decorative cover overlays the exposed portions of the horizontal tube and the slider when the slider is in the retracted position.

Abstract: Traffic management or enforcement is performed through the use of a monitor transponder in the environs of an RF highway toll collection system. When normally operating transponders communicate with a roadside reader system, the roadside system communicates with the monitor transponder, which in turn signals if a valid normal transponder is detected. If no signal is generated by the monitor transponder, it is evident that the vehicle has no transponder or that the transponder is faulty or invalid.

The hollow base member has a bottom and sidewalls, each of the bottom and sidewalls having an outer surface.

Abstract: A tube clip for use with flexible wall dispensing tubes to aid in the dispensing of the tube contents includes a body having a slot in which the closed end of the tube is received so that movement of the body along the tube squeezes the tube to displace the tube contents toward the tube cap. The clip body includes a retainer for retaining that portion of the tube which has been squeezed and emptied, and the retainer permits the emptied tube end to be folded and tucked under the retainer to maintain the tube of a concise configuration and shape as it is used.

Abstract: A sensor detects the absolute angular position of a rotatable clamp arm between full opened and full closed positions. The sensor is coupled to a clamp arm pivot shaft to provide output signals corresponding to the absolute position of the clamp arm. One or more programmable angular position set points are setable at angular positions in advance of the full open and full closed positions of the clamp arm. Outputs are generated when the clamp arm reaches and/or exceeds each set point.

Abstract: The present invention provides a drive assembly for a model toy train which connects a single drive shaft from an electric motor to a pair of discrete truck assemblies. The drive shaft drives a plurality of pinions which in turn drive a pair of worm shafts which extend toward the truck assemblies.

Abstract: A tie-down anchor is secured to a threaded stud projecting from a surface inside an auto to provide a point of attachment for a flexible member such as a cord or loop of a cargo restraint net. The anchor has a tubular stem defining an axial through hole for receiving the stud, and a plurality of barbs extending radially inward into the through hole and angled along the axis of the through hole in the direction in which the stud is inserted. The anchor is pushed directly onto the stud, the barbs deflecting radially outward as the stud is inserted into the through hole. The tips of the barbs engage the threads in a ratcheting manner as the stud is inserted into the through hole. The angled barbs effectively prevent withdrawal from the through hole unless the anchor is rotated to unthread it from the stud. The through hole allows the anchor to be produced as a single, integral piece requiring no further assembly before it is installed in connection with a threaded stud.
