Abstract: A method of vulcanizing continuous lengths of elastomeric or plastomeric material which comprises driving the material through an enclosure, within which it is subjected to vulcanizing conditions, in the form of a helix, the helix convolutions in part contacting a drive mechanism and in part being freely suspended. Also an apparatus for vulcanizing continuous lengths of flexible material, comprising an enclosure, means for providing therein an atmosphere at an elevated temperature and pressure, spaced pressure-retaining inlet and outlet means for the continuous flexible material, and drive and support means for feeding the material through the enclosure in the form of a helix comprising partially unsupported convolutions. The invention is particularly useful in the vulcanization of hosing formed for example by extrusion or by helical winding or both.

Abstract: A tire condition sensing circuit includes a ferrite element that changes from a ferromagnetic to a nonferromagnetic state in response to a temperature increase above the material Curie point. The change in state of the element affects the sensor circuit operation such that a normal inductive coupling effect is altered and an abnormal tire condition indicated.

Abstract: An assembly is disclosed for gravity stabilizing a camera and its operator from vehicle attitude changes while aloft and comprises a camera mounting frame assembly; a universal assembly that mounts the camera frame assembly to provide front-to-rear and side-to-side, and rotational motion to the camera mounting frame; an operator mounting assembly to provide front-to-rear and side-to-side motion to the operator; and means interconnecting the camera frame assembly and the operator mounting assembly to effect an integrally combined camera/operator assembly that is stable irrespective of the motions of the airborne vehicle.

Abstract: A method and assembly for making a power transmission belt having driving teeth on opposite surfaces thereof and a tensile member embedded therein. The disclosure also relates to a belt made by the method and apparatus.

Abstract: A rocker provides complex rocking motion by virtue of a volume-compressible foam section sandwiched between two substantially rigid upper and lower plate sections. The upper plate, volume-compressible foam, and lower plate sections are secured to form a single integral unit that provides complex relative motion between the upper and lower sections, which motion exhibits pitch and roll characteristics about a vertical axis through the center of gravity of the rocker when occupied.

Abstract: Apparatus and method for extending the operating range of a condition monitoring system that detects the occurrence of an abnormal condition on a first member moving relative to a second member; the system including a sensor circuit on the first member adapted to be responsive to the condition being monitored and a monitoring circuit on the second member adapted to being affected by the proximate presence of a close-circuited sensor circuit to provide detection signals to circuit means for indicating the condition of the moving member indicative of the open or close-circuited sensor circuit. The system is characterized by a monitoring circuit operating at the threshold of an oscillatory and nonoscillatory state and a close-circuited sensor circuit configuration that affects the monitoring circuit irrespective of its operational state.

Abstract: Magnetically encodable tags in tape format are written sequentially with tire identifying data and applied to the sidewall material of a green tire. The encoded data may be read from the tire at any point in the tire manufacturing process and the signals indicative of the tire identification number converted to an alphanumeric display and/or fed to a process control computer for on-line quality assurance and control or stored as a recorded history of the tire manufacturing process for inventory control.

Abstract: Dual concentric fuel and vapor recovery hoses are disclosed wherein an inner substantially kink-proof reinforced pressure hose carries fuel while an outer larger diameter extruded cover hose provides a vapor recovery path between the two hoses. The dual concentric hoses terminate into an end fitting that provides for separate rotatability of the hoses while also providing direct fuel feed through the fitting and a parallel vapor recovery path.

Abstract: In an electronic detection system, signals indicative of a detected mass of material are related to a selected mass velocity and a detection aperture through which the mass is moved. The pulse output signal from the detector, exhibiting a period related to the mass velocity and aperture length, is conditioned and enhanced as a valid detection signal while all others due to noise, etc. are rejected being outside of a selected threshold for the particular mass velocity and aperture length.

Abstract: An expansion tank is divided into two non-communicating chambers by a flexible elastomeric diaphragm having a peripheral outward projecting, sidewall engaging protrusion that is held in compressed and sealing engagement with the tank walls by a backup ring. The diaphragm-ring assembly facilitates insertion of the diaphragm, provides a positive seal, and prevents the assembly from being forced out of position by extreme pressure differentials.
