Pivotal movement of the handle is limited in such manner that the handle cannot be further pivoted, even in small increments, after sufficient tension has been sensed by the handle.

Abstract: A container closure includes a body for mounting on the container. The body defines a dispensing orifice. A flow control device, such as a lid, is disposed on the body for being moved between positions opening and closing the dispensing orifice. A tamper-indicating member is provided as a unitary extension from the lid. A first frangible web connects the member to the lid. An anchor is connected with a second frangible web to another portion of the tamper-indicating member, and the anchor is retained by the closure body. The tamper-indicating member also includes a graspable pull tab. The tab can be pulled to completely sever the frangible webs connecting the tamper-indicating member to the lid and to the anchor. This permits the lid to be opened while providing evidence of tampering with the closure.

Abstract: A wide angle passive infrared energy sensor includes an infrared transducer. Energy in the field of view which is essentially normal to the transducer impinges directly on the transducer which can in turn generate an electrical signal in response thereto. Radiant energy at the peripheral regions of the field of view, on the order of 90.degree. with respect to a center line normal to the detector, is parabolically reflected onto the detector.

Abstract: The invention relates to a process for drying timber in which the timber is fed gradually through a drying tunnel while at the same time being permeated by a drying air with a temperature below 80.degree. C. transported primarily in the longitudinal direction of the tunnel. Said drying tunnel is divided into two separate sections with said drying air divided into two circulating substreams, of which one flows through the first section of the tunnel in the direction of motion of the timber and the other through the second section of the tunnel contrary to the direction of motion of the timber, after which said substreams are conditioned and returned to their section.

Abstract: A control system including interfaced hand and foot control assemblies for independently conditioning an off-highway implement by selectively positioning a regulator thereof relative a neutral position. The hand and foot control assemblies utilize a common force transfer mechanism in the form of a push/pull cable for moving and positioning the regulator. The foot control assembly includes a self-centered foot pedal and linkages for arranging the push/pull cable relative to the regulator in a manner inhibiting binding forces from being imparted to the cable. The hand control assembly requires independent movement of a control lever in two different planes to shift the hand control assembly from a neutral condition. Moreover, the hand control assembly is isolated from spring forces acting to self center the foot pedal and thus requires low operator efforts to adjust the position of the regulator. The control system of the present invention further includes a mechanism for governing operation of the regulator.

Abstract: A hydraulic system for a wheel loader having an implement arranged for elevational and tilting movements relative to a frame of the loader. The hydraulic system includes selectively operable lifting and tilting circuitry for adjusting the position of the implement and a shock absorbing mechanism arranged in combination with the lift circuitry for allowing relative movement between the implement and the frame to provide a cushioning effect which reduces pitching of the loader. To inhibit inadvertent vertical displacement of the implement, the shock absorbing mechanism is responsive to an initial lifting action of the implement. In a preferred form of the invention, the shock absorbing mechanism is responsive to hydraulic conditions indicative of imminent tilting movement of the implement thereby eliminating inadvertent vertical displacement of the implement when the implement reaches a limit of its tilting travel.

Abstract: A method for regenerating exhausted anion and cation exchange resins for service in an associated mixed bed demineralizer. The method utilizes a portion of the exhausted anion and cation resins to form buffer zones which reduce cross-contamination between the anion and cation resins during regeneration. Alternatively, a relatively inert material having a specific density intermediate to that of the anion and cation resins can be used to form the buffer zones. The materials which form the buffer zones remain in the regeneration system and are not returned to the service vessels with the regenerated resin. The method includes an improved technique for terminating the transfer of cation resin from a separation vessel.

Abstract: For machine used to balance disk brake rotors having radial walls defining tapered recesses by inserting tapered weights into selected recesses, a magazine holds a stack comprised of a controlled number of the weights and permits the weights to exit individually. Each exiting weight is oriented radially with its narrow end pointing into a selected recess. An inserter and a double-acting, pneumatic, piston-cylinder apparatus are provided for removing the lowermost weight from the magazine and inserting such weight into the selected recess. Photoelectric detectors are provided for detecting when the magazine has been depleted of a specified number of the weights, when the magazine holds the controlled number of the weights, and when the magazine has been completely depleted of the weights. The magazine has a gate for admitting the weights under certain conditions.

Abstract: A lubrication system for a cotton harvester having a plurality of harvesting units. The lubrication system comprises a lubricant source for providing pressurized lubricant to each of the harvesting units to facilitate their operation and a control mechanism for measuring cyclic operations of harvesting units operating components during a harvesting procedure. The control mechanism controls operation of the lubricant source such that the amounts of lubricant provided to the harvesting units during a lubrication cycle is correlated to the lubricant usage of the harvesting units during the harvesting procedure. A salient feature of the present invention relates to a display for visually indicating the cyclic operations remaining for the harvesting units before another lubrication cycle is due to be commenced. The display furthermore provides a visual indication relating to the operating performance of the lubrication system.
