A system for monitoring the flow of water through a pipe. A pipe section is adapted to be located in a water line which includes a metering device having a target displaceable at a rate representative of the rate of flow through the pipe section. A telemetering unit includes a sensor for sensing a target and a receiver for receiving the output of the sensor and transmitting data representative of the flow to a remote receiver. A housing houses the telemetering unit and is releasably secured to the pipe section so that the sensor will sense the metering device target.

An unloader-separator attached to a die casting machine which includes a swing arm having grippers to hold the gate having components thereon. The swing arm holding the gate is rotated to a second position. A punch platen pushes the components through openings in the window platen which corresponds with the components on the gate. The swing arm releases the gate remnants for recycling, rotates to the first position and the cycle repeats. A link arm connects the swing arm to a cam unit which controls the rotation of the swing arm to a cam unit which controls the rotation of the swing arm. The cam unit also provides overload protection.

A quick change mounting system for machine tools provides tool-carrying fixtures having a system-standard dimensional referencing system and fluidically controlled tooling to effect the desired machining operations. The tool-carrying fixtures are mounted to and dismounted from a system-standard tooling plate that carries fluidic supply conduits and mutually operative connectors that effect connection and disconnection of the fluidic system in response to the mounting or dismounting of the tool-carrying fixtures on its mounting plate. A change from one tool-carrying fixture to another can be accomplished by dismounting the former tool-carrying fixture from its mounting plate and mounting a replacement tool-carrying fixture. Since the tool-carrying fixtures have a common tooling plate and the mounting plate defines a system-standard mounting interface in which all dimensional relationships are pre-established, bench fabrication and set-up of each tool-carrying fixture is possible to minimize machine system down time and costs traditionally associated with tooling changeover and set-up.

A rotary indexing mechanism for indexing a shaft or shaft mounted member in precise rotary increments and with precise end-of-movement positioning includes a reciprocable rack and pinion mechanism coupled to a rotatably mounted shaft. The pinion is coupled to the shaft through a one-way clutch so that movement of the rack in a first direction is coupled through the clutch to cause a corresponding rotation of the shaft with the clutch uncoupling the shaft during movement of the rack in the opposite direction. A first stop member(s) is carried by the shaft for movement along a path that orbits the shaft axis. A second stop member is carried by the rack along a linear path that intersects the orbit of the first stop member. As the rack rotates the shaft through a rotary increment, the rack-carried second member is positioned in the orbit of the first stop member with the two members engaging to halt further rotary movement. The rotary indexing mechanism allows successive rotary increments with precise end-of-movement positioning determined by the two interengaging members. In the preferred embodiment, one or both of the members is adjustable to provide various end-of-movement positions.

Rotary indexing mechanism

A modularly expandable integrated process machine system incorporating a rotary indexing mechanism therefor. The machine system is made up of a support platform with predefined work station positions which each have the same dimension tool mounting configuration. Pallets are advanced between workstations by an endless chain incremented by a precision rotary indexing mechanism capable of precise end-of-movement positioning and variable force advancing.

A thread cutting work station includes a carriage assembly mounted on guideways for guided movement under the control of a linear actuator between an initial, home position and a forward position for cutting threads in or upon a workpiece. A collet is connected to a drive motor and carries a tap for thread cutting. In operation, the linear actuator accelerates the carriage assembly from the initial, home position along the guideways towards the workpiece with the rotating tap entering the to-be-threaded bore to initiate the thread cutting operation with the subsequent feed rate controlled by the rotating tap. After completion of the thread cutting step, the drive motor is reversed to withdraw the tap from the threaded bore, and the linear actuator is controlled to rapidly move the carriage assembly to its initial position. The use of a separate linear actuator to advance and retract the carriage assembly allows for the rapid advance and retraction of the tap to and from the to-be-threaded bore to increase overall efficiency.

Thread tapping machine tool

A machine component installer for installing bearings, pins, bushings, and the like into a machine casting or similar component includes a reloadable carousel for accepting plural component stacks, a pivotally mounted claw-arm for grasping a bearing presented by the carousel and for swinging the grasped bearing into a pre-installation position, and a press for determining that all components are properly positioned and for pressing the bearing into a bore. The carousel includes a rotatably mounted turntable with guides for accepting plural stacks of bearings. The bearings drop, on a one-by-one basis, through an opening in the turntable plate to a presentation position. The claw-arm includes opposed spring biased fingers for grasping each bearing presented by the carousel and for swinging the bearing into position above a ram. The claw-arm is designed to self-tighten about the grasped bearing as the arm is rotated to present the bearing to the ram. A qualifying device determines if the machine casting is in proper position and, if so, allows the ram to press the bearing into place.

Machine component installation device

An adaptable machining system includes a plurality of transport units mounted on a machine base with each transport unit carrying a system-standard mounting plate that receives a tool-carrying module. Each tool-carrying module includes a machining tool and associated motor mounted on a system-standard tooling plate which, with the mounting plate of the transport unit, define a system-standard tooling interface. The transport units, under the coordinated control of a system controller, advance their respective tooling modules to and from a work piece to accomplish their machining function. The mounting plate of each transport unit establishes an orthogonal reference system relative to the operating axes of the machine so that the position of each tool carried on a tooling module is known relative to the operating axes of the machine. Tooling change over from one set of tooling modules to another can be accomplished with a minimum of machine down time by removing the prior set of tooling modules and installing a replacement set. Since the system-standard tooling interface pre-establishes an orthogonal reference system for each tooling module, each tooling module can be bench fabricated and set-up to minimize tooling set-up time.

Adaptable machining system

A support for sensing the proper positioning of a workpiece and holding the workpiece for a machining operation in response to the proper positioning includes elements for sensing the position of the workpiece at a plurality of locations on the workpiece and a power drive mechanism for operating a clamp to secure the workpiece in the proper position. The sensing elements are connected in series to a power source and are actuated by engagement with predetermined locations on the workpiece when the workpiece is in the proper position. The clamp includes clamp arms which swing laterally away from seats for the workpiece as the clamp arms are moved forward to release one workpiece and accept another.
