A joystick controller comprises an operating shaft mounted for pivotal movement relative to a housing. The joystick controller is configured such that when the operating shaft is in a null position a release of pressure applied on the operating shaft is effective to lock the joystick so as to prevent further pivotal movement. Re-application of pressure on the operating shaft is effective to unlock the joystick.

A system for providing the ability to obtain consumption data from a communication device used to transmit accumulated data from the meter register. The system includes a programming port formed as part of the communication device. The programming port includes the programming coil that allows the accumulation data received from the meter register to be read by an interrogation device. Further, the programming coil allows programming information to be transferred to the communication device from the interrogation device. The system can also include a reading module coupled to the programming port of the communication device through an inductive coupling. The reading module can extend through a pit lid such that the reading module can be accessed without removing the pit lid.

A spring-biased filter assembly for a liquid dispenser is disclosed that permits ready removal of a filter assembly from a filter housing. The filter housing includes a liquid inlet, a liquid outlet, and a liquid passageway therebetween. The filter housing also has an opening in communication with the liquid passageway. The filter assembly comprises a closure element positioned in the opening and releasably coupled to the filter housing through movement between connected and disconnected positions with respect to the filter housing. A filter element is positioned in the liquid passageway and coupled to the closure element. A biasing member is coupled to the closure element and the filter element and biases the closure element into the connected position.

A method or device is provided for connecting a centrifugal blower to a process requiring the flow of forced air such that the flow of air may be reversed. The method is applied to a process that benefits from the switching of the direction of air flow to either positive pressure or suction. The method was developed primarily use in the forced aeration composting process but may have other applications. The invention consists of a damper with a plurality of vanes rotating on parallel shafts, which is closely coupled to both the inlet and outlet of a centrifugal blower. When set to provide positive pressure, the vanes direct outside air to the blower intake and direct the blower discharge to the process requiring aeration. When set to provide suction, the vanes direct air from the process to the blower intake and direct the blower discharge to a port that may be connected to an air pollution control device. The shafts are connected by co-planar crank arms and linkages, such that the damper setting may be switched by a single actuator, thereby simplifying the automation of the reversal of air flow.

A manifold for a liquid material dispenser has a unitary manifold body with process air and liquid material passages formed therethrough. Heaters for heating the process air and liquid material are both coupled directly to the manifold body and cooperate to simultaneously heat both the air and liquid material. The air and liquid material heaters may be arranged in either a generally vertical orientation, or a horizontal orientation with respect to the manifold body. In one embodiment, the process air heater includes a cylindrical member which is substantially exposed to the process air to optimize heat transfer from the cylindrical member to the process air.

A manifold for distributing liquid and process air to at least one dispensing module including a manifold body adapted to overlie at least a portion of a substrate. The manifold body includes a front surface having a liquid outlet vertically spaced above a process air outlet. The front surface of the manifold body is configured to carry at least one dispensing module having a liquid inlet and a process air inlet in communication with the liquid outlet and process air outlet in the manifold body. A groove is formed in the front surface of the manifold body between the liquid outlet and process air outlet and adapted to collect any liquid dripping from the liquid outlet toward the process air outlet when the dispensing module is removed from the manifold body thereby preventing the liquid from reaching the process air outlet.

The multi-stage interconnection network of the present invention includes the use of switches in the first stage that have parallel path seeking capabilities. With these switches, a directed flash-flood can be instigated from any one node wherein multiple paths through the network to a designated destination node are tried in parallel in an attempt to find a connection path therebetween. The switches in the first and second stages are interconnected such that each switch in the first stage is connected with every possible priority level to the switches of the second stage. The parallel path seeking switches and network are further configured to test for rejection of the flash-flood by monitoring all connections in combination.
