Abstract: The specification discloses a controller housing that utilizes card guides that may be installed and removed without the use of tools. Various arrangements of the controller housing with and without the card guides allows for the controller housing to accept electronic circuit cards of varying sizes. Thus, if a manufacturer desires to increase the number of points on an input/output card, for example, those additional points need not necessarily be contained in a card having the same form factor. Instead, the manufacturer may provide a larger form factor card and that card may be inserted into the controller housing by appropriately adjusting the location of the card guide within the particular opening into which the new card is to be inserted.

Abstract: A programmable coolant nozzle system includes a coolant fluid nozzle fixed to a manifold so that the centerline of the nozzle and the centerline of the manifold block are perpendicular.

The invention includes a method which allows coolant fluid to be rotatably directed from a nozzle assembly and to be commensurate with any change in position of the working tool of a machine tool center.

Abstract: An apparatus for shutting off power to a gate motor is disclosed when the gate to which the gate motor is connected is opened or closed manually. In a preferred embodiment a sensor is activated that immediately shuts off power to the gate motor upon insertion of a crank into a receptacle on a pulley of the power driven gate movement system to commence manual opening or closing of the gate with the crank. Rotation of the crank in the appropriate direction either opens or closes the gate. Power is restored to the gate motor when the sensor determines that the crank has been withdrawn from the pulley.

Abstract: Embodiments of the present invention are directed to a fluid dispenser for dispensing landscape maintenance fluids or the like which contain products such as fertilizers, herbicides, and pesticides. The fluid dispenser injects the fluids directly into the mainstream of an irrigation system. The dispensing system operates by shunting a portion of the main irrigation water stream through a bypass to the dispenser containing the product to be dispensed. The water dilutes the product to be applied, and is injected back into the main irrigation stream by the back pressure of the irrigation system. When the irrigation is completed, the fluid flow in the main irrigation stream is reduced or terminated and the pressure drops. After the pressure drops, the fluid ceases to be diverted to the container, and the main irrigation stream drains.

Abstract: A method of scrubbing SOx, NOx compounds and other air toxins from a flue gas stream. In the method, two distinct unit operations are amalgamated to scrub SOx, NOx and other air toxins compounds from a flue gas stream. More specifically, there is a dry scrubbing operation and a wet scrubbing operation. The dry injection scrubbing operation involves contacting a flue gas stream containing SOx and NOx compounds with a sorbent for removing substantially all of the SOx and NOx compounds present in the stream. The second wet scrubbing operation involves contacting the stream to remove any residual SOx, NOx compounds, and other air toxins remaining in the stream.
