Abstract: A nozzle for delivering vaporized liquid material has a cylindrical housing with a central, cylindrical cavity having a fluid inlet and a fluid outlet. The nozzle also has a plunger inserted into the fluid outlet of the housing so that the plunger and the housing form a fluid path. The plunger is moveable between a first position and a second position. A plunger stop is attached to the housing at the fluid inlet. A spring retainer is attached to the plunger. At least one spring is disposed between the housing and spring retainer to urge the plunger towards the first position. A method includes the steps of biasing a plunger moveable relative to a housing, with a fluid passage defined by the housing and the plunger, towards a first position; and providing fluid pressure to the fluid passage to urge the plunger away from the first position.

Abstract: An apparatus for recovering a desired fraction of a raw material bearing the desired fraction has a vessel or cell defining a treatment chamber therein, with an inlet into the chamber for introducing a slurry of raw material to be treated into the chamber. An attrition zone is defined in a portion of the chamber proximate the inlet in the flow path of material introduced into the chamber, the particles being caused to impact against each other in the attrition zone to cause attritioning thereof. A floatation zone is defined in a distal portion of the chamber, in flow communication with the attrition zone, in which attritioned particles from the attrition zone can be contacted with gas bubbles to form a froth phase separated from the slurry by a slurry-froth interface such that the desired fraction is either selectively taken up into the froth phase by the gas bubbles or selectively left behind in the slurry. An outlet from the chamber for the froth phase is present.

Abstract: A piston pig for pushing pigs from a larger diameter conduit into a smaller diameter conduit, where one embodiment includes a cylindrical body with a first sealing disc attached to the body and adapted to seal against the larger diameter conduit and maintain a pressure differential across the body of the piston pig. The piston pig also includes a second sealing disc attached to the body and capable of sealing against the smaller diameter conduit and maintain a pressure differential across the body. Certain embodiments also include a pressure control device, such as a resilient flapper disc, to limit the differential pressure across the body. Some piston pig embodiments may also include an end cap attached to, and slidable relative to, the body, where the end cap has a closed position in which fluid cannot bypass the end cap and an open position in which fluid can bypass the end cap.

Abstract: A signal multiplexer for N channel signals of different frequency bands that utilizes only N+1 hybrid couplers and presents a constant impedance to the transmitters that supply the N channel signals. The channel signals are coupled by separate ones of N of the N+1 hybrid couplers to N pairs of matched band pass filters. The outputs of the filters are combined in a signal combiner to form a pair of quadrature phase multiplexed channel signals that are converted to a single multiplexed output signal by the remaining hybrid coupler.

Abstract: A signal separator and bandpass filter that use plates with posts. The signal separator uses two bandpass filters to separate two signals of different carrier frequencies from one another. The bandpass filters each have a transmission line with the metallic plates disposed along its length. The number of plates and the distances between adjacent plates determine the bandwidth and the rejection capability of the filter.

Abstract: An apparatus for latching a door against a frame has a door pin extending from the door and a handle lever rotatably mounted to the door and having an extending handle pin. A latch bar is mounted for reciprocating travel relative to the frame, the latch bar having a first slot having a cam surface adapted to receive the door pin, and a second slot adapted to receive the handle pin. The latch bar and handle have a first position where the handle pin enters the second slot and the door pin enters the first slot, and a second position where the handle pin contacts the second slot and the cam surface bears against the door pin. Rotation of the handle when the latch bar is in the first position causes the handle pin to bear against the second slot, moving the latch bar in a latching direction from the first position to the second position, so that the first slot on the cam surface bears against the door pin and urges the door in a closing direction.
