Abstract: A valve position indicator for a valve includes a spline barrel, indicator flag, and follower. The spline barrel may be generally tubular and may be positionable about a tail stem protector of the valve. The spline barrel may have a helical slot formed therein. The spline barrel may be rotatably coupled to the tail stem protector of a valve. The indicator flag may be coupled to the spline barrel and may extend radially therefrom. The follower may be coupleable to a tail stem of the valve. The follower may extend in a direction perpendicular to the extent of the tail stem. The follower may extend through a slot in the tail stem protector and the helical slot of the spline barrel when the spline barrel is positioned about the tail stem protector.

Abstract: A device for buttering an ear of corn having a butter stick platform and a corn rest. The butter stick platform has an upper butter base surface for supporting a butter stick, and a peripheral wall extending downward to a base. A containment wall can surround and be separated laterally from the peripheral wall to provide a trough between the peripheral wall and the containment wall. The corn rest has a corn base having a concave upper surface with openings for placement thereupon of an ear of corn, and a frame having side walls that extend downwardly partly into the trough when the corn rest is in a first position resting upon a stick of butter. As the butter stick melts and is used, the frame rides downward into the trough to maintain contact between the ear of corn and the butter stick.

Abstract: A chopper stabilized amplifier that utilizes a multi-frequency chopping signal to reduce chopping artifacts. By utilizing a multi-frequency chopping signal, the amplifier DC offset and flicker noise are translated to the higher chopping frequencies but are also smeared, or spread out in frequency and consequently lowered in amplitude. This lower amplitude signal allows for less stringent filtering requirements.

Abstract: A pharmaceutical waste disposal assembly (10) for disposing of fluid pharmaceutical waste comprises a fluid receiver body (219) and a fluid absorber (270A). The fluid receiver body (219) receives the fluid pharmaceutical waste. The fluid absorber (270A) is positioned within the fluid receiver body (219). The fluid absorber (270A) absorbs and retains the fluid pharmaceutical waste. The fluid absorber (270A) includes a plurality of levels (270L, 270M, 270U) that are spaced apart from one another. The plurality of levels (270L, 270M, 270U) can be oriented substantially vertically relative to one another so that the fluid pharmaceutical waste is distributed to each of the plurality of levels (270L, 270M, 270U) of the fluid absorber (270A).

Abstract: A pharmaceutical waste disposal assembly (10) for disposing of raw pharmaceutical waste comprises a first receiver body (19) and a first reaction agent (287). The first receiver body (19) receives the pharmaceutical waste. The first receiver body (19) includes a receiver bottom (283). The first reaction agent (287) is positioned within the first receiver body (19) and spaced apart from the receiver bottom (283). The pharmaceutical waste reacts with the first reaction agent (287) to change the pharmaceutical waste in one of a chemical and physical manner so that the pharmaceutical waste is unrecoverable. The first receiver body (19) can receive fluid pharmaceutical waste and/or solid pharmaceutical waste. The first reaction agent (287) may include one or more of a denaturant, an emetic and a tittering agent. For example, the first reaction agent (287) may include one or more of quinine, ipecac and denatonium benzoate.

Abstract: A pharmaceutical waste disposal assembly (10) comprises a waste receiver (212) that receives pharmaceutical waste, the waste receiver (212) including a radio frequency identification tag (200) that is configured to transmit a radio frequency signal that identifies the waste receiver (212). The pharmaceutical waste disposal assembly (10) can further comprise a receiver retainer (1516) that selectively receives the waste receiver (212). The radio frequency identification tag (200) is configured to transmit the radio frequency signal that is usable to track a location of the waste receiver (212) regardless of whether or not the waste receiver (212) is positioned within the receiver retainer (1516). The receiver retainer (1516) can include an identification reader (1500) that reads the radio frequency signal and is configured to store information from the radio frequency signal that inhibits use of the waste receiver (212) following removal from and repositioning into the receiver retainer (1516).

Abstract: A pharmaceutical waste disposal assembly (10) for disposing of one or more of fluid pharmaceutical waste and solid pharmaceutical waste includes a first waste receiver (614) and a receiver retainer (16). The first waste receiver (614) includes a first receiver body (621) having a first body access (621BA). Additionally, the pharmaceutical waste moves in a first direction (695C) toward the first body access (621BA) through which the pharmaceutical waste is directly received by the first receiver body (621). The receiver retainer (16) substantially encloses the first waste receiver (614). Further, the first waste receiver (614) is removable from the receiver retainer (16). Moreover, one of the first waste receiver (614) and the receiver retainer (16) includes a first waste guide (667A) that guides the pharmaceutical waste in a second direction (695A) away from the first body access (621BA) and in the first direction (695C) toward the first body access (621BA).

Abstract: A pharmaceutical waste disposal assembly (10) includes a receiver body (19), a receiver guide (62), a fluid absorber (70) and a fluid distributor (64). The receiver body (19) receives fluid pharmaceutical waste. The receiver guide (62) guides the fluid pharmaceutical waste into the receiver body (19). The fluid absorber (70) is positioned within the receiver body (19), and is adapted to absorb at least a portion of the fluid pharmaceutical waste that is received by the receiver body (19). The fluid distributor (64) is coupled to the receiver guide (62), and extends at least partially into the fluid absorber (70) so that the fluid distributor (64) distributes the fluid pharmaceutical waste within the fluid absorber (70). The fluid distributor (64) includes a plurality of distributor apertures (278) that allow the fluid pharmaceutical waste to flow from the receiver guide (62) to the fluid absorber (70).

Abstract: A cancellation feature (2203) for a pharmaceutical waste disposal assembly (10) having a first surface (2201) and a second surface (2202) can include a first cancellation member (2204) that is secured to the first surface (2204) and a second cancellation member (2205) that is secured to the second surface (2205). The second cancellation member (2205) automatically moves from a pre-engaged configuration that allows engagement with the first cancellation member (2204) to a post-engaged configuration that inhibits engagement with the first cancellation member (2204). The automatic movement occurs after engagement and/or during disengagement between the second cancellation member (2205) and the first cancellation member (2204). The first surface (2201) can form a portion of a receiver that receives pharmaceutical waste, and the second surface (2202) can form a portion of a receiver retainer that retains the receiver.
