Abstract: A wellhead apparatus comprising a first part that is mountable to a portion of a wellhead or proximal to the wellhead and a second part that is mountable to a component of wellhead operation equipment, wherein the component is operatively connectible to the wellhead, wherein the wellhead identifier generates an identifier signal when the first part is proximal the second part and is receivable by a user to identify the wellhead from a plurality of wellheads when the wellhead and the component are operatively connected. A wellhead identifier system comprising a detectable signal generator mountable to a component of wellhead operation equipment, a sensor configured to detect the detectable signal for generating object-based sensory information, and a controller circuit for receiving the object-based sensory information and for identifying a wellhead on a well pad where a wellhead operation has or will commence on the wellhead.

Abstract: An apparatus, a system and a process for regulating a wellhead control mechanism. The apparatus may control actuation of a wellhead control mechanism by moving a moveable body of the apparatus between a first position and a second position. When the apparatus is in the first position a valve actuator is actuatable. When the apparatus is in the second position the valve actuator is physically interfered from actuating. Additionally, when the apparatus is in the second position, the wellhead control mechanism cannot be actuated and is held in either an open, a partially open or a closed position. Further, a system may directly control actuation of a wellhead actuation mechanism.

Abstract: The anesthesia systems have an integrated, extendable clinical center and clinician/anesthesia office that accommodates for a physical separation of clinical and clerical functions. The anesthesia system includes an alarm reversion system which enables a predefined alarm limit to be set and then to be automatically reverted back to an alarm limit existing just before the predefined alarm limit was set.

Abstract: The specification describes anesthesia systems with an integrated, extendable clinical center and clinician/anesthesia office that accommodates for physical separation of clinical and clerical functions. The disclosed anesthesia systems allow for a portion of the system to be brought closer to the patient such that clinical controls can be accessed while tending to the patient airway, without compromising office space available to the clinician or crowding the patient area.

Abstract: An ergonomically designed food slicing machine including a rotatable blade for slicing bulk food product, a motor operably connected to the rotating blade, and a base portion located below the rotatable blade which defines a food slice receiving area. The machine may be provided with a sliced food receptacle operably connected to a scale, a visible indicia correlating to the distance between the gauge plate and rotatable blade, a blade sharpening assembly, a sled for securing the food product and an operator adjusted optimum stroke setting system for automatic operation of the slicing machine.

Abstract: An ergonomically designed food slicing machine including a rotatable blade (800, 2800) for slicing bulk food product, a motor (1400, 3400) operably connected to the rotating blade (800, 2800), and a base (100) portion located below the rotatable blade (800, 2800) which defines a food slice receiving area. The machine may be provided with a sliced food receptable operably connected to a scale (3900), a visible indicia (3502) correlating to the distance between the gauge plate (2500) and rotatable blade (2800), a blade sharpening assembly (900, 2900), a sled (200) for securing the food product and an operator adjusted optimum stroke setting system for automatic operation of the slicing machine.

Abstract: A shutter section includes a stack of circular plates independently rotatable in a nest formed as a laminar formation of rings. The plates have central openings defining a light path. Four central plates in the stack are shutter guide plates with radial guide slots slideably holding shutter blades. Two outer pairs of plates are shutter drive plates connected by cams to the shutter blades. Simultaneous rotation of a shutter guide plate and associated shutter drive plate causes rotation of an associated shutter blade around the light path. Rotation of a shutter drive plate while the associated shutter guide plate is stationary causes the cam to move the associated shutter blade radially. The nest is enclosed by end plates. A motor section has motors driving pinions to rotate the circular plates. The circular plates, rings pinions and shutter blades are made of sheet metal. Shutters may be provided as interleaved pairs each driven by a pair of rotatable drive plates.

Abstract: A protractor comprising a frame and a lever arm coupled thereto. The frame includes a first substantially straight edge and an elongate track adjacent to the first edge. The lever arm includes a second substantially straight edge and a channel which mateably engages the track of the frame. The channel/track combination couples the lever arm to the frame and permits the lever arm to rotate about an axis substantially orthogonal to the first and second edges. The first and second edges intersect at a point allowing a user to describe an angle between the two edges.

Abstract: Associative retrieval of data via the technique of superimposed code words is accomplished by circuitry which automatically generates the codes, and which searches through stored code words to find the ones that match a given query code. Code generation is performed using pseudo-random techniques that are reproducible, obviating the need for a pre-prepared code dictionary. Identification of the codes that meet a match requirement is accomplished by logically AND'ing selected bits from the stored codes, said selection being determined by the query code.

Abstract: The random cell scintillations which have been observed in animated dithered displays are substantially eliminated by establishing a hysteresis band about the dither threshold value assigned to each display cell. The hysteresis band is delimited by upper and lower dither threshold values. Determination of whether the intensity of each picture element of the image to be displayed is to be compared to the upper or the lower threshold value assigned to the corresponding display cell is made based on the current state of the cell.
