Abstract: Example implementations relate to printer valve seals. In some examples, a printer valve to receive print substance from a fluid conduit and transmit the received print substance to a print cartridge can include a valve neck having a first seal member to provide a seal between the valve neck and an inlet of the print cartridge, and an actuator having a second seal member to form a seal within a valve body of the printer valve while the valve neck is detached from the inlet of the print cartridge.

Abstract: An ink tank includes a cap assembly attached to the ink tank by a preloaded hinge that defines a rotational axis of the cap assembly when the cap assembly is opened and closed. The preloaded hinge biases the cap assembly to an opened position when the cap assembly is unlatched. The cap assembly includes a cap housing, a bung retained within the cap housing, a spring disposed between the cap housing and the bung, a latch to hold the cap assembly in a closed position, where in the closed position the spring applies a force to provide a seal between the bung and the ink tank. The cap assembly also includes an effector that is operative when the cap assembly is unlatched, to sequence a closing of an internal valve of the ink tank and a breaking of the seal between the bung and the ink tank thereafter.

Abstract: An example ink tank includes an ink tank and a cap assembly attached to the ink tank with a preloaded hinge. The hinge rotates the cap assembly from a closed position to an open position when the cap assembly is unlatched. The cap assembly includes a bung to seal the ink tank during a partial rotation of the cap assembly when the cap assembly is unlatched. The ink tank also includes spring-loaded linkage connected to a valve in the ink tank. An effector extending from the cap assembly engages the spring-loaded linkage when the cap assembly is latched and disengages from the spring-loaded linkage after the cap assembly is unlatched. The spring-loaded linkage opens the valve when engaged with the effector, and closes the valve when disengaged from the effector, while the bung maintains a tank seal until the internal valve is closed.

Each of the plurality of SSADCs is coupled to an output of a different one of the unit cells. Each each of the plurality of SSADCs includes: a comparator having a positive input and a negative input and a comparator output, the comparator being contained in a first layer; and a counter coupled to the comparator output and contained in a second layer. The counter is electrically coupled to the comparator with a through a silicon via.

Abstract: An integration capacitor network for connection to a photo-current source includes: an input; a first path connected between the input and a reset voltage, the first path including a first integration capacitor and a first cascode transistor, the first cascode transistor coupled between the input and the first integration capacitor; and a second path connected between the input and the reset voltage, the second path including a second integration capacitor and a second cascode transistor, the second cascode transistor coupled between the input and the second integration capacitor. Gates of the first and second cascode transistors are connected to a reference voltage and charge is accumulated on the first integration capacitor until a voltage on the first integration capacitor exceeds the reference voltage and then charge is accumulated on the second integration capacitor.

Abstract: A selectable drive printing device includes a feedshaft to selectively drive a print drive system and a scan drive system, and a shifter to selectively shift a drive selector assembly of the selectable drive printing device between a scanning system drive position wherein the scan drive system is driven and a printing system drive position wherein the print drive system is driven. The shifter is coaxially and rotatably coupled around the feedshaft. Further, the shifter selectively drives the print drive system and the scan drive system based on an angular position of the shifter about the feedshaft.

Abstract: This invention relates to a method and system for increasing the utilization of the supply of acetylene from two acetylene sources. The flow is provided at a substantially constant delivery pressure to a point of use, such as a customer point of use. A portable apparatus is configured to operably connect to each of the two acetylene sources simultaneously and during operation automatically provide flow from one of the acetylene sources through various valving and piping assembled onto the portable apparatus followed by supply to a customer point of use.

Abstract: An ontology-based search engine enabling search criteria to be defined within a Virtual Earth visualization system. The search criteria can be entered directly as a set of ontology-based keywords or “search terms” and together with a number of optional spatio-temporal search criteria that are combined to become a spatial database query which is subsequently submitted to a spatial database whereby the search results are returned to the search client, for display directly into the Virtual Earth visualization system.

Abstract: A system for assisting in the diagnosis of errors in manufacturing machinery is disclosed wherein sensors are associated with the machinery at monitoring zones for detecting errors and generating sensor signals representing the errors. Video cameras are located at monitoring zones associated with specific sensors. A computer readable medium is in communication with the cameras for receiving video of the process. A set of computer readable instructions are embodied within the computer readable medium for receiving input selecting machine sensors and cameras, triggering, and producing the pre-event and post-event videos for the trigger signals. Operating instructions are for continuously storing video output in temporary memory, receiving sensor signals, and processing the sensor signals to determine if a trigger signal is required. After a trigger signal, video is copied from temporary memory into permanent memory to provide the pre-event video, and post-event video is recorded and stored in permanent memory.

Abstract: A landscaping fabric that includes a pesticide is made by extruding molten polypropylene from a plurality of holes to generate filaments. The filaments are cooled and drawn to cause the filaments to become reduced in diameter. The filaments are distributed onto a belt to form a mat and the mat is compressed to bond the filaments into a nonwoven fabric. An insecticide is applied to the nonwoven fabric and the nonwoven fabric and insecticide combination is dried.

Abstract: The present invention is an improvement to the method and apparatus for measuring volatile compounds in an aqueous solution. The apparatus is a chamber with sides and two ends, where the first end is closed. The chamber contains a solution volume of the aqueous solution and a gas that is trapped within the first end of the chamber above the solution volume. The gas defines a head space within the chamber above the solution volume. The chamber may also be a cup with the second end. open and facing down and submerged in the aqueous solution so that the gas defines the head space within the cup above the solution volume. The cup can also be entirely submerged in the aqueous solution. The second end of the. chamber may be closed such that the chamber can be used while resting on a flat surface such as a bench. The improvement is a sparger for mixing the gas with the solution volume. The sparger can be a rotating element such as a propeller on a shaft or a cavitating impeller.

Abstract: A chemical barrier is formed by injecting a suspension of solid particles or colloids into the subsurface. First, a stable colloid suspension is made including a surfactant and a non-Newtonian fluid. This stable colloid suspension is characterized by colloid concentration, colloid size, colloid material, solution ionic strength, and chemical composition. A second step involves injecting the optimized stable colloid suspension at a sufficiently high flow rate to move the colloids through the subsurface sediment, but not at such a high rate so as to induce resuspending indigenous soil particles in the aquifer. While injecting the stable colloid suspension, a withdrawal well may be used to draw the injected colloids in a direction perpendicular to the flow path of a contaminant plume. The withdrawal well, may then be used as an injection well, and a third well, in line with the first two wells, may then be used as a withdrawal well, thereby increasing the length of the colloid barrier.
