Abstract: An insert assembly for fluid management includes an engagement mechanism and a fluid distribution mechanism with a plurality of fluid connectors configured to transmit fluid therethrough, and a sleeve defining an opening. The fluid distribution mechanism is rotatably coupled to the engagement mechanism such that the two are rotatable relative to each other around a longitudinal axis of the engagement mechanism. An elongated tube extends through the sleeve and at least one valve is coupled to the plurality of fluid connectors by a corresponding fluid line. At a distal end of elongated tube, the elongated tube and valve are coupled via an attachment mechanism, which includes at least one receiving region for releasably receiving the valve. The attachment mechanism, elongated tube and valve form a distal assembly, which distal assembly is configured to be inserted into a port and rest at or near a bottom surface of a covered container.

Abstract: An optical chemical level-sensing device includes an elongated tube for insertion into a top opening of a storage container, with a portion extending above the top of the storage container, which couples to a sealed control unit. A float device resides in the elongated tube in the storage container containing a liquid chemical solution, which includes a target surface configured to reflect optical signals. The sealed control unit includes an optical time-of-flight sensor and a lens that serves as a physical barrier between the liquid chemical solution and the optical time-of-flight sensor, while also allowing optical signals to pass through. The optical time-of-flight sensor emits optical signals through the lens toward the target surface of the float device and measures a return time of reflections of the optical signals off of the target surface to determine a level of the liquid chemical solution within the storage container.

Abstract: Aspects of the disclosure relate to cash handling devices that provide intelligent monitoring and management of cash cycles. A cash handling device having at least one processor, a communication interface, and memory may receive, from a mobile device, a request to process a pre-staged transaction. Subsequently, the cash handling device may generate and present a graphical identifier based on the mobile device requesting access to the cash handling device. Next, the cash handling device may verify that the mobile device is authorized to perform the pre-staged transaction based on the graphical identifier being scanned by the mobile device and cause a connection to be established between the cash handling device and the mobile device. Thereafter, the cash handling device may identify and process the pre-staged transaction associated with the mobile device. Then, the cash handling device may generate a notification indicating completed processing of the identified pre-staged transaction.

Abstract: Provided is an increased capacity firearm ammunition magazine with a metallic body. The body is dimensioned to compatibly replace a (OEM) polymer or polymer over metal single stack magazine. The body has walls with exterior dimensions compatibly matching those of the OEM magazine and that are thinner than those of the OEM magazine. The thinner walls allow an at least partially laterally offset arrangement of cartridges therein. A longitudinal exterior ridge extends along a forward wall of the body and is configured from the metallic body walls and sized to compensate for forward-to-aft dimensioning difference compared to that of the OEM magazine.

Abstract: A kickover tool for retrieving a used gas lift valve installed within a gas lift mandrel connected along a wellbore tubular string and installing a new gas lift valve within the gas lift mandrel. The kickover tool may include a housing, a first holder configured to hold the used gas lift valve, a first displacement mechanism operable to move the first holder between a retracted first holder position in which the first holder is adjacent the housing and an extended first holder position in which the first holder is spaced away from the housing, a second holder configured to hold the new gas lift valve, and a second displacement mechanism operable to move the second holder between a retracted second holder position in which the second holder is adjacent the housing and an extended second holder position in which the second holder is spaced away from the housing.

Abstract: A method of operating a sequencing batch reactor process includes introducing wastewater to be treated into the sequencing batch reactor and subjecting the wastewater to treatment in the sequencing batch reactor in an aerated anoxic mode in in which a quantity of oxygen is supplied at a level insufficient to meet a biological oxygen demand of the wastewater, but sufficient to cause simultaneous nitrification and denitrification reactions to occur in the wastewater.

Abstract: A housing can have a first attachment point for an actuator wherein the actuator can be attached to the housing and a pin lift plow. The wearable mechanical robotic device can have a rolling pin lock. A cam wherein the cam can rotate around an axis and can come into contact with a cam follower and the rolling pin lock. A plunger wherein the plunger can be attached to the cam follower wherein the plunger compresses a spring against a base. An outer frame having at least one guide for the rolling pin lock. The housing can have at least one second attachment point wherein at least one frame is attached to the housing by at least one fastener.

Abstract: Training accessories and methods for improving athletic techniques, such as, for example, tackling form for football. A display can be coupled to a piece of athletic equipment, such as a tackling dummy, and the display depicts a symbol at a time at which a player is or is about to interact with the equipment or perform a movement or action. An input is provided of the player's identification of the depicted symbol and compared to the symbol that was actually depicted. The player's correct identification of the depicted symbol can indicate that the player performed the movement or action, or the interaction with the equipment, with appropriate form. A player's failure to correctly identify the depicted symbol can indicate to a coach that the player may need further instruction on proper technique or form with which the movement or action, or the interaction with the equipment, should be performed.

Abstract: A downhole tool for connecting with a conveyance line. The downhole tool may be or comprise a connector assembly operable to connect to the line. The connector assembly may include a first connector, a second connector, a latching member, and a rotatable member. The first connector and the second connector may be configured to accommodate the line therebetween. The latching member may be latched against the first connector. The rotatable member may be operatively connected with the latching member such that rotation of the rotatable member with respect to the latching member causes relative axial movement between the latching member and the rotatable member thereby forcing the first connector and the second connector toward each other to compress the line therebetween to therefore connect the connector assembly to the line.

Abstract: A wheel assembly configured to detachably connect to a downhole tool to thereby reduce friction between the downhole tool and a sidewall of a wellbore through which the downhole tool is conveyed.
