Abstract: Secondary batteries and methods of manufacture thereof are provided. A secondary battery can comprise an offset between electrode and counter-electrode layers in a unit cell. Secondary batteries can be prepared by removing a population of negative electrode subunits from a negative electrode sheet, the negative electrode sheet comprising a negative electrode sheet edge margin and at least one negative electrode sheet weakened region that is internal to the negative electrode sheet edge margin, removing a population of separator layer subunits from a separator sheet, and removing a population of positive electrode subunits from a positive electrode sheet, the positive electrode sheet comprising a positive electrode edge margin and at least one positive electrode sheet weakened region that is internal to the positive electrode sheet edge margin, and stacking members of the negative electrode subunit population, the separator layer subunit population and the positive electrode subunit population.

Abstract: An articulated work machine with individually powered drive members. Each drive member is controlled by a corresponding electric motor, and is capable of rotating at a different speed and in the opposite rotational direction than all other drive members. Each drive member may also remain stationary while all other drive members rotate. The electric motors are commanded by a controller, which may be directed by inputs from by an operator. A lift arm extends from the front end of the vehicle, and a platform station extends from the rear end of the vehicle. The lift arm is connected to a tool, such as a bucket.

Abstract: A beadlock to secure a tire to a wheel. The beadlock comprises a first grip element and a second grip element. The first grip element is welded to the outer rim of a wheel. A bead of the tire is positioned over the first grip element. The second grip element has a plurality of rib elements angularly spaced around its periphery. The second grip element is secured to the first grip element such that the ribs grip the bead to hold it in place and secure the tire to the wheel.

Abstract: The present invention encompasses methods of reducing inflammatory immune cell activation and inflammation via inhibiting mitochondrial fission.

Abstract: The present disclosure encompasses methods of enhancing T cell longevity and/or T cell function by promoting mitochondrial fusion and/or mitochondrial structural remodeling including cristae. Compositions comprising the enhanced T cells may be used in adoptive cellular immunotherapy.

Abstract: A trencher boom sprocket having a hub body rotatable at an engagement point by the shaft, a plurality of teeth supported on the hub body, an excluder ring supported within the hub body on the first side, at least one O-ring provided between the hub body and the excluder ring and applying a spring-load to the excluder ring, a cap supported within the hub at the second side to substantially seal the second side of the hub, a bearing disposed between the shaft and the hub between the engagement point and the second side, and a spacer disposed between the bearing and the cap.

Abstract: A reference electrode including a water-impermeable, non-conductive substrate having a surface; an electrically conductive metal/metal salt mixture layer in contact with the surface; a water-soluble alkali metal salt layer; and a water-impermeable barrier layer overlaying a portion of the alkali metal salt layer and a portion of the metal/metal salt layer, and a method for preparing same are described. When the reference electrode is placed in a water sample to be tested, water enters the exposed portion of the alkali metal salt layer where it dissolves the salt forming a saturated solution in the region of contact between the alkali metal salt layer and the metal/metal salt layer.

Abstract: An apparatus used to excavate trenches. In a preferred embodiment the trenching machine has a cutting disc supported on a frame and adapted to operate with the center point of the cutting disc below ground. A spoils handler supported above the cutting disc and forward of the center point is used to move spoils away from the cutting disc. The ratio of cutting depth to weight of the trenching assembly and the cutting depth to wheel diameter is improved through the use of a cutting disc that is concave. The outer rim of the concave disc may support a plurality of replaceable cutting member. The cutting disc is rotated using a drive assembly that is contained within the cutting width of the cutting disc.

Abstract: A reference electrode including a body, a supply of flowable gel electrolyte, a wire electrode, and a tube for the electrolyte. The electrolyte is preferably contained in a cartridge within the body of the electrode and is capable of being dispensed into the tube in very small, metered, amounts, as needed.

Abstract: An injector device for a plunger-type pump of the type having one or more cylinders, an intake valve for each cylinder operatively disposed between the pump's low pressure inlet port and each of its cylinders and outlet valve(s) for each cylinder operatively disposed between the cylinders and the pump's high pressure outlet port, where the intake and outlet valves are held in place by removable threaded plugs which afford access to the valves so that they can be repaired or replaced. The injector device comprises a threaded plug member adapted to replace one of the removable plugs used to hold an intake valve in place, but also includes a longitudinal bore in which is mounted a one-way check valve. The inlet side of the check valve is adapted to be coupled to a chemical supply tank. Also, a restrictor is placed between the particular intake valve held in place by the injector plug and the pump's inlet port.

Abstract: A pipet for slurry and the like comprising a body with an end chamber containing a slidable element which, between them, defines a predetermined volume. The element includes an end plate to close the chamber, and a biased plunger is mounted in the body for moving the element so as to open and close the chamber and thus trap the predetermined volume of material to be sampled. The element is replaceable with one of different size to vary the volume of sample. In one form, a cutting edge on the body and a cutting surface on the end plate cooperate to sever fibrous material only partly in the chamber.

Abstract: A portion of a colorimetric liquid analyzer including a glass tube cell, a plunger mounted for reciprocation in the cell and having a passage to the cell, and a long liquid sample supply tube running from a body of liquid to be tested to the plunger passage. A "T" connector is provided in the tube and a pair of on-off valves which, together with the plunger, act to pump fixed volumes of fluid into and out of the cell. Means are provided to pump substantial air bubbles into the tube near its intake end, and the air bubbles are separated from the liquid through a vertical section of the T-connector so that only liquid is pumped into the cell. Preferably, acid is also added to the tube at its intake end to help dissolve particulate matter while the air bubbles continuously sweep the tube clean.
