Abstract: A caster has a mount, a housing, a horn rotatable relative to the housing about a swivel axis, spaced apart forks on lateral sides of the horn, a wheel assembly disposed between the forks, a swivel locking ring disposed in the horn, and a braking member having a bridging portion and first and second plunger portions projecting away from the bridging portion. The bridging portion has a tooth rack extending outward. The first and second plunger portions project from the bridging portion in a direction opposite the tooth rack and have brake blocks. A brake lever arm is pivotally connected with the housing and movable between engaged and disengaged positions. An engagement pin extends through the housing and the interior of the horn and has first and second ends. The first end is connected with the brake lever arm, and the second end abuts the braking member bridging portion.

Abstract: A yarn feed module may be provided with four small diameter yarn feed rolls and a plasma treated yarn feed surface to optimize secure yarn grip for precise feeding by servo drive with greater durability and fewer yarn entanglements, utilizing a variety of threading configurations.

Abstract: Electronic devices that include a composition that can generate a gaseous oxidizing agent component; and a generating device configured to actively cause the composition to generate the gaseous oxidizing agent component. The generating device includes at least one metal-air battery that is in electrical communication with a power source that is configured to apply power to the metal-air battery according to a predetermined time interval to recharge the metal-air battery to generate the gaseous oxidizing agent component.

Abstract: A caster hub structure has an outward facing brake ring with a tooth profile on its outer surface. A brake block with a tooth profile on its outer surface is engageable and disengageable with the brake ring. The brake block material may be harder than the brake ring material, or the brake ring material may be hardness the brake block material, depending upon the application. The brake block tooth profile is configured to slip with the brake ring tooth profile at a first wheel rotational speed when the brake block is engaged with the brake ring, and the brake block tooth profile is configured to interlock with the brake ring tooth profile at a second wheel rotational speed when the brake block is in the engaged with the brake ring, the first speed being higher than the second speed.

Abstract: A caster comprises a body including a stem cavity with a stem of the caster rotatably mounted in the stem cavity to permit rotation of the stem relative to the body about a stem access. The stem may comprise a spline shaft extending from the stem into the stem cavity. The stem and spline shaft are operatively connected. The stem cavity may have a spline bushing. The spline bushing and the body are operatively connected to each other. The spline shaft and the spline bushing are releasbeably interlockable. One of the spline bushing and the spline shaft may be movable in a direction along the stem axis between the swivel position wherein the spline shaft is not engaged with the spline bushing, and a fixed position wherein the spline shaft is engaged with the spline bushing.

Abstract: A membrane electrode assembly may be made using a one-sided catalyst coated membrane (CCM) wherein only one catalyst layer, either the anode or the cathode, is coated directly on the ion-exchange membrane. In particular, a one-sided CCM may be used where it may not be practicable to coat both sides of the ion-exchange membrane with catalyst layers such as when PTFE is added to the anode catalyst layer to render it reversal tolerant.

Abstract: In a solid polymer fuel cell series, various circumstances can result in a fuel cell being driven into voltage reversal. For instance, cell voltage reversal can occur if that cell receives an inadequate supply of fuel. In order to pass current, reactions other than fuel oxidation can take place at the fuel cell anode, including water electrolysis and oxidation of anode components. The latter can result in significant degradation of the anode, particularly if the anode employs a carbon black supported catalyst. Such fuel cells can be made substantially more tolerant to cell reversal by using certain anodes employing both a higher catalyst loading or coverage on a corrosion-resistant support and by incorporating, in addition to the typical electrocatalyst for promoting fuel oxidation, certain unsupported catalyst compositions to promote the water electrolysis reaction.
