Abstract: A bottle assembly has a bottle and a removable cap. The cap includes a nozzle and a vent arrangement. The vent arrangement can include a vent conduit that extends into an air cavity present at the bottom of the bottle assembly when the bottle assembly is inverted. The vent arrangement allows for pressure equalization within the bottom assembly in response to liquid being dispensed from the bottle assembly to permit high flow rates of the dispensed liquid without squeezing of the bottle.

Abstract: Electric lawnmowers comprise drive units and mowing units disengageably coupled to the drive units. For example, a drive unit can be disengageably coupled to any one of multiple mowing units (e.g., rotating mowing units, reel mowing units) collecting forming a mowing system. For example, each of the drive and mowing units may be equipped with corresponding mechanical-engagement structures that are configured to be disengageably coupled. Each mowing unit is equipped with its electric motor (e.g., for rotating the cutting blades or the reel of that unit). The electric motor may comprise an electric connector, which is disengageably coupled to the drive unit's electrical wiring. In some examples, each mowing unit can also form a liquid disengageable coupling for circulating a thermal liquid between the drive unit and mowing unit, e.g., for cooling various components of the drive unit.

Abstract: Electric lawnmowers comprise mowing-unit decks with fluid passages used for cooling batteries, power electronics units, and/or drive motors. Specifically, a lawnmower comprises a drive unit (with a battery, power electronics, and one or more drive motors) and a mowing unit (with a mowing-unit deck). The deck's fluid passage is fluidically coupled to the drive unit (e.g., the motor and power electronics). The thermal liquid is heated by the drive unit's components and cooled as the liquid passes through the deck's fluid passage. The mowing unit may be equipped with a pump (for circulating this liquid), which can be powered by an electric motor on the mowing unit. The same motor may be used for rotating the cutting blades. The drive unit may have an additional cooling circuit providing immersion cooling to the batteries.

Abstract: Clayware is produced by firing a composition containing clay and a boron-containing flux, wherein the flux is a synthetic alkali metal and/or alkaline earth metal aluminosilicate having the crystal structure of a zeolite and containing boron entrapped within that structure. The boronated zeolite flux can be prepared in a form in which it can be used directly in the manufacture of clayware, especially earthenware.
