Abstract:
A cordless power tool has a housing which includes a mechanism to couple with a removable battery pack. The battery pack includes one or more battery cells as well as a system to dissipate heat from the battery pack.
Abstract:
In a cordless power tool system, high temperature gases created in a battery pack by the battery cells during a charging or discharging operation can be routed into a housing of one of an attached power tool or charger to reduce the temperature of the gases, prior to venting the gases externally. In an example, a battery pack has at least one vent hole for relieving pressure and a movable device covering the vent hole and configured to expose the vent hole upon a pressure set-point within the pack housing being exceeded. In another example, the pack housing includes a thin-walled section designed to break if pressure within the pack housing exceeds a given pressure setpoint. In a further example, the pack housing includes a baffle having an S-shaped cross-section for providing a vent path for gases and for preventing external fluids from entering the pack housing.
Abstract:
Disclosed are processes for the production of fluorinated olefins, preferably adapted to commercialization of CF3CF═CH2 (1234yf). Three steps may be used in preferred embodiments in which a feedstock such as CCl2═CClCH2Cl (which may be purchased or synthesized from 1,2,3-trichloropropane) is fluorinated (preferably with HF in gas-phase in the presence of a catalyst) to synthesize a compound such as CF3CCl═CH2, preferably in a 80-96% selectivity. The CF3CCl═CH2 is preferably converted to CF3CFClCH3 (244-isomer) using a SbCl5 as the catalyst which is then transformed selectively to 1234yf, preferably in a gas-phase catalytic reaction using activated carbon as the catalyst. For the first step, a mixture of Cr2O3 and FeCl3/C is preferably used as the catalyst to achieve high selectivity to CF3CCl═CH2 (96%). In the second step, SbCl5/C is preferably used as the selective catalyst for transforming 1233xf to 244-isomer, CF3CFClCH3. The intermediates are preferably isolated and purified by distillation and used in the next step without further purification, preferably to a purity level of greater than about 95%.
Abstract:
A control system for a bulk material baler embodied in a machine readable data structure and including an instruction to a moveable guide track to move from a removed position to a closed position to create a guide track loop around a volume of bulk material to be baled while that bulk material is under compression and also including in instruction to a bale strap feed drive to feed a pre-determined length of strapping around the guide track loop, and including an instruction to a cutter to cut the end of the bale strap and including an instruction to a strap fastener to fasten together the ends of the bale strap and including an instruction to remove the moveable guide track section from around the bale and an instruction to release compression and an instruction to eject a bound bale.

Abstract:
A panelized container system has a plurality of modular panels that are rigid and incapable of significant flexing. The modular panels assemble into a polygonal container for holding soil and growing plants through a plurality of openings in the panels. The panels connect by a union of female and male connecting members. Elongate connecting rods having trapezoid shaped appendages of 45-degree, 90-degree, 180-degree or combined orientation join elongate trapezoid shaped channels formed along the vertical edges of the panels. A selection of panels and connecting rods may be combined into a kit, which may include a tray.

Abstract:
The invention is a method of making a coated glass substrate having a low haze. A soda-lime glass substrate having at least one surface upon which a coating may be deposited is provided. The glass substrate is heated and maintained at a temperature sufficient to volatilize salts that may be formed during the depositing of a first coating on the glass substrate. A first gaseous precursor mixture including a halogen containing precursor, a metal precursor, an oxidizing agent, and an inert to carrier gas is directed toward and along the surface to be coated and reacting the mixture at or near the surface of the glass substrate to form a first coating containing a metal oxide coating. The glass substrate is cooled to a temperature to reduce crystalline growth in a second coating to be applied over the first coating. A second gaseous precursor mixture including a second metal precursor, an oxidizing agent, and an inert carrier gas is directed toward and along the coated surface of the glass substrate and reacting the mixture at or near the coated surface to form a metal containing coating. The glass substrate is cooled to an ambient temperature. The invention also includes a coated glass substrate produced in accordance with the aforementioned method.
