A beverage carbonator constructed as a pitcher shaped pressure vessel which functions as a carbonation chamber and which has a water canister and a gas generation chamber removably positioned inside the carbonation chamber. Carbon dioxide is produced by releasing internally stored water from the water canister into a carbon dioxide generating chemical in the gas generation chamber and then the carbon dioxide passes into the carbonation chamber where it is dissolved into a liquid beverage.

A kit for assembling a toolbox adapted for installation in the back of a pickup truck, the kit containing: a preassembled upper section, an unassembled lower section, and fasteners for fastening the upper section to the lower section, when assembled. The interrelatable parts of the unassembled lower section include: a bottom panel, a pair of end panels, a pair of side panels, and four locking members. The end and side panels carry tabs for interconnecting with corresponding slots on the bottom panel. Adjacent side edges of the end and side panels have abutting locking channels which are slidingly interlocked by the locking members.

A cordless earth tiller has a housing mounted upon wheels and including a handle for guiding and controlling the tiller and tilting the same in a fore-and-aft direction. A power driven crankshaft disposed forwardly of the wheels carries a plurality of arms which depend from crankpins of the crankshaft and are provided at their lower ends with tines. Links are pivotally connected at one end to the arms and at the other end to an axle of the wheels whereby rotation of the crankshaft causes a tilling or cultivating motion of the tines. The tines sequentially impinge upon the ground in a substantially vertical direction and proceed through the ground at a rearward inclination to draw the tiller through the ground in response to rotation of the crankshaft. Modifications comprise the use of harrowing disks as wheels and the substitution of ice chipping tools for the tines, etc.
摘要:
A liquid mixing valve having a single handle for mixing hot and cold water which incorporates a pair of resilient, tube-like squeeze elements for water passage. A pair of cams, controlled by the handle through a linkage arrangement, restrict the cross-sectional area of the squeeze elements thereby regulating the hot and cold water flow rates.
摘要:
An automatic float-activated drain valve for a liquid reservoir used in the accumulation of condensable materials and other contaminants from pneumatic systems and the like. The float is connected by a flexible tether to a lever arm which opens a pilot valve when the reservoir fills with water and the float moves to the top of the reservoir. The pilot valve permits air pressure to flow to an actuator which opens the drain valve. The pilot valve is in communication with a check valve which releases air pressure into the interior of the reservoir to rapidly expel water through the drain valve when the pilot valve is opened.

A keyboard support assembly for a computer work stand is disclosed comprising a subplate (74) having a profiled opening (98, 100) along each side, and a keyboard support plate (78) residing on top of the subplate. A pair of pivotal locking devices (138) are attached to the underside of the keyboard support plate to depend into the subplate profiled openings, and to selectively engage against an underside of the subplate as the keyboard support plate is slideably re-positioned thereon. The locking devices (138) include gear teeth 140 which engage with a gear rack segment 102 along the subplate underside.
