Abstract: A dryer appliance includes an impeller assembly for drawing a fluid from a reservoir assembly and directing the fluid into a drying chamber to treat articles for drying. The impeller assembly includes a spindle that drives the impeller. The spindle is rotated by a roller which itself is rotated through contact with the dryer appliance's rotating drum. The reservoir assembly is filled with a clothing treatment liquid. Negative pressure generated by operation of the impeller assembly draws fluid from the reservoir through a siphon and the fluid is delivered to a fluid distribution element directed into the drying chamber.

Abstract: Portable, hand held, battery operated, hydraulic tools are provided with a tool frame and one or more interchangeable working heads. When the working head is connected with the tool frame, a piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task. The tool includes a sensor for detecting the type of head connected with the tool and a mechanism for adjusting the amount of force applied to the head by the hydraulic system based on the detected head type.

Abstract: A dispensing device for dispensing a foamable product. The dispensing device comprises a dispensing channel (110; 210; 410). The dispensing channel has: an inlet (111; 211; 411) for communicating with a valve-element (120) of a container (130) containing the foamable product; and an outlet (112; 212; 412) for dispensing the foamable product. The dispensing channel (110; 210; 410) further comprises a variable-volume cavity (140; 240; 440) at the outlet. The variable-volume cavity (140; 240; 440) is defined at least partly by a first component (142; 242; 442) and a second component (144; 244; 444) that is separate from and rigidly movably with respect to the first component to vary the volume of the variable-volume cavity (140; 240; 440) between a first configuration and a second configuration. In the first configuration, the variable-volume cavity (140; 240; 440) has a first volume and the outlet (112; 212; 412) is closed.

Abstract: A system and method of analyzing duct pressure within a pipe allows for monitoring and detecting vacuum pressure of gases. The system includes a pressure monitor and a target duct. The pressure monitor preferably includes an alarm light, a speaker, a sensing light, an alert indicator, and a battery alert. The method begins by periodically capturing a plurality of pressure readings inside the target duct with the pressure monitor. Each pressure reading is logged with the pressure monitor. Each pressure reading is compared to each situational alert with the pressure monitor to identify at least one matching alert for at least one specific reading. The matching alert is from the plurality of situational alerts. The specific reading is from the plurality of pressure readings. The matching alert is visually and/or audibly outputted with the pressure monitor, if the matching alert is identified for the specific reading.

Abstract: A washing machine appliance includes a wash basket rotatably mounted within a wash tub and supported by a front bearing and a rear bearing. A method of operating the washing machine appliance includes rotating the wash basket within the wash tub at a basket speed and obtaining first and second displacement amplitudes of the wash tub. Bearing forces at the front and rear bearings are obtained based on the basket speed and the displacement amplitudes. The determined bearing force at the front bearing is compared to a front limit. The determined bearing force at the rear bearing is compared to a rear limit. If the determined bearing force value at either of the front bearing or the rear bearing is greater than or equal to the respective limit, an operating parameter of the washing machine appliance is adjusted to limit bearing forces resulting from out-of-balance loads.
