Abstract: Various aspects of the present disclosure are directed toward implantable medical devices, systems, and methods for cardiac assistance.

Abstract: A housing has a bud portion abutting an elongated stem portion. The bud portion is to fit within an ear. The bud portion has a primary sound outlet at its far end that is to be inserted into an outer ear canal, and abuts the stem portion at its near end. A speaker driver is inside the bud portion. Electronic circuitry inside the housing includes a wireless communications interface to receive audio content over-the-air and in response provides an audio signal to the speaker driver. A rechargeable battery as a power source for the electronic circuitry is located inside a cavity of the stem portion. Other embodiments are also described and claimed.

Abstract: A resin application apparatus used in the production of oriented strand board has a rotary atomizer supported within a drum for containing and tumbling wood flakes. A spinning cup is rotatably supported by a housing of the atomizer, with a gap formed between an outer surface of the cup and the housing. A supply line provides resin to the spinning cup for atomization thereof and coating of the tumbling wood flakes. A passageway is formed in the housing terminating in an outlet proximate the spinning cup. Solvent is flowed through the passageway and out of the outlet, sweeping away any accumulated material in the gap and on the spinning cup and housing. The cleaning operation is performed simultaneous with the flow and atomization of the resin, whereby the resin application process continues without interruption.

Abstract: An apparatus and process are described for homogenizing and subsampling process streams such as those present in the hot water extraction process for recovery of bitumen from tar sand. Such streams contain widely variable proportions of heavy oil, water, and solids. To obtain a representative analysis-size subsample from such a stream, a bulk sample is taken into a cylindrical open-topped vessel containing a coaxial cylindrical draft tube spaced from the internal wall of the vessel. A head element closes and seals the top of the vessel. An impellor extending into the draft tube through the head element is actuated to circulate the bulk sample along an elliptical flow path within the vessel. The vessel contents are maintained in a pressurized condition by the introduction of inert gas.
