A smoke exhauster includes a housing having one or more orifices each for receiving an oil cup, and a catching device for catching the oil cup to the housing when the oil cup is moved upwardly relative to the housing, and to release the oil cup from the housing when the oil cup is moved upwardly relative to the housing again. The catching device includes a follower slidably received in a container, and a grasping device for grasping the follower to the container when the follower is moved upwardly relative to the container, and to release the follower from the container when the follower is moved upwardly relative to the container again. The housing has one or more windows for viewing the oil cups.

A smoke exhauster includes bottom opening for engaging with a fan device and includes a fastener secured beside the opening. A net device has a portion secured to the smoke exhauster opposite to the fastener and includes an ear having a notch for engaging with the fastener and for allowing the ear to be secured to the smoke exhauster without disengaging the fastener from the smoke exhauster. The ear includes an oblong hole communicating with the notch for allowing the fastener to be engaged into the oblong hole.
摘要:
A self-contained cleaning system for smoke exhausters comprising a bowl-shaped housing partially filled with cleaning fluid, and a sprayer tube rotatably secured in a central position within the housing having an upper portion and a lower portion. A plurality of upwardly aligned spout tubes are radially disposed on the upper portion of the sprayer tube, with the lower end of the sprayer tube having a beveled entrance and crescent-shaped apertures formed in proximity thereto. The housing can be mounted under a fan opening of the smole exhauster by engaging securing appendages therein with a wire grid grill covering the fan opening, and the upper end of the sprayer tube coupled to the hub of the fan by a coupling provided thereon. Upon the actuation of the fan, the rotatiton of the sprayer tube causes cleaning fluid to be drawn up the interior thereof, through the entrance and apertures on the lower portion, and to discharge from the spout tubes to clean the fan and parts of the smoke exhauster in communication therewith.

Indolinone compounds of formula (I) or (II): wherein A, R1, R2, R3, R4, R5, R6, R7, and n are defined herein. Also disclosed are methods for decreasing the activity of a protein kinase and for treating a protein kinase-related disease, such as cancer, with these compounds.
摘要:
A smoke exhauster includes a housing having an inclined plate extended forwardly and downwardly from an upper panel of the housing, a fan casing includes an upper panel secured to the upper plate of the housing to support one or more motors or fan devices, and includes a cut off portion formed in the front portion to receive the inclined plate of the housing and to allow the fan casing to be disposed forwardly relative to the housing, The fan casing and thus the fan device are disposed forwardly relative to the housing for allowing the fan device to effectively draw smoke or the like.
摘要:
A fan device for a smoke exhauster includes a housing having an upper plate and a lower plate, and the upper plate is secured to a motor and rotated by the motor, the lower plate includes a bore to allow an air to flow into the housing of the fan device, and a number of fan blades secured between the upper plate and the lower plate and each fan blade include a curved bottom edge to allow the air to flow into the chamber of the fan device before contacting with the fan blades, and the fan blades each include a number of orifices for reducing a noise generated by the fan blades when the fan blades are rotated relative to the motor. The fan blades are preferably disposed inclined relative to the upper plate and the lower plate.
