An assembly structured to clean the head portion of a stethoscope comprising a housing including a path of travel along which the head portion passes during cleaning. A supply of cleaning fluid is associated with a dispensing assembly which is cooperatively disposed relative to an activating assembly. The activating assembly is manually operated due to moveable engagement with the head portion as it travels along the path of travel. The activating assembly is thereby operatively positioned to activate the dispenser assembly when engaged by the head portion as it passes along the path of travel. The dispensing assembly delivers the cleaning fluid to an applicator assembly which distributes the cleaning fluid to the head portion and facilitates the cleaning thereof and removal of excess cleaning fluid there from.

An open-cycle engine in which rotary power is produced by the pressure of hot gasses against confined, rotating vanes.

A pig loader device can include a breech assembly having a chamber body, a ramrod compartment, a breech, and a neck. A ramrod having a push plate, a rod, and a breech plate may be disposed within the ramrod compartment and configured to slideably traverse the ramrod compartment and the breech. In use, the device can be connected to an ancillary pipe via the neck, and a pig may be placed within the breech and aligned be to be slid within the breech and neck upon engagement with the ramrod to facilitate pigging operations of a pipeline. The ramrod may then be forced forward to an extended position, thereby urging the pig through the neck to be seated within the pipe. The device may then be detached from the pipe to enable continued pigging operations.

The invention relates to intelligent injection molding equipment for vehicle part production. The equipment comprises a main body, a production chamber and a charging box, and further comprises a cleaning mechanism and a recovery mechanism; the cleaning mechanism comprises a lifting module and a cleaning module; the cleaning module comprises a driving chamber, a second motor, a rotating wheel, a swing rod and a cleaning brush; and the recovery mechanism comprises a recovery chamber, a crushing module and a stirring module. In the intelligent injection molding equipment for vehicle part production, the cleaning brush of the cleaning mechanism swings back and forth to sweep off accumulated materials on a nozzle to prevent influence on the injection molding effect, so that the product qualityis improved; compared with manual cleaning, the cleaning mode is safer and more efficient; wastes and the swept accumulated materials can be recovered and crushed through the recovery mechanism to achieve heating and melting; and through uniform stirring, the materials are thoroughly molten to achieve future reutilization, so that the cost investment is saved, and the practicability of the injection molding equipment is greatly improved.

The invention discloses a suction type conveyor belt surface cleaning device and method. A dust collection cavity is formed below an unloading roller of a belt conveyor, a dust collection notch in the width direction of a belt is formed in the top face of the dust collection cavity, a gap is reserved between the dust collection notch and the bottom face of the belt, the dust collection cavity is communicated with a dust collection fan, the lower face of the dust collection cavity is connected with a pollution collection container with the certain water storage volume, the pollution collection container is in a circular truncated cone shape, the diameter of a lower port of the container is larger than the diameter of an upper port of the container, a pollution discharge baffle is hinged to the lower port of the pollution collection container, and the pollution discharge baffle is tightly pulled or tightened to the lower port of the pollution discharge container by a tension spring or a torsional spring. According to the suction type conveyor belt surface cleaning device and method, the belt surface is thoroughly cleaned on the basis of the dust collection principle, removed coal slime is easy to concentrate, and no pollution is produced for the working environment; the device makes no contact with the belt, so that the belt is not abraded; the structure is simple, maintenance is convenient, management is easy, the labor intensity of cleaning of workers is lowered, and the purpose of safe and efficient cleaning is achieved.
