A management device simultaneously clamps both the power cord and the vacuum tube of a floor preparation machine to appropriately direct the power cord and vacuum tube and protect from damage the power cord, vacuum tube cord plug and machine socket associated with the power cord and fitting associated with the vacuum tube.

A re-circulatory blasting device obtained is capable of performing stable treatment for a prolonged period of time even in cases in which an elastic abrasive employed has abrasive grains adhered to the surface of elastic cores. An elastic abrasive regeneration device provided to the blasting device regenerates elastic abrasive employed for re-circulation. The elastic abrasive regeneration device includes a mixer and a combining unit. Recovered abrasive fed in from an abrasive recovery section is mixed in the mixer with abrasive grains fed in from an abrasive grain feeder, and the abrasive grains are adhered to the surface of the cores of the recovered abrasive. In the combining unit, the abrasive grains are pressed against and combined to the surface of the cores by passing an aggregated state of the recovered abrasive mixed by the mixer along a constricted flow path having a flow path cross-sectional area that gradually narrows.

Invention is a cleaning assembly for cleaning a tire curing mould comprising a turntable (20) mounted on a base plate (12); a cleaning arm (50) extending on the turntable (20) in a movable manner and configured to blow dry ice, and an insulation hood (60) surrounding the cleaning arm (50) wherein the base plate (12) is having an adapter support (16) configured to be gradually widen or narrow for being adapted to the insulation hoods with different diameters on the base plate.

Invention is a cleaning machine for tire curing sidewall (80) that comprises a basket (10), a rotational base (20) which mounted into thereof, a nozzle (60) provided in a movable manner on the rotational base (20), of extending towards the open side of the basket (10) and having an intake (63) connected to inlet (62) in a fluid transferrable manner. The cleaning machine comprises a rotating joint (40) which mounted radially to the outward direction on the rotational base (20) and a telescopic arm (50) which carrying the nozzle (60) at the free end thereof and which of fastened on a rotational base (20) with the rotating joint (40).

An air wash abrasive particle separator apparatus which separates contaminants from previously-used abrasive particles contained in a contaminated abrasive particle mixture such that the abrasive particles may be re-used multiple times, the apparatus being in combination a contaminated abrasive particle mixture delivery device, an accumulator hopper assembly, a volume sensing device, an automatic flow control valve, a separator assembly and an air transfer device.

A high pressure pump including a linear actuator having a servo motor to axially rotate a hollow rotor shaft in alternating directions, the servo motor having a stator positioned co-axially around the hollow rotor shaft with an interior of the rotor shaft being co-axially coupled to a drive member to convert axial rotation into reciprocal displacement, the drive member being constrained against linear movement and supporting a shaft. At least one piston is coupled to the shaft and the piston is arranged within a cylinder to define a pumping chamber, whereby alternating rotation of the rotor shaft causes reciprocal linear displacement of the piston to pressurize fluid in the pumping chamber. A drive mechanism includes a controller coupled to a servomotor and an encoder to measure movement of the hollow rotor or output shaft and send a feedback signal proportional to the movement to the controller.
