Removal of dirt from motor car bodywork - involves directing jets of air onto bodywork as it is rotated

The bodywork shell (B) of a motor car has any dirt on the bodywork surface removed before the bodywork is painted. The dirt is removed by passing the bodywork through a chamber (4) in which the bodywork is rotated about its longitudinal axis and at the same time sprayed with jets of air (41). A correlation is first established between the degree of dirt removal on the one hand and the speed of rotation of the bodywork and the rate of air flow on the other hand. The bodywork is then rotated at this defined speed. USE - Motor car mfr. Clearing dirt off bodywork before painting.

Ultrasonic cleaning apparatus and method

Analysis or disposal of surface adherents

A non-contacting method for removing substances adhered to a surface and either disposing of them or detecting and analysing them, involves a pressure chamber 9 supplied continuously with a clean gas through an inlet port 14. The gas escapes from the chamber through an annular orifice 10 thereby producing an annular wall jet 8 which when directed onto a surface 2 will flow along it with flow velocity components 16 directed radially inwards entraining removable substances from the surface 2. Opposing radial flow components 16 will on approach be forced away from the surface creating an axi-symmetric flow 17 away from the surface, enabling entrained substances to be transported from the surface 2 to a region within an exhaust port 18 isolated from higher pressure surrounding gas where transported substances may be detected and analysed prior to exhausting through an outlet pipe 19, or simply disposed of.

DESTATICISING AND CLEANING APPARATUS

Apparatus is disclosed for destaticizing and cleaning partially assembled items being transported on a continuously movable line, the apparatus comprises a housing which substantially surrounds the continuously movable line, static reduction apparatus which provides a static reduction zone within the housing, air input apparatus which provides air input into the housing, an air curtain through which the continuously movable line passes, and air exhaust apparatus which exhausts air from within the housing. The volumetric input of air provided by the air input apparatus is substantially equal to the volumetric output of air exhausted by the air exhaust apparatus so that substantially no movement of air occurs at the entrance to and exit from the housing. The air input apparatus removes substantially all dust and/or other foreign particles from the partially assembled items and holds them in suspension in the circulating air before being exhausted.

The device may include a fluid driven agitation device 80, such as a flexible ribbon or helically shaped blade. The fluid may be the stream exiting the nozzle which drives the agitation device.

Cleaning a vehicle sensor
