摘要:
The invention relates to a portal washing facility for motor vehicles, in particular passenger motor vehicles, that includes a portal device that can move relative to the motor vehicle in its longitudinal direction, has at least one horizontal washing brush that is height-adjustable on the portal device, and at least one side washing brush that can move transverse to the direction of motion of the portal device. In order to have an effective, brushless high-pressure washing, in addition to washing with conventional washing brushes, at least one lateral high-pressure washing device is provided on the portal device and is used for high-pressure cleaning of the side surfaces and of the front and rear surfaces of the motor vehicle and can be driven along at least one traverse of the portal device transverse to the direction of motion of the portal device.

Methods and apparatus for plasma modifying a substrate are disclosed along with associated techniques for applying coatings to the substrate. Particular utility has been found using a hollow cathode to generate the plasma along with magnetic focusing means to focus the plasma at the surface of a substrate.

In this underbody washing device for motor vehicles, on a frame which is movable relative to the vehicle (F) in the latter's longitudinal direction (L) there are provided two pairs of spraying arms (3a, 3b; 4a, 4b) fitted with multiple spray nozzles, which arms are each pivotably disposed about a vertical pivoting axis (A1, A2) near to the ground on opposing sides (1a, 1b) of the frame. To the spraying arms (3a, 3b; 4a, 4b) are assigned actuating motors (6a, 6b), by means of which the spraying arms can be swung in under the base of the vehicle into their swung-in position running transversely to the longitudinal direction of the vehicle (L) and swung out into a second, swung-out position running parallel to the longitudinal direction of the vehicle (L). In addition, there is provided a control device (7) which detects the vehicle wheels (R) and acts on the actuating motors (6a, 6b), by means of which control device the spraying arms are drivable by the actuating motors in such a way that each of the spraying arms (3a, 3b; 4a, 4b) may be swung out from its swung-in position into its swung-out position before reaching a vehicle wheel (R), is held in its swung-out position while passing the vehicle wheel, and can be brought back into its swung-in position after passing the vehicle wheel.

The vehicle washing installation comprises at least one conveyor chain (1) in the form of a sprocket chain, by means of which the vehicles are moved through the installation, and a plurality of treatment units arranged along the path of movement of the vehicle for washing and optionally drying the vehicle. At least one of the treatment units is mounted in a carrier adapted to move forwards synchronously with the vehicle over a path length and to be moved back by means of a resetting device to its starting position. The carrier can be coupled mechanically to the conveyor chain (1) for the forward movement. The coupling device comprises a coupling member (8) which can be brought into direct engagement with the conveyor chain (1). The coupling member (8) is of comb-like form and comprises a plurality of teeth (8a) spaced in the longitudinal direction (L) of the chain at a distance (b) from one another, with gaps (8b) therebetween. The pitch (t1) of the gaps (8b) is an integral fraction of the pitch (t) of the chain studs (10). The gap width (b) in the longitudinal direction (L) of the chain is somewhat greater than the diameter (d) of the chain studs (10).
摘要:
A process for producing polymeric films by applying a liquid composition onto a surface of a substrate under vacuum conditions in a vacuum chamber. The composition has a first component which is polymerizable or crosslinkable in the presence of a sufficient amount of an acid; and a cationic photoinitiator which generates an acid upon exposure to ultraviolet radiation, electron beam radiation or both to cause polymerizing or crosslinking of the first component. A gas which emits ultraviolet radiation upon exposure to electron beam radiation is introduced into the vacuum chamber. The composition and the gas are exposed to electron beam radiation to cause the cationic photoinitiator to generate an amount of an acid to cause polymerizing or crosslinking of the first component. The composition is exposed to both electron beam radiation and gas-generated ultraviolet radiation and cured.
摘要:
A drying gantry for vehicle wash plants is proposed having at least one height-adjustable cross-beam to which a blower arrangement is attached for drying the surfaces of a vehicle over which the cross-beam moves. The blower arrangement is provided with a nozzle mouth arrangement forming a lower contour of the cross-beam, with the height position of the cross-beam being controllable depending on a desired distance between the lower contour of the cross-beam and the vehicle over which the cross-beam moves. The drying gantry is characterised in that the lower contour of the cross-beam in a region approximately corresponding to the middle of the vehicle width and on both lateral ends of the vehicle recedes towards the top, thus forming clear spaces.

In this method for washing motor vehicles in a gantry-type washing installation with two movable gantries, washing is performed with a single pair of vertical brushes which wash between two horizontal brushes and are located on one of the two gantries. During a forward movement of the gantries, the washing process is commenced with the first horizontal brush in the front third of the vehicle, while the nose is washed with the two vertical brushes. Then the nose and the top of the vehicle approximately up to the rear third of the vehicle are washed with the second horizontal brush. The direction of travel of the gantries is reversed as soon as the tail wash has been executed with the two vertical brushes and before the second horizontal brush has reached the tail of the vehicle. During the return movement of the two gantries washing with the brushes is continued until the vertical brushes have passed the nose of the vehicle and the first gantry is then stopped while the first horizontal brush is still in the area above the first third of the vehicle. By this method the washing time is shortened and the space requirement is reduced.
摘要:
A liquid composition and a process for coating the composition onto a surface of a substrate in a substantially oxygen-free atmosphere, under vacuum conditions. The composition comprises one or more components, all of which components do not go into a gas or vapor phase under the vacuum conditions. The composition has an ethylenically unsaturated component composed of an ethylenically unsaturated methacrylate monomer, or a combination of an ethylenically unsaturated methacrylate monomer and an ethylenically unsaturated methacrylate oligomer. The ethylenically unsaturated component is polymerizable or crosslinkable by the application of sufficient electron beam radiation. The composition is substantially absent of ethylenically unsaturated acrylate components, substantially absent of polymerization initiators, and substantially absent of solvents. The composition optionally further comprises one or more polymers without an acrylate functional group and without a methacrylate functional group. The composition optionally further comprises one or more of waxes, pigments, and/or wetting agents.
