A vehicle washing apparatus includes a side track extending along a washing bay. A gantry is supported for reciprocal motion along the side track by a gantry motor. Sensors detect the front and rear ends of the vehicle to control movement of the gantry. A retractable carriage extends from the gantry across the washing bay under the control of a carriage motor and a vehicle width sensor. The carriage rotatably supports a spray bar for discharging cleaning fluid. A motor rotates the spray bar to s...

A disperser of washing agents is described, for a household washing machine, in particular a dishwasher, said dispenser (10) comprising a tank (12) for containing a liquid washing agent to which a visual control device (17-18) is associated, of the level of said liquid washing agent, said control device comprising a passage (18), placed between said tank (12) and the external part of the body (11) of the dispenser (10), and an element in a substantially transparent material (17) inserted in said...

A washer-jet verification master is employed to determine the correct alignment of washer nozzles within a production machine. The verification master includes a plurality of targets, which are preset to a first position. The verification master is placed in the production machine the water jets are actuated and if properly aligned will move the targets to a second position, which indicates proper operation.

An automotive vehicle washing system includes a frame comprising a bridge member end opposed and support sections mounted for linear reciprocating movement on spaced apart support rails. Pivoting washing nozzle support arms are mounted on the bridge section and are interconnected by a drive motor and drive pulleys to move in opposite directions to wash the sides and opposite ends of a vehicle. Each arm includes movable arm sections supporting spaced apart nozzle assemblies which may move toward ...

A system and method is disclosed for indicating satisfactory times for titrating a chemical solution, e.g., cleaning product, used by a utility device to clean and/or sanitize various types of articles. The utility device is described in an exemplary embodiment as being a warewashing machine that applies the chemical solution to articles provided to the machine on racks. The chemical solution is formed in a solution tank from a combination of at least one chemical product and at least one rinse ...

A cleaning station for storing, cleaning and replacing ostomy equipment. The station is mountable on a wall and is further adapted to be positioned over or in close proximity to a toilet. The cleaning station includes a cabinet, a countertop and sink, and a support adapted to support the cabinet on a wall. The sink is fitted with a drain conduit adapted for discharging waste from the sink to a disposal site. The support is adapted to extend laterally whereby the cabinet may be displaced outwardl...

There is disclosed a process for cleaning the interior wall of a metal vessel or pipe comprising flooding or turbulently impacting the interior wall of said vessel or pipe with a strongly alkaline or strongly acidic cleaning fluid, simultaneously measuring the conductivity of the cleaning fluid between two electrodes located in the interior of said vessel or pipe and terminating said flooding or impacting when the measured conductivity has been substantially restored to the level measurable with...

A device for preventing errors during semiconductor wafer fabrication can be configured to prevent separation of optical sensor unit components, such as a gas supply pipe and a fixing guide, that could be caused by excess N.sub.2 gas pressure. The device can also be configured to prevent excess moisture build-up that can lead to wafer sensing errors. The device includes a bath for receiving pure water or chemicals to remove particles. The bath can be further configured to discharge waste water a...

A contamination monitoring system having a portable framework which carries a rinsing bath for detachable connection to a remote fluid source. A transport structure is mounted on the framework to accommodate transport of the system to and from the remote fluid source. The framework includes a chamber which encloses the rinsing bath to isolate it from the surrounding environment, typically using a filter which removes unwanted particles from air within the chamber. The filter also typically creat...

An apparatus for processing a vibratory surface in which a processed object is hung on a hook, the hook is supported by the supporting frame having an air spring, the object is immersed in a surface treating liquid. The height of the air spring is automatically adjusted to the most suitable standard height in response to a weight of the processed object and then the surface treatment is carried out while the hook is being vibrated. An apparatus for performing this vibratory surface treatment met...
