Abstract: A disposable liquid dispensing module in the form of a hollow plastic container for holding liquid, such as a cleaning solution or soap, has at least one liquid level sensing probe permanently mounted in it. The module is made to be inserted into a lavage machine or similar apparatus and includes a connector to which a connection plug having a liquid withdrawal pipe and connectors to the liquid level sensing probe is attached. The pipe is connected to an elongated flexible tube and the connectors for the liquid level sensing probe are connected to flexible wires, so that the plug including these components may be attached to the container outside the lavage machine in which it is used. When the level of liquid falls below a predetermined threshold, a signal is provided to the apparatus indicating that replacement of the container is to be made. The entire module then is withdrawn and the plug to the apparatus is disconnected.

Abstract: A method for washing an assay tray includes the following steps. A solid pad of absorbent material, such as a layer of cotton sandwiched between a cardboard and a nonwoven fabric, is firstly placed over the wells of an assay tray. The assay tray is then tilted or inverted together with the pad to allow the serum to drain off and be absorbed in the pad. The assay tray is then inserted in a washing device and submerged in the stationary washing liquid. Subsequently, the washing device is moved relative to the washing liquid to let the washing liquid flow freely in and out of the wells of the assay tray to thoroughly wash the beads and the wells, while the beads will be blocked from falling out of the wells by means of the special design of the washing device. The washing device has a broad opened wall which confines a network of ribs formed by intersections of transverse and longitudinal walls. The intersecting portions substantially superimpose the center of the wells respectively.

Abstract: The invention comprises an injection tank for cleaning boilers and heat exchangers. The tank is pressurized by connection to a potable city water supply.

The opened end is connected to a dosage device, the intake tip of the container part is removed and the EIA-rings are dispensed by means of the device.

Abstract: A paint roller cover having an outer annular absorbent layer is plugged at one end and inserted through one end of an open-ended cylindrical casing into a snug position within the casing. In one embodiment, said one end of the casing has a closure cap adapted for connection to a supply source of pressurized liquid for forced flow through the absorbent layer and discharge out of the other end of the casing. In another embodiment, said one end of the casing is insertable into piston-cylinder relationship with the open upper end of a container substantially filled with a cleaning liquid. Relative axial movement of the casing and container operates to force the liquid through the absorbent layer. An important feature of the invention is that during endwise movement of the cover into the cleaning position, the material of the absorbent layer will be angularly deflected into a position which is conducive to the uniform distribution of the axial flow of cleaning liquid within the annular layer.
