Abstract: The microwave embolus detector is a device that employs microwaves to detect the presence of air emboli in a flow of paste, which is passed through a Teflon tube or hose, as these microwaves are absorbed to a greater or lesser degree by the paste itself but are not absorbed by air. The level of power received by the receiver is constant provided the flow is homogenous. However, when a bubble appears, diffusion takes place as air does not absorb the microwaves, thus the power received will alter as regards the full scale signal of the homogenous flow. Diffusion may also be caused by the presence of lumps.

Abstract: The object of the present invention is related to a machine for transporting and piling sheeting, especially designed for transporting and piling sheets of both magnetic and non-magnetic material such as aluminium, stainless steel, etc. The sheets, once they are cut in a press, are transported to the transport position at the start of the installation; from there they are lifted and transferred onto the piling and transport machine. These sheets move in suspension by way of a conveyer belt, the machine being provided with a double system for the suspension of the sheets by way of electromagnets assembled along the path the magnetic sheets move along and by way of a vacuum suction system, also assembled along the movement path of non-magnetic sheets of aluminium or stainless steel.

Abstract: The invention relates to a machine for cleaning injection nozzles which is mounted as an additional station in a glass gluing machine. The inventive nozzle cleaning machine can be mounted in a fixed or sliding manner in the machine assembly, depending on whether the nozzle is of the fixed or the sliding type. For cleaning purposses, the nozzle, which is covered with paper, is introduced intoa a penumatically-actuated clamping head. The nozzle is then rotated a series of times such that the putty or material on said nozzle is left on the strip of paper.
