Abstract: A system for warning regarding the presence of manually attached grounding contacts (21) on high voltage conductors (3), comprises a) a naked additional conductor (1) close to the high voltage conductor (3), however spaced therefrom, and with an ability to be clamped resiliently to contact with the high voltage conductor (3) when the grounding contact (21) is attached; and b) a warning device (20) having connection means (4, 5) to the high voltage conductor (3) and to the additional conductor (1). The warning device has, in a part (24) arranged near the high voltage conductor (3), equipment for sensing whether the additional conductor (1) has been brought to contact with the high voltage conductor or not, and for transmitting a signal regarding this condition to another part (26) of the warning device which is remote from the high voltage conductor, preferably at ground potential. From this part (26) the signal can be transmitted to an operation central.

Abstract: The present invention relates to a process and an integrated plant to be used in the process for the preparation of synthetic fuel (synfuel) and production of electrical energy. A part of the energy produced is used for the operation of the energy requiring steps of the process, whereas the residual part is exported for other purposes. The warm exhaust gas from the part of the plant producing electrical energy is fed to a preheating step for natural gas being used as a starting material for the preparation of synfuel.

Abstract: A decal organization tool for products needing large numbers of decals utilizes a single large sheet on which all product decals for a specific product or product model are carried. The invention includes a means by which the previously unavoidable irregular margins surrounding the decals are effectively hidden from the eye and allows large sheet printing of decals with an aesthetically satisfactory overall appearance. An irregularly zone is added to the edge of each decal, and along with an ultraviolet responsive additive placed in the decal adhesive, allows the decal to form an indelible footprint on the product to which it is applied. The footprint, invisible to the eye, becomes visible under ultraviolet light, allowing identification of a specific decal and proof of its application to a product, even when the decal is no longer on the product.
