A method of producing laminar structures, preferably consisting of fibreglass-reinforced polyester, which are free of air-pockets and pores, by spraying layers of the plastics and reinforcement fibres at a partial vacuum. The method may be carried out by an industrial robot. An airtight surface layer may be sprayed onto the laminate, whereby any pores or air-pockets collapse when the laminate is e...

The invention relates to a new antibiotic compound, acetyl erythromycin stearate having formula I The compound according to the invention is absorbed readily from the alimentary tract. Gastric acid does not convert the compound according to the invention to an uneffective form as is the case with some other erythromycin antibiotics. Absorbing is good also when the patient eats when tak...

In pressurized, gas insulated, high voltage switching installations with single or polyphase metal encapsulation, a switchgear section comprises several adjacent pressure tanks having gas tight partitions for accommodating the high-voltage switchgear and other current carrying parts. The number of encapsulation tanks is minimized by arranging the switchgear and current carrying parts belonging to ...

Apparatus for the discharge of fusible materials from a container under a pressure higher than the normal atmospheric pressure by compressed air of laboratory purity or compressed from fresh air, wherein a common tank (1) suitable for receiving the fusible material (8) and the compressed air, is connected to an assembly head (6) by a pipe nipple (9), where lock valve (2), a nozzle (3) and a spring...
