Ultrasonic scanning of live animals and caracases particularly for grading, which scanning is preferably carried out on live animals to determine expected carcase composition, comprises use of an elongate scanning element along a line parallel to the lie of the spine. The method and apparatus enable data to be obtained for processing to identify thicknesses of the skin/fat layer and the muscle lay...

The chair frame is composed of a seat part (5) and a backrest part (6). Adjoining the knee-side end of the seat part (5) is a flexible spring joint (10) which is attached to the free end of a bearing arm (2) by means of a hinge (11). Attached to the backrest part (6) is a backrest strut (15) which is mounted by means of a hinge (18) on a slide (20) which is guided displaceably in a bearing arm (2)...

A laminated composite for administering fentanyl transdermally that consists of a fentanyl-impermeable occlusive backing layer (11), and an adhesive fentanyl reservoir layer (12) comprising fentanyl dissolved in an amine-resistant polydimethylsiloxane that has a high diffusivity and poor solubility for fentanyl which enables the fentanyl to be released rapidly from the composite over a one day per...

The strip of earth scraped up by the rotation bodies (3) is formed into a roll (6) which is then laid out to form a ridge. During the laying out process the scraping action is interrupted. The rotation bodies are driven, and the roll of earth is formed so that its symmetry axis is at right-angles to the direction of scraping. - To lay out the roll to form a ridge, the scraping unit is raised and r...

The invention relates to a method of manufacturing rotors of the kind having helical lands and intermediate grooves. A rotor body (2) is moulded or formed in some other way on a shaft (1) to only a small degree of accuracy, whereafter an outer layer (3) of polymer-based material is moulded on the rotor body to a high degree of accuracy. For the purpose of eliminating shrinkage-induced distortion o...
