TRAGEKRAFTFREIES, FAHRBARES TRANSPORTGERAET

Magnetic core producing three dimensional field - has cylindrical laminated centre section and radially involuted outer section

Post-mounted flat roof substructure - has single size I=section joists bolted together into square frames with cantilever arms at each corner

Folding machine - for flat sheets, e.g. bed sheets

Floating water ski powered by leg movement - has array of shuttered, articulated blades presenting variable resistance to water

Angular position sensor. esp. IC engine ignition circuits - has permanent magnets mounted on shaft inducing twenty microsecond voltage pulse in stator coil

Decorative patterning of layered material e.g. fabric - is effected by pretreatment with adhesive under tension

Control for transverse mounted gearbox - has articulated linkage transforming single control shaft movement to sliding and rotational movement of receptor shaft

Safety unit for working at heights - has automatic set of cord clamping rings and manually operated set to give double safety action

Inflatable disposable umbrella - has plastics cover with ducts and nozzle with valve inflated by pump or gas cartridge

Fractionation process and machinery for green plants e.g. lucerne - allows separate recovery of juice and pulp in desired ratio, by grinding and bursting stems followed by separation of fractions

Rat trap with sprung holding plate - has base defining channel with slot in bottom through which holding plate passes when dislodged by rat
