PURPOSE:To prepare easily chipping-resisting paint film having a good appearance and a suitable thickness to the car body by sticking chipping-resisting paint previously formed in a sheet form under an uncured state to necessary sections and heating it. CONSTITUTION:Chipping-resisting paint 4 is stuck on a release paper 3 so that it can be peeled easily and formed in the sheet form. This is stuck ...

Tyre building apparatus in which a former (20, 35) is mounted on a first rotatable turret (10, 12), and a component carrier (30, 51) of tubular form is mounted on a second rotatable turret adjacent the first turret. The former and the component carrier are arranged to be relatively movable at a turret station to enable the former to be surrounded by the component carrier so as to permit transfer o...

A vehicle guidance system for a tractor has a horizontal scanning laser on the tractor and a target arranged to return the laser beam along its path. When returned laser light is detected, indicating alignment of the beam with the target, the angle of the beam relative to the tractor axis illustrates the steering correction required. The target has an array of beam reflecting elements patterned to...

The invention relates to stabilizer-containing reactive components for the production of polyurethane foams having little or no tendency towards core discoloration which are characterized by a stabilizing addition of monomeric and/or oligomeric derivatives of the diphenylamine series, including the phenothiazine series. The invention also relates to new stabilizers of the diphenylamine and/or phen...
