Abstract: A pushchair has a frame comprising a pair of rear members, and a pair of front members having intermediate pivot joints which allow their upper and lower parts to pivot relative to one another between a first position in which they are in alignment with one another and a second position in which the pivot joints are displaced forwardly. A seat includes a seat portion which is pivotally secured to the front members of the frame and has its rear end pivotally connected to a pair of telescopic struts extending between the rear members of the frame and the junction of the seat portion and the backrest. The struts are at their minimum length so as to support the seat portion in a substantially horizontal position when the upper and lower parts of the front members are in their first position.

Abstract: A liquid composition for protecting a positively charged surface, the composition comprising: negatively charged polytetrafluoroethylene polymer resin particles and at least one member of the group consisting of methyltrimethoxysilane and an amino functional polysiloxane; whereby the negatively charged polytetrafluoroethylene molecules fuse to the surface upon exposure to ambient temperatures above about 68 degrees Fahrenheit.

Abstract: Disclosed is a paint sealant and method of applying the same to painted surfaces wherein a T.F.E. Teflon in a dispersion carrier is mixed with a fine abrasive in a dispersion carrier and heat is applied by buffing to burn off the dispersion carriers so as to produce a durable protective coating of Teflon.
