A process and apparatus for welding together mating surfaces of two thermoplastic parts which have different melting temperatures. The process involves bringing the mating surfaces into contact with opposed heating surfaces of a heating device, which surfaces are heated by conduction from a single central heating element, separating the mating surfaces from the heating device, and then bringing th...

The durable products of prior art woodworking have always been unyieldi ng constructions of individual wooden elements held rigidly in place by rigid means such as joinery, fasteners, adhesives, or supporting structures. In the present invention a new method of mobile wood joinery alone is used to draw the wooden elements into place while yet allowing them a range of motion. The joinery of the pre...

A method for creating a push mechanism in a digital communication system comprises the following steps: creating a graphical object having associated therewith timing and positioning information, executing a first software application associated with the graphical object, wherein the first software application working in response to a predetermined event connected to the positioning information as...

When a backrest (12) of a seat (10) is pivoted, the centre of gravity of the person sitting or reclining in the seat (10) is changed. This results in the risk of the seat (10) together with its supporting frame tipping over when the inclination of the backrest (12) is changed. According to the invention, it is envisaged that when the backrest (12) of the seat (10) is pivoted, the seat surface (11...

Polyolefin films having incorporated therein a compound of the formula CH3CH2(CH2CH2)a CH2CH2(OCH2CH2)b OH, where a is 9 to 25 and b is 1 to 10, exhibit superior long lasting fog resistance. The polyolefin films are useful as packaging film for moist products and as a greenhouse film for agricultural applications.
