Patent number: 11110868Abstract: A raising and lowering device for support of load, where the raising and lowering device includes a first beam, a second beam, and at least one profile element. Each of the first and the second beam is connected to the at least one profile element through at least one strut. One end of each strut is supported through a slide and pivot connection and an opposite end of each strut is supported through a pivot connection. The device further includes at least one synchronizing element rotatably supported at each end of the at least one profile element. The at least one synchronizing element extends in a loop substantially around the entire length of the profile element, to which at least one synchronizing element each of the first and second beams, via a bracket, is connected to such that the first and second beams are movable relative to each other between a retracted position and an extended position of the raising and lowering device.Type: GrantFiled: April 26, 2018Date of Patent: September 7, 2021Assignee: HPG ASInventors: Helge Åsteson Dimmen, Pål Bierman Jørgensen, Teo Raanaas Tandberg, Jens Harald Seiertun, Martin Gudem Ringdalen

Patent number: 5420183Abstract: The invention provides a substantially uniformly blended, flame retardant polypropylene composition and an extruded polypropylene sheet which comprises a polypropylene polymer, the bis(2,3-dibromopropylether) of tetrabromobisphenol A, antimony trioxide, titanium dioxide, calcium sulfate and distearyl pentaerythritol diphosphite. The invention further provides a method for producing such a polypropylene sheet material by forming a substantially uniform physical blend of the above components; drying the blend; heating the blend at a temperature above its melting point to form a melt of the blend components while mixing the melt; and extruding the blend through a sheet forming die and highly polished rollers.Type: GrantFiled: July 6, 1993Date of Patent: May 30, 1995Assignee: HPG International, Inc.Inventors: Arthur A. Arena, Parvin Sawhney
