摘要:
A chain drive (1), in particular for a window, a flap or a dome light, comprising a housing (2) and an electric motor (8) which, by means of a transmission (9), drives a drive pinion (10) which is in engagement with a chain (5) which is formed from chain links and which is received in a retracted position in the housing (2) and can be conveyed, by means of the drive pinion (10), out of the housing (2) and can then be conveyed again into said housing through an opening therein, wherein a stripper which engages around the chain links of the chain (5) is arranged in the region of the opening on the housing (2), the chain links being able to be guided through said stripper. As a result, wet and dirt can be cleaned at least partially from the chain (5) by the stripper (20) when said chain is being retracted.

A vacuum insulating panel comprise a first sheet of a flexible material, a second sheet of a flexible material and a bridging element of a flexible material extending in a generally rectilinear waveform between the first and the second sheets. The bridging element and the sheets define therebetween a plurality of separate generally rectilinear evacuated compartments containing a self-supporting insulating element. The bridging element comprise first flat regions extending along the inside face of the first sheet, second flat regions extending along the inside face of the second sheet, and connecting regions extending between the first and second flat regions, There are seals between the flat regions of the bridging element and the inside face of the sheets. If one compartment is punctured only that compartment is affected. The seals prevent loss of vacuum in adjacent compartments.

Phenolic closed-cell foam comprises a hydrocarbon blowing agent and includes an alkali metal silicate in an amount of at least 1% by weight. The foam has an aged thermal conductivity as determined by the procedures of EN13166:2008 of less than 0.025 W/m·K. The foam is formed from a phenolic resole resin mixture having a water content of greater than 15% by weight but less than 24% by weight.

摘要:
A facade / wall system comprises a number of modules. Each module comprises a plurality of insulating panels (1) which have connection means on opposite sides thereof for interengaging the panels (1) together at joints (2) between the panels (1). Reinforcing elements in the form of top hat sections (3) bridge the joints (2) between adjacent panels (1). The top hat reinforcement elements used to interconnect adjacent panels in a module ensure that the composite panels act together as monolithic structure that creates a diaphragm whilst providing a surface to which cladding can be fixed and also providing a cavity between the panels and the cladding attached to the modules. They stiffen the panels and thereby enhance resistance to deflection. The reinforced panels create a wall that distributes its own self weight, as a diaphragm, to the points of no deflection, at the building columns. The modules are pre-fabricated and readily craned into position on site, allowing the building to be rendered weather resistant by mounting the modules in place from the inside of the building. The system is cost effective and relatively easy and quick to install.
