Title: Weft-yarn array for nonwoven fabric - comprising loops of yarn prepd. by transverse conveyor having dual guide-eyes
IPC: D04H3/12
Filed: 1982-02-08
Abstract: In a machine for the mfr. of non-woven fabrics wherein the weft yarns are secured on top of the warp sheet by adhesive, or welding, etc., the weft yarn array is prepd. by winding the yarns around a series of pins mounted on a moving belt on either side of the warp sheet. The weft yarns are laid around the pins on the warp-wise belts by means of a transverse moving belt carrying a series of guide-eyes. Each weft yarn passes through two guide eyes on this belt, which are sufficiently far apart to reduce the gross variations in the yarn offtake-rate caused by the direction-reversals at the end of a traverse. This arrangement maintains a more uniform yarn tension, reduces the breakage rate, and permits the speed of the machine to be increased.

Title: Concrete building blocks contg. polystyrene particles and strata - having strata interfaces wetted out prior to hardening
Inventor: PLUMAT MARC
IPC: E04C1/41
Filed: 1982-03-10
Abstract: Thermally insulating building blocks are constructed by partly filling an ooen mould with a wet concrete mix contg. dispersed particles of hollow insulation material (I), superimposing a slab of open cell expanded polystyrene with sufficient pressure for the underlying wet mix to penetrate into the expanded layer, and then covering the cellular slab with a further quantity of wet concrete contg. expanded filler particles which partly permeates into the top of the slab.
