Patent FR-2300669-A1 (FR)
Title: Floor, wall etc. coverings of foam-bonded fibres - and selected ground fabric zones impregnated with different resin mixtures
IPC: D06N7/00
Filed: 1976-02-16
Abstract: Foamed surface coverings are produced by impregnating throughout a large part of their thickness, definitely selected zones of a non-woven ground fabric, with >=1 mixt. of expandable resin, and then causing the resin mixt(s). to foam. The ground fabric is of glass fibres 'laid down wet', weighing between 35-70 g/m2, and bonded with a suitable thermo-setting resin. Some zones of the ground fabric are impregnated with a first mixt. of expandable resin, whilst some of the others are selectively impregnated with one or more resin mixts. the foaming characteristics of which are different from those of the first mixt. These zones outstanding, are impregnated with a non-foaming resin which is applied to the reverse face of the fabric from that on which the foamable mixt. is deposited, poss. after bonding to a film, so as to provide a reinforcement for the ground fabric. A quite thin floor covering can be produced which has the qualities normally associated with thicker and more expensive materials. Equilibrium of the surfaces prevents curling at the edges.

Title: Tubular insert manure mixer for watering hose - with choke and branch tubes connected to liq. manure container
IPC: B05B7/26
Filed: 1977-04-18
Abstract: Mixing device, for adding a liq. manure to a watering hose for horticultural purposes, consists of a tubular insert with a central choke; capillary tubes pass from eahc side of the choke to a can contg. the manure. The insert is fixed in the hose by the connectors and has a choke at its mid-point made by heat deformation. Capillary tubes are wedged into the insert, one on each side of the choke. Their other ends are wedged into the container, for holding the liq. manure, at the points. When water is flowing through the hose, it is slowed down when it reaches the choke so the pressure increases and causes a proportion to flow through one capillary tube into the reservoir. Some of the manure is pushed into the other capillary tube which takes it to the downstream side of the choke; the water leaving the insert is thus enriched with a certain quantity of manure.
