Abstract: In the course of this method, an amount of expansible mixture is poured into a mould, after which the mould is obturated by means of a plug. A vacuum is created in the chamber of the mould by way of the plug so as to cause the foaming of the mixture. The vacuum is maintained for a period after the foamable mixture has filled the whole of the volume of the mould. At the end of the polymerization of the foamable mixture, the vacuum may be re-applied in the mould, preferably for several cycles, so as to cause the cells of the foam obtained to burst.

Abstract: A piece of furniture for sitting and lying, more particularly a sickbed, having a horizontal surface divided into head, central and foot portions. A stationary frame extends at least the length of the central portion and the head and foot portions are pivotally mounted on the stationary frame about horizontal axes so they may be adjusted to horizontal and inclined positions by shifting the weight of the user's body and can be fixedly positioned by locking devices. A spring device, such as a torsion spring, equalizes the weight of the user on the head portion and the spring device is adjustable to control the initial stress applied to the head portion. The central portion is pivotally connected to the head portion through a connection that allows for end play and provides for leverage so that as the head portion is shifted to an inclined position, the central portion automatically moves to a proper reverse sloping position to accommodate sitting.

Abstract: The process for producing a surface covering having a randomly embossed wear surface which comprises incorporating a blowing agent into a resinous composition, forming the resinous composition into a layer, heating to partially fuse the layer, printing a design on the surface of the layer, randomly distributing flakes of resinous composition containing an inhibitor for the blowing agent onto the printed surface of the layer, applying a clear wear layer thereto and heating the assembly to the decomposition temperature of the blowing agent.
