Abstract: 1509502 Food treatment SOC DES PRODUITS NESTLE SA 2 Feb 1976 04004/76 Headings A2D and A2E  A process for the continuous impregnation of food pieces comprises immersing the pieces in an impregnation solution, said pieces being initially buoyant in said solution and passing the pieces together with the solution along a flow path to a separation zone wherein the solution flows downwards at a rate greater than the rate of downward flow of the pieces whereby those pieces which by absorption of the desired quantity of impregnant, have lost sufficient of their buoyancy to be carried downwards by the solution, and are thereby continuously separated from pieces of food that have absorbed less than the desired quantity of impregnant. The impregnating solution may be a brine or a syrup and the process is particularly suited to the treatment of fruit and vegetables. The process may be carried out in the apparatus shown in the accompanying Figure wherein food material and impregnating solution are passed into the top of tower 2 and move down the tower to the coniform base thereof. At the base, there is a mixing system in the form of a ring of jets around the tower. Pump 4 takes material and solution to separating plant 5, from which impregnating solution is pumped either back to the impregnating solution producing plant 3 or to the mixing jets. Food is transferred to storage vessel 6.

Abstract: 122,076. Caunce, R. B., and Gschwind, W. March 13, 1918. Strengthened fabrics with integrally-woven portions having crammed yarns.-Fabrics, specially applicable for aeroplanes, airships, &c., are woven with reinforcing ridges or ribs forming squares on one side of the fabrics and composed of yarns the same as or similar to those forming the ground of the fabrics. The ribs are formed by drawing- in extra warps and cramming some of the picks, and the reinforcing warps and wefts are bound in by intersecting them with ground wefts and warps at the same place as the nearest ground warp or weft, so that the reinforcing-threads slide over the ground threads and are hidden from view on the opposite side of the fabric. Thus, the reinforcing-warp b is bound in by the wefts c at the same places as the nearest body warp.
