Title: Improvements in apparatus for treating substances by means of the action of a fluid
IPC: C13B10/10
Filed: 1932-05-19
Abstract: 403,642. Making extracts from beet pulp &c. DELEMME, C. A., 3, Rue Daumier, Paris. May 19, 1932, No. 14286. [Classes 81 (i) and 127.] In apparatus for the extraction of juices from substances such as beet pulp, or for the extraction of substances from mixtures or compounds by solvents or chemical reagents, wherein the substance to be treated is contained in one or more cells arranged to be rotated, each cell is made up of two pockets off-set from the end of a connecting passage, into one of which pockets the fluid enters and from the other of which it is discharged, the relative shapes and sizes of the pockets and the passage being such that when a cell is filled to not more than about half its total capacity the treating fluid in passing through the inlet to the outlet is constrained to pass through the substance in the cell in all angular positions of the latter. The pockets and connecting passage may be so proportioned that in any angular position the substance to be treated completely covers either the fluid inlet or the fluid outlet or both, and so that during the rotation of the drum the whole of the substance is progressively projected into the passage, every part of it being progressively subjected to the action of the fluid. In the form shown in Fig. 2, the apparatus consists of a drum b comprising six cells a shaped according to the invention, and a common central duct c for the admission of the fluid. Each cell a is provided with a port f covered by a sieve h serving as an outlet for the treating fluid. The apparatus is also provided with a feeding and emptying door i in each cell. The fluid enters the cells through inlets e covered by sieves g. Each cell is made up of pockets a<1> and a<2> and a portion of restricted cross-section z. The circulation of the fluid may be in the direction shown by the arrows or, when the apparatus is enclosed in an outer drum, may also be reversed. A single cell a may in itself constitute the apparatus. In a form of apparatus for continuous treatment, shown in Fig. 5, each cell A of the drum is subdivided along the axis of rotation by a hollow partition y into which the treating fluid may be introduced so as to form a heating or cooling jacket, for example, in drying apparatus. The cells are similar to those shown in Fig. 2, and are similarly assembled about a common duct c having ports B communicating with the subdivisions of the cells, ports t being also provided in the partitions y. Alternate partitions y extend across the duct d but have a peripheral space d through which the fluid passes from one sub-division to the next, as shown by the arrows. The fluid then passes several times through the substance treated, while the substance travels from one sub-division to another continuously.

Thermoplastic material is continuously heat sealed by transporting said material to a zone of simultaneous heat and pressure to effect the seal in the form of a molten pool, preventing the parent material on each side of the seal from moving laterally away from the molten pool of the seal, continuously causing some of the material of the molten pool to be moved laterally to at least one edge thereof to increase the thickness and strength of the edge of the pool and transporting said material away from said zone of heat and pressure to allow the molten pool of the seal to solidify. The material 10 to be sealed is fed from the left of Fig. 1 between transporting bands 13 of cloth-like material or metal covered therewith and which pass around driven rollers 11 and idler rollers 12, e.g. of silicone rubber. Rollers 15 are provided to adjust the tension of the bands 13. Sealing bands 14 electrically heated by brushes 16 bear on the bands 13 to make an indentation in the molten pool of the seal to cause some of the material thereof to flow to the sides thereof. The patent material is firmly held by the bands 13 and so cannot move laterally away from the seal so that the molten material builds up at the edge of the seal. In a modification, Fig. 3, the sealing band 17 is bevelled to cause lateral movement of the molten material to one edge only of the seal. Examples are given of thermoplastic materials which may be sealed by this method.
