Patent ES-8305911-A1 (ES)
Title: Method and means for removing heat from a heat storage layer of water
IPC: F28D20/00
Filed: 1982-05-21
Abstract: A heat storage pond, of the type having a lower heat storage layer of water covered by an insulating layer, has a partition that extends from a location on the periphery of the pond toward an opposite peripheral location, but terminates short thereof, for dividing at least the heat storage layer into two interconnecting portions. Water from the heat storage layer in one of the portions is drawn off and passed through a heat exchanger for extracting heat from the water. The water passed through the heat exchanger is then returned to the heat storage layer in the other of the two portions thereof, the partition effecting a physical separation between the intake and discharge. This arrangement sets up a circulation pattern in the lower region of the heat storage layer, while water in the other portion flows away from the point at which the cooler water is discharged into the heat storage layer, the only interconnection between the portions being in the region at the free end of the partition. Thus, the effective length of travel between the intake and discharge points is at least double the length of the partition.

Patent ES-8406859-A1 (ES)
Title: Cigarette filter
IPC: A24D3/04
Filed: 1983-02-16
Abstract: A filter for a cigarette includes a porous filter rod circumscribed by a non-porous or air impermeable wrapper, and ventilating air grooves embedded in the wrapped filter rod which extend from one end of the filter rod a preselected distance generally longitudinally of the filter rod. An air permeable tipping material circumscribes the wrapped filter rod which provides a path therethrough for ventilating air flow only into the grooves. The walls of each of the grooves defined by the wrapper, in one form of the invention, is permeable to air over virtually its entire length, and in another form of the invention is permeable to air flow only adjacent the mouth end of the filter. Under certain smoking conditions most, if not all of the ventilating air will flow from the grooves into the smoker's mouth through the open end of the grooves at the mouth end of the filter rod. Under certain other smoking conditions, at least a part of the ventilating air will pass through the air permeable walls, or portions thereof, of the grooves and into the filter rod wherein it co-mingles with and dilutes the smoke flowing therethrough.
