Patent ES-8205056-A1 (ES)
Title: Scraped surface heat exchanger.
IPC: F16J15/34
Filed: 1981-03-25
Abstract: A scraped surface heat exchanger is disclosed which includes a heat exchange cylinder and a vertically disposed rotating drum positioned within the cylinder having pivotal scraping elements on the periphery thereof for scraping the cylinder interior surface. The cylinder and drum define an annular product flow chamber through which product is pumped in heat transfer relationship to the cylinder. The heat transfer cylinder is surrounded by a thermally insulated jacket which in combination with the cylinder defines an annular flow chamber for circulation of a heat transfer medium to facilitate cooling or heating of product passing through the product flow chamber. The drum is mounted on a shaft which is journaled in a bearing at only one end, requiring utilization of only a single seal to seal the bearing from the product being heated or cooled. An indicator element integral with a carrier to which a rotating seal element is attached moves as the seal wears to provide a visual indication of seal wear. The carrier is designed such that the net product force acting on the carrier is in a direction tending to urge the relatively moving seal element together. Rotary agitating elements are provided at the inlet to the annular product flow chamber to distribute product, which is introduced at a single point, to the entirety of the inlet end of the annular product flow chamber. A mixing chamber located between the outlet end of the annular product flow chamber and the outlet of the heat exchanger is provided with cooperating stationary and rotary agitator elements to mix the product, thereby assuring uniform temperature distribution of product leaving the heat exchanger. A temperature sensor is mounted to the inner end of one of the stationary agitator elements to monitor the temperature of the material leaving the heat exchanger.

Title: Coin collecting mechanism
IPC: G07F9/00
Filed: 1982-01-20
Abstract: In a coin collecting mechanism for a coin operated apparatus with an inclined coin storage duct for coins of uniform size a pivotable mounted collecting arm (5) serves as support for a coin (3) in the collecting mechanism. The arm (5) is controlled by a relay- actuated operating lever (7) which comprises a stop projection (10) on its end nearest to the coin duct, said projection (10) only allows the passage of a coin from the duct when the mechanism is in its non-actuated position and which lever at its other end has a pin (11) cooperating with a curved track (12) in the arm (5). Said curved track (12) comprises a first track portion (13) which is so arranged and positioned that the arm (5) is locked when the pin (11) is positioned in said first track portion (13). Thereby it is achieved that the actuating relay must act on the operating lever with only a small force in order to release the locking of the collecting arm, said arm then being pivoted downwardly for collection of the coin, the gravity of which contributes to the pivotal motion of the arm.
