Patent ES-8104935-A1 (ES)
Title: Apparatus for cutting sheet material with variable gain closed loop
IPC: B26F1/38
Filed: 1980-04-09
Abstract: An apparatus for cutting limp sheet material with a rigid, cantilevered blade that is reciprocated as it advances along a cutting path through sheet material employs a load sensor to measure lateral loads applied to the blade by the sheet material during cutting. A load signal from the sensor is applied to the blade controls through a variable gain feedback circuit and causes the blade to be oriented slightly toward the side of the cutting path from which an unbalanced load is applied. The adjustment of the gain in the feedback network is made by means of speed sensors which measure the rate at which the cutting blade advances through the sheet material and adjust the feedback gain in inverse relationship.

Aluminum oxide formed during the reduction is extracted from the slag and passed on for melt electrolysis in order to recover the aluminum.
Patent ES-8200760-A1 (ES)
Title: Defroster for the evaporator of a refrigerator
IPC: F25B47/02
Filed: 1981-01-09
Abstract: The invention relates to defroster control apparatus for the evaporator of a refrigerator. A frost sensor for measuring temperature is mounted a predetermined distance from a surface of the evaporator which corresponds to the permissible thickness of frost layer. Control apparatus including a comparator circuit initiates defrosting when the frost sensor temperature falls below a reference temperature. In this construction the frost layer grows in the direction of the frost sensor which is swept by the surrounding air. During each operating cycle the frost sensor initially measures a temperature approximating to the surrounding temperature. As the frost progressively increases, this temperature falls because the air circulation in the vicinity of the frost sensor is progressively more influenced as the thickness of the frost layer increases. In the extreme case, the frost sensor can come into contact with the frost layer. Depending on the choice of reference temperature, defrosting can therefore be initiated when the frost layer screens the frost sensor to a predetermined degree from the surrounding air or has made contact with the frost sensor.

Title: Stack handling method and apparatus
IPC: B65B35/40
Filed: 1982-09-27
Abstract: A method and apparatus are disclosed for aligning the slices in stacks of sliced food products and for loading the stacks into container cavities. Stacks are received sequentially from a supply conveyor onto a stack support surface, where the stacks are detained either by friction with the support surface or by a stack catcher. A stack positioning member movable along the support surface pushes the stacks into engagement with a stack former for aligning the slices. Simultaneously, the stack positioning member retards movement of the next upstream stack on the supply conveyor so that the stack comes to rest on the support surface, and then pushes the previously aligned stack to a downstream pick-up station for loading into a container cavity. Each stack is removed from the loading station by a gripper assembly which pivots between the loading station and the container. Each gripper assembly has a plurality of pick-up fingers which may be spread to receive a stack at the loading station or to release the stack into a container. Each gripper assembly may also include a plurality of guide fingers of greater length than the pick-up fingers to extend downwardly and guide the stack into the container cavity. The pick-up and guide fingers are controlled by a rotary cam plate which engages the upper ends of the pivotally mounted fingers and, by incremental rotation, selectively spreads or closes the fingers.
