Abstract: A peanut butter press feeding mechanism has a peanut supply hopper which is controlled by a release gate to supply a volumetric feeder. The volumetric feeder ensures that each of four intermediate holding hoppers at a peanut butter press are filled to capacity. A second release gate controls the outlet of the volumetric feeder, which releases the peanuts into a totalizing scale which weighs peanuts supplied to all four of the intermediate holding hoppers. The totalizing scale supplies peanuts to a conveying arrangement having diverting gates which supply the appropriate intermediate holding hopper with a full supply of peanuts. During operation of the peanut butter press, a predetermined amount of oil is removed from the peanuts based upon the total weight of the peanuts used. This is necessary since merely knowing the volume of the peanuts used is insufficient due to the fluctuations in density of each batch of peanuts.

Abstract: A windshield wiper, in particular for trucks (lorries) and passenger automobiles, comprises a device for increasing the cleaning intensity which is determined, in known wipers, merely by the sweeping force of the wiping blade; this cleaning intensity-increasing device comprises one or several rotating brush rollers which are associated with the wiping blade borne by the wiping arm--of which blade there can be several arranged thereon. The brush roller can be oriented parallel, or at an angle, with the wiping blade. Or, the cleaning intensity-increasing device comprises a plurality of plate brush units and one or several rows of pinions in engagement with one another, or tangentially engaging friction wheels, serving as driving device for the said plate brush units. The plate brushes in the units have their bristles turned against the windshield and are adapted for being driven alternatingly in opposite senses of rotation.

Abstract: This cylindrical bale-forming press comprises sets of belts, bands or the like which define a chamber for forming a bale by rolling up crop products. At least one stationary roller drives the belts and is itself driven from a main drive shaft. Some of the guide rollers are movable and are subjected to a biasing action by hydraulic cylinders so as to maintain the belts under tension. According to the invention, a torque sensor is provided on the main drive shaft of the press and operates to provide an electrical output signal which is operatively connected to electrically responsive valve means in the hydraulic circuitry for controlling the hydraulic cylinders so as to reduce or eliminate the tension in the belts when an excessive resisting torque on the main driving shaft is sensed.
