Abstract: A continuous process for producing pretzels is disclosed in which an essentially dry mixture containing flour, corn starch hydrolysates and salt is introduced into an extruder; water is injected into the extruder barrel to bring the water level of the mixture to between 19% and 25%; the material is extruded at non-cooking temperature to form a self-supporting ribbon of extrudate; the extrudate is sprayed with a caustic solution; and the sprayed extrudate is baked. The claimed process is adaptable to the continuous production of a filled pretzel product.

Abstract: The washing machine has a prewash chamber (11), a clear wash chamber (2), and a rinse chamber (3) in a tube (4). The chambers are separated from each other by separating walls (5, 6) having transfer openings. During the cycle period, which is defined by successive transfers of the laundry from one respective chamber (1, 2, 3) to the next, the rinse water in the rinse chamber (3) is changed more than once. The first rinse water is collected in a tank (47) and heated to the clear wash temperature during the cycle period. Before the end of the cycle the prewash water is drained from the prewash chamber (1) and the preheated clear wash water is filled into the prewash chamber (1). At the end of the cycle, the prewashed laundry together with the clear wash water passes into the clear wash chamber (2). This chamber can be heated via a steam connector fitting (43).

Abstract: An electronic control device for internal-combustion engines wherein the quantity of air taken in is decreased when the engine speed is greater than a target value, that is, when the deviation of the number of revolutions of engine is positive, with the engine in a slow-speed hunting state, and the quantity of air taken in is increased when the engine speed is less than a target value, that is, when the deviation of the number of revolutions is negative, or wherein the quantity of air taken in is decreased when at least one of the quantity of air taken into the engine, intake pipe pressure, and a value obtained by dividing the quantity of air taken in by the number of revolutions is greater than the target value, that is, when the deviation is positive, with the engine in the slow-speed hunting state, and also the quantity of air taken in is increased when it is less than the target value, that is, when the deviation is negative, thereby controlling the aforementioned parameters to their target values and acc

Abstract: An amplitude-adaptive vector quantization system intended for efficient signal coding and decoding. A mean value separation circuit (2) separates the mean value from an input signal which has been divided into blocks, and a tree-search vector quantizer (6) implements tree-search inner product vector quantization so that index information is truncated depending on the detected vector amplitude, thereby reducing the volume of information for transmission.

Abstract: A chisel for rotationally disengaging a threaded bolt, nut or screw, has at one end thereof a cutting edge for cutting into and penetrating a surface of the bolt. The chisel further includes a first chisel face terminating at the cutting edge of the chisel, and a stop face positioned away from the cutting edge with the first chisel face disposed between the stop face and the cutting edge. The stop face is at an angle of about 90 degrees or less with respect to the first chisel face. The cutting edge has a width that is about equal to or greater than the distance between the stop face and the cutting edge. The stop face prevents further penetration of the cutting edge into the bolt beyond the stop face so as to provide for application of rotational force to the bolt by the chisel without further penetration of the cutting edge into the bolt.
