Abstract: A blade set for an electrical knife comprises two parallel extending blades arranged adjacent with their inner faces facing and joined to one another. In use, for example, for slicing bread, the two blades are alternately reciprocated by the drive motor of the knife. Each blade has a series of indentations in its lower edge between which projecting teeth are defined. The tip of each tooth has a small concave notch, in the form of a circular arc, which extends between the edges of the tooth and which has a chamfer. The ends of this notch form two spaced points.

Abstract: In order to be able to fully automatically deposit a sausage strand (1) in turns on a smoking rod (2), the strand of sausages (5) reeled off a portioning device (4) with the aid of a rotating carrier finger (12) is first "wound up" on a feeder arm (14). This is done with the aid of a movable feeder device (18) of feeder arm (14), particularly and endless chain, and which in a preferred manner is provided with carrier teeth (22). During the retraction of the feeder arm (14) in the direction of arrow (25), the feeder device (18) is driven in the opposite direction. Thereby one turn after the other is transferred to the smoking rod (2) situated under the feeder arm (14). The smoking rod is situated on a rotating support (26), in which several smoking rods evenly arranged along the circumference can be exchanged with the aid of a delivery device (46), a transfer device (41) and a receiver ( 38). The removal of the loaded smoking rods is preferably done by hand.

Abstract: O A multi-jet print head for a continuous ink jet printer has its individual ink jets formed electrostatically instead of using a row of individual nozzles. lnk is supplied continuously through a slot in an electrically conducting body or to an elongated edge portion of such a body, while a strong electrostatic field is applied to draw off the ink as an array of parallel cusps. These break up at their tips to form a stream of ink drops which can then be deflected in known manner. The elelectrostatic field preferably has a reinforcing secondary field superimposed on it, which is cyclically varied at a suitable ink drop production frequency to synchronise formation of the ink drops at each of the cusp trips. This enables means for deflecting the drops to be synchronised with the moving drops for consistent deflections and corresponding optimum resolution. The use of a slot or edge portion reduces problems of nozzle clogging inherent in multi-nozzle arrays and the continuous ink flow provides uniform printing conditions along the length of the print head.

Abstract: A method for calibrating an adjustable frequency generator having a voltage-controlled oscillator which is preceded by a computer via a digital-to-analog converter. The control input of the oscillator is coupled to a calibrating device comprising a series circuit comprising a digital phase detector and a lowpass filter forming a phase-locked loop circuit arrangement. By the computer, a digital-to-analog converter is caused, upon a frequency reference value signal, to deliver a control voltage to the oscillator which corresponds to the output voltage of the lowpass filter prior to the start of the calibrating process. A digital value corresponding to the control voltage is stored in the computer together with a digital reference value corresponding to the given frequency.
