Pouch containers that are in the process of being filled can advantageously be sealed using ultrasonic welding techniques. Ultrasonic welding produces effective seals in areas which have become coated with the substance flowed into the pouch. Further, the pouch containers which are sealed by ultrasonic welding can be severed one from the other using the ultrasonic sealing units to sever the film a...

The invention relates to an overload safety device for plough legs, in which the beam and its pivot joint are arranged on the plough frame in a common horizontal plane, with a working accumulator arranged in a tubular beam and with a toggle-lever system fastened between the plough frame and the beam. The object of the invention is to provide a compact and functionally reliable overload safety devi...

The clinical thermometer is comprised of an input from a signal conditioner, which signals are generated by a sensor consisting of a negative coefficient resistance arranged to remain in contact with an area of the human body, a signal translating stage which is comprised of a capacity-resistance load network; a microcontroller which receives the information from the prior stages without having to...

A device for cyclically rearranging a stack of rectangular sheets may fail due to uncontrolled displacement of an individual sheet to be exchanged. To avoid such malfunction, the device includes springs (200a, 200b) which maintain alignment of that individual sheet with thrust-supporting stops (66). The stops may be designed to sense the thrust to which the individual sheet is subjected so as to p...
