Abstract: A vibrating beam force-frequency transducer has a flat elongate blade designed to be interposed between two elements for applying a longitudinal force to the blade. The middle portion of the blade constitutes two lateral beams which are separated by a gap and which are interconnected by terminal portions of the blade. The beams carry electrodes for setting the beams into vibration in the plane of the major faces of the blade and for measuring the frequency of vibration. The terminal portions have extensions parallel to the beams and directed towards the middle of the blade in the longitudinal direction. The extensions are arranged for connecting them to the elements in zones that are closer together than are the terminal portions.

Abstract: A switchable data rate ISDN terminal for group G.sub.4 facsimile operation s disclosed. A decoder in the terminal automatically responds to a hexadecimal 7F formed by an extra bit added to the HDLC communications-starting flag when a 64 kb/s system transmits a 56 kb/s communication. The decoder responds by causing a speed controller in the terminal to reduce the effective data transfer rate.

Abstract: An electro-photographic printing device has a development location where toner is transferred onto a drum in proportion to the amount of light charges on the drum and a transfer location where toner is transferred from the drum to a sheet of paper.

Responsive to a call for printing, data to be printed are stored in a memory. The heater is energized until a set temperature is obtained. Printing is initiated as soon as the set temperature is obtained. The blower is stopped after heating has been discontinued, after printing has been completed, until there is a new call.

Abstract: A circuit has two multiplier modules. Each multiplier module has at least one controllable potentiometer for adjusting the amplitude ratio between an output signal and an input signal of the module. The potentiometers have substantially identical characteristics and they are controlled in the same manner such that the amplitude ratios of the multiplier modules are substantially equal. One of the modules receives as its input signal the first signal to be multiplied and delivers an output signal that is proportional to the product of the two operands, while the other module receives as its input signal a reference voltage and as its output signal it delivers a feedback signal which is servo-controlled to a value that is approximately equal to the value of the second signal to be multiplied. The circuit is applicable to meters for electrical energy.
