Abstract: A double-belt system for processing viscous melts includes a driven upper belt having a lower working run, and a driven lower belt having an upper working run spaced beneath the lower working run to form a gap therewith for receiving a viscous melt. A gap-adjusting mechanism includes upper rollers engaging an upper surface of the lower working run, and lower rollers engaging a lower surface of the upper working run. A distance between the upper rollers and lower rollers is adjustable to vary a size of the gap. A compensation mechanism is disposed over the lower working run to apply an upward force thereto for pulling the lower working run against the upper rollers, thereby resisting sagging of the lower working run. At least one delivery mechanism applies a temperature-controlled liquid across an entire width of the lower working run for controlling a temperature thereof. The liquid is extracted by an extraction mechanism disposed downstream of the delivery mechanism.

Abstract: This invention provides an improved system for monitoring and recording cell cultures. A method for measuring a delay period for an alternating current voltage applied across a pair of pins improves the stability of measurements made with the improved system. A method for applying a voltage across a pair of pins which avoids exceeding a pre-established voltage avoids the possibility of damaging and/or destroying cells while monitoring their culture.

Abstract: The invention is directed to a method and an arrangement for controlling the power of an internal combustion engine. A power adjusting unit or the air supplied to the engine is adjusted in dependence upon driver command. The mixture adaptation is improved for rapid changes of the driver command when the engine is cold and/or when the ambient air is cold by limiting the rate of change of the supplied air or of the position of the power adjusting unit.

Abstract: A method apparatus for selectively passing various types of telephony information between a data communications port on a digital telephone and a computer run application program. In one embodiment, the application program can select a subset of telephony events by way of a telephony command to the telephone's data communication port. This command is processed by a telephony command processor within the data communications controller which, in turn, sets a programmable event mask within the telephone. In response to the event mask being set, only the selected telephony events are spontaneously reported to the host computer and application program.

The apparatus includes a restoring spring which acts upon a first driver element connected to the operating element. Since the coupling spring is not subject to tension exerted by the restoring spring, the coupling spring can be embodied as relatively weak.
