Abstract: A method for determining a state variable of a valve diaphragm of a motor-driven diaphragm valve includes the following steps: a) in a first time range: moving the valve diaphragm in such a way that the diaphragm valve changes from a first state into a second state; in the process b) detecting at least one reference value of a variable which is associated with the movement process of the valve diaphragm; c) in a second time range: moving the valve diaphragm in such the way that the diaphragm valve changes from the first state into the second state; in the process d) detecting at least one operating value of the variable which is associated with the movement process of the valve diaphragm; e) comparing the at least one reference value with the at least one operating value or variables acquired therefrom; and f) determining the state variable from the result of the comparison.

Abstract: The invention relates to a method for diagnosing a diaphragm valve having the following steps: a) providing at least one first quantity that characterizes a valve diaphragm, at least one second quantity that characterizes the diaphragm valve, and at least one third quantity that characterizes operation of the diaphragm valve to a determination device; determining a quantity that characterizes a current state of the valve diaphragm, in particular a current wear, from the first, second, and third quantities by means of the determination device by using at least one algorithm.

Abstract: A fiber product is described which includes fibers, a binder and a temperature control additive. The fiber product has properties that make it useful for a variety of applications. The fibers may be glass fibers and the product may be a fiberglass insulation product for use in buildings, vehicles, or other structures for acoustic and/or thermal insulation. The fibers may be cellulosic fibers and the product may be a wood board product. The temperature control additive is incorporated into the uncured fiber product to prevent deleterious self-heating during or after binder curing. The temperature control additive undergoes an endothermic process that consumes at least a portion of the energy generated during the exothermic curing reaction.
