Title: Radial shaft seal
Inventor: EMMENTHAL KLAUS-DIETER DR
IPC: F16J15/32
Filed: 1988-12-10
Abstract: To compensate for the effect of centrifugal forces on the sealing force of a radial shaft seal with an inner limb (1) and an outer limb (4) which are connected in the region of one of their ends (3), a flexible member (7) in the form of a washer precurved towards the connection (3) extends between the other end regions of these limbs (1, 4), and a fluid medium subject to inertia forces is provided in the enclosed chamber (8) thus formed. Under the effect of the centrifugal force, this medium attempts to force that area of the washer (7) which is at the greatest radial distance from the axis of rotation axially outwards. An additional radial force that compensates the reduction in the sealing force due to centrifugal force is thereby exerted on the inner limb (1). <IMAGE>

Title: Specimen relative moisture content measurer - is esp. for powdered material under construction site conditions, and extrapolates from values measured at intervals during heating
Inventor: GERHAEUSER HEINZ DR ING
IPC: G01N5/04
Filed: 1989-12-14
Abstract: The specimen is weighed by a weighing device which passes a wt. proportional electrical signal to an electronic control and evaluation unit. The latter computes the relative moisture content of the specimen by extrapolation from measurement values taken at time intervals during heating of the specimen. The control and evaluation unit derives an average value for the relative moisture content and additionally the measurment time required to determine the relative moisture content with a prederfined accuracy. The unit extrapolates each two measurement values using a decaying exponential fuction to determine the relative moisture content. ADVANTAGE - Enables relative moisture content of specimens to be accurately measured in relatively short times even under construction site conditions.
