Title: Signal transmission systems - method and device for error recognition and correction for signals transmitted with statistical relations
Inventor: LIPPMANN REINER DIPL ING
IPC: H04N19/593
Filed: 1973-06-08
Abstract: Operation is with difference value transmission, and the scanned values of signal parameters are tested at the receiving end for an abrupt change of at least one scanned value with respect to at least one adjacent in space and/or in time scanned value, and/or to a value depending on such scanned values, and/or to a function depending on such a scanned value, and/or to a combination of such scanned vaoues. When such an abrupt change is detected, a number of following scanned values is tested for whether it satisfies specified criteria, and if the criteria are satisfied, the abruptly changed scanned value is suppressed and replaced by an adjacent, non-distorted scanned value etc. During reconstruction of the scanned values following the suppressed value, the replacement value or function, or their combination is taken as the basis, as in 2,250,019. When an abrupt change of a radient is detected, the gradients of a specified number of following scanned values of at least one series of values statistically dependent on the series of values to be tested is formed; if a specified tolerance limit is exceeded, at least a specified percentage of gradients is uses as a criterion for error testing.

Title: Cladding layer with chippings embedded in concrete - fibre reinforced concrete and chippings compacted in mould
Inventor: HOFFMANN OTTO
IPC: B28B19/00
Filed: 1974-10-03
Abstract: A decorative cladding layer for walls of buildings, consists of a base layer of fibre glass reinforced concrete, to which is applied a binding layer of sand and concrete without reinforcing threads, and in which is embedded a finishing layer of natural stone or marble chippings. In this method, the outer concrete particles are washed away from the projecting parts of the chippings. The finishing layer is applied to the base layer while inside a mould, and then compacted so as to obtain a good binding action. Rollers may be used for this compacting. Afterwards, heat can be applied to accelerate the setting of the concrete. The finishing layer can be applied in successive layers and excess material removed during or after hardening.

Title: Low pressure boiler for steam and hot water - has dryer for eliminating water droplets and mineral deposits in super-heater
Inventor: MOESCHLE JOSEF
IPC: F22G1/02
Filed: 1974-10-04
Abstract: The low pressure mobile boiler is used for generating steam or heat water. The boiler has a flame tube with a superheater which carries saturated steam. Formation of mineral deposits in the superheater is prevented and abrasive wear of superheater due to high energy water droplets is also eliminated. Upstream of the superheater (12) is arranged a heated drying chamber (21) with inlet (11) for the steam and outlet to the superheater. The drying chamber is arranged directly adjacent to the flue gas deflector chamber (5), of the flame tube (3). The water particles in the saturated steam are deposited and evaporated in the drying chamber so that mineral matter does not reach the superheater tube coils and the water droplets are evaporated.
