Title: Method and device for measuring the thickness of a damp coating
Inventor: TAYLOR JAMES
IPC: G01B11/06
Filed: 1981-02-13
Abstract: In the method according to the invention, use is made of a device for measuring the thickness of a damp coating, e.g. a coat of paint on a substrate, a part of the device being a support which has two feet whose ends can be pressed onto the substrate through the damp coating. Built into the support is a probe or a sensor which can be adjusted with respect to the support. The respective position of the sensor can be read off on a scale. The sensor has a transparent or translucent free end, so that the point at which the sensor is brought into contact with the damp coating can be observed. In the method, calibration is carried out in such a way that the device is placed onto a surface which is not provided with a coating and which has the same shape as the surface bearing the coating; the result is to avoid wear of the device as well as errors ascribable to the curvature of the surface.
Patent DE-3121804-A1 (DE)
Title: Internal combustion engine for powdered fuels, especially coal dust
Inventor: SCHATZ BERTHOLD
IPC: F02B45/02
Filed: 1981-06-02
Abstract: In an internal combustion engine for powdered fuels with a combustion chamber, an inlet and an exhaust valve and a plunger, which is inserted into a cylinder so that it is slidably displaceable in a guide without contact with the inner wall of the cylinder, a diaphragm clamped at its edge, a bellows or an arrangement of disc spring-shaped parts assembled like a bellows being inserted between the combustion chamber and the plunger, the plunger (24) and diaphragm (18) are unconnected and the space (26) located between the diaphragm (18) and the plunger (24) is filled with liquid. Hence the expansion movement caused by the combustion in the combustion space and made possible by the elasticity of the diaphragm is transmitted to the plunger by way of the enclosed liquid. The diaphragm can therefore be deformed without rigid guiding in the type of movement most favourable for it by virtue of its design, with the result that its mechanical stressing is essentially reduced and it can therefore be manufactured from relatively thin and elastic material, which in turn makes dissipation of the combustion heat by way of the thin diaphragm easier. Furthermore, owing to the constant deformation of the diaphragm, no combustion residues can collect on it. <IMAGE>

Patent DE-3130450-A1 (DE)
Title: Device for drying material webs or sheets
Inventor: DOSDOGRU GUENAY DR ING
IPC: F26B13/20
Filed: 1981-07-23
Abstract: In known devices of this generic type, a compromise has previously always been reached with regard to the design of the slot nozzles on the one hand and the guide surfaces adjoining the slot nozzles on the other hand, as it was not possible to bring an optimum drying process into line with an optimum carrying action over the length of the drying path. The invention provides a device, in which the material webs (2) or sheets to be treated can be guided in a floating and virtually tension-independent manner. At the same time, an intensive and economical drying of the material webs (2) or sheets is possible even at high product speeds. This is achieved by the inner surfaces (12, 13) of the slot nozzles (3, 21) being arranged at given angles ( alpha , ss) to the guide surface (4, 26), by the inner edges (14, 15) of the slot nozzle mouth (16) being designed with sharp edges and by the end surfaces (17, 18) adjoining the longitudinal edges (14, 15) being arranged at an acute angle, at right angles or at an obtuse angle of at most 135 DEG  in relation to the inner surfaces (12, 13). The guide surface (4) can in this case adjoin the slot nozzle (3) directly or there can be provided in the guide surface (26) following the slot nozzle (21) an opening (31), through which additional air is drawn in by means of injector effect. With the design according to the invention, an impact-jet floating nozzle is produced, which optimally combines the advantages of a pure and simple impact-jet nozzle with those of a pure and simple floating nozzle. <IMAGE>

Title: Method for distinguishing SECAM colour television signals
Inventor: KOSAKA YOSHITERU
IPC: H04N9/64
Filed: 1981-09-18
Abstract: In a multi-system colour television receiver, SECAM colour television signals are distinguished by means of a discriminator which initiates the automatic switchover to SECAM mode if a SECAM signal is unambiguously present. The colour subcarrier is extracted by means of a gate circuit (8) from the back porch of each horizontal synchronisation pulse occurring. If the signal is a SECAM system signal, the extracted colour burst signal alternately has the frequency of 4.25 MHz and 4.40625 MHz with each line passing through. A band-pass filter (16), the pass band of which has a centre frequency which corresponds to a harmonic frequency of a colour subcarrier of the SECAM system, outputs an output signal to a frequency discriminator (18) which then outputs an output signal to indicate that the SECAM format is present when the filtered burst signal occurs with half the line frequency of the SECAM system. <IMAGE>
