A sight means, particularly for weapons and other objects which are intended to be sighted onto a given point, comprises two mutually spaced and two mutually parallel grid discs (3,4) each of which includes a transparent disc provided with concentrically lying opaque grid lines separated by transparent interspaces, and which grid discs (3,4) are arranged in a tubular housing (2). In accordance wit...

A method for determining the spatial distribution of an NMR responsive element in a selected volume of an object to be examined and the relaxation time in the rotating frame (Tl rho ) of nuclei of the element. An external magnetic field is applied to the selected volume of the object. The nuclei in the selected volume are excited by a first electromagnetic pulse for generating a nuclear magnetiza...

Described herein are a capacitive pressure detector, with an electrically conductive substrate (1), an electrically conductive, plate-like member (3) disposed at a distance from the substrate, and an electrically insulating layer (2') hermetically bonding together the substrate (1) and the member (3) such that a capacitor chamber is formed between the substrate (1) and the member (3), as well as a...

Pearlescent dispersions consisting of a fatty acid glycol ester, a fatty acid alkanolamide, one or more surfactants of the formulae in which the individual symbols of these formulae have the meanings given in the description, salts and water in the amount to make up to 100%. Pearlescent dispersions based on these surfactants have the advantage that they alre...

Overheating alarm for surveillance of heat emitting objects, preferably intended for surveillance of hotplates and electric cookers. Emitted heat radiation from a monitored object is detected by an IR-detector, located at a distance from the monitored object, which transmits a warning signal and/or interrupts the electric current supply when the temperature for a monitored object exceeds a predete...
