Abstract: ABSTRACT           A device for enabling a diver to determine his relationship to the true horizon in deep and murky waters or when physiological sensations are of little value is described.  An attitude sensor, incorporating a series of mercury switches, usually at the back of the diver's helmet or head, is coupled to a series of light emitting diodes equally spaced around the periphery of the face plate of the diving mask or helmet so as to simulate the natural observation that the half space above the horizon is illuminated while the half space below the horizon is not.

Abstract: ABSTRACT OF THE DISCLOSURE          .      Process for preparing supported catalysts to be used in heterogeneous-catalytical or electro-catalytical processes, by exchanging protons of acid groups on active carbon with cations from a solution of a compound of a catalytically active metal and separating the treated mass from the solution, characterized in that the catalyst is used in the medium of the reaction catalyzed by the catalyst, without separate reduction of said catalyst.  This process gives an active metal-on-carbon catalyst in which the metal particles are deposited as small crystallites, whilst avoiding cumbersome, known methods.

Abstract: ABSTRACT OF THE DISCLOSURE           Method and apparatus for testing wells where extremely high temperatures and pressures are to be encountered in the zone under test.  The apparatus provides means for testing and trap-ping samples of well fluid from the formation in the zone under test for removal from the well bore with substantial reduction in sample pressure at the ground surface.  The method permits confining the well fluid under test within the well bore near the zone under test to minimize the possibility of hazardous well fluids reaching the ground surface other than as trapped samples in expandable sampler chambers or otherwise safely con-trolled.

Abstract: INTEGRATED OPTIC DEVICE            Abstract of the Disclosure A solid state apparatus for and a method of (1) coupling a light beam to a dielectric waveguide, (2) modulating the intensity of the coupled, diffracted light beam, and (3) multiplexing the coupled, diffracted light beam within the waveguide to any one of several detectors.          The apparatus uses a liquid-phase epitaxially (LPE) grown film of bismuth substituted rare earth iron garnet to form a magnetizable layer in which stripe domains may be generated, sustained and moved about.  The stripe domains form a diffraction grating, the stripe domain width and orientation of which may be altered by the application of external magnetic fields. The altered stripe domains are, in turn, utilized to alter the coupling of the light beam to the waveguide and to alter the direction that the coupled, diffracted light beam is directed within the waveguide.

Abstract: Abstract of the Disclosure A shear-type cutting device comprises an elastic disc having a cutting edge which is pressed axially into engagement with the cutting edge of an opposing disc.  The elastic disc is rotatably mounted on one end of a bearing sleeve which is axially movable on a shaft.  The other end of the sleeve carries a lever arm upon which a pressure element operates to apply an axially directed force, this force being balanced by the reaction force between the two cutting discs.  The axial position of the cutting disc is un-affected by variations in this reaction force (or may occur when the opposing disc is struck) since such variations produce an unbalanced moment which causes the sleeve to bind to the shaft.
