Abstract: ABSTRACT OF THE DISCLOSURE      There is disclosed a method of using an exhaust gas catalyst for treatment of exhaust gases developed by burning a hydrocarbon fuel or a fuel containing hydrocarbon and alcohol blends in an internal combustion engine.  These exhaust gases contain varying amounts of unburned hydrocarbons, carbon monoxide and oxides of nitrogen depending upon the operating conditions of an internal combustion engine.  This specification teaches a method of using an improved catalyst composition in which a support medium is provided for supporting the catalyst system.  This support medium has deposited thereon palladium and finely divided tungsten.  Tungsten is present on the support media in a quantity such that tungsten is available to substantially all of the palladium on the support medium.  In this manner, the palladium/tungsten combination is effective in the catalytic oxidation of unburned hydrocarbons and carbon monoxide and the catalytic reduction of oxides of nitrogen without production of significant amounts of ammonia when the internal combustion engine is operating under fuel rich conditions.

Abstract: A B S T R A C T         A color photoprinter having a scanning light source and automatic control of contrast excursion limits and exposure level is disclosed.  The printer is particularly well suited to contact printing with opaque image receiving materials.  A prescan of the original photographic transparency, only, is made to determine the initial exposure level and contrast excursion limits to be expected on the opaque receiving material, and to establish the required automatic exposure and dodging control signals.  The original is rescanned to generate signals which represent an un-sharp, luminous, contrast controlling mask.  These signals are retained in a memory, such as an image storage tube.  The opaque image receiving material is then moved into intimate contact with the original for the actual exposing scan, which takes place with the unsharp luminous mask electronically superimposed on the scanning light source, in order to provide automatic contrast and exposure level control of the image during the printing step.  The use of combined intensity and velocity modulation to shorten the exposure time for the color exposure scan when using insensitive reproduction material is also disclosed.

Abstract: A B S T R A C T           A construction set preferably toy set comprising building members and coupling members, in which the building members have specific geomet-rical relationships as to their length, width and thickness and all their sizes are dependent on a ba-sic size /a/ which defines the width of the basic elements. The said comprises elongated members with rounded end section, having a length being multiples of the basic size. The thickness of all elements is equal to a basic thickness. An appropriate number of throughgoing holes are defined in every member, and the distance of the holes from the end points of the elongated members is uniformized and it is generally the half of the basic size. The coupling elements are threaded bolts and nuts with an outer diameter for the bolts loosely sitting in the holes. Preferably the basic diameter of the holes is equal to the thickness of the elements which is about a quarter of the basic size.          By selecting such sizes a rather aesthetic appearance can be attained and the various members can be assembled in a practically unlimited number of con-figurations, thereby children' phantasy and creativity is largely improved.

Abstract: A b s t r a c t A Method for Measuring the Magnetic Nuclear Resonance For the purpose of limiting NMR spectroscopy to a selected area of a body the said area is prepared by applying first a homogeneous magnetic field passing through the entire body and superimposing thereafter upon the said magnetic field a first magnetic field of identical orientation whose strength varies in a first sense (first field gradient), exciting thereafter all the selected nuclear spins present within the body and in addition, selectively, only the nuclear spins present in a first body plane containing the volume element and extending vertically to the said first field gradient so that the selected nuclear spins contained in this body plane are returned to the direction of the homogeneous magnetic field while the nuclear spins outside this plane receive an orientation differing from the sense of the homogeneous magnetic field. This process is repeated twice, using each time a different gradient field, so that thereafter only the nuclear spins located within the volume element selected by means of the three gradient fields are parallel to the homogeneous magnetic field and can be excited by means of one or more pulses to obtain an oscilla-tion generating an induction signal. Residual signals having their origin in body areas outside the selected volume element can be eliminated if in two successive measurements excitation of the nuclear spins contained in the volume element or 1 the one hand and the rest or the nuclear spins on the other hand is effected for one of the groups always in the same phase and for the other group alternately in the same and in opposite phase so that when subtracting or adding the signals obtained in successive measurements the signals resulting from the rest of the nuclear spins are eliminated whereas the signals supplied by the selected volume element are added up.
