Abstract: Several classes of in vivo carbon monoxide-releasing compounds are useful for the treatment and/or prevention of diseases, such as chronic inflammatory, e.g., rheumatoid arthritis, and of diseases with a strong inflammatory component, such as atherosclerosis, stroke, coronary disease, and Alzheimers disease. The in vivo carbon monoxide-releasing compounds can be attached to known drug vectors and/or known anti-inflammatory drugs, such as aspirin.

Abstract: An apparatus for charging a substrate including a dielectric substrate, a support member having a first end and a second end between which the member extends substantially parallel to the substrate, a row of electrodes distributed over the support member between the first and second ends, the electrodes extending from the support member in the direction of the substrate, the electrodes having a free end for spraying a charge on the substrate, each free end having a substantially fixed distance from the substrate, wherein the distance in the case of the electrode located at the first and second end of the support member differs substantially from the distance in the case of the electrode located in the middle of the support member.

Abstract: An ink composition for a meltable ink usable in a printing device in which ink drops are ejected from ink ducts, which comprises agents which reversibly cross-link the ink, the said agents containing a gelling agent. When an ink drop which has been transferred to a substrate passes over into a gel during the cooling process, the consequence is that the viscosity of the melted ink drop increases greatly so that the drops become relatively immobile. In this way the ink drops are prevented from uncontrollably flowing into the paper. As a result, inks of this kind are suitable for use on both porous and smooth substrates. In addition, these inks have been found suitable for use in a printing device in which printed substrates are subjected to thermal after-treatment.

Abstract: A non-invasive method and apparatus for in situ disintegrating calculi in the body of a living being employ electromagnetic radiation generated by a transmission antenna. The electromagnetic radiation is highly focused at the location of the calculus to be disintegrated. The transmission antenna is matched to the body medium by a suitable dielectric material.

Abstract: An x-ray diagnostic installation has a video display system connected to the output of an x-ray image intensifier, the video system including a subtraction stage with a weighting circuit connected to an image memory for suppressing image noise the subtraction stage also having a difference forming element for subtracting image information arising at different times. The output of the difference forming stage is supplied to a threshold circuit and the output of the threshold circuit is read into another image memory picture element-by-picture element. This memory is connected to the weighting circuit such that the output thereof controls the parameters of the weighting circuit picture element-by-picture element. A filter circuit may be interconnected between the output of this memory and the weighting circuit.

Abstract: An air-cooled, reciprocating piston, internal combustion engine has at least two adjacent cylinder barrels with a plurality of cooling ribs lying substantially perpendicular to the longitudinal axes of the barrels on at least part of the periphery thereof. The intake ports of the cylinder heads are located on the cooling air inlet side while the exhaust ports are located on the cooling air outlet side, and an air deflection cover overlies the cylinder barrels on the cooling air outlet side. The cylinder barrels are provided on the cooling air outlet side with cooling ribs lying substantially parallel to the longitudinal axes of the cylinder barrels. The air deflecting cover is of a configuration such that at least some of the cooling air flowing, in the area adjoining the crankcase, around and between adjacent cylinder barrels, is deflected toward these parallel lying ribs, so that essentially the total flow of cooling air supplied may be used to cool the hottest area of a cylinder barrels.

Abstract: The filter arrangement for an X-ray apparatus contains an X-ray source for emitting a diverging beam of X-rays and a filter plate positioned in the beam of X-rays. The beam is symmetrical with respect to a center beam axis. The filter plate which serves for attenuation of the X-rays before they impinge on a target is mounted on a pivoting axis. The pivoting axis is preferably arranged remote from and transverse to the center beam axis. By pivoting the filter plate about the pivoting axis into a selected position, a selected radiation profile can be obtained on the target. The rotatable filter plate can thus replace a plurality of wedge filters.
