  • Compensating filter for thorax x-ray photograph
    Patent number: 5355400
    Abstract: A device for compensating large absorption differences when photographing the thorax by means of X-ray radiation, whereby a compensating filter is placed close to the X-ray tube in the beam of the X-ray tube perpendicular to the optical axis of the X-ray radiation, whereby a support running in the direction of the optical axis is placed on the X-ray tube housing above the optical axis at an angle of 93.degree. to 105.degree. to the vertical, at which a filter holder, which can be displaced in the direction of the support, is arranged with the compensating filter, allowing optimum matching of the compensating filter to each patient.

  • Modular step exercise unit
    Patent number: 5354247
    Abstract: A modular step exercise unit includes a plurality of individual steps. Each step is in the form of a base having a horizontal platform which comprises the upper surface of the base with depending sides forming an apron which terminates in a plane parallel to the platform so that the apron can be placed directly on a support surface, such as a floor. The steps may be made of differing size so that during storage or even in certain use conditions, steps which are not being used can be stored within the periphery of the apron of the largest step. A multi-level step can be formed by mounting a smaller step on a larger step. The individual steps could be used abutting each other or spaced from each other to provide a multi-level arrangement which includes individual steps and the floor.

  • CMS/SiO.sub.2 /Al.sub.2 O.sub.3 catalysts for improved selectivity in the synthesis of amines from methanol and/or dimethyl ether and ammonia
    Patent number: 5354893
    Abstract: The present invention relates to an improved catalyst for the selective synthesis of monomethylamine (MMA) and dimethylamine (DMA) at the expense of trimethylamine (TMA) for a starting feed of methanol and/or dimethyl ether and ammonia. The current industrial catalyst for this process is a standard SiO.sub.2 /Al.sub.2 O.sub.3 material. The present invention combines this standard catalyst with microporous carbon molecular sieves (CMS) to form a composite material (i.e., a CMS/SiO.sub.2 /Al.sub.2 O.sub.3 material) with higher selectivity for the desired products MMA and DMA. The invention also relates to methods of making the improved catalyst and a process of using the improved catalyst material in the production of MMA and DMA.
