Abstract: A process is provided for the preparation of Mn(II) chelates for use as contrast agents in magnetic resonance imaging, said process comprising reacting insoluble manganese (II) oxide with an aqueous suspension comprising a molar equivalent or molar excess of an insoluble protonated chelating compound conveniently at a temperature of from 20 to 50 DEG C. When the reaction is carried out with a protonated chelating agent in the absence of base, a precipitate of the protonated Mn(II) chelate is formed. A low osmolarity Mn(II) chelate solution can be formed from the precipitates by dissolving them in an aqueous solution of base. When the initial chelate forming reaction is carried out in a solution containing a molar equivalent or excess of base, a low osmolarity solution of the Mn(II) chelate is directly formed with most chelating agents. The Mn(II) chelate precipitates and low osmolarity solutions formed by the above processes are also aspects of this invention.

Abstract: According to the invention, in stuffing sausages in a string and for dividing into single sausages or into groups of connected sausages, it is possible to alter the division, regardless of the length of the sausages and the number of sausages connected in one group in a simple manner whilst retaining exact division, in that the division takes place by dividing elements which circulate in the direction of transport in opposite directions and synchronously on a circular path in each case and whose circulating speed is variable during their non-functional circulation, but is adapted to the sausage-transporting speed in the engagement region. The device required for this purpose is characterised in that the drive of the separating apparatus (25) is connected to an electronic or hydraulic control which regulates the rotational speed of the drive during circulation and comprises two drive shafts (19) which are arranged spaced-apart in parallel, are located in each case opposite the string of sausages, rotate synchronously in opposite directions, are arranged transversely to the direction of transport of the string of sausages and have in each case a dividing arm (20) projecting radially therefrom, which dividing arms interact by coming together during the dividing operation and thereby come into engagement in the manner of a serration with the respective constriction between two sausages.

Abstract: The seam ironing machine levels seam allowances on the inner surfaces of garments. It comprises a tension device (2) for the garments as well as two ironing rollers (3) facing each other and exerting pressure on each other under pre-tension; these rollers can move along the seam to be ironed, thus rolling-off on the seams, and thereby separate and iron the seam allowances smooth. The seam ironing machine replaces manual separating and smoothing of seam allowances to a large extent which, as a rule, can only be carried out on horizontal ironing supports and which moreover require a relatively large amount of space. The seam ironing machine is particularly suitable for the production of ready-made clothing for the efficient aftertreatment of seam allowances. <IMAGE>

Abstract: A technique for invaginating the esophagus (20) at the gastroesophageal junction (10) is disclosed, as well as an invagination device (70) useful in the described technique. The invagination device includes an introducer guide (75) which has an outside diameter approximating that of the esophagus and a plurality of needle-receiving lumens (78) extending to its outer diametric surface. The invagination device also has an engagement assembly which includes 10 needles (88), each having a retracted position in which they lie within the needle-receiving lumens of the introducer guide, and an extended position in which they extend out of the lumens and project radially from the guide for engagement with the esophagus at the gastroesophageal junction. The invagination device is introduced transorally into the esophagus, its engagement assembly is activated to place the needles in their extended position in engagement with the esophagus, and the engaged invagination device is advanced the toward the stomach to fold the attached esophagus beyond the gastroesophageal junction. A remotely operable fastening assembly (50), which has been introduced into the stomach through an operating channel/insufflation port, is then operated to fasten the invaginated gastroesophageal junction to the surrounding involuted fundic wall. Finally, the needles are retracted back into their needle-receiving lumens and the invagination device and the fastening assembly are removed from the body of the patient. This minimally-invasive technique accomplishes the formation of a new valve between the esophagus and stomach, thus preventing acid reflux.

The individual force meter comprises a flexural spring (10) as primary spring of an elastic reduction, and a further flexural spring (17) as secondary spring of the elastic reduction. A force transducer (18) with at least one perpendicularly oscillating cord is inserted between the center section (15) of the flexural spring (10) and the center of the flexural spring (17); this force transducer (18) measures the reduced force flow subject to the firmness of the flexural springs (10 and 17). The outside sections (13) of the flexural spring (10), for example, are connected to the frame (2), and the center section (15), for example, is connected to the chassis (1). The flexural spring (10) in the compression direction has a flat inertia ellipse, therefore in the transverse direction is substantially firmer than in the compression direction, and in contrast is relatively torsionally soft with regard to torques in the horizontal axis.

Abstract: Method for the automatic coordination of an independent intersection traffic light control device with neighbouring intersections. The traffic flowing therefrom is recorded and analysed, where, for a predefinable measuring time period (MZ) with a number (I) of time intervals (ti), the number (Z) of vehicles per time interval is determined and stored. The measuring time period is divided up into test cycles (Zy) with equal-length cycle time (TZ). Within the test cycles, the number of vehicles is added up for each associated time interval. Such a mapping of the total measuring time period onto a test cycle enables mean value and variance formation for these numbers. Mappings and variance calculations of this type are carried out for further test cycles with respective different cycle times. Since the size of the variance provides a measure of the cyclic characteristic of the traffic flow, an existing vehicle cycle and its cycle time are determined from the calculated variances for the coordinated control of the traffic lights. <IMAGE>
