Abstract: The invention relates to a process for repairing railway fastenings on wooden sleepers. After removing the old sleeper screw, which becomes loose in the course of time due to rotting of the wood, a thread is cut into the passage holes (11) of the ribbed sole-plate (2). New sleeper screws (33) with a single or double thread (37, 39) having a greater volume than the thread of the old sleeper screw are screwed into the boreholes (11) of the sleeper (1). One thread (37) of this single or double thread (37, 39) has a larger outside diameter that the passage hole (9) of the ribbed sole-plate (2). This thread (37) is matched to the thread (30) cut into the ribbed sole-plate (2). To permit simple guiding of the new sleeper screw (3) into the borehole (11) of the sleeper (1), the old cut-in thread (12) is used for guiding a thread cutter when cutting the thread (30) into the ribbed sole-plate (2) and for the new sleeper screw (33). Fig. 6 is intended for the abstract. <IMAGE>

Abstract: The greyish black occlusion pigments according to the invention, which are based on zirconium silicate as occluding substance and carbon black particles as occluded phase, are prepared by calcining a mixture of zirconium dioxide, a source of silicon dioxide, the carbon blacks and mineralisers under reducing conditions at 900 - 1400  DEG C. The process is characterised by the use of zeolites having an SiO2/Al2O3 molar ratio of greater than 4, preferably greater than 10, as SiO2 source. By including a coupling agent, in particular a silicone oil, it is possible to increase the depth of shade. The use of zeolites makes it possible to use different zirconium dioxide grades and the preparation of pigments having a higher carbon black occlusion rate.

Abstract: In an arrangement for the regenerative braking of electronically speed-controlled three-phase AC motors, there flows in a bridge circuit for each phase a control alternating current which is in a suitable angular position and is modulated by a transverse control direct current, which is not influenced by it, in such a way that control alternating current half-waves are steplessly shortened. These shortened control current half-waves are used after suitable conditioning to drive a three-phase inverter, to be precise to resupply the electrical energy available as direct current in a buffer store by virtue of generation from a three-phase AC motor into the public three-phase mains. The arrangement is undertaken in such a way that a continual transmission of the available energy that is to be resupplied is performed. The arrangement is constructed such that it does not interfere and is not subject to interference. <IMAGE>

Abstract: A hockey stick (1) comprised on a head (2), a stem (3), a handle (4) and a bead (5) showing a division between the parts 3 and 4. The stem (3) includes a slot (6) substantially between the bead (5) and the head (2). The hockey stick is formed by injection moulding a foamed thermoplastics material, usually glass fibre reinforced nylon, such that the density through the head and stem is greater in an outer skin region than in a region contained by the outer skin. The foamed thermoplastic material is formed by the inclusion of a foaming or blowing agent within the plastic material before injection into the mould and the foamed plastics material is held under substantive pressure which is inherently lessened upon release into the mould. The glass fibre reinforcement has an average length of 8 mm and comprises 80 % of the weight of the fibre reinforced plastics material. The quantity of foaming agent is sufficient to reduce the weight of the foamed plastics material to 80 % of that which would be the case if not so foamed.

Abstract: A method for quantitatively analyzing digital images of approximately elliptical body organs, and in particular, echocardiographic images. The invention automatically determines the center-point of an elliptical organ and search region for border discrimination by finding the maximum value produced by a series of circular arc filters applied to the image data. The positions of the organ border (10, 11, 12, 13) are then approximated by generating histograms along each of a number of circular segments (1, 2, 3, 4, 5, 6, 7, 8) based on the center-point. The approximated borders are then compared on a best-fit basis to a set of paired elliptical arcs used to model the borders. The image may then be displayed with the modeled border superimposed on the image. A flattened interventricular septum and signal loss across the septum are also determined for echocardiographic images. Cross-correlation is used on histograms generated for selected sectors of image data frames taken at different times to detect organ wall motion in each of the different sectors.

Abstract: A method for enzyme immunoassay for a ligand suspected to be present in a liquid sample includes signal amplification by use of at least two enzymes and a blocked modulator for one of the enzymes. Ligand present in the liquid binds to an antiligand and an enzyme-labeled tracer. The resulting bound fraction is separated and the enzyme in the tracer removes the blocking group from the blocked modulator. The modulator activates or inhibits a second enzyme which catalyzes the conversion of a substrate to a product. The presence or absence of the ligand in the liquid is indicated by a signal, such as a color change or a rate of color change, associated with the product. The invention includes a new class of enzyme inhibitors and blocked inhibitors and a kit of materials useful for performing the method of the invention.

Abstract: A novel rate responsive pacemaker using isovolumic contraction time (IVCT) as a control signal responsive to metabolic demands is disclosed. This control signal is injected into the timing circuit of a standard rate adaptive pacemaker to enhance the pacer's ability to respond in direct relation to the patient's changing metabolic needs as he performs his daily activities. A typical configuration using either right or left heart IVCT for rate control is described, in which the pacing rate is determined by the duration of IVCT. Since pacing rate and IVCT are linearly related, a simple conversion factor can be used to transform the duration of IVCT into the duration of the pacemaker escape interval (pacing rate). Although both right and left heart IVCT could be used for rate control, for the sake of simplicity only the right heart parameters are described herein. The device is capable of operating in most of the available modes (VVIR, DDDR, DDIR, AAIR), and has provisions for multiprogrammability, data storage, bidirectional telemetry, among other standard functions. The device has two inputs to measure IVCT: one, signaling the onset of mechanical activation of the ventricle (start of IVCT), and another, signaling the onset of ejection (end of IVCT). The time interval between these two signals is the duration of IVCT, which is processed by the pacemaker to determine the escape interval, through a simple conversion algorithm, analogous to what is available in the prior art. Onset and end points of IVCT are detected by any combination of biological sensors in the form of pressure, volume or flow transducers. <IMAGE>
