Abstract: A B S T R A C T     A plastic profiled sealing element for household refrigeration appliances, such as freezers, refrigerators, freezer chests, freezer compartments etc., includes a sealing bellows having a hose-shaped cross section.  The sealing bellows is provided with two side walls and a covering wall and is made of a plastic which has been set by means of a softener so as to be continuously flexible.  Further, the profiled sealing element is provided with an anchor member made of a plastic of the same or different material hardness, with the sealing bellows and the anchor member being connected with one another to form a unit.  The cross sections of the two side walls of the sealing bellows narrow as the side walls rise from the region of the connection of the side walls with the covering wall of the anchor member to approxi-mately half the height of the sealing bellows, so that the side walls become increasingly thinner.  Thereafter, the cross sections of the side walls increase again to the edges of the covering wall of the sealing bellows, until the side walls again reach approximately their initial cross sections.          The side walls, on the one hand, and the covering wall, on the other hand, are kept flexible by means of softeners having different characteristics.

Abstract: ABSTRACT OF THE DISCLOSURE      Methods and compositions are provided for performing an assay on whole blood samples.  The method is for a determination of an analyte which is a member of a specific binding pair (sbp) consisting of ligand and homologous receptor.  The method involves a binding agent for the red blood cells in such sample, a solid bibulous element to which is bound at least one sbp member, and a signal-producing system.  The method comprises combining the whole blood sample, the binding agent, and none or, where appropriate, one or more members of the signal producing system.  The medium is next contacted with a portion of a solid bibulous element to which is bound one of the members of the specific binding pair to allow the medium to traverse such element (immunochromatography). The solid bibulous element is contacted with any remaining members of the signal producing system.  Signal resulting from the signal producing system is detected and is related to the amount of the analyte in the sample.

Abstract: ABSTRACT                 TRANSITION  BETWEEN   A   CONTINUOUS AND  A CORRUGATED CIRCULAR WAVEGUIDES FOR  EFFICIENT   LAUNCH    OF SIGNALS IN TWO FREQUENCY BANDS.                 The invention relates to a transition   for propagating signals between a continuous and  a   corrugated circular waveguides with minimized and low   spurious   mode excitations in two bands of frequency. The transition     a-chieves transformation of the TEll mode, the dominant signal carrier mode of a continous waveguide, into the HEll  hybrid mode, the corresponding mode carrying signals in the  corru-gated structures, by employing a tapered waveguide   transi-tion of circular cross-section having dual-depth circumfer-encial corrugations in the interior boundary surface.    The transition utilizes mutual resonance property of  dual-depth corrugations at the port which connects to continuous  wave-guide to achieve a satisfactory return loss in two bands. At the port which is connected to the corrugated horn,  whereas the quarter wavelength self-resonance of the individual slots in the dual depth corrugation configuration provides the de-sired HEll hybrid mode under balanced hybrid condition    in two bands. A gradual transition of the electrical character-istics is achieved along the length of the transition through an adjustment of the corrugation parameters. Excitation   of higher order spurious modes can be maintained at a low level when properly chosen cross-sectional dimensions are consid-ered along the length of the transition.

Abstract: ASTRACT OF THE DISCLOSURE        The radial dimension of selected teeth in toothed wheels used for measuring the transmitted shaft torque are changed in a predetermined spatial pattern corresponding to desired information.  Such embedded data structures within the torque measurement apparatus may be used for encoding data uniquely related to the shaft twist modulus of a particular torque meter.  In this manner, the toothed torque and/or reference wheels may be used to self-compensate or program? appropriate electronic signal processing apparatus, so as to automatically take the particular shaft twist modulus fully into account before producing output torque measurement data.          At the same time, the use of such different radial tooth dimensions provides a differential amplitude modulation component in the sensor output signal which may be used to sense the relative gap dimensions (i.e., between rotating toothed wheels and a variable reluctance sensor), such that this variable parameter can also be taken fully into account by the signal processing electronics before a final output torque measurement signal is produced.  Compensation for shaft speed and sensor temperature variations may also be achieved so as to result in final measured torque output data automatically compensated for variations in shaft modulus, gap, speed and temperature.

Abstract: METHOD AND APPARATUS FOR REMOVING CATARACTOUS        LENS TISSUE BY LASER RADIATION           ABSTRACT OF THE DISCLOSURE    The invention contemplates apparatus and technique for surgically non-invasive surgery to remove cataracted-lens tissue, enabling the beam output of a laser to be focused from a convergent-ray bundle to a focal spot of maximum power density at the anterior surface of a cataracted lens and which scans the focal spot over a predetermined area or areas of the cataracted lens.  The beam is a focal and therefore diffuse as it enters the eye through the cornea, and it is also diffuse (being divergent) in the controllably unlikely event that the laser energy passes through an opening it has created in the cataracted lens; the diffusion assures against damage to either or both of the cornea and the retina, for power levels sufficient to achieve ablative photodecomposition and/or thermal decomposi-tion and/or photofragmentation and/or photoemulsifica-tion of the cataracted-lens tissue.  Various features are disclosed for assuring safety and uniformity in the removal of involved tissue.

Abstract: HEAT TRANSFER DEVICE, FOR THE TRANSPORT OF LARGE   CONDUCTION FLUX WITHOUT NET MASS TRANSFER           ABSTRACT OF THE DISCLOSURE         A device for the transport of large conduction heat flux between two locations of differing temperature includes a pair of fluid reservoirs for positioning at the respective locations connected by at least one duct, and preferably a plurality of ducts, having walls of a material which conducts heat.  A heat transfer fluid, preferably a liquid, and preferably a liquid metal such as mercury, lithium or sodium, fills both reservoirs and the connecting ducts.  An oscillatory axial movement or flow of working fluid is established within the ducts, with the extent of fluid movement being less than the duct length.  Preferably the oscillatory movement is sinusoidal.  Heat is transferred radially between the fluid and the duct walls and thence axially along the ducts.  The rate of heat transfer is greatly enhanced by a physical mechanism which may be described as a high time-dependent radial temperature gradient produced by fluid oscillations.  During most of each sinusoidal cycle, fluid in the wall-near region has a temperature different from the core of the fluid column, with most of the temperature difference concentrated across a relatively thin boundary layer.
