Abstract: The present invention relates to novel ethane derivatives of the formula 1 <IMAGE>  in which R<a> is straight-chain alkyl having 1 to 8 carbon atoms, <IMAGE> or (m = 1 or 2; n = 0 or 1) and R<b> is straight-chain alkyl having 1 to 8 carbon atoms in which, in addition, one or two non-adjacent and in each case non-terminal CH2 group(s) may be replaced by -O-, and to the preparation of the compounds of the formula 1, to liquid-crystalline phases containing compounds of the formula 1, and to their use as components of liquid-crystalline phases. The compounds of the formula 1 have high chemical stability and only low conductivity. They are colourless and readily miscible with all common liquid crystals. Their use in liquid-crystalline phases results in broader mesophase ranges and reduced viscosity. The compounds of the formula 1 according to the invention are thus highly suitable for liquid-crystalline phases for electrooptical display devices, such as, for example, TN cells or guest-host cells.

Abstract: A method for forming a sheet material adapted to be cut into smaller pieces to form portions of a fastener. The method comprises providing a backing laminate comprising a layer of base material and a sealing layer of heat softenable polymeric material along a back surface of the base material; stitching a plurality of yarns through the base material to form loops projecting from a face surface of the base material and locking portions of the stitch adjacent the back face of the base material; and heating the polymeric material to adhere it to the locking portions of the stitches. The sheet material can then be used if loops are desired, or the loops can be cut to form hooks or heated to form headed projections on the sheet material.

Abstract: A method and apparatus are disclosed for measuring the aggregation of blood platelets or the coagulation of blood, the apparatus including a capillary tube for drawing blood, a piston in communication with the capillary tube and connected to a motor means for linear displacement thereof, a pressure sensor in the space located between the drawn blood and piston, and a computing means or microprocessing means for comparing the sensed pressure from the pressure sensor with a predetermined value, and providing a measured regulating output to the motor means. The method for measuring the aggregation of blood platelets and coagulation of blood includes the steps of drawing blood into the capillary tube of the moveable piston until the desired pressure is achieved within the capillary tube, and allowing the computing means to then maintain by adjustment of the piston position the pressure within the capillary tube. The computing means is able to determine the amount of blood flowing into the capillary tube during constant pressure regulation, and hence the amount of aggregate of blood platelets and blood coagulation due to a known relationship relating movement of the piston to blood drawn into the cylinder.

Abstract: This invention relates to formaldehyde-free, aqueous glue dispersions which contain polyisocyanates. These systems are particularly suitable for gluing veneers and surface materials on wood and wood products. The systems are prepared from polyisocyanates in combination with extenders based on flours and cold water-soluble of hydrolyzed natural starch. In this process, polyisocyanates or aqueous dispersions thereof are added while stirring to aqueous solutions or mixtures of starch and flour. The extender-containing adhesive systems are aqueous glue dispersions having increased service life which in their preferred embodiment contain about 15 to 30% by weight of polyisocyanates, preferably polyphenyl-polymethylene polyisocyanate (PMDI), 10 to 15% by weight of starch which is soluble in cold water and 14 to 25% by weight of (cereal) flour and optionally, other additives and the appropriate quantity of water adding up to 100% by weight. The glue dispersions are easily applied with glue spreading machines and if applied in suitable quantities do not bleed through veneers. The implements used for applying the glues can easily be cleaned by rinsing them with water. The invention is also directed to the use of the glue dispersions for gluing, particularly for gluing veneers or other surface coating materials to wood or wood products.

Abstract: An envelope having flexible water-permeable walls contains one or more water-disintegratable, self-coherent compresses of hydrogel particles. On contact with water, particularly in the stomach, the compresses first disintegrate and then the hydrogel particles swell to cause inflation of the envelope. The envelope is thereby inflated and retained in the stomach. The envelope is particularly useful as a device for the sustained release of active ingredient whereby the envelope contains biologically, veterinarily or pharmaceutically active ingredient in sustainedly releasable form. The use of the compressed hydrogel enables large amounts of active ingredient and/or hydrogel to be included in the envelope while still having an envelope sufficiently small to be swallowed by the patient or forced down the throat of an animal.

Abstract: A pharmaceutical composition for topical administration consisting of two liquid phases designed to be admixed in situ or prior to use. The first phase contains a dissolved drug, and is preferably saturated in the drug, whilst the second phase is a chemically or physically different liquid from that in the first phase and contains no drug, but is miscible with the first phase. The two liquids are selected so that, on admixture of suitable volumes of the phases, the resultant drug concentration exceeds the saturated drug solubility in the resultant mixture. This produces a liquid mixture supersaturated in drug, which has been found to increase the rate of drug penetration into the skin. The two liquid phases may be gels, and the drug may be hydrocortisone. At least one phase contains an antinucleant to improve stability of the resulting supersaturated solution.

Abstract: A disposable, sterilizable cable drive unit for an intravascular blood pump includes a rotor enclosed in a fluid-tight enclosure which can be slipped into the stator of a drive motor. The unit is connectable to a constant-rate purge fluid supply and to a dual-lumen cable sheath. One lumen provides a sterile purge fluid path; the other carries the drive cable to the blood pump and provides a return path for a flushing fluid in which the cable is immersed. The flushing unit is derived from the purge fluid supply at a constant rate, and the rotor may also be immersed in it if desired. The unit is held in the drive motor by a manually operated detent, and the self-centering action of the rotor aligns it with the stator when the motor is energized. The motor is mounted on a gimbal so as to be alignable with the cable sheath at its point of insertion into the patient's vascular system, in order to prevent stresses on the patient and kinks in the cable sheath.
