Abstract: The invention concerns a system to detect irregularities in the geometry of railway wheels. The system is characterized in that a linearly expanding accelerometer is solidly joined to the rail underneath its head. The accelerometer sensitivity is constant over its entire length and generates a voltage proportional to the acceleration of the rail. For different damages, the rail acceleration takes place in different directions, whereby the voltage amplitude, depending on the type of damage, evinces opposite polarities. Frequency filtering or frequency analysis permit the determination of further criteria which, together with other weighted criteria, are used to characterize wheel damage.

Abstract: For water-treatment in swimming pools, cooling towers, hot tubs, and other systems, it is desired to feed various chemicals in small quantities but at optimum rates into the system. In several embodiments of the invention the water is recirculated through the system which usually includes a filter. It has been discovered that the chemicals can be fed by enclosing them in generally spherical plastic capsules suggestive of table tennis balls, but about the size of a base ball. The rate of feeding depends upon the size and number of small holes which are provided, or the user pokes through the shell of the capsule, upon the solubility of the chemical, and upon the flow rate of the water through a strainer, skimmer, or other chamber in the system into which the capsule is introduced. The random orientation of the capsule tends to average out variations.

Abstract: The invention concerns an apparatus for growing cell cultures wherein the cultures are located in at least one liquid nutrient medium and the nutrient medium or media are introduced through at least one pump-driven feed line, and where a gas (oxygen, nitrogen, air or the like) is introduced into the head room above the liquid level of the closed container, the gas pressure being kept constant in the head room, this apparatus being designed in such a manner as to prevent effectively injury to the free cells perforce ejected when evacuating the nutrient media. To that end the invention provides an overflow line communicating with the liquid in the container and terminating outside this container, its free end being located so much above the liquid level in the container that the pressure generated by the liquid column in the overflow line balances the gas pressure in the container head room.

Abstract: A formed or molded body, a manufacturing method and a manufacturing apparatus therefor, wherein several equal or different active ingredients in suitable, equal or different carrier substances are filled at the same time side-by-side without a partition into a uniform enclosure or envelope to provide a formed or molded body with uniform outer appearance and with separate inner regions.

Abstract: The invention relates to a heat-curable binder mixture which comprises an organic synthetic resin A and a crosslinking agent B. Said synthetic resin A can be an epoxy resin, a polyester resin or an acrylate resin having a number average molecular weight of 500 to 20,000 and at least 0.2 equivalent per 100 g of resin of primary and/or secondary amino groups and/or hydroxyl groups, and said crosslinking agent B is an organic compound having at least 2 .beta.-alkoxyalkyl ester groups per molecule.

Abstract: Interferon is produced in-vitro from whole blood, obtainable from animals or humans including blood from corpses or retroplacental blood, in a simplified non-critical process preferably carried out in a sterile system of interconnected plastic bags. The blood is stabilized and innoculated with an interferon inducer before culturing in an incubator. This results in interferon containing blood useful directly for transfusions or further processable to obtain a variety of therapeutic interferon containing preparations including plasma, serum and albumin in accordance with disclosed phases of this invention. Interferon carrying plasma is thus separated and treated further to isolate interferon carrying serum or albumin, if desired. In-vivo innoculation to produce antibodies before taking blood provides improved disease fighting characteristics in the derived product.

Abstract: A lighted automobile vanity mirror for mounting on an automobile sun visor has a switch for operating the illumination only when the vanity mirror is in the vertical position. This switch is a ball contact switch which rolls from an inoperative horizontal position of the vanity mirror to an operative vertical position where gravity draws the ball switch into contact with the circuits.

Abstract: A shower system comprising an elongated tubular conduit having several windings arranged in helix formation with a central helix axis disposed vertically is used by persons to shower. Perforations having an outlet size of about 0.8 mm.sup.2 are located in the inner sidewalls of the windings which sides face toward the central helix axis. A length of the spraying extends over a length of about 10 to 20 meters so that the internal helix space houses a person standing or sitting therein. The temperature of the water ejected from the perforations can be raised so high and can be sustained for so long that the person taking such a shower undergoes a sauna effect. This sauna effect is provided by a distance between adjacent perforations, in the spraying zone, of about 2.5 to 10 centimeters (or 200 to 400 over the entire spraying zone).

Abstract: N-methylmorpholine-N-oxide is prepared by reacting the azeotrope of methylmorpholine and water with an aqueous solution of hydrogen peroxide. The reaction solution product is thereupon concentrated to the desired content in N-methylmorpholine-N-oxide.

Abstract: The invention concerns an assembly of sets of tightly adjacent eye needles (12) for filling-yarn knitting machinery. One set each of eye needles (12) is anchored by injection-molding in supports (8,9) at mutually equidistant positions, the needles being mutually parallel by their main planes. Two supports (8,9) each with a set of eye needles (12) form one segment of eye needles. The heads (22) of the eye needles (12) of the first set (24) of needles alternatingly enter centrally between every two heads of the eye needles of the second set (25) of needles. The two sets of needles are fixed within the segments and are oblique in such a manner that a conceptual plane from one of the sets (24) of needles (plane (5) of the set) extending along the eye needles and through the heads of this set of needles intersects the plane (5') of the set of the other needle-set (25) in the region of the heads.
