Patent EP-0032040-A1 (EP)
Inventor: DARLING STEPHEN D
IPC: G09B23/26
Filed: 1980-12-22
Abstract: Molecular model building members for the formation of models of molecules and compounds primarily in the field of organic chemistry. Model building members (10, 60) are dimensionally accurate, can be interconnected and/or interlocked, when they are rotatable about their axes, and can thus be used to form specific molecular models. Model building members depicting a double molecular bond (80) and a triple molecular bond (90) can be interconnected and/or interlocked with the model building members (10, 60). All of the aforementioned model building members (10,60,80 and 90) are formed from a polypropylene copolymer material resulting in the members being inherently flexible while retaining sufficient rigidity to depict strain in molecular bonding. Because of this flexibility, the rotatability of the members, and the manner in which the members can be interconnected and/or interlocked, models of all known molecules and compounds in the field of organic chemistry can be formed.

Abstract: Die Erfindung richtet sich auf einen Zahnbesatz für Walzen und Tragsegmente von Textilmaschinen, wie Kämm-Maschinen, Verzugs- und Auflösewalzen für Offenend-Vorrichtungen u. dgl., wie sie zum Kämmen bzw. Auflösen von Woll-, Baumwoll- oder Kunstfaser dienen. Der Erfindung liegt die Aufgabe zugrunde, die Gebrauchseigenschaften und Kosten bekannter Vorrichtungen zu verbessern. Dieses Ziel wird dadurch erreicht, daß parallel nebeneinander angeordnete, je eine auf einem der Befestigung dienenden Fuß angeordnete Zahnreihe aufweisende Elemente vorgesehen sind, wobei die Elemente aus am Außenumfang kreisbogenförmigen Zahnsegmenten (1) bestehen, die eine radial innenseitige Auflagerfläche (5) gegenüber der Lagerfläche der Walze (13) bzw. des Tragsegments (14) sowie mindestens eine axial verlaufende Ausnehmung (2, 6, 7) zur Aufnahme eines achsparallel durch die nebeneinander angeordneten Zahnsegmente (1) verlaufenden und diese verbindenden Haltestabs aufweisen, der an der Walze (13) bzw. dem Tragsegment (14) befestigt ist. Durch diese Maßnahme wird eine besonders leichte Auswechselbarkeit des Zahnbesatzes erreicht, und die Standzeiten werden merklich erhöht, da der Sägezahndraht durchgehärtet werden kann.

Abstract: A device (10) for holding a slider (11) in position for threading onto a slide fastener chain (12) includes a housing (17A, 17B) having a support surface (19A, 19B) for supporting thereon a slider body (13) upside down, and a slit (23) receptive of a pull tab (15) hanging from the slider body (13). A lever (25) has a pair of juxtaposed first and second arms (29, 30) disposed one on each side of the slit (25), there being on the first arm (29) a locking projection (32) movable into and out of the slit (23). The lever (25) is pivotable in the housing (17A, 17B) between a slider-holding position and a slider-release position. The second arm (30) extends beyond the first arm (29) to such an extent that as the slider (11) is placed on the support surface (19A, 19B), the second arm (30) is pressed downwardly by a yoke (14) of the slider (11) to cause the lever (25) to be pivotally moved to the slider-holding position. When a pull is exerted on the slider (11) during the threading of the fastener chain (12) through the slider (11), the second arm (30) is brought into contact with the slider body (13), thus preventing the lever (25) from being pivotally moved to the slider-release position.

Abstract: In a radiation image read-out system in which a stimulable phosphor sheet carrying a radiation image stored thereon is exposed to stimulating rays, and light emitted from the phosphor sheet is photoelectrically read out to reproduce a visible image, the gradient of a decay curve of the phosphor sheet is detected by exposing the phosphor sheet to stimulating rays and detecting the light emitted therefrom. Preliminary read-out for reading out image input information stored on the phosphor sheet is then conducted by using stimulating rays having stimulation energy lower than stimulation energy of stimulating rays used in final read-out. On the basis of the decay curve gradient and the image input information, read-out conditions in the final read-out and image processing conditions are set. The final read-out is conducted within one hour after the phosphor sheet is exposed to the stimulating rays for detecting the decay curve gradient.

Abstract: Method and apparatus for keeping constant the heat load on gas-fired equipment connected to a gas distribution grid which supplies a gas of variable composition. The pressure of the gas supplied is controlled in such a way, that the square root of the pressure difference between the ambient air and the gas, multiplied by the Wobbe-index of the gas supplied, has a constant value. The Wobbe-index is determined by burning a volume-controlled sample flow of the gas with a volume-controlled excess flow of combustion air and measuring the oxygen content of the combustion gases. This oxygen content has a linear correlation to the Wobbe-index if the fuel gas consists mainly of lower hydrocarbons, as is the case with natural gas. Also, the density of the gas supplied is measured and from the density and the oxygen content measured both the Wobbe-index W as well as the gross colorific value H of the gas are calculated. From the momentary values of H and the gas volume consumed the consumption of heat energy by the gas-fired equipment can be determined, e.g. as a basis for financial settlement.
