Title: Packaging container, method of making it and device implementing the method
Inventor: MATSUI TAKASHI
IPC: B65D77/20
Filed: 1976-06-30
Abstract: The packaging container, for example intended to receive eggs, comprises a lower element (1) of rectangular shape in which appropriate housings are formed and which is made from a sheet of expanded plastic material, and a corresponding upper element (101) made from a sheet of non-expanded plastic material. The respective upper and lower elements comprise peripheral rims. The rims have, along the long sides, portions which, after insertion of the products or articles to be packaged, are heat sealed and folded downwards, the ends of these portions however being left unsealed in order to constitute a means of grasping for the purpose of the subsequent opening of the packaging container. This container has good solidity and can be opened easily. <IMAGE>

Patent CH-573872-A5 (CH)
Title: Sterilisation of fluids and gases by ultraviolet radiation - UV-ray-permeable flow tubes in a ring, assembled integrally with lamps
IPC: A61L2/10
Filed: 1974-12-20
Abstract: The parent patent described a device for destroying bacteria in fluids and gases by means of ultraviolet radiation tubes and a tubular vessel, permeable by ultraviolet rays, the radiation lamps being located on parallel axes around it; through which the fluid or gas to be sterilised flows. In the patent of addtn, the circulation system consists of a number of similar flow tubes arranged in a circle, with ultraviolet radiation lamps positioned axially parallel to their inner and outer surfaces. The flow tubes are clamped between two similar end covers which also have provision for the correct positioning of the radiation lamps. The end covers have a ring channel, rectangular in section for the fluid to and from the flow tubes and a flange with recesses for the outer lamp holders and a two-piece reflector, as well as a central bore for a bearing with at least one lamp. More intimate assembly of the radiators and the flow tubes intensifies the action so as to increase throughput, whilst the use of numbers of similar components cheapens production.

IPC: B61F3/12
Filed: 1987-10-02
Abstract: Die Erfindung betrifft ein mehrgliedriges Schienenfahrzeug fuer den Nahverkehr. Bei einem solchen Fahrzeug ist es wuenschenswert die Einstiege nur geringfuegig ueber dem Strassenniveau zu haben und das ganze Fahrzeug ohne Stufen durchschreiten zu koennen. Zu diesem Zweck wird erfindungsgemaess ein niveaugleicher durchlaufender Mittelgang vorgesehen, der sich auf gleicher Hoehe wie die Einstiege befindet. Um die Triebdrehgestelle unterzubringen, erfolgt der Antrieb der Radsaetze ueber Gelenkwellen und Untersetzungsgetriebe. Die Fahrmotoren koennen dabei seitlich unter dem Wagenkasten ausserhalb des Schwenkbereiches des Triebdrehgestelles angeordnet sein. Falls es der Raum zulaesst, koennen auch Vertikalmotoren in einem der Ecken des Wagenkastens angeordnet sein, die ueber Gelenkwellen und Untersetzungsgetriebe die Radsaetze antreiben. Vorteilhaft ist die Anordnung zweier zum Drehpunkt des Triebdrehgestelles diagonal liegender Fahrmotoren, deren Antriebswellen parallel zu den Radsaetzen angeordnet sind, wobei das Drehmoment mit Gelenkwellen uebertragen wird. Die Quertraeger des Triebdrehgestelles sind zur Aufnahme des Mittelganges abgekroepft. Durch die Anordnung der Einstiege und den auf gleichem Niveau durchlaufenden Mittelgang wird der Fahrgastwechsel beschleunigt, die Haltezeiten reduziert und kostenaufwendige fussbodengleiche Bahnsteige ueberfluessig.
