Patent CH-676800-A5 (CH)
Title: Combined gas filter, partic. for air - comprises three elements, first two are perforated and made of tough material which can be folded, and third is made of fibre mesh
Inventor: PROGIN RENE
IPC: B01D50/00
Filed: 1988-05-31
Abstract: The combined filter for gases is made up of three elements.  The first two elements are perforated and are made from a material which is tough but can be folded. These first two elements act as a preliminary filter and also support the final filter. They are folded so that chambers are formed, across which the gas to be filtered flows. This makes it turbulent, so the majority of the particles suspended in the gas stay attached to the sides of the chambers.  The third element which forms the final, fine part of the filter, is a mesh of fibres which has a loose enough texture to allow the gas to pass through but retain the last particles which the preliminary filter has allowed to pass. The first two elements are to protect the third and to support it. The vol. of the filter can be reduced for transport, handling and storage. U/ADVANTA - riC. tOF h filFin O lF VOlS.  of air for e.g. factories. The filter is slow to clog up, simple and efficient. It can also be made smaller for transport, handling and storage.

Patent CH-661801-A5 (CH)
Inventor: CANZEK LUDVIK DR
IPC: G02B25/00
Filed: 1983-09-19
Abstract: A magnifier lens has a focal length f and a distance of at least 0.58f between the exit pupil (EXP) and the last lens (L5) vertex. This magnifier lens comprises, successively from the object-side to the eye-side, a lens, such as a meniscus lens (L1) with its concave side facing the object, a positive lens (L2) and a negative lens (L3) as well as a meniscus lens (L4) and a positive lens (L5), defining the last lens, separated by an air space (d7). The meniscus lens (L4) faces the eye with its concave side. The use of thin lenses permits a short overall length of a preferred embodiment of only 1.27f, and a sum of the lens thicknesses of 0.89f. Three large lenses (L2, L3, L4) may be made of so-called light-weight glass (SKL15 and SFL11) instead of regular glass. This results in a handy magnifier of short length and low weight with low cost of manufacture due to the small number of lens elements. A good state of correction is evidenced by a distortion of under 3 percent for a semi-field angle of 20 DEG . The magnifier lens is particularly well suited for use in optoelectronics, i.e. for observation of the image on the anode screen of an electronic tube.

Der Hydraulikmotor wird ueber ein normalerweise geschlossenes Schaltventil in den Hydraulikkreislauf eingeschaltet. Der Hydraulikmotor ist ueber eine schaltbare Kupplung mit einer Welle des Elevatorfoerderers antriebsverbindbar. Der Hydraulikmotor und die hydraulisch betaetigbare Kupplung sind gleichzeitig mit Druckmittel beaufschlagbar. Der Druckanstieg in der Kupplung ist so gewaehlt, dass der erforderliche Druck zur Betaetigung der Kupplung sich eingestellt hat, bevor der notwendige Antriebsdruck fuer den Hydraulikmotor sich eingestellt hat. Auf diese Weise kann nach Abschaltung des Hauptantriebes der Elevatorfoerderer ohne die Gefahr der Beschaedigung der verschiedenen Antriebselemente in kuerzester Zeit auf Ruecklauf umgestellt werden.
