Patent CH-571928-A5 (CH)
Title: Reducing friction during the machining of metals - using jet of air mixed with gas such as fluoro-chloro-hydrocarbon
IPC: B23Q11/10
Filed: 1974-06-10
Abstract: Process for reducing friction between the tool and the workpiece in metal working operations, the novelty being that a gas mixt. which reacts with the metal surface is supplied during the operation. The process is pref. used in chip-forming machining operations, where the gas mixt. is fed to the cutting zone for both reducing the friction and cooling. The gas mixt. pref. contains chlorine, phosphorus or sulphur and/or is able to form chemical reaction products with liqs. The resulting product is clean and free from oil and can be used e.g. to make adhesive joints without any prior treatment such as oil removal.
Patent CH-574799-A5 (CH)
Title: Yarn cutting and clamping mechanism - has moving cutting blade coordinated with clamps to hold cut yarn end
IPC: B65H54/71
Filed: 1974-07-17
Abstract: The yarn clamping and cutting system, for use with a texturising process, incorporates a blade beld by at least one spring against a counter blade and pivoted to a slide. The moving blade works in conjunction with the stationary counter blade, the cutting edge of the moving blade being slanted, while the fixed counter blade is L-shaped. The clamping action is effected by a clamping spring acting on two opposing components, the yarn guide being moved to the side by a moving section of the clamp in the form of two sets. The moving section of the clamp is arranged with the slide and the moving blade to compensate for the tolerances experienced when working with yarns of varied dies. The moving blade and its spring are made of spring steel, and can be formed as a single integrated component. Similarly the clamping spring and the moving section can be formed as a single unit. The system ensures that the yarn is cut cleanly, and that the cut yarn end is secured and held to be extracted by hand.

Patent CH-582864-A5 (CH)
Title: Heat exchanger with flexible plastic transfer surfaces - incorporating treatment on liq. side improving wetting, maximising transfer coefficient
IPC: F28D3/00
Filed: 1974-09-17
Abstract: The parent patent described a heat exchanger in which a horizontal pipe carrying a liq. is placed between the surfaces of a shell. These surfaces are sheets of flexible plastic and are suspended from the horizontal pipe. The pipe has two perforations allowing liq. to flow from it on to the sheets, and there is an outlet at the bottom of the shell, with a liq. seal. There are means of ereating a flow of gas along the outer surfaces of the shell. The improvement consists of treating the surfaces down which the liq. flows to improve the overall heat-transfer coefficient. The treatment gives the surfaces a critical superficial tension equal to or greater than the surface tension of the liq. in the same temp. range. The treatment is either to make the shell of cellulose acerate, or pref. to make it of ethylene polyterephthalate and to coat the internal surfaces with acrylic acid fired by radiochemical means.

Title: Preventing water flow from mine passages
IPC: F42D1/24
Filed: 1970-07-06
Granted: 1972-03-03
Abstract: A particulate solid material is deposited in the passage to form an initially water-permeable plug. The material reacts with the water to form an insoluble ppte which progressively reduces and eventually prevents flow of water through the plug. The material may be limestone or dolomite which will react with and neutralise acidic water contg. iron acids and sulphates to ppt. iron oxidies, hydrated ferric sulphate and calcium sulphate. The acidic water is thus prevented from flowing into and polluting streams and rivers.

Title: Messgeraet und messverfahren zur entfernungsmessung mittels polarisationsmodulation
Inventor: FROOME KEITH D
IPC: G01S7/48
Filed: 1987-01-06
Abstract: Bei einem Entfernungsmesssystem wird polarisiertes Licht von einer Haupteinheit (8) zu einem Zielreflektor (46) projiziert und wieder reflektiert. Die Polarisation wird moduliert durch einen elektrooptischen Pockelsschen Kristall (20), der im Strahlenweg des projizierten und zurueckgeworfenen Lichts angeordnet ist, wobei ein variabler Lichtweg (42, 44) so justiert wird, dass am Photodetektor (50) nach dem Durchgang des zurueckgeworfenen Lichts durch ein Polarisationsfilter (18) ein Nullwert ermittelt wird. Damit ein einziges Filter (18) fuer die Polarisierung des projizierten Strahlenbuendels und zur Filterung des zurueckgeworfenen Strahlenbuendels ausreicht, kann eine relative Phasenverzoegerung von etwa einem Viertel Wellenlaenge durch einen Rhombus (38) in das projizierte und zurueckgeworfene Strahlenbuendel eingefuehrt werden. Damit die sonst erforderliche Ausrichtung des Filters (18) mit den Achsen der quer zum Strahlenbuendel verlaufenden Kristallachsen umgangen werden kann, ist der Rhombus vor dem Kristall (20) in dem projizierten Strahlenbuendel anzubringen, so dass der Kristall im allgemeinen zirkular polarisiertes Licht empfaengt. Zur Regulierung der Qualitaet des am Photodetektor erzielbaren Nullwertes, kann die Ausrichtung des Rhombus nachreguliert werden. Damit der Nullwert mit groesserer Genauigkeit nachweisbar ist, koennen entweder die Modulationswellenlaenge, die Laenge des Lichtwegs oder die Zeitverzoegerung des Lichtwegs gewobbelt werden. Um Messwerte fuer eine Struktur zu entnehmen, die hinsichtlich einer Bezugstemperatur korrigiert sind, kann die Modulationswellenlaenge fuer einen Bezugsresonator (72), der aus demselben Material wie die Struktur besteht und in Beruehrung mit dem Kristall angeordnet ist, festgelegt werden.
