Abstract: The electrical turn/pull switch for vehicle lighting has an operating part (14) that is mounted in a switch housing (12) so as to be rotatable as well as axially movable. The movable contact elements (22, 24, 26) of a contact carrier (20) interact with fixed contact elements (30). The contact elements for the turn switch function (22) and for the axial switch function (24, 26) are integrated on the contact carrier (20). An actuation part (16) entrained by the operating part (14) has cams and/or ramps (18) that engage the movable contact elements (24, 26) and actuate them.

Abstract: A method for processing an olefin-containing product stream that contains dimethyl ether as a by-product is described. Such a product stream arises, for example, in the synthesis of olefin from methanol. For separation of the dimethyl ether from the product stream, it is proposed that at least a partial stream chiefly containing C3 hydrocarbons is separated from the product stream by fractionation, and is sent to a rectification column (C3 splitter) (16) for separation of propylene and propane. The dimethyl ether goes together with the propane into the bottom of the rectification column in the rectification process and can be withdrawn (42). A substantially pure propylene product (41), which contains at most only traces of dimethyl ether, can be removed from the top of the rectification column.

Abstract: Disclosed is a method for producing emulsifiable protein products from the plant seeds of an oilseed crop, in particular soybeans, in which the plant seeds are comminuted and undergo a de-oiling step and supercritical CO2 is added to the comminuted plant seeds as a solvent, and crude oil and a de-oiled residue containing the emulsifiable protein products are obtained by means of separation.

Abstract: A frontal part comprising a decorative part made from a support, from a decorative layer applied thereto, and from a heat-cured layer situated on the decorative layer, and also, if desired, comprising a reinforcer for supporting the decorative part. The frontal part may also comprise an intermediate layer between the support and the decorative layer. The support and the reinforcer may each be composed of a thermoplastic, for example of polypropylene or of polyethylene.

Abstract: The rotary light switch for motor vehicles has a housing (10) and an actuating member (14) mounted rotatably. In a peripheral wall (24) of the housing, a cam surface (26) is recessed, which runs in peripheral direction and rises axially facing axially away from the actuating member. A cam follower (22) projects radially from the actuating member (14) and runs up on the cam surface on rotation of the actuating member, bearing only axially on the cam surface and forcing the actuating member (14) to move axially.

Abstract: An electric switch has a switch housing, a knob mounted in the housing, a guide gate having latching recesses and arranged inside the switch housing, and a spring-loaded cam follower guided by the guide gate. The switching positions of the switch are defined by interaction of the cam follower with the guide gate and with its latching recesses. The guide gate has damping elements made of elastic material and fitted in the latching recesses.

Abstract: The invention relates to a method and to a device for the non-invasive detection or determination, by Raman spectroscopy, of the concentration of substances in body fluids. The aim of the invention is to facilitate a non-invasive in vivo detection of substances in body fluids that allows for very accurate, reproducible results of analysis while requiring only little time for measuring which is acceptable for the patient. To this end, the inventive method and device for carrying out a Raman spectroscopy of a body fluid in a body tissue (1) records at least two Raman spectrums under different physical conditions and compares them with each other. The result of comparison allows detection of the substance one is looking for and measurement of the concentration of said substance.
