Abstract: The invention relates to the use of a reactive liquid applied material for producing a roofing membrane, wherein the reactive liquid applied material has a liquid component and a powder component, wherein the powder component comprises a mineral binder system consisting of a plurality of mineral binders capable of forming an ettringite phase when combined, and wherein the liquid component comprises one or more aqueous polymer dispersions. According to the invention, the reactive material contains at least twice, preferably at least 2.5 times, in particular at least three times as much wt. % solids content of polymers as it does wt. % mineral binders, a proportion of a PU polymer is at most 30% of the solids content of polymers, relative to the total mass of the polymers, and at least one of the polymers used in the reactive roof waterproofing product has a Tg determined by DSC of less than ?20° C., preferably less than ?30° C.

Abstract: A syringe for connection to a fluid container containing fluid to be discharged comprises a syringe barrel with a plunger moving therein, and a discharge outlet, through which fluid contained in the fluid container is dischargeable by actuation of the plunger, said syringe barrel being connected with the fluid container port and the discharge outlet via a fluid channel system, and a valve mechanism being provided in the fluid channel system, allowing the syringe barrel to be filled with fluid from the fluid container and to then discharge said fluid through the discharge outlet, wherein the valve mechanism comprises a valve member which is movable between first and second positions, said valve member, in said first position, allowing fluid flow from the fluid container to the syringe barrel and simultaneously blocking fluid flow from or to the discharge outlet and, in said second position, allowing fluid flow from the syringe barrel to the discharge outlet while simultaneously blocking fluid flow from or to t

Abstract: An endoscope comprising a shaft having distal and proximal ends is provided, which shaft comprises an outer tube in which an inner tube is inserted such that it is rotatable relative to the outer tube and displaceable in the longitudinal direction of the tubes and such that a first channel is formed between the two tubes, with an instrument tube and imaging optics being arranged in the inner tube and a second channel being formed therein, and with both the instrument tube and the imaging optics being connected with the inner tube in a manner locked against rotation relative to each other.

Abstract: An electronic endoscope is provided, comprising a shaft, an image-recording unit, which has an objective as well as, arranged following the objective, an image sensor for recording an object, and which is securely connected to the shaft at the distal end thereof, said endoscope further comprising a handpiece connected to the proximal end of the shaft, as well as an illumination device, connected to the shaft, for illuminating the object to be recorded, wherein the illumination device comprises at least one light emitting diode.
