Abstract: A protective cover for an optical sight of a firearm, with at least one transparent end wall section for protecting either a proximal opening or a distal opening of the optical sight is disclosed. In order to provide a backup sight, it is proposed for the transparent end wall section to have a permanently displayed optical reticle or a part of this reticle.

Abstract: An optical sight for a firearm can be provided with multiple light sources for illuminating one or more aiming marks on the sight. The light sources may be multiple LEDs, e.g. of different colors that can provide illumination in different lighting conditions. The lights sources may also be physical process driven light sources, such as a Gaseous Tritium Light Source (GTLS). A combination of LEDs and GTLS may also be used. The light sources may be disposed at multiple focal points of a multi-lens system. Alternatively, a selector may be used to selectively locate one of the light sources at the focal point of a single lens system. The optical sight may be a reflex sight, e.g. for a handgun, or may be a riflescope for a rifle.

Abstract: The present invention relates to a rodent H-1 parvovirus variant capable of propagating and spreading through human tumor cells. In particular, the present invention relates to a parvovirus variant (H-1PV DR) that is based on wild-type H-1 PV but contains a 114-nucleotide internal deletion and a 55-nucleotide repeated motif towards the right-end terminus in the presence of full length of right-end ITRs. This variant displays improved anticancer activity. The present invention also relates to a pharmaceutical composition containing such a parvovirus variant as well as its use for the treatment of cancer.

Abstract: A lighting element for a firearm or sight with a gaseous tritium light source and with an injection-molded plastic housing, wherein the plastic housing at least partially encloses the gaseous tritium light source. High mechanical ruggedness can be achieved if the plastic housing at least partially consists of a polyamide 12 (PA12)-based or polycarbonate (PC)-based plastic.

Abstract: A safety selector assembly for retrofitting a manual firearm safety of a firearm and a safety selector lever for the manual firearm safety. So that the safety and/or fire mode of the firearm can be clearly read, the invention proposes for the opacity of the head section to be interrupted by at least one see-through region between the front side and back side positioned eccentrically to the rotation axis in order to thus enable visibility of at least one safety marking of the manual firearm safety.

Abstract: A gaseous tritium light source (GTLS), which has a hermetically sealed outer sleeve made of glass, more particularly borosilicate glass. A high durability and lighting intensity is produced due to the fact that at least some sections of the outer sleeve have an outer coating applied directly to the outer surface of the outer sleeve serving as a reflective layer made of a metal, wherein the outer coating has an epitaxial structure and wherein the metal has a reflectance of >70% for visible light.

Abstract: A lighting element with a gaseous tritium light source and an elongated plastic housing that at least partially encloses the gaseous tritium light source with its housing shell and forms a latching element that snaps together with the gaseous tritium light source, which can be inserted into the plastic housing, and holds it in the plastic housing. A rugged lighting element can be produced if the latching element is formed by at least one catch element, which catch element has a radially sprung flexible spring and at least one, preferably two, inwardly oriented snaps with an indentation for snapping together with the gaseous tritium light source.

Abstract: A folding knife and related method include actuating elements for locking or unlocking the blade of the knife. The actuating elements are permanently illuminated or backlit so that the actuating elements are more clearly visible in low light conditions and can therefore be safely operated. Such features for knife applications may provide advantages for particular activities where knives are commonly used, such as for law enforcement and hunting.

Abstract: A shock device for an at least partially muscle-powered two-wheeled vehicle, including at least one tube system having two telescopic tubes, the tube system extending from a first end to a second end. A suspension system is provided which is effective between the two ends and which biases the two tubes to an extended position. The suspension system includes a positive air spring and an independent, series-connected supplementary spring. Both the positive air spring and the supplementary spring bias the tube system to the extended position. The supplementary spring shows a lower breakaway force than does the positive air spring, and the ratio of the suspension travel of the positive air spring to the suspension travel of the supplementary spring is higher than 4:1.

Abstract: A shock device for an at least partially muscle-powered two-wheeled vehicle including a damping system having a damper cylinder and a moving piston disposed therein and connected with a piston rod extending from the damper cylinder, wherein the piston acts on a first damping chamber in the damper cylinder in the compression stage as the piston rod plunges in from a retracted base position into a plunged-in position. In the damping system, as the piston rod plunges in, damping fluid is transferred from the first damping chamber to an auxiliary chamber. A flow resistance for transferring the damping fluid into the auxiliary chamber is configured travel-dependent, depending on the piston position. The flow resistance for transferring the damping fluid into the auxiliary chamber over a first travel distance of the piston including the base position is smaller than over a second travel distance that is plunged in further.

An effective flow cross-section for the high-speed throttle is adjustable.

Abstract: A method for detecting an element in a sample using a transmission electron microscope to measure a first image of the intensities of the sample at an energy loss in the range of the element signal. The background at various points is determined in a comparator sample which does not contain the element intensity. Energy loss is determined at the front of the element signal, and an energy loss is determined in the range of the element signal. From these values an approximation function is calculated so that an image of the pure element-specific intensities can be calculated.
