DISINFECTING AND STERILIZING AGENT BASED ON PERCARBOXYLIC ACID
The invention relates to a composition in solid form, containing a) at least one carboxylic acid, a salt of a carboxylic acid, a carboxylic acid anhydride or a carboxylic acid halogenide, and at least one peroxo compound, and/or b) at least one percarboxylic acid, wherein the composition contains at least one heavy metal and/or one heavy metal compound. The presence of a heavy metal/heavy metal compound causes an adequately fast decomposition of the percarboxylic acid after the percarboxylic acid has achieved the desired cleaning and disinfecting effect. The composition is especially important as a contact lens cleaner, where on the one hand thorough cleaning and disinfection of the contact lenses is essential, but on the other hand contact of the solution with the eyes or the skin of the user should not lead to irritation or serious injury.

SYSTEM AND METHOD FOR CULTIVATING AND HARVESTING MUSHROOMS
The invention relates to a system for cultivating and harvesting mushrooms, with a plurality of picking racks (5) which are located in a picking zone (6), wherein the mushrooms, which grow on a substrate (3), are arranged on one level on the picking racks (5). The problem addressed by the invention is that of providing a cultivating and harvesting system, with which the picking costs can be reduced. For this purpose, the invention proposes providing at least one transverse conveyor (17) in the picking zone (6), this involving a belt conveyor which spans a plurality of picking racks (5) arranged next to one another and has a conveying direction transversely with respect to the longitudinal extent of the picking racks (5).
The invention relates to an implant for anchoring a prosthesis in the jaw of a patient, having a base body (1) and a post (2) connecting to the top thereof, wherein the post (2) engages in a recess opening (3) of the base body (1) in a positive and non-positive manner and can be firmly connected thereto. In order to improve such an implant, the invention provides that a sealing collar (4) surrounding the recess opening (3), and an annular groove (5) surrounding the sealing collar (4), are provided on the top of the base body (1), wherein the post (2) has a circumferential shoulder (6) on the bottom thereof facing the base body (1), the shoulder having a shape that is complementary to the sealing collar (4) and the annular groove (5).

METHOD FOR THE PRODUCTION OF A CONCRETE CONVEYING PIPE
The invention relates to a method for producing a conveying pipe (1) for concrete or other thick matter having highly abrasive properties. According to said method, coupling flanges (2) are first welded onto the ends of a pipe (1) made of hardenable steel, and an internal layer (5) of the conveying pipe (1) is then created by means of a hardening process in such a way that the internal layer (5) is surrounded by a non-hardened, impact-resistant external layer (6). The hardening process is performed by means of induction hardening with the help of an induction head (7) which is introduced into the pipe (1). The induction head (7) and the pipe (1) are moved relative to one another in an axial direction during the hardening process, the effective hardening depth of the induction hardening process being controlled in accordance with the momentary position of the induction head (7) in the pipe (1). Preferably, the effective hardening depth is greater in the final areas than in the central area, thus providing the pipe with great resistance to wear.
