Abstract:
The invention relates to a thermal energy accumulator (10, 50, 70, 80, 90) that comprises a large-volume storage tank (12) for storing a storage medium (18) and that is arranged in the ground during use, wherein the storage tank (12) comprises an inner tank (14) and an outer tank (16). The inner tank (14) is made of a temperature-resistant thermoplastic plastic, and the outer tank (16) is made of a pressure-resistant thermoplastic plastic. A thermally insulating material is arranged in an intermediate space (20) between the inner tank (14) and the outer tank (16).
Abstract:
The invention relates to a closing element (10) that comprises a blow moulding element which is made of plastic and produced by means of a blow moulding method. The blow moulding element has at least two supports (12, 14) and at least one transversal bar (18) which is arranged essentially transversal to the supports (12, 14). At least one recess (36a to 36h) is provided in the transversal bar through which an adapter element (120) can be connected to the closing element (10), said adapter element being configured in a complementary manner in at least one region to the recess (36a to 36h).
Abstract:
A device and a method for producing preforms (34) from thermoplastic material comprise an extrusion head having a sleeve (12) and a die head (14). A closing device (24) closes the outlet opening (20), so that a bottom for the preform (34) forms between the sleeve and closing device. In the open state of the closing device (24), the preform (34) is ejected together with the bottom out of the outlet opening (20). In this way, a pinch-off weld is avoided in the bottom region of the preform.
Abstract:
The invention relates to a method for activating a vitamin K-dependent blood factor by treatment with a protease derived from plants or procaryotes. The invention also comprises the blood factor produced according to the invention, which shows no animal protease contamination, as well as a pharmaceutical preparation and a set for medical application.
Abstract:
The invention relates to a method and to a device for producing a boat-type body (10) of a water sport device. According to the invention, a rotating frame (12), which is pre-formed about an access opening of the boat-like body (10), is arranged on an inner side of a negative mould. The outer shape of the boat-type body (10) is predetermined, essentially, by the innerside of the negative mould. The boat-like body (10) is produced in the inner side of the mould by means of a thermoplastic shaping method. During the shaping process, at least one part of the surface of the rotating frame (12) is in contact with the boat-like body (10) which is formed by the thermoplastic shaping method. The invention also relates to a water sport device.
Abstract:
Disclosed is a container comprising a plastic inner receptacle (10) that is provided with at least one top filling port (12), an outer support body (16), and a pallet (24) upon which the inner receptacle (10) sits. The outer support body is configured as a grid-shaped sleeve element (16) which is provided with vertical U-shaped profiles (18) that are connected to each other by means of steel wires (20) extending in the circumferential direction of the sleeve element (16).
Abstract:
The invention relates to a method for verifying the leakproofness of a container used for accommodating preferably liquid media as well as a plastic container that is composed of several segments (22a, 24). The invention further relates to a method for producing a container from several segments and a container comprising a closed barrier layer. The disclosed container is composed of at least two segments (22a, 24) which are joined together circumferentially at the edges of the faces thereof by means of one respective welded connection (16, 17) such that an enclosed space is formed. An inner pressure that is different from the ambient pressure is applied within the enclosed space while a change in pressure is monitored.
Abstract:
The invention relates to a device for storing liquids comprised of a plastic container, which is produced by a blowing process, which has a single layer or multilayer wall, and which is provided with at least one filling and emptying opening. The aim of the invention is, on the one hand, to economically manufacture a device of the aforementioned type by using inexpensive forming tools and, on the other hand, to be able to transport the device from the production site to the storing site also without incurring large expenditures. To this end, the container (1) is formed from at least two separately manufactured and largely identical container parts (2, 3), each of which comprising an approximately rectangular cross section with an underside (4) and a upper side (5) and having a height that is considerably greater than the largest cross section measure. Each of the container parts also have, on one side, a lower and an upper flow socket (10, 11), and are joined to one another in the area of these flow sockets (10,11) whereby forming one piece.
