Title: Mould, in particular steel mould, for producing objects by the concrete-centrifuging process
Inventor: BONATO EMIL
IPC: B28B21/80
Filed: 1985-05-07
Abstract: The mould (1) is designed as a steel mould and is used for producing objects by the concrete-centrifuging process. The longitudinal flanges (4, 5) can be braced with respect to one another by clamping devices (6) which can move in the direction of the longitudinal axis (1a) of the mould (1) and have oblique running-on surfaces. A simple longitudinal movement in the direction of the longitudinal axis (1a) of the mould (1) is sufficient to brace the two part-shells or half-shells (2, 3) of the mould firmly to each other, it already being ensured, in design terms, that the longitudinal flanges of the mould are, in a single operation, automatically braced firmly to each other in a uniform manner at all points. The clamping work is also considerably simplified as a result and substantially reduced in terms of time. Re-adjustments of the clamping devices are not necessary. <IMAGE>

Title: Mineral fibre product as insulating panel or insulating web
Inventor: FURTAK HANS DR ING
IPC: B32B7/022
Filed: 1985-06-01
Abstract: Mineral fibre products often contain, for the purpose of surface finish, at least one cover layer, for example as protection against crumbling, optical facing or as protection against flowing media. The present invention proposes, on the other hand, a mineral fibre product in the form of an insulating panel or insulating web in which a pressure-distributing cover layer (glass non-woven fabric 3) is provided which, depending on the application, ensures the required dimensional stability of the product, the density of the mineral fibre layer (2), on the other hand, preferably needing to be designed only according to the conditions of a specific thermal conductivity group. In particular, in the case of insulating panels (1) for back-ventilated façades, for example, better handling, pressure distribution and resistance to detachment in the case of dowel fastening (6) etc., are obtained. <IMAGE>
Patent DE-3519934-A1 (DE)
Title: Core for a high-temperature nuclear reactor
Inventor: KUGELER KURT PROF DR ING
IPC: F02B1/04
Filed: 1985-06-04
Abstract: A novel core geometry is proposed in order to keep the accident temperature of a high-temperature nuclear reactor lower by comparison with a nuclear reactor fitted with an equal-area conventional core. Said geometry is distinguished by shorter guide paths for the dissipation of heat and offers, furthermore, substantial advantages in the component arrangement and in the possibility of selecting the charging mode. As a result, it is also possible for the production costs for a high-temperature nuclear reactor fitted with such a core to be kept substantially lower. <IMAGE>

Title: Sliding-ring seal for socketed-pipe connections
Inventor: MUECHER HORST
IPC: F16L21/035
Filed: 1985-06-12
Abstract: In the case of a sliding-ring seal for socketed-pipe connections, the tip end on whose radial outer wall an elastic sealing ring is preinstalled has a centring ring which is located axially at a predetermined distance in front of the sealing ring, or has a retaining ring which is connected to the sealing ring. Both rings, which are used alternatively, preferably consist of a material which is harder than the elastic sealing ring. They engage around the end wall of the tip end, running radially inwards a small amount, and, at the start of their axial extent, have a radially outwardly expanding conical centring surface or, instead of this, have a radially externally located centring curvature, both of which are suitable to ensure adequate centring of the tip end in the socket during installation, by interaction with the inner edge of the socket and/or with that part (which tapers radially towards the shear-load bearing) of the inner wall of the socket of the previously laid pipe.
Patent DE-3522333-A1 (DE)
Title: Vibration damper, especially in conjunction with elastic bearings
Inventor: BEBERMEIER JUERGEN DIPL ING
IPC: F16F13/08
Filed: 1985-06-22
Abstract: Elastic engine bearings, shock absorbers and other spring systems are equipped in accordance with known proposals for the suppression of undesired oscillations with a hydraulic damping device in the form of a flat disk which is pulled through a damping fluid, with axial play. According to the invention, a plurality of disks are provided whose surface area is stepped and with a free path which increases in proportion with their size. It is thus possible to make the deceleration force uniform over the entire braking path within the damping fluid, and to keep it virtually constant in all regions.

Title: Access security device
Inventor: RAISER ALFRED
IPC: F02M3/10
Filed: 1985-08-06
Abstract: A device is proposed for protection against unauthorized access. Two covering caps (1, 2) are connected to one another by means of connecting webs (36) which are used as part of an assembly aid (3). When the covering caps (1, 2) are pressed into the component which is to be protected against unauthorized access, the covering caps (1, 2) are separated from the assembly aid (3) by shearing off at connections (37) having a small cross-section. At the same time, the covering caps (1, 2) latch by means of claw bodies, which are mounted on webs (19), on retaining bodies which are firmly connected to the component to be protected, at least partially engaging around said retaining bodies. Thereafter, separation of the covering caps (1, 2) from the component to be protected is now possible only by destruction of the covering caps (1, 2). <IMAGE>

Title: Purlin of cold-rolled sheet metal for a pitched roof
Inventor: HUELLE HANS PETER
IPC: E04B7/02
Filed: 1985-09-12
Abstract: The purlin is composed, in profile, of a web (4), an upper flange (5) and a lower flange (3), both of which form an angle of 90 DEG  with respect to the web. The upper flange is single, is directed only to one side and ends, at an angle of 90 DEG , in the form of an end portion (5a). The lower flange projects to the opposite side in the form of a double flange portion (3a) and extends to the side of the upper flange singly as flange portion (3b) which likewise ends in a bent-up end portion (3c). While the web (4) forms an angle with the vertical corresponding to the roof pitch, the surfaces are divided such that the reference axes for the geometrical moments of inertia run vertically and horizontally. As a result, an optimum load-bearing capacity is achieved with respect to vertical loadings. <IMAGE>

Title: Sheathing for load-suspension aids
Inventor: FABRITZ GERHARD
IPC: B66F9/12
Filed: 1986-03-07
Abstract: The invention relates to a simple sheathing, which is quick and easy to assemble, for load-suspension aids such as, for example, forks of fork-lift trucks or coil hooks. In aids of this type, it is necessary during the handling of potentially explosive goods to sheath the aids with plastics or similar materials in order to avoid sparking. The methods known for this purpose are not only expensive but also time-consuming. According to Figs. 1 and 2, the sheathing consists of an elongated flat envelope 1 of rectangular cross-section. At the open end of the envelope, preferably made of rubber, its narrow sides are interrupted by slots 2. Thus two bendable lobes 3 and 4 are obtained, on the longitudinal sides of which connecting parts are vulcanised in place. These connecting parts are hooks 5 and eyes 6. Fig. 3 shows the sheathing of the fork 7 of a fork-lift truck. Here, the envelope 1 is pushed over the fork 7, whereas the lobes 3 and 4 are firmly connected to one another by means of hooks 5 and eyes 6 after the bending. The lobes can also be connected by means of zip fasteners attached to them. Finally, angular recesses facing one another but staggered can be made according to Fig. 4 on the sides of the lobes. U-shaped straps can be inserted into these recesses so that the lobes are firmly connected to one another by means of the straps. To pull the envelope onto a load-suspension aid ...

Patent DE-3618428-A1 (DE)
Title: Fluidised-bed furnace
IPC: F23C10/10
Filed: 1986-05-31
Abstract: In known fluidised-bed furnaces, the combustion air, if appropriate together with recycled flue gas fractions, is blown as primary air into the plant underneath a gas/solid fuel separation zone; this primary air here effects both fluidisation of the fluidised bed and, as oxygen carrier, the combustion thereof. Such fluidised-bed furnaces, matched to a defined output and a defined fuel, are not very variable. According to the invention, a gas stream of a flue gas/air mixture passing through the gas/solid fuel separation zone consists preferably of flue gas and effects the fluidisation of the fluidised bed, whereas a second gas stream of an air/flue gas mixture as oxygen carrier is blown into the fluidised bed above the gas/solid fuel separation zone and/or into the flue gas stream above the fluidised bed. Due to the separation of the gas streams, the fluidised-bed furnace can be adapted rapidly and without problems to changed fuels and outputs; likewise, the combustion temperature and emissions of pollutants can be influenced.
