Patent DE-3106932-A1 (DE)
Title: Support structure of fixed design (stator) for the storage compound of regenerative tempering coil heaters having a perpendicular shaft
Inventor: SANDMANN HERBERT DIPL ING
IPC: F28D17/02
Filed: 1981-02-25
Abstract: In regenerative tempering coil heaters with a large diameter of 5 metres and more for power stations, the high air losses are caused by deformation of the heating surface carriers. The bulging of the end faces is represented by dashes in Figure 1. Use is made of the most varied auxiliary devices in attempting to reduce the large sealing gaps produced. According to the present invention, however, the stator is to be built such that bulging is avoided. As Figure 2 shows, only the radial walls bend slightly. It is necessary to connect the core displaceably to the radial walls, and to provide the stator housing additionally with internal insulation of such strength that the conical shape of the stator casing is in accord with the angle  alpha  of inclination of the curved radial walls, as Fig. 3 shows. The upper casing part is surrounded by a cooling air annular duct in order to regulate the desired conicity. Fig. 4 shows the annular duct (16) on the casing (1), and the housing connecting flange (12), which is connected by joints (13) to the insulated stator flange (2). The internal insulation is denoted by (20). <IMAGE>

Title: Absorber rod drive with plug-in connector
Inventor: MUNDT DIETRICH ING GRAD
IPC: G21C7/12
Filed: 1981-04-30
Abstract: A drive for the absorber rod in a pebble bed reactor, which by means of a motor (3) and a transmission (4) having two outputs can be both rotated by a rotating tube (12) and moved up and down by means of a spindle drive (21, 22). For maintenance purposes, the drive can be detached by lifting it axially out of the plug-in connectors (5, 8, 14, 16). In order to facilitate renewed plugging together of the connectors later on, their teeth (6, 7, 15, 17) are pointed in a wedgelike fashion. The connectors are permanently lubricated, since with the aid of special extensions (9, 18) cup-like chambers are provided which can be filled with lubricant. If a spring (28) is unloaded by lifting off the upper part (14) of one plug-in connector, which presses down a plate (27), this causes closure of a locking mechanism (29, 30) which prevents mutual rotation of the rotary drive (12) and spindle drive (21, 22). <IMAGE>

Title: Blade flow techniques and blade shapes for increasing efficiency by using the vortex-flow speed change effect in vortex-flow blades and the associated energy conversions in vortex-flow centrifugal pumps and exhausters
Inventor: REIBER KURT
IPC: F04D29/24
Filed: 1981-05-11
Abstract: Blade flow techniques and blade shapes for increasing efficiency by using the newly discovered vortex-flow speed change effect in vortex-flow blades and the associated energy conversions in liquid and gaseous media. Vortex-flow blades have semicircular or, for wall-free flow, hemispherical shell shapes with possible partial deviations. When flowed through in a controlled manner, moved vortex-flow blades in turbines have a flow-decelerating effect while, in centrifugal compressors, they have an accelerating effect with a virtually ideal energy conversion effect, whether this is the conversion of energy of flow into blade energy or vice versa. Technical applications are:   1. Vortex-flow blade centrifugal pumps as such, as gas compressors, exhausters, directional fans, as a cold jet drive for aircraft, land vehicles, water craft and underwater craft - as well as two-wheeled vehicles, as a turbocharger and as a suction device. 2. Vortex-flow blade turbines as gas and liquid turbines of all sizes. In addition an ultra-speed water turbine in which hemispherical-shell turbine blades cut the total turbine water consumption continuously from the inner vortex-flow pressure head. Also suitable as a wind turbine.   3. Pelton-type vortex-flow turbine as a water and wind turbine.   4. Skimming blade for floating oil, for use against oil pollution. The drawing demonstrates the flow-accelerating effect in vortex-flow blades by in each case twice the speed of the working-blade rings. <IMAGE>

Title: Deformable seal of the gap between a building opening and a vehicle which has been driven up to said opening
Inventor: ALTEN KURT
IPC: B65G67/00
Filed: 1981-08-03
Abstract: In the case of said seals there is located, between a downwardly open U-shaped frame for fastening a deformable apron, on the one hand, and the building, on the other hand, a covering which, owing to articulation on linking members, is deformed in the event of action on the apron and a resulting slight displacement movement. In order to eliminate disadvantageous deformations of the covering, that edge of the covering which is directed towards the building is guided such that it can be vertically adjusted. The resulting tension compensation in the covering is effected by arranging the edge in a perpendicular, undercut groove.
