Patent DE-3248346-A1 (DE)
Title: Entrance for vehicles, especially rail vehicles
Inventor: PIETROWSKI EDMUND ING GRAD
IPC: B60R3/02
Filed: 1982-12-28
Abstract: The entrance for rail vehicles is designed to be adjustable to correspond to platform height, so that it can be used at stations with platforms of different heights. To permit entry from a high platform, the movable step, which is composed of two parts which are articulatedly connected to one another, forms part of the completely level floor which extends right up to the side of the vehicle. To permit entry from a ground-level platform, a drive is used to fold the movable step downwards, to form, together with a fixed lower step, a three-part entrance. The design of the entrance according to the invention is intended to ensure that the individual components, which have hitherto been physically separated, are now brought together to form a coherent whole in the entrance section, in order to permit rapid assembly. The assembly is also to be designed in such a way that, in the region of the entrance section, it transmits the compressive and tensile forces which are imparted to the underframe. This is achieved in that the fixed step is mounted on a rigid frame, the rear cross member of which supports upwardly pointing beams for the rotatable mounting of the movable step, the connection of the frame to the vehicle being such that the beams are suspended in the floor of the vehicle and the lateral cross members are releasably fastened to the vehicle.

Patent DE-3323752-A1 (DE)
Title: Automatic emptying when not in use, and possibility of turning off individual parts of a solar collector
Inventor: COST KARLFRIED
IPC: F24S10/50
Filed: 1983-07-01
Abstract: Description:     a)Automatic emptying when not in use The water outlet in the type of solar collector described in the main patent does not lie at the lowest point, thus water always remains in the collector or in the individual partial regions. A small additional outlet is provided at the lowest point of each partial region, through which water constantly flows out. This quantity of water is small in comparison with that in the main outlet and only slightly changes the functioning of the collector. After the water supply is turned off, the collector runs empty.   b) Turning off of partial regions When a partial region of the collector is damaged, a given point in the collector is blocked off. The water is dammed up and flows via a bypass path into a partial region which lies lower down. The collector remains able to function, even with a defect in partial regions. The shut-off path integrated into the collector and the integrated bypass are cheaper and less liable to give trouble than individual components placed externally (e.g. hoses, taps).   <IMAGE>
Patent DE-3324163-A1 (DE)
Title: Radio teleprinter tuning aid on computer monitors, displays or terminals
Inventor: SCHAEFER WOLFGANG
IPC: H03J1/04
Filed: 1983-07-05
Abstract: Radio teleprinter tuning aid on computer monitors, displays or terminals. The aid is used for simple, fast and time-saving precision- tuning of the receiver. It eliminates the need for laborious turning backwards and forwards of dials while tuning the converter to achieve precise tones which are to be transmitted via the teleprinter or computer. The intention of the concept is to provide the radio amateur working with a computer RTTY with the facility for reducing circuit costs in the converter whereby, since he now has the display directly in front of him on the monitor, he can concentrate during operation on the monitor alone and does not have to observe yet another device. The tuning aid comprises a cross or other symbol which is now fed by the converter to the computer or monitor. If the transmission produces a sharply defined cross on the monitor, the receiver tuning is correct in terms of frequency. The converter now provides the computer with signals which the latter can evaluate and convert into letters, numbers and symbols. If the symbol on the monitor is blurred, the receiver needs to be retuned.

Title: Steam generator with evaporator pipes connected in parallel
Inventor: LOESEL GEORG ING GRAD
IPC: F22B29/06
Filed: 1984-03-12
Abstract: The invention relates to a steam generator (7, 16) with evaporator pipes connected in parallel, which start from a common inlet manifold (8, 39) and open out in a common outlet manifold (9, 40). In such steam generators, there are in certain operating states considerable temperature variations between individual pipes, which variations sometimes lead to the destruction of the steam generator. In order to reduce these temperature variations, the invention envisages that evaporator pipes (1 to 6, 17 to 38), in which these instabilities arise, are interconnected via pressure compensation pipes (10, 11, 43 to 57). The pressure compensation pipes can interconnect evaporator pipes in which the maximum amplitude of the flow rate is mutually phase-displaced by approximately 180 DEG . A steam generator according to the invention is particularly suitable for use in large-scale furnace installations. <IMAGE>
