Patent DE-3123616-A1 (DE)
Title: Method for preventing blockages of connection-specific devices
Inventor: SCHERER MANFRED
IPC: H04Q3/42
Filed: 1981-06-13
Abstract: In an indirectly controlled telecommunication switching system, particularly a telephone switching system, comprising a memory with storage areas permanently allocated to the subscriber lines and the connection-specific devices, into which, in addition to other information items, the addresses of the further subscriber lines and devices involved in the connection concerned are entered during the setting-up of a connection, the further subscriber lines and devices involved in the connection concerned are determined during the releasing of the connection and it is checked whether the storage areas concerned in each case contain the address or addresses of the further subscriber lines and devices involved in the connection. In a case of non-agreement, a diagnostic programme is started which determines the missing address by searching the memory. It is only then that the device concerned is released in the memory. This avoids a blockage of connection-specific devices when the address of a device involved in a connection which is falsified by a disturbance is entered in the memory.

Title: Damping spring arrangement
Inventor: POPP KARL-HEINZ
IPC: F16F15/04
Filed: 1982-05-10
Abstract: The invention relates to a damping spring arrangement. In order to achieve an improved springing and damping quality with relatively short spring movements, relatively low spring rates and a relatively small constructional cost, the damping spring arrangement has a load roller which can roll off on a lever that is spring-pretensioned and is provided with a straight or curved running surface, can be displaced by the load and is guided in the load direction between the lever and an opposing bearing. The radius of curvature of the curved running surface of the curved lever on which the load roller rests is larger than the radius of the load roller. Furthermore, compensation rollers are provided which are arranged such that they can rotate freely about the axis of the load roller, or are arranged at a distance from the load roller, and rest so that they can roll off in the opposing bearing. The opposing bearing can likewise be a lever on which a curved running surface is constructed for the compensation rollers. The levers are double levers whose two lever arms can pivot about a fixed-position rotation point and are pretensioned by springs in the opposite direction to the torque which is exerted on the levers by the load roller, or if applicable by the compensation rollers. The position of the springs which act on the lever arms is variable with respect to the lever rotation point. <IMAGE>

Title: Process for operating a gypsum/sulphuric acid plant
Inventor: GOSCH HANS-WERNER
IPC: C04B7/04
Filed: 1982-06-18
Abstract: In this process, conversion of the gypsum serving as feedstock into anhydrite in a separate plant is omitted. Instead, the gypsum is first subjected only to partial dehydration down to a surface water content of 10-15% by weight. A two-step drying and calcining of the gypsum is then carried out in which the SO2-containing waste gas of the furnace is used as heat-transfer medium. At the same time, dust is removed from this waste gas to such an extent that it can be passed without any further gas treatment into the gas scrubber of the sulphuric acid plant. After passing the second drying step, the dried and calcined gypsum still has a total water content of about 6% by weight and is passed directly together with the addition materials via a conveying element into the heat-exchanger of the furnace, so that the furnace powder is mixed in the conveying element and/or heat-exchanger.

Title: Contactless current collector device for magnetic cushion train
Inventor: IWAHANA TAKEHIKO
IPC: B60L5/00
Filed: 1982-10-08
Abstract: The invention relates to a contactless current collector device for magnetic cushion trains in which the harmonic components of the magnetic counterflow, which components are generated by basic lifting coils, are used to generate the electrical power required by electrical loads such as the air-conditioning system and lighting system in the train. For this purpose, the device according to the invention contains a multiplicity of current collector induction coils (2) which are arranged on the train body opposite the basic lifting coils (6), the voltage induced in the current collector induction coils by the harmonic components of the magnetic counterflow, said components being generated by the basic lifting coils (6), passing to a power converter which supplies the power required by the electrical loads such as the air-conditioning system and lighting devices. According to the invention, the individual current collector induction coils (2) have different winding numbers which are dependent on the level of the induced voltage which is produced as a result of the arrangement in a chain of the harmonic components of the basic lifting coils with the current collector induction coils. As a result, the weight of the individual current collector induction coils is compensated with respect to their power drain so that the electrical power is absorbed with a high degree of efficiency. <IMAGE>
