Title: Pollutant separation from bituminous mixt. - uses solids to form movable filling of gas filter in drum drier
Inventor: WERNER WILLI
IPC: E01C19/05
Filed: 1979-07-21
Abstract: The process separates dusty or gaseous pollutants from a mixture of solids and bituminous binder during treatment in a drum drier. The gases containing the pollutants are passed through a conventional laminated filter, containing fibrous or granular material. At regular intervals the filter is cleaned by shaking and/or wet flushing until a preset lower flow resistance is reached. The loose material used to fill the filter (7) is part of the granular solids subsequently used to produce the mixture. The cleaning effect is produced by the solids rolling and sliding by gravity. The lower flow resistance through the filter layer (11) is determined by their packing, in conjunction with the speed at which they flow through it. The flow is halted as long as the flow resistance to the gases through the filter is below an adjustable, preset value.

Title: Control circuit for telephone subscriber special functions program - has electrically alterable multi-word store resettable by single command signal
Inventor: KRETZ HANS-JOACHIM ING GRAD
IPC: H04Q3/62
Filed: 1980-05-13
Abstract: The method is for inserting a particular auxiliary function into the connection program of a telephone switching system (such as for example, repeat dialling, call transfer, etc.), as well as for cancelling the function at any time by a reset signal from the same subscriber station (T1n). It comprises, apart from the central control unit (ZSE), a peripheral unit (PE) and a standard couple field (KF). An electrically alterable data storage circuit (AS) receives instruction data via a central processor (ZRE) and input buffer (EP) from the peripheral unit (PE). A control register (AR) causes the encoded functions stored in terms of data words to be read out one by one from the storage unit (AS) and checked against the presence of a flag signifying the subscriber (T1n). To perform a function deletion there must be identity between the incoming deletion command signal and the flag in the readout function word. The working register (AR) which performs the comparison, controls the sequence of the deletion from the addressed memory locations in the storage unit (AS). A completion signal is released when all deletable functions are emptied. A buzzer indicates empty of all special functions. An engaged signal indicates empty of all subscriber-originated functions.
