Abstract: Apparatus for feeding sheets one by one from the bottom of a stack of sheets comprising first and second spaced supports cooperatively supporting the bottom of a stack of sheets, the first support comprising a rotatable unit and the second support comprising a flat abutment member. The rotatable unit includes a plurality of juxtaposed rollers at least one of which is intermittently rotated to feed the lowermost sheet in the stack to a conveyor. The flat abutment member is adjustably supported for displacement to a selected predetermined stationary position. The rotatable roller is coupled to a suction device so that suction force is applied to the lowermost sheet in the stack in the course of intermittent rotation and the position of the roller with the conveyor belt is such that the suction will be substantially reduced when the sheet has been received by the conveyor belt.

Abstract: Hash-coding storage arrangements are known which are capable of storing data values efficiently and permitting rapid testing of whether a given data value is stored. However, such arrangements may produce erroneous outputs. The invention reduces or eliminates these erroneous outputs by providing a further store (which may itself be a hash-coding storage arrangement) which identifies the erroneous outputs, and is used to suppress them.

Abstract: An integrated switching and transmission of PCM words associated with channels and transferred on links utilizing the time-time switching principle is achieved by connecting an interhighway, i.e., a common time multiplex connection on which the PCM words are transferred in bus time slots, to inward and outward traffic memory arrangements each associated with one of the links. The memories store the words and in addition not only store, for each established connection channel, index numbers indicating the actual incoming and outgoing channel, but also a time index number indicating which bus time slot during an index read out phase is used for the connection. The phases are introduced in order to avoid the necessity of using memory access times corresponding to the bus time slots. Each phase comprises a number of bus time slots and each frame of the PCM words includes at least so many such phases as there are channels on each link.

Abstract: A central control unit is connected via a common bus system to a number of function units, each of which being furnished with redundant address decoders in order to ensure reliable selection of the function units. If, in response to an address which is sent out by the control unit, a signal is emitted by only one of the two address decoders of a function unit, a recording is made in a memory device corresponding to that decoder to indicate an erroneous condition in one of the address decoders of the addressed function unit. If, on the other hand, signals are emitted by both address decoders a check signal is returned to the control unit, the absence of the check signal indicating that either one of the decoders belonging to the addressed function unit is faulty. Error recordings are read out from the respective memory device by subsequent addressing of the units, the read out from the memory device belonging to the one address decoder being effected by the signal emitted by the other decoder and vice versa.

Abstract: In a display device having a record medium which is parallel-line raster scanned by a beam which is intensity modulated to form matrices of dots representing symbols, apparatus is provided to generate composite symbols such as characters with diacritical marks. The apparatus includes a source of groups of coded combinations of bits representing symbols with each group having a first part representing the character and a second part the diacritical mark. A first addressable memory stores the binary signals representing the dots of the character while a second addressable memory stores the binary signals representing the dots of the diacritical marks. Thus, each symbol group addresses two memories which then feed these binary signals to the beam which is intensity modulated to form a matrix of dots on the record medium. In addition provision is made to vertically displace the characters to perform subscripting and superscripting.
