Abstract: A method for transmitting equipment-specifying program parameter data from a communications installation to communications terminal equipment. The method provides for transmitting program parameter data from a communications installation to a plurality of communications terminal equipment connected thereto and is based on a message-oriented transmission protocol that is used in the sense of an information exchange in the signalling channel between the equipment. In the communications equipment, the input and output devices as well as the procedures of performance features and local performance features are essentially controlled with the assistance of the program parameter data. A transmission of program parameter data is initiated either by a parameter request message transmitted from the communications terminal equipment or by an internal request of the communications installation. In a start of parameter message, address and parameter defining criteria are transmitted from the communications installation to the respective communications terminal equipment. Subsequently, the program parameter data embedded into a parameter message are transmitted to the respective communications terminal equipment and are stored in them.

IPC: D21C5/02

Abstract: A de-inking and bleaching process for waste paper is described, which is operated without or with only minimal quantities of chemicals, especially alkali, in the pulper. After a first printing ink removal, for example by means of washing, a 2-stage bleach is carried out, preferably using the peroxide/ formamidinesulphinic acid (FAA) combination. After the 1st bleaching stage with peroxide, the pH is in the alkaline region at about 8.5 - 9.5. At approximately stoichiometric ratios of alkali and FAA, the pH in the medium is in the neutral region at 6.5 - 7.5 after the 2nd bleaching stage, without additional acidification being necessary. As a result, the purification of the circulating waters, for example by means of release flotation, is substantially facilitated. The 2-stage bleach is carried out, for example, as a combination of disperser bleach and bleach at medium stock consistency. After the disperser treatment, or after the bleach, a further removal of printing ink and dirt is carried out, for example by flotation or washing, nonionic frothing/collecting agents also having proved suitable. Residual peroxide from the 1st bleaching stage, which would destroy the FAA used in the 2nd bleaching stage, can not only be made harmless by addition of thiourea, but advantageously be converted to additional FAA. <IMAGE>

IPC: G06F9/46

Abstract: In a multiprocessor system, a communication register is partitioned into groups of word storage locations and one of the groups is further partitioned into subgroups associated respectively with the processors. An access controller accesses any groups of the communication register when a system program is being processed and accesses one of the subgroups when a user program is being processed. A write controller is responsive to a test & set instruction of first occurrence from a common bus for assembling a lock word with a data word, a control field and a counter field containing a variable count. The control field of the lock word is set to a first binary state when it is assembled and reset to a second binary state when deassembled. In response to a load instruction from the common bus, either the data word from the bus or lock word is stored into a specified storage area of a communication register. A read controller reads contents of an addressed location of the communication register onto the common bus in response to a save instruction. Test & set instruction of a subsequent occurrence causes the variable count in the stored lock word to be decremented as long as the control field remains set to the first binary state. When the count reduces to zero, a signal is applied to the common bus indicating the occurrence of a dead lock.

Abstract: An animal-resistant optical fiber cable (20) includes a core (22) which comprises a transmission medium and a sheath system. The sheath system includes an outer jacket (65) and a dielectric armor (40) in the form of a shell. The shell comprises a plurality of longitudinally extending preformed segments (42-42) each having an arcuately shaped cross section transverse to a longitudinal axis of the cable and each comprising glass fibers embedded in a matix material. Each of the segments covers less than half of the periphery of the core and, in a preferred embodiment, eight segments are used. Further, the shell segments are stranded helically about the core with longitudinal edge surfaces of adjacent segments being in engagement with each other. The shell segments not only provide rodent protection for the cable, but also they provide suitable tensile and compressive strength. Further, because the cable has an all-dielectric sheath system, it is inherently lightning, corrosion and EMP resistant.

Abstract: Very low viscosity polymer polyols having high styrene/acrylonitrile ratios and good stability are obtained by a process comprising polymerising, via a free-radical reaction, a monomer component, in the presence of a polyol mixture comprising a major portion of a base polyol unmodified with epoxy resin and a minor portion of an epoxy resin-modified polyol as a dispersant. The epoxy resin-­modified polyols useful as dispersants may be made by reacting a polyol initiator having an active hydrogen functionality of 3 to 8 and one or more alkylene oxides with an epoxy resin. It is preferred that all of the epoxy resin-modified base polyol dispersant be initially charged to the reactor, along with part of the base polyol.
