Patent DE-3220881-A1 (DE)
Title: Method and apparatus for laying pipes in foundations
Inventor: GEYER EBERHARD
IPC: E03F3/06
Filed: 1982-06-03
Abstract: The invention "method and equipment for laying sewer pipes in foundations in residential, commercial and industrial building" is a new productive technology which eliminates the considerable disadvantages of known technical solutions and contains the equipment necessary for their implementation. Special mountable pipe-supporting slabs are mounted, on a mounting plane prepared at the exact slope of the sewer pipes, on the bottom of a foundation trench. Using a special formwork system, the foundation slab serving as a boundary of the conduit is concreted. After laying the sewer pipe with all the necessary mouldings on the pipe-supporting slabs, the conduit is closed using covering slabs laid by hand. Two special covering slabs lying against one another and having semicircular surfaces are positioned over each of the connection pieces, through which covering slabs the downpipes are introduced into the connection pieces. The cleaning-opening accesses are also made in this shape, so that the arrangement of shafts is dispensed with. This invention is particularly important for the trouble-free laying of pipelines made of pipe materials hitherto uncommon for these purposes, such as glass pipelines with glass mouldings which have specific advantages such as low roughness value, high hydraulic capacities, low pipe longitudinal inclination and hence smallest stressed constructional space.

Patent DE-3309209-A1 (DE)
Title: Captive line for connecting a plurality of parachutes
Inventor: PALLOKS ARMIN
IPC: B64D17/74
Filed: 1983-03-15
Abstract: A captive line between parachutes contains a tension shock absorber for damping the strain shock which occurs suddenly when the canopy fills. The tension shock absorber consists of a winding of the captive line which is designed as a belt, which winding is held by means of at least one securing line which covers the stack of belt layers which rest one on top of the other between the centre and the circumference of the winding, and results in the belt ends being able to run off from the winding only under the damping friction force. In the event of continuous rotation of the winding from its centre, said line becomes twisted and hence becomes retensioned in a corresponding manner as the diameter of the winding becomes smaller.

Patent DE-3316144-A1 (DE)
Title: Method and device for measuring the extent of a movement
Inventor: SUEDA TETSUO
IPC: G01D5/38
Filed: 1983-05-03
Abstract: By means of a diffraction grating (1) which serves as an absolute dimension, bundles of diffracted light which interfere with one another are generated in order in this way to determine the extent of the relative movement between the diffraction grating (1) and the remaining optical system (3, 9, 8). Bundles of diffracted light of the same order with different sign are formed upstream of the diffraction grating, and two reflecting mirrors (11, 12) cause the respective bundles of diffracted light to retrace the forward run and re-enter the diffraction grating (1), so that further bundles of diffracted light of the same order with different sign are generated. These two bundles of diffracted light are caused to interfere, in order in this way to measure the extent of the movement of the diffraction grating. <IMAGE>

Title: Quick-action mandrel for machine tools
Inventor: MOOSMANN JOSEF
IPC: B23B31/40
Filed: 1983-05-17
Abstract: This quick-action mandrel enables mandrels to be reduced in size and the internal clamping of workpieces to be simplified. The workpiece with a cylindrical, conical or stepped bore is clamped continuously between conical clamping surfaces on the mandrel and a slip-on clamping sleeve. For narrow workpieces the clamping sleeve is equipped with a supporting member and can be used either way. With the mandrel accommodated between the tips, the clamping sleeve is stopped by means of cross-screws. Clamping members are formed on the clamping sleeve for accommodating pincers. When both tip pressure and clamping pressure are employed the clamping sleeve is accommodated in the pincers and the mandrel together with the workpiece is inserted into the bore of the clamping sleeve. The tip pressure effects a rapid clamping of the workpiece through the tip, mandrel, workpiece and sleeve.

Title: Process for the elimination of polluting organic substances from liquids and for the regeneration of the adsorbents used in this
Inventor: BENDER HEINRICH
IPC: C02F1/20
Filed: 1983-10-04
Abstract: The invention relates to a process for the elimination of polluting organic substances from liquids, in particular waste waters, by adsorption to suitable adsorbents and for the regeneration of the adsorbents, which were used in the elimination of these polluting organic substances, by regeneration treatments conventional per se. The process according to the invention is to provide a technically simple manner as economical as possible for the purification of such waste waters and for the regeneration of the adsorbents used in this.   This is achieved in that, if required, to preseparate readily volatile organic substances, these are desorbed prior to the adsorption step using air or other gases and are adsorbed in a convention manner from the gas phase and contaminated zones, resulting from the type and concentration of different polluting organic substances, of the adsorbent used in a treatment column are either regenerated successively in layers in the treatment column containing the adsorbent or, following ejection from the treatment column, are externally regenerated.

Title: Circuit arrangement for reliably entering information into a computer
Inventor: KREHLE HANS-JUERGEN DIPL ING
IPC: G06F3/05
Filed: 1983-11-23
Abstract: A circuit arrangement is specified which ensures reliability in signalling terms with respect to addressing errors when entering information into a computer (R). Input channels (IK) of a multiplexer (MPX) via which the information which is to be entered into the computer is intended to pass into the computer are provided, by fixing one or more bits within their interface width, with a tag which is characteristic for each individual input channel and passes into the computer together with the information which is present on the respective input channel, via the multiplexer output (AK). In the computer, the respective characteristic tag is stored together with the channel address. All the information which is read into the computer is checked to determine whether it has the tag belonging to the output channel address. If this is not the case, then the information does not originate from the addressed input channel and is rejected. During cyclic interrogation of all the multiplexer channels, the channel tags are selected such that each bit location within the computer input interface (E) has a logic 0 and/or 1 at least once within each interrogation cycle. <IMAGE>
