Abstract: A removable rear seat for motor vehicles, in particular for Estate cars with a variable-volume loading space, having a rigid seat bench and a seat-bench substructure for fixing the seat height. The substructure is fixed on the floor of the vehicle body via releasable anchorage locations. In order to provide a rear seat which is manageable, easy to remove, and makes optimum use of the resulting free space after the rear seat has been removed, the seat-bench substructure is connected releasably, at its end remote from the anchorage locations, to the seat bench and is retained in its anchorage location. Thus, it can be pivoted out of a use position into a stowage position on or in the floor of the vehicle body and vice versa. At least one manually actuatable locking device locks the seat-bench substructure in its use position and determines the seat height.

Abstract: Controlling a fermentation plant working with a horizontal fermentor which operates per the regenerative flow process is particularly difficult, if there is a high proportion of dry substance. Biogenic decomposition in the fermentor was thus far influenced merely by recycling a portion of the ferment from the outlet to the fermentor entrance. According to the invention, the process of control is enhanced by the measurement of the pH and the dry substance portion at various points in the fermentor and controlling the fermentor on the basis of these measurements in such a way that the measurement data lie within certain established ranges. It is additionally possible, moreover, to adjust the pH and the portion of dry substance in the fermentor by the introduction of press water laden with methanobacteria from the ferment at inoculation points in the fermentor.

Abstract: An unwinding machine for wound rolls, e.g. of paper, has holders which can be swung alternately into the unwinding and the splicing positions. A new roll in the splicing position has its leading end engaged by a groove roller which draws the new web between itself and the old web during continued unwinding thereof and a blade roller is pressed against the groove roller to cut through both webs and attach an adhesive strip across the trailing end of the old web and the leading edge of the new web. The residue of the old web continues to be wound up on the blade roller while a small residue of the new web is picked up by the groove roller and carried away.

Abstract: A process and an installation for utilizing organic substances are proposed, in which the substances are correspondingly comminuted and processed by mixing and reaction stages to utilizable compost.The installation essentially comprises a heatable fermenter with a stirrer located therein. In order to obtain an approximately closed process circuit the comminuted substances are supplied as so-called fresh material by a supply shaft to a conveying shaft constructed as a heat exchanger and undergo corresponding heating therein. Through further supply of fresh material the already heated fresh material is supplied to the fermenter and mixed therein by the stirrer accompanied by further heating.The fermented matter formed in the fermenter, on supplying further fresh material, can be admixed in a specific ratio as so-called bacterial inoculum with the fresh material throughout the process circuit.

Abstract: A self-adhesive conductive elastic gel which is obtained by polymerization of skin-tolerable polymers or copolymers producing acrylic acid group containing monomers or monomer mixtures in an electrolyte-containing solution of a skin-tolerable starch material. This gel is primarily introduced into body electrodes as the skin-contacting conductive material and is better than known gels in that it provides a better adhesive effect upon reproducible use.

Abstract: A body electrode comprising one or more galvanically active sensors, a first layer capable of adhering to the skin on the body contact side and a non-adhesive covering second layer on the side of said sensors opposite the body contact side. The first layer comprises an electrically conducting adherent, elastic hydrophilic material. The body electrode is characterized by the fact that the first layer and the second layer have been produced by mold casting. The chief advantage of such electrodes is the fact that they may be produced by casting in a simple and cost-effective manner, thus avoiding stamping processess.

Abstract: A process for manufacturing a body electrode is provided. The body electrode includes one or more galvanically active sensors which are combined with a first layer capable of adhering to the skin on the body contact side of said sensors and a second layer on the side of said sensors opposite the body contact side. The first layer comprises an electrically conductive, adherent, elastic hydrophilic material. The second layer is a covering or supporting layer and comprises an elastic non-adherent material. According to the present invention, the layer adhering to the skin and the covering or supporting layer are cast in a mold during manufacture of the electrode. This process eliminates the problems encountered with the prior art stamping process, especially in stamping the conductive layer which adheres to the skin.

Abstract: A bioelectrical electrode is disclosed consisting of metal on its skin-side contact surface and having a conductive adhesive layer covering at least part of the skin-side contact surface. The conductive adhesive layer is formed as a layer of an aqueous dispersion adhesive that is pressure-sensitive and contains a substance that dissociates in aqueous solution. The preferred adhesive layer comprises an aqueous dispersion of a thermoplastic acrylic resin and gelatin. The preferred dissociating substance is MgCl.sub.2 and the preferred metal contact surface is zinc. The adhesive layer may additionally contain citric acid.

Abstract: A blood pressure measuring appliance having a pulse beat detector responding to arterial pulse beats, an ECG signal detector and a time measuring apparatus which ascertains the time intervals between peaks of a predetermined type of the ECG signal detected by the ECG signal detector, preferably its R-peaks, and pulse beats in each case following the R-peaks and detected by the pulse beat detector. A display apparatus displays a datum representing the duration of the ascertained time intervals as blood pressure information. The blood pressure measuring appliance must merely be calibrated initially, for example, with the aid of a sphygmomanometer, in blood pressure values. The inflatable bag can be eliminated for further blood pressure measurements.

Abstract: A pump for feed-pumps of fuel injection systems for internal combustion engines having a manually actuatable element, which operates counter to the force of a restoring spring to effect an inward stroke of a piston which includes a valve tappet thereon that pushes open a ball valve to the fuel feeding system of a feed pump. In operation, a medium is positively displaced from a work chamber into the feeding system. Upon an automatic return stroke of the piston, a medium is aspirated from the fuel feeding system of the feed pump into the work cylinder and at the end of the return stroke the ball valve closes automatically. In its position of repose, the pump does not require its piston to be locked in place, and pressure impacts of the feed pump are prevented from reaching the piston.

Abstract: In tunnel construction with shield drive locational concrete is brought in stages directly behind the shield as tunnel lining. In order not to have to interrupt the shield progress during concreting it is proposed to provide a shield tail element consisting of a plurality of lamina movable relative to the shield, in addition to a shield tail element attached rigidly to the shield. This basically stands still during the continuous progress of the shield and is drawn forward into the shield by lamina only during the segment concreting, in order to remain immobile there relative to the earth until the next concreting stage.
