摘要:
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.The gases formed during the fermentation process in the tank can either be used in the installation as process energy or can be supplied via a line to another energy supply plant.
摘要:
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.

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.

A flank protection for the protection of passengers from impacts of lateral areas of motor vehicles comprises a vehicle body side wall having a window, such as a door, wherein reinforcement for preventing excessive penetration of the vehicle by other vehicles is located solely in lower areas of the side wall, particularly in an outer body part, while an upper side wall portion is formed of inner and outer body parts, preferably above a belt line of the vehicle, are composed of resilient portions that are yieldable to the absorption of outwardly directed reaction forces applied by an occupant against said body parts above said belt line.

A method and a voice conference system for carrying out a voice conference are disclosed, the system having at least three voice terminals in a communication system. At least one of the voice terminals is associated with a first group such that the voice data provided by the respective receiving channels thereof is decoded into individual voice signals for said group. Said individual voice signals are superimposed to form an aggregate voice signal and the aggregate voice signal is encoded into first aggregate voice data. Furthermore, at least two of the voice terminals are associated with a second group such that the second group has only voice terminals wherein an extensive inactivity on the respective receiving channels thereof is identified. The first aggregate voice data is supplied to the voice terminals associated with the second group by the respective receiving channels for a respective output of the first aggregate voice data.
摘要:
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.

The specification describes a cardiac frequency measuring instrument which has a frequency measuring device to be carried on the arm of a user. A cable connects the measuring instrument with measuring electrodes carried on the body and with an optical display for the measured heart frequency. There is a miniaturized digital circuit accommodated in the housing having the size of a wrist watch with a minimum electrical power* for the digital measurement and display of the cardiac frequency. Use is made of a resonant amplifier, connected as a high pass filter, for suppressing the amplification and display of motional artefacts.*consumption or dissipation
摘要:
A perforated drum drier with a first lower inlet opening in a rear wall of a drier housing for feeding a tubular knit fabric to a first drum in the housing, and with a substantially horizontal stentering chain mechanism extending through a second upper inlet opening into the housing to a front guide roller for the two pin-studded stentering chains, the axis of which is located slightly ahead of a vertical plane extending through the axis of the first drum, and so far above the first drum that the parts of the lower stringers of the chains adjacent to the front guide roller are substantially in horizontal alignment with the top of the first drum so that an open fabric will be removed from the pins of the chains by its own gravity and by the suction of the first drum and be transferred simultaneously to this drum. The stentering mechanism is located so highly from the floor that an operator can stand underneath it.
