Abstract: A seal ring has a reinforcing ring with an inwardly-directed conical extension and a lip ring having elastic properties which embraces said extension in the manner of a U for a relatively-rotatable seal and bears on the shaft to be sealed as a static seal. The lip ring is a length of hose enlarged on one side to form an outwardly-directed flange. The hose portion of the lip ring is inserted into the extension of the reinforcing ring in the direction of its conical narrowing with the resulting elastic deformation at the flange tipping up the hose portion to form the U.

Abstract: The present invention relates to the simultaneous shaping and lamination of lightweight laminated transparencies, particularly those that are suitable for use in aircraft. The plies of an assembly to be shaped and laminated are assembled with additional elements to form a flexible cell of air impervious material. The cell includes an air impervious flexible wall defining a peripheral space around the assembly and porous-material in the space. The cell containing the assembly is mounted over a vacuum mold and heated to sag the cell and its assembly to the contour of the mold while evacuating the cell while the cell and said assembly are exposed to atmospheric pressure. 
     The cell is cooled while still under evacuation until the shape of the assembly is set, then is separated from the vacuum mold. The resultina assemblv thus shaoed and laminated is separated from the cell.

Abstract: A fuel injection system, especially for air-compressing, spontaneous ignition reciprocating piston internal combustion engines. At least one parameter which characterizes the injection process, such as beginning and duration of the injection, is adapted to be regulated by at least one electromagnetic control valve per cylinder unit which can be controlled by an electrically operating data processor as a function of characteristic operating parameters of the internal combustion engine. In order to compensate for transmission deviations of the electromagnetic control valves caused by wear and operation, the control pulses of the data processor are transmitted to each electromagnetic control valve via a suitable circuit in such a way that the control valve opens and/or closes with a constant time delay during each control procedure. The constant time delay of the control valve can be established as a function of the actual speed of the internal combustion engine. The control time point of the control valve, as determined by the data processor, for opening and/or closing the control valve can be varied as a function of the constant time delay thereof.

Title: Extrusion die for the production of flat profiles from several rubber or plastics compositions
Inventor: SIEVERS WILLI DIPL-ING
IPC: B29C48/08
Filed: 1984-05-19
Abstract: An extruder head for producing flat cohesive profiled strips from resilient mixtures of differing composition, such as mixtures of rubber or synthetic material, and especially for manufacturing uncured tread strips for pneumatic tires having a two-ply central portion and two similar edge portions. The extruder head includes two extruders which are disposed at an acute angle next to or above one another, and feed a common extrusion nozzle via a preform die or member having flow channel which extend one above the other. The extruder head also has a third extruder which conveys the mixture for the edge portions and is connected to the preform die at a greater angle than are the aforementioned extruders. The flow route of the third extruder in the preform die, starting from its connecting bore, is initially guided as a single connecting channel to a direction-changing angle piece in the central region above or below the flow channels associated with the other two extruders, and from there is split into two branch channels which span the connecting channels, are essentially of equal length, and in their edge regions end in edge channels which lead into the edge portions of the profiled strip.

Abstract: Apparatus using reflected ultrasonic waves for discriminating a characteristic property of a medium (e.g. tissue) to be observed is provided. The apparatus obtains information from the reflected waves concerning the nature of fine structure of the medium. More practically the interval between small reflecting bodies dispersely distributed in the medium is determined as a characterising parameter. In practice the small reflecting bodies are distributed at a variety of intervals in the medium. The apparatus provides a means for calculating an average value of the intervals and/or an indication of the amount of variation or fluctuation of the intervals and for displaying the result of calculation. The apparatus may use the cepstrum of a receiving signal corresponding to the reflected ultrasonic wave, or may use self-correlation of the receiving signal to obtain an average value of the intervals.

Abstract: In a method for measuring and controlling the level of molten metal in a casting mould, guide channel or the like, the size of eddy currents induced in the molten metal by means of a measuring coil is measured, which is a measure of the distance from measuring coil to molten metal. In this process, the eddy currents are induced on the surface of the molten metal, their size is compared with a nominal value and the inflow rate of molten metal controlled according to the difference. An apparatus intended for this makes provision for the measuring coil (20) to be arranged above the molten metal and to be connected to an electronic unit (28), which supplies the measuring coil (20) with the alternating current required to produce the eddy currents and measures the size of the eddy currents, and for the electronic unit (28) to be coupled to a control device (9) in order to compare the measured actual values of the size of the eddy currents with a nominal value, which control device drives a unit (11) for measuring the flow rate of molten metal through an outlet pipe (2) or the like.   <IMAGE>
