Abstract: The invention relates to a radial bearing which can be used for bearing problems in which an angular displacement occurs during operation by virtue of the elastically flexible shaping of a bearing sleeve on which an elastically flexible bearing element with an essentially matrix-type fibrous structure is arranged.

Abstract: A sachet-shaped tear-open package for rapid access to a packaged product, having at least one sealed seam with a weakening in the form of a notch or groove as a tearing aid, whereby the weakening has an additional gripping and opening aid in the form of at least one punch-out, aperture, embodied next to the weakening, is characterized in that a rim of the punch-out has an at least partially serrated contour.

Abstract: An oscillator circuit is provided for stabilizing the amplitude of a HF oscillation of an audio signal. In such an oscillator circuit, an audio signal having a frequency in the range of 20 Hz . . . 20 kHz is coupled into the oscillator circuit, is modulated with a high frequency and is emitted in the form of an RF audio signal having a frequency of more than 2 MHz. Such an oscillator circuit is used for instance in an infrared transmitting unit, wherein a low frequency audio signal is transformed into a higher frequency infrared signal. The higher frequency audio signals are transmitted via infrared channel to an appropriate receiving unit--for instance to infrared head phones--which comprises a receiving unit having an appropriate demodulator and preferably also a stereo-decoder in order to reproduce the low frequency audio signals.

Abstract: Electronic clocks with analog time displays and a vibrating quartz crystal (1) as a time standard, as well as electronic frequency dividers (6, 7). The display elements are driven by an electronically controlled motor (SM), said motor comprising a power winding (87) and a control winding (68). The control and regulating circuit for the electronically controlled motor (SM) is so designed that only one rpm above the rated rpm is controllably adjustable and, when the frequency of the clock varies, correcting signals are supplied to the AC drive pulses in power winding (87) through a bistable flip-flop (50), said flip-flop being subjected to real pulses derived from frequency dividers (6,7) and pulses derived from motor (SM), a NOR element (58) connected to the output of flip-flop (50) and an additional frequency divider (59), a field effect transistor (88), and a resistor (89).

Abstract: A strip-type door having a plurality of individual strips arranged in overlapped relationship one to another comprises a series of swingable supports on which the individual strips are vertically suspended when the latter take a vertical position. A mounting element connected to a lintel over the door opening has a mounting portion, a supporting bar and an arcuate wall defining an arcuate channel. Each of the supports is formed with a curved portion insertable into the channel in the mounting element to form with this wall a hinge about which the supports carrying the individual strips can swing relative to the mounting element between a plurality of positions. The curved end portion may be inserted into said channel in only one of these positions so that the inadvertent falling or removal of the supports out of the channel when the strips are in their working swingable positions is prevented.

Abstract: An echo-sounding receiver circuit comprising first and second receiver channels and an AND gate enabled by simultaneous outputs from both receiver channels is disclosed. The first receiver channel includes an echo stacking circuit, an echo selection circuit, and a tracking window circuit for establishing a measuring range or window whose timing is determined in part by detection of the first primary target echo in a sounding period and whose duration is established by the tracking window circuit. The second receiver channel includes a tracking threshold circuit and a second echo selection circuit for detecting the first echo that exceeds an amplitude determined by the amplitude of the preceding primary target echo. Upon detection of a primary echo by the second channel during the window established by the first channel, the AND gate supplies an output signal to a recording instrument or other utilization device.

Abstract: A profiled outer sole for shoes, especially sport shoes, made in a mold and consisting of rubber or other material having rubber-elastic properties, which is provided with profiled projections laterally delimiting the tread surface of the outer sole; the profiled projections, in turn, are provided with groove-shaped slots extending obliquely to the respective tangential plane tangential to the outer boundary surfaces of the individual profiled projections within the bisecting plane thereof.

Abstract: A profiled outer sole for shoes made of a material having rubber-elastic properties with the sole including a tread surface having a front tread end portion, rear tread end portion, a profiled middle area and profiled marginal areas arranged on respective sides of the middle area. The front tread end portion, the rear tread end portion and each of the marginal areas include outer edges adjoining the tread surface to a shell rim of the outer sole with each of the outer edges being rounded with a predetermined radius. The marginal areas define foundation strips having spaced block-shaped profiled projections enclosing box-shaped profiled projections with a number of groove-shaped slots being substantially uniformly distributed along each of the foundation strips.

Abstract: Hydrophilic polyolefin fibers containing inorganic pigments are obtained by means of flash evaporation of a superheated suspension, which is under at least autogenous pressure. The suspension comprises a dispersion of a hydrophobized inorganic pigment in an emulsion prepared from a solution of a polyolefin in an easily boiling solvent and an aqueous solution of a hydrophilizing agent. The suspension is passed through a nozzle into a low pressure zone to form pigmented fibers.
