Patent DE-3144362-A1 (DE)
Title: Actuator which can be operated electromagnetically
Inventor: FEDER MEINRAD
IPC: F15B13/044
Filed: 1981-11-07
Abstract: The actuator according to Figure 1, which can be operated electromagnetically, has a disc-shaped armature (19) which is operatively connected to a control slide valve (26). The armature (19) is located in the housing (13) of the electromagnet, which housing (13) is filled with the pressure medium via a hole (36) which is connected to the return (33). Said pressure medium originates from a pressure medium source (44) which produces a connection to the load or to the return depending on the position of the control slide valve (26). Since the internal space (13') of the housing (13) is filled with pressure medium and the armature forms an annular gap (S) opposite the housing internal space, vibrations occurring on the control slide valve (26) can be damped immediately. <IMAGE>

Title: Method for displaying ultrasound echo signals and device to carry out this method
Inventor: HOELZLER GEORG DIPL ING
IPC: G01S7/52
Filed: 1982-11-02
Abstract: Ultrasound echo signals which are obtained by means of a sector scanner are recorded as lines of a sector peak (SP) radially in the direction of a sector arc (SB) on the monitor of an ultrasound device. On the basis of the radial formation of the lines, the mean surface luminance (LF) occurring with a specific defined background brightness of the lines decreases in existing display methods in the direction of the sector arc (radiation law LF SIMILAR 1/R, where R is the sector radius). According to the invention, the lines to be displayed which radiate from the sector peak (SP) are systematically superimposed in a defined radial area up to the total predetermined number of lines in such a way that the mean surface luminance remains largely constant within this radial area (R); the selected lines are superimposed continuously from the dark value to the light value. <IMAGE>

Title: Method for measuring pitch and tooth thickness on toothed test objects
Inventor: PRIPLATA HEINZ DIPL ING
IPC: G01B7/28
Filed: 1982-12-03
Abstract: The invention relates to a method for measuring pitch and tooth thickness on toothed test objects, in particular gearwheels. The test object is touched in an initial position by two probes which are connected to measuring sensors. The measurement signals are fed to a computer. The test object is turned further with the probes in contact, the signals produced by the measuring sensors in the process being fed to the computer. The computer determines the scanning characteristics of each tooth profile and, if necessary, the associated mean straight lines. The measurement values which are distributed in conjunction with further division of the test object on the characteristics or mean straight lines are transformed to the initial measured values obtained at the start of measurement, and from this the computer determines by an averaging operation an error-free mean value and the toothing parameters.

Title: Frequency-sensitive phase-locked loop
Inventor: MUELLER MARTIN DIPL ING
IPC: H04L7/033
Filed: 1982-12-08
Abstract: For clock synchronisation to the bit rate of a binary data signal having a random character, a simple circuit is indicated for a phase discriminator which first derives two clock signals, phase-shifted through 90 DEG , from the signal of the voltage-controlled oscillator (VCO) in a branch (VC) and then carries away these two clock signals via bistable circuits (FF1, FF2) which are sampled by a pulse string (DS) derived from the pulse edges of the data signal. To obtain the control signal, the output signals of the bistable circuits obtained in this way are then evaluated in a circuit comprising AND elements (V1, V2) and a further bistable circuit (FF3) in order to derive a pulse-shaped control signal. <IMAGE>

Patent DE-3304491-A1 (DE)
Title: Method for producing ultrafine staple fibres and device for practising the method
Inventor: HENSEN FRIEDHELM DR ING
IPC: D01F8/04
Filed: 1983-02-10
Abstract: A manufacturing method for producing ultrafine staple fibres from highly polymeric chemical materials is described. According to the invention, two or more polymers which are not chemically substantive are melted in a melt spinning process and dispersed in one another in suitable amounts in order that they can then be spun by means of single component spinnerets to give matrix filaments, which are cooled and stretched. In a subsequent treatment step, the tows formed are converted on a breaking converter, in particular a short staple machine, to slubbing which contains staple fibres having titres of preferably 0.01 to 1.7 dtex and fibre lengths of 25 to 60 mm. In the treatment of the continuous filament on the breaking converter, the matrix filaments are loaded to breaking point by elongation. Owing to the different elongation behaviour of the individual polymer components, separation of the structures present occurs and the bi- or multicomponent fibres split into fine individual fibres, since the adhesion of the filaments in the matrix is low because of their low wettability at the phase interfaces and the polymers are selected, inter alia, using this criterion. Special features of the spinning device and the products produced and their properties are additionally described.
