Abstract: A layered push button switch has a base layer 1, an upper layer 2 and a spacer layer 3 forming a switch chamber 4. In order to be able to close two circuits simultaneously with one key operation, without any additional movement, conductor end strips 6 to 11, of two circuits, run parallel to one another in a central region of the switch chamber 4 such that the overall width of the parallel arrangement is significantly less than the diameter of the switch chamber 4. In addition, two contact surfaces 14, 15 are provided which in each case cover only the conductor end strips of one of the circuits. <IMAGE>

Abstract: Die Erfindung bezieht sich auf eine Vorrichtung zum schwebenden Führen von Materialbahnen mittels eines gasförmigen oder flüssigen Mediums. Die Vorrichtung besteht aus mindestens einem länglichen Strömungskörper mit auf der Warenbahnoberseite konvex gekrümmter Oberfläche, und an beiden Längsrändern in Reihe und quer zur Materialbahnlaufrichtung angeordneten Düsen 4a, 4b, mit denen zwischen den Strömungskörper 2 und die Materialbahn 1 das gasförmige oder flüssige Medium einblasbar ist. Die dem einen Längsrand des Strömungskörpers 2 zugeordneten Düsen 4a sind gegenüber den dem anderen Längsrand zugeordneten Düsen 4b in Richtung der Längsachse des Düsenkörpers 2 um eine halbe Teilung versetzt. Die Düsen 4a, 4b sind als mit Abstand von dem Strömungskörper 2 angeordnete Freistrahldüsen ausgebildet und sind mit spitzem Winkel flach in den Spalt zwischen der Materialbahn und dem Strömungskörper 2 derart gerichtet, daß die einander benachbarten Ränder der entgegengesetzt gerichteten divergierenden Strömungsstrahlen bei fehlender Materialbahn 1 im wesentlichen ohne gegenseitige Behinderung aneinander vorbeiströmen und mit kleiner werdendem Abstand der Materialbahn 1 von der Oberfläche des Strömungskörpers 2 mehr und mehr aufeinandertreffen. Die Vorrichtung arbeitet damit in Abhängigkeit von dem Materialbahnabstand sowohl nach dem Tragflächenprinzip als such dem Luftkissenprinzip mit fließendem Übergang von dem einen in das andere Prinzip. Die Kennlinie für die materialbahnabstandsabhängige Tragkraft verläuft steil bis zue Tragkraft Null and hat bei geringem Abstand einen sehr großen absoluten Wert.

Abstract: The stages of the method which are to be carried out manually are extremely simplified and the degree of utilisation of the blank prior to cutting can be determined objectively and weighed up against the subjective feeling of the suitable selection of the structure. When cutting patterned materials, it is also guaranteed that the pattern on the part to be cut out has been selected in a simple manner in such a way that, in the finished part, for example an item of clothing, a uniform transition is ensured between the different individual parts.

Abstract: A process and apparatus for making hot-rolled steel strip from a striplike continuously cast starting material uses successive processing steps in which the striplike cast starting material after solidification is brought to the hot rolling temperature and fed to a multi-stand rolling mill for rolling to the finished rolled product. A continuous casting unit supplies the multi-stand rolling mill. The rolling to the finished rolled product occurs continuously in three or four roll stands to achieve the largest possible reduction per pass. The first two roll stands operate with an approximately maximum rolling moment and a large working roll diameter.

Abstract: In the droplet size measuring apparatus of the forward scattering method, particles (6) to be measured in a scattering zone (A) having a predetermined scattering path length (L) are irradiated with parallel laser beams. The irradiated beams are scattered by the particles (6) and the scattering beams are detected by the photodetectors (8-1 - 8-K) arranged at predetermined scattering angles (θ 1 --θ K ). The output of the photodetectors (8-1 -8-K) are input to the arithmetic operating unit (11), thus the intensity distribution I(θ) of the scattered beams is measured. The droplet size distribution n(D) is calculated from the intensity distribution I(θ) using the following equation:

Abstract: Advantageous neural network realizations are achieved by employing only negative gain amplifiers (100) and a clipped T matrix (20) having conductances T ij  which have only two values. Preferably, one of these values is a preselected value set by the value of a fixed resistor, and the other value is zero, created simply with an open circuit. Values for the T ij  terms of the clipped T matrix are obtained through an iterative process which operates on the clipped and nonclipped matrices and minimizes the error resulting from the use of the clipped T matrix.

Preferably, the wire guide is flexible and steerable for precise placement. The wire guide includes an elongated wire member having a Doppler crystal attached in longitudinal alignment at its distal end. Electrical leads extend from the Doppler crystal along the wire member to the approp­riate test equipment for measuring the fluid flow velocity in the region of the Doppler crystal. Preferred embodiments of the Doppler means include piezoelectric crystals and piezoelectric polymers. Also disclosed is a guide wire with a laser Doppler means.

Abstract: A gripping device for an apparatus for placing electronic and/or electrical components on a substrate comprises a pair of grippers (1 and 2) which are movable relative to one another by compressed-air or vacuum operated means to close and open the jaws (4 and 5) of the grippers. For indicating the absence of a component between the gripper jaws when the jaws are closed, an orifice (11) is provided which communicates with a source of compressed air or vacuum at least during the closing movement of the jaws so that air flows through the orifice during this movement. If the jaws are closed to less than a predetermined distance between them which is equal to the width of the smallest component to be handled by the gripping device, the orifice is closed by one (1) of the grippers to interrupt the flow of air through the orifice, and means responsive to the interruption produce a signal to indicate this closure of the gripper jaws. The orifice is formed in a body (6) which is fixed in relation to the movements of the grippers and which is formed on two opposite sides with abutment surfaces (7 and 8) which limit the closing movement of the grippers and in one (7) of which the orifice is formed.

Abstract: This invention is concerned with materials for nonlinear optical devices for the conversion of optical energy at one frequency to optical energy at another frequency. 
     Laser techniques have been developed to a great extent and it is possible to obtain various kinds of laser light by utilizing solid, gas, and liquid media. Laser light having various wavelengths is often desired and in some cases, a laser light exhibiting a continuous spectrum over a certain range of wavelengths is desired. One means for converting coherent laser light of a fundamental frequency into laser light of a wavelength having a frequency twice the fundamental frequency (i.e., the second harmonic) involves passing the laser light through a nonlinear optical crystal. 
     This invention involves devices for and method of generating coherent second harmonic light radiation. The devices comprise a laser source of coherent light radiation at a fixed fundamental frequency, crystalline 5-chloro-2-nitroaniline that crystallizes in a non-centrosymmetric configuration, means for directing the output radiation of the laser onto the 5-chloro-2-nitroaniline, and output means for utilizing the second harmonic frequency.

Abstract: The present invention provides a high speed low power electrical circuit for converting true TTL level signals to true ECL level signals. The circuit only has a single buffer delay with some small addi­tional delay due to an input emitter follower stage. The circuit includes a clamped, switched emitter fol­lower (R1, Q1, Q2, Q3) which acts as a level shifting comparator; a selfcentering reference threshold translator (Q7, Q8, Q10, Q15, R5, R6, R12); a clamped level shifted input translator (Q4, Q5, Q14, R3, R4, R10); and, an ECL Buffer Driver (Q11, Q12, Q13, R7, R8, R11). The circuit also includes a TTL reference (D2, Q6, Q9, R2) and an ECL reference (Q7, Q8, R5, R6) which are tied together. If the TTL reference level shifts slightly due to temperature changes, supply voltage shifts or other factors. the ECL voltage refer­ence will automatically shift by an appropriate per­centage to compensate for the original shift in the TTL reference.
