Abstract: Arrangement for treating the pass line height variations in a continuous rolling mill having a plurality of stands between which loop lifters are arranged whose lifter arm fixes an angle  alpha between pass line parallel and arm axis, and for correcting strip feed and/or tension within the rolled strip in the event of a variation of the pass line height D, comprising the following elements: a) an adder circuit (34), by means of which the diameters of the back-up and work rolls (5,6;7,8) and further addable quantities influencing the pass line height D can be added to give an electrical analog value UD corresponding to the pass line height, b) two function generators (42, 43) which are downstream of the adder circuit and process an electrical quantity U alpha  and UD proportional to the angle  alpha , taking as a basis the functional relationships:         U1 = f1 (U alpha , UD)  and         UM/Z = f2 (U alpha , UD) to give a signal in each case, the signals generated by the function generator being input, with conventional matching, to control circuits for controlling the roll speed and the drive of the loop lifter arm (in the equations:  U1 = analog electrical quantity with respect to the strip feed; UM/Z = analog electrical quantity with respect to the strip tension factor). The arrangement thus makes it possible to keep the tension Z automatically constant when the pass line height D changes. <IMAGE>

Abstract: Fully cured reinforced molded resins such as polyester, polyurea-urethane, polyurea, polyurethane, polyisocyanurate, polyepoxy and polycarbonate resins can be in-mold coated to cover surface defects such as sink marks and microcracks with an improved coating composition comprising 5-94% by weight of an ethylenically unsaturated base resin free of groups reactive with isocyanate radicals; 5-94% by weight of an ethylenically unsaturated monomer free of groups reactive with isocyanate radicals; and 1-20% by weight of isocyanate-containing compounds or compounds which decompose to form free isocyanate-containing compounds. Such coatings unexpectedly have improved adherence to molded articles over those obtained from similar compositions which contain no free isocyanate. The compositions may contain minor amounts of emulsifiers, fillers, catalysts, cross-linking agents, dryers and pigments. In particular, the coatings obtained when the compositions contain electroconductive fillers can be painted by standard electrostatic paint techniques.

Abstract: In the batchwise production of asphalt concrete only such aggregate is utilized, as comprises a coarse-grained portion, a fine-grained portion and a filler portion. The coarse-grained portion and the bituminous binder used are mixed in a mixer, and the filler portion is added to the mixer In such a way that it is has been taken up by and suspended in the binder film deposited on the coarse-grained portion before the free particles of the fine-grained portion are added. In such a way the thickness of the binder film and the capability thereof to take up the particles of the fine-grained portion are increased so that also said particles are coated with and suspended in the binder. 
     An apparatus for carrying the production process into effect has a control device (30) to ensure that the binder film deposited on the particles of the coarse-grained portion has taken up the particles of the filler portion and has thereby obtained the desired thickness and viscosity before the free particles of the fine-grained portion are supplied.

Abstract: Photo-optical switch apparatus useful for example in keyboard switches includes a photopolymerized orthogonal matrix of horizontal and vertical intersecting light channels or guides, monolithically formed by exposure to ultraviolet light on a flat planar, plastic substrate. Each intersection has a refractive index higher than either the channel or the adjacent substrate area. A curved tap or light coupler couples the horizontal to the vertical channel of the array. The intersections of the channels are disposed over an array of upstanding projections on a flat mounting substrate with each projection located at a respective intersection of the horizontal and vertical light channel. A light absorbing key pad is arranged over each intersection to couple light from the channel up into the key pad. A relative loss of light indicates the key being depressed.

Abstract: An array (48, 49, 50, 51 ) of fiber optic couplers coupling an input (45) and an output (46) waveguide. The output waveguide (46) is routed among the couplers of the array such that either backward or forward coupling exists. With backward coupling, energy coupled into the output waveguide (46) in a coupler of the array is guided back to the preceding coupler for coupling back into the input waveguide (45). 
     The backward coupling allows recirculations to occur between couplers to create poles and zeroes in the transfer function of the array which transfer function can be programmed or tailored somewhat to have specific characteristics. 
     Further, the backward coupling allows the array to be used for matrix-vector multiplication.

Abstract: A filter, such as a bandpass filter for use at intermediate frequencies in a radio transmission system, includes at least one filter stage comprising a common-emitter transistor (1) having resonant circuits (4, 5) in both its collector and emitter circuits. The ratio of the impedances of the resonant circuits (4, 5) determines the frequency response of the filter.

The presence of the transistor (1) also enables the input return loss of the filter to be determined independently of the tuning of the resonant circuits (4, 5). Individual filter stages can be cascaded.
