Abstract: A high frequency divider arrangement for use in transmission systems operating in the gigabit/second range. Known divider arrangements based on ECL logic families have an upper frequency limit which is too low for dividing signals in the gigabit/second range. In one embodiment the inputs of a high frequency multiplexer are connected respectively to the stages of a feedback shift register which produces a sequence of five code words which are serialized by a multiplexer. The bits in the serialized code words occur in blocks which define a mark/space ratio of the output signal which has a frequency of 2/5ths of the clock frequency applied to the multiplexer. By means of additional circuitry, for example D-type flip-flops, the output from the multiplexer can be divided further. The code word(s) applied to the multiplexer can be held static, changed each time the inputs of the multiplexer have been scanned, or held temporarily static for a predetermined number of scans and then changed.

Abstract: A laminate is formed by two or more foil webs 81, 82, 83 being laid together without a binder, surface against surface, following which the webs 81, 82, 83 laid together are subjected simultaneously to a pressing and a crosswise orienting within areas I, II, together forming a pattern of narrow, parallel lines, generally extending in the longitudinal direction of the webs. The simultaneous pressing and orienting are effected at a temperature which lies below the melting interval of the surfaces facing each other and are produced by impression from alternately either laminate side, while permanently or transiently imparting a zigzag or wave shaped cross section to the foils laid together 81, 82, 83. A device for working the method comprises means for feeding two or more foil webs 81, 82, 83 towards a crosswise stretching system Q, means for superimposing the foil webs 81, 82, 83 in the system, whereby the crosswise stretching system 2 comprises means 72 for providing pressure along lines generally extending in the longitudinal direction of the foils 81, 82, 83, and for simultaneously stretching the foils 81, 82, 83 in the crosswise direction for the formation of a laminate 79 having a configuration of generally longitudinal wrinkles, transiently and generally evenly distributed. <IMAGE>

Abstract: A system for detecting missing or superimposed sheets fed to a sheet processing machine uses a measuring device for generating a signal increasing with the number of superimposed sheets and an evaluating device for emitting an electrical signal when irregularities occur. A pulse transmitter is synchronized to the sheet feed mechanism and operates to emit an initial and final pulse timed to the sheet feed. Electronic storage is reset upon the initial pulse, and operates to integrate values of the measured signal until the final pulse is received. Upon receipt of the final pulse, the stored value is compared to a reference value to detect any irregularities. Preferably a microcomputer is used for signal processing.

Abstract: The present invention relates to a process for the preparation of plasticizers for rubber compounds, as well as for the preparation of a fuel oil. In this process, a hydrocarbon solvent is heated, after which both vulcanized rubber waste and unvulcanized rubber waste are added to the hot hydrocarbon solvent, with energetic stirring. The waste rubber is then decomposed under a pressure of between 5 x 10<2> and 25 x 20<5> N/m<2>, while the hydrocarbon solvent is continuously recirculated through the reaction mixture. The final product is separated off from the resulting suspension by distillation at a temperature of 200-560 degrees C and a pressure of 10 - 2 x 10 <5> N/m <2> in the presence of an inert gas.

Abstract: A flame retardant formulation for application as an aqueous working dispersion onto surfaces of normally combustible materials. Upon exposure to elevated temperatures and/or flame, the formulation creates a substantially continuous protective film as it undergoes a transition of composition, with the protective film generally encapsulating and/or enveloping the surface of the article onto which it is applied. In addition to being insulative, the film excludes oxygen from the surface of the substrate, and is capable of radiating infrared and visible light when exposed to elevated temperatures. In the formulation, and upon exposure to elevated temperatures and/or flame, the material releases forms of chlorine, bromine, and phosphorus, for the protection that these materials provide. In addition, antimony oxide is present for its protective property, together with hydrated alumina for its water-release capability.
