Abstract: A method and apparatus for discriminating the data signal of a transmitter means. Binary encoded data is transmitted between a transmitter means and a receiver means in an amplitude modulated signal varying about a threshold level. A means and method are included for determining the number of threshold crossings of the carrier during each of a number of discrete successive time intervals. A further method and means characterizes those of said time intervals wherein the number of threshold crossings equals or exceeds a first predetermined number as a mark, and those of said time intervals wherein the number of threshold crossings does not exceed said predetermined number as a null. The number of successive marks not separated by a predetermined number of nulls is then counted by a further aspect of the method and means. A series of successive marks in excess of a second predetermined number is then characterized as a one, and a series of successive marks in a range below said second predetermined number is characterized as a zero. The signal transmitted by said transmitter means is discriminated from interference by spurious signals.

Abstract: In a process and device for treating polluted liquids, in particular effluent pollutant-containing, gas bubbles are produced by an electrolytic treatment in the liquid, and pollutant particles adhere to these gas bubbles and thus collect at the liquid surface being skimmed off. The device comprises a container (2) for the liquid and an electrolysis apparatus (38) through which the liquid flows, said electrolysis apparatus having an anode/cathode arrangement (54) and the electrolysis apparatus (38) being arranged inside the container (2) in such a manner that the liquid flowing into the electrolysis apparatus (38) through an inlet port (18) flows through vertically from bottom to top, that is in the upthrust direction of the gas bubbles formed. By this means, a particularly high efficiency is achieved during treatment. <IMAGE>

Abstract: Liquid, curable, unsaturated polyester resin compositions having improved inherent adhesion to the surface of their pre-cured composition after processing has been interrupted for an extended period. In order to enable damage-free extension of processing interruptions while simultaneously reducing the emission of styrene, the reactive compositions based on unsaturated, copolymerisable polyester resins, styrene, catalyst and reaction accelerator are treated with an additive combination comprising up to 2% by weight of an additive component A and up to 8% by weight of an additive component B, in each case based on the unsaturated copolymerisable polyester resin. A) here is a wax-like organic substance having a melting point of <90 DEG C, preferably <120 DEG C, and B) is a modified, liquid epoxy resin or a styrene-soluble polymer containing monomer units derived from vinyl esters or vinyl acetals and having a melting point of between 40 and 170 DEG C. The liquid, reactive compositions are used to produce thermoset mouldings or moulded parts or materials reinforced with glass fibres or mono- or polylaminated with glass fibres.

Abstract: The invention relates to a process and apparatus for cleaning a swimming pool, where the apparatus or device, moves back and forth in the swimming pool, and where the device has driving gears or belts that can be switched to drive reverse or forward during operation. A contact rail is frontally positioned in the cleaning casing of the device, and a swich rail is positioned at the rear of the casing. Correction-dependent signals are obtained by the device striking an obstacle and these signals are supplied to a gear via a control mechanism. Upon obtaining such signals, the driving gear or belt slows down and remains still for so long until the other driving gear or belt which is still moving turns the cleaning device around and until the rear switch rail is activated. The signals resulting from the switch rail are used for switching the gear to reverse and for straightening out the cleaning device to a new position and prepare it to a forwards motion to continue its course along the swimming pool.

Abstract: Broadband amplifiers which are intended to be linear suffer from distortion and although many techniques have been devised to overcome this problem significant improvements are required especially at frequencies above 100 MHz. An error signal is formed from the output of the amplifier 4 by comparison in a subtractor 11 with its input and the error signal is combined in a coupler 17 with the amplifier output to reduce distortion. The present invention provides automatic amplitude and phase control of the signals forming the error signal by means of components 24 and 25 in a multi-channel input and in the error signal by means of components 13 and 14. These components receive control signals from feedback networks 18' and 20' which each process two of three input signals from: couplers 34, 36 before the subtractor 11, a coupler 22 which passes the error signal and a coupler 21 after the coupler 17. Preferably the two input signals used by a feedback network are used to form in-phase and quadrature signals by a 90 DEG  phase shifter 41 and mixers 42 and 43. These signals are each amplified 46, 47 and integrated 48, 49 to provide the control signals. The input signals from the feedback networks may be reduced in frequency and applied to a DSP which then provides the control signals. <IMAGE>

Abstract: An electronic security system includes a controller for controlling access to a location through activation of a lock mechanism in response to coded data and command instructions read from a key or card containing an electronic memory. The key memory data includes information specific to the keyholder which is decoded and acted upon by the controller. The controller memory can be reduced in size while still allowing the use of a large number of keys, by distributing a larger amount of data to the key memories. The controller is also capable of writing and altering key memory data in real time to control the subsequent use of the key.

Abstract: A display system for two-dimensional displays wherein images are applied (e.g., photographically, printed or the like) to transparent sheets and transported through a viewing machine, the sheets being sequentially positioned in a back-lighted viewing window. The sheets are suspended from rods and stored behind the back-lighting area. The rods are arranged in a desired sequence in a storage rack having an entrance and exit. A chain is entrained on a circuitous pathway through the machine. The pathway starts at the exit end of the storage rack referred to as a pick-up station, then passes over the back-lighting area, extends downwardly between the back-lighted area and the window, passes under the back-lighting area and behind the stored display sheets to a return station that receives the sheets and directs them to the entrance to the storage rack, and then back to the pick-up station. The images are inverted on the sheets with the sheets suspended from the rods, e.g., in storage as they are inverted when positioned in the viewing window. As the sheets travel through the viewing window a guide channel lightly grips the sheets to keep the sheets taut for viewing.
