Patent AT-E126957-T1 (AT)
Inventor: SENDELWECK GENE KARL

Abstract: This invention relates generally to the field of circuits for controlling the beam currents conducted in cathode ray tubes in television receivers, with important use for preventing warping or blistering of the shadow mask used in conjunction with cathode ray tubes for color television receivers, due to heating from localized and intense peak beam currents. An anti-blister circuit comprises a first detector (Q1,R1,R2,R3) for detecting amplitude excursions of a signal with luminance information beyond a white level threshold during each horizontal scan. This enables the circuit to be more sensitive by responding to excursions occurring during each horizontal scanning line. A first timer (C1,R5), responsive to the first detector, provides a first control signal related to a minimum duration of each amplitude excursion of the signal beyond the threshold. This enables the circuit to avoid controlling beam current, for example by reducing contrast, responsive to signal peaks which are too short to cause blistering or warping. Finally, a switch (Q2) and second timer (C2,R6), responsive to the first control signal, provide a second control signal which falls at a first rate to reduce beam current, for example by reducing contrast, during each minimum duration amplitude excursion; and, which rises at a second rate to permit the beam current to increase after termination of the amplitude excursion, until the next minimum duration excursion. The time constant for the second rate is much greater than the time constant of the first rate.

Abstract: Microcapsule formulations are combined with emulsions or particle dispersions in a single-package formulation which is storage-stable and provides substantially the full efficacy of each of the two forms as if applied individually. The single-package formulation is suspension having two dispersed phases-the first being an active species encapsulated in a shell of inert polymeric diffusion-limiting material (i.e., a microcapsule), and the second being an active species in water-insoluble form with no diffusion-limiting barrier at its surface. An appropriate suspension system is included to prevent the dispersed phases from agglomerating within themselves and with each other. The invention is useful in combining two different active ingredients as well as in combining immediate-delivery and delayed-delivery forms of the same active ingredient. The invention may for example involve combining a biocide with an activity modifier such as a safener, with the effect of lowering the needed amount of one or the other by removing it to a separate phase. In certain cases, a unique combination of surface-active agents maintains the phases in suspension.

Abstract: A valveless, positive displacement metering pump is provided which is capable of either mixing two or more fluids or dividing a fluid from an inflow line into two or more outflow lines. The pump includes a housing (22) which contains a cylindrical working chamber at different radial positions. Three or more passages extend through the housing and communicate with the working chamber. A piston (80) is positioned within the working chamber. The piston includes a duct (86) defined by its outer surface which communicates with one of the passages, depending upon its rotational position. The piston is rotated as it is driven back and forth within the cylinder, thereby causing the duct to sequentially communicate with the passages and the piston to sequentially close the passages. Depending upon the axial direction of movement of the piston, fluid is either pumped into or out of the working chamber as the duct rotates into communication with one of the passages. <IMAGE>

Abstract: The present invention concerns a catalyst for polymerization of olefins, said catalyst comprising an inorganic support material with catalytically active chromium and titanium compounds bound on its surface. The catalyst is prepared according to the invention by bringing the catalytically active metal compounds sequentially in vapour phase onto the support material surface in excess amounts in relation to the binding sites available on the support material surface. The support material temperature is maintained above the condensation temperature of the vapour, preferably above 160 DEG C, and simultaneously sufficiently high so as to achieve the thermal activation energy necessary for the generation of bonds between the support material and the catalytically active material or its compound. To avoid desorption of the chemisorbed compounds, the temperature is kept below approx. 500 DEG C. The activity of a catalyst in accordance with the invention even with very low contents of the catalytic metals is as high as the activity of a catalyst of multiply higher metal contents that has been prepared by the methods of the conventional technology.

Abstract: The invention comprises an improved method for installing a cable (4) in a tubular cable conduit (6) with the aid of the drag forces of a flowing medium and a pulling plug which can be used in this method. Coupled to the foremost end (8) of the cable in the conduit is a partially leaky pulling plug (10) which is provided with a flow opening (12) for the flowing medium. Said flow opening (12) is so dimensioned that, on the one hand, no harm is done to the drag forces of the flowing medium along the cable (4) but, on the other hand, a small pressure difference is maintained across the pulling plug, with the result that the pulling plug (10) energised in this way exerts additional tensile forces on the foremost end (8) of the cable (4) which compensate at least at that point for compressive forces arising as a consequence of intrinsic curvatures. Said flow opening is preferably such that during the installation of a cable the flow velocity in the flow opening (12) is essentially equal to that of sound in the flowing medium (shock wave condition). The flow opening (12) can be chosen as constant, but may also be regulated in a pressure-dependent manner to maintain the said shock wave condition better. Three embodiments of such a partially leaky pulling plug (10) are described, namely one having a constant flow opening, one in which the size of the flow opening varies with an essentially constant pressure difference across the pulling plug and one in which the size of the flow opening varies with the pressure at the position of the pulling plug. The pulling plug preferably has a circumferential suction seal with the inside wall (11) of the conduit (6). Advantages are reduction of the risk of upsetting and buckling, generally greater installation lengths in one stroke, and a lower compressor power. <IMAGE>

Abstract: The proposal is for a process for the high-frequency data transmission of driving information from fixed beacon transmitters (2, 4) to vehicles (7, 8) in which there are at least two fixed beacons. To prevent the extinction of the wave field of the at least two beacons (2, 4) by standing waves it is proposed to modulate the high-frequency signal of the beacon transmitters with a spectrum similar in noise so that standing waves cannot form. In this way all vehicles passing the beacons can receive the information transmitted by them without the occurrence of interference by the extinction of wave fields.

Abstract: Viterbi detector for a channel having a memory length 1, where no more than two survivors with an associated difference metric are updated. In the prior-art Viterbi detector of this type the new difference metric is derived by means of a saturation function from the previous difference metric. If the amplitude of the received signal differs from the values assumed for the calculation of the difference metric, the performance of the prior-art detector will rapidly degrade. In the detector according to the invention the new difference metric is derived from a saturation function of the previous difference metric, with the size of the linear region being dependent on the magnitude of the amplitude of the received signal. <IMAGE>   <IMAGE>
