Abstract: PCT No. PCT/EP95/00855 Sec. 371 Date Sep. 25, 1996 Sec. 102(e) Date Sep. 25, 1996 PCT Filed Mar. 8, 1995 PCT Pub. No. WO95/24724 PCT Pub. Date Sep. 14, 1995The invention concerns a switching arrangement for load change-over switches of step switches and for selector switches, wherein two switching contacts movable in two directions are present. The first switching contact is in the form of a main switching contact and is connected to the load derivation by means of a first vacuum switchgear cell. The second switching contact is in the form of a resistance switching contact which is likewise connected to the load derivation by means of a series connection comprising a second vacuum switchgear cell and a transition resistor.

Title: Non-woven fiber mat and method for forming same
Inventor: HELWIG GREGORY S
IPC: D04H1/70
Filed: 1997-03-19
Abstract: The present invention is a non-woven fiber mat suitable for reinforcing resilient sheet floor coverings, such as vinyl floor coverings. The non-woven fiber mat is in the form of a sheet of reinforcement fibers which at least includes semi-coiled fibers and can also include coiled fiber, with one or more turns, and even some relatively straight or slightly curved fibers. It is desirable for most, if not all, of the reinforcement fibers to be made from glass. However, it may also be desirable for the reinforcement fibers to include glass fibers and synthetic fibers. It may even be possible for the reinforcement fibers to include only non-glass fibers. At least one polymeric binder is used for bonding together the reinforcement fibers so as to make the fiber mat a suitable substrate for reinforcing resilient sheet floor coverings, such as an interlayer for vinyl floor coverings. By using a non-woven fiber mat containing reinforcement fibers that are not completely straight and capable of interlocking with one another, a resilient sheet floor covering made with such a mat can exhibit improved planar compressibility.

Title: Process and device for purifying water, in particular from a composting process
Inventor: SCHNORR KARL-ERNST
IPC: C02F1/44
Filed: 1995-04-13
Abstract: Water, esp. condensate, from a compost plant, is oxygenated, especially by aeration. It is then filtered by reverse osmosis. The raw condensate is first modified, to facilitate biological clarification. The content of the water, determining oxygen demand, is measured; the quantity of material to be separated out is determined. Raw condensate is inoculated, to set the metabolic functions of the micro-organisms. The predetermined material to be separated, is filtered out. Metabolism in the bio-reactor is oxygen-controlled, esp. by air input, and/or the nutrient input, and/or pH control, and/or temperature control. Filter performance, esp. membrane filter performance, is controlled by pressure and/or throughput. Also claimed are: The use of a bio-reactor, a composting process, and composting equipment. <IMAGE>

Title: Non-separable starch-oil compositions
Inventor: ESKINS KENNETH
IPC: A23L27/00
Filed: 1995-04-21
Abstract: A stable and non-separable composition comprised of starch and oil can be prepared in the absence of external emulsifying or dispersing agents by thoroughly solubilizing an aqueous dispersion of the starch at elevated temperatures and incorporating the oil into the non-retrograded starch under conditions of high turbulence. The resulting dispersions form soft gels that can be easily converted to pourable fluids by the application of heat. Upon drying, these dispersions yield solid compositions that are easily redispersed in water to form smooth, stable dispersions that are nongreasy, yet slippery to the touch. These compositions are useful as thickening agents, suspending agents, fat substitutes, and seed coatings. They are receptive to the addition of a variety of water-immiscible materials, such as volatile and essential oils, food flavorants, medicinals, agricultural chemicals, and the like.

Patent AU-2668199-A (AU)
Title: Multiple access method and system
Inventor: SHATTIL STEVEN J
IPC: H04B1/7115
Filed: 1999-02-10
Abstract: Carrier Interferometry (CI) provides wideband transmission protocols with frequency-band selectivity to improve interference rejection, reduce multipath fading, and enable operation across non-continuous frequency bands. Direct-sequence protocols, such as DS-CDMA, are provided with CI to greatly improve performance and reduce transceiver complexity. CI introduces families of orthogonal polyphase codes that can be used for channel coding, spreading, and/or multiple access. Unlike conventional DS-CDMA, CI coding is not necessary for energy spreading because a set of CI carriers has an inherently wide aggregate bandwidth. Instead, CI codes are used for channelization, energy smoothing in the frequency domain, and interference suppression. CI-based ultra-wideband protocols are implemented via frequency-domain processing to reduce synchronization problems, transceiver complexity, and poor multipath performance of conventional ultra-wideband systems. CI allows wideband protocols to be implemented with space-frequency processing and other array-processing techniques to provide either or both diversity combining and sub-space processing. CI also enables spatial processing without antenna arrays. Even the bandwidth efficiency of multicarrier protocols is greatly enhanced with CI. CI-based wavelets avoid time and frequency resolution trade-offs associated with conventional wavelet processing. CI-based Fourier transforms eliminate all multiplications, which greatly simplifies multi-frequency processing. The quantum-wave principles of CI improve all types of baseband and radio processing.
