Abstract: Products rich in plant cell wall, originating, for example, from higher plants which are naturally rich in pectins, from algae or from by-products, such as wheat bran, potato pulp, oil mill shells or residues, and the like, are modified so as to contain a fraction of water-soluble polysaccharides which is higher than, in particular which is equal to at least twice, that existing naturally, without modification of their overall chemical composition. To obtain them, water is added if need be to the natural product in the divided state, to form a mixture suitable for being subjected to a shearing treatment, and the resulting product is subjected to a shearing force before extrusion, resulting in modified products as aggregates which can be converted into powder. After aqueous extraction, conducted directly on the extruded product, a water-soluble fraction is obtained, from which, for example, pectins are isolated, with a degree of methylation >75%, and the extraction residue which, after drying and grinding, can be employed as alimentary fibres, like the extruded product which, having a low water content, can be employed directly.

Abstract: Novel siloxane-polyether polymers are provided containing cyclic siloxanes which are useful in silicone surfactants for foam polyurethane foam applications. The novel polymers are prepared by reacting a polyhydridosiloxane polymer with a cyclic polysiloxane containing a vinyl group and with an allyl started polyoxyalkylene polymer in the presence of a platinum catalyst. The resulting polymeric products are highly potent and impart flat breathability profiles to foams when used as surfactants in their preparation.

Abstract: The optoelectric transmitting and receiving device for an optical waveguide connecting section (2) has a mode-selective tapping element for splitting the light bundles transmitted bidirectionally on the common optical waveguide connecting section (2). A tapping element having a very high return attenuation is thereby produced with simple technical means. The mode-selective tapping for the light bundles to be transmitted and received is preferably achieved by means of optical components (7, 8, 11 to 15) such as prisms, stops and/or lenses. Embodiments are specified for the mode-selective tapping element.

Abstract: This invention provides an improved circuit for dynamically controlling a predetermined characteristic of each input channel of a system having a plurality of input channels to achieve a desired characteristic profile with predetermined time variances in channel aperture size and/or focal point depth. More particularly, the invention dynamically controls the gain of each input channel to maintain a desired apodization profile. A plurality of basic time varying functions are generated, such functions being, for example, a constant, a ramp, a parabola, an exponential or the like, and at least selected ones of the basic functions are combined by appropritely weighting the functions and adding the weighted functions to obtain a desired control signal. The control signal which has the desired dynamic gain characteristic for the given channel is then applied to control a gain-controllable amplifier for such channel. The number of combining elements may be reduced by providing such combining elements for only a selected number of spaced channels and by linearly interpolating the signals obtained from such combining elements for each pair of spaced channels to obtain control signals to control gain for channels between each pair of spaced channels. System gain may also be controlled by a signal generated by combining at least selected ones of the basic functions through weighting and adding.

Abstract: A light source 1 comprises a first layer 2 of plastics material, such as polycarbonate, incorporating two organic fluorescent dyes for emitting respectively, red and green light when excited by radiation of a shorter wavelength. A second layer comprising a phosphor material 3a is provided for emitting blue light when excited by an ultra violet radiating discharge caused by energisation of an electrode source electrode 6, the blue light serving to excite the organic fluorescent dyes of the layer 2. A barrier layer 3, such as phosphate glass, is provided between the first and second layers 2, 3a which serves to absorb ultra violet radiation and therefore prevents degradation of the first layer 2 of plastics material. The barrier layer 3 may also serve as a gas-impermeable layer to overcome the porosity of the plastics material of the layer 1. The red, green and blue light emissions from the device provide a white light source, although light of other colours may also be obtained.

Abstract: A strain gauge load cell is adjusted to zero output signal at no load or a fixed load on the load cell independent of the load cell temperature by shunting a pair of opposing arms of the strain gauge bridge by equal resistors (66′,66˝) between opposite terminals of the power supply (50) for the strain gauge bridge and opposite corners of the output terminals of the strain gauge bridge. The zero adjustment according to the invention is especially useful with load cell arrangements where individual strain gauge elements must have equalized sensitivities.

Abstract: A programmable logic device is constructed having a novel architecture. A plurality of control input signals are applied to a programmable mapping array in order to generate control functions for data path gating, latching, or modification. The programmable control functions provide flexibility to the designer, while the fixed data path logic is independent of the programmable array. The logic array and data path logic are fabricated on the same integrated circuit, therefore obviating the need for input/output buffers which would be necessary if the device were constructed utilizing discrete components. This enhances the performance of the device. Since the data path does not travel through the array, its performance is not affected by the programmability. If desired, the programmable array can be formed of mask programmable devices, fused programmable devices, or register based circuitry, for example, using RAM cells.

Abstract: The invention described herein suggests methods of cryptographic key management based on control vectors in which the control vectors are generated or derived internal to a cryptographic facility implementing a set of cryptographic operations. The methods of alternate control vector enforcement described in the present application provide a high-integrity facility to ensure that cryptographic keys are used in a manner consistent with the type and usage attributes assigned to the keys by the originator of those keys. Since the control vectors are generated or derived internal to the cryptographic facility on the basis of data contained in each cryptographic service request to the cryptographic facility, control vectors need not be stored or managed outside the cryptographic facility.

Abstract: An optical head device having an optical system provided with at least a light source (10), a shaping prism, an diffracting element (20) and a photodetector (60). The light source emits light whose intensity distribution has an elliptic shape in its cross section orthogonal to the optical axis. The shaping prism directs the light to a recording medium (70) after shaping the intensity distribution thereof into a circular shape. The diffracting element has diffracting regions formed by at least one division line substantially parallel to a reference direction. The light reflected from the recording medium forms an elliptic bright portion on the diffracting element. The photodetector is divided by a plurality of division lines (64, 65), at least one of which is parallel to the reference direction. When there is no focus error, the diffracting element diffracts the reflected light so as to converge it on the division line substantially parallel to the reference direction in the photodetector. For example, when the shaping prism is adapted to shape the elliptic intensity distribution with respect to its minor axis direction, the optical system is arranged so that the major axis of the bright portion is parallel to the division line of the diffracting element. Thus, it is possible to suppress offsets in focusing control due to wave-length variations of light.
