Title: Node for a fast packet-switching network in optical-electrical technology
Inventor: DE BOSIO ALFREDO
IPC: H04B10/27
Filed: 1989-02-28
Granted: 1994-07-26
Abstract: ABSTRACT       A node for a fast packet-switching network in hybrid optical-electrical technology has an optical switching matrix and an electrical control portion which processes signal packets and the headers of information packets. The control portion updates the label of information packets held in an optical buffer and, depending on such a label, searches for a routing through the node.  A centralized node controller processes the signal packets,  while a distributed input processing system processes the information packet headers and  routes  the  packets  through  the  network.  For  all communications in progress, the distributed input processing system periodically forwards routing requests towards an electrical self-routing switching matrix associated with the optical matrix; when a connection path has been found between an input and an output of the electrical matrix, the same path is reproduced in the optical matrix and the packets are transferred from the optical buffer to the node output through the optical matrix.

Abstract: A convenient method is provided for preparing a stabilized aqueous enzyme dispersion. The method comprises precipitating a water-soluble polymer from aqueous solution to form an aqueous dispersion, and before, during or after the precipitation step, contacting the dissolved or dispersed polymer with an aqueous solution or fine aqueous dispersion of enzyme.      Using this method, substantial improvement of the enzyme stability during storage can be obtained with surprisingly little polymer (relative to enzyme) and enzyme stabilization can, surprisingly, even be obtained by contacting precipitated polymer with dissolved enzyme. The stabilizing effect therefore appears not to be due (or at least not primarily due) to encapsulation.

Abstract: SNOW PLOW ARRANGEMENT FOR MOISTURE RETENTION IN A FIELD ABSTRACT OF THE DISCLOSURE A snow plow member is attached to selected ones of the shanks of a cultivator frame by inserting the leading edges of the sweep at the lower end of the shank into slots formed on the rear surface of the snow plow member. A leading edge of the snow plow member follows the C-shaped curvature of the shank. The shank is clamped to the underside of the snow plow member. With such snow plow members attached to selected ones of the cultivator shanks, the snow flow members can be used to form furrows in the snow which acts to trap additional snow and to prevent the snow from being stripped from the field. The resultant increased accumulations of snow provide additional moisture retention for the field.

Abstract: ABSTRACT            Apparatus and method for distributing data from a central digital data processing system to remote digital data processing systems and apparatus for storing data in digital data processing systems.  The central digital data system creates a data descriptor which describes the data and its source location.  The central system provides the data descriptor to the remote systems.  The remote systems employ the data descriptor to retrieve the data to be distributed and place it in a destination.  A given digital data processing system may function as both a central system and a remote system.  The data descriptor may be provided to the remote systems by means of magnetic media or a network and the data may be retrieved from magnetic media or via a network.  When retrieval is via a network, the source of the data is an inventory library.  The inventory library may be part of the central system or may be part of a different host system. The destination includes a live library and a run library.  The data is retrieved to the live library, and when it is to be used, the remote system installs the data by placing it in the run library.  Both test and production versions of data may be present in the destination and a test version may be converted to a production version.  If both test and production versions are simultaneously present, one is always in the live library and the other always in the run library.

Abstract: A vehicle transmission, particularly for industrial and agricultural vehicles, includes a speed change gearset (gear and range) and a central differential for distributing the gearset output to the front and rear axles of the vehicle. The central differential is formed of a Ravigneaux gearset to reduce the dimensions of the transmission and to minimize the costs and technical resources required to produce it. The Ravigneaux gearset distributes the torque of a gear output shaft to the front and rear axles according to the ratio of the two planetary sun gear diameters. Preferably, the end stage of the speed change gearset is formed by a further gearset, and the planet carriers of both Ravigneaux gearsets are formed as a common structural member carrying the planets of both Ravigneaux gearsets.

Abstract: A catalytically active powder, its preparation, and its use for activating insulating substrates to receive electrolessly deposited metal in a coherent metal layer are described. The powder of the invention comprises a plastic powder containing catalyzing/activating chemical compounds allowing that the acceleration of the catalyst is not carried out until the powder is melted down onto the substrate. The substrate need not be etched prior to the metallization since the plastic melted down ensures a good adhesion between metal and plastics and between plastics and substrate. Furthermore, the colloidal nature of the catalyzing compounds is stabilized in a particular and especially durable manner by the plastic powder. The use of the powder causes less risk to the environment since the catalyst may be applied as a dry powder, and since the etching of the substrate is avoided.

Abstract: In a cognition device for battery residual capacity, battery voltage information and battery ambient temperature information are input to a microprocessor through an A/D converter.  In the microprocessor, the voltage information is corrected with load information; the data conforming to the ambient temperature information are read out of the battery discharge characteristic data which are previously stored in memory, and the readout data are compared with the corrected voltage information so that the battery residual capacity can be computed from the result of the above comparison data.  In this arrangement, it is therefore possible to accurately recognize battery residual capacity at an arbitrary point in time.
