Abstract: A gas-flow type chipping machine with a rotating beater-wheel system. In order to chip the feed material, this material is delivered axially into the central area of the beater wheel, where it is deflected and moved in a radial direction to the chipper tools that are arranged in a circle around the beater wheel. In order to ensure that the wear is even along the length of the chipper tools, at least two impact surfaces are arranged so as to be axially staggered to the depth of the chipping space, the impact surface that follows in the axial direction of delivery projecting beyond the axial projection of the preceding impact surface. In addition to the foregoing, the present invention discloses a method for optimizing the size and position of the impact surfaces of a chipping machine according to the present invention.

Title: Method for preparing an emulsified fuel and implementing device
Inventor: SCHULZ PHILIPPE
IPC: B01F25/60
Filed: 1999-12-08
Granted: 2009-02-03
Abstract: The invention concerns a method for preparing an emulsified fuel, such as for example a water-in-diesel oil or a water-in-gasoline emulsion, to be used for powering spark ignition engines or in energy-producing appliances. The invention aims at enabling the production on an industrial scale of emulsions stable for at least four months, wherein the external phase is organic and the internal phase aqueous. Said aim is achieved by the inventive method which consists in mixing the organic phase, the aqueous phase and additives to homogenise into a volume V of liquid comprising the organic phase and the additives by circulating the latter at a homogenising capacity at a flow rate Qc such that the ratio Qc/V >/= 100<h-1>, in circulating the homogenised liquid in an external branch loop comprising an emulsifier system with a flow rate Qcirc such that the ratio V/Qcirc ranges between 0 and 2 h, and in supplying the branch loop with water upstream of the emulsifier system, until the desired characteristics of storage stability for the emulsion are obtained. The invention also concerns the device for implementing said method.

Abstract: A broadband communication network uses a point and shoot approach for data transmission. A transmitted broadband information signal is divided into a series of data packets, each including addressing information for a particular receiver. The information signal is parsed to extract addressing information, which is parsed to construct a narrow band index signal. This index signal is transmitted to a plurality of receiving stations. Each receiving station demodulates and decodes the narrow band index signal. The address information contained in the index field includes pointers to data packets in the information signal. Using the addressing information and pointers, each receiving station can locate and extract data packets from the broadband information signal which are intended for that particular receiver. The data packets from the information signal are buffer to permit demodulation and decoding the particular packet(s) belonging to that particular receiver at the same rate of the information signals.

Abstract: The invention relates to a composition for use in a dishwasher which is provided in the form of a tablet. The inventive composition is characterized by a base composition which essentially carries out its function during the main cleaning cycle of the dishwasher, and is also characterized by at least one particle. Said particle has at least one core that comprises at least one substance which essentially carries out its function during the rinse cycle of the dishwasher. The particle also has a coating which, for the most part, completely surrounds the core(s). Said coating comprises at least one compound whose solubility increases with a declining concentration of a specific ion in the surrounding medium. The at least one particle is arranged in or on the tablet in such a way that the surface of the particle(s) is, at most, partially in direct contact with the surface of the base composition surrounding this/the se particles. In order to prevent the coating from substantially dissolving or to prevent the coating from substantially detaching from the core(s), the concentration of the specific ion in the local surrounding of the particle(s) is sufficiently high until the tablet has, for the most part, completely dissolved. The invention also relates to a method for conducting a dishwashing cycle in a dishwasher while using the inventive composition.

Abstract: A method and associated apparatus are disclosed for measuring volatile content of samples that are particularly suitable for samples that tend to burn when heated. The method includes the steps of applying microwave radiation at a predetermined power level to a moisture-containing sample to drive volatiles from the sample, monitoring the weight of the sample during the application of microwave power, monitoring the temperature of the sample during the application of microwave power without contacting either the sample or anything in contact with the sample, and moderating the microwave power being applied to the sample based upon the monitored temperature to maintain the temperature of the sample at or below a pre-determined set point temperature below which the sample will not burn. In its apparatus aspects, the invention includes a cavity for holding a sample for which the volatile content is to be determined; an infrared photosensor positioned to measure the temperature of a sample placed within the cavity, an analytical balance for measuring the weight of the sample while the sample is in the cavity, a power source for introducing microwaves into the cavity, and a processing unit in communication with the infrared photosensor and the power source for controlling the introduction of microwave energy to the cavity in response to the infrared photosensor to prevent the sample from reaching temperatures at which the sample would burn.

Title: Process for the manufacture of liquid filled capsules
Inventor: ALEX RAINER
IPC: A61K9/48
Filed: 1999-11-11
Granted: 2006-06-20
Abstract: The present invention relates to a process for encapsulating a shear sensitive fill mass into a capsule, characterised in that said fill mass is heated and subsequently cooled, immediately prior to the encapsulation. The invention relates also to the capsules obtainable by the said process. The process according to the present invention enables to obtain capsules showing high and constant dissolution rates. The amount of active agent intake can be therefore reduced since the active agent itself is rapidly dissolved. The overall costs of the medicament are thereby also reduced. The high homogeneity (and therefore the high and constant dissolution rate) of the capsules produced with the process according to the present invention guarantees a reproducible bioavailability and therapeutic effect of the active agent which is contained in it.

Granted: 2004-11-23
Abstract: This invention relates to communications (radio) receiver circuitry and, in particular, to circuitry for eliminating a varying DC distortion component of a demodulated received information signal such as comprising data packets. This invention uses an adaptive filter, and a corresponding adaptive (equalization) feedback signal, to remove a slow varying (exponential) DC component of the signal. In the decoding circuitry of a receiver the adaptive filter (e.g. an LMS filter) compares the outputs of an integrate and dump component to adapted outputs of a decision component in order to produce an error signal which inherently corresponds to the varying DC component of the symbol stream. This equalizing adaptive error signal is fed back and subtracted from the symbol integral stream to remove the varying DC component therefrom and thereby restore the information packet to a level DC bias condition.

Granted: 2007-07-10
Abstract: A drilling method in which a rotary drill bit is mounted on a tubular drillstring (32) extending through a bore comprises:  drilling through a formation (33) containing fluid at a predetermined pressure; circulating drilling fluid down through the drill string (32) to exit the string at or adjacent the bit, and then upwards through an annulus (50) between the string and bore wall; and adding energy to the drilling fluid in the annulus at a location above the formation (33). The addition of energy to the fluid in the annulus (50) has the effect that the pressure of the drilling fluid above the formation (33) may be higher than the pressure of the drilling fluid in communication with the formation and that predetermined differential may be created between the pressure of the formation fluid and the pressure of the drilling fluid in communication with the formation.
