Title: Rheology modification and modifiers
Inventor: PALMER ANTHONY MARTIN
IPC: C06B47/14
Filed: 1998-05-15
Abstract: We have now found that associative thickeners may be used in emulsions for use in explosive compositions, which associative thickeners provide for rapid and reversible changes in emulsion viscosity. Associative thickeners provide explosives emulsions having the desirable characteristics of (1) significant reduction in viscosity during pumping and (2) reestablishment of relatively high viscosity when pumping is terminated without damage to the emulsion components. It is believed that the associative thickener provides a network of physical linkages throughout the emulsion which network can be reversibly broken down.

Patent CA-2297599-A1 (CA)
Inventor: OHLEMEYER HEINRICH
IPC: A01F29/10
Filed: 2000-01-28
Abstract: A self-propelled forage harvester is provided with a throughput measurement device comprising a computer which makes use of respective signals representative of the displacement of a movable upper pre-compression roll relative to a fixed lower pre-compression roll, of the speed of the lower roll, and of the force exerted by the mat of crop passing between the rolls on the upper roll once the upper roll reaches its upper limit position in the calculation of the crop throughput value. An additional input signal that may be used in the calculation of the crop throughput is generated by a light barrier which determines whether or not any crop is exiting the discharge chute of the forage harvester, this signal causing the throughput calculation to indicate zero throughput when no crop is exiting and causing the calculation to indicate a minimum amount when the upper pre-compression roll is in its lower limit position with crop being sensed exiting the discharge chute.

Title: Method for producing fatty acid methyl ester and equipment for realising the same
Inventor: PANNING PETER
IPC: C07C67/03
Filed: 1998-11-23
Abstract: The present invention relates to a method and an equipment for producing fatty acid methyl ester, more particularly diesel fuel for vehicles, wherein said method allows for a rational production in economical equipment, preferably in large-scale industrial equipment. A container (1) contains saturated and unsaturated higher fatty substances from vegetal and/or animal origin. A tank (2) is provided for a potent alkaline solution, particularly a potassium solution, while another tank (3) is provided for the alcohol, particularly for methanol. The alkaline solution is dissolved in the alcohol and this operation is carried out in a mixing vessel (4). The container (1) containing the fatty substances and the mixing vessel (4) are connected at the transesterification section (8). The reaction or transesterification section (8) comprises a static mixer (12) that creates a whirlpool in the liquid due to the action of high or powerful turbulence. The phase separation surfaces are thus substantially increased so that chemical balance can be achieved more rapidly. The liquid which is at the chemical balance state is then supplied to a distillation unit (15). The target substances, such as the fatty acid methyl ester, are correspondingly removed from the stages (18) of the distillation unit (15). This invention enables for the first time the production of diesel fuel such as eco-diesel or bio-diesel in ecologically optimal conditions of production while maintaining all the advantages thereof.

Abstract: Disclosed is an illumination system using optical feedback to maintain a predetermined illumination output. The illumination system employs an electrically controllable optical filter for filtering light incident thereon. The illumination system also includes a light detector for detecting at least a portion of the light filtered by the electrically controllable optical filter. The light detector is in data communication with the electrically controllable optical filter. Some or all light filtered by the electrically controllable optical filter is detected by the light detector, which, in turn generates a corresponding signal that is compared to at least one predetermined value. If the signal generated by the light detector differs when compared to the at least one predetermined value, one or more filtering characteristics of electrically controllable optical filter are varied which, in turn, varies the amount of light filtered by the electrically controllable optical filter. The filtering characteristics of the electrically controllable optical filter continue to be varied until the signal generated by the light detector substantially matches the at least one predetermined value.
