Title: Cleaning exhaust gases from combustion installations
Inventor: HUG HANS THOMAS
IPC: F01N13/02
Filed: 1993-02-03
Granted: 1999-11-16
Abstract: In a process for, cleaning the exhaust gases from combustion installations, a dilute urea solution prepared in a reagent tank (20) is introduced into the hot exhaust gas flow (30) of differing concentrations and is finely sprayed in the direction of the exhaust gas flow.      After decomposition of the urea in a pyrolysation channel (14), the exhaust gas flow (30) is homogeneously mixed in-line by a mixer located in a mixing channel (16). In a subsequent in-line reaction channel (18), the reducible exhaust gas constituents are converted into non-toxic gases in at least one selective reduction catalyst which does not contain zeolite (36), then, dependent on the installation, the oxidisable exhaust gas components are converted into non-toxic gases without reagent in at least one oxidation catalyst (38) to produce a virtually complete reaction.      A dual substance nozzle appliance (26) opening into the pyrolysation channel (14) comprises a reversing valve (88) for the working and blowing out position, a casing tube (24) for the compressed air, located in the area of the exhaust gas flow (30), a urea conductor carried at a distance in the casing tube (24) and a nozzle for fine spraying of the dilute urea solution.

Abstract: A method of enforcing a regular manganese dioxide cathode to become gradually and substantially rechargeable is described, where the cathode capacity is increased towards the theoretical capacity of the cathode. The method involves mixing 20-51 wt% MnO2, 5-25 wt% metallic bismuth and 30-70 wt% graphite powder to form a homogenous mixture, subjecting the mixture to a pressing force to form an electrode and subjecting the electrode to successive discharge/charge cycles at a rate where the cathode capacity becomes greater than 75 % of the theoretical capacity after 4-11 cycles. The method provides for a simple and inexpensive way of forming a rechargeable manganese dioxide cathode without complex chemical synthesis.

Abstract: An apparatus and method. for continuously loading containers into cartons in oriented two row arrays is provided. A supply delivers the containers individually to a depositing device for individually receiving respective containers. The depositing device is then moved to individually deposit the containers delivered thereto in a first collection device for collecting the containers in rows and columns corresponding to the array. The first collection device includes a matrix of dedicated channels similar to the array into which channels the depositing device deposits the containers in a sequential manner whereby the matrix is repeatedly filled with the containers row by row. Individually and alternately after each associated row of the matrix is filled, each row of containers in the first collection device is next delivered to a second collection device for collecting the containers in separated rows. The second collection device includes a respective bay for each respective row of the array of containers. After collecting the containers in two separated rows in the second collection device, and after presenting a carton adjacent the second collection device, the two separated rows of containers in the two bays of the second collection device are fed as the array into the presented carton.      All of the containers in the rows in the second collection means are positively fed into the adjacent carton with a positive feed device which also serves to eliminate partially or unfilled containers from the array.

Abstract: A framing and voice decoder part outputs an error information. An error ratio monitoring part monitors a bit error ratio based on the error information. A sampling rate changing part decides a sampling rate based on the bit error ratio and changes a number of bits of each shift register in the differential detector part to adapt the sampling rate. A sampling clock selector part selects one clock signal among four different frequency clock signals based on the decision of the sampling rate changing part and gives selected clock signal to the differential detector part as a sampling clock.      The differential detector part makes demodulation in DQPSK (Differential Quadrilateral Phase Shift Keying). Since the error ratio is always maintained within a predetermined extent, a good voice quality is obtained. Since the sampling rate will not increase to unnecessarily high levels, power saving can be achieved and a consumption of batteries is reduced.

Furthermore, compared with the prior art, a higher concentration and a lower viscosity, so that the resulting primer composition shows excellent penetration into the substrate at high concentration and provides for sufficient substrate-reinforcing and water-proofing effects.          Moreover, when forming a film thereby and forming a finish layer thereon, this composition shows a high affinity for the top coating or adhesive to insure a firm integration of the finish layer with the substrate surface.
