Abstract: A dough divider (120) is operable within a mixer bowl (110) to divide the dough (116) into preset weights (e.g., for bread, loaves, buns). A pendulum assembly (140) has a retractable knife sleeve (146) to cut a charge of dough, which is compressed by a piston (148). The charge of dough is expelled into a scaling die cylindr (129) and causes a scaling die piston (131) to be retracted until a preset weight of dough is in the scaling die cylinder (129). As the knife sleeve (146) moves out of alignment with the scaling die cylinder (129), any excess dough is cut off and the preset weight of dough is then expelled by the scaling die piston (131).

Title: Method for setting up a telephone connection and an exchange system
Inventor: JYVAELAE PETRI
IPC: H04Q3/64
Filed: 1996-05-23
Granted: 2004-07-20
Abstract: The invention relates to a method for setting up a telephone connection in a telephone system which system comprises several exchange systems (100 and 116). The invention also relates to an exchange system (100) operating in accordance with the method. A queuing list is used in the method, which list is maintained in such a manner that when no free connection is available, the operator (107) places information about the received call order in the queuing list to wait for a connection to become free. In the method, the loading of connections (108a to 108c, 114 and 115) is monitored and when the required connection (108a to 108c, 114 and 115) is detected to be free, the connection (108a to 108c 114 and 115) is reserved for the use of the operator (107) and the operator (107) is sent information about the call order on the queuing list. After this the operator (107) can put the call through. The method makes the search for free connection automatic in congested directions and therefore the work of operators (107) will be easier.

Abstract: White liquor produced from black liquor is partially or completed oxidized. The white liquor contains dregs that are utilized as a carbon based catalyst. Dregs are produced by separating the dregs from green liquor an intermediate product between the black liquor and the oxidized white liquor. After formation of the oxidized white liquor, the dregs are separated therefrom to form a waste dreg stream which can be recycled so that part of the dregs present within the dregs containing white liquor stream to be oxidized is contributed by the waste dreg stream.

Abstract: An exhaust manifold (7) of an en- gine (I) is connected to a three way (TW) catalyst (8a), and the TW cata- lyst (8a) is connected to an NHs ad- sorbing and oxidizing (NH3-AO) cata- lyst (10a). The engine (I) performs the lean and the rich engine operations al- ternately and repeatedly. When the en- gine (1) performs the rich operation and thereby the exhaust gas air-fuel ratio of the exhaust gas flowing into the TW catalyst (8a) is made rich, NO x  in the inflowing exhaust gas is converted to  NHs in the TW catalyst (8a). The NH3 is then adsorbed in the NH3-AO cata- lyst (10a). Next, when the engine (1) performs the lean operation and thereby the exhaust gas air-fuel ratio of the ex- haust gas flowing into the TW cata- lyst (8a) is made lean, NO x in the ex- hausted gas passes through the TW cat- alyst (8a), and flows into the NHs-AO catalyst (10a). At this time, NH3 ad- sorbed in the catalyst (10a) is desorbed therefrom, and reduces the inflowing  NO x.

Title: Gross pollution filter
Inventor: ROY SCOTT WADE
IPC: E03F5/14
Filed: 1997-10-23
Granted: 2006-07-11
Abstract: A water filter arrangement (10) for trapping gross pollutants flowing in a storm water system is provided in-line or at end-of-line of a storm water pipe. The arrangement comprises an inlet (14) and an inlet area (18) which directs incoming water (16) into a filter (20). The filter traps entrained gross pollutants and filtered water exits the filter via filter outlet (50). The outlet (50) and surrounding walls (58 and 57) are shaped to create a flow of filtered water which forms a water barrier which restrains the flow of water and gross pollutants from the inlet (14) to the outlet (52). The water barrier is located between the inlet (14) and the outlet (52) preferably closer to the outlet than the inlet. As the filter (20) becomes full and the flow of filtered water exiting the filter decreases the water barrier subsides. When the filter is completely blocked, the water banger completely subsides and the incoming water and gross pollutants by-pass the filter (20) and flow unrestrained without head loss from the inlet (14) to the outlet (52).

Title: Speech coding apparatus and speech decoding apparatus
Inventor: OZAWA KAZUNORI

Granted: 2004-11-02
Abstract: A speech coding apparatus includes a spectrum parameter calculation section, an adaptive codebook section, a sound source quantization section, a discrimination section, and a multiplexer section. The spectrum parameter calculation section receives a speech signal and quantizes a spectrum parameter. The adaptive codebook section obtains a delay and a gain from a past quantized sound source signal using an adaptive codebook, and obtains a residue by predicting a speech signal. The sound source quantization section quantizes a sound source signal using the spectrum parameter. The discrimination section discriminates the mode. The sound source quantization section has a codebook for representing a sound source signal by a combination of non-zero pulses and collectively quantizing amplitudes or polarities of the pulses in a predetermined mode, and searches combinations of code vectors and shift amounts used to shift the positions of the pulses to output a combination of a code vector and shift amount which minimizes distortion relative to input speech. The multiplexer section outputs a combination of outputs from the spectrum parameter calculation section, the adaptive codebook section, and the sound source quantization section.

Title: Demodulateur numerique pour transmission hierarchisee
Inventor: HASHIMOTO AKINORI
IPC: H03D3/00
Filed: 1998-11-30
Granted: 2008-04-08
Abstract: L'invention porte sur un démodulateur numérique pour transmission hiérarchisée capable de créer un synchronisme stable et de réaliser une démodulation stable en effectuant les opérations de démodulation à partir d'une valeur C/N en réception. La valeur C/N en réception est mesurée par un circuit de mesure CNR (10) lors de la réception de la sortie démodulée d'un circuit arithmétique (1). La reproduction de la porteuse s'effectue sur la base d'une sortie démodulée obtenue par démodulation de l'onde modulée dans une en-tête. L'onde modulée d'un signal de salves de symbole dans la période allant jusqu'à l'établissement du synchronisme, après acquisition synchrone, donne la sortie de démodulation dans l'en-tête à partir d'une sortie de porte logique (11). La reproduction de la porteuse intervient sur la base du signal de salves de symbole et d'un signal QPSK pour une valeur intermédiaire de C/N. Lorsque la valeur de C/N est élevée ou basse, le démodulateur commute une boucle de reproduction de porteuse sur un gain plus élevé. On utilise pour cela un circuit (8) de commande de porte déclencé par un signal fourni par la porte logique (11).
