Patent CA-2149163-A1 (CA)
Inventor: DAUGHERTY JEFFREY WAYNE
IPC: H04Q1/457
Filed: 1995-05-11
Abstract: A first validation circuit utilizes residual energy unaccounted for by a linear predictive coding model for a specified order of model as a criteria on which to make a validity determination of whether a valid tone or digit has been received.  A second validation circuit operating in conjunction with the first validation circuit utilizes discrete Fourier transforms at the center and adjacent frequencies to energy peaks associated with tones.  A ratio of the peak energy to the adjacent energies is utilized in combination with  corresponding thresholds to make a validity determination.  The combination of the first and second validation circuit provides a high level of confidence that a particular tone or digit has been detected.
Patent CA-2152221-A1 (CA)
Title: Tire tread pitch bands
Inventor: HOFFMEISTER KURT M
IPC: B29C33/42
Filed: 1995-06-20
Abstract: The tread of the tire of this invention is made using tread bands that have a variable pitch length.  That is, the variable pitch length tread bands have a first pitch length of one axial side of the tread band and a second pitch length on the other axial  side of the tread band.   The transition between the first and second pitch lengths can be a gradual change across the tread band widthwise or a relatively abrupt change.  The preferred tire has a tread band where the change in pitch length is widthwise within a groove of the tread. Tread bands of this invention have circumferential edges that mesh with each other such that one variable length tread band can be used with its smaller pitch length on one lateral side of the tread or rotated end to end and used with the smallest pitch length on the other lateral side of the tread of the tire.  A method for producing a tread band having a change in the pitch length is also given in this invention.  The result is a tire that effectively has twice the number of pitch lengths sequenced around the tire as there are separate tread bands.  Reduced tread noise is achieved with a greater number of pitch lengths.  Alternately stated, the tread of the tire of this invention has a reduced tread noise when using the same number of different tread bands.   A single mold for providing a plurality of variable pitch length tread bands on the molded tire is also within the scope of this invention.

Inventor: KISS GUENTER H
IPC: C10J3/66
Filed: 1996-02-12
Abstract: A process for eliminating organic pollutant residues in the synthe- sis gas occurring during refuse gasification by the addition of oxygen is described, in which at least prepyrolyzed, carbon-cont- aining refuse in compressed form is fed into a high temperature reactor, where a loosely heaped up gasification bed is formed and is burnt below the same by O2 addition. The resulting synthe- sis gas is drawn off from the top area of the high temperature reactor after an adequate residence time and into the residence zone additional oxygen is jetted in temperature-regulated, partial quantities in such a way that the resulting possible partial combu- stion of the synthesis gas maintains its temperature above the gasification bed constant at approximately 1000°C. Oxygen jetting takes place in such a way that a completely homogeneous gas mixing is ensured in the top area. For this purpose several oxygen jets are arranged in the top area of the high temperature reactor and are axially and/or radially inclined thereto.

Title: Excreta deodorization method and apparatus
Inventor: FUSAO YAMADA
IPC: C02F3/12
Filed: 1994-10-11
Abstract: To provide excreta deodorization method and apparatus which prevent malodor emission from the treatment tanks, do not generate slurry, can dispense with the dipping-up of excreta, and therefore can dispense with the discharge of the treated excreta as sewage. Excreta deodorization method and apparatus whereby excreta flowing from a toilet are completely decomposed by aerobic bacteria in a pretreatment tank and a main treatment tank and discharged in the form of carbon dioxide and water vapor. Excreta (3) flowing into a pretreatment tank (1) from a toilet (A) are preliminarily decomposed by aerobic bacteria by blowing air into the tank (1) and the decomposed excreta overflow into a main treatment tank (12), where the excreta (14) are completely decomposed into carbon dioxide while keeping the bacteria at the optimum working temperature by using a heater (22) and blowing air into the tank (12) from a blower (15) through a tubular foot (18). The generated carbon dioxide is thus deodorized and discharged through a ventilator (27). Also malodorous ammonia is deodorized, because it is decomposed into hydrogen and nitrogen gases by the action of the aerobic bacteria.
