Title: Machine for automatically positioning and feeding containers
Inventor: SALA JAIME MARTI
IPC: B65G47/57
Filed: 1990-12-07
Granted: 1994-04-19
Abstract: ABSTRACT OF THE DISCLOSURE           A machine for automatically positioning and feeding containers  includes  a  main  hopper  for  receiving  randomly containers, and a bottom with a peripheral edge portion at a distance from the side wall of the hopper to provide a space through which the containers can drop by gravity towards a lower section.  A lateral aperture in the side wall of the hopper in a curved lateral area precedes the container unloading station, the aperture being adapted to remove, mainly by centrifugal force, malpositioned containers housed only partially in and protruding from holding and transporting units,  or located external to them and conveyed by other containers.  The aperture communicates with a recovering auxiliary hopper, external to the main hopper and a coupled belt type conveyor associated with the external hopper for recycling containers into the loading area preceding the lateral aperture.  An air jet, or at least one rotating brush, impinging on containers not correctly positioned may be incorporated as a supplement to the action of centrifugal force.

Title: Treatment of gases
Inventor: WATSON RICHARD WILLIAM
IPC: B01D53/52
Filed: 1992-02-13
Granted: 2003-04-15
Abstract: A gas stream comprising hydrogen sulphide is preheated in a heat exchanger 2. Part of its hydrogen sulphide content is burnt in a furnace 6 to form sulphur dioxide and Water vapor. Pure oxygen or oxygen-enriched air is used to support combustion. The sulphur dioxide reacts with residual hydrogen sulphide to form sulphur vapor and further water vapor. The sulphur vapor is removed from the gas stream in a condenser 14. The gas stream is then divided into first and second subsidiary streams. The hydrogen sulphide content of the first subsidiary stream is totally converted to sulphur dioxide in an incinerator 16 using pure oxygen or oxygen-enriched air to support its combustion. Water vapor is then removed from the first subsidiary stream in a condenser 20, and the resulting gas stream now relatively rich in sulphur dioxide, is recycled to the furnace 6. The second subsidiary stream is subjected to a plurality of stages 26 of catalytic reaction between hydrogen sulphide and sulphur dioxide to form further sulphur vapor which is removed therefrom.

Title: Process for finding the overall monitoring threshold during a bit-rate-reducing source coding
Inventor: ROSINSKI KLAUS
IPC: H03H17/02
Filed: 1992-07-21
Granted: 1998-09-22
Abstract: In order to find the overall monitoring threshold during a bit-rate-reducing source coding of digitized audio signals, a requantization and coding regulation for the time or spectral scanning values of the audio signal is found from the masking effect of all relevant maskers and noise maskers and from the steady audio threshold.  To this end the masking sides of the selected maskers are segmented and approximated in the individual segments by low-order polynomials, whereby the coefficients of the low-order polynomials are found.  The intensities of the maskers converted into a logarithmic level are used to find the coefficients of the low-order polynomials. The overall monitoring threshold is found at individual or eventually selected support points in steps, masker by masker, from the polynomials describing the masking sides of the eventually selected maskers.
Patent CA-2108536-C (CA)
Inventor: AGAZZI OSCAR ERNESTO
IPC: G06K9/70
Filed: 1993-10-15
Granted: 2000-04-04
Abstract: Pseudo two-dimensional hidden Markov models (HMMs) are used to represent text elements, such as characters or words. Observation vectors for each text element are based on pixel maps obtained by optical scanning. A character is represented by a pseudo two-dimensional HMM having a number of superstates, with each superstate having at least one state. Text elements are compared with such models by using the Viterbi algorithm, first in connection with the states in each superstate, then the superstates themselves, to calculate the probability that a particular model represents the text element. Parameters for the models are generated by training routines. Probabilities can be adjusted to compensate for changes in scale, translations, slant, and rotation.      An embodiment is also disclosed for identifying keywords in a body of text. A first pseudo two-dimensional HMM is created for the words that may appear in the text. Each word in the text is compared with both models, again using the Viterbi algorithm, to calculate probabilities that the model represents the subject word. If the probability for the keyword is greater than that for the extraneous words, the subject word is identified as being the keyword. Preprocessing steps for reducing the number of words to be compared can be added.

Granted: 1998-09-15
Abstract: A door closer (20) is attachable to a door (24) and includes a cylinder (36) which forms a chamber (44) in which a piston element (50) is movable to move fluid from the chamber to a reservoir (82) upon opening of the door.  After the door (24) has been opened to a position, for example, of ninety-five to one hundred degrees, continued opening of the door causes the fluid to be compressed within the chamber (44) and to be directed only through a back check valve (95) to the reservoir (82).  This results in the development of an adjustable "back check" condition to provide a counterforce to the continued opening of the door.  A passageway (150) is formed in cylinder (36) to allow fluid to flow relatively freely from chamber (44) to reservoir (82) until an inward end (56) of piston element (50) has travelled a prescribed distance "x." This prescribed distance of travel represents the opening of door (24) to ninety-five to one hundred degrees from the door's normally closed position.
