Title: Modular emergency or weather alert interface system
Inventor: GROPPER DANIEL R
IPC: G08B21/10
Filed: 1995-03-06
Granted: 1999-05-04
Abstract: This invention relates to an automatic, emergency or weather alert interface system between a first communication system, on which an emergency alert signaling tone is transmitted to indicate the occurrence of an emergency condition, and a second communication system, different from the first communication system. In operation, an emergency alert signaling tone is received from the first communication system by the emergency alert interface system which causes a prerecorded alert message to automatically be transmitted on the second communication system for an adjustable number of cycles wherein the audio from the prerecorded alert message is mixed with the audio from the second communication system so as to permit both audio messages to simultaneously be transmitted on the second communication system.          Additional features taught herein include the transmission of a subaudible signaling tone on the second communication system to permit listeners on the second communication system to filter out all non emergency communication on that system until the subaudible signal is transmitted and the ability to permit a second communication system listener to access and link the first communication system to the second communication system to permit immediate access to the alert message on the first communication system through the second communication system.

Inventor: LIOU KANG-YIH
IPC: H01S5/026
Filed: 1995-05-11
Granted: 1999-11-02
Abstract: A semiconductor laser has been developed which is capable of efficiently transmitting a predetermined number of modes to an external fiber or waveguide.  The laser includes an active gain region disposed in a laser cavity that is formed in a semiconductor material.  A lens and a waveguide are also located in the laser cavity.  The lens receives optical energy generated by the active gain region and directs this energy into one end of the waveguide.  The waveguide transmits the optical energy from the laser to an external fiber or waveguide.   The waveguide may be either a single mode waveguide or a multimode waveguide that selects a predetermined number of modes from among all the modes generated by the active region.  If a single mode waveguide is employed, the output energy is composed of the fundamental frequency generated by the active region. If a multimode waveguide is employed, the output energy is composed of the predetermined modes selected by the waveguide.

Abstract: In a display system suitable for high ambient light environments, a lamp is used simply as a light source to illuminate a rear projection display screen, which is a matrix of tiny cells that modulate the light at video rates.   Each cell  includes a polymer dispersed liquid crystal (PDLC), a focusing lens and a pinhole aperture. When the PDLC is electrically activated,  light passing through the PDLC is scattered in many directions, and very little light passes through the pinhole aperture and is seen by the viewer.   When the PDLC is not electrically activated, light passing through the PDLC is not scattered, the lens of each cell focuses the light through the pinhole aperture, and the viewer sees a bright spot of light.

Title: A windtrap for power development
Inventor: WHELAN MATTHEW P
IPC: F03D80/00
Filed: 1995-09-25
Granted: 1999-05-25
Abstract: This invention relates to windpower and is titled "A Windtrap For Power Development". It is designed to take power from the wind by turning a vertical mast. The intention is to hold the total wind force that comes within the dimensional area of each unit when the said unit comes to the power side, then have the trap automatically close and feather the wind on the return side of the revolving mast. Feathering on the return side is assisted by:   a) a cable from a wing arm to the top side frame of the trap to hold same horizontal when on the return side, and b) two torsion springs on each unit attached, one to each end of the lower side frame of trap. The springs must carry 60% to 70 % of weight of the lower trap side section. Torsion helps wind lift the lower side towards the horizontal on the return side of mast and leaves 30% to 40% of the weight so gravity cam open it again on the power side. A partial balance is set by the torsion springs, between gravity, the trap design and wind force, to give continuous opening and closing, with the trap holding full wind force on power side and giving minimum resistance on return side.

Title: Apparatus for forming sheets of material having a uniform thickness and cutting individual portions therefrom
Inventor: OUELLETTE EDWARD L
IPC: A21C3/10
Filed: 1995-08-09
Granted: 2001-04-03
Abstract: An apparatus for forming a sheet of material, e.g., dough or masa, from a supply of the material includes a pair of rotatable rollers that define therebetween a gap into which is input a dough mass and out of which is produced a dough sheet. Fluctuations in the size of the roller gap are sensed by detecting changes in the position of one of the rollers, which changes are input to a servo system that automatically corrects the position of the one roller so as to maintain the proper gap size. The one roller is movably mounted in scissor-like fashion and is easily driven by a servo motor. A  cutter is provided which presses against one of the rollers to cut individual dough portions from the sheet. The ends of the cutter are subjected to a bending moment which induces a camber in the cutter. This prevents the central portion of the cutter from bowing away from the roller and ensures uniform pressure between the cutter and roller, even for applications with an extremely long cutter and rollers.

Abstract: A method for the abatement of contaminant-laden process emissions produced by various wood manufacturing processes comprises the step of flowing the emissions through an oxidation catalyst (114, 116, or 118) located in a regenerative catalytic oxidizer (100) to remove volatile organic compounds (VOC's), methanol, formaldehyde, resins, binders, and hazardous air pollutants (HAP's) at lower peak temperatures than the temperatures encountered in regenerative thermal oxidizers. The oxidation catalyst allows the overall abatement process to operate at lower peak combustion temperatures. By reducing the peak combustion temperatures during the abatement of emissions, the present invention precludes potassium and/or sodium in the emissions from reacting with silica in the heat recovery media and ceramic fiber insulation of the regenerative thermal oxidizer. This reaction has heretofore destroyed the desired properties of the wood product and compromised the quality of te product.

Abstract: Cette invention concerne un procédé permettant de traiter un signal modulé par des symboles d'information pour compenser un décalage et une pente supplémentaires. On effectue tout d'abord une estimation initiale du décalage et de la pente puis on prend des hypothèses correspondant à toutes les valeurs possibles d'une séquence constituée d'au moins un symbole d'information. Pour chacune de ces hypothèses, on utilise la séquence associée de symboles de données pour obtenir une meilleure estimation du décalage et de la pente, et l'on stocke l'estimation améliorée du décalage et de la pente. Pour chacune de ces hypothèses, on utilise l'estimation améliorée du décalage et de la pente pour calculer une valeur estimée du signal et l'on calcule la différence entre un échantillon du signal modulé et cette valeur estimée. On procède ensuite à une extension de ces hypothèses d'un symbole, on actualise les estimations du décalage et de la pente, on cumule les différences de façon à obtenir une valeur métrique de voie pour chaque hypothèse étendue, et l'on effectue une résolution entre lesdites hypothèses en fonction desdites valeurs métriques de voie au moyen d'un procédé séquentiel de Viterbi d'estimation des séquences de probabilité maximale dans le but d'obtenir l'hypothèse la plus probable desdits symboles d'information modulés, pratiquement non altérés par le décalage et la pente supplémentaires.
