Inventor: MAHAGAOKAR UDAY
IPC: C10K1/20
Filed: 1994-11-08
Abstract: A method for reducing the hydrogen halide(s) content of a synthesis gas stream by gasifying a carbonaceous feed material in a gasifier to produce a gas/solids mixture of hydrogen, carbon monoxide, hydrogen halide gas, and fly slag particles; passing the gas/solids mixture to a solids removal zone where at least a portion of the fly slag particles are removed, to produce a gas stream; admixing with the said gas stream an alkali metal oxide, hydroxide, bicarbonate, or carbonate to produce an alkali metal compound/gas mixture; passing the alkali metal compound/gas mixture to a means for increasing the contact time between said hydrogen halide(s) and said alkali metal compound(s) or their thermal docomposition products; reacting the alkali metal compound(s) with the said hydrogen halide(s) to produce solid alkali metal halide(s); and recovering a gas stream substantially free of hydrogen halide(s) and solids.

IPC: H04N7/173
Filed: 1996-08-30
Abstract: A bidirectional cable network having a signal distribution system that prevents undesirable energy in the bidirectional cable network's return path from adversely effecting the entire network.

Signals transmitted in a return path direction are time division multiplexed on a series of cyclically reoccurring time slots where at least one of the cyclically reoccurring time slots is assigned to each of the plurality of remote points.  At least one primary is effective during each occurrence of the cyclically reoccurring time slots for isolating all of the plurality of remote points from accessing the network to transmit a signal in the second direction except for one of the plurality of remote points which is assigned the cyclically reoccurring time slot that is presently providing a path to transmit in the second direction from the remote point to the headend. In one embodiment each return gate services a plurality of remote points within the return gate's distribution branch. In a second embodiment each remote point has a dedicated return gate.

Title: Subscriber authentication for radio local loop system
Inventor: GORDON MALCOLM
IPC: H04W12/06
Filed: 1997-02-28
Abstract: The network security of a radio local loop system is highly desirable to avoid fraudulent use of the network by unauthorised users with appropriate subscriber equipment. For fixed subscribers, the propagation delay between base station (1) and subscriber unit (3) will also remain fixed and, provided this is measured with sufficient accuracy, the distance from the subscriber to the base station can bedetermined. This can be used as an aid to the authentication of a subscriber. Other signal characteristics which are indicative of the physical location of a purported subscriber can be used, such as directional information. In a system in which propagation delay has to be monitored anyway, for other purposes, such as orthogonal CDMA code synchronisation, or for a TDM system, added security can be obtained without great extra cost.

Abstract: Affichage à cristaux liquides à matrice active utilisant une échelle de gris en demi-teintes, possédant des domaines multiples et utilisant une configuration à espace unique, afin de réaliser économiquement un angle de visualisation très large. Le substrat de l'affichage possède des zones comportant une pente ou un alignement de sens différents à partir du sens de la pente ou de l'alignement dans d'autres zones contiguës. Chaque pixel de la matrice d'échelle de gris possède une pluralité de sous-pixels, de telle manière que chaque sous-pixel se met en fonction à une tension différente de celle des autres sous-pixels. Les zones comprenant différentes pentes ou différents alignements sur les substrats peuvent être des zones de pixels ou de sous-pixels. Au moins une couche de retard de compensation se trouve sur l'affichage. La technique mettant en application la combinaison de domaines multiples et de compensation par des pixels d'échelle de gris en demi-teintes permet d'obtenir un affichage possédant des angles de visualisation considérablement plus importants qu'un affichage à domaines multiples ou un affichage à échelle de gris en demi-teintes, à compensation ou sans compensation.

Title: Improved dough divider
Inventor: WILLETT PAUL EATON
IPC: A21C5/02
Filed: 1996-04-19
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).
