Title: Person and object recognition system
Inventor: FREY RONALD G
IPC: G06Q10/06
Filed: 1992-03-30
Granted: 2001-02-06
Abstract: A system for automatically recognizing persons or objects as they move past a selected location and for classifying the persons or objects in accordance with selected criteria. The system includes emitters for emitting beams toward a person or object moving past a selected location to generate reflected beams from the person or object. The included angle of the emitted and reflected beam is a function of the height of the person or object. A detector detects the reflected beams and generates signals representative of the included angle, and thus representative of a time-dependent height profile of the person or object from which the beams are reflected. The person or object is classified according to selected criteria.

Title: Method for the sheeting of deep trenches
Inventor: HESS WILHELM
IPC: E02D5/02
Filed: 1992-04-07
Granted: 2003-10-21
Abstract: A method for sheeting deep trenches by means of supporting frames mountable lengthwise the trench at equal distances. The supporting frames comprise two parallel supporting elements and a rigid frame movable in the longitudinal direction of the supporting elements and connecting and keeping them spaced-apart, and large sheeting panels insertable into guide channels of the supporting elements. The supporting frames and the sheeting panels are pressed or lowered into the trench, following the direction of excavation. The rigid frame is movably guided between a lower stop and an upper stop along the supporting elements, whereby the lower stop is positioned at the required shovel clearance approximately 1 to 1.50 m from the end of the supporting element, and the upper stop is positioned at a distance from the lower stop, which distance corresponds to the height of the rigid frame, e.g., 1.75 m, and to an admissible support advance, e.g., 0.5 m. Once the supporting frame has been installed and lowered to a level at which the upper edge of the rigid frame is on the level of the trench's edge, the upper stops are removed, a second rigid frame is inserted into the supporting elements of the supporting frame, and the upper stops are fastened to the supporting elements at a distance above the second rigid frame. After lowering the supporting frame by another depth equal to a rigid frame, the upper stops are removed and, if necessary, a third rigid frame is inserted into the supporting elements of the supporting frame. The rigid frames are interconnected with each other to permit dismantling of the supporting frame.

Title: Method for producing hydrochloromethanes
Inventor: MORIKAWA SHINSUKE
IPC: C07C17/00
Filed: 1992-04-23
Granted: 1999-05-11
Abstract: A process for producing hydrochloromethanes such as chloroform at high selectivi ty in high yields by reducing polychloromethanes such as carbon tetrachloride in the presence of a reduction catalyst. It is esse ntial to conduct reduction in liquid phase so as to inhibit effectively the concomitant formation of impurities such as a p olymer which deactivates the catalyst, whereby the catalyst can fully develop its high selectivity and activity. As the catalyst, a t least one element is suitably selected among the group 8, 9 and 10 elements of the Periodic Table, such as ruthenium, rhodium, palladiu m or platinum. Also suitably usable is a catalyst which is based on any of the above elements and further contains at least one of the group 11 elements such as copper, silver or gold. When the liquid-phase reduction is to be conducted continuously, the use o f a fixed bed is desirable, a dropping bed being particularly desirable. This process is also highly valuable as a process for co nverting carbon tetrachloride, the use of which is legally regulated from the viewpoint of the preservation of the global environme nt, into, for example, chloroform, which is useful as the starting material of various fluorine compounds.

Title: Partial oxidation process for producing a stream of hot purified gas
Inventor: LEININGER THOMAS FREDERICK
IPC: C01B3/36
Filed: 1994-05-24
Granted: 2005-03-29
Abstract: A partial oxidation process for the production of a stream of hot clean gas substantially free from particulate matter, alkali metal compounds, hydrogen halides, hydrogen cyanide, sulfur-containing gases, and with or without ammonia for use as synthesis gas, reducing gas, or fuel gas. A pumpable hydrocarbonaceous fuel selected from the group consisting of liquid hydrocarbonaceous fuel or liquid emulsions thereof, an aqueous slurry of petroleum coke, and mixtures thereof and wherein said hydrocarbonaceous fuel contains halides, alkali metal compounds, sulfur, nitrogen and inorganic ash containing components, is reacted in a gasifier by partial oxidation to produce a hot raw gas stream comprising H2, CO, CO2, H2O, CH4, NH3, HCN, HCl, HF, H2S, COS, N2, Ar, particulate matter, vapor phase alkali metal compounds, and molten slag. The hot raw gas stream from the gasifier is cooled in a radiant cooler and cleaned. Optionally, ammonia is removed from the gas stream by being catalytically disproportionated into N2 and H2. The process gas stream is cooled and halides and HCN in the gas stream are reacted with a supplementary alkali metal compound to remove HCl, HF and HCN. Alkali metal halides and alkali metal cyanide, vaporized alkali metal compounds and residual fine particulate matter are removed from the gas stream by further cooling and filtering. The sulfur-containing gases in the process gas stream are then reacted at high temperature with a regenerable sulfur-reactive mixed metal oxide sulfur sorbent material to produce a sulfided sorbent material which is then separated from the hot clean purified gas stream having a temperature of at least 1000°F.

Title: Structured image (si) format for describing complex color raster images
Inventor: VENABLE DENNIS L
IPC: G06T11/60
Filed: 1994-09-02
Granted: 2001-05-29
Abstract: A means and method of describing a complex color raster image as a collection of objects in a hierarchical and device independent format.      The purpose of structured imaging (SI) is to expand the scope of a raster image to a collection of individually manipulable component objects. An SI is a hierarchical description of a single output image raster which may be used as one component of a page in a structured document. Objects contributing to the output raster may originate from text, graphics, other rasters or a combination thereof, and all maintain their heritage for selectability and modification. The SI describes not only the source data but also the image processing operations required for rendering the output raster. SI technology supports re-editability, customization and enhancement, automatic image assembly and high performance imaging.  Thus, such a model has implications not only in an image editing and processing arena, but also in the filing and printing services used for image handling.

Title: Method and apparatus for supplying synchronization signals serving as clock signals with defined phase relationships
Inventor: PITIO WALTER MICHAEL
IPC: H04L7/08
Filed: 1994-12-20
Granted: 1999-12-21
Abstract: The present invention relates to a method and apparatus for recovering the time base of signals which change at periodic intervals. The apparatus comprises gated voltage controlled oscillators (GVOC) that are alternated or exchanged, to reduce phase and frequency deviations in the recovered time base signal, such as the deviations induced by inherent GVCO differences. Each GVCO is stabilized by a respective phase locked loop. The respective GVCOs are gated only in response to a chosen polarity transition in the input signal, to make the circuit more tolerant of waveform distortions. More than two GVCOs may be used to provide improved frequency drift resistance. The circuit uses resynchronization control signals, such as the time slot signal in synchronous switching systems, to indicate resynchronization or reassignment the GVCOs in gaps in the data transmission. Automatic reassignment is insured when there are periods of non-transitioning data that last longer then the stability of the GVCOs to prevent frequency drift in the recovered clock.
