When the closeable conduit is closed an endless circulating path is formed between the container and the hopper to charge the container with abrasive from the hopper and carrier mixture. The mixture is conveyed under pressure from the container to the nozzle when the inlet and outlet conduits from the hopper to the container are disconnected and the closeable conduit is open.

Abstract: The modular tanker or other ship building involves bottom sections, intermediate decks, upper deck, and sides, which are all interconnected at the assembly station. To separate the deck and bottom outfitting operations and associated subassembly work from the main modular assembly station, the upper deck (1) section is raised at the assembly station above the first mid deck level. This deck (2) is then raised below, and connected to, the upper deck, followed by the second mid deck (3) below, and connected, to these. - After these three sections have been assembled, a bottom section (4) is installed and connected to the assembly, followed in turn by the side sections (5,6) to complete the module. Alternatively, the sides can be fitted before the bottom section. When fitting, one side (5) is fitted first and the assembly then swivelled round its vertical axis of symmetry and the second side

Abstract: In accordance with the invention a chemimechanical pulp is produced from lignocellulosic material, for example wood chips, by subjecting the material to a process in which it is steamed, impregnated with alkali and peroxide, drained, pre-heated, refined and bleached.The material is impregnated in a single stage with solution containing alkali and peroxide. Subsequent to passing an intermediate drainage and reaction stage, the material is pre-heated to a temperature of from about 50°C, but not above 100°C. The material is then refined in one or two stages.The material can be impregnated by immersing the same in the impregnating solution for a period of up to 20 minutes at a temperature of 15-60°C, or by compressing the material in a screw press and permitting the compressed material to expand in the impregnating solution.The ratio of alkali to peroxide in the impregnating solution is balanced so as to obtain a pH greater than 12.The optimal brightness for a given peroxide charge is achieved by a balanced division of the peroxide charge between the chip impregnating stage and the bleaching stage.

Abstract: A system and method for providing computerized, knowledge-based medical diagnostic and treatment advice. The medical advice is provided to the general public over networks, such as a telephone network or a computer network. The invention also includes a stand-alone embodiment that may utilize occasional connectivity to a central computer by use of a network, such as the Internet. Two new authoring languages, interactive voice response and speech recognition are used to enable expert and general practitioner knowledge to be encoded for access by the public. "Meta" functions for time-density analysis of a number of factors regarding the number of medical complaints per unit of time are an integral part of the system. A re-enter feature monitors the user's changing condition over time. A sympton severity analysis helps to respond to the changing conditions. System sensitivity factors may be changed at a global level or other levels to adjust the system advice as necessary.

Title: Method and apparatus for controlling single or multiphase a.c. power controllers
Inventor: RUNGGALDIER DIETHARD
IPC: H02P27/02
Filed: 1990-02-05
Granted: 1999-01-26
Abstract: In the control of a.c. power controllers by the phase-angle control of semiconductor valves that are used to automatically control the power factor, it is necessary to determine the phase-angle between the current I and the voltage U by measuring the time difference between the current zero crossing and the voltage zero crossing.  However, disturbances superimposed on the line voltage produce considerable statistical fluctuations, particularly in the measurement of the times for the voltage zero crossings.  These fluctuations are propagated to the phase-angle and may lead to an unstable control response.  Therefore, to determine the time difference, a reference time, which is calculated from the measured actual times of the preceding voltage zero crossings, is used for the voltage zero crossing.

Granted: 1995-01-17
Abstract: A telecine scanner is selectively conformed to evaluate the dye densities characteristic of either negative or print film.  The film (10) is interposed in a light path (12) between a light source (14) and a pickup stage (16) that develops a plurality of color output signals from the light passing through the film.  Color channel filters (38, 40, 42) included in the pickup stage have spectral passbands in the respective colors that are broad enough to include the spectral dye densities of both negative and print materials.  The scanner sensitivity is further limited to a particular film material by inserting an appropriate shaping filter set (44, 45) into the light path, preferably between the light source and the film, for conforming the peak sensitivity of at least one of the passbands to the peak spectral density of the corresponding dye of the particular film material.

Abstract: A multi-stage rotary type compressor is constituted in such a manner that an electric motor and a plurality of compression elements to be driven by the electric motor are disposed in a closed container and the compression elements thus-disposed are sequentially connected in series. The compressor thus-constituted is arranged in such a manner that the space in the closed container is filled with the pressure discharged from the final stage. Furthermore, lubricating oil, the pressure of which is equivalent to the level of the pressure discharged from each compression element, is introduced into a back side chamber of a vane of each compression element to urge the back side of each vane with the pressure of lubricating oil. As a result, the wear of the tip end of the vane and the input loss are prevented. Therefore, satisfactory durability and compression efficiency can be obtained.
