Title: Parameter value communication system
Inventor: MOORE LEONARD W
IPC: G08C15/00

Granted: 1992-06-09
Abstract: Abstract of the Disclosure A multipoint communications system for transmitting the values of a multiplicity of analog parameters from one point digitally to another point and reconverting then into analog parameters.  The system includes a plurality of input modules which  communicate  with  respective  output  modules  over  a communications link.  The input and output modules are configured similarly  with  a  control  processor  connected  to either multiplexing circuitry,  in the case of an input module,  or demultiplexing circuitry in the case of an output module.  The multiplexing  circuitry  is connected  to  a  plurality  of configurable input circuits which receive the values of the various measured conditions or parameters.  The demultiplexing circuitry is connected to a plurality of configurable output circuits  which  output  the  values  of  the various  measured conditions or parameters.  In a preferred protocol, a link master is chosen from among the input modules to generate a polling sequence  for the  input-output module pairs.   A poll  of a particular module is taken by generating a wake-up message, which the  module responds to with a ready message.   When a ready message is received, the link master generates a go-ahead signal and  becomes  dormant  for  a  time  period  before  continuing.     Otherwise, if a ready message is not received, the poll will continue.  When a module has authority to communicate, it wakes-up its corresponding output module, which responds with a ready message.   When the selected input module receives a  ready message,  it transmits a plurality of stored digital values corresponding to the analog parameters which were input.  The system includes a communications mode where the values are transmitted, a calibration mode where the range of input and output values are set for each module, a configuration mode where each module is assigned an address and each input and output matched and configured.  An input can be configured for voltage, current, TTL, or contact closure inputs and an output configured to output voltage, current, TTL, or contact closure.

Spaced apart sequences of fluid quanta are injected into the output conduit from the fluid flow junction.  The fluids are either mixed, or not, in the output conduit as desired.  Operator interaction and control of the system can occur either through a display screen or by means of a bar code sensor.  Hard copy records can be provided of fluid flow delivery schedules or other related information.

Abstract: A construction module is described, one side of which has four slightly resilient spring leaves (6, 6') which are arranged in a tulip shape and can easily snap onto the other five side faces (2 to 5) of an identical construction module. The side faces have strips (8, 8') which can be continuous or interrupted. On the inside, the spring leaves are provided with corresponding connecting elements (7, 7', 7'') which engage behind the said strips. A connection is produced between two construction modules firstly by slight deflection of the spring leaves from their position of rest and by subsequent engagement behind the said strips. The construction modules have the advantage that they can be connected to one another or detached from one another easily and reliably even after a long time and frequent use. <IMAGE>

Abstract: The invention concerns the synthesis of methanol from lower hydrocarbons. The C1-3 hydrocarbons are subjected to partial oxidation over a catalyst in the presence of oxygen and steam, part of the carbon dioxide is removed from the effluent gas to adjust the ratio of hydrogen to carbon monoxide and carbon dioxide, and the resulting gas is converted to methanol in a steam generating reactor. The over all economy of the process is clearly better than that of conventional processes utilising a steam reformer.

Abstract: A hydraulic door opening or closing device comprises a hydraulic fluid pump motor (7) having two ports connected to each end of integral dual manifold (8, 9) and operating cylinder apparatus (10) by way of two branch fluid lines (11, 12). One branch line is fluidly connected to a particular end of the operating cylinder by way of a directional flow valve (17, 18). The other branch line to the same end of the cylinder is fluidly connected to the cylinder by way of an associated manifold (8, 9). Fluid communication with the cylinder through the manifold (8, 9) is accomplished by providing a plurality of valved openings (21-30) linearly disposed along the end of the cylinder between the manifold (8, 9) and the cylinder (10). As a piston (14) of the operating cylinder (10) passes these openings, a door coupled to the piston (14) is automatically slowed as fluid on the drive side of the piston is returned through the openings to the hydraulic fluid pump (7). A simplified control circuit coupled to the device provides three modes of operation, an opening mode, a closing mode and a reversing mode from door opening to door closing.

Abstract: A polymer composition usable for the production of articles of biodegradable plastics material includes an ethylene/vinyl alcohol copolymer and destructured starch. Preferably, the composition is obtainable by mixing the ethylene/vinyl alcohol copolymer, in a heated extruder, with a starch component constituted by a destructured starch composition produced beforehand by mixing starch with a high-boiling plasticizer, such as glycerine and a destructuring agent, preferably constituted by urea, in an extruder. Alternatively, the composition can be obtained by mixing the ethylene/vinyl alcohol copolymer with starch and a plasticizer in an extruder, with water added as appropriate and possibly with a suitable destructuring agent. The composition is particularly useful for the production of films with good resistance to perforation and tearing and moulded articles with improved mechanical strength. The products made from this composition are also good oxygen and carbon dioxide barriers.

Abstract: A process and apparatus for melting contaminated metalliferous scrap material are disclosed. The process comprises introducing the contaminated material (11, 72) into a melting furnace (12, 70), heating the material by means of a plasma (13, 71) at a temperature below the melting point of the metal at which the non-metallic contaminants are volatilized in an atmosphere which is preferably inert or has low reactivity with the metal under the process conditions while displacing at least some of the material (11, 72) within the furnace interior, withdrawing volatile contaminants from the furnace (12, 70), increasing the temperature in the furnace preferably while maintaining an atmosphere of low reactivity in the furnace in order to melt the metal while preferably displacing at least some of the material in the furnace interior, and removing molten metal (77) from the furnace. The process allows scrap material to be melted with good metal recovery without the need for separate decontaminating apparatus. The process can also avoid the need to shred the scrap and to add large amounts of fluxing salts to separate the molten metal from remaining dross. A rotary furnace (12, 70) heated by means of a contained arc plasma torch (13, 71) is preferably employed in the apparatus which also preferably comprises an incinerator (21, 79) for oxidizing the volatile contaminants withdrawn from the furnace.

Abstract: A metal-encapsulated and gas-insulated load switching device has a three-position switch (4) for the 'on', 'off' and 'earthed' positions and a vacuum power switch. Here, with the three-position switch (4) in its 'on' position, there is a series connection with the vacuum power switch (11) such that the three-position switch (4) is connected to the busbar side and the vacuum power switch (11) to the output side. The output side is directly earthed with the three-position switch (4) in the 'earthed' position. In this circuit, short-circuit currents are contolled without any additional interlocks as there is a three-position switch designed as a load separating and earthing switch which is also capable of switch-on on a short circuit. The space provided for the vacuum switching tubes (12) can be of such a size that fuse chambers can also be used for HCBC fuse inserts. It is thus possible to create modular units of the same size with different switchgear for the most common switching purposes.
