Abstract: Method for production of magnesium chloride, to be used for production of magnesium, by leaching of magnesite in hydro-chloric acid. A two-stage leaching process is used where in the first stage coarsly crushed magnesite lumps are dissolved by feeding hydrochloric acid. The reaction solution from the first stage is led to a second stage, where finely ground magnesite or hydrochloric acid is added to obtain approximate equivalence between magnesium and chlorine. To precipitate the impurities an excess of magnesium oxide or magnesium hydroxide is added in one or several purification stages.

Title: Method for entering digit sequences by voice command
Inventor: GERSON IRA A
IPC: G10L15/00

Granted: 1993-01-12
Abstract: ABSTRACT OF THE DISCLOSURE             A user-interactive speech recognition control system is disclosed for recognizing a complete sequence of keywords (e.g., a telephone number such as 123-4567) via entering, verifying, and editing variable-length utterance strings (e.g., 1-2-3; 4-5; 6-7) separated by the user-defined placement of pauses.  The device controller (120) utilizes timers (124) to monitor the pause time between partial-sequence digit strings recognized by the speech recognizer (110).  When a string of digits is followed by a predetermined pause time interval, the recognized digits will be replied via the speech synthesizer (130). An additional string of digits can then be entered, and only the subsequent string will be replied after the next pause.  Furthermore, the user has the flexibility to correct only the last digit string entered, or the entire sequence.  Hence, if there is an error in only one digit, the erroneous digit string can be corrected without having to re-enter the entire digit sequence.  The invention is well-suited to be used in a hands-free voice command dialing system for a mobile radiotelephone, wherein vehicular background noise may affect recognition accuracy.

Title: Method and system for high-speed, high-resolution, 3-d imaging of an object at a vision station

Abstract: METHOD SND SYSTEM FOR HIGH-SPEED, OF AN OBJECT AT A VISION STATION                    ABSTRACT A method and system for high-speed,  high-resolution,  3-D imaging of an object at a vision station  including an anamorphic magnification and field lens system to deliver the light reflected from the object to a small area position detector having a position-sensing direction.   Preferably, an acousto-optic deflector having no moving parts together with associated lens elements scans a beam of modulated laser light in a scanning direction across  the  object to be  inspected to produce  a telecentric, flat field scan.   The deflector has a feedback loop to enable uniform illumination of the object  (i.e.  flat field  correction).  The  light scattered  from  the  object  is  collected  by  a telecentric receiver lens,   A combined spatial and polarization filtering plane preferably in the form of a programmable mask is provided, as a telecentric stop  to  control  the polarization  and  acceptance angles of the collected light.  A focusing lens is positioned immediately behind the filtering plane and is utilized as a telescope objective.  The lens system includes a negative cylinder lens having a relatively  large  focal  length  and  an  anamorphic field lens having a relatively small focal length. The cylinder lens and the reduction lens magnify the image  in  the  position  sensing  direction  of  the position detector and the field lens delivers the light  to  the  position  detector.    The position detector is a photodetector such as a lateral effect photodiode or a rectangular lateral effect detector together with its pre-amplifier. The pre-amplifier provides  a pair of  electrical  signals which are utilized by signal processing circuitry to compute the position of the centroid of the light spot.  To extend the depth of range, a controller is coupled to  the  signal  processing  circuitry  and  controls movement  of  a tracking mirror which,  in affect, enlarges the field of view of the position detector.

Abstract: At least three control patterns are used for a connection management control of nodes in a ring network, each node determining a changeable communica-tion status in accordance with a communication status of the own node and the nature of the control pattern received from an upstream node. The own node transmits one of the control patterns, selected in accordance with the changes in the communication status, to the downstream node. The control patterns indicate respec-tive conditions of the own node so that the communica-tion enable status of the ring network, as a whole, can be autonomously established by the nodes per se without employing a monitor node or supervisory node.

Abstract: CONTROL OF PRODUCT SELECTIVITY IN THE      ADDITION OF HCN TO ARABINOSE                              ABSTRACT Hydrogen cyanide addition to a monosaccharide results in a mixture of product cyanohydrins whose ratio can be changed by conducting the hydrogen cyanide addition in the presence of an agent which  forms  a complex with  the monosaccharide.    It  is preferred to add the elements of hydrogen cyanide to a preformed complex of the monosaccharide.  The product selectivity appears to be dependent upon the concentration of the complexing agent up to about  one  molar  proportion  of  the  latter  relative  to  the monosaccharide with the selectivity being invariant thereafter.

Abstract: ELECTRONIC FILTERS, HEARING AIDS AND METHODS            Abstract An electronic filter for an electroacoustic sys-tem.  The system has a microphone for generating an elec-trical output from external sounds and an electrically driven transducer for emitting sound.  Some of the sound emitted by the transducer returns to the microphone means to add a feedback contribution to its electrical output. The electronic filter includes a first circuit for elec-tronic processing of the electrical output of the micro-phone to produce a filtered signal.  An adaptive filter, interconnected with the first circuit, performs electronic processing of the filtered signal to produce an adaptive output to the first circuit to substantially offset the feedback contribution in the electrical output of the microphone, and the adaptive filter includes means for adapting only in response to polarities of signals supplied to and from the first circuit.  Other electronic filters for hearing aids, public address systems and other electro-acoustic systems, as well as such systems and methods of operating them are also disclosed.

Abstract: Abstract of the Disclosure A local area network for interconnecting terminals and other users and data processing systems and other service providers over a communications link.  The users and providers connect to the communications link by means of interface units each of which may connect to several users or providers.  The interface units communicate over the communications link by means of messages.  When a user requires the use of a service, the interface unit establishes a virtual circuit between it and the interface unit connected to the service provider and a service session which allows the user and the service provider to communicate over the virtual circuit.  If-several users connected to the one interface unit as the first user require services provided by providers which connected to the same interface unit as the first provider, they communicate in sessions over the same virtual circuits.  The session messages are accumulated into single virtual circuit messages that are acknowledged in unison by the receiving interface unit. Each virtual circuit in the users' interface units includes a timer which reset when a message is transmitted over the virtual circuit and a data waiting flag set whenever data is present to be transitted over the virtual circuit.  The interface units are inhibited from transmitting over a virtual circuit unless the timer has timed out and the data waiting flag is set.
