IPC: H04Q3/62
Filed: 1987-09-30
Granted: 1991-03-05
Abstract: COMMUNICATION SYSTEM HAVING AUTOMATIC CALL ROUTE SELECTION            Abstract An automatic route selection capability for a communication system is described which enables the system to utilize digits of a called party number to select in a predetermined manner a predefined group of line pools and a line therein over which the call is to be placed. Once the predefined group of line pools is selected, a priority scheme enables the system to sequentially search each line pool for an available line over which the call can be placed. The system dials the called party using route character digits which prepend or optionally replace one or more of the user-dialed digits.

Abstract: The invention relates to a process for the separation of granulate materials, in extruded form of different lengths and of the same or different diameter. It is characterized by the use of a helicoidal vibrating elevator subjected to vibrations whose amplitude is chosen so as to cause on the threads of the spiral on the one hand the ascending flow of all the particles and on the other hand the recovery of the finest particles on the outer edge of the upper thread of the spiral and the largest particles on the inner edge of the upper thread of this spiral.

Title: Chipper
Inventor: VUOLLET MARTTI
IPC: B27L11/02
Filed: 1988-01-05
Granted: 1993-03-09
Abstract: ABSTRACT     Chipper for chipping of wood into chips suitable for defibrizing.  The basic construction of the chipper consists of a horizontal shaft supported by a frame structure as well as of a blade disc mounted on the shaft in a vertical plane.  The blade that performs the chipping is mounted on one side of the blade disc or, alternatively, on both vertical side faces of the disc.          The blade projects from the side face of the blade disc perpendicularly and runs on the side face of the blade disc as a continuous narrowing spiral starting from the periphery of the blade disc.  As the cutting edge of the blade becomes more distant from the periphery of the blade disc, it simultaneously also becomes more distant from the plane of the blade disc while following a screw line.  The length of the chips to be chipped is determined by the spiral pitch of the blade edge, i.e. by the relative distance between two radial points on the blade edge.          For the purpose of determining the chip thickness, on the chipper blade, cutting teeth directed towards the shaft have been placed one after the other as uniformly spaced, the front edge of the said teeth being sharpened.

Said gaseous mixture (1), after having eventually undergone an operation of removal of benzol (25) and then cooling (2) producing condensates (4), is washed between 0 DEG  C. and -45 DEG C. by means of a solvent (5) selective of H2S to produce a current of methane (64) having a partial pressure in H2S below 65 Pa and a liquid phase (9a) rich in H2S and containing at least 80% molar of the hydrocarbons of C3 and more of the gaseous mixture (1). The liquid phase (9a) is subjected to a demethanization (29, 9) producing a demethanized rich solvent (11) and a gaseous phase rich in methane (10), the solvent (11) then is cooled between -25 DEG  and -80 DEG C. sufficiently to produce its dissociation in a lower liquid fraction (38) that contains the H2S and, in methane equivalent, less than 5% molar of hydrocarbons and an upper liquid fraction (37) formed of the hydrocarbons of C3 and more. Said fractions (37, 38)are separated and the fraction (38) undergoes a regeneration (46, 16, 20) to produce a current (24) of acid gas rich in H2S and containing the small amount cited above of hydrocarbons and a regenerated solvent (21).

Title: Memory organization and output sequencer for a signal processor
Inventor: VEA MATTHEW J J
IPC: H04Q1/457
Filed: 1988-09-21
Granted: 1991-08-20
Abstract: ABSTRACT       A specialized tone receiver is capable of detecting tones on many different digital signal channels simultanously.  A single memory is used to buffer incoming digital signals  Independent write and read sequencers write samples into and read samples from the buffer memory, respectively.  The write sequencer writes all samples corresponding to a given sample time at essentially the same time, while the read sequencer reads out all of the samples corresponding to a given channel of interest in reverse sequential chronological order (i.e., in the opposite order from the order the samples were written) beginning with the most current sample.  A priority structure controls access to the buffer memory, with the read sequencer being granted a higher access priority than the write sequencer.  A filtering algorithm symmetrical in time and executed by a digital signal processor controlled by the same microcode sequencer which controls the read sequencer is used to detect specific frequencies present in the read channel samples.  A separate, slower processor performs time validation functions on a time scale which is extremely slow compared with the time scale at which frequency validation is performed.  The specialized tone receiver is extremely fast, requires only a single, relatively small input buffer memory (e.g., 128 Kbytes for a 512 channel PCM bus), and is capable of detecting several different specialized signalling tones on all of the channels of a multiport multichannel PCM bus in very close to real time.

A combustor (12) is formed with cooled walls (14) which form a feed water preheater,  A by-pass conduit (104) with a control valve (106) for draining feed water is connec-ted to a feed water conduit (82) between the feed water preheater (the combustor walls (14)) and an evaporator (66) in the com-bustor (12).  This by-pass conduit (104) may be connected to a feed water tank (74).

Granted: 1993-04-13
Abstract: EXCITATION SUPPLY FOR GAS DISCHARGE TUBES               Abstract of the Disclosure The present invention uses a variable fre-quency oscillator to drive a primary resonant converter output transformer circuit for exciting gas discharge tubes.  The combination of the impedance of the reso-nant conversion circuit along with the impedance of the driven gas discharge tube taken in combination with the frequency of the variable oscillator will determine the output voltage of the circuit.  By varying the fre-quency of the oscillator, the optimal ouput voltage and hence the optimal brightness of the gas discharge tube may be selected.  At the optimal output voltage, the frequency of the switching supply may create an unde-sirable or desirable "bubble effect" in the gas discharge tube.  An optional secondary frequency may be combined with the frequency of the variable frequency oscillator to create or eliminate the bubble effect according to the esthetic desires of the user.

A plurality of clusters of pixels, each representing a printed character, are identified.  A pixel in one cluster is selected, and its neighborhood state determined.  The neighborhood state is used to address a memory that has stored in it a probability table providing the probability, in a second font different from the new font being taught, that a pixel is black as a function of its neighborhood state.  The stored probability of black associated with the neighborhood state of the select pixel is read from the memory and assigned as the probability of the selected pixel.  The decision tree for the new font is generated using that assigned probability of black.
