Abstract: INTERACTIVE ROOM STATUS/TIME INFORMATION SYSTEM            ABSTRACT OF THE DISCLOSURE      An interactive room status/time information system is pro-vided having a terminal associated with a television comprising a pro-cessor for processing data, an associated memory for storing opera-tion data and control algorithms, a keypad with remote control for inputting information, a character generator responsive to the pro-cessor for generating a multiple character, multiple line display, a power supply input, and a cable transmission link for communication at television frequencies with a system manager. A maid or inspector can send status information from a hotel/hospital room terminal over a cable television system to a system manager location. The status of a room for occupancy is determined by a two-step procedure. Input from both a maid and an inspector must be received before a room has a ready-for-occupancy status. Screens of compiled room status and historical data can be displayed at the system manager. Also, certain screens of room status data may be displayed on an associated television at the room terminal. Functions can be performed at the system manager location including searching stored status informa-tion for historical data of a particular room or maid. In accordance with a further time control feature of the present system, a hotel guest may actuate a wake-up mode of operation of a room terminal through a terminal keyboard or remote control. The system manager subsequently polls the terminal to determine if the room terminal is properly operating or if the wake-up alarm has been responded to. If not, hotel personnel may be dispatched to the room.

Title: Packet synchronization utilizing a multi-length packet format including check sequence (s)
IPC: H04L7/10
Filed: 1990-04-25
Abstract: PACKET SYNCHRONIZATION UTILIZING A    MULTI-LENGTH PACKET FORMAT INCLUDING CHECK SEQUENCE(S) Abstract Packet synchronization is obtained by employing a unique packet transport word including at least one prescribed parity check pattern in conjunction with a packet length indicator. An at least one prescribed parity check is computed over transport word length blocks of bits of an incoming packet and compared to an expected parity check pattern in predetermined bit positions in the incoming block of bits to identify possible transport word dandidates. Once a transport word candidate is identified, the packet length indicator is used to point to the next transport word candidate. Synchronization is declared upon obtaining a parity match for a subsequent transport word candidate pointed to by the packet length indicator. In a specific embodiment, at least two prescribed panty checks are employed to denote a possible transport word candidate. (FIG. 5).

Abstract: CONVEYOR BELT DUMPING MECHANISM USING HORIZONTAL IDLERS             OF VARYING LENGTHS         Inventor:         William A. Willson 83 Pheasant Drive Marietta, GA 30067 ABSTRACT   An  array of idlers supporting a conveyor  belt  except beneath   a  generally  crescent-shaped   section   opening outwardly to one side thereof. The array includes idlers of various  lengths  and orientations. Each of the  idlers  is disposed  perpendicularly  to the centerline of  the  belt.          Both   upstream  and  downstream  of  the   crescent-shaped section, pairs of idlers slope downwardly toward each other on  either side of the belt centerline. Where the  belt  is supported  by these pairs of idlers, it assumes  a  trough-like  configuration. Proximate the cresent-shaped  section, on  the  other hand, the idlers are unpaired and  disposed horizontally.  The  shortest of these  unpaired  idlers  is situated  to one side of the cresent-shaped section at  its greatest  transverse  width. On the other  side  but  still within  this  section,  the lip of the  belt is  virtually unsupported  forming a soft spot. This soft spot  is  sized and  situated  so that any burden carried by  the  conveyor tends  to  remain  on it unless  a  force  is  specifically applied  to  deflect objects within the  burden  laterally.     When  force  is applied which causes a  sufficiently  large object  to  move  transversely across the  soft  spot,  the crescent-shaped section acts as a chute. In such instances, the belt lip sags downwardly, becoming the  lowest part  of the  belt  and  allowing the deflected   objects  to  slide easily off the belt. As a result, less force is required to push objects off the side of the conveyor than would other-wise be the case, and the life of the belt is extended.

Title: Servo control method using a disturbance estimation observer
Inventor: TORII NOBUTOSHI
IPC: G05B13/04
Filed: 1990-01-17
Abstract: A B S T R A C T A servo control method capable of properly effecting disturbance estimation and removal by a disturbance estimation observer even in machines subject to substantial fluctuations in inertia, and improving the disturbance resistance of the machines.     An estimated disturbance (x) is obtained in accordance with an actual current command (I - y') and an actual motor speed (v) by a disturbance estimation observer (5), which includes four transmission elements (51 to 54) having transfer functions (Kt/Jm, K1, K2/S, 1/S) each depending on the torque constant (Kt), inertia (Jm), or parameters (K1, K2) corresponding thereto.  Gain adjustment and high-frequency component removal therefor are effected by a transmission element (3) and a filter (4), to determine a corrected estimated disturbance (y').  A servomotor is driven in accordance with an actual command current obtained by subtracting the corrected estimated disturbance (y') from a command current, thereby removing an influence of the disturbance.  The parameter (Jm) of the transmission elements (3, 51) is variably adjusted depending on changes of the inertia of the machine. attributable to changes of the operating state of the machine, so as to properly effect the disturbance estimation and removal even though the fluctuations of the inertia are substantial.

Title: Apparatus and method for separating zirconium isotopes using balanced ion electromigration
Inventor: JACKOVITZ JOHN F
IPC: B01D59/42
Filed: 1991-01-04
Abstract: W.E. 55,397 ABSTRACT OF THE DISCLOSURE      Both  a  method  and  apparatus  for  separating zirconium isotopes by balanced ion migration in a counterflowing electrolyte are disclosed herein.   In the method of  the  invention,  zirconium chloride  is dissolved in a solution of HCl, and a voltage of between  2  and  50  volts  is  applied  across  the electrolyte to create a flow of zirconium ions toward the cathode, and a counterflow of chlorine ions toward the anode which is balanced such that the lighter weight isotopes of zirconium migrate toward the cathode while the heavier weight zirconium isotopes stay in the vicinity of the anode.  The apparatus of the invention includes a polarizing assembly formed from a bundle of small diameter glass tubes aligned between the anode and the cathode.   The internal  shape of  the  tubes impedes kinetic  agitation movement of  the  zirconium ions in all directions except in the direction between the anode and the cathode,  thereby expediting the separation process.  Glass frits are used to partition off the electrolyte in the region of both the anode and the cathode so that the isotopes which eventually accumulate in these regions may be drawn off with a minimum of fluid agitation.

Inventor: CORCORAN GARY T
IPC: G06F15/16
Filed: 1991-02-21
Abstract: A processor specially adapted for use as a coprocessor. The processor is implemented as a microprocessor. The adaptations include the following: The microprocessor has a master-slave pin which receives an input which determines whether the microprocessor operates as a bus master or a bus slave. Certain output pins have three-state bus drivers which employ feedback to ensure that a signal on a line being driven by the driver has gone inactive before the driver is turned off. Instructions executed by the microprocessor permit specification of portions of the internal registers as sources and destinations and specification of the size of an ALU operation, permitting easy operation on data ranging from bytes through 24-bit pointers. Instructions are executed in an instruction pipeline and a separate I/O instruction pipeline. Some pipeline stalls are avoided by means of a special MOVE instruction which differs from an ordinary MOVE instruction in that it does not cause pipeline stall when it reads data from a register loaded by a preceding READ instruction. The microprocessor also has an Intel/Motorola pin whose input specifies the type of host processor the coprocessor is working with and further executes I/O instructions which permit the same code to be used with either host processor.
