Title: Using butenes to fractionate methanol from methyl- tertiary-butyl ether
Inventor: HUTSON THOMAS JR
IPC: C07C41/00
Filed: 1982-06-01
Granted: 1984-08-07
Abstract: Abstract of the Disclosure Butenes are added to the methanol-containing methyl-tertiary-butyl ether (MTBE) reactor effluent fractionation to effect recovery of substantially methanol-free MTBE bottoms product. Methanol analysis taken below the fractionator feed locus manipulates control of butenes addition. In an embodiment, the methanol-butenes-containing overhead stream from the fractionation is treated over activated alumina to adsorb methanol, yielding a methanol-free butanes feed for HF alkylation of isobutane. The used adsorbent can be regenerated using hot butenes product and/or MTBE reactor feed vapor with the recovered methanol being recycled to the MTBE reaction.

Abstract: ABSTRACT OF THE DISCLOSURE            A handle or the like of a briefcase is marked with a three-dimensional marking preferably on one side of the grip portion, as a directional orientation as to where the lid of the case is disposed, to prevent undesired opening of the case when it is positioned upside down.  The device simplifies the task of directional orientation and is much less expensive than the known mechanisms preventing the manipulation of the locks with the case upside down.  The advantage over directional orientation by stickers or the like indicating the top or bottom of the case is in that the present invention, while retaining an extremely low cost of the feature, enables its function in the dark.  Also, it enables the recognition of the correct position of the case by a blind person or the like.

Title: Control circuitry for water level control of pools
Inventor: LIVELY OLIN A
IPC: G05D9/12

Granted: 1984-07-10
Abstract: O. A. LIVELY CONTROL CIRCUITRY FOR WATER LEVEL CONTROL OF POOLS Abstract of the Disclosure Circuitry for automatically controlling the water level of swimming pools with a multi-level detecting sensor for directly sensing the pool water. A low voltage oscillator in the input portion of the circuitry detects the presence of water above or below each level sensing electrical contact of the sensor by a change in oscillator amplitude in response to impedance from the contact to ground. Signal threshold circuitry changes in output signal in response to the amplitude of the oscillator signal. Delay circuitry integrates the output of the threshold signal to avoid responding to spurious changes in water level, such as wave action in the pool. Monitor circuitry disposed between the delay circuitry and the water fill, water dump, and pump control circuitry monitors signals received from the sensor or generated by the input circuitry to detect any malfunctions in the sensor or the control circuitry, such as improper sequence of the water level signals, to disable further filling of the pool. Bi-stable switch circuitry controls filling of the pool and is responsive to differing pool levels to cause filling of the pool to commence or to stop.

Abstract: ABSTRACT            IMPROVEMENTS IN OR RELATING TO DIGITAL TRANSMISSION                  SYSTEMS     An aligner with a time switching capability is disclosed.  The aligner has a store for storing incoming data.  The store is sufficiently large that it can hold more than one frame of information.  Data is written into the store under the control of clock signals associated with the incoming data.  Data is read from the store under the control of a local clock.          Read addresses are generated by a unit which is so arranged that if a clash between the current write address and the generated read address is sensed to be imminent, reading of the corresponding address in the previous or subsequent frame occurs.  Thus, the aligner can operate as a time switch and clashes between reading and writing are avoided by allowing slippage of one frame.

Title: Method and apparatus for encoding and decoding  digital information
Inventor: TANAKA MASATO
IPC: G11B5/09
Filed: 1983-08-31

Abstract: ABSTRACT OF THE DISCLOSURE Digital data formed of binary bits of first and second values occupying consecutive bit cells of predeter-mined intervals are encoded such that successive binary bits of the first ox second values are represented by predetermined separations between succeeding transitions.          A first transition is produced at a first reference point in a bit cell when a binary bit of the second value changes over to a binary bit of the first value.  When successive binary bits of the first value are sensed, a respective second transition is produced at a second reference point in a bit cell after sensing every 2 or 3 binary bits of the first value.  When successive binary bits of the second value are sensed, a respective second transition is produced at the second reference point in a bit cell when at least two successive binary bits of the first value are followed by a binary bit of the second value and also after sensing every 3 or 4 successive binary bits of the second value, such that the last-mentioned second transition at the second reference point is separated from the closest first transition thereto by at least 1.5 bit cell intervals but no more than 4.5 bit cell intervals and successive ones of the second transi-tions are separated from each other by no more than 4 bit cell intervals.

The flame retardancy is achieved by the addition of organophosphorus or halogenated organophosphorus flame retardants.  High impact resistance is achieved by the incorporation of a rubbery polymer into the polymeric composition.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention discloses F(ab')2 or Fab fragments of antibodies to:  a)  human chorionic gonadotropin (hCG), hCG alpha subunit, hCG beta subunit, or an hCG-like material; or b)  other tumor specific or tumor associated molecules, to include carcinoembryonic antigen (CEA), alpha fetoprotein (AFP), human melanoma associated antigens, human sarcoma associated antigens or other antigens, which are radiolaheled with technetium-99m (Tc-99m).  When the F(ab')2 or Fab fragments of antibody to such tumor associated antigens are injected intra-venously into a patient, the radiolabeled composition accumulates at tumor sites.  The accumulation of the cancer seeking radiopharmaceutical at tumor sites permits detection by external gamma scintigraphy.  Thus, the composition is useful in the monitoring, localization and detection of cancer in the body.

Abstract: ABSTRACT OF THE DISCLOSURE           A copier-printer is employed in conjunction with an optical scanner and associated character recognition logic to transmit information contained in a document over a telephone line or other communcation line.  The copier-printer is used to make a copy of the document which is stored in the duplex tray.  When a buffer memory associated with the communication line is ready to receive further information for transmission, the copy is retrieved from the duplex tray and circulated through the copier-printer to the optical scanner.  The scanner provides the information from the copy to the buffer memory in a non-coded format except to the extent that the character recognition logic is able to code some or all of the information.  The copy is ad-vanced from the scanner to a mailbox in the form of a limited access compartment at the bottom of the collator for the copier-printer.  The copier-printer may be used to receive information transmitted over the communication line by temporarily storing the information in the buffer memory and then printing the information on paper which is routed to and stored in the mailbox.  Information provided to the print buffer for printing can be checked for printing accuracy by scanning the resulting printed paper using the optical scanner and comparing the scanned information with the information originally entered in the print buffer.
