Title: Method for the preparation of an acidic dicarboxylic acid ester of cellulose ether
Inventor: CHIBA TOHRU
IPC: A61K47/38
Filed: 1986-09-17
Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE       A hydroxypropoxyl-containing cellulose ether, e.g. hydroxypropyl cellulose and hydroxypropyl methyl cellulose, is esterified into an acidic dicarboxylic acid ester useful as a enteric coating material of solid medica-ment forms. The esterification reaction of 100 parts by weight of the cellulose ether with phthalic or succinic anhydride optionally combined with acetic anhydride is performed in 200 to 700 parts by weight of acetic acid as a solventin the presence of 50 to 150 parts by weight of an alkali metal acetate, e.g. sodium acetate. The cellulose ether product is so tough and resistant against attack of a simulated gastric juice that the solid medicament forms coated therewith are imparted with highly reliable enterosolubility.

Title: Method of controlling product tension in a rolling mill
Inventor: MAROTI ENDRE S
IPC: B21B45/02
Filed: 1986-10-06
Granted: 1991-01-29
Abstract: ABSTRACT OF THE DISCLOSURE         In a rolling mill wherein product is rolled continuously in successive first and second blocks at the finishing end of the mill, a pinch roll unit is interposed between the two blocks.  The motor speed of the pinch roll unit is employed in combination with other variables to preset the motor speed of the second block prior to entry of the product front end therein.  The preset motor speed of the second block produces an acceptable level of interblock product tension once the product has entered the second block.  Thereafter, product elongation in the first block is monitored and required adjustments to the motor speed of the second block are made in order to maintain interblock product tension within acceptable limits.

Title: Work saving system for preventing loss in a computer due to power interruption
Inventor: BYRD KERRY
IPC: G06F11/14
Filed: 1987-08-07
Granted: 1991-03-26
Abstract: ABSTRACT OF THE DISCLOSURE     A device for preventing unintentional loss of data in a computer system as a result of electrical power interruption comprises an uninterruptible power supply, a monitor circuit for generating signals when the main power is interrupted and restored and for monitoring the condition of the uninterruptible supply, and an auxiliary memory circuit which is connected to the computer's data and address bus.  The memory circuit includes a large non-volatile memory and a program stored in ROM which takes over control of the computer and is executed by the CPU when a power interruption is signalled by the monitor circuit.  The program allows any operation already in progress to be completed and then directs a transfer of the computer's operating state and any application programs and operating system from the computer's RAM to the memory circuit's nonvolatile memory.  When main power is restored, the ROM program directs the CPU to reload the application programs and operating system into the computer's RAM and to reset the state of the CPU.

Title: Demodulator including sweep controller for controlling synchronization capture range
Inventor: YOSHIHARA MASASHI
IPC: H03D3/02
Filed: 1988-05-18
Granted: 1991-01-08
Abstract: Abstract The invention relates to a multi-phase PSK demodulator.          It includes a quadrature detector for demodulating a PSK signal in response to a carrier wave to provide demodulated analog signals.          A converter is provided for converting the demodulated analog signals to digital signals.  A synchronization decision circuit responsive to the digital signals decides whether or not synchroni-zation is established and provides a first control signal.  A carrier recovery circuit, including a voltage controlled oscillator provides an error voltage in response to the digital signals.  The voltage controlled oscillator provides the carrier wave in response to the error voltage.  A false synchronization detector detects a false synchronization by monitoring the error voltage, thereby providing a second control signal. Finally, a sweep controller is provided for supplying a sweep signal or a predetermined level signal to the input of the voltage controlled oscillator in res-ponse to the first and second control signals.  The invention is capable of cancelling false synchronization when it occurs.

Title: Tray carton end flap auxiliary sealer
Inventor: CONFORTO PETER M
IPC: B65B/

Granted: 1991-11-26
Abstract: Abstract of the Disclosure In a machine for packaging articles  in a tray carton a first stationary rail section folds up the end panels of a moving tray  carton  blank  to  an  intermediate  position  and,  after  the application of glue to either the end flaps or the and panels, a third stationary rail section completes the operation of folding the end panels of the moving blank up against the end flaps. A second normally  stationary  section  located  between the  first  and  third sections maintains the end panels in their intermediate positions. When the machine stops for any reason the second section moves the end panels of the tray carton located at that station into contact with the end flaps to adhere the end panels to the end flaps of the stationary tray carton.

Title: Heat echanger defrost control
Inventor: CHABROS JOSEPH M
IPC: F24F12/00
Filed: 1988-08-11
Granted: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE          An air-to-air heat exchanger in a ventilating system of a building commonly includes a core with mutually exclusive portions in thermal contact that define separate air flow paths between respective pairs of inlets and outlets.   Sensible heat from humid,  exhausted air is conducted to incoming cold supply air in order to conserve heat energy and on cold days with temperatures well below freezing, condensate formed in the exhaust air passages of the core may freeze and disable the exchanger.  This problem is overcome by combining warm exhaust air from the building with the cold supply air, but thorough mixing is required since the incoming air is stratified and resists complete mixing.  A hollow cylindrical damper having an arcuate wall with an aperture and an open rear wall is rotatably positioned in communicable relation between an inlet pair for the cold supply air and warm exhaust air and a mixing chamber within the exchanger.   A temperature responsive device rotates the damper to contollably combine predetermined streams of warm and cold stratified air, admitted through the aperture, that are mixed effectively within the damper by a novel baffle arrangement and expelled into the mixing chamber through the open rear wall.

Title: Method for computing transitive closure

IPC: G06F17/30
Filed: 1988-08-18
Granted: 1991-11-26
Abstract: A METHOD FOR COMPUTING TRANSITIVE CLOSURE          Abstract A method and apparatus for creating a transitive closure of a database when the database is stored on a secondary storage in the form of links connecting nodes. The method consists of partitioning the database, transferring one partition at a time from the secondary storage to the main memory, and processing a partition in such a way that accesses to the portions of the database not in main memory are minimized. As much of the unprocessed database as would fit a predetermined fraction of main memory is fetched as one partition, and if, during the processing of this partition, the main memory becomes full, the size of the partition is reduced dynamically by discarding a portion of the database in the current partition, and including this portion in the next partition. The processing of a partition involves, for each node in the partition, the operation of creating a direct connection between every pair of nodes that are indirectly connected through this node.

Title: Titanium(iv)-chelates and the use thereof in printing ink
Inventor: BARFURTH DIETER
IPC: C07F5/00
Filed: 1988-10-04
Granted: 1993-07-06
Abstract: ABSTRACT OF THE DISCLOSURE:          The present invention relates to new alkoxy-titanium(IV)-chelates and to the use thereof in printing inks based upon nitrocellulose or other cellulose-ester derivatives.   The new chelates are characterized in that they contain citric-acid alkyl-esters as chelate-formers.  Like other titanium-chelates, they delay the known catalytic action of titanium components during cross-linking reactions.  When used in printing inks, the new titanium-chelates, and alcoholic solutions thereof, have the advantage of possessing only a small amount of inherent colour,  so that they scarcely discolour the printing inks.  Another advantage of the new chelates is that they also do not interact with antioxidants based upon phenol and they may therefore be used for printing inks applied to a polymer background with such antioxidants, with no fear of discolouration.
