Title: Thermoplastic polymer composition
Inventor: ITOH ATSUSHI
IPC: C08L53/02
Filed: 1998-02-24
Granted: 2002-05-21
Abstract: The invention relates to a thermoplastic polymer composition comprising 100 parts by weight of a block copolymer and/or its hydrogenate having polymer blocks of an aromatic vinyl compound and polymer blocks of a conjugated diene compound, and from 5 to 95 parts by weight of a block copolymer having polymer blocks of an aromatic vinyl compound and/or an olefinic compound and polymer blocks having a constitutional unit derived from a (meth)acrylic compound; to a laminate comprising a layer of the composition and a layer of some other material; and to a hot-melt adhesive comprising the composition. As having good melt adhesiveness, the composition of the invention can firmly adhere in melt to various polar or non-polar materials. Using the composition, it is easy to produce laminates comprising a layer of the composition and a layer of some other material, through melt shaping or any other melt adhesion techniques. Since the composition of the invention is satisfactorily elastic and flexible, the laminates having a layer of the composition on their surface are flexible and elastic and have a good feel, and, in addition, they are highly safe because of their shock absorbability and cushionability.

Title: Sequential command repeater system for off-road vehicles
Inventor: WENDTE KEITH W
IPC: B60K25/00
Filed: 1998-06-11
Granted: 2002-04-30
Abstract: A control system for controlling outputs associated with off-road vehicles is disclosed herein.  The outputs are actuated by actuators in response to control signals generated by a control circuit.  In a normal mode, the control circuit generates the control signals based upon command signals generated by operator-actuatable command devices, and applies the control signals to the actuators to control the outputs.  In a record mode, the control circuit stores a sequence of commands in a memory circuit to record the sequential actuations of the command devices.  Then, in a playback mode, the control circuit generates the control signals based upon the recorded command sequence instead of the command signals. Playback can be triggered manually by a playback switch, or automatically based upon the geo-graphic position of the off-road vehicle.  The control system can record and playback more than one command sequence.  Each sequence step generates a recorded command which can depend upon a recorded event based upon values of a timer, geographic position or feedback signal.  In addition, the operator can erase, view and edit the commanded sequences.  The operator can also download and upload command sequences.

Abstract: A secure metering vault for use with a host printing module via a secure communication link includes a secure output device such as a light emitting diode (LED) configured for outputting the available postal funds stored in the secure metering module in response to a detected malfunction in the secure communication link. The vault includes a processor that monitors the condition of the secure communication link, and that controls the storage and updating of the stored available postal funds in a nonvolatile memory. If a failure is detected in the communication link, the processor outputs to the LED the stored value of the available postal funds based upon a prescribed format, such as Morse code or some other blinking pattern that is equivalent to the postal funds remaining in the vault. Use of the secure output device to output the stored available postal funds enables a user to recover the funds without tampering with the secure metering module, which may otherwise cause self-destruction of the vault or deletion of the available postal funds from memory.

Granted: 2004-11-09
Abstract: In a method and a device for coding binary matrices, in particular sparse binary matrices, a matrix is gradually partitioned into sub-matrices. During the gradual partitioning the number of binary ones are counted for each resulting sub-matrix. If a resulting does not consist of mixed symbols no further partitioning of that sub-matrix is required. The counted number of binary ones for each sub- matrix is then coded and transmitted. The method provides an efficient coding particularly for sparse binary matrices such as bi-level images or bit maps.

Title: Process for purifying a gas by adsorption
Inventor: MONEREAU CHRISTIAN
IPC: B01D53/053
Filed: 2000-01-07
Granted: 2008-03-25
Abstract: A variable fraction of the residual gas is recycled (between 0 and 30% of the purified gas flow produced) in the impure gas to be treated, with the rest of the residual gas forming a purge, and the duration of the cycle T is reduced when recycling is done, with greater reduction when the recycled fraction is higher  Process for purifying a gas containing impurities which can be preferentially adsorbed, in particular hydrogen, by pressure swing adsorption (PSA) using several adsorbers (1, 2, 3) with each adsorber passing through successive operating phases, out of phase with the other adsorbers by an nth of the cycle duration T, where n is the number of adsorbers. The operating phases are: isobar adsorption at a high pressure of the cycle, with the impure gas being admitted at one end of the adsorber, circulating through it and extraction of the purified gas from the other end; regeneration of the adsorber finishing with at least one stage of extracting a residual gas from the adsorber in back-flow, and raising the pressure back to the high pressure of the cycle. The fraction of gas recycled is temporarily zero and temporarily between 10 and 30% of the purified gas. Gas is recycled when and only when the gas flow produced is greater than a set value. The flow of impure feed gas is kept constant and the amount of recycled gas is varied as a function of the purified gas produced, with the variations in the two gas flows being in the same direction. The reduction in cycle time is between 1 and 30% of the cycle with no recycling. The regeneration starts with a depressurisation stage in back-flow by balancing the pressure with another adsorber which is being repressurised. The regeneration is finished with two final stages: a depressurisation in forward flow to a low pressure and a purge in back-flow. The depressurisation stage by balancing is followed by a second depressurisation stage in forward flow, using the gas from the adsorber during this stage as purge gas. The adsorption unit has three adsorbers and the gas from the adsorber during the second depressurisation stage is sent to an auxiliary purge gas storage, or the adsorption unit has four adsorbers and the gas during the second depressurisation is sent directly to purge in forward flow another adsorber.
