Inventor: OKADA OSAMU
IPC: H01M8/06
Filed: 1990-05-15
Abstract: In a fuel cell power generation system for use with a fuel gas which is prepared by desulfurizing a raw fuel material such as naphtha, LPG, town gas, or the like and then, processing it by steam reforming reaction and thus, consists mainly of hydrogen or a process of producing the fuel gas, the desulfurization of the raw fuel material is implemented using a copper/zinc desulfurizing agent. As a result of the desulfurization, the raw fuel material is desulfurized at a higher level and the deterioration of a steam reforming catalyst employed is prevented. Accordingly, steady long-run operation of the fuel cell will be ensured. Also, upon the steam reforming reaction, the S/C (the mole number of steam per one mole of carbon in a raw fuel material) is reduced and thus, the concentration of hydrogen in the fuel gas will. be increased providing an improvement in the efficiency of power generation.

Abstract: METHOD AND APPARATUS FOR VERIFYING MICROCIRCUIT FABRICATION                        PROCEDURE     ABSTRACT OF THE DISCLOSURE     An apparatus is used to perform a fabrication proce-dure on a microcircuit under control of specification data. The procedure may include making relatively undetectable modifications to the microcircuit using a focussed ion beam to  deter  unauthorized  reproduction  and/or  use  of  the microcircuit.   The output of the apparatus is tapped to generate record data of the signals actually applied to control the focussed ion beam to perform the procedure. The record data is written into at least one verification data storage area of the microcircuit, preferably using the focussed ion beam.  During testing of the microcircuit, the data written into the storage area is read out and compared with the specification data and generated record data. Proper performance of the procedure is verified if the compared data correspond to each other.

Patent CA-2037861-A1 (CA)
Inventor: SCHRODI KARL
IPC: H04L12/54
Filed: 1991-03-08
Abstract: State of the art/technical problem: When a connection is set up by a switching network 20, the path is selected according to the instantaneous switching network utilisation and is maintained during the connection. The problem of eliminating local blockages through rearrangement of existing connections is not adequately solved due to interferences which thereby occur. Fundamental concept: To provide for ATM with virtual connections the same devices as those which guarantee the correct sequence in connectionless operation. Solution: An output unit 30 is connected downstream of each output of the switching network which guarantees the correct sequence. Advantage: Virtual connections can be adapted at any time without interference to the instantaneous switching network utilisation. The guarantee of the correct sequence can be implemented in such a way that delay jitter is also largely eliminated. <IMAGE>

Title: Variable top curb mold
Inventor: CERQUOZZI LUIGI
IPC: E01C19/00
Filed: 1991-06-03
Abstract: ABSTRACT OF THE DISCLOSURE         A Method and apparatus for continuously forming concrete curbs is disclosed, in which the elevation of the top surface of the curb may be varied independently of the lower portion of the curb.  A curb mold according to the invention employs a top plate to shape the top surface of the curb being formed within the mould.   Positioning means,  such as a hydraulic cylinder, mounted on the curb mold, may be used to controllably adjust the vertical position of the top plate relative to the curb mold so as to adjust the height of the finished curb.  The design of the top plate ensures that an acceptable surface finish is obtained,  regardless of the position of the top plate, so that manual refinishing of the curb, after the curb has been formed in the mold,  is not required.

Title: Single-use disposable molten metal inclusion sensor
Inventor: NAKAJIMA HIDEMASA
IPC: G01N33/20
Filed: 1990-04-27
Abstract: A molten metal inclusion sensor (40) comprises a single use disposable probe (41) which is detachably connected to a support member (42). The probe (41) may comprise a tube (44) of heat resistant material having an inner electrode (48) mounted on its interior wall and an outer electrode (50) mounted on its exterior wall, the molten metal entering the tube interior through an orifice (45) in its wall past a jet-preventer insert (49) upon its immersion in the molten metal, whereupon the flow of metal with entrained inclusions is monitored by measuring the voltage between the electrodes (48, 50). Alternatively the tube (44) may be of electrically-conductive heat-resistant material and constitute the inner electrode (48). The flow may be assisted by a reduced pressure established within the tube, or may be slowed by a positive pressure to maintain the Reynolds number of the flow below 2000. The tube interior is divided by a narrow bore (52) into two compartments (40a, 40b) so that metal enters one compartment (40a) and freezes in the bore (52) so that it cannot enter the second compartment (40b), protecting the vacumm source if provided and establishing the quantity of metal entering the probe. The orifice (45) is closed by a meltable cover (46) and the cover is protected by a meltable shield (47) to enable the probe to be passed through an overlying slag layer without entry of slag to the probe interior. Various suitable materials are disclosed for the electrodes and for the body of the probe which should have a useful life in the bath of about 2 minutes.

IPC: B65G39/071
Filed: 1992-04-15
Abstract: 13                    TH2-020.P01 Abstract Wide Belt Alignment System The present invention relates to a conveyor belt alignment system by which a pair of alignment rollers are mounted on a carrier frame about a pivot axis that is situated at the approximate transverse center between opposed longitudinal side edges of a conveyor belt. The alignment rollers are spaced longitudinally to accept and form a portion of the conveyor belt into a substantial "s" configuration. The centrally pivoted carrier frame and alignmentrollers are pivoted by a pair of bladders 50, 51. Inflation of the bladders is controlled through a sensor 54 provided to detect the transverse position of an adjacent belt edge. If the belt edge shifts in one direction, the sensor detectssuch motion and operates the drive to selectively inflate one or the other of the air bladders to correspondingly shift the belt aligning rollers. The misaligned belt is brought back to the desired tracking configuration where the sensor detects the desired orientation and permits the system to return to a normal, desired operating mode.

Inventor: FOSTER DONALD C
IPC: C07K19/00
Filed: 1990-12-28
Abstract: Human protein C molecules are modified to provide increased resistance to inactivation by human plasma factors while retaining substantially the biological activity of human protein C. The modifications are generally to the heavy chain of protein C, which chain may be substituted with a protein C heavy chain of non-human origin, such as bovine, yielding a chimeric protein C molecule. The human protein C heavy chain may also be modified to be human-like, in that at least one amino acid from a non-human sequence may be substituted for the corresponding residue(s) of the human sequence, thereby allowing the molecule to retain substantially human characteristics yet having increased resistance to inactivation. Also included are methods for producing the modified protein C molecules and pharmaceutical compositions thereof. The modified molecules, having an increased half-life in human plasma, are particularly useful for treating coagulation-related disorders, such as protein C deficiency or thrombosis, or for promoting fibrinolysis in a patient.
