Inventor: OOEDA YASUNORI
IPC: B21B37/00
Filed: 1979-01-31
Abstract: PURPOSE: To prevent previously the abnormal loop hanging on the material to be rolled, by, in controlling the tensile force between continuous rolling stands by FTC system, calculating a specific correcting value in order to correct compulsively the roll speed of the object stand when the tensile force, which is computed by an arithmetic unit, deviates from the upper and lower limits.  
     CONSTITUTION: When a material 18 to be rolled is delivered from a first stand and is bitten by a second stand, an arithmetic unit 22 calculates the tensile force t between the two stands from the rolling torque G 1  and rolling load P 1 , and feeds the tensile force to a substracting unit 25 and a comparator 23. To the comparator 23 are set previously upper and lower limit values. When the tensile force t deviates from the limit values, a gate 26 is opened and ordinary FTC control is discontinued. At that time, the tensile force deviation corresponding to a desired value tO and a tensile force-speed affecting coefficient α are inputted to an arithmetic memory unit 28 to calculate a speed correction ΔNt, hereby the roll speed of the first stand is corrected.

Filed: 1990-01-18
Abstract: PURPOSE:To detect minute leaking of a container by filling an enclosed container made of synthetic resin with high-temperature contents, or filling the container with contents and then heating the container, placing the container in enclosed atmosphere, and detecting the change in atmospheric pressure. CONSTITUTION:In a tightly closed container 1 made of synthetic resin that is an object to be inspected, a drum tube 3 and a bottom wall are formed of polypropylene resin, and a top wall 4 is formed of a laminate film. When a separating piece 8 made of polypropylene which is stuck to the peripheral part of the top wall 4 is pulled out, the top wall 4 is opened. The container 1 is filled with high temperature contents, or the container 1 is filled with contents and then heated. Then, the inside of the container becomes the pressure state higher than atmospheric pressure. The container 1 in the high pressure state is placed in a tightly sealed atmosphere 2. Then, the air in the container 1 leaks into the atmosphere 2 when leakage occurs because the pressure in the container 1 is higher than the atmospheric pressure, and the atmospheric pressure becomes high. The change in atmospheric pressure is detected with a pressure switch 6. Then whether the leaking occurs from the container 1 or not can be inspected.

Title: Method for electrolytic refining of copper
Inventor: ANDO KOJI
IPC: C25C1/12
Filed: 1998-01-21
Abstract: PROBLEM TO BE SOLVED: To grasp the effect of the org. additive in an electrolyte and to stabilize operation by executing energization using the surface of a cathode as an anode for a short time, executing ordinary energization after a specific pause time and measuring a cathode overvoltage. SOLUTION: Electrolytic refining of copper is executed by adding the org. additive, such as lacquer, in a slight amt. in an mg/l unit to the electrolyte, by which the smooth electrolytic copper having high purity is obtd. The electrolyte is withdrawn from the electrolytic cell under energization and the energization is executed by using an insoluble electrode consisting of platinum, etc., in the method for electrolytic refining of the copper. At this time, the energization using the surface of the cathode as the anode is executed for about 15 seconds with the electrolyte. As a result, the surface of the cathode is activated by decomposition of the electric double layers and deposits thereon. The ordinary energization is thereafter executed after the lapse of the pause time of 30 seconds to about 1 minute after the energization and the cathode overvoltage is measured.  The measurement is repeated with lapse of time with the withdrawn electrolyte and the denaturation amt. of the org. additive correlating therewith is evaluated from the change in the cathode overvoltage. The replenishing amt. thereof is then, determined.

Title: Multipurpose ball valve device
Inventor: KITAMURA KATSUAKI
IPC: F16K5/06
Filed: 1982-01-25
Abstract: PURPOSE:To make both the checking of backward flow during forward flowing and the drainage for freeze proofing possible by a structure wherein a reversible non-return mechanism is arranged inside the switching flow passage of a spherical valve body and the direction of said non-return valve is rendered to be freely changed-over from and to forward flow direction to and from reverse flow direction. CONSTITUTION:If the backward flow of the fluid such as waste water occurs due to the abrupt failure of water supply, the fluid applies its pressure to the lead valve 12 of the non-return valve 15 of the spherical valve body 8, resulting in pressing the lead valve 12 against a valve seat 10 so that a valve port 11 is tightly closed in order to check the backward flow of the fluid. On the other hand, in case that the drainage is intended to perform at a cold district, a lever 20 is displaced and the spherical valve body 8 linking through a handle shaft 18 with the lever 20 is turned 180 deg., resulting in stopping the reversible non-return mechanism A at the position facing toward an inlet 4 side. After the switching operation as mentioned above, the remaining water in the secondary pressure side opens the lead valve 12 of the non-return valve 15 to pass through the valve 15 and is discharged outside by opening water taps and the like while a main line stop valve being kept closed.

Title: Transplant/implant device and method for its production
Inventor: GROGAN SHAWN P
IPC: A61K35/32
Filed: 2000-11-13
Abstract: A transplant/implant device for delivering at least one predetermined biologically active compound to a human or animal host system or for another biological function in the host system is produced by genetically engineering vital chondrocytes or mixing chondrocytes with another type of native or genetically engineered cells or mixing chondrocytes with artificial particles having a size comparable to the size of cells or combining at least two of the named steps of engineering or mixing and by subjecting the chondrocytes or the mixture comprising the chondrocytes to three dimensional culture conditions for in vitro production of cartilaginous tissue whereby the cells and/or the artificial particles are immobilized in the cartilaginous tissue. The chondrocytes produce and maintain the cartilaginous tissue and the chondrocytes themselves or cells of another cell type immobilized in the cartilaginous tissue are able to produce and secrete the at least one predetermined compound. The artificial particles are e.g. biosensors. The chondrocytes as well as the cells of the other cell type may originate from the host or from a donor. The cartilaginous tissue proves to constitute favourable conditions for the vital cells and/or artificial particles immobilized therein and for the delivery of the predetermined compound also on a long term basis in particular by preventing or reducing unfavourable reactions by the host system such as immuno reactions or foreign-body reactions.

Title: Control of lighting installations
Inventor: PFEIFFER WALTER KARL
IPC: G01J1/42
Filed: 2000-11-16
Abstract: According to the invention, the proportion of sunlight (Is) and/or artificial light (IK) of the spectral power density (I lambda ) in a spatial volume, which is illuminated by sunlight (S) and artificial light (K), is determined using at least one sensor and/or filter located in the area concerned. The generated signals are saved and evaluated by an arithmetic unit. The wavelength-dependent ( lambda ) absorption of the sunlight (S), which traverses the entire earth's atmosphere, by gas molecules is measured in characteristic absorption bands (12, 14) using sensors which generate signals for the spectral power densities (I lambda ). The proportions of the sunlight (S) and the artificial light (K) are determined from the comparison of the spectral power densities (I lambda ). This method is used to control and/or regulate lighting installations in a room or in motor vehicles, in both cases even with varying amounts of sunlight (S). The method allows an adjustable spectral power density (I lambda ) or total illumination density of sunlight (S) and artificial light (K) to be maintained.

Abstract: PCT No. PCT/NO92/00007 Sec. 371 Date Nov. 3, 1993 Sec. 102(e) Date Nov. 3, 1993 PCT Filed Jan. 17, 1992 PCT Pub. No. WO92/12893 PCT Pub. Date Aug. 6, 1992.The invention relates to a method for loading and discharging tanks (1) for transporting oil, a method for transporting oil in tankers (1) and a pipe and valve system (6, 7, 8) in a tanker (1) for performing the method. According to the invention, gassing of hydrocarbon containing gas during loading and unloading is reduced by loading or unloading the cargo tanks (2) while the oil is maintained in contact with a generally saturated HC gas. This is done by saving the HC gas which is developed during loading or unloading, this gas later being used in further loading and unloading. This is made possible by a pipe and valve system (6, 7, 8) according to the invention. In accordance with one embodiment of the invention, the tanks are filled completely so that the oil is present in tank hatches (10) and risers (11) located at the top of the tanks (2). This results in that the gas volume above the cargo before a possible grounding is approximately equal to zero and, consequently, the necessary underpressure is obtained above the cargo for establishing a hydrostatic balance at the bottom of the tanker (1) with a minimum spill of a cargo.
