Title: Giant jem wing skimmer and seperator for oil and other floating materials, liquids
Inventor: MEIER DETLEF G
IPC: B63B35/32
Filed: 1990-05-14
Abstract: ABSTRACT             OIL SPILLS ARE VERY SERIOUS AND ARE A CONSTANT DANGER TO OUR ENVIRONMENT.CLEAN UP EFFORTS ARE COSTLY,TIME CONSUMING AND ACCOMPLISH LITTLE. WITH THE SKIMMERS AND SEPERATION PROCESS LARGE VOLUMES OF WATER AND OIL CAN BE SEPARATED,ELIMINATING THE PURPOSE OF EXISTING SKIMMERS WHICH ARE MOSTLY DESIGNED TO SKIM OIL ONLY. AND AT THAT IN VERY LITTLE QUANTITYS.THE ALASKAN OIL SPILL PROVES, THAT A BETTER SYSTEM AND PROCESS IS NEEDED. THEREFORE I DESIGNED THE SKIMMER AND SEPERATION PROCESS WHICH I HOPE TO PATENT. THE BENEFIT OF THE SKIMMER AND SEPERATION OR SEPERATOR PROCESS IS, THAT IT           FIRST:  GET TO THE AREA OF THE SPILL FAST. SECOND: ISOLATE THE LEAK AROUND THE HULL WITH SKIMMERS AS EXPLAINED   THIRD:  USE THE WINGSKIMMER TO SKIM THE OIL THAT ESCAPED. THE SHIP CAN AFFORD DIFFERENT SPEEDS BECAUSE IT DOES NOT SKIM OIL ALONE,BUT TAKES OIL AND WATER FOR PROCESSING.TO EQUALIZE THE BUILD UP OF WATER IN FRONT OF THE SKIMMER (DRAG),A WATER THRU FLOW IS CREATED TO MINIMIZE THIS PROBLEM.           FURTHER MORE,THE SKIMMER AND SEPERATOR CAN BE USED IN HARBOR SURFACE CLEAN UP,RIVERS AND LAKES. AS FOR THE SEPERATION PROCESS ON BOARD TANKERS. EVERY TANKER CAN AFFORD TO HAVE ONE ON BOARD FOR TANK CLEANING, SAVING THE OIL THAT OTHERWISE WOULD BE DISCHARGED INTO THE OCEANS OR WATERS.

Title: Pneumatically powered valve actuator
Inventor: ERICKSON FREDERICK L
IPC: F01L9/20
Filed: 1990-12-24
Abstract: ABSTRACT: Improved pneumatically powered valve actuator.     An electronically controllable pneumatically powered valve actuating mechanism for use in an internal combustion engine is disclosed. The engine is of the type having engine intake and exhaust valves with elongated valve stems. The actuator has a power piston reciprocable along an axis and adapted to be coupled to an engine valve and a pneumatic arrangement for moving the piston, thereby causing an engine valve to move in the direction of stem elongation between valve-open and valve-closed positions. The pneumatic arrangement includes a pair of control valves which are movable relative to the piston for selectively supplying high pressure air to the piston. Each control valve includes a thin walled portion having an inner cylindrical surface which slidingly egnaging a portion of one of the enlarged diameter cylindrical portions of the piston. The inner cylindrical surface includes an end portion of enhanced strength and reduced inner diameter which is too saml to receive the enlarged diameter cylindrical portion of the piston. The piston includes enlarged diameter cylindrical portions which cooperate with the motion of the corresponding control valve to stop the supply of high pressure air to the piston. A pneumatic damping arrangement imparts a first decelerating force to the piston when the engine valve reaches a first separation from one of said valve-open and valve-closed positions to begin reducing engine valve velocity as the engine valve approaches said one position, and imparts a second lesser decelerating force to the piston when the engine valve reaches a second lesser separation from that one position. A resilient member cooperates with and is deformed by the air control valve to prevent the application of piston moving air pressure to the piston when the air control valve is in the closed position, and included is an arrangement for adjustably selecting the amount of deformation of the resilient member when the air valve is in the closed position. An initializer to force the piston to one of its extreme positions upon start up, a pressure regulator, and an arrangement for minimizing surface tension induced valve sticking problems are also disclosed.

Title: Container for bulk goods, fluids and the like
Inventor: BOOTS GERARDUS A M
IPC: B65D77/06
Filed: 1991-03-04
Abstract: This invention relates to a container for bulk goods, fluids and the like, comprising an outer envelope, which can be closed at both ends, and an inner member, which is connected to the outer envelope at at least four points spaced about the circumference of the outer envelope and has a length that is 30-100% of the height of the container to be formed.        According to the invention, for obtaining a substantially block-shaped container with a bottom and cross-sections parallel thereto, substantially in the form of a rectangle deviating from a square, the starting-paint is a rectangle with the desired outer dimensions and at least one inscribed circle which touches both long sides but not at least one short side of the rectangle. A first line extends parallel to the long side and through the centre of the inscribed circle and a second line extends parallel to a short side and through the centre of the inscribed circle. These lines divide the rectangle into subrectangles each having an angular point coinciding with one of the angular points of the rectangle. A bisector is drawn in the rectangle from each coinciding angular point. Located in each bisector is the centre of a further circle which touches the long and the short side that meet at the angular point from which the corresponding bisector has been drawn. The intersections of said further circles and said inscribed circle define the points where the outer envelope is connected to the inner member. These intersections do not lie outside the subrectangle with the bisector in which lies the centre of the corresponding further circle. The length of the outer circumference of the outer envelope is defined by the sum of the four lengths of the arc of the four further circles between the points where the further circles intersect the inscribed circle and the sum of the lengths of such portions of the outer circumference of the inner member as are not covered by the further circles.

Inventor: BAILEY ROBERT W
IPC: A61B17/02
Filed: 1991-03-28
Abstract: A device which can be used in a laparoscopic surgical procedure is disclosed.  The device is to be used in the surgical procedure as a retractor i.e. to displace and hold internal organs of a patient away from the organ which is the surgical objective.  The device, which is essentially a long thin narrow tube, is partially inserted into the abdomen of a patient through a tiny incision in the abdomen wall.  Retractor action is accomplished by the movement of levers, slides or buttons located on the end of the tube that remains outside of the patient.  These levers, slides or buttons control the opening or closing of components, such as finger-like protuberances, that depend from the end of the tube that is within the patient.  These protuberances push and hold floppy organs away from the surgical objective so that the surgical team can clearly view the organ using the laparoscope and remove the organ with tiny laparoscopic instruments.  In this manner radical incisions, recovery time, and scarring are greatly reduced.
Patent CA-2040305-A1 (CA)
Inventor: KAIDA YOSHIMASA
IPC: G02F1/1343
Filed: 1991-04-12
Abstract: Material obtained by reducing indium-tin-oxide is used as a shading material, for example, between picture elements of a liquid crystal display.   As  ITO is reduced,  its light transmission diminishes to a low enough level for the product to be used as a shading material.   ITO is widely utilized as a transparent electrode material in a liquid crystal display.  Because the region adjacent to the  transparent  electrodes  each  of  which  composes  a picture element electrode is generally where the shading is needed, the necessary shading member may be formed by reducing the region of ITO which is not protected with a mask, while protecting the ITO region which is to be used as  the  transparent  electrode.   Because  this  shading member is to exist in a single layer film of ITO,  no difference in level occurs between the shading member and the transparent electrode.  In addition, there is no need to separately form a film for forming the shading member, enabling the number of manufacturing steps to be reduced.
