Abstract: A tool is intended for use in an oil or gas well to retrieve a drilling or production string from the well, particularly in a situation where the casing or formation has collapsed, thus gripping the drilling or production string. The tool has a driven member (63) which presents, at its lower end, a self-tapping thread (65) such as a counterclockwise self-tapping thread. The tool includes a ratcheting arrangement (48, 56) which can drive the driven member (63) in a counter-clockwise direction when the tool is lowered relative to the driven member. The tool can be repeatedly raised and lowered thus enabling the selftapping thread to be engaged with the top of the drilling or production string.

Title: Apparatus and method of short circuiting arc welding
Inventor: PARKS JOHN M
IPC: B23K9/073
Filed: 1989-11-14
Granted: 1994-09-06
Abstract: Apparatus and method to reduce spatter and allow better semi-automatic welding in short circuiting arc welding of the type using a single D.C.  power supply for causing a welding current to pass through a welding wire extending variable distances  from a holder and between the welding wire and a workpiece at a molten metal pool on the work-piece.   The welding current flows  in response to an arc voltage while the welding wire is fed from the holder toward the workpiece whereby the welding wire is subjected to a succession of welding cycles each of which include an arcing condition during which the wire is spaced from the pool and a short circuit condition during which a molten metal ball formed on the end of the wire contacts the metal pool and then transfers from the wire to the workpiece by a necking action.  In this type of welding operation, the invention involves the application of a preselected amount of energy into the wire during the arcing condition for each welding cycle, which preselected amount of energy slightly exceeds the known value of energy necessary to melt  a given volume of metal to form a consistent molten metal ball onto the end of the wire. This constant energy is divided between the resistance heating of the wire extending from the wire hold-er and the anode heating caused by the arc during each arc-ing condition of a cycle.  Consequently, constant energy is inputted to the end of the wire irrespective of changes in the amount of wire extension or stick-out.

Title: Container for holding equipment during sterilization
Inventor: SCHNEIDER EDWARD T
IPC: A61L2/16
Filed: 1990-03-22
Granted: 1995-11-07
Abstract: A liquid sterilizing system (A) defines a basin (10) in which a container (B)  is removably disposed.   The liquid sterilizing system selectively pumps sterile rinse liquids from a supply (24)  and liquid sterilant solutions from a supply  (70)  into  the  basin  filling  the  basin  and  the container.  The container includes a lower shell having a bottom wall (34) that defines an aperture (32) for receiving sterilant and sterile rinse liquids.  A nozzle plate (44) is mounted close to but spaced from the shell bottom wall to define a tortuous liquid distribution path (40) between the inlet aperture and nozzle plate apertures (90).  A barrier (96) divides the liquid receiving portion and a drain portion of the liquid distribution path between the shell bottom surface and the nozzle plate.  A cover (80) has a downward depending peripheral wall (82) which is offset from the shell peripheral wall (86) by the spacers (88) to define a tortuous vent path (48) therethrough.  The container is lifted out by handles  (100)  which enable the container to be removed without disturbing the transparent cover,  hence,  without disturbing the sterile condition of the items within the container.   In this manner,  the sterilized items can be inventoried and maintained sterilized in the container for an extended duration.

Abstract: CONNECTOR FOR LATERAL CABLE OF TIRE CHAINS                         ABSTRACT         Traction-enhancing tire chains with a lateral cable having a tension-applying connector for inter-connecting the opposite ends of the lateral cable for attaching the tire chains to a tire.  A clasp is attached to a pin slidably disposed in a cam slot defined in a tensioning lever attached to one end of the lateral cable.  The clasp hooks about a selected anchor on the opposite end portion of the lateral cable and applies tension to the lateral cable as the lever is rotated to a tensioning position.  The clasp slides along the cam slot and is pivotable with respect to the lever.  A hook on the movable end of the lever extends over the lateral cable to hold the lever in the ten-sioning position.  The lever and a hook which is also slidably disposed in the cam slot cooperatively hold excess cable against the side wall of the tire to keep it from flapping about during use of chains incorporating the fastener.

Title: Device for separating hydrocarbon products from water
Inventor: NOESTHEDEN ANDREW
IPC: B01D17/02
Filed: 1991-12-17
Granted: 2002-11-12
Abstract: A device is disclosed for separating hydrocarbon products or oil from water. The device includes a receiving tank defining a reservoir which receives a mixture of water and oil. The oil floats above the water and thus forms an upper layer in the receiving tank. A skimmer skims the upper layer from the receiving tank and channels the skimmed portion to a pumping chamber. A venturi pump then pumps the skimmed portion from the pumping chamber to a settling tank which then separates the oil and water. The skimmer includes floats which vary the depth of the skimmer as a function of the liquid level in the receiving tank.

Granted: 2004-06-08
Abstract: Fertilizer/pesticide compositions are disclosed which include a fertilizer component and an active component. The fertilizer component includes plant nutrients, and the active component includes an active material, such as a pesticide, which has a desired effect on plant growth or health when released to the plant over an extended period of time. In a preferred form, the fertilizer;component is admixed with the active component and a binder end compressed to form a briquette in which the fertilizer component occludes the active component. The briquette is essentially free of significant quantities of materials which have a high solubility in water. Thus, when a briquette is placed in the soil, it releases nutrients and the active material into the soil over an extended period of time for delivery to the plant. A method of treating plants with such fertilizer/pesticide compositions is also disclosed.
