Patent EP-0216417-A2 (EP)
Inventor: MCGILL HOWARD L
IPC: E21B23/06
Filed: 1986-09-02
Abstract: A packer amd service tool assembly for oil or gas well preparation includes a disengageable coupling mechanism which permits the tool to be screwed into and out of the packer and which can be hydraulically disengaged so that the tool can be removed without applying torque to the tool or workstring. A releaseable ratchet mechanism is also provided in the packer for trapping the setting loads when the packer is set in the casing. The ratchet mechanism is releasable by pulling up a housing portion which cammingly engages collapsible ratchet fingers thereby disengaging the ratchet finger trapping teeth from a stationary ratchet ring.

Abstract: A method of automatic milking permitting con­tinuous electrical monitoring of milk-related values, such as milk conductivity and milk temperature, for detecting diseased cows. The method uses a claw-piece with four short-milk tubes (16-19) and teat cups, as is customary, but mixing of milk from different cow's quarters is prevented by the valves (27-30) within the claw-piece base (10). Within the base (10), the four channels from the four input nipples (16-19) each contains milk from one cow's quarter solely. Groups of electrical sensors (41) extend into each of the four channels for monitoring the milk-related values. The method relates in particular to hydraulic milking, when no air-bleed is provided upstream of the clawpiece. Suitable apparatus is described for carrying out the method.

Abstract: A skip table (200) is prepared from which a state of a subsequent symbol string and an address of one or plural symbols to be subsequently inputted can be readily determined by making reference to a set of a current symbol string search state and one or plural symbols to be subsequently inputted of the symbol string. When executing searching for the symbol string, data stored in the skip table are looked up to assure the symbol string search by inputting only a minimized number of necessary characters of the symbol string. Necessity of inputting all the characters of the symbol string for searching is eliminated and the processing speed can be increased considerably. A plurality of symbol strings may be searched for.

Abstract: A photo-mask for use in manufacturing an optical memory disc has a substrate having a disc shape and made of a transparent material, and a film deposited on the sub­strate and formed with a predetermined pattern of grooves extending spirally or concentrically to the center of the disc shaped substrate such as to leave a thin film at the bottom of the grooves, and a number of microscopic pits in the form of minute indentations with a predetermined spacing aligned along the grooves so as to substantially leave no film at the bottom of the indentations. Thus, a light which has passed through the thin film at grooves is weakened and a light which has passed through the indentations loses substantially no power, and a light applied elsewhere on the film is cut off. The photo-mask is made through the steps of depositing an opaque film on a substrate having a disc shape and made of a transparent material, impinging a first laser at places where the grooves are to be formed, and impinging a second laser at places where the pits are to be formed. The first laser is weaker in power than the second laser.

Abstract: A gas scavenger unit (50,98) educts gases away from semiconductor wafers (20) as they are withdrawn through a plenum (54) in the scavenger from their processing chamber (40) into the atmosphere. The scavenger (50,90) has a peripheral wall (52) which generally defines a plenum (54) hving two open ends. The one end (56) of the plenum (54) communicates with the processing chamber (40) and the other end (58) communicates with the atmosphere. An exhaust port (61) in the peripheral wall (52) communicates with a house gas exhaust system (62). The plenum (54) is divided into two chambers (80, 82 or 92, 94) by an apertured interior wall (70,96). The wafers (20) travel through the first chamber (80,92) and the second chamber (82,94) communicates with the house gas exhaust system (62). The apertures (76) in the interior wall (70,96) are disposed about the wafer travel path so that gases from the processing chamber and/or the atmosphere are educted into the house exhaust system (62) without flowing across the wafers (20).

Abstract: In a homing system (10) for directing an in-ground boring device (12) through the ground from its particular location (14) to a specific target point (16), an electromagnetic dipole field containing a predetermined homing signal is generated at the boring device (12) and detected by a receiving antenna (30) at the target point (16) or in a preferred embodiment where the target point (16) is below ground, at a ground level point (28) directly above or beyond the target point (16). Means are provided for producing in response to detection of the homing signal an internal electrical signal containing certain information relating to the actual path taken by the boring device (12) as compared to the path or course leading to the target point (16). The information from this latter signal is then transmitted by means of electromagnetic waves to a remote location (18) where it is used to steer the boring device (12) on a course toward the target point (16).

Abstract: A folding box of cardboard or similar material, comprising a casing having a longitudinal joint (19) and top and bottom end closures and preferably sealing membranes attached to flaps of said end closures. 
     The longitudinal joint (19) of the folding box is formed as an abutting edge joint which at least partially (22, 24, resp.) along a substantial length of the total folding box length has an extension which is not parallel to the side edges of the folding box. Especially in that case where sealing membranes exist, the joint extends the whole way out to the free cut edges of each end flap of the top and bottom end closure, re­spectively, and the cross section of the folding box is covered by a sealing membrane attached against flaps at each end of the folding box. 
     The longitudinal joint is covered by a strip, placed externally or internally or on both sides of the wall. The strip is of a thin material, preferably of a thickness around 20 - 50 µm and covers the joint at both sides thereof. 
     Preferably the strip has a grip portion (21ʹ) which, when grip­ped results in tearing up of the folding box side along per­forations (22) placed outside or inside, preferably inside, the longitudinal edges of the strip (21).
