Title: Measuring and servicing the drilling fluid in a well
IPC: E21B21/08
Filed: 1971-08-26
Abstract: This invention relates to a method and system for detecting the condition of a well. During tripping the drilling fluid in the well is controlled to provide an early warning indication of an abnormality in the well. The volume of solid materials moved during each trip is measured and a corresponding required volume of drilling fluid is determined. A measured volume of drilling fluid is delivered in order to restore in the well the drilling fluid to a reference level. The required volume is compared with the measured volume to obtain signals which are indicative of the condition of the well.

Title: Stitch shortening and tacking assembly
IPC: D05B1/24
Filed: 1978-03-09
Abstract: A stitch shortening and tacking assembly for use in a sewing machine is provided. The shortening and tacking assembly is particularly suited for use with a sewing machine wherein a fabric is advanced between a presser foot and a platen disposed in a first feeding position by a reciprocating feeder that is synchronized with respect to a rib and sewing needle. The sewing needle is synchronized with respect to the feeder and rib to stitch the fabric after the web has been advanced by the feeder. The platen is adapted to be displaced from the feed position to a stitch shortening position whereby the web is advanced through a shorter interval between sewing operations to thereby shorten the length of each stitch effected thereby. The platen is further adapted to be displaced from the stitch shortening position to a stitch tacking position whereby a portion of the platen is biased against the presser foot to thereby prevent the fabric from being advanced between sewing operations.
