Patent MX-PA02007416-A (MX)
Title: Insect bait station and reservoir.
Inventor: NELSON THOMAS D
IPC: A01M1/20
Filed: 2001-01-22
Abstract: The present invention relates to a bait station comprising a base, a reservoir, a cover, and a latch. The base may be used in two different orientations and includes a first section and a second section. The first section has climbing assisting members and a cavity with a reservoir receiving area, and the second section has side climbing assisting members. The climbing assisting members and side climbing assisting members of the base provide a textured surface that enables insects to crawl into and out of the bait station more easily. The reservoir contains poisonous bait and may be placed in two different positions within the reservoir receiving area to accommodate the two different orientations in which the base may be used. The reservoir includes tapered sides with climbing assisting members. The climbing assisting members provide a textured surface that enables insects to crawl into and out of the reservoir more easily. The reservoir also includes an aperture proximate a corner of the reservoir, which provides an entrance into and out of the reservoir and reduces the rate of evaporation of the poisonous bait. The tapered sides of the reservoir also reduce the rate of evaporation of liquid bait because as the volume of the bait decreases, the surface area of the bait exposed to air flowing in and out of the reservoir is also decreased. Finally, the cover is configured and arranged to fit over the base, and the latch secures the cover to the base.

Title: Recirculatable ball drop release device for lateral oilwell drilling applications.
Inventor: ODELL ALBERT C II
IPC: E21B23/00
Filed: 2001-02-14
Abstract: Method for disconnecting tubular members and apparatus comprising upper (310) and lower housings (320) and a ball sleeve (330). The apparatus connects between tubing (150) and a drilling assembly (210). A splined connection is formed between a grooved recess (395) in the upper housing and a splined extension (450) of the lower housing. Shear screws (340) hold the ball sleeve (330) internally of the housings. To release, a ball (380) with a density equal to the density of the drilling fluid is pumped to seat on the sleeve (330) regardless of wellbore orientation. Pressure builds behind the sleeve (330), shearing the shear screws (340) so the sleeve (330) moves into the lower housing (320), thereby making the housings separable. Fluid continues flowing through recirculation ports (375) in the sleeve (330) before the housings are separated. After separation, a fishing tool grapples the extension to retrieve the lower housing (320) and drilling assembly (210). When the fishing tool attaches, flow can resume through the recirculation ports (375) to aid retrieval.
