Title: Packing-seal for boreholes
Inventor: TOON DONALD A
IPC: E21B33/127
Filed: 1987-11-09
Granted: 1991-11-12
Abstract: PACKING-SEAL ASSEMBLY     Abstract of the Disclosure The packing-seal is shown in use in a borehole as a level-isolating seal for a groundwater sampler.  The packing-seal shown includes an expandable annulus (63) of Dowell (TM) water-expandable material. Surrounding that is a pressure-sleeve (61) of rubber. A sheet (64) of woven Kevlar (TM) is wrapped circumferentially around the sleeve and the Dowell annulus, such that the ends (67,68) of the Kevlar sheet overlap. Outside the Kevlar is an outer rubber sleeve (69). Upon expansion of the packing seal to fill the borehole, the Kevlar sheet unwraps to allow the Dowell to expand without restraint. Once the packing seal has filled the borehole, the Kevlar sheet is prevented from unwrapping further. If the borehole contains a fissure (71) the Kevlar provides a rigid bridge over the fissure, and prevents the packing-seal from ballooning out into the fissure.

Abstract: DEVICE FOR THE FORMATION OF A CONNECTING  TRANSITION BETWEEN TWO PERPENDICULARLY        ADJOINING SURFACES                    ABSTRACT OF THE DISCLOSURE          A device is disclosed for forming a connecting transition between two perpendicularly adjoining surfaces, of which at least one surface is provided with a rigid covering, in particular ceramic tile.  The device allows for compensa-tion of the varying stresses occurring in the surfaces bounding the joint combined with adequate sealing of the area of transition.  The device is intended to find application in particular as a connecting transition between the edge of a bathtub and the adjoining wall and consists of a single-piece plastic angular profile.  A sealing strip with a softened sealing lip is molded onto a leg of the angular profile which is formed of hardened material so as to extend the leg.  The sealing lip has an adhesive profile arranged on its outer side in the lengthwise direction of the angular profile.  By virtue of its elasticity, the molded sealing lip of the single-piece profile is biased against the surface to be sealed.  Because the sealing lip is kept connected to such surface by an adhesive connection, it always acts against such surface in a sealing manner.

Granted: 1993-04-20
Abstract: ABSTRACT         Method and apparatus for logging a borehole of the type in which an acoustic energy signal scans the borehole wall at a plurality of different depths thereby generating signals reflected from a reflecting boundary which are indicative of the condition of the reflecting boundary.  A downhole microcomputer generates a sync signal for firing a transducer thereby directing an acoustic pulse toward the borehole wall.  The transducer is rotated by a stepper motor.  The computer synchronizes the number of transducer pulses with the number of stepper motor pulses thereby generating a constant number of transducer pulses per motor revolution.  Reflected acoustic energy generates an electrical pulse which is amplified and summed with a signal relating to the rota-tional orientation of the transducer and the occurrence of the transducer firing pulse.  The summed signal provides information relating to the condition of the reflecting boundary and may be used to generate a video image thereof.            GMB:tb

Title: Search controls allowing a user to use a keyboard and display to select from a plurality of entries
Inventor: WEINER JONATHAN A
IPC: G06F3/048
Filed: 1988-10-21
Granted: 1992-05-19
Abstract: Abstract An improved apparatus and method for selecting entries within a plurality of entries is presented.  The preferred embodiment of the invention includes a search control processor which causes an edit box and a list box to be displayed on a display.  In the list box is displayed a subset of entries from a plurality of entries.  As letters are typed on a keyboard, the letters are displayed in the edit box.  The search control processor causes a first entry from the plurality of entries to be highlighted when the first letter(s) of the first entry match the letters displayed in the edit box and when the first entry in in alphabetical order before any other entry from the plurality of entries whose first letters(s) match the letter(s) displayed in the edit box.  When a user presses "ENTER" or some other designated key on the keyboard the search control processor selects the entry highlighted on the screen.  Since often the list box is not sufficiently large to display all entries in the plurality of entries, when the first entry whose first letter(s) match the letters in the edit box is not displayed, the search control processor will cause the list box to scroll so that the first entry is displayed. Also if the first letter(s) of no entry from the plurality of entries matches the letter(s) in the edit box, the search control processor will cause the list box to be scrolled to the top of the list of entries, and depressing the "ENTER" key will have no effect. Alternately, depressing the "ENTER" key could result in an error message.
