Title: Tubing conveyed wellbore fluid flow measurement system
Inventor: SIEGFRIED ROBERT W II
IPC: E21B47/10
Filed: 1990-01-31
Abstract: A fluid flow measuring or so-called production logging instrument (24) for fluids produced in a well includes an inflatable packer (38) for forming a seal (40) in the wellbore (10) to require diversion of wellbore fluid through a passage formed in the instrument whereby fluid flow rate and other fluid properties may be measured. The inflatable packer (38) receives pressure fluid from the tubing string (22) and may be remotely controlled to inflate and deflate, at will, through signals conducted from the surface to the instrument by way of a cable (30) extending through the tubing string. The instrument (24) includes a main wellbore fluid flow passage in which a shutoff valve (92) is disposed for controlling the flow of fluid through the passage and which may be automatically closed or opened in response to actuation of the packer seal (40).

Title: Multi-component stabilizer system for polyolefins pigmented with phthalocyanine pigments
Inventor: KLETECKA GEORGE
IPC: C08L23/00
Filed: 1991-01-22
Abstract: MULTI-COMPONENT STABILIZER SYSTEM FOR POLYOLEFINES       PIGMENTED WITH PHTHALOCYANINE PIGMENTS                   ABSTRACT OF THE DISCLOSURE    Excellent color stabilization as well as fiber integ-rity is obtained in bright sunlight and at relatively high temperature, in polyolefine (Po) articles pigmented with phthalocyanine pigments, by combining the pigment with two `large molecule' primary stabilizers, the first a hindered amine light stabilizer (HALS) and the second a 3,5-disub-stituted-tert-butyl-4-hydroxybenzoate (3,5-DHBZ). The first contains at least one triazine ring, and each substitutable position on each triazine ring is substituted with an oxo-piperazinyl group; the second is a hindered phenol with an ester group in the para- position. Stabilization of the PO's color is obtained for as long as the PO articles themselves are stabilized by the combination of primary stabilizers. With the combination, phthalocyanine pigmented articles are not only thermooxidatively and light-stabiliz-ed, but there is exceptionally low color fade. Because fibers are extruded twice for better distribution of pig-ment, a small amount, no more than 0.1 phr of secondary melt-stabilizers, may be used. Blue- and green-pigmented PO articles in particular, so stabilized, exhibit less than a +2 change in color (color fading) due to degradation of the pigment, over exposure resulting in absorption of 1240 kjoules. Such exposure, deemed equivalent to exposure to sunlight for about 2 years in Florida at a 45° South expo-sure, of PP fibers pigmented with the combination of pri-mary stabilizers suffer essentially no loss of color due to degradation of the pigment.

Title: Hot rotary stamper apparatus and methods for metal leaf stamping
Inventor: AMENDOLA ANGEL
IPC: B44C1/14
Filed: 1991-04-15
Abstract: A continuous sheet 27 of metal leaf advanced at a constant rate is moved at variable velocity through a rotary die stamper 6, 7 such that between stamps the metal leaf moves at a velocity which is slower than the velocity of a substrate web 28; but just prior to stamping the metal leaf is accelerated by contact between the metal leaf sheet and a raised die 5 rotating at the velocity of the substrate web so that when the stamp occurs the metal leaf sheet is travelling at a velocity substantially equal to the velocity of the substrate web. Varying the velocity of the metal leaf sheet has the effect of minimizing the distance the metal leaf sheet travels between stamps which conserves consumption of the metal leaf sheet. Separate means for accelerating the leaf sheet prior to stamping and decelerating the leaf sheet after stamping may also be provided.

IPC: A62B19/00
Filed: 1991-05-02
Abstract: A filter canister assembly and process utilizes a sealant deflector to seal a particulate filter to the canister wall, even after the canister is sealed.  The canister housing has a wall and an aperture with a particulate filter disposed therein.  The particulate filter has an edge adjacent the wall, and is designed for removing particles of contaminants from a fluid, such as air, passed through the canister.  A sealant deflector includes a plurality of vanes standing proud of a support substrate, and is situated between the aperture and the particulate filter and forms a permanent part of the canister assembly.  The sealant deflector deflects a sealant in liquid state toward the wall to form a seal between the edge and the wall when the sealant is deposited on the sealant deflector while spinning. This deposits a sealant ring sealing the wall to the edge.  The sealant deflector is self-centered under the aperture, by a bow-tie shaped structure of four arms extending outward radially from the sealant deflector connected in pairs by curved braces.

Abstract: ABSTRACT OF THE DISCLOSURE     A guard for preventing in-line roller skates from rolling when the user is wearing the skates, consists of an extruded polyvinyl chloride rail which has a longitudinal groove to accept the wheels of an in-line rollerskate.  The inside walls of this groove are lined with inward facing teeth which will clamp onto a typical in-line roller skate wheel.  A retention strap over top of the in-line rollerskate boot will also ensure that the guard stays in place.          A wheel chock will be fastened into the longitudinal groove of the rail to prevent for-aft movement of the in-line roller skate within the guard.  The in-line roller skate, consists of a three, four, or five wheel combination of varying wheelbase and distance between wheel centers.  Some manufacturers offer skate platforms in which the middle wheel or wheels may be dropped relative to the ground contact plain, thus resulting in a wheel platform configuration known as a rocker.  The combinations of all the features hereafter claimed will result in an in-line roller skate guard which will be safe an easy to use.
