Title: Water-soluble, polymer-based reagents and conjugates comprising moieties derived from divinyl sulfone
Inventor: LIHME ALLAN O F
IPC: C08L5/00
Filed: 1992-06-29
Abstract: Water-soluble reagents and conjugates which are particularly well suited for use, for example, in biologically relevant de-tection, quantification and targetting procedures, e.g. in the fields of immunohistochemistry, detection of immunoreactive species, antibody immobilisation, separation or purification; DNA hybridization tests and flow cytometry, are based on a polymeric carri-er molecule having moderate to high molecular weight and to which are covalently attached one or more moieties derived from divinyl sulfone, each of which moieties is attached to the carrier molecule via a covalent linkage formed between one of the two vinyl groups of a divinyl sulfone molecule and a reactive functionality an the polymeric carrier molecule. In reagents of the inven-tion, at least one such attached moiety in its attached state has the remaining vinyl group free and capable of reaction with a mo-lecular species having a functional group, e.g. a hydroxy group or a thiol group, which is reactive towards the free vinyl group. Such a reaction results in the covalent attachment (conjugation) of the molecular species to the polymeric carrier molecule via a linking group derived from divinyl sulfone, the resulting conjugate being an example of a conjugate of the invention. Preferred water-soluble carrier molecules are polysaccharides, particularly dextrans.  The molecular species, of which more than one type may be attached to a carrier molecule, may, for example, be selected from antigens, antibodies, haptens, gene probes, hormones, enzymes, drugs, dyes, fluorophores and radioactively labelled substances.  Methods are provided for the preparation of reagents and conjugates of the invention.

Title: Method for remotely determining operability of motor operated valves
Inventor: LEON ROBERT L
IPC: F16K31/04
Filed: 1994-06-02
Abstract: A method is disclosed for determining operability of a motor operated valve combination including a valve having a valve stem, a valve disc, a valve seat, and a motor operator having a motor drive interconnecting the motor to the valve stem for movement of the valve disc toward and into engagement with the valve seat to close the valve and a control switch for deactivating the motor. The method comprises the steps of sensing the real motor power of the motor as a function of time during valve closing with zero differential pressure applied to the valve at a first time. From the sensed information, the rate of motor power build-up is determined after the onset of valve wedging during valve closing at the first time. The real motor power of the motor is again sensed as a function of time during valve closing with zero differential pressure applied to the valve at a second time which is subsequent to the first time. The rate of motor power build-up after the onset of valve wedging during valve closing at the second time is determined from the sensed information. The rate of motor power build-up after the onset of valve wedging at the first and second times is compared as an indication of lubrication change within the valve between the first and second times.

Patent CA-2133720-A1 (CA)
Inventor: HOWETH D FRANKLIN
IPC: F16L27/093
Filed: 1994-10-05
Abstract: An improved rotary joint construction is produced by eliminating the external drive mechanism used for installing and removing such joints.  An internal drive mechanism is provided within the bearing area of the stem which does not alter rated flow volume and which does not add to the length of the stem.  The internal drive mechanism comprises a socket in the end of the stem which allows the joint to be installed or removed without using special tools. A more compact shorter joint can be produced without reducing the distance between the seals and without reduced rated flow volume and without reducing the contact area of the bearings between the stem and barrel. Alternately, a joint with substantially increased bearing contact area and a longer barrel can be produced without increasing the stem installation clearance height and without reducing the interseal spacing flow passage geometry and subsequent rated flow volume. The longer bearing surface and a longer barrel provides longer life by reducing the maximum possible gap in the seal area as a result of misalignment caused by side loading of the barrel and reduces wear. The increased length of the bearings and barrel permit a substantial increase in operating pressure without undesirably extruding the seals.

Title: Method and apparatus for determining depth of drill cuttings
Inventor: GEORGI DANIEL T
IPC: E21B47/04
Filed: 1994-03-28
Abstract: A method and apparatus for identifying cuttings (20) from a wellbore (18) are provided. The cuttings are segregated through a screen assembly (33) where they can be identified by measuring emissions such as alfa, beta, or gamma particles which emanate from the cuttings via a collector or storage vessel (40). A continuous wellbore profile of the emissions from cuttings can be constructed by measuring the emissions taken from different locations in the wellbore, and by documenting such emissions. The effects of cutting dispersion caused by differing particle sizes can be reduced by collecting cuttings of an intermediate size (68) for analysis.  The profile of the intermediate size cuttings can be compared with a well log to identify the original elevation of the cuttings within the wellbore.
