IPC: C09K23/00
Filed: 1991-07-25
Abstract: Described is the use of surface-active alpha-sulfo-fatty acid di-salts as ecologically compatible emulsi-fiers of the W/o type and O/W type, respectively, in fluid and pumpable drilling fluids and other fluid drilling-hole treatment agents which comprise a con-tinuous or a dispersed oil phase together with an aqueous phase and which are suitable for an environment-ally acceptable exploitation of geological resources, for example oil or natural gas deposits. The invention further relates to inverted drilling fluids based on a continuous oil phase and, present therein, a dispersed aqueous phase which, in addition to the emulsifiers, contain further conventional auxiliary agents such as thickeners, fluid-loss additives, weighting agents, water-soluble salts and/or alkali reserves. The inverted drilling fluids according to the invention are characterized in that they contain surface-active di-salts of the type indicated as emulsifier or as an emulsifier component together with an ecologically compatible continuous oil phase.

Title: Unsaturated polyester-epoxy resin network composition
Inventor: MCGARRY FREDERICK J
IPC: C08G59/50
Filed: 1993-04-16
Abstract: ABSTRACT           A unsaturated polyester resin composition is described that contains an epoxy resin reacted with an amine-terminated flexible polymer while dissolved in the unsaturated  polyester  resin  and  its  ethylenically unsaturated crosslinking monomer.  A compatible system results  from the reaction which has  a controllable modulus based on the amount of flexible polymer included in the resin.   The resin is generally transparent if unfilled and has a higher calculated fracture energy than  similar  unsaturated  polyester  resin  without modification.   The unsaturated polyester resin can be filled  with  particulate  filler  or  reinforced  with fibrous fillers.

Title: Transplanting Tool
Inventor: CARON FRANCOIS
IPC: A01C5/02
Filed: 1993-06-10
Abstract: A transplanting tool for the manual extraction and planting of seedlings.  The transplanting tool comprises, a digging tube,  a hollow plunger slidably contained within said digging tube, a stem and a transverse piece forming a handle, and a pair of foot bars extending from the outside surface of said digging tube, at substan-tially  opposite  direction  from  one  another.    The arrangement of the components therefrom, offers a clear line of sight at the center of the hollow plunger for placing the digging tube over a seedling without damaging the plant's foliage.   The angle of the foot bars is adapted to prevent strain on the user's leg, thereby facilitating altering between digging and walking motion. The transplanting tool is therefore especially suitable for extracting seedlings from rough terrains.

IPC: H04Q3/00
Filed: 1991-12-16
Abstract: A system for creating and modifying intelligent tele-phone network call processing logic trees which can be custom-ized for individual customers and created in a user-friendly vis-ual environment (10, 15, Fig. 3-5). Service primitives are de-fined as logical graph nodes (20, Fig. 2, Fig. 3) which can be visually assembled into logic trees (Fig. 5) which represent the service logic flow and which provide default values for all ser-vice options. Higher level nodes, assembled from a plurality of service primitives, can likewise be defined and stored (12, 13, 19) for later use as entities in defining yet further call process-ing logic trees. These call processing logic trees are interpreted to allow the service control point computers (17) to implement the services in the switched telephone network (18) by sequen-tially executing the specified call processing primitives. A lib-rary (12, 13, 19) of defined nodes and defined node assemblies which represent service features can thus be made available to permit graphical manipulation into complete logic trees repres-enting new services. These logic trees are then interpreted by generic programs in the service control point to actually pro-vide the described services.

Title: Hollow hub helical earth anchor with improved earth penetrating spade/pilot point
Inventor: HAMILTON DANIEL V
IPC: E02D5/80
Filed: 1994-05-09
Abstract: ABSTRACT A  lighter  weight,  high  strength  cast  screw anchor  is  disclosed which has  a hollow,  installation wrench receiving hub,  a helical,  load bearing element projecting outwardly  from the hub,  and an elongated, pointed end spade integral with and extending away from the hub.  The spade has two diametrically opposed, angu-larly disposed cutting margins located on opposite sides of the axis of the hub.  The tip section of the pointed spade is offset laterally from the hub axis, so that upon installation of the anchor,  the hub and helical  load bearing element move in an orbital path about the axis of the tip, whereas the spade moves in an orbital path after the helical element has been installed in the ground to a depth limiting its orbital movement.  The resulting anchor may be installed in dense or frozen soils with less torque and to a greater depth than heretofore available cast screw anchors.
