Abstract: Dip measurements and investigation of geological formations traversed by a deviated borehole is carried out by means of an apparatus comprising a measuring sonde and a cartridge connected to a cable. The sonde carries four measuring pads regularly distributed by means of articulated arms which keep the pads parallel to the axis of the sonde. The opposite arms are forced to stay symmetrical in relation to the sonde. The sonde is connected to the cartridge so that its axis can depart angularly from the axis of the cartridge, enabling the latter to rest on the borehole wall. The pads have a length smaller than twice the transverse dimension D of the sonde.

Abstract: Part of the synthesis gas produced by coal gasification in an allothermically heated fluidized bed reactor is burned after removal of dust and sulfur and serves as a source of energy to heat the reactor by indirect heat exchange and to produce the steam required for the gasification process. The flue gas exiting from the heat exchanger of the reactor can be used to perform work in expansion turbines. The rest of the synthesis gas is available for use in downstream processes, such as iron ore reduction, or can be burned and used to perform work in turbines to produce electric current. The result is a process that is environmentally safer and operates with a better yield than direct coal burning or autothermal coal gasification, but requires no outside source of energy, such as nuclear power, as prior art allothermal coal gasification processes do.

Abstract: A device is provided for indicating when an intravenous needle has entered the vein through the use of a solid fiber optic (20) mounted in the needle (14) for showing visual instantaneous vein entry. The distal end (22) of the fiber optic (20) is polished to be flush with the distal point (16) of the needle. The fiber optic (20) is sized to have an outer diameter which will extend through the cannula of the needle. This polished distal end (22) reflects color, such as red blood, immediately upon vein entry and exposure to blood to the magnifying system (30,36) forming a part of the invention at the rear or proximal end of the fiber optic (20). The user observes immediate vein entry without any blood flow or exposure to blood. Other embodiments utilize the fiber optic (20) as the needle (14), thus eliminating the needle itself. <IMAGE>

Abstract: A disposable absorbent article that effectively prevents the leakage of body fluids beyond its confines. The article of the present invention comprises a body having a fluid-impermeable backsheet, an intermediate, fluid-absorbing core, and a fluid-permeable topsheet. A pair of leg cuff assemblies is attached to the body. Each assembly comprises a cuff standing portion and a cuff base portion. The assemblies are composed of two hydrophobic nonwoven layers. A first layer is composed of a spunbonded web and a second layer is composed of a meltblown fiber. The first layer extends from the free, unattached end of the cuff standing portion to the distal edge of the article defining the leg opening. The second layer is provided where needed and in weights as needed to provide maximum assembly hydrophobicity with a minimum use of material. This construction allows the cuff assemblies to form fluid-impermeable dams which prevent passage of body fluid beyond the article along its leg hole sides.
