Abstract: A single breath induction anesthesia apparatus for anesthetising a patient, comprises a gas delivery system for delivering at least one gas to the patient, an oxygen supply system for providing oxygen, and an oxygen/anesthesia gas supply system for mixing oxygen and at least one anesthesia gas at a preset optimum ratio sufficient to cause anesthesia of the patient with a single breath, thereby providing an oxygen/anesthesia gas mixture. The apparatus of the invention further includes a valve for providing selective gas flow communication between the oxygen supply system and the gas delivery system or between the oxygen/anesthesia gas supply system and the gas delivery system. The valve is operable for first establishing gas flow communication between the oxygen delivery system and the gas delivery system to deliver oxygen to the patient and permit pre-oxygenation thereof, while inhibiting gas flow communication between the oxygen/anesthesia gas supply system and the gas delivery system to allow the oxygen/anesthesia gas mixture to reach the preset optimum ratio, and thereafter establishing gas flow communication between the oxygen/anesthesia gas supply system and the gas delivery system to deliver the oxygen/anesthesia gas mixture to the patient and permit single breath induction anesthesia thereof, while inhibiting gas flow communication between the oxygen supply system and the gas delivery system.

Abstract: In three-phase applications, the direction of rotation can be determined fro m signal flows in the phase conductors, usually on the basis of indicator diagrams. According to the invention, the individual phases are traced at given time periods and the measuring values or the interpolated approximatio n values or just the signs of the values are evaluated by means of an evaluati on algorithm in order to determine the direction of rotation at at least two points in time. In addition to the basic method, preferably half-wave rectified signal flows from individual phase conductors are evaluated according to an ideal sinusoidal flow. The inventive method can be advantageously used in conjunction with a digital overload relay to determin e the direction of rotation, whereby an available digital signal control devic e and/or signal processing device is used.

Abstract: A headrail designed for powered coverings for architectural openings comprises a housing defining an interior that conveniently hides a battery holder, a signal-receiving system, and an electric motor used to adjust the configuration of the covering. The headrail also hides improved hardware for mounting the motor and, in the case of coverings comprising tiltable elements, improved hardware for mounting a tilt rod. Additionally, in the case of coverings comprising tiltable elements, the headrail hides improved hardware for adjustably attaching the tiltable elements to the tilt rod in a manner that prevents, over-rotation of the tiltable elements. The battery holder may comprise a battery magazine or a battery carrier removably mounted in the headrail housing. The batteries may be inserted into or extracted from the battery holder through an opening in a bottom wall of the headrail housing. A swingably mounted trap door may selectively cover or uncover the opening. The battery carrier slidingly engages, through the opening in the bottom of the headrail housing, a battery carrier housing that is mounted within the headrail housing. The signal- receiving system includes an exposed signal receiver for receipt of remote-control signals. The present invention also provides a tilt control system with an inexpensive and effective clutch to prevent over-winding of cords onto a control shaft (e.g., a tilt rod) used to control tiltable elements of the covering. The preferred tilt control system also minimizes torque on the motor or other mechanism used to drive the control shaft.

Title: Stimulating fluid production from unconsolidated formations
Inventor: BRUMLEY JOHN L
IPC: E21B43/26

Abstract: The present invention provides methods of stimulating fluid production from an unconsolidated formation penetrated by a wellbore while preventing the migration of formation sand with fluids produced from the formation. The methods basically comprise the steps of injecting a liquid composition into a portion of the formation surrounding the wellbore which converts into a gel-like substance and plugs the permeability of the injected portion of the formation, but allows the injected portion to remain flexible and resist breakdown due to pressure cycling therein, creating at least one fracture in the formation extending from the wellbore through the plugged portion of the formation into an unplugged portion thereof and depositing hardenable resin composition coated proppant in the fracture and causing the resin composition to harden and consolidate the proppant into a hard permeable mass.

Abstract: A steering apparatus of a vehicle having a steered tire wheel steered in correspondence to an operation of a steering wheel is disclosed. A first sensor detects an actual position indicating a present rotational position of the steering wheel. A second sensor detects a wheel angle of the steered tire wheel. The steered tire wheel is driven by an electric type drive apparatus. The drive apparatus outputs a power output for operating the steered tire wheel in correspondence to a steering wheel operation. When a deviation exists between the actual position of the steering wheel detected by the first sensor and the wheel angle of the steered tire wheel detected by the second sensor, a first compensation for compensating the actual position of the steering wheel so as to make the deviation small is executed by controlling the power output of the drive apparatus.
