Abstract: Air is introduced into the injection water for microbial enhanced oil recovery. The injection water is passed through an ejector where it is entrained and the oxygen subsequently dissolves in the water. In operation, the pump operates at a constant speed, pumping water to the wellhead, via the ejector. Air is drawn into the water stream at the ejector and dissolves in the water, by virtue of the high water pressure, between the ejector and the wellhead. The amount of air supplied is adjusted using the control valve and this is controlled in dependence upon the pressure in the air line measured by the pressure gauge and the pressure drop across the ejector measured by the pressure gauges. The amount of air drawn into the water is also affected by the proportion of water which passes via the bypass line, thus avoiding the ejector.

Abstract: A quick release mig gun tip comprises a contact tip having an exterior frusto-conical surface and external threads, and a gas diffuser having an internal frusto-conical surface and internal threads. The threads are preferably stub acme threads.      The contact tip is assembled to the gas diffuser by engaging their threads until the frusto-conical surfaces mate. Large currents can be conducted through the frusto-conical surfaces and the threads without causing excessive resistance heating.      The contact tip threads are designed so that assembly and release of the contact tip requires only one turn relative to the gas diffuser.

Abstract: The endless track is made of a reinforced rubber material with longitudinally spaced and transversely disposed ridges or lugs. It is particularly well-adapted for recreational snowmobiles having a single track. The ground-engaging side of the track features a tread pattern that is repeated uniformly or not over the entire length of the track. The tread pattern comprises a plurality of projecting traction lugs each having an upper edge. The internal side of the track features a plurality of protuberances called drive lugs which engage in the sprockets. These sprockets are driven by the snowmobile engine and transmit its power to the endless track. The braking power is also transmitted by the sprockets to the track. It is characterized in that the drive lugs have a pitch distance half of the pitch distance of the tread pattern therefore doubling the number of lugs engaged in the sprocket. Such tracks reduce noise and rolling resistance.

Granted: 2006-10-10
Abstract: An inexpensive and accurate device for sensing rotor position and detecting rotational speed over a broad range of speeds in an electric motor includes a sense ring magnet (200) and two analog Hall effect sensors (10$, 109, 722). The sense ring (200) is magnetized in an alternating north-south fashion with a number of poles that correspond to a number of motor field poles. The Hall effect sensors (722) are placed so that they measure magnetic flux tangential to the sense ring.  The Hall effect sensors (722) are preferably located at a distance from the sense ring where the Hall effect sensor output waveforms are substantially triangular, with a highly linear portion centered at zero flux between the minimum and maximum waveform peaks. The linear portions of the waveforms are decoded using an A/D converter and control software to provide an accurate measure of the rotor (724) position.

Abstract: The mixing element (2) is provided for a flange transition (10) in a pipeline (1) and can be mounted between two flanges (11, 12) of the pipeline. It comprises a mixing-active structure (25) which is formed by one or two vanes (25a, 25b) within a ring (20). Two mutually inclined planes (21, 22) can be defined, with the one vane being arranged on the one plane or the two vanes being arranged on the two planes. The two planes intersect at a crossing axis (23). Closed sub-surfaces (52, 51') as well as open pieces of surface (51, 520, 521, 522) of the vanes form a surface pattern (5) which is formed asymmetrically with respect to the crossing axis. Through the asymmetric shape a fluid (9) which flows through the pipeline can be deflected in such a manner that partial flows (9b) are deflected from one pipe half through sub-surfaces of the one plane (21) into the other pipe half and encounter there largely non deflected partial flows, with this also holding vice versa with respect to the other plane (22) if on the latter there is a second vane (25b) having structure elements.

Abstract: An electronic copy of a paper document, such as high school transcript, can be attached to an electronic document, such as an application for admission to an institution. The high school providing the paper document is required to have only a simple fax machine. When a student requests that a transcript accompany an electronic application, a request for the transcript is automatically generated by the applicaiton servicer and transmitted to the hight school. The request includes a return facsimile cover sheet that includes an identifier that can be automatically machine-interpreted when the cover sheet is transmitted back to the servicer with the transcipt. The identifier mark-ing is sufficiently robust that it will be machine interpretable, even after rough treatment or serial copying and transmission by the high school. Upon receipt of the transcript facsimile, the servicer automatically interprets the identifying information on the return facsimile cover sheet to identify the student and the particular admissions application for which the transcript was requested. The transcript is forwarded preferably along with application to the appropriate institution after being converted, if necessary, to a data format specified by the institution. The servicer may also store the transcript in electronic form in a secure database for subsequent transmission for a different term or to different institution. Each facsimile cover sheet is preferably "branded" with the logo of the institution to which the student is applying, although the return facsimile number is preferably a toll free number to a computer facsimile server of the servicer. Thus, the servicer can be invisible to the high school.

Abstract: A hemming machine is disclosed having a base, a nest adapted to support a part to be hemmed, a nest carrier which supports the nest and in which both the nest and nest carrier are vertically movably mounted to the base. At least one hemming die is laterally slidably mounted to the base and movable between an extended position in which the die overlies a portion of the nest, and a retracted position in which the die is spaced laterally outwardly from the nest. A lock unit selectively locks the nest carrier against vertical movement relative to the base in at least one, and preferably two positions, so that, with the nest carrier locked against movement relative to the base, inflation of a hydraulic bladder sandwiched between the nest and nest carrier displaces the nest vertically upwardly from the carrier so that the part carried by the nest is compressed against the hemming dies and performs the hemming operation. Preferably, a single drive shaft not only displaces the nest and nest carrier, but also powers the hydraulic circuit to inflate the bladder and thus upwardly displace the nest relative to the nest carrier with an amplified force required to achieve the final flattening of the hem.

Abstract: Process for the offsite manufacturing of a tubular unit coupling, for coupling double-walled tubes which comprise an outer tube or jacket and an inner tube or conductor, by means of a bell-shaped piece. The piece is manufactured from tubular sections of certain length. One of the inner tube ends is heated to be formed and subsequently machined. The coupling is subject to a thermal treatment as required for the desired grade. In order to control thermal insulation, the piece is covered with thin aluminum foils and then with ceramic fiber material in a helicoidal fashion. Subsequent steps involve covering the ceramic layer with a fiber-glass fabric thus generating an assembly which enables smooth sliding through the outer tube without breakage or displacement of the insulating layer. The insulated unit is introduced into outer tube and ends are alternately welded. The tubular unit coupling obtained by such process is also disclosed.
