Abstract: The gear unit for a delivery pump installed in a deep borehole has a toothed gear unit with a pinion located on input shaft and a gear wheel engaged with the pinion, which gear wheel is located on a vertical output shaft driving the delivery pump.  The gear unit is designed as a right-angle unit with a conical pinion gear located on the input shaft and a bevel gear located on the output shaft. Located on the input shaft is a gearwheel which together with a second gearwheel forms a gear pump which conveys fluid in a direction opposite the operational direction of rotation of the gear unit.

Abstract: An insertable stent (10) is provided for joining together, and facilitating healing of adjacent tissues (18, 20). Typically, the tissues are mammalian tissues. The inserted stent is made from completely non-toxic, bio-compatible and blood compatible materials. Each of the tissues employed herein defines an internal cavity (22). The insertable stent body defines a bore. The bore permits fluid to pass through the inserted stent body (12). In use, the inserted stent (12) is introduced into the internal cavities of the tissues (22). The inserted stent body fits within the confines of, and in contact with, each of the adjacent tissues. Typically, at least a portion of the inserted stent body (l2) is fusible to the adjacent tissues (18, 20) for facilitating healing of these tissues.

Title: Supervisory control plane over wavelength routed networks
Inventor: WANG GUO QIANG Q
IPC: H04B10/20
Filed: 2001-04-09
Granted: 2012-01-31
Abstract: A dedicated IP-based wavelength routing/signaling control plane for optically switched network, is provided. The IP-based control plane is an out- band routing/signaling mechanism and does not require optical-electrical- optical (OEO) conversion. The control plane can accommodate the various network topologies of the data plane and if one of the supervisory, or control channel fails, the IP-based control plane can re-route the traffic to destination. Using non-broadcasting addressable protocols the control plane selects a different path to re-direct the control information without declaring the whole communications trail down and without affecting the client traffic over the data path.

Title: Rotary steerable drilling tool
Inventor: NOE PAUL
IPC: E21B7/06
Filed: 2001-04-27
Granted: 2010-04-06
Abstract: The device contemplated provides a method for positioning the drill bit in a drilling operation to achieve small changes in hole angle or azimuth as drilling proceeds. Two different positions are available to the operator. The first is a straight ahead position where the tool essentially becomes a packed hole stabilizer assembly. The second position tilts the bit across a rotating fulcrum to give a calculated offset at the bit-formation interface. The direction that the bit offset is applied in relation to current hole direction is controlled by positioning the orienting pistons prior to each drilling cycle, through the use of current MWD technology. Components of the tool comprise a MWD housing, upper steering and drive mandrel, non-rotating position housing, lower drive mandrel splined with the upper mandrel, rotating fulcrum stabilizer and drill bit.

Title: Enhanced system for construction of adenovirus vectors
Inventor: GRAHAM FRANK L
IPC: C12N15/861
Filed: 2000-03-03
Granted: 2010-05-11
Abstract: In the present invention, viruses, plasmids or both are constructed which contain viral DNA, either at least one head-to-head ITR junction, recombinase recognition sites positioned such that site-specific recombination between recombinase recognition sites in separate plasmids results in generation of infectious viral DNA at high-efficiency in cotransfected host cells that have been engineered to express a site-specific recombinase, or both.  Because of the high-efficiency and specificity of the Cre enzyme, the FLP enzyme, or both, suitably engineered plasmids can be readily recombined to produce infectious virus at high--efficiency in cotransfected 293 cells, without, at the same time, producing wild-type adenovirus, with the attendant problems for removal thereof. Use of recombinases besides Cre or FLP, and recombinase recognition sites besides lox or frt sites, and use of cells other than 293 cells are also disclosed and enabled, as are kits incorporating the site-specific vector system, as well as compositions and methods for using such compositions as vaccines or in gene therapeutic applications. Enhancements in the efficiency of both site-specific and homologous recombination are provided by inclusion of at least one head-to-head ITR junction.

Granted: 2009-09-29
Abstract: A device such as for example an elec-tronic medical device (2) has a memory (6b) that has prestored therein a number of programs or routines for performing various functions. Some of those functions are optional functions that were not enabled when the equipment was put into service. If the user of the equip-ment desires thereafter to activate any one of those op-tional functions, an options card (20) that has a number of memory blocks (20a-20n) each specifically config-ured to enable one of the prestored optional functions is sent to the user. The user can then insert the options card (20) into a receptacle (16) integrated into the de-vice and, upon power up of the device, elect a menu (24) for enabling the desired optional function(s) prestored in the device. The options card (20) may be configured to have a count number that indicates the number of de-vices the card may be used to enable or diseable mul-tiple optional functions prestored in the device. When returned to the manufactorer, given that the serial num-bers of the machines to which the options card (20) was inserted are recorded therein, the manufacturer can eas-ily keep tab of the status of those machines in the field that had had optional functions enabled/disabled.

Granted: 2009-12-22
Abstract: In a method of fabricating a tuning door for resonant cavity, firstly contact fingers are formed around the edge of a conductive plate and the plate is then fixed to a support by, for example, double sided adhesive tape. The conductive plate is part of the interior surface of the resonant cavity. The fingers may be formed in one operation, for example, by photo etching and are fully integral with the active surface to give optimum electrical conduction between them. Other types of high frequency apparatus where contact fingers are used to provide electrical conduction between a moveable wall and an adjacent conductive surface may also make use of the invention.

Abstract: A communication device is provided which is intended to aid farm workers in the coordination of harvesting and hauling vehicles in the field during crop harvesting operations. This communication device consists of a transmitter and receiver which are mounted at convenient points within the harvesting vehicle and produce hauling truck respectively. The receiver contains four lighted directional arrows representing directional changes of forwards, backwards, left, and right. The transmitter contains four buttons that correspond in location and function to the directional arrows on the receiver. Thus, when a button on the transmitter is depressed by the harvester operator, the corresponding directional arrow on the receiver will light up signaling the truck driver to make a change in the position of his truck relative to the harvester.
