Title: Unplanar non-axisymmetric inserts
Inventor: SOUTHLAND STEPHEN G
IPC: E21B10/567
Filed: 1999-07-05
Granted: 2004-12-14
Abstract: Cutting elements for incorporation in a drill bit are provided having a body having an end face interfacing with an ultra hard material cutting layer. A main depression having a nonplanar surface is formed on the substrate and extending to the edge of the substrate subjected to the highest impact loads during drilling. This edge is immediately below the edge of the cutting layer which makes direct contact with the earth formations during drilling.  The main depression is formed by forming a plurality of secondary depressions or steps such that depth of the main depression decreases in a radial direction towards the edge of the cutting element. An ultra hard material layer is bonded to the end face of the cutting element body such that the cutting layer is the thickest over the main depression. Consequently, the cutting layer edge making contact with the earth formations during drilling has an increased thickness.

Abstract: An osmotic delivery system flow modulator assembly, an osmotic delivery syst em with a flow modulator assembly, and a method of assembling an osmotic delivery system. The osmotic delivery system flow modulator assembly includes a body having a hole locate d through the body and communicating two opposing ends of the body. The use of the osmotic delivery system flow modulator assembly lessens the chance that air or gas pockets will form in t he enclosure of the osmotic delivery system during assembly of the system. Because less air is within the osmotic delivery system, performance of the system is enhanced. Use of the flow modulator assembly also lessens the chance that beneficial agent will be wasted during assembly of t he osmotic delivery system.

Abstract: A pivotable abduction abutment support for a wheelchair or the like is disclosed. The support of the invention has a base member adapted to be fastened under the seat of the wheelchair or the like. The support also has a rod having two opposite ends, one end being mounted about a first pivot located on the base member and having a pivoting axis parallel to a front edge of the seat, and the other end having an abutment fastened to it. The rod can pivot between an upstanding position where the rod extends upwardly and substantially vertically, and a released position where the rod extends downwardly. The support further includes a releasable locking mechanism for releasably locking the rod in the upstanding position, which consists of (i) a retaining portion for engaging the front surface of the rod, the retaining portion lying above the first pivot in order to lock the rod in the upstanding position, (ii) at least one arm extending rearwardly from the retaining portion and having a distal end mounted about a second pivot located on the base member rearwardly of the first pivot, and (iii) a spring for biasing the retaining portion against the rod. By manually pivoting the retaining portion away from the rod, the rod is released and free to pivot downwardly. When the rod is pivoted from the released position to the upstanding position, the spring automatically pivots the retaining portion towards the rod to engage the front surface of the rod and thereby lock the rod in the upstanding position. Alternatively, the retaining portion can be adapted to pivot away from the rod about a pivoting axis parallel to the one of the rod or about a vertical pivoting axis.

Abstract: A sand sleeve and method of use of the same. The sand sleeve has a tubular body with a plug seat at a second end to accommodate a removable plug and shiftable sleeve at a first end that can be shifted to an open position to permit fluid flow, while the removable plug is in place. The sand sleeve is inserted into a well with the shiftable sleeve in a closed position and the tubular body in an orientation where a first end is above a second end. The shiftable sleeve is shifted to the open position with the removable plug engaged with the plug seat. This permits entry of oil and gas into the well from a formation through the radial flow openings, while the removable plug prevents fluids from lower formations from flowing through the central flow channel and intermingling. Flow turbulence through the radial flow openings keeps sand from settling on the removable plug.

Abstract: A device for pivotable and slidable suspension of sheets (5), such as window-panes for glazed verandas or balconies. The device has an upper and a lower rail, which are arranged in parallel with each other. The rails have transversely of their longitudinal direction a hollow section with a longitudinal slot on the side facing the other rail. On each of the sheets, an upper and a lower fixing element are arranged, which via the slots engage the rails. The lower fixing element has in its lowermost portion a spherical part which rests against a sliding surface in the lower rail section to enable both a sliding and a pivoting motion. Both the upper and the lower fixing element are cylindrical in the portion which extends through the slot in each rail, the diameters of the cylindrical portions being slightly smaller than the width of each slot to absorb horizontal forces in the contact between the cylindrical portions and the sides of the slots and simultaneously allow a relative vertical motion between rail and fixing element.

Abstract: A reference signal generation portion generates a reference signal independently of a repetition cycle of a signal under test. A frequency measuring portion measures a repetition frequency of the signal under test by using a reference signal from the reference signal generation portion. A sampling frequency setting portion computes and sets a value of frequency of a sampling signal which can obtain a desired delay time with respect to a phase of the signal under test based on a value of a repetition frequency measured with the frequency measuring portion. The sampling signal generation portion uses a reference signal from the reference signal generation portion and the value of the frequency set by the sampling frequency setting portion to generate a sampling signal having a cycle corresponding to the frequency.

Abstract: The invention concerns a heating system and a method for controlling a heating system. The heating system has several heating devices with valves, controlled in dependence of the temperature, in different rooms, the heating devices being supplied by a supply device (18) with an adjusting member (16), which acts upon a supply temperature, a control device (27) being provided, which activates the adjusting member (16). A heat requirement in the rooms (2 to 5) is detected, and the supply temperature is adapted accordingly.        It is endeavoured to keep the energy consumption low.        For this purpose, a counter (28) detects the number of rooms (2 to 5), in which a heat requirement exists. The supply temperature is increased by a value, which corresponds to a product of the number and a predetermined first temperature difference, when the number is higher than zero. When the number is equal to zero, the supply temperature is decreased by a predetermined second temperature difference.

Abstract: The invention is directed to a method for cell selection in a cellular telecommunication system. According to the invention, cell identification information is attached as a parameter to an RRC message initiating the state change of the mobile station to the cell-connected state. Advantageously, the network selects a cell to be suggested as the cell for use by the mobile station in the cell-connected state, and the network indicates said cell by attaching cell identification information as a parameter to said RRC message. Consequently, the mobile station may make the final selection of the cell, and indicate the selected cell to the network by attaching cell identification information as a parameter to a second RRC message, such as the response message to the RRC  message initiating the state change.
