Abstract: A threaded insert (10) made of wire is disclosed for inserting into a threaded bore (11) of a workpiece (12). A cylindrical body with several spiral windings has at least one insertion zone which is curved inwards in the radial direction, starting from the outer diameter (d) of the cylindrical body, and extends through a circumferential angle of about 360~ to 720~. This makes it easier to mount the insert into a threaded bore of the workpiece. Hitherto required special tools can be dispensed with, as the disclosed threaded insert made of wire can be easily inserted into the threaded bore and screwed therein with a simple tool.

Abstract: This invention concerns a process and equipment for producing precipitated calcium carbonate. According to the process, limestone is burnt at a high temperature to form calcium oxide and, thereafter, calcium carbonate is formed from calcium oxide in the presence of water and carbonate ions and the formed calcium carbonate is recovered. The formation of the carbonate may be performed by carbonating calcium oxide with carbon dioxide gas in the presence of water or water vapour, or by reacting calcium oxide with soda solution. According to the invention calcium oxide is converted to calcium carbonate without separate slaking and essentially without intermediate storage, in particular without intermediate storage between the burning of the starting material and the forming of calcium carbonate. With the aid of the invention a quite advantageous solution in view of heat economy is achieved.

Title: Method and apparatus for controlling the liquid level in a well
Inventor: MILLS ROBERT A R
IPC: E21B47/04
Filed: 2000-04-06
Granted: 2005-10-25
Abstract: The present invention provides a method and apparatus for controlling the production rate of a rotary downhole pump to prevent well pump-off. The method includes the steps of operating the pump at a first speed less than a maximum rate of the pump until well fluid is produced at the wellhead. The operation is continued at the first speed until a first dynamic fluid level in the annulus between the production tubing and the wellbore or the well casing is stabilized. A first static load on the drivehead at the first dynamic fluid level is determined. The pump is then operated at a second speed higher than the first speed until the fluid level in the annulus is stabilized at a second dynamic fluid level. A second static load on the drivehead at the second dynamic fluid level is determined. A linear function of the load on the drivehead is determined as a function of the fluid level in the annulus. The linear function is used to calculate a critical load on the wellhead at a pump off point of the well where the fluid level in the annulus is equal to the insertion depth of the pump. The speed of the pump is reduced when the critical load is reached to prevent pump-off. The method and apparatus of the invention provides for the monitoring and control of the well pumping operation to prevent pump-off without the need for downhole monitoring or measuring equipment.

Abstract: In order to make more compact drive train and engine configurations, filter media and oil coolers are mounted within transmission oil pans and/or lubricating oil pans. Preferably, the heat exchanger is mounted on the upstream side of the filter media to cool the oil before the oil passes through the filter media and is recirculated by an oil pump. It is also preferable that both the filter media and the heat exchanger are integrally molded with a panel which is removably inserted into the oil pan to separate the oil pan into a first chamber, which is an upper chamber, and a second chamber, which is a lower chamber, so that oil drained into the upper chamber pools in the lower chamber and is recirculated back through the transmission or engine by a suction tube communicating with the lower chamber.

Abstract: A vehicle computer system has an audio entertainment system implemented in a logic unit and audio digital signal processor (DSP) independent from the host CPU. The audio entertainment system employs a set of ping/pong buffers and direct memory access (DMA) circuits to transfer data between different audio devices. Audio data is exchanged using a mapping overlay technique, in which the DMA circuits for two audio devices read and write to the same memory buffer. The computer system provides an audio manage API (application program interface) to enable applications running on the computer to control the various audio sources without knowing the hardware and implementation details of the underlying sound system. The audio manager API transfers calls made by the applications to the appropriate device driver. The computer system also supports a speech recognition system. Speech utterances are picked up by a microphone and sampled at an internal sampling rate.

Title: Processes for preparing precipitated calcium carbonate compositions and products thereof
Inventor: FREEMAN GARY M
IPC: C01F11/18
Filed: 2001-05-14
Granted: 2006-07-25
Abstract: Processes for making high quality PCC compositions, and the resulting PCC  products thereof. A precipitated calcium carbonate (PCC) composition is prepared by a process comprising the step of wet media mill grinding an aqueous slurry of PCC made by carbonation of lime milk, with the grinding being done at a low solids content in a plurality of separate grinding stages, which can done while essentially free of the presence of organic dispersant. After the multi-stage wet grinding step, the ground PCC slurry is partially dewatered in the presence of an organic dispersant in a solid bowl centrifuge. Then, the partially dewatered PCC slurry is subjected, in the presence of an organic dispersant, to fluid shearing forces created in a rotor/stator type mixer. While these three steps are advantageously used together within a single PCC process flow for optimal effect, the individual steps also can be incorporated singly or in lesser combinations thereof into different PCC manufacturing schemes to beneficial effect. The resulting PCC compositions are endowed with reduced high-shear viscosity in aqueous slurry form at high solids content and contain PCC particles of narrower particle size distribution. PCC slurries are provided that are particularly well-suited for paper coatings applications including medium and low coating weight, woodfree paper coatings, although it has wider applicability and is by no means limited thereto. As another aspect, the additional cost otherwise associated with the use of evaporative-based dehydration procedures to increase the PCC solids content in a PCC slurry or associated with the adding of dry CaCO3 pigment to build slurry solids can be reduced or even eliminated by a facile made in a decanting operation within the inventive process flow.
