Abstract: This invention relates to a process for the manufacture of an elongated tube, the process comprising the following steps: (a) forming a rotating temporary tube (1), the tube having a first end at which the tube is continuously produced and a second end opposite to the first end, by continuously supplying a flat, elongated metal strip to a guiding body, which guiding body is forming a helix from the strip in such a way that consecutive windings of the helix do not overlap, and helically welding the consecutive windings of the helix formed by the guiding body to each other, (b) cutting cylinders from the second end of the rotating temporary tube (1); and (c) welding the cylinders obtained in step (b) to each other to form the elongated tube. The invention further relates to the use of the elongated tube in a process for the manufacture of an elongated, multilayered tubular body.

Abstract: A system enhances spatialization in an audio signal at a receiving location. The system applies a phase difference analysis to signals received from an array of spaced apart input devices that convert sound into electrical signals. The system derives spatial or directional information about the relative locations of the sound sources. The converted signals may be mixed using weights derived from the spatial information to generate a multichannel output signal that, when processed by a remote or local audio system, generates a representation of the relative locations of the sound sources at the originating location at the receiving location.

Abstract: A "word tree" is generated by players of this board game using "consonant" and "vowel" tiles. The distribution of available consonant tiles and the unlimited availability, in principle, of the vowel tiles ("a", "e", "i", "o", "u") ensures that almost all words (more than 99%) existing in the English language can be built by a player. A "root word" is placed horizontally, by the first player in the mid-section of the board. The second and subsequent words are built off the consonant tiles already played on the board. It is akin to starting new branches off these "consonant" nodes. The generated tree is bound in a finite rectangular space. The objective of the game is to make "long" words either "new" ones or extensions of those already played. The element of chance in winning this game has been minimized. The game showcases and stimulates knowledge recognition, vocabulary building and articulation.
Patent CA-2733171-A1 (CA)
Inventor: HEGGEN OLA
IPC: F24J3/08
Filed: 2009-08-31
Abstract: The invention concerns a method for evaporation and possibly distillation of liquids by means of a heat pump. By using a heat pump (2), energy is taken from energy reservoirs (1) such as rivers, lakes, sea water, air, sun or ground heat. It is however difficult to obtain temperatures high enough to evaporate water at atmospheric conditions. According to the invention, low temperature heat is utilized by means of a heat pump by using the condenser (high pressure part) of the heat pump to evaporate liquids in an evaporator (4') at a pressure lower than the atmospheric pressure, and thus at a lower evaporation temperature. A pump or a compressor (10) after the evaporator (4') together with a pressure reducing device (9) at the inlet of the evaporator (41) ensures lower evaporation pressure. To fully utilize the heat energy from the heat pump, the liquids may be preheated in heat exchangers (5) before the pressure reducing means, or as part of the same means. To achieve higher temperature and pressure of the evaporated liquids, said liquids are further compressed by means of compressors (10), or alternatively by heating in intermediate heat exchangers (11) in order to achieve the desired temperature level. In the case of distillation, one stage will be required for each distillate. In addition to compressors (10), intermediate heat exchangers (11) and draining devices (12), pumps (13) are required to maintain desired recondensation pressure, possibly also valves (14) to insure correct dosing of residual products and distillates to collecting devices (15).

Abstract: The present invention provides hydrocarbon-based fracturing fluid compositions comprising a hydrocarbon fluid, proppant, and a small amount of water, and methods of using same. The small amount of water, preferably present at a concentration ranging from about 0.1 to 5%, causes water bridging between the proppant particulates, causing the proppant particles to agglomerate. The compositions are useful in mitigating proppant flowback in hydraulic fracturing operations and are useful in isolating one or more zones in vertical as well as horizontal wells having multiple pay zones.

IPC: A61N1/378
Filed: 2008-11-27
Abstract: The disclosed invention varies the width of the energy pulses with constant frequency and constant amplitude to regulate the amount of energy transferred from an energy transmitting device placed outside a patient to an energy receiver inside the patient. The pulse width is achieved with a modulation technique, PWMT, to control the amount of energy transferred from the external energy transmitting coil in the system to the implanted receiver. The PWMT is used to digitally vary the amount of power from the power amplifier that drives the transmitting coil. Compared to previous analog systems a PWM system is a great deal more efficient and can easily be controlled from a digital domain system such as a microprocessor.
