Filed: 1998-04-22
Granted: 1999-08-05
Abstract: An apparatus for identifying components associated with the liquid in an electrically non-conductive container utilizing a pair of electrodes. The container extends along a particular dimension such that the first electrode is placed adjacent the exterior of the container and at least a second electrode is placed adjacent the exterior of the container in spaced configuration from the first electrode and along the particular dimension of the container. A generated output signal is coupled into the liquid via the first electrode. The output signal is coupled to the second electrode after passing through the liquid component. The output waveforms are analyzed to determine the electrical characteristics of the liquid in order to identify a component within the container. <IMAGE>

Title: Heat exchanger and method of constructing same
Inventor: UNGER REUVEN Z-M
IPC: F28F1/10
Filed: 2000-08-03
Granted: 2003-08-21
Abstract: A method of forming a heat exchanger apparatus on a housing wall. The heat exchanger includes inner and outer annular rings. The rings have heat radiating, high surface area fins attached on oppositely facing surfaces. The inner ring has a radially outwardly facing surface that abuts the interior surface of the housing sidewall. The outer ring has a radially inwardly facing surface that abuts the exterior surface of the housing sidewall. When displaced longitudinally along the ring axes, which are coincidental, the sidewall is clampingly engaged therebetween, and an excellent thermal flow path is formed. Heat transferred into the inner fins from a working gas is conducted to the inner ring, through the sidewall, into the outer ring, then into the outer fins. Air impinging upon the outer fins absorbs the heat from the outer fins.

Granted: 2005-10-26
Abstract: The cooling system involves a chamber consisting of inflow and combustion zones. High-temperature gas flows into the latter zone, where it is mixed with fuel and ignites. Effusion and convective systems are used for these zones respectively. The combustion zone can be first cooled by contra-flow, using air (10) which then passes to the inflow zone. The operating gas (8) and fuel (6) can be mixed in the inflow zone, forming a flame front (13) at the connection to the combustion zone, the front being stabilised by a step (15) between the zones. Turbulence inducing components (7) upstream of the fuel inlet can generate a reverse-flow zone at the front, these being effusion-cooled.

Abstract: Molded, one-piece articles having selected surfaces suitable for adherent metallization, molded, metallized, one-piece articles, and processes for making the said articles are disclosed. The molded one-piece articles may be formed by molding into a first mold cavity a first portion of the article using a first electrically insulating material which is adhesion promotable by an adhesion promotion process and is catalytic for adherent metallization, or is capable of being rendered catalytic for adherent metallization by an activating process; inserting the first portion into a second mold cavity; and molding into the second mold cavity a second portion of the article using a second electrically insulating material, leaving selected surface areas of the first portion exposed. The second material is resistant to the adhesion promotion process employed for the first material, or is non-catalytic for, and incapable of being rendered catalytic for, adherent metallization by the activating process employed for the first material. The exposed surface areas of the first portion of the article may then be metallized, for example, by electroless deposition to form the metallized one-piece article.
Patent JP-3923208-B2 (JP)
IPC: H04L12/28
Filed: 1999-03-04
Granted: 2007-05-30
Abstract: In a radio frequency communications system, a data carrier activation method is implemented such that the carrier is switched off when no data is available for transmission. If repeated signalling information is required to be transmitted, only a predetermined number of repeats is transmitted before the carrier is switched off. The data input for transmission are compared with an idle sequence with different bit alignments to detect the presence of idle signalling, and the carrier is switched off if a match is found. When more user data is received, the carrier is switched on and frames (SM) are transmitted in synchronization with the timing of frames (SM) transmitted before the carrier deactivation. After carrier reactivation, a constant power preamble (P) may be transmitted to assist in level control in the transmitter (27; 40).

Abstract: The invention relates to a sliding rotor motor having a stator and a sliding rotor which is connected to a shaft and can slide axially relatively with respect to the stator against the force of a braking spring, the shaft being borne in bearing plates of a motor housing and the sliding rotor being supported in a rotationally fixed manner on the shaft by means of a deformation element which is attached on the shaft and transmits the torque, the deformation element having a frame with attachment points located on its edge, in each case two of which attachment points are connected to an extension of the sliding rotor or to driver arms of a supporting ring. In order to design a sliding rotor motor such that the deformation element permits a relatively large axial sliding movement of the sliding rotor with precision requirements which are not stringent it is proposed that the deformation element consist of two frames (17, 17a), one (17a) of which is connected with two of its attachment points (17b) to a connecting plate (19) (which is connected to the extension (31) of the sliding rotor), the other frame (17) being connected with two of its attachment points to the driver arms (15a) of the supporting ring (15), and both frames being connected to one another, via a transmission element (18), with their respectively remaining attachment points (17c).
