Abstract: A self optimizing device for controlling a heating unit in a manner so as to improve the energy efficiency of the heating unit using an autocalibration processor. The heating unit employs a heating medium that is heated by the heating unit and which transfers the heat into an ambient atmosphere outside of the heating unit. The heating unit has an on-state initiated when a characteristic of the heating medium representative of the heating capacity of the medium decreases below a minimum level, and an off-state initiated when the characteristic of the heating medium reaches a maximum level. The controller includes an input element, an output element, a time-measuring element, and a processor. The input element receives a signal from a sensor, the signal indicating the heating medium characteristic representative of the heating capacity of the heating medium. The output element signals the heating unit to begin its on- state. The time-measuring element measures an off-time, the off-time being the length of time from initiation of the off-state of the heating unit until the characteristic of the heating medium decreases below the minimum level. The processor determines a delay time and for signaling the heating unit to delay initiation of the on-state by the delay time amount, the extension of the off-time resulting in an energy savings over an undelayed initiation. The processor further comprising an autocalibration processor for determining a delay time that results in optimum energy savings.

Abstract: A weather resistant commodity stockpile and collection pond covering system made up of a plurality of sheets joined together in waterproof seams. A  plurality of flexible cords are tightly encapsulated and fixed in each sheet at spaced apart locations within thermally welded prayer seams and utilized for retention of the cover system and the hanging of ballast bags. The peeling stresses on the prayer seams are transferred as shearing stresses to lap seams formed by welding choker strips to the cover sheets on either side of each prayer seam. Side cords encapsulated in edge seams along side edges of adjacent sheets are abutted together and secured by flexible ties to form joints between sheets. Those joints are made waterproof by edge flaps attached to the sheets which are extended over each joint and sealed to the face of an adjoining sheet.

Abstract: A heating system for heating liquids, stored in a tank at low ambient temperature, has a heating chamber with an inlet and an outlet for convectively flowing liquid past a flameless heater. Cold liquid is drawn through an inlet line, from the tank near its base and into a heating chamber, absorbs radiant energy from the heater as it travels therethrough. Heated liquid is circulated into the tank through an upper outlet from the heating chamber and back into the tank. Preferably, the heated liquid reenters the tank through a floating discharge flexibly connected to the upper outlet so as to remain dynamically in contact with the liquid at all times, thus avoiding airlocks which would interrupt the convective flow of liquid through the heating system.

Title: Method and device for magnetic guidance, especially for tracking targets
Inventor: PERRIN JACQUES
IPC: G01S13/44
Filed: 2000-05-16
Granted: 2010-01-26
Abstract: The invention relates to a method and a device for magnetic guidance, especially for tracking targets. The guidance is carried out in relation to the axis (1) of the beam of a monopulse antenna, by means of coding in the beam space. The coding process is carried out by appropriately modulating the signals radiated by the sum pattern ( SIGMA ) and the difference pattern ( DELTA ). The receiving elements provided in the device are able to determine the position of said device in relation to the radiation pattern of the antenna, and can therefore determine its position in relation to the axis of the antenna. This position is determined by demodulating the signals received by the receiver. The invention is particularly suitable for guiding missiles or smart munitions in any quantity, for example for tracking targets.

Abstract: The clock and data regenerator comprises a control loop which is controlled by a phase discriminator (PD) and two frequency discriminators (FD1, FD2). The first frequency discriminator (FD1) enlarges the catchment range of the control loop in a known manner. The second frequency discriminator (FD2) determines the ratio of the bit rates of the clock signal (TS) which it produces itself and of the data signal (DSF). It sets the loop frequency divider (6) appropriately, and supplies a control voltage for setting the oscillator (5) until the first frequency discriminator (FD1) can carry out this function.

Abstract: A method and apparatus to encode a source data stream (42) via convolutional encoding (30). Plural encoded data streams (70 and 72) are interleaved (46a and 46b) and transmitted on plural transmission channels (66 & 68). Data groups (36a and 36b) generated via convolutional encoding (30) are interleaved via time-interleaving functions (46a and 46b) to disperse selected bits within puncture groups of the data groups (36a and 36b), bits (32) in between data groups, and bits (32) in selected sets of data groups to facilitate reconstruction of the source data stream (42) from at least a portion of the interleaved data stream received on at least one transmission channel (66 and 68). The time-interleaved functions (46a and 46b) are selected to facilitate reconstruction of the sourve data stream (42) from one transmission channel (66 and 68) following continuous blockage. Subsets of bits of puncture groups are selected to allow reconstruction of the source data stream (42) from more than one of the tranmission channels (66 and 68) using a minimum number of subsets. Multiple combinations of subsets can be received on both transmission channels (66 & 68) to reconstruct the source data stream (42) following blockage of one channel. Decoding is performed via a Viterbi decoder.

Abstract: An invention relates to a contact lithography device and comprises a soft X- ray source (preferable as an X-ray tube 1 with a rotating anode), a half lens 2 for a divergent radiation of this source transforming to a quasi-parallel one (the said lens includes a set of channels for a radiation transporting with total external reflection, the said channels are oriented along a generatrix of barrel-shaped surfaces), th e means for placing a mask 3 and a substrate 4 with a resist 5 applied on it (the said means are placed on the output face side of a half lens 2), and an absorbing filter 6 for smoothing a nonuniformity of a beam intensity of an emergent radiation of a half lens, presenting in intensity decreasing as from the center to the periphery of a beam. An absorbing filter 6 is placed between the radiation source 1 and the input face of a ha lf lens 2, and a relationship of cross sizes of a half lens and its focal distance from the input side is chosen so that to provide a capture angle of a source radiation in the following limits: 0,7/E1.5 .ltoreq. .PSI. .ltoreq. 1.3/E1.5, where .PSI. is an angle of a radiation capture [rad]; E is radiation energy of the used source [keV]. The reflecting surface of the channels for a radiation transporting is made of a material which includes elementswith an atomic number not more than 22, and radiation energy of the used source is 0,6-6 keV. Owing to the increased capture angle and an absorbing filter placing before the input of a half lens, efficiency of a source radiation using increases and, simultaneously, an area of a plate-substrate under processing magnifies and lens longevity increases.

Abstract: Methods for acidification of soapstock using acids produced by fermentation with acidogenic bacteria and recovery of acidulated fatty acids are disclosed. Soapstock is advantageously acidified by fermentation of endogenous soapstock nutrients and added nutrients under controlled conditions using acidogenic bacteria. The nutrients may include carbohydrate, nitrogen, phosphorous, sulfur from defined or undefined sources. The acidification reaction avoids the use of strong acids for the treatment of soapstock, minimizes wastewater contamination with salts and produces potentially valuable by-products including lactic acid, acetic acid, glyceric acid and nutrient rich microorganisms.
