Abstract: A method and apparatus (3, 60, 202, 300) are presented for mea-suring the dynamic, or alternating current, and static, or direct current, characteristics of a cable pair (2, 10, 24, 133) from one end, the local end, by utilizing an element (1, 19, 20) possessing known non-linear electrical characteristics connected across the other end, the remote end, together with methods and ap-paratus (30; 111) for connecting the non-linear element (1) across the re-mote end of the cable pair (2, 10, 24, 133) and disconnecting the non-lin-ear element (1) by means of electri-cal voltages impressed across the cable pair (2, 10, 24, 133) at the lo-cal end. In the method and system of the present invention, the near end test set (3, 60, 202, 300) is electrically transposed to the far end of the cable pair (2, 10, 24, 133) making it appear, for all in-tents and purposes, to be at the far end during the test while, in reality, physically remaining at the near end. The non-linear ele-ment (1), in its non-linear region, when suitably excited by two or more alternating signals of different frequencies (4, 12, 13, 41, 42, 113, 114), produces additional frequencies which travel back from the far end to the near end of the cable pair (2, 10, 24, 133) and are modified by the characteristics of the cable pair (2, 10, 24, 133). By selecting specific excitation frequencies and measur-ing the characteristics of the additional frequencies returned (6, 22, 52, 200), the characteristics of the cable pair (2, 10, 24, 133) can be deduced.

Abstract: In a switching system of multiple time slot interchangers associated with outlet ports, each interchanger includes multiple data memories respectively connected to inlet ports and connected to the outlet port with which the interchanger is associated. A set of commands is established for each incoming data signal. The command set includes an inlet port number (IPN), an incoming slot number (ISN), an outlet port number (OPN), and an outgoing slot number (OSN). During a write cycle, one of the inlet ports is selected in accordance with the IPN command and one of the data memories which are associated with the selected inlet port is selected in accordance with the OPN command. The selected data memory is caused to store the data signal of an incoming time slot identified by the stored ISN command into one of its storage locations identified by the stored ISN command. During a subsequent read cycle, one of the outlet ports is selected in accordance with the OPN command and one of the data memories which are associated with the selected outlet port is selected in accordance with the stored IPN command. The selected data memory is caused to read a data signal from one of its storage locations identified by the ISN command onto an outgoing time slot identified by the OSN command.

Filed: 1994-12-12
Granted: 2007-04-24
Abstract: The quantitative determination of various materials in highly scattering media such as living tissue may be determined in an external, photometric manner by the use of a plurality of light sources positioned at differing distances from a sensor. The light from said sources is amplitude modulated, and, in accordance with conventional frequency domain fluorometry or phosphorimetry techniques, the gain of the sensor is modulated at a frequency different from the frequency of the light modulation. Data may be acquired from each of the light sources at differing distances at a frequency which is the difference between the two frequencies described above. From these sets of data from each individual light source, curves may be constructed, and the slopes used to quantitatively determine the amount of certain materials present, for example oxyhemoglobin and deoxyhemoglobin in living tissue, or to determine at least the relative concentration of a material such as glucose.

Abstract: The problems associated with slow timing recovery in an ATM receiver are overcome by detecting the transmission rate of a received bit stream and periodically detecting the transmitted Enc_CR values, which are used to calculate additional estimated clock reference (Est_CR) values between the actual transmitted Enc_CR values. The Est_CR values are then used along with the actually received Enc_CR values to generate a phase locked loop (PLL) error signal (TC_ERROR), wherein the PLL is caused to converge more rapidly. In one embodiment, the TC_ERROR values are generated for each received cell or packet instead of only for each received Enc_CR value and, consequently, timing recovery is significantly speeded up. Additionally, the Est_CR values can be adjusted to minimize the effects of lost cells, as well as, drift in the transmission rate.

Abstract: Chemical cellulose pulp is made from sawdust utilizing a static down-flow retention vessel. By adding steam and cooking liquor to a flow of sawdust a heated slurry, at a cooking temperature of about 250-350°F, is produced. The heated slurry is, at superatmospheric pressure, moved downwardly in the static down-flow retention vessel while cooking temperature is maintained, for a time period of about 0.5-6 (preferably 1 to 3) hours, the slurry having a consistency of about 5-30%. At superatmospheric pressure, without significant reduction in pressure from the retention vessel, the slurry is cooled to well below cooking temperature by diffusing cooling liquid through it, as in a conventional pressure diffuser. The discharge from the retention vessel is preferably substantially solely gravity action (e.g. using a discharge with single convergence and side relief). Various mixing, diluting, thickening, steaming, and pumping devices are utilized in the system from initial steaming of the sawdust to passage into the top of the retention vessel.

Granted: 2006-12-12
Abstract: Method of removing iron from supersaturated sodium aluminate solutions resulting from alkaline attack by the Bayer method of treating alumina-monohydrate-containing bauxite. The method comprises the successive steps of grinding and optionally desilicating, in the presence of a decomposed liquor fraction, and then attacking at a temperature above 200 ~C, generally 240 - 270 ~C, said ground bauxite possibly desilicated by the remaining decomposed liquor fraction, in order to solubilize the aluminate hydrate and form after the attack a suspension of insoluble residue or red mud in the sodium aluminate supersaturated liquor. After cooling and dilution, said supersaturated liquor is decanted to separate the mud or insoluble residue from the supersaturated liquor, which after filtering is decomposed in the presence of a seed. The invention is characterized in that, after attack and during cooling of the suspension by the gradual reduction of pressure in the reactors, a small quantity of a calcium-containing compound is introduced into the suspension at a temperature exceeding 140 ~C.

Abstract: A tensioner mechanism adapted for placing tension in a drive belt of a mower deck, the tensioner including an elongate member operatively coupled with an idler arm, and slidably mounted with a support member operatively carried by the mower deck. A compression spring carried on the elongate member between the idler arm and the support member operatively presses the idler arm away from the support member and is completely compressed during normal mowing operations for generally blocking the idler arm from swinging toward the support member during operation. A threaded member within which said elongate member is slidably received is adjustably fixed with the support member by a pair of nuts that can be adjusted on the threaded member to alter the position of the threaded member with respect to the mower deck for adjusting the tension that the idler pulley places in the belt during normal mowing operations. The position of an indicator adjacent to the threaded member serves to visually indicate to the operator that the tensioning mechanism has been properly adjusted to place the appropriate amount of tension in the belt.
