Inventor: VOLDEN DOUGLAS J
IPC: F16J15/40

Abstract: This invention relates to barrier seal systems (10) for sealing the annular space between a housing (14) and a rotating shaft (12) which extends through a bore (16) in the housing (14). The seal system (10) has inboard (66) and outboard (46) mechanical end face seals. The inboard seal (66) faces have spiral grooves (98) for pumping a buffer fluid from a buffer chamber (68) between the two seals (46-66) toward the high pressure side of the inboard seal (66). The primary ring (76) of the inboard seal (66) may be double balanced. For high pressure applications, the buffer fluid may be pressurized and a pumping ring may be included in the outboard seal to circulate buffer fluid. High pressure applications also require two hard seal rings and optimum dam (100) and face widths. Buffer fluid can be supplied to the seal system by a reservoir (30) connected by a gravity feed line (108-112). A buffer fluid containment device may be attached to the high pressure side of the seal (10) to prevent process fluid from contaminating the seal faces or secondary seals.

Abstract: For the separation of particular ions or groups of ions to the greatest possible extent from solutions without the use of chemicals, a device known per se is used which consists of at least one chamber which is charged with the solution and filled with ion exchanger and which is separated on opposite sides by an anion exchanger membrane and a cation exchanger membrane from chambers carrying the flow of washing solution, an electrical potential gradient existing between the chambers, with the proviso that the ion exchanger used is an ion exchanger which is selective for the ion or group of ions. Admittedly, this does not lead to a pure separation of only this particular ion or of the group, certainly not in one step. Under some circumstances, a reduction, not otherwise necessary, also of the other dissolved materials must be accepted. However, the relative quantities lead to a decisive advantage which frequently will make the use of the process worthwhile. The particular ion or the group is, as is found, extracted from the first-mentioned chamber by the electrodialysis to a significantly greater extent than the other ions.

Abstract: In a telemetry method for measuring the duration of a period, an increased measurement resolution is achieved by the fact that firstly clock pulses are counted over the duration of one period of the signal to be measured for determining an approximate duration of the period, that then a table containing this period duration count is read out in order to obtain a number of measurement periods which is allocated to a period duration range, the number of measurement periods being selected in such a manner that counting of the clock pulses by means of the counter does not quite lead to a counter overflow even with the longest duration of a period in this range of period durations, and that then clock pulses are counted over the number of period durations of periods of the measurement signal so that finally the count obtained, together with a coding of the number of measurement periods, can be transmitted to a telemetry receiver. <IMAGE>

Abstract: In collectively and electrically erase a plurality of memory cells, to set the threshold values of the memory cells constant, electrons are previously stored in the floating gates of the memory cells (M₁₁-M lm ) (S1). The memory cells whose floating gates are accumulated with electrons are electrically erased and the threshold value of each erased memory cell is checked. The collective erasing of the memory cells is repeated until the threshold values of all the memory cells become equal to or below a first value (V EV ) (S2-S9). When it is detected that the threshold values of the memory cells become equal to or below the first value (V EV ), it is discriminated if those threshold values are equal to or above a second value (V TN (E) min ) smaller than the first value (S10-S15). When there is a memory cell whose threshold value is equal to or below a minimum value (V TN (E) min ) allowable on the design base in the previous discrimination step, that memory cell is over-erased and the memory chip containing the memory cell is determined as a defect (S12).
