Patent NL-7509414-A (NL)
Title: Nitrogen oxide reduction - using steam hydrocarbon injection
IPC: B01D53/54
Filed: 1975-08-07
Abstract: NOx gases are reduced by (a) burning fuel and stoichiometric air (support gas) in a first refractory chamber (b) introducing NOx gases (c) introducing mixt. of hydrocarbon gas and steam to form reducing atmos. (d) passing gas effluent at 2000 degrees F to a second refractory chamber (e) rapidly cooling the effluent to 1250 degrees-2000 degrees F and (f) adding air to second chamber to burn excess combustibles. Pref. gases such as H2, Co and/or CH4 may be supplied direct to provide the reducing atmos. Since reducing atmos. is not provided by burner operation, close control of fuel burning is not required.

Title: Directionally sensitive clinometer with coil halves - which are around sphere and have separating internal air gap each with surface facing curved area
IPC: G01C9/06
Filed: 1977-03-31
Abstract: The directionally sensitive clinometer is used to determine the position relative to the vertical of an element connected to it. It consists of a housing with a cavity curved at the bottom and containing a movable sphere. The sphere can affect a magnetic flux in a coil excited by a current and located in the cavity. The end surface of the coil faces the sphere. The two halves (7) of the coil (1) are separated by an internal air gap. The end surface of each half faces the curve. The halves can be separated vertically or horizontally. There is a slotted guide in the direction of the coil halves. The system can be refined by using a second pair of coil halves at right angles to the first pair.

Title: Method for removal of monovalent ions from znso4 electrolyte by electrodialysis
Inventor: BALL DONALD L
IPC: C01G9/06
Filed: 1987-04-21
Abstract: Monovalent ions, especially chloride, fluoride and thallium, are efficiently removed from ZnSO4 electrolyte by electrodialysis using alternating monovalent anion permselective membranes and cation exchange membranes or monovalent cation permselective membranes. Electrodialysis is carried out under turbulent flow conditions, at up to 60 DEG C, a differential membrane pressure of less than 150 kPa, a current density of 10 to 500 A/m<2>, and a pH of less than 5.5. Where both chloride and fluoride are removed a pH of 3.5 to 5.5 is maintained. Deposition of manganese and zinc on the electrodes is minimized by at least one of a number of means including arranging the membranes such that the end membranes are monovalent anion permselective; selecting a large electrode rinse flow; adding a small amount of soluble antimony and/or cobalt to the rinse flow; and using a cathode made of a material that promotes hydrogen evolution over zinc deposition. The electrode compartments are preferably rinsed with a 0.1 to 1.0 M Na2SO4 solution at pH 0 to 4.

Patent PT-96481-A (PT)
Inventor: DENT PAUL WILKINSON
IPC: H03L7/107
Filed: 1991-01-15
Abstract: The present invention relates to frequency synthesis with a controlled oscillator (20) included in a phase locked loop, where the frequency of the oscillator output signal is divided (22) periodically by different integers, such that the frequency is, on average, divided by a value which is equal to an integer N plus or minus a numeric fraction whose absolute value is smaller than one. The phase position of pulses formed in this way is compared with the phase position of pulses which derive from a reference signal (10, 12), therewith forming a phase error signal. For the purpose of suppressing periodic variations of an oscillator control signal as a result of phase jitter, there is added or subtracted to the phase error signal, in a known manner, a correction value (24, 26) which is dependent on the aforementioned numeric fraction. In order to eliminate the need to multiply the correction value by a factor which is proportional to the inverted value of the integer N, the phase error signal is instead amplified with a factor N (28) prior to adding or subtracting the correction value. The loop bandwidth is also held constant in this way. <IMAGE>
