Patent EP-0078907-A2 (EP)
Inventor: BERKENKAMP GARY DEAN
IPC: E21B47/18
Filed: 1982-09-23
Abstract: An apparatus for removing pulsation noise caused by a well drilling fluid circulating pump from fluid pressure pulse transmitted measurement while drilling data passing through drilling fluid in a drill string of a borehole measurement while drilling system. The noise filtering apparatus includes a drilling fluid pressure sensor and an adaptive estimator that memorizes the pulse noise signature of a pump in synchronization with the pump's strokes. The memorized signature is removed from the signal data derived from pressure pulsations in the drilling fluid in order to remove or filter the pump's noise or pressure signal disturbing influence from this data. The adaptive estimator is arranged such that it will compensate for changing operating conditions of the pump so that this pump created noise is substantially, continuously filtered from the measurement while drilling data.

Abstract: Apparatus is disclosed for detecting the passage of double or overlapping banknotes, or for detecting banknotes with corner folds or on which there is adhesive tape. Banknotes are fed serially into the nip of a pair of rotating rollers (R1, R2). A follower roller (R2) is displaced vertically from a datum roller (R1) by the passage of the banknote. The thickness of the banknote is gauged by a pair of proximity sensors (S1, S2) over each end of the follower roller. 
     A feature of the apparatus is the provision of a land (5) at each end of the datum roller (R1). This ensures that the banknote-engaging surfaces of the rollers maintain their separation when no banknote is passing through the nip, so as to prevent any dirt being ironed fiat onto the rollers. 
     In an alternative embodiment, both surfaces of the rollers are flat, and the separation of the rollers is maintained by controlling the position of the follower roller axis, the follower roller axle being supported at each end by brackets which are pivoted about a further axis.

Abstract: An eye shield or eyepiece for a viewing device, especially for a day and night vision sighting device for aiming a weapon essentially comprises a headrest and first and second mounting frames. These components form an assembly for mounting on the housing of a viewing device. For the practical manipulation and adaptation of the headrest to the form of the head of the observer, two hinge-like articulations are provided in mutually spaced relationship on the external face of a forehead rest of the headrest. A relatively low pressure force against the inner face of the forehead rest deforms and correspondingly adapts the elastomeric or flexible plastic headrest. In order to actuate, for instance, a laser distance measuring device mounted in the viewing device, the assembly formed by the headrest and first and second mounting frame components is articulated to the housing of the viewing device, and an actuating or switching member mounted on the second mounting frame can be brought into engagement with an enabling switch.

Abstract: The apparatus ensures that the pressure of the synthetic resin components, in particular polyurethane-forming components, is kept constant. This is achieved by a device which generates or makes available a constant force, which is then used for the purpose of keeping the pressure constant in each component line. This compensates for pressure fluctuations, which can occur, in particular during mixing, when valves are opened and closed. For example, considerable pressure fluctuations can occur if mixing is carried out in a mixing chamber which is equipped with a pull-back ram of the same diameter, which passes over the inlet openings of the mixing chamber and, if appropriate, is also equipped with return channels for each component. These pressure fluctuations are prevented by action being brought to bear for example on the valve bodies of the injection nozzles or injection valves in such a way that the pressure on entry into the mixing chamber is always constant. Even in the return before each mixing operation, a constant pressure is ensured in the component lines.

IPC: F22B37/56
Filed: 1984-07-13
Abstract: A method of identifying a parameter of a model for a rate of loss of boiler efficiency due to a soot-blowing operation, in a boiler or other convection heat transfer device having a plurality of heat traps, comprising measuring a time since a last sootblowing operation in the heat trap in question, measuring an overall boiler efficiency at the beginning of soot-blowing for the heat trap in question, measuring a change in efficiency due to the sootblowing operation and calculating the parameter using an equation. According to the equation, the ratio of efficiency change over overall boiler efficiency equals the time factor since the last sootblowing operation times the parameter minus a summation of factors for each of the other heattraps and their associated sootblowing operations. A method is also disclosed for enhancing a sootblowing operation wherein, with a plurality of heat traps, sootblowing is performed in an upstream heat trap in prefer- ance to a downstream heat trap, when both heat traps are near a fouled condition which would require sootblowing. This prevents premature fouling of a downstream heat trap which has recently been cleaned by soot blown off an upstream heat trap.

Abstract: A vibratory temperature transducer includes a pair of elongate, generally parallel bars coupled together at one end in a type of tuning fork arrangement. The bars each have a thickness of t, a width of w and a length between free and fixed ends of L. The distance between the free end and the point where the bars are coupled together is m. Apparatus is provided to cause the bars to vibrate in torsional opposition, where the frequency of vibration is generally a function of temperature. Apparatus is also provided for determining the frequency of vibration of the bars so that when the bars are subjected to a change in temperature, the temperature can be readily determined by simply determining the magnitude of the frequency change. By careful determination of the dimensions L, m, t and w, spurious modes of oscillation of the transducer, which cause a reduction in the mechanical Q and thus an erroneous reading of temperature, are avoided.

Abstract: @ in a relational database management system, interactive error-handling means comprises means for calling an operation means and a fetch means. The fetch means operates against a cursor to retrieve a record occurrence noninterac- tively for operation. The operation means validates the selected operation and can set an error condition signal. When the selected operation is valid, the operation is performed and the operation means provides a return signal to the calling means, which calls the fetch means to retrieve the next record occurrence. When the selected operation is invalid, the fetch means responds to the error condition signal by operating interactively to display the previously retrieved signal with an error message. The interactive user can correct the error so that noninteractive operation can continue.

Abstract: In an improved method for thermally growing an oxide layer on a silicon surface of a semiconductor body a first oxide layer portion is grown over the silicon surface in a first thermal oxidation process at a temperature of less than about 1000°C. The semiconductor device is then annealed in a nonoxidizing ambient at a temperature above about 1000°C, and finally a second oxide layer portion is then grown over the first oxide layer portion in a second thermal oxidation process to complete the growth of the oxide layer. The silicon surface may be of either polycrystalline or monocrystalline material. This method avoids both the dopant outdiffusion problems associated with present High-temperature oxidation processes and the stress-related irregularities associated with known low-temperature oxidation processes.
