Abstract: ABSTRACT OF THE DISCLOSURE      A method for identifying anomalous noise amplitudes in seismic records by deriving a measured amplitude factor over   predetermined periods of time  or time windows for a predetermined number of traces comprising the records is disclosed.  A noise-free amplitude factor for the same periods of time and number of traces is also computed using a Gauss-Siedel method of matrix inversion. A ratio of the measured and noise-free amplitude factors is  made  to  determine  a  correction  factor which  is compared  to  a  used  defined  threshold  value  for determining a presence of anomalous noise amplitudes in the seismic records.   Based on the comparison of the correction  factor to  the  threshold value,  the user determines  whether  to  suppress  or  correct  traces experiencing the anomalous noise amplitudes.

Abstract: "PROTECTIVE COVERING FOR A    MECHANICAL LINKAGE"           Abstract of the Disclosure A covering for a mechanical linkage comprises a material which is substantially impermeable to both liquid and particle contaminants and conforms to the outer surface of the mechanical linkage. Because the covering conforms to the surface of the mechanical linkage, the covering does not have loose portions that billow and rub together as the mechanical linkage operates. This lessens the possibility of pieces of the covering and contaminating material detaching and falling from the mechanical linkage. The covering also comprises access openings whereby the mechanical linkage can be served without removing the entire covering. In a preferred embodiment, the covering comprises a plurality of sections, each section having fasteners for securing the sections about the mechanical linkage. The separate seconds can be individually removed and replaced in a relatively short period of time. In a more preferred embodiment, the covers comprise a non-woven polymeric fabric which is a barrier to industrial coatings and finishes such as paint. The non-woven fabric comprises a central layer of melt-blown polymeric fibers placed between and bonded to two layers of spunbonded polymeric fibers. The outer layer of spunbonded polymeric fibers is preferably calendered to prevent  and bonded to resist abrasion. The outer layer of the cover comprises a fluorocarbon as a barrier to industrial coatings and finishes and an inorganic salt to prevent static electricity buildup on the outer layer. In addition, the polymeric fibers of the outer layer preferably have a non-white color which is distinctive from the color of the polymeric fibers of the inner layer so that the outer layer is distinguishable from the inner layer and any fibers from the outer layer that might detach from the covering during operation of the mechanical linkage are identifiable. The covers are particularly suited for protecting spraypainting robots from incident paint or varnish spray.

Abstract: 814,093. Automatic control systems. FAIREY AVIATION CO. Ltd. Feb. 12, 1957 [Feb. 14, 1956], No. 4662/56. Class 38 (4). In a servo control system having a feedback loop, means responsive to increased gain round the loop at a frequency outside the range of working frequencies reduces the gain of an element in the feedback loop. In Fig. 3 an aircraft radio receiver (not shown) produces an electrical signal, representative of displacement of the aircraft from a radio beam or a turn control signal from a remote radio operator, which is applied at 10 through a low-pass filter 11 and an adding unit 13 to an amplifier 17 energizing an electrically operated valve 19 controlling a fluid-actuated rudder 22 of the aircraft 24. The consequent lateral acceleration of the aircraft is made proportional to the control signal by an electrical signal derived from an accelerometer 30 which is applied through an amplifier 34 to an adding unit 13. A signal is also applied to adding unit 13 from an oscillator 81 having a frequency close to the self-oscillation frequency of the feedback loop. After passing through amplifier 34 this signal is separated from the feedback signal by a band-pass filter 83, rectified, and compared with the rectified output of oscillator 81 in a circuit 94. Circuit 94 is arranged so that if the gain of the feedback loop exceeds, say, 0.7 the consequent output from circuit 94, after smoothing at 95, reduces the gain of feedback amplifier 34. An alternative arrangement in which the gain of the forward part of the feedback loop is controlled, is referred to. A control signal limiter may be associated with the input to adding unit 13. In a modification oscillator 81 is dispensed with and self-oscillation is arranged to limit itself by controlling the gain of the feedback amplifier. Amplifier 34 may alternatively be controlled by a signal which is an integral function of oscillation amplitude. Suitable forms of filter and feedback valve amplifier are described and component values given.

Abstract: Symmetrical electrical snubber circuit for protecting at least two series-connected switch members (S1; S2) against excessive voltage and current increase during switching. The voltage increase over each of said switch members is limited by a series circuit of a capacitor and an element having diode action (D1, C1; D2, D2) connected in parallel with said switch members. The magnitude of the DC supply voltage is effectively limited by a further series circuit of a capactior and an element having diode action (D3, C3; D4, C4) connected with said switch members. A freewheeling diode (D5, D6) is connected in parallel with each of said switch members. By incorporating a coil (L1, L2) in the supply lines to the switch members, the current increase during switching-on of a switch member is limited. Like this, a symmetrical snubber circuit which is as low in stray inductance as possible is obtained. The energy stored in the coils (L1, L2) as well as the energy stored in the capacitors (C1; C2) being transferred to the further capacitors (C3; C4) due to resonant action. The energy in these further capacitors can then be discharged with the aid of energy transport means (ET). The snubber circuit according to the invention is in essence loss-free.
