Title: Digital pressure derivative method and program storage device
Inventor: VENERUSO ANTHONY
IPC: G01V1/36
Filed: 2003-12-20
Abstract: In a Digital Pressure Derivative Technique (DPDT) which uses convolution, an input signal including noise is convolved with a wavelet to produce an output signal which is a derivative of the input signal and which is substantially devoid of the noise. The DPDT can be used in many applications; however, in one such application, a pressure signal from a wellbore including noise is convolved with a special wavelet to produce an output signal which is the derivative of the input pressure signal, the output signal being substantially devoid of the noise. The wavelet is made from the unit sample response of a bandlimited, optimum linear phase Finite Impulse Response digital differentiator. The DPDT technique enables analysts to customize the differentiation based on the quality of the measured data without having to use traditional, subjective smoothing algorithms. The results presented here, in connection with the one such application mentioned above, bring significant improvements to the diagnosis and interpretation of pressure transient data, and interpretation techniques that utilize higher-order derivatives are now practical.

Title: Net cover for bulk cargo
Inventor: VISHNIVETSKIY IVAN YAKOVLEVICH
IPC: B61D39/00
Filed: 2013-02-08
Abstract: The invention is related to means for covering solid loose hazardous goods (HG) when transported by vehicles. The proposed covers (tents) are made of hardly combustible nets (HCN) with 1.5-45 mm mesh size joined together by means of seams and non-combustible fabrics and having eyelet holes and loops over the periphery for fastening the tent to the vehicle walls. HCN covers can be used for HG protection against adverse external factors during transportation in open vehicles, e.g., in open railway gondola cars (GC). According to the first method, the HCN cover is used for HG protection against ignition and fire of the hazardosu goods because of an accidental fall of open flame sources - burning cigarettes, sparks from exhaust pipe of a diesel locomotive - on the HG surface. The cover proposed for protection of lump and pelletized sulphur is made, e.g., of glass-fibre fabric net having a mesh size of 1.5 to 5 mm. Said net permits protection of sulphur surface against ignition and fire in case of a contact with a fire-hazardous spark of 5 mm in diameter at a temperature 600°C able to set fire to sulphur. Another method of using the HCN cover is proposed for protection of HG, e.g., coal, against dissipation by wind and scattering from GC during train moving on route at a speed of up to 80 km/h. Under action of aerodynamic forces, lumps of cargo tend to roll over the cargo surface and tear off from the main mass of the cargo to be carried by air flow beyond the GC perimeter. Rolling and tear-off of lumps of cargo is prevented by the net cover pressed to the cargo surface with plurality of transverse-diagonal tapes.
