Abstract: An improved internal combustion engine unit which includes a separating aperture between the cylinder and a separation chamber, and a separating valve adapted to control closing and opening the separating aperture. The separation chamber is connectable to the intake manifold and to the exhaust manifold, respectively, by the intake and exhaust apertures. Opening both the separating valve and the exhaust valve enables gas flow from the cylinder volume to the exhaust manifold through the open separating aperture, the separation chamber and the open exhaust aperture. Opening both the separating valve and the intake valve enables gas flow from the intake manifold to the cylinder volume through the open intake aperture, the separation chamber and the separating aperture. The intake valve and the exhaust valve are driv-en by solenoids controlled in turn by an engine computer.  The separating valve is driven by a camshaft driven in turn by the engine.

Abstract: An optical, non-contact sensor for measuring the thickness or weight of layered products and particularly those that contain a light-reflective substrate incorporates a reflective surface to cause incident radiation from a light source to plurality of time within the layered products before being detected in a receiver. A diffusing element can be incorporated as a diffuse source of illumination. The Lambertian-type light scattering generated by the diffuse element causes the incident light to interact multiple times with the layered product resulting in enhanced sensor sensitivity to selected components in the layered product and measurement error induced by specular reflection of the light from the reflective substrate is minimized.

Title: Detector system of slickline irregularities
Inventor: GONZALEZ CANCINO ALBERTO
IPC: E21B47/00
Filed: 2013-06-20
Abstract: Detector of Slickline Irregularities (DILA) is a comprehensive electronic system to proactively detect and assess irregularities presented by slickline due to interventions in the field (production wells) or to a new slickline. It is governed by the principle of eddy currents or eddies or Foucault currents. This comprehensive electronic system allows to detect and assess irregularities of slickline used in interventions in oil wells. It is noteworthy to mention that these lines can vary in diameter depending on the operation to be performed on each well. It comprises: optical encoder, eddy current sensor, eddy current reader, an electronic module for data acquisition and a personal computer. DILA allows to obtain an electronic record by monitoring of the integrity of the slickline used in well service operations, allows interpretation of the data for graphing and keeping records for later use, providing reliability and security to the scanned line. It helps to reduce failures in the slickline as a result of rupture due to deformations for excessive stresses or collisions, which are created within the producing wells, it detects flattening and bending, lack of nickel coating (darkest areas on slickline) porosity and corrosion probably due to acid attack on line during downhole operations.

Abstract: Peak fade depth is measured (202) over a period of time, and a bandwidth of a channel filter (104) is then determined (206) according to the measured peak fade depth (202). In preferred embodiments the average peak fade depth over two or more time slots is used. In a specific embodiment, an a filter (206) is used to determine the bandwidth of the matched filter (104), in which a is determined based upon the measured peak fade depth (204). In various embodiments, peak fade depth is correlated to the Doppler shifting of the channel, which in turn is used to determine the bandwidth of the matched filter by way of the a parameter. Hence, a non-linear equation can be used to determine the value of a which yields a minimum bit error rate for the matched filter (104). More specifically, a matched filter (104) is matched to a received signal r(t) having k states according to a plurality of matched filters M k and outputs a signal given by |r(t)-C k (t)*M k (t)|2, in which C k (t) is a channel estimate provide by a channel tracker (106) for a state k at time period t that is given by C k (t) = a*c k (t) + (1-a)*C k (t-1), c k (t) = M k *r(t)/(M k *conj(M k )), and conj(M k ) is the complex conjugate of M k . For each time slot, a is computed from the running average of the peak fade depth (202) according to a predetermined equation (204).
