Abstract: A process for dewatering sewage sludges, the dewatering characteristics of which have been improved by adding an organic flocculant, on a chamber filter press, wherein the greater part of the water in the flocculated sludges is removed by gravity filtration in a process step upstream of the chamber filter press, without application of a pressure difference, and the actual pressure filtration, on the chamber filter press, is only then carried out. In principle, commercial products can be used as the organic flocculant. These are water-soluble, macromolecular compounds which have been obtained by polymerization or copolymerization of acrylamide, acrylic cid and/or their salts, or of esters of acrylic acid or methacrylic acid with specifically modified alcohol components.

Abstract: A device useful for detection of air/fuel ratio of an air- fuel mixture subjected to combustion in a combustor by sensing oxygen in the exhaust gas, using a solid electrolyte concentration cell type oxygen-sensitive element (10) which requires supply of a DC current (l s ) to flow through its solid electrolyte layer (18) between reference and measurement electrode layers (16, 20) to establish a reference oxygen partial pressure at the interface between the reference electrode (16) and the solid electrolyte (18). The device comprises a control circuit (26) to vary the intensity of the current (I S ) for the oxygen-sensitive element (10) in dependence on the magnitude of output voltage (V s ) of the oxygen-sensitive element (10) at least when predetermined one of said output voltage (V s ) and a reference voltage (V o ) is higher than the other in order to compensate variations of the magnitude of the reference oxygen partial pressure caused mainly by variations of the temperature.

Abstract: Disclosed is a process for the transmission of information over television networks wherein certain information is encoded in digital form and transmitted by supplementing and/or replacing the information forming the conventional program. The digital information is received by a conventional receiving set equipped with a decoding, memory and detector means. Information is transmitted in the form of analog signals subdivided into scans or groups of scans, each scan having associated identifying material. The information transmitted in digital form has other identifying material and is transmitted generally synchronously with the corresponding information in analog form. The transmissions are received by receivers with detectors sensitive to the identifying material and which have analog-digital and inverse conversion means as well as memory and decoding means to reproduce the information contained in the analog and digital signals.

Abstract: In a railway track ballast tamping device, a tamping unit is carried for vertical adjustment by a support mounted on the frame structure of a vehicle and comprises at least one pair of jointly-operating tamping tools crossing each other. The arm of these tools are adapted to pivot on opposite eccentric cranks formed on an eccentric shaft rotatably mounted in a bearing rigidly fastened to the support; the upper ends of the arms, opposite the pick-forming thereof, are each pivotally connected to a hydraulic cylinder inclined not in excess of 30 DEG  to the vertical; the planes passing through the axis of rotation on the eccentric shaft and the center of the opposite eccentric cranks thereof form between them an angle of 40 DEG  to 80 DEG  in order to warrant a symmetrical, synchronous oscillatory motion of the packers carried by the lower ends of the picks. To prevent the transmission of detrimental vibration to the support during the rotation of the eccentric shaft, there are provided, in addition to out-of-balance weight carried by a flywheel rigid with the eccentric shaft, balance weights fastened to the hydraulic cylinders and disposed above the level of the pivotal connections between these cylinders and the support. Furthermore, the tamping tools of a pair disposed on the same side of a tie have their upper ends rigidly interconnected.

Title: Gearbox comprising a resiliently mounted pinion
Inventor: CHARLES CHRISTOPHER JOHN
IPC: F16H57/02
Filed: 1981-06-17
Abstract: A marine gearbox designed to suppress the transmission of gear-tooth generated vibration to the support structure. A pinion (3) is mounted in a pinion housing (1), which includes a pinion bearing (15), which in turn is resiliently mounted from a gearwheel housing (4) and supporting structure. Inter-tooth vibration is largely absorbed by the pinion structure rather than transmitted through the relatively massive gearwheel (2) and gearwheel housing (4) to the support structure by providing the resilient mounting with such a stiffness that the characteristic natural frequency of the pinion assembly lies between one third and one half of the lowest tooth contact passing frequency.

Abstract: An automated system for examining a workpiece 6 treated so that flaws are revealed by concentrations of indicator on its surface scans the workpiece surface to provide an output signal representative of the luminance of surface regions. These are stored in a memory 12 and first and second signals representative of the average luminance of a number of regions A, B, C, and E, F, G on opposite sides of a central region D are formed. The first and second average signals are compared to determine which one represents the greatest concentration of indicator and the selected signal is used to derive a threshold value which is compared with the output signal representative of the luminance of the central region D. A flaw is indicated when the central region luminance signal is greater than the threshold value. Using this variable threshold technique based on the highest average of the surroundings it is possible to achieve great selectivity in the examination of the workpiece which takes into account differences in the background levels of indicator and enables automatic scanning of a workpiece which is as or more sensitive than the human eye.

Abstract: An improved method of making a carbon composite product wherein a fabric comprised of oxidized or otherwise stabilized polyacrylonitrile fibers is heat treated and then coated with a closely controlled amount of a carbonaceous binder such as a polyimide resin. The fabric is then further heat treated to thermally fuse the resin to the fabric to form a rigid, easily handleable material The carbonaceous binder is applied to the fabric in a manner whereby substantial encapsulation of the individual fibers is avoided. Next the material is cut into swatches of a predetermined size and shape and the segments are arranged into a basic or starting substrate having a volume greater than the desired volume of the end product. The basic substrate thus formed is then subjected to controlled temperatures and pressures to form a shaped substrate having a known fiber volume, a high degree of open porosity and a shape substantially corresponding to the shape desired of the end product. During this step, the fiber volume of the substrate is adjusted and the segments are fused together to temporarily hold them in position within the substrate. The shaped substrate thus formed is then pyrolyzed to form a carbon fibrous substrate which is densified in a freestanding configuration by the deposition of pyrolytic carbon interstitially thereof to form the desired end product. Because the portions of the fibers which are not encapsulated with binder are free to move, stresses generated in the substrate during pyrolyzation due to material shrinkage and the like are effectively distributed.
