Title: Method for producing network-like metal mats and apparatus for carrying out the method
Inventor: STAHL KARL-HERMANN
IPC: B21D31/04
Filed: 2011-07-20
Abstract: The method serves for producing network-like metal mats from metallic strip material, for which purpose the strip material is first provided with notches (2), running parallel to one another, for the forming of metal wires (1), by means of notching rollers. The notches (2) are thereby formed to such depths, depending on the material, that as far as possible no sliding fractures are formed. The notches (2) are interrupted by un notched regions a the mutual spacing of which in the respective notch (2) determines the later possible mesh width at least in such a way that they later form network nodes (4). The network nodes (4) are offset by approximately half a network node spacing in the respectively adjacent notches (2). Then, the strip, formed in this manner, is subjected to a flexing process, in which the webs (3) adjoining the base of the notch and still connecting the metal wires (1) to one another undergo multiple bending deformation about the longitudinal axis thereof in such a way that incipient cracks occur as a result of fatigue fracture. This leads to the complete separation of the metal wires (1) in the region of the webs (3), while no incipient cracks form at the network nodes (4). Finally, the strip material is subjected to transverse tensile forces acting on both its peripheral metal wires (1), whereby a widening deformation of the wire strip (5) into a network-like structure takes place. The invention also relates to an apparatus for carrying out the method and to a metal mat produced by said method. Figure 1

Title: Zero liquid discharge palm oil clarification process
Inventor: KANDIAH SIVASOTHY
IPC: A23D7/02
Filed: 2014-09-10
Abstract: A multi-step process for extracting palm oil (528) from a feed liquor (500) consisting of a mixture of oil, free water, bound water, suspended solids (includes fine and coarse fibrous solids and sand), dissolved solids and gums from prior processing steps in the palm oil extraction process, while achieving environmental compliance and reducing the carbon and water footprints. There is no highly polluting liquid effluent produced as a by-product that must be treated prior to discharge. In the new process, most (but not all) of the free water in the feed liquor is removed by evaporation (519), using oil in the feed to the evaporator as a fluidizing medium, to convert the effluent discharged from the clarification process from a liquid form to more easily disposable solid form (514). Removing most of the free water breaks oil/water emulsions and leads to the gums becoming insoluble and forming a gel-like substance that readily precipitates from the oil. Removal of the gums from the evaporated liquor is achieved by a decanting centrifuge (513), using suspended solids in the feed to the decanter as a carrier for conveying the gums out of the decanting centrifuge. Various clarification plant configurations incorporating the above mentioned steps are possible using either two-phase or three--phase decanting centrifuges. In the simplest clarification plant configuration, the evaporation step precedes the decanting step and the suspended solids required for the removal of precipitated gums by the decanting centrifuge are present in the feed to the evaporator. To minimize the likelihood of evaporator fouling, it is advantageous if the decanting step (513) precedes the evaporation step (519), and the evaporated liquor (521) is either recycled completely, or recycled after separating most of the oil by using a settling tank (526), and mixed with the feed liquor (500) to facilitate removal of gums by the decanting centrifuge (513).

Title: Electromechanic stretcher
Inventor: HINKOV DIMITER H
IPC: B23B31/28
Filed: 1981-01-23
Abstract: A device for applying a force, such as a clamping device, comprises an electric motor (2) which, when energised, causes rotation of a nut (8) which in turn causes linear displacement of a spigot (9) and of an output element (16). When the output element (16) meets a resistance and is arrested, a resilient assembly (15) is compressed, and relative movement takes place between a rod (17) carried by the output element (16), and a tube (18), carried by the spigot (9). This relative movement is detected by a transducer (20) which, when the movement reaches a predetermined value, delivers a signal which causes the motor (2) to be de-energised. The device enables a predetermined clamping force to be achieved and maintained substantially constant, or varied in a predetermined manner. The device may be used on machine tools. <IMAGE>
