Abstract: The invention concerns an apparatus comprising a body (2) wherein a piston (6) is mounted sliding alternately driven by an incompressible fluid under pressure, said body containing part of a tool (4) which is guided in translation in a wear sleeve (3), the end of the tool located inside the body being subjected to the repeated impacts of the piston (6), while the other end projects beyond the body and is designed to be supported on the rock or analogue to be destroyed, the tool being retained in the body by at least a transverse key (13). One of the keys (13) retaining the tool passes through aligned holes provided in the body (2), into the wear sleeve (3), and overlaps inside the inner cylindrical space of the sleeve, the tool (4) having a transverse groove (12) for the key (13) to pass through.

Title: Systems and methods for providing controllable texture sampling.
Inventor: BOYD CHARLES N
IPC: G06T5/00
Filed: 2003-04-10
Abstract: Systems and methods are provided for controlling texture sampling in connection with computer graphics in a computer system. In various embodiments, improved mechanisms for controlling texture sampling are provided that enable 3-D accelerator hardware to greatly increase the level of realism in rendering, including improved mechanisms for (1) motion blur; (2) generating anisotropic surface reflections (3) generating surface self-shadowing (4) ray-cast volumetric sampling (4) self-shadowed volumetric rendering and (5) self-shadowed volumetric ray-casting. In supplementing existing texture sampling techniques, parameters for texture sampling may be replaced and/or modified. <IMAGE>

Title: Multi-layer adjuvants for controlled delivery of agro-materials into plant tissues
Inventor: ZEEV WIESMAN
IPC: C05G/
Filed: 2004-03-31
Abstract: Composition for the treatment of plants, that is a structural combination of agro-materials and adjuvant formulations. A specific composition is a particulate material in which the agro-material particle constitutes the nucleus of each composition particle and adjuvant formulations constitute a coating of the composition particle. The adjuvant formulations comprise a plurality of components, which constitute substantially superimposed coating layers in each particle of the composition and preferably comprise a combination of lipophilic and hydrophilic cuticle surface active agents, wetting agents, thickening agents and fatty self-emulsified components. Special compositions are those in which different agro-materials are used. The agromaterials are chosen from fertilizers, trace elements, plant growth regulators, biostimulants, pesticides, herbicides and insecticides. The invention also relates to methods of treating plants by applying the agro-material compositions, and to methods of preparing the agro-material compositions.
Patent ZA-200403139-B (ZA)
Title: Determining electrical faults on underground power systems using directional element.
Inventor: ROBERTS JEFFREY B
IPC: H02H3/40
Filed: 2004-04-23
Abstract: The directional element, following enablement under selected input current conditions, calculates a zero sequence impedance, in response to values of zero sequence voltage and zero sequence current. The current value is selected between two possible values, one being the value from an associated current transformer, the other being the sum of the currents IA+IB+IC. The calculated zero sequence impedance is then compared against sensitive selected threshold values, established particularly for ungrounded systems. A forward fault indication is provided when the calculated zero sequence impedance is above a first established sensitive threshold value, and a reverse fault indication is provided when the calculated zero sequence impedance is below a second established sensitive threshold value.
