Abstract: The present invention concerns a method for fixing a knife in wood chipper apparatuses over the whole knife length between two steady surfaces. The fixing force is developed by means of a roller chain located between two counter surfaces and reversing its direction at each of its couplings, the roller chain having stationary end rollers and intermediate rollers at the couplings, the intermediate rollers rolling during the press movement in the longitudinal direction of the chain. An external force is applied to the roller chain, the force changing its direction at the touching points of the rollers, so that the force applied to the roller chain affects to multiple points of the counter surfaces thus forming a prominent total pressing force.

Abstract: An intragastric catheter provides satiety due to its presence in the stomach cavity. Tactile sensation by a plurality of fingers that extend from the device provides satiety. Normal peristaltic action upon the device provides movement of the fingers relative to the stomach wall, reducing the likelihood of ulceration or necrosis. The structure of the intragastric catheter reduces the level of precision required in placement of the device, and the likelihood of blockage of conduits to and from the stomach by the device is reduced.

Abstract: There is at present a saliva ejector commonly in use whose tip is designed in such a way as to allow suction and injury to tissues of the floor of the mouth.  This occurs because of slits cut in to the tip, which allow for saliva to be sucked in.  The length of the slits, however, facilitates the aspiration of tissues of the anterior portion of the mouth where the saliva ejector is most commonly placed. This occurs almost regularly in older patients where the tissue becomes flaccid with age. An improvement to the design would tie as follows: the tip of the saliva ejector should be perforated with holes of 1mm diameter arrayed in the following pattern: 6 circumferentially on the end and 2 mm from the edge, and 2 rows of six holes each around the perimeter. The two rings lie 3mm and mm from the end of the ejector tip.

Abstract: Certain novel formulations of turf additives that act in such a manner as to permit proper amounts of moisture to contact root systems in order to reduce dry spots within highly managed turf areas and/or lawns. The inventive formulation comprising multi-branched surfactant compounds with both hydrophobic and hydrophilic constituents within each branch attached to an oxygen-containing polyfunctional base compound permits effective moisture penetration through such localized dry spots for sustained grass growth therein. Importantly, such multi-branched wetting agents provide sustained moisture penetration over a sustained period of time since the individual branches of such compounds may become dissociated from its base polyfunctional compound. Since such branches include both hydrophobic and hydrophilic constituents themselves, and thus act as wetting agents, even after degradation of the initial surfactant compound, long-term wetting and moisture penetration, at least, are permitted. Methods of treating sandy soils with such compounds and formulations thereof are also contemplated within this invention.

Abstract: Joint filing sands for concrete and other paving stone arc known to act as substrate for weed growth. The present invention drastically reduces the necessary weed control work by making the joint filling sand a hostile substrate for plant and fungus growth by The use of environmentally acceptable slow release mineral additive. The additive having similar grain size distribution and with similar mechanical and rheological properties forms an integral part of the joint filling sand. The specific gravity of the additive is lower than quartz sand imparting a tendency for the additive to migrate towards the top part of the joint. The additive leads to pore waters being rich in sodium and at high pH, both qualities being maintained over long periods of time. The mixture of additive and sand can be handled and applied using conventional laying techniques and equipment, observing usual precautions as used for mortar or cement mixes with sand. In the environment, reaction with CO2 in the air or in the soil porosity will inactivate the causticity, yielding harmless carbonate salts.

IPC: G06F21/53
Filed: 2006-05-12
Abstract: The invention discloses a method and system for protecting a computer platform from malware. The protection is achieved by encapsulating an application that can serve as a malware conduit within a protected capsule environment, so as to prevent the conduit application or any processes originated therefrom from accessing and making changes to objects associated with an operating system (OS) of the computer platform or with other applications running on the computer platform outside of the capsule environment, thereby preventing the malware provided via the conduit application from contaminating the computer platform outside of said secure protected environment, or capsule.  Capsule runtime software manages the dynamic state of the encapsulated application, and re-directs system service requests generated by the application and associated processes from OS-provided system objects to corresponding object libraries provided within the capsule object set, so that any malware induced changes remain local to the capsule. Protection of the operating system and most applications running on the computer platform is thus provided by the isolation of the conduit applications within a secure capsule environment, which can be safely removed from the computer platform, together with any changes introduced by the malware to the computer platform, without affecting the computer operation.

Title: Web-fed rotary press having sleeve-shaped printing blankets
Inventor: KNAUER PETER
IPC: B41F7/02
Filed: 2006-05-18
Abstract: A web-fed rotary offset press is disclosed. The press is designed for using sleeve technology, it being possible for sleeve-shaped rubber blankets to be pushed onto the rubber-covered cylinders in the axial direction. Finite printing plates are placed onto the plate cylinders in a conventional manner, it being possible to fix the ends of the finite plates in slots of the plate cylinders. Rubber-covered cylinders are used which have a double circumference, while the plate cylinders have a single circumference. As a result, the rigidity of the cylinder system is increased substantially, with the result that a stable web run and in-register printing are possible in wide machines over 1400 mm, without it being necessary for modifications to be performed on the cylinders or the compressibility or thickness of the rubber layers of the sleeves to be changed in the axial direction.
