Abstract: This invention concerns a device for heat treating a moving target area of biological tissues, comprising calculation means (6) for estimating the position of a target area using a measurement signal of the target area, characterized in that it comprises control means (7) for positioning a treatment focal point (P) in the target area based on the estimated position and a positioning time lag between a measurement of the measurement signal of the target area and the positioning of the treatment focal point (P), so as to compensate the movement of the target area during the positioning time lag. The invention also concerns a related heat treating method.

Abstract: The present invention relates to the use of an oxynitride glass comprising a combination of glass network modifying cations as an armour material. The invention further relates to a novel oxynitride glass comprising a combination of glass network modifying cations and to a novel method for preparing an oxynitride glass comprising a combination of glass network modifying cations.

Abstract: The invention relates to methods for treating scar tissue, wherein the scar tissue is covered with a masking element, and the masking element is pressed onto the scar tissue with an adjustable force by means of a pressure control unit and which is connected with inflatable or suction members in the masking element. The invention also relates to a device for treating scar tissue, consisting of a masking element which contacts the scar tissue, a supporting part which presses the masking element onto the tissue and means for adjusting the force with which the masking element is pressed onto the tissue. In another embodiment, the device is provided such that an active substance can be delivered in a controlled manner to the scar tissue through the inflatable or suction members in the masking element.

Abstract: A pair (1) of socks or stockings (2,3) may be joined together in a detachable fashion using a set heat-resistant, transparent fastening elements (4,5), in order to avoid sorting of the socks or stockings, e.g., after washing. Each of said fastening elements is firmly attached to a stocking or sock, preferably at its leg portion (6), in an area of the sock or stocking having a mesh density of at least 2000 MD, preferably at least 4000 MD.

Abstract: Air holding spaces are incorporated into a ring attached by arms to a driveshaft supported on sealed bearings in a vessel containing saline water. Air compressed by a blower or air compressor, powered by external power (i.e. prime mover), is injected into the air holding spaces by injectors. The spaces ascend due to their buoyancy, imparting a rotary motion to the driveshaft. Energy developed is transmitted through the driveshaft to an electric generator powering the system control computer, sensors and valves. Energy is also used to rotate a water pump which draws in saline water and pumps it to a saline water tank at the top of the vessel, where it circulates through an array of water holding tubes of thermally conductive material. Heat generated by the compression of the injected air is conducted to the saline water. This heat and the molecular agitation of the water by the ascending air causes the water molecules at the surface to evaporate into the vapor state.

Abstract: A steady state swimming pool heat exchanger designed to warm the water in swimming pools by the conducting of heat from the constant heat reservoir of the earth into the water in the pool through a heat-conducting rod sunk vertically into the earth beneath the pool. Attached to the rod is a contact plate, mounted on the floor of the pool, which transfers heat energy from the rod to the water. In temperate climates, the earth maintains a constant level of heat of 65 to 70 degrees at a depth of approximately 10 meters. The contact between the earth and the water in the pool provides a steady state transfer of heat to warm the water when the water temperature is below that of the earth reservoir. A non-conducting cover is provided to restrict the heat flux when heating or cooling of the water is not desired.

Abstract: A buoyancy engine having a plurality of vertically stacked drive units, immersed in a vessel of mercury, and rotatably mounted on axial drive shafts supported on sealed bearings in the vessel walls. The drive units are composed of capture modules, incorporating electromagnetic fields, fixed to the extreme ends of a plurality of arms extending from the drive shafts. The capture modules are designed to hold rigid-walled buoyant capsules injected through a pressurized airlock. When operating, drive units have capture modules moving upward, due to the buoyancy of the capsules, and empty capture modules moving downward. As a capture module containing a capsule reaches the top of its lifting arc, its electromagnetic field switches off and allows the capsule to be released into the next subsequent drive unit's lowermost capture module.

Abstract: A buoyancy engine having a plurality of pistons in cylinders is immersed in a vessel of liquid. A crankshaft is rotatably mounted on sealed bearings in the vessels walls. The pistons are attached to the crankshaft by connecting rods. The pistons are designed to hold relatively buoyant compressed air injected into them by computer controlled injectors. When operating, the crankshaft has one or more pistons moving upward due to the buoyancy of the air which they contain, and one or more empty pistons moving downward.

Abstract: A slide-type electrical switching mechanism has a contact plate with a plurality of frangible portions interconnecting discrete electrical contacts. The plate is securred to the non-conducting slider housing by deforming portions of the housing over the plate. The frangible portions are then punched out to form a plurality of discrete contacts for switching. The plate has contact connectors formed integrally therewith.

Abstract: A file cabinet and drawer each formed from a single sheet of cardboard, fiberboard, or like material with the file cabinet being formed to provide a housing for the drawer. The drawer being so formed as to have multiple layered front and rear walls and doubled panelled side walls with one of said panelled side walls providing an interior file carrier support.
