Granted: 2007-04-11
Abstract: The method involves providing a close area radio cell with a base station, transmitting log-on messages to the base station from subscriber terminals newly entering the cell. A radio call message is transmitted from the base station to already logged-on subscriber terminals, in response to the receipt of a log-on message or log off message, and for adapting locally stored network subscriber lists. Communications software is transferred, preferably driver software, from a newly logged-on terminal to previously logged-on terminals, enabling use of the services of the newly entered terminal. The transfer may or may not involve switching by the base station. An Independent claim is also included for a digital European cordless telephone (DECT) base station for a wireless network

Abstract: The inner core (6) of the mattress is made of an airtight synthetic material, which is inflated. It is covered with a fleece (23,24) and an outer layer of thin plastic foil (13), leaving a surrounding gap (7). When the foam material (5') is applied to envelop the inflated element, it sticks to the area not covered with the foil (13) before, while all other areas slide freely inside the foam cover (15). The mattress offers a perfect combination of elasticity and support. No elastic bed base is needed.

Abstract: A method of screening for fetal Down's syndrome is described. Screening marker levels are measured. These may be measurements of a biochemical marker in a maternal sample or measurements of a marker from an ultrasound scan. The marker levels are used to calculate a risk of Down's syndrome. Instead of using markers from a single stage of pregnancy, the method uses markers from two or more different stages of pregnancy, typically one being in the first and another being in second trimester. The method may be automated.

Abstract: A method for producing a foam-containing structure. In a first embodiment, a defoamer is applied to the inner surface of an impermeable carrier. A foamed resin is introduced inside the carrier and contacts the defoamer to form a liquid resin layer on the inner surface. The foamed resin and liquid resin layer are cured to produce a foamed resin inner core and a solid resin outer layer. In a second embodiment, a permeable carrier is covered with an impermeable release material. A defoamer is applied to the carrier. A foamed resin is introduced inside the carrier and contacts the defoamer to form a liquid resin layer impregnating the carrier. The foamed resin and liquid resin layer are cured to produce a foamed resin inner core, the carrier as a facer material, and a solid resin layer impregnating the carrier. In a third embodiment, a defoamer and a catalyst are applied to a permeable carrier. A foamed resin is introduced inside the carrier and contacts the defoamer to form a liquid resin layer impregnating the carrier. At least a portion of the liquid resin layer contacts the catalyst and cures into a solid resin layer. The foamed resin and any uncured portion of the liquid resin layer are cured to produce a foamed resin inner core, the carrier as a facer material, and a solid resin layer impregnating the carrier.

Abstract: To treat heterogenous structures such as FRP moulded products, such as boat hulls, where the structure of the FRP laminate has been damaged, eg by water penetration, a layer of impermeable sheet material is first secured to a surface of the product to be treated to enclose a space between the surface and the layer. The contents of the space are continuously evacuated, for example by a vacuum pump, and then heating is applied within the space. A spacer is provided within the space to hold the sheet material away from the surface when vacuum is applied. After the treatment is competed, the heater is switched off and the vacuum released, the sheet is removed by peeling it away from the surface. The sheet can then be reused. The combination of the heat and vacuum it is claimed is sufficient to stabilise the deteriorating structure and allow restoration to its original condition.

Filed: 1993-06-07
Granted: 1996-12-30
Abstract: This is an automatic machine which sharpens the chains of chain saws used to cut trees. The most obvious difference compared to existing designs consists in the fact that the sharpening is automatic, unlike what occurs with commercial chain sharpeners which call for manual sharpening, one cutting edge at a time. There are various design features that are absolutely innovative as listed hereafter: the chain is positioned by a pneumatic chain stretcher, two sensors identify the position of the right or left cutting edge being sharpened and, consequently, the abrasive grinding motor assembly, which is adjustable, is oriented and then descends to perform the sharpening of the edge. Both the chain stretcher and the sensors and the adjustable grinder motor assembly are absent from all existing chain sharpening machines, and on the other hand their joint utilisation allows the realisation of the automatic machine. <IMAGE>
