Title: A method of effecting random access in a mobile radio system
Inventor: DAHLIN JAN ERIK AAKE STEINAR
IPC: H04W72/14
Filed: 1993-10-12
Abstract: A method for random access in a time divided mobile radio system, for instance an FDMA/TDMA system, which includes digital traffic channels and control channels which are organized so that four traffic channels and two control channels are included in a TDMA-frame. A base station transmits continuously flags in the time slots of the control channels. A mobile station desiring access to the system responds by sending a first message word in the time slot indicated by the base station in a first flag. When the mobile station wishes to transmit several message words, the base station reserves one or more time slots to this end by transmitting the first flag, although this flag now states that these time slots are busy for other mobile stations.      Furthermore, the base station transmits a flag which states whether or not a message word has been received from the mobile station. The base station can transmit a further flag, which denotes that a given time slot has been reserved for a given mobile station from the very beginning of an access procedure and cannot therefore be used by any other mobile station.

Filed: 1994-06-28
Abstract: ABSTRACT            A method is provided for prefitting a stiffened member to a curved body having a geometry approximatable by a cone. Two points are initially selected on the surface of the body which also lie on two different planes passing through the body, such that the intersection of the surface and the planes defines two closed curves. A cone is approximated based on parameters relating to the curves and the selected points. A three-dimensional pattern of a stiffened member is then superimposed onto the conical surface at a modelling position corresponding to the desired placement position of the member on the body. The geometry and dimensions of the pattern are mathematically specified relative to the conical surface and the specifications provide a model for fabricating the prefitted stiffened member.

Title: Method for preserving wood against undesirable reactions caused by microorganisms
Inventor: SILENIUS PETRI
IPC: B27K3/34
Filed: 1994-03-31
Abstract: The present invention is related to a method for preserving wood against undesirable reactions caused by microorganisms. The invention also concerns wood preserved against molds, blue-stain fungi and rot fungi. According to the method, the wood being preserved is treated with a substance capable of inhibiting the growth of microorganisms, whereby said substance is penetrated into the wood at least essentially deeper than superficially. According to the invention, such a substance used in the method is a complexing agent, e.g., EDTA, which is capable of binding transition metals contained in the wood, whereby the complexing agent is first impregnated into the wood in a water-based solution, and subsequent to the impregnation step, the complexing agent impregnated into the wood is precipitated from the aqueous phase. The complexing agent can be precipitated by, e.g. lowering the pH of the wood, or alternatively, altering the temperature of the wood after the impregnation step. According to the invention, the complexing agent precipitated into the wood forms a reserve depot, whereby the substance re-dissolving from the depot is capable of binding transition metals entering the wood via rainwater or contamination.

Filed: 1995-06-16
Abstract: A rod that can be used to dry clothes, towels and the like. The rod is readily adjustable in length so as to be frictionally lockable in a substantially horizontal position between a pair of opposed wall surfaces. The rod has a main hollow tube made of a substantially rigid material and at least one hollow tubular segment which can be used to vary the lenght of the rod. The rod also has a connecting component. The connecting component has an insertable segment and an integrally extending protruding segment. The insertable segment is configured and sized so as to be slidably and fittingly insertable into both the main tube and the tubular segment. A first tip component is releasably fixed to the protruding segment. A a second tip component is releasably fixed to the main hollow tube. The insertable segment is inserted into both the main hollow tube and the tubular segment with the tubular segment positioned between a distal end of the protruding segment and a proximal end of the main hollow tube. The lenght is modified by adding or subtracting hollow tubular segments. This length adjustment method is paticularly adapted to allow for an adequate length of adjustment while also ensuring that the predetermined length of the rod will remain constant. Since the adjustment method allows for a rod having a constant predetermined length, the tip components will always be firmly pressed agaist the wall structure and thus the rod will be firmly supported.
