Patent NL-9001361-A (NL)
Title: Fault detection system for single phase double insulated equipment - uses internal conducting screen and high impedance sensitive detection circuit
IPC: H02H3/14
Filed: 1990-06-15
Abstract: Electrical equipment (1) and an electronic switch (2) are connected to a single phase AC supply typically 220 volts via a bridge rectifier (3). An equipment housing is made from a sandwich material presenting insulating material inside and out (4) and a conducting screen (5) in the centre. A detector circuit (6) with high impedance is connected to the screen and the electronic switch. In the event of a fault or breakdown in one or both insulating layers conductivity across the sandwich layer increases resulting in a small fault current. This is registered through the detector circuit and results in a switching signal (7) from the electronic switch to isolate the equipment and an alarm signal (8).

Title: Method and extrusion tool for forming tubular profiles having a wall consisting of a plurality of layers from thermoplastic material
IPC: B29C48/09
Filed: 1992-08-14
Abstract: A method and extrusion tool for forming a tubular profile having a wall consisting of a plurality of layers from thermoplastic material. The extrusion tool comprises a separator 10 which can be connected to at least two extruders for forming a plurality of concentric plastic material streams having an annular cross section, and a die 12 which can be connected downstream to the separator, to mould the plastic material streams coming from the separator into a tubular profile. Downstream of the separator, the plastic material streams are brought together to form an assembly of layers. During flow through the die, seen in the downstream direction, the cross-sectional area of the assembly is first reduced and then briefly maintained in that state. Subsequently, the cross-sectional area is increased and then reduced.

Date Sep. 28, 1995A method for manufacturing biaxially oriented tubing from a thermoplastic material. The method includes forcing the tube over a mandrel at an orientation temperature of the plastic material, which mandrel is an expansion part which produces expansion in the circumferential direction of the tube. Downstream of the mandrel an axial pulling force is exerted on the tube, and the biaxially oriented tube is cooled down. At a distance downstream of the mandrel, the tube is drawn through a calibration opening bounded by a calibration device, the calibration opening being such that it produces a reduction in the external dimensions of the tube. Accurate regulation of the external dimensions of the tube is provided by regulating the distance between the mandrel and the calibration device, in particular depending on the external dimensions of the tube measured downstream of the calibration device.

Inventor: HARDENDOOD THEO
IPC: H04L12/28
Filed: 1994-10-04
Abstract: The invention relates to a system for digital communication of data divided into packets between at least two communication apparatuses via a network, said network comprising at least two media, wherein communication in the network is controlled by a network protocol and communication between the apparatuses is controlled by an apparatus protocol. Unabbreviated and complete transfer through the network of data and apparatus protocol information supplemented with network protocol information results in unnecessarily bulky packets, since at least some of the functions of the apparatus protocol are likewise executed by the network protocol, wherein the cost of the transfer through the network is directly proportional to the number of packets for transfer and the size of these packets. The invention has for its object to obviate the above stated drawbacks and provides to this end a system which is distinguished in that between the network and at least one of the apparatuses is placed a gate device which is adapted to code or decode the apparatus protocol information contained in a packet together with the data for transfer and to add network protocol information to the packet or remove it therefrom, and the system is further distinguished in that the gate device is adapted to transmit to an apparatus a confirmation to acknowledge receipt of a packet transmitted by this apparatus and to transfer the packet to the network for further transmission to the destination apparatus.

Title: Hockey stick
IPC: A63B53/14
Filed: 1989-09-04
Abstract: Hockey stick whose structure is formed by two components, the handle 1 and the blade 2 constructed separately and connected by means of the tenon 3 of one of the components inserted into a cavity in the other component. Both components are formed by the association of a certain number of bi-directional or uni-directional layers of a woven material reinforced with fibres of a stronger material which are bound together by means of a layer of synthetic resin which secures the relative position and the shape of the pieces. The handle 1 is hollow and filled with a mass 6 of a low-density material in order to place the centre of gravity of the device in the appropriate position for its use. The stick allows the static and dynamic forces which must be resisted to be fully compensated for, without risk of breakage, it being possible to work with forces of compression, flexure and torsion without detriment to its functional structure. <IMAGE>

IPC: H04L9/32
Filed: 1991-03-08
Abstract: A method for carrying out an authentication check in a mobile telephone system in which an authentic base station (BS) serves a plurality of mobile stations (MS1-MSn). It is earlier known to carry out a unidirectional check from the base station (BS) to a calling mobile station (MSk). A false base station (BSf) is able, in this way, to carry out a false authentication check, by collecting a number of so-called RAND-Response pairs. In order to avoid this, there is introduced a further unidirectional authentication check, base station-mobile station, and also an authentication check from the mobile station to the base station. According to one embodiment of the method, the unidirectional check is excluded and only the bidirectional authentication check is carried out. <IMAGE>

Abstract: The thread, the method and the fabric are applicable in theindustry for the production of special textile screeningprotection coatings and clothes. The thread has reduced breakageand extended application, by the method simplified equipment andnatural insulation threads of lower strength can be used. Thefabric made by such a thread is made in a simplified manner onstandard weaving looms and has improved protection qualitiesagainst noxious electromagnetic irradiation. The thread consistsof a metallic monofil thread around which screw-type insulationthread is twisted. The metallic monofil has diameter 0.06-0.15 mmand is made of copper being coated by insulation lacquer. Theinsulation thread is of natural origin: cotton, silk, woollen,linen, etc. The composite thread is twice twisted around themetallic monofil to 280-350 torque/m. By the method, the twistingof the insulation thread around the electroconductive one is alsomade simultaneously with the doubling of the electroconductingmonofil to the insulation thread. The feeding speed in doubling isup to 60 m/min. The twisting in the doubling is produced only byunwinding of the insulation thread from the bobbin and is from 35to 50 torque/m. The doubled thread produced is then subjected toadditional forced retwisting to 280-350 torque/m with supply speedto 4-5 m/min. The fabric is of weft and warp which are made of thecomposite thread with twisted electriconductive andelectroinsulation threads. This fabric can be made in twill weaveby a constant pitch for range of samples 1:1.
