Patent GB-2263589-A (GB)
Title: Cable joints
Inventor: PAWLEY RONALD JAMES ELLIOTT
IPC: H02G15/184
Filed: 1993-01-15
Abstract: An electrical cable joint comprises at least one joint between line or phase conductors of the jointed cables that is surrounded by an insulating sleeve and encapsulated with it in a body of polymeric material which has electrical properties inferior to those of the sleeve (either inherently or because it contains air-filled voids). This body may be of low-grade casting resin, or it may be a heat-shrink sleeve. The sleeve is of composite construction and comprises:      an outer layer (11) of electrical-grade insulating material; an intermediate layer (13) being an electrode of semiconducting material which terminates short of the ends of the outer layer; and an inner layer of electrically-insulating material which completely covers the intermediate layer. Internal and/or external ribs are provided on the sleeve. The outer layer is thick enough to withstand the whole conductor-to-earth potential, and the inner layer a substantial fraction of it. In this way the need to connect the electrode to the conductor is eliminated and some departure from concentricity can be tolerated. <IMAGE>

Title: Self-diagnosis in digital signal processing systems
Inventor: FUKUI TAKAO
IPC: G11B20/18
Filed: 1993-03-24
Abstract: The invention provides a self-diagnosing method and a digital signal processing system having a self-diagnosing function. The system comprises a digital signal processing apparatus including a plurality of electronic parts for processing signals of a plurality of channels. An output of the digital signal processing apparatus is coupled to an input of the apparatus. A central processing unit causes one after another of the electronic parts to generate a predetermined signal while the other electronic parts are in a condition in which the predetermined signal passes therethrough, and checks whether or not the output of the digital signal processing apparatus is correct. When the output of the digital signal processing apparatus is not correct, the central processing unit outputs a unique reference number of the electronic part from which the predetermined signal is generated then. The reference number of the electronic part is visually indicated on a bar graph meter. <IMAGE>

Title: Computer-controlled multi-media processing device
Inventor: KAWAHARA YUZO
IPC: G06K7/00
Filed: 1993-04-08
Abstract: A computer-controlled multi-media processing device (21) is provided with a top-loading CD-ROM reader (23), a ROM cartridge reader (25) mounted on the cabinet (23c) of the disk reader, the ROM cartridge reader (25) being arranged to receive an IC card, ROM cartridge or the like (24) and being coupled to CD-ROM reader (23) by connectors (40, (41), and a computer controller contained in the cabinet (23c) or (25B) of one of said readers for selecting from the readers. With this arrangement the size of the device is reduced in comparison to conventional devices. Because the disk reader (23) is top- loaded, it is also possible to decrease the manufacturing costs of the device by simplifying the loading operation and minimizing the number of required parts and assembly steps. Furthermore, because the computer controller is installed in the cabinet of either of the readers, it is possible to make the device as a whole more compact. A variety of configurations of the device (21) are described. <IMAGE>

Title: Zoom lens barrel with focal length detector
Inventor: NOMURA HIROSHI
IPC: G02B7/10
Filed: 1993-04-15
Abstract: A zoom lens barrel comprises a focal length code plate 36 secured to a fixed lens barrel, and brushes 41 secured to an axially movable guide ring. The brushes have elastically deformable legs to contact a terminal portion 37a of a flexible printed circuit board 37 so that detected focal length data can be transmitted to a camera body, and deformable legs for contacting the code plate. Rotation of a screw 33 against the bias of spring 30 can adjust the relative position of the code plate and the brushes, the deformable legs sliding over the board 37 and code plate 36. A restricting wall 39 limits the restoring force at the free ends 41b of the brushes. <IMAGE>

Title: Improvements in or relating to gyroscopic devices
Inventor: BURDESS JAMES STONEHOUSE
IPC: G01C19/574
Filed: 1992-05-22
Abstract: A gyroscopic device comprising a supporting structure (2; 104) and at least one mass (1; 50, 51; 100 - 103), the masses being attached to the structure by beams (3 - 6; 25 - 28; 52 - 63; 98 - 99). Masses, supporting structure and beams lie within a common plane when the device is at rest. There are means (V) to generate electromotive forces between such masses and structures to excite the masses into a vibratory primary motion. By simple flexure the beams can permit the masses to make limited motion relative to the structure in response to a rate of turn applied to the device, a measure of that rate being obtained from sensing that relative motion. By appropriately arranging the flexural connections (85 - 88) between the mass and the supporting structure, the device can measure rates of turn about two orthogonal axes. By connecting the supporting structure (104) to further structure (112) by means of further flexural members (113) the device may be made capable of measuring rates of turn about three orthogonal axes. <IMAGE>

Title: A district heating pipe stretch and a method of establishing such a stretch
Inventor: PEDERSEN HANS NOERGAARD
IPC: F16L59/20
Filed: 1994-06-15
Abstract: Conventionally designed district heating pipes assembled from prefabricated heat insulated pipe elements (2, 4) are not well suited for being mounted in the underground by the so-called horizontal drilling technique, because the associated exterior sealing sleeves (16) arranged over the pipe element joints may be axially displaced if they meet with obstructions during their insertion through the subsoil bore. According to the invention, the conventional joints may still be used, if only the said sleeves, with reduced diameter, are mounted between narrowed ends (12) of the exterior mantle pipes (10) of the pipe elements (2, 4). <IMAGE>
