Abstract: The present invention relates to a demining system comprising a carrier vehicle (1) and a demining device (4) that operates in the ground in front of the vehicle and which device, driven by a motor mounted on the vehicle, rotates around a shaft (23) extending transversely and mainly horizontally to the vehicle. The purpose of the demining system in accordance with this invention is to clear large open areas of ground, including undulating terrain, from both buried and unburied mines. To achieve the necessary inclination of, and sufficient power to, the demining device it is powered by a motor mounted in the main beam across the vehicle which main beam connects the two longitudinal beams. The complete framework can then be laterally inclined and tilted relative to the vehicle (1) via a ball coupling (5) mounted close to the centre of gravity of the vehicle, while the lateral forces acting on the demining device are assimilated by a separate traverse steering unit (18-20) mounted between the demining device and the vehicle.

Abstract: PCT No. PCT/SE96/01606 Sec. 371 Date May 5, 1998 Sec. 102(e) Date May 5, 1998 PCT Filed Jun. 12, 1996 PCT Pub. No. WO97/23339 PCT Pub. Date Jul. 3, 1997In the manufacture of packaging containers, for example blown plastic bottles, a circular material blank is, in certain cases, fixedly welded to the end of a sleeve-shaped casing portion. It is advantageous from amongst other energy viewpoint if the welding can take place using ultrasound, but in this instance it has been proved that the central region to the circular blank absorbs ultrasonic energy to such an extent that it is deformed or breaks. A method of using ultrasound to fixedly weld a circular material blank without such drawbacks occurring is proposed according to the present invention in that the oscillations caused by the ultrasound are reduced by a mechanical stabilization of the central region of the circular blank, which is put into effect with the aid of a vacuum and a relief pattern provided in the central region of the circular blank. An apparatus for employing ultrasound to fixedly weld a circular material blank in place displays a counter abutment with a work surface for fixedly retaining the circular material blank, the work surface forming a part of a vacuum chamber, and support means for the central region of the circular blank during the welding cycle.

Abstract: According to the invention there is now provided a cemented carbide grade for rock excavation purposes with 96-88 % WC, preferably 95-91 wt-% WC with a binder phase consisting of only Co or Co and Ni, with maximum 25% of the binder being Ni, possibly with small additions of rare earth metals, for example Ce and Y, up to max 2% of the total cemented carbide. The WC grains are rounded because of the process of coating the WC with Co, and not recrystallized or showing grain growth or very sharp cornered grains like conventionally milled WC, thus giving the bodies according to the invention surprisingly high thermal conductivity. The average grain size should be 8-30  mu m, preferably 12-20  mu m. The maximum grain size does not exceed two times the average value and no more than 2 % of the grains found in the structure are less than half of the average grain size. <IMAGE>

Abstract: An antenna system (100) comprises a substantially planar electrically conductive ground plane (102) with an aperture (103), a substantially planar signal feed structure (104) parallel to the ground plane (102) and a substantially planar first dielectric layer (123) between the ground plane and the feed structure (104). The aperture (103) is in a shape of a first slot (105) orthogonally intersecting a second slot (106) at an intersection point (SIP). The feed structure (104) comprises a first feed unit (107) intersecting the second slot (106) asymmetrically with respect to the first slot (105), and a fork shaped second feed unit (108) comprising two feed arms (110,111). The feed arms (110,111) intersect the first slot (105) on either side of the slot intersection point (SIP), symmetrically with respect to the second slot (106). When used as a transmitting antenna, a first signal (Si) is fed through the first feed unit (107) and a second signal (S2) is fed through the second feed unit (108) to respective associated slot (105,106). The signals (S1,S2) excite the aperture (103) to radiate two substantially orthogonal linearly polarized signals.

Abstract: The position of an oblique mirror structure inside a polymer waveguide in relation to an optical device is accurately defined by using an integrated mask of metal, which is defined using photolithography, on top of the waveguide structure. When irradiating the surface of the waveguide with laser light, it is only let through where no metal is left, so that the recess formed is defined by edges of strips of the metal layer. In the same metal layer also electrical contact pads are produced used for self-aligning flip-chip mounting of devices such as lasers and photodiodes. Another metal layer can be applied inside the waveguide structure at a place under the waveguide core so that it is hit by and stops the laser light. The energy of the laser light will atomize the metal and the dispersed metal will then be deposited on the walls of the recess.

Abstract: In a front wheel suspension on a motor cycle (1), the front wheel is mounted in rearward-sloping supporting members (9) which, in turn, are mounted on the chassis (2) of the vehicle by means of or by bearing units (5, 10) comprising link elements and possibly a springing function. The supporting member and the wheel are turnable about a steering line (14) which slopes in a corresponding manner to the supporting members. The bearing units form separate upper and lower bearing units (5 and 10), which are provided with bearing members in or about which the said supporting members and the wheel are turnable. Preferably, the upper of the said bearing units acts as a combined bearing and steering linkage member for the supporting members. The bearing units are torsionally rigid in their respective planes, which extend through the respective securement points or bearings of the bearing units in the chassis and the said supporting members. The said upper bearing unit is arranged compliantly for torsion or turning motions which arise in the bearing unit when the supporting member and hence the wheel are allotted steering or turning motions or assume steering or turning positions which differ from the longitudinal axis of the vehicle. <IMAGE>

Abstract: FIELD: food industry. SUBSTANCE: method includes continuous introduction of hard elastomer, filler and oils into continuous-action mixer 10. Elastomer, filler and oils are subjected to dispersion mixing with subsequent distributive mixing. Continuous discharge of obtained chewing-gum base from mixer is performed along with introduction and mixing of ingredients. Oils are introduced into continuous-action mixer through great number of spatially-separated charging holes (12, 13, 14 and 15). Part of oils is preferably introduced into mixer along with hard elastomer and filler upstream from zone of dispersion mixing. Part of oils is also introduced into mixer downstream from dispersion mixing zone along production line, but upstream from distributive mixing zone. Thus chewing-gum base is produced (variants). Then chewing- gum composition containing this base is obtained (variants). As a result, continuous process of chewing- gum base production in continuous-action equipment is provided. In this case, multiple different bases of chewing gum are produced without restriction by type or content of elastomer used. At the same time elastomer does not require separate preliminary mixing or other preliminary treatment. EFFECT: enhanced efficiency. 46 cl, 36 ex, 5 tbl, 38 dwg
