Patent SE-8102048-L (SE)
Inventor: FALCONER D D
IPC: H04B3/23
Filed: 1981-03-31
Abstract: A full-duplex, two-wire Nyquist sampled data communication system includes an adaptive echo canceller (24) at each terminal (e.g., 10'). The echo canceller generates a replica (zm) of the echo component of each sample (rM) of the incoming signal. The replica and the sample are subtractively combined to provide an echo compensated signal (SM). During intervals of simultaneous transmission and reception, i.e., double talk, the echo compensated signal may contain not only an uncancelled echo component but also a far-end data component. An adaptation error signal generator (80), operating in response to a stream of recovered data symbols (e.g., ân), estimates and removes the far-end data component from the echo compensated signal and, in response to the difference, generates an adaptation error signal ( gamma EM-D). This signal is applied as an error signal to the echo canceller. This allows the echo canceller to adapt its set of tap coefficients in response to the uncancelled echo component present in the echo compensated signal. Thus, stable and accurate echo cancellation results even during a double-talk interval. <IMAGE>

Abstract: An industrial robot having several axes of freedom of movement comprises an operating members supporting arm (16) pivotally mounted at the top of a supporting column (14) for movement about a horizontal axis from a horizontal angular medium position under the control of a linear actuator (32) pivotally connected at one end to the supporting column (14) and at the other end to the supporting arm (16). As shown the linear actuator is an electromechanical jack having a worm (54) and lead nut (58), the worm (54) being rotatably mounted within an elongated housing (44) and driven by a motor (34) secured to the housing (44) and the lead nut (58) being coupled to an outer tubular jacket (68) through slots in the housing 44 by keys (60, 62). The nut (58) may have recirculating balls. The upper end of the jacket (68) is closed by a cap (70) to form a cylinder within which slides a piston formed by a disc (78) secured to closure cap (48) of the housing (44). A gauged hole (88) is provided in the cap (70) so that air in the cylinder acts as a shock absorber. Springs (84, 86) are mounted at the ends of the worm (54). <IMAGE>

Abstract: A method is disclosed for providing optimal compaction of various materials by controlling the vibration amplitude of an adjustable amplitude vibratory roller. The vibration amplitude is automatically reduced when excessively high jolting forces are sensed by transducers carried by the roller or its frame. The apparatus for carrying out the method includes a continuously adjustable eccentric element in the vibratory roller, at least two signal transducers mounted on the roller drum or frame and axially separated, to generate signals representing the vibrational movement of the roller. A regulating system responsive to the signals from the signal transducers reset the adjustable eccentric element to vary the vibration amplitude and provide optimal compaction.

Abstract: Such devices usually have a suction opening on the underside of a suction head, which is surrounded by a ring shaped tightening material. Due to the unevenness of the upper side of the sack difficulties can arise when placing the tightening material against the sack.According to the invention, the upper part of the tightening material (6) is placed in a ring shaped track (5) between two ring shaped chambers (7, 8) jutting downward from the suction head with lower, rounded off edges, to which the rounded off edges or the outer chamber (8) preferably jut of farther from the suction head (2) than the rounded off edges of the inner chamber (7). The purpose of the chambers (7, 8) is to produce a ring shaped, even impression in the sack that makes tightening the material against the sack easier.<IMAGE>

Abstract: In a device for joining building elements (A, B), an overlapping joint is included between tow corrugated surface plates (3). The joint consists of an upper section (14) and a lower section (16) in an overlapping relationship with each other. The end (22) of upper section (14) is bent inwards and the height of the upper section (14) at the end (22) is less than the maximum height of the lower section (16). The lower (14) and the upper (16) section belong to the first (A) and second (B) building elements respectively. The two building elements are designed to form a known tongue and groove joint to each other in the direction of the main plane of the elements (A, B) and at right angles to the extension of the wave crests and troughs of the surface plates (3). In order to make the aforementioned groove and tongue joint possible, the lower section (16) is designed with obliquely inclining sliding plane (18) in the opposite direction to the other element (B) on and along which the end (22) of the upper section (14) is offset over the lower section (16) during the jointing of the elements (A, B). The purpose of this is to create the aforementioned overlapping joint as the same time as the groove and tongue joint is formed.<IMAGE>

Abstract: The subject matter of the invention is a driving apparatus for fasteners each of which has a shank and a head, and a characteristic of the invention is that a feeding mechanism for feeding fasteners from a magazine for a row of fasteners to a laterally offset firing track in the apparatus is in the form of a reciprocatory slide the path of movement of which is perpendicular both to the row of fasteners and to the fastener firing track of the apparatus, that the slide has two opposite arms with oblique end surfaces forming a gate device which is movable during the movement of the slide to allow one fastener at a time to pass from the magazine to the firing track, and that one arm of the slide serves as a separating means which during the movement of the slide in one direction is moved in between the fastener introduced into the gate device and the next following fastener so that these fasteners are separated from one another, and which at the same time positively moves the fastener introduced into the gate device through the gate device to the firing track under the collaboration of a stationary stop means which prevents the fastener introduced into the gate device from moving together with the slide.

Abstract: The present invention concerns a rail for track-bound and wheel-mounted vehicles, which rail consists of a support flange, a web and a rail head constituting the contact surface for the wheels. In connection with track-bound traffic, it is in many situations desirable to reduce external noise, internal noise, internal vibrations and external ground vibrations. By means of the fact that the contact surface of the rail head 3 has one or more grooves 4 which run parallel to the rail and into which there is pressed a profile strip 5 of hard polymer material, which strip 5 completely fills the groove and projects slightly from the contact surface of the rail head, it is possible to reduce these disturbances. <IMAGE>

Abstract: A gear wheel drive air compressor which is constructed as a piston compressor, the drive gear wheel of which on the air compressor crankshaft meshes with a gear wheel on the camshaft of the internal combustion engine. The inventive construction prevents the reverse acceleration of the camshaft drive gear wheel and minimizes the knocking pulse and noise in the mesh of the camshaft gear wheel in that the transmission ratio between the air compressor drive gear wheel and the camshaft gear wheel is embodied as a multiple load cycle of the camshaft drive torque, and at the same time the angular position of the air compressor crankshaft relative to the camshaft is fixed such that negative torque components of the air compressor crankshaft are eliminated by the overlapping of positive torque components of the camshaft. Furthermore, the air compressor drive gear wheel is arranged in alignment with the air compressor crankshaft.

Abstract: A cycloconvertor (SC) transmits power between a three-phase network (N1) and a single-phase network (N2) with a lower operating frequency than that of the three-phase network. The cycloconvertor is of two-phase design on the secondary side, that is, generates a two-phase alternating voltage system on its terminals (A, B, NP) facing the single-phase network. The single-phase network is connected to two of these terminals. Between these two terminals (A, B) and the third terminal (NP), controllable reactive power members (TAC, LAC; TBC, LBC1, CBC, LBC2) are connected. A control device (CD) is adapted to control the reactive power members for symmetrization of the load of the cycloconvertor.
