The funnel is mounted in the lid, the swivel launder is mounted under the lid and the intermediate hoppers are positioned radially in the housing to form a cavity by hopper surfaces facing a longitudinal axis of the installation, said cavity being separated from the interior of the hoppers, which are coupled to the pipe chute by discharge openings formed therein and shutters mounted to move relative to a longitudinal axis of a hopper.

Abstract: A multiuser detector method and receiver that detects and decodes synchronous or asynchronous CDMA subchannels having different spreading factors with reduced computational complexity. The multiuser receiver is compatible with ZF-BLE, MMSE, decorrelating detectors and the like using Cholesky decomposition to minimize numeric operations. The receiver and method arranges the columns of system transmission response matrices representing the response characteristics of individual users into a total system transmission response matrix which represents a plurality of matched-filter responses for a given block of received data. The invention when used in conjunction with Cholesky decomposition reduces the number of required mathematic operations prior to parallel matched filtering.

Abstract: An anti-vibration unit serving as a driving apparatus has an X axis transducer having a driver, a fixed frame having an X axis transducer holding part, an X frame having a sliding body against which the driver is pressed by a pressing plate with an anti-vibration sheet and a holder interposed therebetween, a Y axis transducer having a driver, and a Y frame having a sliding body against which the driver is pressed by the pressing plate with the anti-vibration sheet and the holder interposed therebetween. The anti-vibration sheet is narrower than the transducer, and grease is applied to one of the surfaces of the anti-vibration sheet and the pressing plate in contact with each other, so that the drivers are in proper contact with the sliding bodies, and the sliding bodies are efficiently driven. The driving apparatus is compact and produces high driving force with high efficiency.

Abstract: A forming section for a gap blade former type papermaking machine having a headbox which delivers a jet of papermaking stock between a conveying forming fabric and a backing forming fabric is provided. The conveying fabric moves in sliding contact over an impingement shoe on which the jet of papermaking stock is delivered at a point of impingement. A forming shoe located immediately downstream of the impingement shoe over which the backing forming fabric slides. The impingement shoe is mounted for at least one of pivoting and transverse movement so that a position of the point of impingement of the jet of papermaking stock can be adjusted by at least one of rotating the impingement shoe about a first pivot point and transversely shifting the impingement shoe. The forming shoe can also be mounted for movement.

Abstract: The present invention refers to equipment, for the recharging firearm cartridges, having four modules that can operate jointly or separately. The equipment includes a calibrating press, that calibrates and removes a deflagrated fuse of the case through the movement of the piston tool ports and a washing turbine having a rotating nucleus that moves angularly between 90 and ?90 degrees to facilitate loading, washing and discharging of the cases. The equipment also includes a fuse press for fuse assembly in the case, with automatic rejection of the defective cases through pneumatic auxiliary cylinders of high sensitivity. The press includes a case feeder system; a rotating disk; and a reservoir feeder of fuses. The press also includes a dosage press for the assembly and packing of the cartridges, with movements synchronized vertically, circular and lineal, with main cylinder and commanded by panel provided with commands for control of the gunpowder dosage.

The first machining tool (2) and the second machining tool (3) are arranged in relation to one another in such a way that the first axis (A) and the second axis (B) lie on a common plane (E) and/or that their respective workpiece machining zones (I, II) at least partially overlap one another in the transversal direction of the tree trunk or adjoin one another.

Abstract: The procedure for feeding balls (14) to the projectile chamber (11) of a handgun (1), in particular to the projectile chamber of a paintball weapon, whereby the balls (14) are fed by means of a motor from a ball container (3), through a feeder tube (2) into a projectile chamber (11), is characterized by the fact that the motor is controlled as a function of the movement of the balls (14) in the feeder tube (2). The feeding of the balls (14) to the projectile chamber (11) is controlled in accordance with the procedure which is the subject of the invention. The invention has the advantage that the motor is controlled as a function of the actual conditions prevailing inside the feeder tube (2).

The JD receiver has a plurality of channel estimators that estimate received signals within a common timeslot and a combiner configured to decode and combine the channel estimates to derive a resultant data signal.

Abstract: Method and apparatus for performing midamble cancellation to remove midamble interference from the convolution tail of data field 1 and the first W?1 chips of the midamble field which results from the delay spread of the multipath channel and for canceling the first W?1 chip midamble spread in the data field 2, which operations are performed substantially simultaneously. The received burst, typically a TDD burst, is stored, the midamble interference and the corresponding parts in the received burst is removed and the resulting burst is applied to a multi-user detector to obtain the symbol sequences.
