Title: Improvements to systems for discharging sacks in packaging machines.
Inventor: BAUTISTA MANUEL PADULLES
IPC: B65B61/28
Filed: 1998-02-04
Abstract: One of the improvements of the invention is to give the sacks (3) at the time of closing and releasing them, an inclined position, with the open end in a forward position with respect to the base or lower end of the sack, the inclination of the sack being obtained by controlling the intermittent motion of the sack clearing conveyor belt (2), in such a way that, after releasing the closure mechanism, the inclination of each sack (3) is sufficient to tilt the sack by gravity until it rests upon the sack which is immediately before, the inclination of the sack (3) being slow and progressive, without stress in the closure seam (6), stress which could cause the breaking of said sack. Another improvement concerns the conveyor belt (2) which is associated to a frame (10) vertically displaceable on a pair of side guides (13), so that the elevation of the frame (10) and, together with it, of the conveyor belt (2), provides for the adaptation of the installation to various sizes of sacks.
Patent MX-9805134-A (MX)
Title: Impairment determination for a diversity antenna selection process.
Inventor: TODD STEPHEN ROSS
IPC: H04B7/08
Filed: 1998-06-24
Abstract: A diversity selection process which tests to determine whether poor reception is caused by co-channel interference or multipath fading is disclosed. The impairment is determined by first testing the quality over several frames. Unless the quality is poor over these several frames, the system tests for multipath fading by selecting the antenna with the greater signal strength, provided no hold condition exists. However, if poor quality has been present over the several frame period, the system selects the other antenna if its RSSI is greater. However, the system also tests the RSSI received on the current antenna and determines the impairment was co-channel interference if the signal of quality was sufficiently high. In which case a hold condition is set for a number of frames to prevent excessive switching.

Title: Deep-drawing plastic foil containers - and placing wall reinforcing strips in movable deep-drawing forms at level below foil feed plane
IPC: B65C9/18
Filed: 1981-04-09
Abstract: The mechanism is intended for mfg. deep-drawn containers with composite wall from plastic foil. A continuous length of foil is moved step-wise to a deep-draw station having at least one row of hollow forms arranged below the foil. A separate continuous length of foil is fed from a roll and cut lengthwise into parallel reinforcing strips, which are formed into loops then cut across and placed in forms (by 12). These forms are movable step-wise across the foil transport direction for alignment with the loop-formers which are arranged below the level of the foil plane whilst the forms are vertically movable between a strip insert position and the deep-draw position above it. Used for making deep-drawn plastic foil containers with foil-reinforced walls. The novel positioning of the strip loop forming and inserting mechanism considerably reduces the amt. of travel required for the deep-draw forms as compared with the conventional placing to the side of the foil. As it is undesirable to increase output by increasing the speed of this travel (because of container contents at later station) this short travel is an advantage. The novel position also provides unobstructed view of the foil.
