Filed: 2000-04-27
Granted: 2005-11-22
Abstract: The present invention relates to a bale wrapping implement adapted for being coupled for trailing a baler and being of a simple construction. This invention is realized by constructing the wrapping implement so as to have a main frame that includes first and second frame sections, with the first frame section carrying a bale wrapping device and including a forward end defined by a coupling, which allows the main frame to pivot vertically when coupled to the baler, and with the second frame section carrying a bale-support structure and being coupled to a rear region of the first frame section for horizontal movement between a bale-receiving position close to a rear end of the baler, and a bale-wrapping position spaced from the baler. A main support wheel is mounted to a rear region of the first frame section.

Title: Echo canceller employing dual-h architecture having improved coefficient transfer
Inventor: YOUNCE RICHARD C
IPC: H04B3/23
Filed: 1998-11-13
Granted: 2007-08-21
Abstract: An echo canceler circuit (25) for use in an echo canceller system is set forth. The echo canceller circuit (25) comprises a first digital filter (35) having non-adaptive tap coefficients to simulate an echo response occurring during a call. A second digital filter (30) having adaptive tap coefficients to simulate an echo response occurring during the call is also used. The adaptive tap coefficients of the second digital filter (30) are updated over the duration of the call. A coefficient transfer controller is disposed in the echo canceller circuit (25) to transfer the adaptive tap coefficients of the second digital filter to replace the tap coefficients of the first digital filter when a value, E(~), is greater than a value E(-), and concurrently, when E(~) is greater than a value, E(sub max). The value of E(-) corresponds to the ratio between the signal-plus-echo signal and a second echo compensated signal using the second digital filter.

Abstract: The clasp for use with an adjustable length strap of the type used on a golf bags, back packs and the similar articles includes a housing having a open passage and a blind compartment in stacked relationship with respect to each other and a hinged lid overlays the blind compartment. The strap has a first end fixedly attached to the article and is positioned to slidably extend through the open passage of the clasp. The free end of the strap is looped through a ladder-lock buckle or similar device carried on the article, and the looped-over portion of the strap is placed in juxtaposed overlaying relationship with the main portion of the strap, and the free end of the strap is placed in the compartment of the clasp and held therein by closing of the hinged lid. Adjustment of the strap to a desired length is accomplished by sliding movement of the strap through the ladder-lock buckle so as to either increase or decrease the length of the main portion of the strap and this is accomplished without disturbing the clasp in that the strap is slidably movable through the passage formed in the clasp.

Abstract: An apparatus of a muntin bar clip (1) to secure the position of muntin bars (65) during and following the fabrication of multi-pane sealed glass window units (70). The disclosure relates to securing and positioning muntin bars (65) at multi-pane sealed glass window unit (70) perimeters and in joining hollow false muntin bars (65) within such units. The invention relates particularly to muntin bar clips (1) intended to fix the position of hollow false muntin bars (65) at the perimeter of the window unit (70) utilizing the sealing methods including foam strips (80) and or butyl (82) as the sealing medium. The disclosed invention more particularly relates to muntin bar clips (1) for the purpose of fixing the position of hollow false muntin bars (65) at the perimeter of the window unit (70) where the false muntin bar (65) is other than orthogonal in relation to the perimeter of the window. The invention more specifically provides the fixing of the position of muntin bars (65) to lessen the likelihood of either breaking or cracking the glass panes (71), as multi-pane sealed unit (70) occurs, or of causing seal failure of such units either during manufacture or following installation.

Abstract: L'invention concerne un procédé et un appareil conçus pour accroître la sécurité des réseaux informatiques par le biais de l'utilisation d'un système de dissuasion contre les intrusions et usages abusifs (IMDS) (65) fonctionnant sur le réseau (10). Il s'agit d'un système qui permet de créer un réseau de synthèse complet comportant des hôtes et des routeurs de synthèse (20). Il comprend un serveur réseau avec logiciel d'application associé qui apparaît être, pour un intrus, une partie légitime d'un réseau réel. L'IMDS demande alors des renseignements et détourne l'intrus du réseau réel (40). Des services simulés sont configurés de façon à apparaître fonctionner sur des clients virtuels (30A-E) ayant des adresses IP de classe "C" globalement uniques. L'utilisateur légitime du réseau virtuel (60), simulé par l'IMDS, n'existant pas, on doit considérer toute cette activité comme inappropriée et la traiter comme telle. En conséquence, on peut recueillir et identifier toutes les transactions effectuées par un intrus et non plus seulement celles qui correspondent à un profil d'attaque prédéfini.

Abstract: A bed assembly (1) for altering the position of a person supported thereon, includes a longitudinal support frame (5) having a support surface (23) for a person and a longitudinal cradle means (4) extending over the support surface. The cradle has a recess (10) extending along side portions of the cradle in the longitudinal direction.  The recesses are adapted to receive and engage cradle support engaging means (7, 7a). These means are mounted to the support frame in close relation to the recess and adapted to be extend-able and retractable in engaging relation within said recess so as to promote a change in configuration of the cradle. A first actuator (3) is disposed beneath the support frame and coupled to the engaging means for extending or retracting the engag-ing means. In a first condition the actuator causes the engaging means to extend towards and be received by the recess, causing the cradle means to move between a position of rest and a concave configuration about the central longitudinal axis. In a second condition, the actuator causes the engaging means to retract, returning the cradle to the rest position. Movement between the two conditions being controlled continuously, staggered or cyclicle so as to aid movement of the person lying on the support surface.

Abstract: The device for conveying flat objects edge-on in series at high speed between an entry (A) and an exit (B) of a conveying path comprises a routing system for diverting some of these flat objects towards another exit (B') between the entry and the exit of the conveying path. This system comprises two mobile flaps (3, 4) kept mutually parallel and arranged between the entry and the exit of the conveying path, and two motorized endless belts (1, 2) moving between these two flaps and between which the flat objects conveyed are gripped, these two flaps being mounted so that they can pivot so as to route the flat objects either towards the exit (B) of the conveying path or towards the other exit (B'). A  stationary post (6) is located at the point where the flat objects are routed downstream of the mobile flaps between the entry and the exit of the conveying path. The exit (B) of the conveying path is distant from the stationary post (6), and one (1) of the motorized endless belts extends beyond the stationary post as far as the exit of the conveying path, and this makes it possible to ensure the continuity of the conveying of the envelopes exiting the routing system.

Abstract: An improved method for supporting an underground pipeline in an excavated trench is disclosed. The method involves supporting the pipeline on specially-designed support benches at spaced intervals. The benches are designed to fail when exposed to a predetermined load, which load will be placed on the benches at some point during the backfilling of the trench or when the pipeline undergoes hydrostatic testing.  When the benches fail, the fill under the pipeline is compacted and thereby supports the pipeline in lieu of the support benches.
