Abstract: HOT CUT PROCEDURE FOR TELECOMMUNICATIONS NETWORK                  ABSTRACT OF THE DISCLOSURE         In a telecommunication network, having at least first and second original equipment electrically connected by at least a first existing conductor, a method is disclosed for adding intermediate equipment to the network. The intermediate equipment is connected to the first original equipment by at least a first replacement conductor and the intermediate equipment is connected to the second original equipment by at least a second replacement conductor.  A method for adding uses a temporary circuit having at least first and second test conductors.  The method includes the steps of electrically connecting first and second replacement conductors to the additional equipment.  The first temporary conductor is electrically connected to the original conductor at a first point of connection.  The second temporary conductor is electrically connected to the original conductor at a second point of connection.  The second point of connection is disposed between the second original equipment and the first point of connection.  The first and second temporary conductors and the first original conductor cooperate to define a temporary signal pathway between the first and second original equipment with the temporary signal pathway including the high temporary circuit.  The original conductor is severed at a point of severance disposed between the first and second points of connection.  The first replacement conductor is electrically connected to the first original equipment.  The second replacement conductor is electrically connected to the second original equipment.  The temporary signal pathway is severed.

Abstract: A trapezoidal non-pneumatic tire ("TNPT") is integrally molded from a stiff, resilient elastomeric material with particular specifications, to form a unitary structure comprising outer and inner cylindrical coaxial members ("hoops"), the outer being wider than the inner. The outer hoop is supported and cushioned by a plurality of circumferentially spaced apart, planar rib members (ribs) and a planar central web member (web) which connects the hoops at their circumferential center lines. The web lies in a plane perpendicular to the rotational axis of the TNPT. The ribs extend axially along the inner and outer hoops, connecting them, and the edges of the ribs lie along the opposite faces of the web. The ribs are angled in the range from 15° to 75° to radial planes which interesect them at their radially inner ends, and the ribs on one side of the web are angled oppositely from those on the other. A rubber tread is secured to the outer surface of the outer hoop. The coaction of the structural elements of the TNPT provides a load-supporting structure which, in operation, is subjected to continuous compression and tensile forces as it travels over the ground. Deformation and buckling characteristics of the TNPT are derived from its unique trapezoidal shape which results in an interaction of the structural elements such that the outer hoop is not pulled under the wheel as much as the outer hoop would have been, had the shape of the TNPT been rectangular. The trapezoidal shape provides the TNPT with improved "handling" characteristics in hard turns without sacrificing a "ride" which is surprisingly similar to that of a conventional pneumatic tire.

Filed: 1990-04-10
Abstract: L'invention a pour objet une lamelle de store, notamment de type vertical, comprenant deux pièces minces et  transparentes,  conçues  pour pouvoir venir  se  fixer l'une contre  l'autre par un  système de type à fermoir prévu le long de leurs arêtes longitudinales opposées pour ainsi former les faces avant et arrière de la lamelle.  Le système de type à fermoir utilisé est lui-même conçu pour permettre d'intercaler une bande de papier ou de tissu décoratif entre  les  deux pièces minces préalablement à leur fixation.  La lamelle ainsi obtenue présente un grand intérêt dans la mesure où les deux pièces qui sont de préférene  en  plastique  extrudé  facilitent  grandement l'entretien  de  la  lamelle  tout  en  conservant  l'effet naturel du tissu ou du papier peint.   En outre,  cette structure  permet  avantageusement  à  l'utilisateur  de substituer à volonté n'importe quel autre tissu ou papier décoratif,  de  là  rendant la    structure  extrêmement versatile.

Title: Smoothing filter
Inventor: PERLOFF RONALD S
IPC: H04L29/08
Filed: 1990-08-08
Abstract: Abstract SMOOTHING FILTER    Preamble smoothing for information character transmissions in a data transmission network is accomplished as follows.  First, the smoothing filter identifies the start of a new preamble.  If the start of a new preamble is identified and a previously received preamble has been extended, then the preamble is contracted by deleting an IDLE byte or, if the frame received prior to the initial IDLE byte was a frame fragment, then the information character preceding the initial IDLE byte is deleted. Following the contraction of the preamble, a determination is made as to whether next received byte is an IDLE byte.  If it is not, then the preamble is extended by inserting an IDLE byte and the smoothing filter begins searching for the start of a new preamble.  If it is, then a counter is incremented.  If the counter has not yet reached its preset threshold, then the next byte is checked to determine whether it is an IDLE byte.  If it is, then the counter is again incremented.  This iterative process continues until the counter threshold is reached.  At that point, the smoothing filter again begins searching for the start of a new preamble.

Abstract: Visible Moiré interference is eliminated by alternately shifting the phase of the horizontal sync signal or video signals such that the phase of each video line, and hence the phase of the resulting Moiré interference associated with that video line, is also alternately shifted. The phase of the Moiré interferences are shifted such that persistence of vision in the human eye averages oppositely phased phosphor intensity variations occurring on alternating scan lines and/or vertical fields. When viewed by a user of the CRT, optical cancellation of the Moiré interference patterns results.
