Abstract: Local telephone number portability is effected with automatic changeover of local telephone service for a subscriber station from an incumbent local exchange carrier (ILEC) loop to a competing local exchange carrier (CLEC) loop. A relay device that may be placed remotely at the subscriber's location automatically effects a change in physical connection of the subscriber's line in response to an incoming call routed to the customer premises via the CLEC switching facility. The physical presence of a technician thus is not required at the customer premises at the time changeover of service is made. Delay in the capability of receiving incoming calls at the customer premises during changeover of service is avoided by ensuring that physical reconnection is made only after the appropriate updated routing information has been made to the PSTN network. If a call via the old subscriber service is in progress, automatic reconnection is inhibited until an off-hook condition is realized.

Abstract: A conductive line in a thin-film structure such as an AMLCD array includes molybdenum and chromium so that it can be processed in a manner similar to chromium but has a greater conductivity than chromium due to the molybdenum. The conductive line can be produced by physical vapor deposition of a layer of a molybdenum-chromium (MoCr) alloy, which can then be masked and etched using photolithographic techniques in a manner similar to chromium. Proportions between 15 and 85 atomic percent of molybdenum can be processed more easily than pure molybdenum and are more conductive than pure chromium. Lines with between 40 and 60 atomic percent molybdenum can be used with a margin of error. To produce a tapered conductive line, sublayers of MoCr alloys with different etch rates can be produced and etched.

Abstract: A feature in a thin-film structure such as an AMLCD array has an edge with a tapered sidewall profile, reducing step coverage problems. The feature can be produced by producing a layer in which local etch rates vary in the thickness direction of the layer. The layer can then be etched to produce the feature with the tapered sidewall profile. The layer can be produced by physical vapor deposition. The layer can, for example, includes sublayers with different etch rates, either due to different atomic proportions of constituents or due to different etchants. Or local etch rates can vary continuously as a result of changing deposition conditions. Differences in etch rates or differences in etchant mixtures can be used to obtain a desired angle of elevation.

Abstract: A thin-film structure on an insulating substrate includes an array of binary control units with an area of at least 90 cm.sup.2 and a density of at least 60 binary control units per cm. One implementation has an area of approximately 510 cm.sup.2, a diagonal of approximately 33 cm, and a total of approximately 6.3 million binary control units. Each binary control unit has a lead for receiving a unit drive signal, to which it responds by causing presentation of a segment of images presented by the array. Each binary control unit can present a segment with either a first color having a maximum intensity or a second color having a minimum intensity. Each binary control unit's unit drive signal causes the binary control unit to present its first and second colors. The substrate can be glass. Each binary control unit can include an amorphous silicon thin-film transistor (TFT) and a storage capacitor. Each binary control unit can be square.

Abstract: An inexpensive rack which is mounted on the roof of an automobile. Other objects are then mounted on the rack for transport with the automobile. The rack is an elongate lamination including a pair of opposed soft foamed outer layers, and an inner reinforcing layer therebetween. The reinforcing layer extends outwardly of the soft layers defining end tabular portions which are sandwiched between the car roof and the opposing doors to secure the rack to the vehicle. In a preferred embodiment, a pair of racks are mounted in spaced relation across the automobile roof. An object positioned thereon is secured to the automobile by conventional means of rope, straps, or the like.

Abstract: A food product resembling either solid or liquid margarine which resists burning or blackening when heated. The product contains between about 0.20 and 0.63% by weight protein from complete milk solids or milk whey with less than about 2000 parts per million by weight of reducing sugar in the final product.

Abstract: A flavored neutral oleaginous food is prepared by blending together a neural oleaginous food with a minor amount of (i) alpha carboxy butyric, isobutyric, valeric, isovaleric, caproic, capric or caprylic acid and/or (ii) one or more of the ethyl or butyl esters of those alpha carboxy acids.
