Abstract: Individual information signals encoded with a common block error-correction code are assigned a unique scrambling mask, or signature sequence, taken from a set of scrambling masks having selected correlation properties. The set of scrambling masks is selected such that the correlation between the modulo-2 sum of two masks with any codeword in the block code is a constant magnitude, independent of the mask set and the individual masks being compared. In one embodiment, when any two masks are summed using modulo-2 arithmetic, the Walsh transformation of that sum results in a maximally flat Walsh spectrum. For cellular radio telephone systems using subtractive CDMA demodulation techniques, a two-tier ciphering system ensures security at the cellular system level by using a pseudorandomly generated code key to select one of the scrambling masks common to all of the mobile stations in a particular cell. Also, privacy at the individual mobile subscriber level is ensured by using a pseudorandomly generated ciphering key to encipher individual information signals before the scrambling operation.

IPC: A44B18/00

Abstract: The present invention relates to an improved loop portion of a hook and loop fastening system. The loop portion is a two-layer composite including a compressively resilient backing material and a layer of fibrous loop material. The loop material is placed adjacent the bottom surface of the backing material and then a plurality of the loop fibers are needled or stitched through the backing material to form a plurality of loops which project above the top surface of the backing material. Due to the resilient nature of the backing material, when a hook member is brought into engagement with the loop material, the backing material compresses thereby exposing a greater portion of the individual loops for engagement with the hooks. Once the hooks have been engaged, the backing material expands back to make the exposed portion of the loops smaller. As a result, more individual engagements between hook and loop elements occur and there is less play between the hook members and loop elements thereby yielding a more firmly engaged hook and loop system as evidenced by increased peel strengths when compared to conventionally-backed loop structures. To add increased strength to the structure, the layer of loop material may contain an adhesive to bond the fibers and more firmly anchor the loops so as to lessen the chance of their disengagement during separation of the hook members from the loop members.      Lastly, the adhesive employed may be a pressure-sensitive adhesive to permit the adherence of the loop structure to another substrate such as a diaper outercover.

Abstract: A system, according to the present invention, provides temporary facsimile services to facsimile machines provided in hotel rooms. The system in-cludes an intermediary having a host of direct in-dial telephone numbers which can be selective-ly activated and assigned to any one facsimile machine of a plu-rality of facsimile machines.     The facsimile machines can be selectively authorized by assign-ing thereto for a temporary pe-riod a direct in-dial telephone number from the host of direct in-dial numbers of the interme-diary. The intermediary acti-vates the direct in-dial number whereafter the authorized facsi-mile machine is capable of re-ceiving transmissions sent to the direct in-dial telephone number via the intermediary. The system maintains the direct in-dial number activated until the expiry of the temporary period and thereafter deactivates the direct in-dial number. The direct in-dial number is maintained deactivated for a down period of time whereby any facsimile transmissions sent to the direct in-dial num-ber during the down period of time is not received. In this way, provision is made not to receive any transmissions to the direct in-dial number during any down period whereby the guest is ensured transmissions destined for the particular guest are not re-ceived immediately after his departure from the hotel.

Abstract: A method is described for making a fluidized cracking catalyst having in situ highly dispersed metal traps which comprises (a) impregnating particles of a zeolite catalyst by the incipient wetness technique under sub-atmospheric conditions with a mixture of a tin compound and an antimony compound dissolved in an organic solvent,  (b) stirring the impregnated catalyst in paste form while still under sub-atmospheric conditions,  (c) heating the mixed catalyst in the presence of an oxygen-containing gas until dry, and repeating steps (a),  (b) and (c) above until a desired level of said metals in the metal traps is achieved.  In the incipient wetness technique, an appropriate amount of solvent is added to achieve proper transport of organometallic components, precursors of the metal traps, providing at the same time complete wetness of a given amount of catalyst without forming a layer of liquid on top of the catalyst.  The impregnation procedure is usually repeated at least four times to obtain the desired metal loading.

IPC: F04B43/10
Filed: 1995-06-05
Granted: 1999-08-03
Abstract: A system for pumping liquids that may be subject to solidification in the line, uses a compressed gas as an expulsion medium for the liquid. A compound hose pipeline is used, having a variable volume gas chamber adjacent a compressible transfer passage, both of which extend the length of the line.  The line may comprise an outer hose that provides a gas annulus about a collapsible inner hose, through which inner hose the pumped liquid can flow.  Air or other gas within the annulus operates to expel the liquid by compressing the inner hose.  A compartmented hose embodiment has a separating diaphragm running the length of the hose, dividing the hose into expansible gas and liquid portions.  The system may be self priming, using a source of vacuum to remove the air and expand the volume of the liquid transfer hose portion, to thereby induce filling of the transfer flow portion of the hose or pipeline, followed by an emptying phase, by re-applying air pressure.  A Shrader-type valve or a needle inflator valve in the line outer wall may provide convenient access for inflation air.  The delivery system can use piston or centrifugal type pumps; or a gas compressor can serve as the sole pumping medium.  An immersed intake for use with the system in fresh water can incorporate a fine filter cloth against zebra larvae or other contaminants, which filter is back-flushed at the end of each pumping cycle.  The line, when being operated to serve as a pump may be duplexed, so as to provide more continuous flow.  An inner hose may be used that is normally in a flattened condition, thereby incorporating an initial charge of atmospheric air upon sealing the line ends, while its "memory" assists in dewatering.  A discovered air pressure "bump" when dewatering further contributes to system effectiveness.  The co-extensive hose may be manufactured by co-extrusion, in endless length, thus removing the limitation of having to thread the inner hose within the outer hose.
