Title: Mobile communications
Inventor: MAUGER RAY
IPC: H04W88/16
Filed: 1991-06-12
Abstract: A flexible and equitable PCN/PSTN interconnection strategy between a communications network having mobile subscribers, such as a PCN network, and a PSTN whereby to form a communication system in which multiple tariffs can be applied, the tariff applied being determined by the actual location of the mobile subscriber involved in a call. The PSTN (2, 6, 9, 10) is not given total access to the PCN (1, 5, 8, 11) location registers, rather a PSTN to PCN call is via a PCN gateway (5) which does have access to the location registers. The gateway (5) accepts zonal calls with which are associated one tariff (zonal interconnect 4) but for, for example, local or interzonal calls, it provides drop back messages to the PSTN to arrange for appropriate rerouting to other gateways (1, 8) of the PCN which have different tariffs associated therewith (local interconnect 3, interzonal interconnect 7) (Fig 2).

Inventor: SZAZDI JOHN S JR
IPC: B02C23/38
Filed: 1991-07-30
Abstract: Disclosed is an apparatus and a method for the comminution of brittle material in a roll crusher.          The method comprises the steps of introducing fresh material feed into a roll crusher  which is divided into two distinct feed inlet zones which are at least one  initial  feed  inlet  zone for  said fresh  feed material and at least one secondary feed inlet zone for feed which has been stressed at least once by said roll crusher.  Each initial feed inlet zone and each secondary  feed  inlet  zone  directs  feed  into, respectively, a corresponding initial feed crushing zone  and  secondary  feed  crushing  zone.   In  the invention, fresh feed material is introduced into the roll crusher only in the initial feed inlet zone(s) whereby it is stressed at pressures sufficient high to cause the formation of at least some agglomerates.          The product thus  formed  is  recirculated,  without causing  any  substantial  disintegration  of  the agglomerates,  into  the  roll  crusher  through  the secondary feed  inlet  zone whereby  it  is  further stressed  at  pressures  sufficient to  cause  the formation of at least some agglomerates.

Abstract: LAUNDRY EVALUATION PIECE INCLUDING BLEACHING ACTIVITY INDICATOR SWATCH                     ABSTRACT OF THE DISCLOSURE    The effect of chlorine concentration in laundry solutions on the life of the laundered fabrics is signalled by a chlorine concentration indicator swatch, in which contrastingly hued dyes, including one whose chlorine resistance is measurably stronger than the other, are combined to dye fabric test swatches an initial color.  Including such fabric test swatches in chlorine-containing laundry solutions causes visually discernable changes in the hues of the swatches as the bleaching action progressively subtracts those dyes of lesser resistance.  Chlorine concentration which, if excessive, seriously impairs laundered fabrics, may be determined by visually inspecting the swatches.

Title: Paging system with local channel lists
Inventor: KING RANDOLPH E
IPC: H04W88/02
Filed: 1990-06-07
Abstract: A paging receiver is provided a list of alternative paging channels to which  it can tune if the paging channel presently being received becomes unreliable. This list, and other lists used by paging receivers in other geographical areas, are disseminated by linked paging transmitters that broadcast identical paging signals throughout a large geographical area. When a paging receiver finds a channel carrying paging data it identifies which of the plurality of transmitted lists is appropriate for its use by finding the list that references the channel to which the receiver is presently tune d. The channels referenced in the identified list are then stored in a memory and may be tuned if the existing paging signal is lost. Data is desirably transmitted with the local channel lists to permit each paging receiver to locate the list relevant to its geographic al area without examining each of the transmitted lists.
