Abstract: Hardsided luggage cases have used thermoformed shells of generally tray-like shape. The thermoforming process usually includes the step of vacuum forming. This vacuum forming inherently causes the corner regions at the intersection of the main face and side faces of the tray-like shells to be of a thinner material than the rest of the case, leading to mechanical failure when the luggage case is abused during use. The outer face of the shell is also subject to scratching and abrasion.      The disclosed process (Fig. 5) forms a thermoformable preform (11) by pressure laminating a layer of cloth fabric (44) to one face of the thermoplastic substrate (42), preferably as the substrate is extruded and while still hot from the extrusion process. This fabric/thermoplastic laminated preform (11) can be easily processed in a matched mold press (64). The fabric (44) should be of a non-stretch type. This non-stretch characteristic, together with its intimate bonding to the thermoplastic substrate (42), prevents the substrate from thinning in the corner regions. Indeed, because the intimately bonded fabric (44) drags or pulls the substrate (42) from a number of directions as the corner regions are formed, the thermoplastic substrate (42) accumulates and actually thickens in the corner regions, leading to a shell (12) which is remarkably durable and aesthetically pleasing.

Title: Telecommunications service provision equipment transfer
Inventor: RUEL BERNARD GEORGE
IPC: H04M3/58
Filed: 1992-10-27
Granted: 1996-11-19
Abstract: This invention relates to arrangements for simplifying the transfer of a source of telecommunications signals, such as a telecommunications customer lineor telecommunications trunk, from a first port of a switching system to a second port of that same switching system. Such a transfer requires a transfer of a connection in the outside plant, usually in a manhole, and establishment of a connection from the outside plant to the second port, usually in a distributing frame of the switching system. Translation data is stored for the second port to indicate availability of the second port for assignment to a customer, and, in one embodiment of the invention, to identify the customer to be connected to that second port. In accordance with that embodiment of the invention, the customer line to the first port is tested in the manhole to verify the identity of that customer; the line to the second port is tested to see if the translation data for that second port comprises the same customer identification. If so, a request to assign the translation data for that customer to the second port is then transmitted from the manhole. In response to an acknowledgment that the translation data has been so assigned, the customer's line is transferred to the second port. Advantageously, the translation data can be stored and a connection to the second port can be established ahead of time in the switching system, and the transfer of the line can be carried out by one individual in themanhole without requiring the cooperation of other craft in the switching system.

Abstract: A time-division multiplex switch (100) switches a hierarchy of data rates. It sets up higher-rate connections not as a plurality of individual lowest-rate connections but as one or more time slots in each one of a plurality of sequential frames (40, 50) that correspond to that higher rate in each superframe (30). A time-slot-interchange switching element (131, 141) of the switch utilizes a plurality of physically orlogically distinct double-buffered data memories (301,302,303) each corresponding to a different one of the superframe and different-size ones of the frames. Reading and writing of each of the data memories' buffers alternates with the corresponding one of the superframe and different-size frames; reading of a data memory's buffer immediately follows writing of that buffer. Information from all incoming time slots is written into each one of the data memories, but only information corresponding to the data rate of an individual data memory's corresponding frame size is read from that data memory into outgoing time slots. A control memory (305) maps memory locations of the data memories to output time slots. A corresponding control architecture in a switching element (1700) of a time-multiplexed switch (120) uses a control memory (1701) that maps input ports to time slots of an output port.
