Filed: 1993-03-12
Granted: 1997-04-08
Abstract: Arrangements are disclosed for physically partitioning a bus having a well defined architecture as a physical entity, wherein  the  partitioning  is  logically  transparent  to  a computer and devices which communicate through the bus and serves to avoid problems potentially arising because of the scope of actions permitted by the architecture.  A typical bus  architecture  to which  present  arrangements  have relevance  is  that  associated  with  SCSI (Small  Computer System Interface) buses.  The potential problems allowed to occur  architecturally  involve:   (a)  exposures  of  data security/integrity;  (b) excessive signal degradation due to use  of  signal  rates  which  although  allowed  by  the architecture are inappropriate for a particular bus loading environment   also   allowed   by   the   architecture;   (c) restrictions preventing parallel transfer of data between the computer and multiple storage devices; (d) restrictions unduly limiting the number of devices  attachable to one logical bus path (one input-output channel of the computer). The disclosed arrangement partitions the bus into two or more physical entities which to the computer appears as one logical entity.

Abstract: A high-density electronics package (10) that houses a plurality of circuit cards(21, 22, 25, 26), heat sinks (23, 27) and circuit interconnections (33) in a single hous-ing (12). The electronics package (10) uses conical shaped interfaces for locating and locking components, which greatly enhances the serviceability, thermal management and strength of the electronics package (10). Assembly is accomplished by using a selected conical angle on a first heat sink (23) that mates with a matching conical surface (13) on the housing (12). A second heat sink (27) has a conical angle (located in the opposite direction of the conical angle of the first heat sink) that mates with an identical angle on an expandable wedge ring (31) used for positioning purposes. This mounting feature provides automatic heat sink to heat sink axial alignment regardless of tolerances, therefore simplifying assembly and providing intimate contact between the heat sinks (23, 27) and the housing (12), and thus creating a thermal path from the circuit cards (21, 22, 25, 26) to the housing (12). A model of the electronics package (10) has been designed, built and tested, and provides a lightweight, thermally conductive, and structurally sound electronics package (10). The present packageconcept also provides for greater serviceability, easier fabrication, faster assembly, lower cost and increased design latitude. The electronics package (10) is easilyfabricated and requires no special tooling. Assembly of components into the housing (12) is accomplished within minutes and disassembly is equally fast and easy.

Title: Endlessly circulating items transporting apparatus with individual transporting members
Inventor: EBERLE JURG
IPC: B65H29/04
Filed: 1994-07-06
Granted: 2004-11-02
Abstract: The transporting apparatus has a guide which forms a closed loop and in which transporting members circulate. The transporting members are driven at the beginning and end of the effective conveying zone by in each case an independently controllable drive mechanism. Between successive transporting members there are in each case spring elements, which are designed exclusively for the transfer of compressive force. The drive means of the drive mechanisms driving the transporting members are preceded by controlled blocking means, by which the transporting members are prevented from being taken along by the drive means.  As a result it is ensured that each transporting member seizes a printing product, even if there are gaps in the printing products as they are fed to the transporting members, the printing products preferably being fed in imbricated formation. At the delivery point, the delivery of printing products may also be delayed by one or more cycles without stopping the drive means. The spring elements allow a differing number of transporting members to be located between the drive mechanisms.
