Title: Variable-angle multiple channel amplitude modulation receiver
Inventor: HERSHBERGER D
IPC: H04H20/49
Filed: 1982-12-06
Granted: 1983-04-09
Abstract: The system includes a modulator for providing a composite modulated signal having a subsonically varying quiescent carrier component. An adaptor separates the composite modulated signal into AF and RF components for application to AF and RF inputs of an AM transmitter. The adaptor includes a device responsive to the composite modulated signal. A device subsonically adjusts the gain of the envelope signal so that its DC component remains fixed. This reduces harmonic distortion resulting from AC coupling of the envelope signal into the AF input of the AM transmitter.

Abstract: Methods and apparatus for exchanging frames between bridges distribute load sharing in a communications network. The communications network is of the kind in which bridges, and related stations and local LANs, e.g. Ethernet LANs and 802 LANs, can be linked by paths in a plurality of sub-networks and wherein the bridges are linked to support a Spanning Tree Protocol (STP) which elects one bridge as a root and then with respect to said root, computes and utilizes one and only one loop-free set of primary paths between all bridges. Remaining paths, i.e. paths other than said STP primary paths, between the bridges are examined as possible sub-network paths for a Distributed Load Sharing (DLS) configuration in which frames exchanged between certain stations can utilize more than the STP one set of primary paths. Certain ones of the remaining paths are selected as DLS paths under certain conditions and frames are routed over a selected DLS path only when those frames meet certain criteria.

Abstract: A shut-off and/or control element for tapping liquid metal melt from a metallurgical vessel has an inner tube (2) secured on the vessel (5) and having at least one opening (14). A front edge (15) of a movable outer tube (3) encircles the inner tube (2). The outer tube (3) can be moved out of a closed position into an open position of the opening (14). In order to avoid the possibility of plugs of metal melt forming in openings (14) of the outer tube (3), the relative position of the opening (14) of the inner tube (2) and of the front edge (15) of the outer tube (3) is configured in such a way that, during the movement of the outer tube (3), the front edge (15) moves beyond the opening (14). Viewed in the direction (13) of the longitudinal axis, the front edge (15) is situated on one side of the opening (14) in the open position and on the opposite side of the opening (14) in the closed position.

Title: Mode transfer method in dual port memory system

Abstract: A read transmission cycle (6) consists of a  read  converting step (RT) and a real time read converting step  (RRT),  which  are carried out to transmit stored data to a SAM port.  Then  a  write transmission cycle (7) is carried out which consists of: a  serial writing step (SW) for storing an external data into the SAM  port; and a write converting step (WT) for transferring the data of  the SAM port to a RAM port. A presumed write converting step (PWT)  is carried out only under a write mode, without carrying out the data transfer through the read transmission cycle  (6)  and  the  write transmission cycle (7). The  method  simplifies  the  checking  of defective state of memory device during the manufacturing process.
