Title: Bandwidth allocation and congestion control scheme for an integrated voice and data network
IPC: H04Q11/04
Filed: 1989-11-28
Abstract: An integrated voice and data network includes a multiplexer 
arranged with a voice queue for storing voice packets and a data queue for 
storing data packets. Voice packets are transmitted for a predetermined 
interval T1. Data packets are transmitted for a predetermined interval T2. 
The predetermined intervals T1 and T2 may be of different durations. A 
separate signaling queue can be provided for storing received signaling 
messages. If a signaling message is moved into the separate signaling queue 
during either interval T1 and T2, that interval is suspended and the 
transmission of voice or data packets is interrupted until the entire 
signaling message is transmitted. Then the interupted voice or data 
transmission is resumed for the remainder of the suspended interval T1 or 
T2. As an alternative, signaling messages can be transmitted during 
predetermined intervals between the intervals T1 and T2. Block dropping 
of low order voice bits also is described for reducing congestion at the node. 
The multiplexer guarantees a certain minimum bandwidth for voice traffic 
and data traffic. Concurrently, the multiplexer allows each type of traffic 
to utilize any spare bandwidth momentarily available because it is not being 
utilized by the other type of traffic. Signaling messages are serviced with 
very low delay and zero packet loss.

Title: Tubular rotary furnace with combustion air blown-in radially through the lining
IPC: F23M5/02
Filed: 1990-01-24
Abstract: Tubular rotary furnace specifically designed for equiflow 
or counterflow combustion or solid, semisolid and other 
waste consisting of a cylindrical shell (1) rotating 
around a slightly inclined (2° - 3°) longitudinal (X-X) 
axis with respect to the horizontal plane. The furnace 
lining is consisting of hollow quoin-shaped refractory 
solid (2) or hollow (3) bricks, of which the latter are 
creating anular chambers (14, 15, 16) which by means of 
holes (11) drilled in the shell (1) and valves (12) are 
communicating with external combustion air inlet pipes; 
These hollow bricks (3) feature strongly inclined channels 
(17, 18) through which the air coming from the anular 
chamber (14,15,16) enters the furnace above and below the 
fuel bed . A special distributor (20a, 20b) at the head of 
the furnace permits to blow a proper amount of primary 
air into the various furnaces zones (S1, S2, S3), only 
through the refractory bricks covered by the material to 
be incinerated.  
     An additional dosis of air may be let into the refractory 
bricks (3) lining the furnace zone in which combustion 
gases are collected, thus allowing for proper secondary 
combustion and total dissociation of the waste gases.
Patent EP-0381071-A3 (EP)
IPC: H01L29/732
Filed: 1990-01-26
Abstract: A bipolar transistor and method of making the same is 
disclosed. The transistor has an emitter region (89) which is 
diffused from polysilicon (69e) into the intrinsic base region 
(61), where the polysilicon (69e) is doped with two dopant 
species of different diffusivity. The impurity concentration of 
the higher diffusivity species, for example phosphorous, can be 
selected to define the emitter junction depth, which is 
preferably shallow, while the impurity concentration of the lower 
diffusivity species, for example arsenic, can be selected to 
provide a high conductivity emitter electrode (69e), as well as 
reduce the sensitivity of the emitter electrode (69e) to 
counterdoping from the implantation of the extrinsic base region 
(86). The structure is compatible with BiCMOS processing, as the 
same anneal can be used to diffuse the emitter (89) and the 
source/drains (74, 84) of the MOS transistors, with the emitter 
junction depth optimized via the implant conditions of the higher 
diffusivity species. The emitter electrode (69e) according to 
the invention can also be exposed to the opposite conductivity 
type source/drain implant, with reduced sensitivity to 
counterdoping.

Title: A method of managing unit-of-work identifiers in a distributed transaction processing system
IPC: G06F12/00
Filed: 1991-08-13
Abstract: The system has a plurality of processing nodes (300) which are logically connected to form a tree, Normally, each node (300) automatically increments its present identifier at the end of processing each transaction to derive the next transaction identifier. However, in response to a failure condition which results in a severed tree, the distributed database (304) that now reside in the first and second subtrees that result from the severance are forced to consistent states. The transaction identifier is incremented in each of the nodes (300) of the first subtree. Transaction work in the first subtree then proceeds with the incremented identifier. The second subtree is dismantled. In response to a nonfailure condition which results in a severed tree, the distributed database in the first and second subtrees that result from the nonfailure severance is committed to a permanent state. The transaction identifier in each of the nodes of the first subtree is incremented. Transaction work in the first subtree then proceeds with the incremented identifier. A new transaction identifier is generated and propagated to all nodes of the second subtree. Transaction work in the second subtree then proceeds with the new identifier. <IMAGE>
