Patent EP-0345922-A3 (EP)
IPC: H03M1/00
Filed: 1989-03-15
Abstract: A digital-to-analog converter (DAC) ladder segment is 
disclosed in which diode networks are introduced into the 
ladder step circuits. Each diode network includes a control 
diode which controls the flow of current through the network 
in accordance with a signal from an associated actuating 
circuit, which in turn is controlled by an input digital 
signal. In one embodiment, the control diodes are connected 
in series with resistors, with the diodes and resistors scaled 
so that their respective bit circuits conduct desired current 
levels. In another embodiment, the control diodes have equal 
scalings and are connected in series with respective resistors 
and second diodes which are scaled so that their step circuits 
conduct the desired currents. In a third embodiment, current 
sources are provided which supply currents to the second 
diodes in amounts that permit the second diode and the resis­
tors for the various step circuits to have substantially equal 
scalings. The different embodiments can also be combined to 
obtain the advantages of each. Current errors associated with 
metallization resistances are substantially reduced by imple­
menting the control diodes as bipolar transistors, having 
their bases and collectors connected together at a location 
remote from the diodes by means of metallic base and collector 
leads that are electrically isolated from each other in the 
vicinity of the diodes.

Title: Process and boiler for combined heating of a building and a domestic hot water accumulator.
Inventor: KREMER ROBERT
IPC: F24H9/00
Filed: 1994-02-18
Abstract: In order to increase the thermal efficiency of a three-pass boiler which is used for combined heating of a domestic hot water accumulator and a building heating system, it is proposed to surround the second and third pass with a first water space (5) having a comparatively low water volume. The first water space (5) is at least partly separated from a second water space (7) by a boundary surface (8). Whereas the heating of the water in the first water space (5) via heat-exchanger surfaces takes place directly by means of the hot waste gases, the second water space (7) is heated via the boundary surface (8) indirectly and by means of gravity circulation. The first water space serves solely to heat the accumulator, whereas the second water space has the connections for the heating-system circuit. The connection piece (9) for the flow of the accumulator circuit is situated at the highest point of the boiler and the return connection (10) at the lowest point of the first water space (5). At the same time, the water spaces (5, 7) are interconnected in this region, so that a normal gravity-flow operation of the boiler is possible. On the other hand, when a feed pump for the accumulator circuit is switched on, the gravity flow is cut off. <IMAGE>

Title: Trellis coded qam using punctured convolutional codes.
Inventor: HOW STEPHEN K
IPC: H03M13/00
Filed: 1994-05-03
Abstract: Punctured binary convolutional codes are used in a trellis coded modulation scheme to achieve spectral efficiencies as high as those of multi-dimensional codes, using simple hardware. A base rate 1/2 binary convolutional code is punctured to rate n/k. The output of the punctured encoder 18 is mapped to a four-way partition (60, 62, 64, 66; 120, 122, 124, 126) of a 2<N> point two-dimensional QAM constellation. The four-way partition consists of a two-way partition in both the I and Q dimensions. The two-way partitions of each dimension are used to transmit the two level output of the rate n/k binary convolutional coder. (N-2) "uncoded" bits (24) are transmitted by selecting the unique constellation point in a partition group. The code has an average throughput of (N-2)+2n/k bits per symbol. The invention is also applicable to trellis coded amplitude modulation schemes based on 2<N> possible amplitude levels provided along a one-dimensional constellation. <IMAGE>

Title: Method for melting glass in a tank furnace and tank furnace used therefor.
Inventor: SORG HELMUT DIPL-ING
IPC: C03B5/235
Filed: 1994-08-06
Abstract: In a furnace for melting glass, a preheating zone, a melting zone, a refining zone with a refining bank raised above the rest of the floor and an homogenizing zone, are arranged lengthwise behind one another between the charging end for the glass raw materials and a throat for the molten glass. The furnace chamber formed between two end walls is split up by dividing walls with the exception of flow paths for the glass and waste gases. The melting zone, the refining zone, several burners and the homogenizing zone have a common combustion chamber in the superstructure. A first flow path "L1" for the glass is defined between the inside face of the first end wall and the vertical center line (E) of the final dividing wall in front of the refining zone, and a second flow path "L2" is defined in the combustion chamber between the vertical center line (E) and the inside face of the second end wall. The ratio of the length "L2" to the total length ("L1"+"L2") is chosen to be at least 0.5, preferably at least 0.53. The lengths "L1" and "L2" are the horizontal components of the corresponding flow paths. The greater part of the heating energy is supplied to the glass melt in front of the refining bank in the melting zone, and the heating and melting energy for the raw materials is applied from above from the waste gases, and from below solely from the current in the glass melt which extends as far as the charging end. Therefore, the charging end of the melter does not require any electrical heating, at least during continuous operation.

Title: Ringdown and ringback signalling for a computer-based multifunction personal communications system.
Inventor: LI PING
IPC: H04M1/247
Filed: 1994-06-29
Abstract: The voice over data component of a personal communications system enables the operator to simultaneously transmit voice and data communication to a remote site. This voice over data function dynamically allocates data bandwidth over the telephone line depending on the demands of the voice grade digitized signal. The user may enter voice over data mode from a data transfer mode by lifting the handset of the telephone connected to the modem. The off-hook condition is sensed and software sends a supervisory packet to the remote site to invoke voice-over-data mode. The remote telephone will simulate a ring to alert the remote user, and the local telephone will simulate a ringback to inform the caller that the remote unit is responding.

Abstract: A method of determining which of plural
protocols are active on a computerized local area
network. Each of plural frame types are registered
with a link support layer (LSL)(187) which monitors
network communications for broadcast frame packets.
A frame packet which matches a first one of the
frame types is provided from LSL, and protocol
header information in the received frame packet is
decoded so as to determine protocol used in the
frame packet. The first frame type is de-registered
from LSL, a first protocol stack corresponding to
the determined protocol is initialized using the
first frame type, the first protocol stack is
loaded, and the first protocol stack registers
itself with LSL so that the first protocol stack
receives future frame packets which match the first
frame type. Thereafter, if LSL encounters any other
frame types, the above processing is repeated so as
to load and register any other needed protocol
stacks.
