Title: Method for conferencing a phone call and terminal displayed information associated with it
IPC: H04M3/42
Filed: 1989-11-21
Abstract: This invention describes a method of sharing the call and 
the data terminal information associated with the call 
with a plurality of phone extensions (refer to 4,6 in 
fig.1) and their associated data terminals (5,7 in fig.1). 
This capability facilitates shared access to information. 
A plurality of Computerized Branch Exchanges (CBX) are 
joined via a network means to facilitate the transfer of 
the call and pass a host program running on a host 3 the 
phone source extension and the destination extension for 
the transfer. The host program looks up the source and 
destination extensions in a phone to terminal file and 
determines the network address of the data terminals 
involved and transfers the appropriate host application 
terminal display to invoke a transfer of display informa­
tion to the participants in the conference call either 
automatically or under the control of parties to the 
conversation. The host application sends the data termi­
nal information to the destination data terminal displays 
in conjunction with the transferred phone calls.
Patent EP-0369949-A3 (EP)
IPC: B23H1/02
Filed: 1989-11-15
Abstract: A power supply for an electroerosion machine having a 
switching element (TR1) which controls the machining current in the 
gap (G). The value of the current is compared with a predetermined 
voltage (VR1) and the signal generated based on this comparation is 
provided to a logic gate, advantageously an "AND" gate (A1), whose 
output signal is applied to the control electrode of the 
switching element (TR1). The power supply surpresses any arcing 
tendency during gap short circuit conditions and increases the 
total current through the gap even when gap voltage is low in 
order to maintain a high machining rate. Electrode consumption 
is reduced by using a generally step-type current waveform 
signal. Machining current during the discharge period may be 
controlled to more closely approximate a square wave so that 
shifting to a faster machining rate can be easily accomplished by 
accepting some sacrifice in electrode consuption. Preferably, 
two or more switching and gating devices are used to permit gap 
current to flow intermittently during the entire discharge 
period.

Title: Method for controlling and regulating an automotive engine
IPC: F02D41/14
Filed: 1989-03-16
Abstract: A method in which an output signal (sn) is calculated in a computing device as a function of operating variable signals such as the speed, accelerator pedal position, engine temperature, etc. and this output signal is used to control an electro-mechanical control element for the quantity of fuel and/or air, for example the injection pump of a diesel engine, the P, I and D components of a speed control signal (sn) being determined separately and then added. In this method the D component of the speed control signal (sn) is hyperbolically weighted as a function of the engine speed (n), provision expediently being made for the mean engine speeds (nist, n'ist) to be determined successively at time intervals (T2) proportional to the engine speed, the formation of the difference between two such successive speed values and multiplication of this difference by a constant factor. <IMAGE>

Title: Sales counter
IPC: A47F13/00
Filed: 1990-01-18
Abstract: The invention relates to a sales counter, in which the removal of sheet-like materials, for example wrapping paper, is intended to be made more convenient and easier for the sales personnel. In contrast to the prior art according to German Utility Model 8,127,837, in the invention tubular containers (7) are used to accommodate piles (5) of sheets, the inside circumference of which containers is substantially greater but their inside width is smaller than the length of the individual sheet edge (10). It is thus achieved that the pile (5) of sheets standing on its edges (10) in the tubular container is forced into a curved shape which increases the inherent rigidity of the individual sheet and the mutual frictional forces of the sheets are reduced so that their removal is substantially facilitated. <IMAGE>

Filed: 1991-03-13
Abstract: 2.1 Using a decentralised control processor which is responsible for several junction lines, transmitting and receiving processes for audio frequencies are to be controlled in such an manner that different types of audio frequencies can be transmitted and received individually for each junction line. In addition, the prerequisites are to be created for providing for individual adaptation of the transmitting and receiving levels. 2.2 The decentralised control processor is connected to a digital signal processor which is connected to at least one junction line via transformer circuits. The digital signal processor receives from the control processor adjusting instructions which contain parameters which characterise the signals or signal sequences to be transmitted or to be received in each case. These are used for forming digital generators for transmitting and digital filters for receiving within the digital signal processor. Adjusting instructions can be used for selecting a junction line when the control processor and the digital signal processor is responsible for several junction lines. The signals to be transmitted and to be received in each case are in each case determined in dependence on the state of connection of the relevant junction line, determined by the control processor. 2.3 Using this circuit arrangement, several junction lines can be served by in each case one decentralised control processor and one digital signal processor and the audio frequencies which are to be transmitted and received can be selected for each individual junction line. <IMAGE>

Inventor: MENDELSON RICHARD N
IPC: H04N21/2368
Filed: 1995-07-20
Abstract: A data handling arrangement for a computer system, with particular
application to multimedia systems, allows device adapters (control units)
attached to the system to autonomously (without interrupting the system
processor) control processing of a data stream of arbitrary length
through memory buffers which are smaller than the stream. In this (stream
processing) operation, data constituting the data stream flows through
devices controlled by the adapter in succession, and is held in shared
memory buffers as it passes between devices. The adapters are prepared
for the stream processing operation by a system processor, indicate their
preparation status to the processor, receive an initiating signal from
the processor, and then proceed to direct the operation to completion
without further assistance from the processor. In the operation, the
adapters coordinate usage of the memory buffers by respective devices.
Coordination is accomplished using a notification signalling protocol
defined during preparation of the adapters. For notifying each other of
buffer events (filling, emptying, etc.), the adapters use a peer
communication feature of a system channel which connects the adapters and
devices to the system processor and memory. This feature permits one
adapter to directly communicate "notification" information to another
control unit without involving the system processor. Information
furnished to the adapters during their preparation includes descriptors
defining the memory buffers and the notification protocol. It also may
include descriptors enabling a control unit to synchronize the processing
of data in a stream with events external to the stream; e.g. an external
timer function or events associated with the processing of another data
stream. Thus, for instance, video and audio components of a live motion
picture presentation could be synchronized. The controlling functions
affecting stream processing are isolated from the controlled devices, and
the processing functions performed by each device on data in a stream are
performed independent of the functions performed by any other device
relative to the same stream; thereby simplifying development of new
devices and new processing functions.
