Patent EP-0236277-A3 (EP)
IPC: G05D1/02
Filed: 1987-01-28
Abstract: The device comprises two pick-up elements (5, 6), which 
can cooperate independently (9, 10), a transmission line (L₁) 
for control signals, aligned in the direction of movement of a 
conveyor unit (C) so as to be positioned respectively up­
stream (5) and downstream (6) in the direction of movement 
of the conveyor unit (C). The two pick-up elements (5, 6) are 
separated by a distance such that, during traversal of the 
gaps between successive sections of the line, at least one of 
the two pick-up elements (5, 6) is able to receive signals from 
the transmission line (L₁, L₅). A signal treatment circuit 
generates selectively an output control signal corresponding 
either to the single signal received by the two pick-up 
ments (5, 6) or to the control signal (7) received by the pick-up ele 
element (5) in the position upstream relative to the direction 
of movement of the conveyor unit (C) when the pick-up ele­
ments (5, 6) receive different signals.

IPC: H04M11/00
Filed: 1988-01-22
Abstract: In order to access a data base system, a system user 
establishes communication with an interface unit (10) 
associated with the data base system (13,14) by means of 
telephone apparatus (11). Upon being connected with the 
data base system (13,14), the user is presented with a 
predetermined verbal message produced by a digitizing 
speech unit (22) responding to preestablished logic signal 
sequences. In response to this message, the user can 
select from a plurality of verbally presented options by 
an appropriate activity, such as depressing the appropriate 
key on the dialing apparatus of a touch-tone telephone 
apparatus (11). By providing a verbal response from the 
interface unit (10) that is determined by the user response 
to presented options, the system user can communicate with 
the interface unit (10), the verbal responses from the 
interface unit (10) representing an abbreviated menu for 
the system user. As a result of this communication, a 
system user can interrogate and retrieve data from a data 
base without data processing apparatus. The retrieved 
data can be provided to the user by speech digitizing 
procedure or can be transmitted to the system user by 
another procedure determined by the interaction between 
the data base system (13,14) and the system user. 
This type of interaction between the system and the 
 
 
system user can permit unsophisticated persons to 
access data bases without operator assistance and 
without the requirement of availability of data 
processing apparatus. When data processing apparatus 
is available, the user can access the system data 
bases by menu-driven interaction with interface unit 
(10) in a conventional manner.

or removal of water at low temperatures under vacuum. 
The method results in the recovery of a dried bioactive 
somatotropin.

Filed: 1988-10-10
Abstract: A Pipeline and Parallel Processing system for generating Surface 
Patches for both Wireframe and Solid/Shaded Models in a Raster Graphics 
Display. The inputs to a Transformation Processor are the parameters for 
the Rational Bezier Surfaces: a 2-dimensional array of control points, 
and weights. The outputs are the coordinates of the corner points and the 
normals (to the surface) of the patches, which make up the surface. The 
system consists of three Pipeline stages: 1. A front-end processor 
fetches the data from memory and feeds the Transformation Processor; 2. 
four Floating Point Processors in Parallel for tessellating the surfaces 
into small patches; and 3. one Floating Point Processor for generating 
normals at the vertices of the small patches. The output is sent to the 
rest of the Graphics System for clipping, mapping, and shading.

Title: Updating pattern-matching networks
IPC: G06F9/44
Filed: 1989-11-10
Abstract: A pattern-matching system, such as of the RETE type, is updated. The 
updating operation is generalised to operate with correct match results 
for generalized RETE networks (ones where join nodes may have either 
predecessor be another join node), and for arbitrary partial update 
state, and uses stop nodes designating how far update operations have 
progressed for particular update tokens (designated suspended tokens) 
at any particular time. The updating operation consists of the follow-­
ing steps: First, all tokens only partially updated through the 
network are shadowed, in that the partial result memories associated 
with the stop nodes are put into the state that exists or existed 
before the suspended tokens arrive at the stop nodes. Then for each 
suspended token, it is pushed to resume nodes connected as RHS (or LHS) 
inputs in a descending order of resume nodes. The descending order is 
determined among sets of resume nodes where one node is reachable from 
the other, either in an upwards or downwards direction. Following one 
token's push to RHS (or LHS) connected resume nodes, that token is 
unshadowed in the stop node's associated result memory, and that token 
is then pushed to resume nodes connected as LHS (or RHS) inputs, in an 
ascending order of resume nodes. Tokens are pushed from alpha top 
nodes when the stop node is in the alpha portion of the RETE network, 
to the suspended portion of the successor nodes of the alpha top node.

Abstract: The method of bending metal sheet sections is carried out with a bending punch and a bending die (27) which has an adjustable base (28). The die holder (26), with an elastic table plate (25) in between, rests on a number of plungers (13, 14), arranged side-by-side, of plunger-cylinder units (12, 13, 14) which can be individually pressure-loaded. Before the bending process, the plunger-cylinder units (12, 13, 14) are loaded with a pressure which is greater than the air-bending force required for the bending. As a result, the said plungers (13, 14) strike a stop (17). After the air bending is complete, the bending force increases and the plungers (13, 14) located in the area of the metal sheet section to be bent are forced back. The metal sheet section is uniformly shaped along the elastic line of the punch edge. Here, the two outermost plunger-cylinder units on the left and right strike stops which compensate for the metal sheet thickness lacking at these locations provided the metal sheet section to be worked is shorter than the length of the die.
