Patent EP-0297895-A3 (EP)
IPC: G06F15/16
Filed: 1988-06-30
Abstract: In a multiprocessor data processing unit, a data 
element in the main memory unit, that has system wide 
significance, can have a requirement that this data 
element be altered in a controlled manner. Because 
other data processing units can have access to this 
data element, the alteration of the data element must 
be synchronized so the other data processing units 
are not in the process of altering the same data 
element simultaneously. The present invention 
includes an instruction that acquires access to an 
interlock signal in the main memory unit and 
initiates an interlock in the main memory unit, 
thereby excluding other data processing units from 
gaining access to the interlock signal 
simultaneously. The instruction causes the data 
element related to the interlock signal to be 
transferred to the data processing unit where the 
data element is saved, can be entered in mask 
apparatus and then have a quantity added thereto. The 
altered data element is returned to the main memory 
unit location and the main memory interlock signal is 
released, thereby completing the instruction.
Patent EP-0327767-A3 (EP)
Title: Programmable comparator output filter
IPC: H03K5/1254
Filed: 1988-12-23
Abstract: A programmable counter or timer (2) is preloaded with 
a value that serves to discriminate between meaningful 
transitions and spurious ones, and an output latch (10) is 
initialized so that the value it contains is equal to 
the initial value of a comparator output. The binary 
output of the comparator is then continuously compared 
with the content of the output latch (10). If the two 
values become unequal, indicating a change in the 
state of the comparator output, the timer or counter (2) 
is enabled to start timing or counting. If the change 
in the comparator output lasts long enough to qualify 
the transition as meaningful, the timer/counter (2) times 
out clocking the new comparator output condition into 
the output latch (10).
Patent EP-0324388-A3 (EP)
Title: Speed control method and circuit of a rotor
IPC: H02P23/16
Filed: 1989-01-07
Abstract: A method and device for controlling the speed of a rotor. Tachogenerators, by means of which the speed of the rotor can be determined, are used for the electronic regulation of drives. The regulation accuracy of known methods is limited by the mechanical tolerance of the tachogenerator elements. A correction value is obtained according to the invention to compensate for the tolerances, in that the motor driving the rotor is initially accelerated to its nominal speed, time intervals between successive pulses are then determined, as well as the total time for one revolution, the number of pulses occurring during one revolution being used to determine an even time pattern, and the desired correction values then being determined from the deviations of the pulses from the time pattern. The invention can be used for motors in which the motor is required to carry out an accurate sequence of acceleration and braking processes as well as precisely maintaining a nominal speed. Applications are motors for digital or analog signal recording units.

Title: A component system for the construction of ground-bearing stairways, platforms, terraces, and the like
IPC: E02D17/20
Filed: 1989-04-05
Abstract: The invention relates to a prefabricated concrete component system for forming ground-bearing stairways, platforms, terraces and analogous structures of one or more layers. It is the object of the invention to be able to construct, from a few basic components, a durable and safe ground-bearing structure of the desired shape. Such a component system comprises at least three different basic components (1, 2, and 3), which are used together or separately and which are slab components provided with upright supports. The basic components of the component system according to the invention are so designed that one or two adjacent slab components in the same constructional layer form at least two support and fastening surfaces for the next higher slab component. Thus a sturdy and safe structure is obtained. The shape of the components enables them to be cast in a single-part casting mold, from which the component will detach owing to beveled surfaces. The system also includes ramp components, edge components provided with edges, and corner components.

Title: Network topology control method and apparatus
IPC: H04L12/24
Filed: 1989-05-04
Abstract: A method and apparatus for controlling the topology of a 
local area network (LAN) configured as a ring of trees. The 
stations comprising the LAN are limited to single access 
stations (SAS), dual access stations (DAS), wire concentrators 
(WC), and DAS/WC combination stations. The topology control 
requires the exchange of connection type information only 
between immediately adjacent stations. The resulting simplicity 
in the information exchange requirements allows validation and 
rejection of invalid connections or reconfiguration of the 
network topology to be implemented as low as the Physical layer 
of the ISO model.

opposed ends of the body (101) for simultaneous axial 
displacement in opposed senses. Application of the 
invented thermoscopic unit to mixing valves (Figure 6),

Title: Arithmetic element controller
IPC: G06F12/02
Filed: 1990-01-25
Abstract: An arithmetic element controller (17) which provides 
for memory address generation for three independent memories 
of a signal processor (10) and for direct memory access from 
external devices by way of an interface (11). The arithmetic 
element controller (17) comprises a first address generator 
(170) which includes a general purpose address generator circuit 
(171) and three separate address generator circuits (172, 
174, 175) which generate memory addresses for data store, 
control store and micro store memories (13, 15, 18), respect­
ively. A second address generator (176) comprises two address 
generator circuits which comprise memory address logic that 
generates memory addresses that permit direct memory addressing 
of the control store and data store memories by way of the 
interface. A memory access controller (178) is coupled to 
the two address generators (170, 176) to control access to 
the respective data store and control store memories (13, 15) 
by the respective address generators. The memory access 
controller (178) comprises arbitration logic (180, 184) which 
arbitrates between requests for data store memory access and 
control store memory access. The second address generator 
(176) comprises a cache memory (190) which stores sets of 
control parameters provided by the control store memory (15), 
which control parameters comprise segment, offset bias and 
word count data. An adder (198), which adds the offset and 
segment parameters to generate a data store memory address, 
and decrementing logic (196) utilizes the count parameter to 
determine the number of words to transfer to the data store 
memory. A second adder (194) combines the bias and offset 
parameters to provide a new offset which is stored in the 
cache memory (190).

Title: A technique for contracting element marks in a structured document
IPC: G06F40/143
Filed: 1990-02-02
Abstract: A method for hierarchically expanding and contracting 
element marks in a structured document. The structured 
document is hierarchically organized, such as documents 
written in Standardized General Markup Language 
(SGML). An element consists of a begin tag and its 
associated content, and may optionally include an end 
tag. The editor can mark an element, to produce an 
element mark, to indicate its selection for document 
processing operations such as moving, copying or 
deleting the content of the element mark. The element 
mark can be hierarchically contracted to lower-level 
element marks by invoking the contract code as appro­
priate. The method also can be used to adjust a 
stream mark to an element mark.
