Title: Electrochemical cell for measuring ionic activity in a solution and its method of use
IPC: G01N27/416
Filed: 1989-06-29
Abstract: An electrochemical cell for measuring the activity of one 
or more ionic species such as pNa, pK, pCa, pNH₄, pCl etc. 
consisting of two sensors selective to the actual ionic 
species, one of which is used as the reference electrode 
and the other as the measurement electrode.  
     The two sensors are chosen preferably identical.  
     The electrode used as the reference electrode is brought 
into contact with a solution of known ionic activity and 
an ionic strength which is greater, equal to or 
substantially greater than that of the unknown solution to 
be measured.  
     The measurment electrode is brought into contact with the 
unknown solution to be measured, while a third electrode 
is used purely for instrumental reasons and does not 
participate in the measurement.

Patent EP-0356103-A3 (EP)
Title: Scan-conversion process and processor
IPC: G06T11/40
Filed: 1989-08-15
Abstract: A scan-conversion processor converts a graphic 
primitive defined by its outline to pixel data by storing 
edge data blocks containing the y-coordinates of the 
vertices of each edge, the x-coordinate of the lower vertex, 
and x-coordinate increment data. The edge blocks are linked 
in ascending order of their minimum y-coordinate values into 
edge chains representing consecutive series of upward- or 
downward-inclined edges. Information indicating the edge 
inclination can also be stored in each edge data block, to 
support use of the non-zero-winding algorithm to 
discriminate between the interior and exterior of the 
graphic primitive. Since it requires relatively little 
memory space, the scan-conversion processor, including its 
memory, can be implemented as a single integrated circuit on 
a semiconductor chip.

Title: Method and apparatus for analysis of particles contained in a liquid sample
IPC: G01N15/14
Filed: 1989-09-13
Abstract: Particles contained in a liquid sample (17) are 
analysed by moving the particles along a detection 
passage (12,13) past a detector by means of a liquid 
flow in said passage. To reduce the time required for 
each sample, the sample is delivered at an input 
location (7,8,9) at the upstream end of the detection 
passage by movement of a movable container (2) carrying 
said sample to said input location. Immediately after 
commencement of the delivery of the liquid sample, the 
liquid flow is caused to occur in the detection 
passage.  
     Washing liquid is supplied to the input location 
(7,8,9) by means different from said container which 
carries the sample.

Title: Circuit arrangement for communication exchanges, especially telephone exchanges, with distributed switching groups and central switching arrangements
IPC: H04Q3/60
Filed: 1990-01-16
Abstract: A central processor interrogates concentrators via line trunk groups for temporarily stored data successively in a cyclic sequence. In each of the concentrators, it is monitored whether the time interval between in each case being interrogated and next being interrogated exceeds a predetermined time limit value. When the time limit value is exceeded, the relevant concentrator continuously repeatedly reads the data out of its store and transfers them to the central processor. Concentrators are set up for interworking with the central processor and with line trunk groups of in each case a relatively old and relatively new type of construction. The extent of the data to be transmitted on the basis of being interrogated depends on this. The concentrator stores the type of construction feature. When the time interval is exceeded, the temporarily stored data are transmitted as determined by the type of construction feature stored in each case. <IMAGE>

IPC: G06T11/20
Filed: 1990-03-16
Abstract: Apparatus and method for providing x, y and Z values so as 
to construct figures from unit vectors rotated in three space 
wherein the x, y and z values result from processing construction 
and rotation parameters according to the following relationships:  
ΔX′ = ΔX COS(G z ) +ΔY SIN(G z )  
ΔY′ = -ΔX SIN(G z ) + ΔY COS (G z )  
ΔZ′ = ΔZ  
where,  
ΔX = COS(R z ) COS(R y  + G y )  
ΔY = COS(R z ) SIN(R y  + G y ) - SIN(G x ) - SIN(R z ) COS(G x )  
ΔZ = COS(R z ) SIN(R y  + G y ) + COS(G x ) + SIN(R z ) SIN(G x )  
X = X + ΔX′, Y = Y + ΔY′, Z = Z + ΔZ′  
and,  
R z , and R y , are construction rotation parameters for the Z and Y 
axes, respectively, and G y , G x  and G z  are global rotation 
parameters for the Y, X and Z axes, respectively. As used in a 
graphics display system, the invention provides offset values to 
an apparatus for summing offset values from a specified point. 
An apparatus for providing depth cuing related to the offset 
values may be advantageously included in an alternative 
embodiment for apparatus employing the principles of the 
invention. Processed x, y and z values, together with color 
cuing information may then be stored in a memory prior to 
displaying the figure.

Title: Method of manufacturing molding material containing metal fibers and apparatus therefor
IPC: B21C37/04
Filed: 1990-05-21
Abstract: A method of manufacturing a molding material includes 
the steps of winding a thin metal strip (20) on the peripheral 
surface of a rotary shaft (10) a number of turns with a resin 
material (21) being interposed therebetween, cutting an end 
surface of the metal strip and the resin material 
by a cutting blade (51) while rotating said rotary shaft (10) to 
obtain a mixture of metal fibers and resin fibers (KS), and 
heating the fiber mixture to a temperature at which the 
resin fibers can be softened. In this way, a molding 
material (SS) in which the metal fibers are substantially 
uniformly dispersed in the resin material in a closely 
contacted state can be obtained easily. Furthermore, the 
contents of the metal fibers by volume in the molding 
material can be arbitrarily adjusted by changing the rate at 
which the metal strip and the resin material are wound 
around the rotary shaft.

Title: Intermediary station in a communications transmission link
IPC: H04J3/08
Filed: 1990-06-13
Abstract: In the transmission of digital signals in time-division multiplex via a transmission link with repeater stations at which time slots are either only dropped are also reoccupied, the problem arises of continuing to maintain the information transmission even with an alarm triggered in a repeater station. The invention provides for a bypass circuit (11) via which the repeater station is bypassed when an alarm is triggered in it. If a reoccupation of the time slots is intended, the bypass circuit (11) in this arrangement can send a message to the neighbouring repeater stations and/or the line terminating device for allowing the reallocation of time slots which have not been reoccupied in the repeater station. If the time-division multiplex signal contains a service channel, messages can be sent to the neighbouring repeater stations and follow-up measures initiated via this channel. <IMAGE>
