Title: Digital-information transmission method for communication-switching systems
IPC: H04L12/54
Filed: 1989-02-11
Abstract: On a serial bus configured in ring structure, to which several series-connected transmitting and receiving stations and a central ring control are connected, the possibility is to be provided to switch through information items of more than two different switching categories on the same transmission medium. In this connection, so-called broadband channels are formed which can either be reserved for a connection-related or line-related synchronous channel allocation or are made available for the asynchronous switching of data packaged in variable-length packets. Given these prerequisites, the possibility is to be provided to switch through packets of a third switching category. The information of the third switching category, packaged in packets of uniform length is also asynchronously switched through in that some of the broadband channels reserved for the synchronous type of switching through but not yet used are occupied for this purpose. In this connection, all stations transmitting and receiving the third switching category are informed by transmitting signalling data as to the broadband channels in which information items of this third switching category can be transmitted and received. The transmissions of the information items packaged in packets of uniform length in accordance with the scheme of the third switching category over the same transmission medium are made possible without having to carry out modifications in a standard defined for the mixed transmission of synchronous and asynchronous information items. <IMAGE>

Patent EP-0337495-A3 (EP)
IPC: F16H59/22
Filed: 1989-04-17
Abstract: During non-shift modes of transmission 
operation, the line pressure is controlled according to 
a basic line pressure control schedule (14). Upon a shift 
being initiated it is determined if the shift is being 
conducted under power ON or power OFF conditions by 
sensing the status of a idle switch associated with the 
engine throttle valve. In the case of a power ON shift, 
first and second maps which are record solenoid valve 
duty cycle in terms of engine load and vehicle speed are 
read out of memory and sequentially used one after the 
other to control the line pressure during the shifting. 
In the case of a power OFF shift, tables recorded in 
terms of duty cycle and vehicle speed are fetched and 
used one after the other. The changing from the first 
map or table to the second one is determined by 
comparing the rotational speed ratio which exists 
between the input and output shafts (12, 13) of the transmission 
with a shift solenoid control schedule (14) which relates to 
the type of shift and which is being conducted and which 
is recorded in terms of gear ratio and engine load (e.g. 
throttle opening).

Patent EP-0372226-A3 (EP)
IPC: G01R31/3183
Filed: 1989-11-03
Abstract: Phase enhancement means are employed in conjunction 
with linear feedback shift registers to generate 
sequences of binary pattern vectors which are much more 
structurally independent of one another thus enabling 
more thorough and comprehensive testing of integrated 
circuit systems. More particularly, the present 
invention employs a plurality of exclusive-OR gates in 
an array of one gate per shift register output cell to 
generate the desired uncorrelated pattern strings. 
This facilitates testing of integrated circuit devices 
and systems and is particularly useful for built-in 
test situations for very large scale integrated 
circuits which employ pseudorandom test methods.

voltage supplied from the power source (8). The dc pulse 
voltage thus formed is applied across the electrodes (3a′, 
3b′) to cause the lamp to be lit. The pulse frequency of the 
pulse voltage and the enclosed gas pressure are determined 
depending upon the rare gas employed, and particularly where 
dc rectangular pulses are used, the duty ratio is also deter­
mined depending upon the rare gas employed.

IPC: H04N1/23
Filed: 1989-04-27
Abstract: A dot generator system is provided wherein 
an LED microchip array having staggered rows of LED's 
imaged onto the surface of a rotating exposure drum 
is controlled to create a multiple exposure beam 
microdot image on the drum surface in a microdot line 
by microdot line and scanline by scanline exposure 
scan. Picture values are compared to microdot 
density values recalled from a dot density profile 
array using address values incremented with microdot, 
flyback and scanline increment values in order to 
produce exposure data bits indicating whether each 
active LED on the array is to be turned on. Exposure 
data bits are accumulated into an exposure data word 
equal in length to the number of active LED's on the 
LED array and stagger compensation time delays are 
applied to exposure bits corresponding to the second 
and subsequent staggered LED rows to create a timed 
microdot line exposure on the drum surface.

Title: Method for manufacturing lithographic printing plates
IPC: G03F7/40
Filed: 1989-06-16
Abstract: The method comprises developing a presensitized plate for use in making 
lithographic printing plates imagewise expopsed to light with an 
alkaline developer utilizing an automatic developing machine and then 
treating the developed presensitized plate with a finisher, wherein an 
initial pH of the finisher ranges from 2 to 8 and a pH of the 
finisher is controlled during running in proportion to concentration 
of the developer included in the finisher. 
A formula relating pH to concentration is disclosed. 
The method makes it 
possible to prevent the formation of gel-like insoluble matters in 
the bath for treatment with the finisher due to the presence of the 
developer carried over from a developing bath and to stably process a 
large amount of lithographic printing plates over a long time period.
Patent EP-0358366-A3 (EP)
Title: Electrostatic capacity-type displacement sensor
IPC: B62D15/02
Filed: 1989-08-21
Abstract: A dielectric capacity-type displacement sensor is 
provided for measuring relative displacement between a 
cylindrical member and a rod member. The dielectric 
capacity displacement sensor includes a conductive 
cylinder arranged coaxially to the cylindrical member and a rod 
member for movement within the cylindrical member. The 
cylindrical member is filled with gas such as air or an N₂ gas 
as a dielectric medium independent of variations in temperature 
and has an inner surface facing the outer periphery of the rod 
member to provide an electrical capacitance. The gas capacity 
of the working chamber of the cylinder is varied according to 
displacement of the rod member into the cylindrical member. 
Thus, by measuring the variation in capacity, the displacement 
of the rod member relative to the cylindrical member can be 
determined precisely regardless of variations in the 
temperature of the gas in the cylinder or that of the outside 
air. Thus, the introduction of outside air into the cylinder 
will not hinder the functioning of the sensor.

Title: Filtering machine for fibrous substances
IPC: B01D33/15
Filed: 1990-03-07
Abstract: The invention discloses a machine for the filtering of solid, in 
particular fibrous, particles suspended in liquids, comprising a 
delivery chamber (2) collecting the liquid to be treated, a 
raceway (3) leading the liquid to be treated into a treatment 
chamber (4) having a cylindrical bottom (5), wherein there is at 
least one pair of revolving filters (6, 7), an overflow chamber 
(16) connected with a recycling tank and an area (21) for the 
discharge of the recovered solid particles. In said machine each 
filter (12) has a surface in the shape of a truncated cone and 
its horizontal axis is essentially perpendicular to the flow 
direction of the liquid to be treated, said two filters are co­
axial with each other and face each other, so as to form a 
concave space (20) therebetween. The taper of the filters causes 
the double effect of increasing the filtering performance of the 
machine and of avoiding its standstill when the delivery of 
liquid to be treated increases.

Filed: 1991-12-20
Abstract: Machining apparatus (150) comprises a boom (162) displaceable along spaced rails (158) and a carriage (174) displaceable along the boom (162) perpendicularly to the displacement direction of the boom. A machining station (178) is adjustably supported on the carriage (174) by three adjustment means (62) to adjust a machine head (180), such as a milling cutter, towards and away from a workpiece (151) disposed between the rails (158) beneath the machining station (178). Adjustment of the machine head (180) resutts from inaccuracies in the level of the rails (158) and/or the displacement of the carriage (174). Variations in the level of the rails (158) and/or carriage (174) are determined by a respective sensor (70) associated with each adjustment means (62) which monitors a reference defined by a planar laser beam (72). Alternatively one of the three adjustment means (62) between the machining station (178) and the carriage (174) may be replaced by a pivot (208) with the third adjustment means (224) being arranged to adjust the machine head (180) relative to the remainder of the machining station (178). In an alternative embodiment, the boom (26) is rotatable about a pivot support (18) within a cylindrical workpiece (12) with the machining station (34) mounted on the remote end of the boom (26) and optionally displaceable with a carriage (52) along the boom.
