Title: A conductor assembly for connection to electrical switches, modular electrical apparatus and the like
IPC: H01R27/00
Filed: 1987-07-02
Abstract: A conductive bar structure suitable for connection to electrical 
switches or other modular electrical apparatus has two or more 
electrically conductive strips (1) housed in an elongate insulating 
casing (3) having an opening along one side which is closable by a 
removable cover (5) in which are formed a plurality of longitudinal 
slots (6) the length of which is parallel to the length of the 
casing. Within the casing (3) there are a plurality of 
longitudinally extending insulating partitions (10) defining guide 
channels (2) in which the bars (1) are housed so as to be separated 
and insulated from one another.  
     Each bar (1) has a plurality of lateral projections (7) lying in a 
plane parallel to but offset from the general plane of the bar (1) 
itself, the degree of offset being determined by the channel in 
which the bar (1) is intended to be fitted so that the projections 
can extend through the slots in the cover. Unwanted projections 
can be removed at a convenient weakened line at the root of the 
projection.

Title: Memory testing device
IPC: G11C29/00
Filed: 1988-12-27
Abstract: In a memory testing device for testing a memory capable of 
effecting a write and a read in pixel, plane and block mo­
des, there are provided a pattrn generator (100) for gene­
rating an address and data for supply to the memory under 
test (200) and a buffer memory (400) which has memory chips 
equal in number to the square of the number of bits of the 
data. The same data as that to be written in the memory un­
der test is written in the buffer memory in the same mode 
as in the memory under test, and the data is read out in 
the same mode as in the memory under test. The data thus 
read out of the buffer memory is used an expected value 
data for logical comparison with data read out of the me­
mory under test.

and  
    R′ is C₁₄ - C₂₆ saturated alkyl or 
C₁₈ - C₂₄ mono-olefinically unsaturated alkyl 
C₁₈ - C₂₄ mono-olefinically unsaturated alkyl  
provided that: 
   (a) when both R and R′ are saturated alkyl, 
 
 
there also is present an unsaturated or mixed 
unsaturated secondary amide of said formula (i.e. in 
which at least one of R and R′ is unsaturated alkyl),    (a) when both R and R¹ are saturated alkyl, 
there also is present an unsaturated or mixed 
unsaturated secondary amide of said formula (i.e. in 
which at least one of R and R′ is unsaturated alkyl),    (b) when R is unsaturated alkyl and R′ is 
saturated alkyl, there also is present a saturated, or 
unsaturated amide of said formula or a mixed 
unsaturated secondary amide of said formula in which R 
is saturated alkyl and/or R′ is unsaturated alkyl    (c) when R is unsaturated C₁₇-C₁₈ alkyl 
and/or R′ is unsaturated C₁₈-C₁₉ alkyl, the 
interpolymer is compositionally uniform, and    (d) when R is saturated alkyl and R′ is 
unsaturated alkyl, the interpolymer is randomly 
compositionally uniform.

IPC: G05B19/4062
Filed: 1988-04-11
Abstract: A microprocessor (32) periodically tests the status of the stem (40) 
of the motor operated valve (22), and turns off the valve's motor 
(24) if certain predefined criteria for the valve stem position 
and the valve stem load are satisfied. A position sensor (46) 
provides a valve stem position signal and a predicted stem position 
signal is computed. The current and predicted positions are 
compared with a preselected target position. A stem load sensor 
(48) provides a current valve stem load signal, a predicted stem 
load is computed and the current and predicted loads are compared 
with a preselected maximum desirable stem load.  
     When the control system is being used to fully open and fully close 
a gate valve, the control logic can use either a predicted position 
criterion or a predicted stem load criterion to determine when to 
turn off the valve motor (24). When the control system is being 
used with a flow control valve, the use of a predicted position 
criterion minimizes overshoot problems which would cause the motor 
(24) to be reversed one or more times while moving to a target 
position.  
     A motor load sensor (70) allows periodic measuring of the actual 
load on the motor (24). The motor is turned off if the 
measured motor load exceeds any one of a plurality of preselected 
maximum motor load values for a corresponding predicted period of 
time.

Abstract: Poly(butylene terephthalate) is prepared in a two-stage 
process wherein terephthalic acid and 1,4-butanediol are 
esterified in the presence of a catalytic amount of a catalyst 
having an organo-metallic component which is an organo-titanate 
compound, an organo-tin compound or a combination thereof and a 
salt component which is an organic acid salt or an inorganic 
salt. In a second step, the esterification product is subject 
to polycondensation. By following the foregoing procedure, the 
formation of tetrahydrofuran is significantly suppressed and 
the percent conversion of esterification products increased.

Title: A semiconductor device suitable for cryogenic operations
IPC: H01L29/66
Filed: 1989-04-11
Abstract: A semiconductor device for operation under 
cryogenic conditions has a structure similar to that of 
conventional bipolar transistors, but a different 
impurity doping profile. The impurity concentration 
for a "base" layer (14) of the device is controlled to 
be larger than 5 x 10¹⁸ cm⁻³, preferably 1 x 10¹⁹ cm⁻³ 
or more, and the impurity concentration for an 
"emitter" layer (15) is controlled to be in a limited 
range less than the above value, but greater than 
1 x 10¹⁷ cm⁻³. The above doping profile enables the 
device to operate satisfactorily from temperatures below 
about minus 100 decrees centigrade down to liquid 
nitrogen temperatures and further makes it suitable 
for a high-speed operation.

Title: Noise reduction for photodiode arrays
IPC: H03F3/08
Filed: 1989-11-24
Abstract: A method and apparatus for reducing noise in a light sensing 
circuit having a photodiode array (80) coupled to a charge amplifier (85) 
through a field effect transistor transfer switch (116). Thermal noise 
generated by the transfer switch (116) is combined with image signals 
inputted to the charge amplifier (85) resulting in an outputted noisy 
image signal. The invention eliminates this noise by taking two 
consecutive readings of the charge amplifier output, one before and 
one after closing the transfer switch (116) and after opening it. The 
thermal noise generated by the transfer switch (116), and added to the 
next reading of the charge amplifier output, is equal to the 
difference between these two readings. Once stored, this 
difference can be subtracted from the previously mentioned "next 
reading", resulting in the elimination of this noise term.

Title: Tube having a structure made from cement, method and machine for manufacturing it
IPC: F16L9/08
Filed: 1989-05-30
Abstract: The present invention relates to a tube (1) made from 
cement and having a layer structure, the use of which is 
destined in particular to the hydraulic/building field. 
Said tube shows the characteristic that the usual 
asbestos fibres used in order to reinforce such kind of 
articles have been replaced by other fibres having 
similar functional features, for example of cellulose, at 
the inner surface (3) of said tube, which is destined to come 
into contact with the liquid conveyed inside the same 
tube. In correspondence of said inner surface, the usual 
Portland cement can be replaced by cement endowed with 
resistance to aggressive waters. The process for 
manufacturing such a tube consists in depositing at least 
two layers of reinforced cement mortar on a core, the 
outer diameter of which coincides with the inner diameter 
of the tube, and in such a way that such layers set 
simultaneously to the other layers, forming one enbloc 
cement structure, even if reiforced with different 
reinforcing materials.  
     The machine (10) for producing such a tube is equipped 
with a plurality of tanks (7,8) from which by means of conveyor 
belt (4) and of roll means (3,11,14,15) the cement mixture in the fluid 
state is alternatively drawn, which has to be deposited 
together with the fibres contained in it as layers on a 
core used in order to form the tube.
