Patent EP-0191232-A3 (EP)
IPC: B24B5/06
Filed: 1985-12-10
Abstract: In the internal grinding of a cylindrical bore having an 
oil or similar groove which adversely affects the bore round­
ness achievable, one or more streams of liquid coolant are 
directed over the grinding wheel during rough grinding at 
a high wheel feed rate and only a mist of liquid coolant 
droplets suspended in a compressed air stream is directed 
over the wheel once the high wheel feed rate has been 
reduced to the lower wheel feed rate associated with finish 
grinding. Means are provided for terminating the liquid 
coolant streams at the time the wheel feed rate is changed 
or after a short delay period thereafter to establish equili­
brium finish grind conditions. Preferably, the change from 
one or more liquid coolant streams to the coolant mist is 
made in response to a detected decrease in wheel spindle 
motor power.
Patent EP-0192021-A3 (EP)
IPC: G06F3/12
Filed: 1986-01-02
Abstract: A process for the modification of device configuration in a 
computer system is designed to be easy-to-use by the user of 
the computer system yet allow the user flexibility in the 
specification of device configuration. The computer system stores 
parameter values of various default devices and devices already 
installed in the computer system. When the user invokes an 
"ADDDEV" command, the system prompts the user to enter one of a 
plurality of commands such as add, change or delete. Assuming 
the user enters the add command, the system prompts the user to enter 
the name of a default device or a similar device already 
installed in the system. When that information is entered by the user, 
the system determines from the stored parameters for 
the default or similar device which parameters must be re-specified by 
the user for the device to be added to the system. The 
system then prompts the user to enter only those parameters requiring 
respecification. Once those 
       parameters have been respecified, the system stores the 
respecified parameters together with those parameters common to 
both the default or similar device and the added device thereby 
installing the added device in the computer system.

Abstract: A thermal imaging device uses a compensated cholesteric 
liquid crystal mixture (1) as its thermooptic conversion el­
ement. The mixture is obtained by mixing two cholesteric liquid 
crystals, one with a left-handed twist and the other with a right-­

Abstract: An electronic board, e.g. a planning board, has a 
plurality of rows and columns of mechanical coupling 
means (see fig. 10) and electrically conducting contact 
areas, respectively, and moreover comprises a plurality 
of marking elements (70-74, P, S, H, J, E, L, M) adapted 
to be secured mechanically to the board in a large 
number of various positions and also adapted to provide 
electric contact between the electric identification 
circuits in the marking elements and a plurality of 
contact areas in the board, so that electric information 
may be transferred in both directions between the mark­
ing elements and the board. This entails that the elec­
tronic board enables visualization of data information 
in the form of a spatial position on the board as well 
as in the form of individual marking, and conversion of 
visual information of the latter type into data informa­
tion signals. The electronic scanning of the board can 
be established rapidly in that a plurality of contact 
areas in the board, disposed in the same row and column, 
respectively, are interconnected to a respective 
terminal on an X and Y circuit, respectively.

IPC: C10G3/00
Filed: 1987-07-17
Abstract: A multistage process for producing isoalkyl ethers from lower 
aliphatic oxygenate feedstock, such as methanol. Feedstock is 
catalytically converted in a primary catalyst stage at elevated 
temperature in contact with zeolite catalyst to predominantly 
C₂-C₇, for example C₂-C₅, lower olefins comprising 
isobutylene and isoamylene, by-product water and a minor amount of 
C₈⁺, for example C₆⁺, hydrocarbons, followed by 
fractionation of the C₂-C₇, for example C₂-C₅, olefins to 
recover a C₂-C₃-rich recycle stream for further catalytic 
conversion in the primary stage. C₄-C₇, for example C₄-C₅, 
olefins are passed to a second catalytic etherification stage for 
reaction of isoalkenes with methanol to produce methyl 
tertiary-butyl ether, methyl isoamylether and higher isoalkyl 
ethers. The second stage effluent may be fractionated to recover an 
ether product, C₅⁺ hydrocarbon liquid product, and unreacted 
butenes. Advantageously, the unreacted butenes are further reacted 
with isoparaffin in a third catalytic stage under acid catalysis 
alkylation conditions, and fractionated to recover C₆⁺ alkylate 
liquid, liquid hydrocarbon product. The ethers may be blended with 
at least one C₆⁺ hydrocarbon to produce high octane gasoline.

Title: Actuator with built-in pilot valve
IPC: F16H59/42
Filed: 1988-02-24
Abstract: An actuator has a pilot valve incorporated in a 
piston thereof which is slidably disposed in a cylinder 
tube, the piston having first and second piston lands 
slidably disposed in first and second coaxial cylinder 
chambers. A spool valve body has first and second spool 
lands slidably disposed in an inner hole in the piston. 
When the spool valve body is moved in one direction, a 
first axial passage in the piston communicates with a 
pressure sink through a first return port which is opened 
by the first spool land, and a second axial passage in the 
piston communicates with a portion of the inner hole in 
front of the second spool land through a second supply port 
which is opened by the second spool land. When the spool 
valve body is moved in the opposite direction, the second 
axial passage communicates with the pressure sink through a 
second return passage which is opened by the second spool 
land, and the first axial passage communicates with a 
portion of the inner hole in front of the first spool land 
through a first supply port which is opened by the first 
spool land. The spool valve body is movable under a 
differential pressure between two inlet ports. The pilot 
valve can amplify the operating force on the piston even if 
the difference between applied input oil pressures is 
small. In addition, the actuator is compact in size.

IPC: H01L23/48
Filed: 1989-08-28
Abstract: An improved contact is obtained to power devices 
having a raised dielectric region (18) adjacent the die 
contact region (22) by providing a contact dimple 
(32,42,52) on the otherwise flat metal lead (30,40,50) 
used for die contact. The dimple (32,42,52) is arranged 
above the die contact (22) and soldered thereto. The 
radius of curvature and depth of the dimple is adjusted so 
that the contact lead (30,40,50) is far enough away from 
the edge of the surrounding raised dielectric (18) at the 
edge (34) of the die contact (22) to provide a laterally 
concave outward air-solder interface in that location. 
This prevents solder creep onto the dielectric surface 
(23) and avoids die edge shorting. Several dimpole shapes 
(32,42,52) are described.
