Patent EP-0375094-A3 (EP)
Title: Method and device for the hot-rolling of strip
IPC: B21B37/16
Filed: 1989-12-22
Abstract: The invention relates to a method and a device for controlling the strip width during the hot-rolling of strip on a multiple-stand finishing line of a rolling mill train in which the speeds of the working rolls of each stand are controlled as a function of the instantaneous operating state. Here, the strip widths are sensed directly after the last reduction per pass and/or before the penultimate reduction per pass and are compared with the desired width in a width controller. In the event of deviations, a strip-supply controller for the strip supply between the last stands is acted upon, which strip-supply controller, by adjusting the roll nips, corrects the strip supply and the tensile stress of the strip in such a way that the strip width changes. The method is optimized by additional control of the strip thickness according to the novel strip-supply principle as well as by dispensing with some loop lifters. <IMAGE>
Patent EP-0332286-A3 (EP)
Title: Programmable protocol analyzer
IPC: H04L69/40
Filed: 1989-01-25
Abstract: The programmable protocol analyzer enables a user to 
specify (102-106) one or more fields (501-526) that are 
to be monitored (107-109) by the protocol analyzer and 
displayed (110-111) to the user. The specified fields 
(501-526) can be selected (103-104) from a menu of 
predefined fields (501-526) in the frame of data or can 
be user defined fields (524) of arbitrary length and 
position in the frame (Frame) of data. The programmable 
protocol analyzer excerpts (107-109) these specified 
fields (501-526) from the transmitted frame (Frame) of 
data, stores the specified fields (501-526) in a memory 
and displays (110-111) the data contained in the 
specified fields (501-526) to the user. This 
programmable protocol analyzer thereby permits a user to 
monitor and display only the particular segments of the 
frame (Frame) of data that are of interest to the user. 
This arrangement filters out the extraneous information 
contained in the frame (Frame) of data in order that the 
user can concentrate on only the particular fields (501-­
526) that are most relevant to the test being performed 
by the user.
Patent EP-0344951-A3 (EP)
IPC: G06F9/28
Filed: 1989-05-19
Abstract: An improved computer processor capable of executing software 
instructions at two rates has two sets of microinstructions in a 
microsequencer (16), one for executing software instructions at 
a first rate and a second for executing instructions at a second 
rate. The speed of execution is controlled by a speed bit 
stored in a latch (40) which, depending on the value of the speed 
bit, selects microinstructions from either the first or second 
set. The speed bit is set to a first state by a software 
instruction included in blocks of software instructions to be 
executed at a first rate. The bit is automatically set to a 
second state upon execution of blocks of software instructions 
which do not contain a software instruction to set the bit to 
the first state such that these blocks are automatically 
executed at the second rate. The speed bit of a block of 
instructions which is interrupted by interrupt logic (30) or 
by a subroutine is stored in a subroutine stack (34) together 
with the address of the interruption in the program.

Patent EP-0380354-A3 (EP)
Title: Underground pipe leak detection system
IPC: G01M3/22
Filed: 1990-01-26
Abstract: An apparatus and method for detecting leaks in 
underground fluid pipes. Detection of a leak is achieved 
by introducing a liquid phase tracer into the fluid 
within the underground pipe (3), which volatilizes to a gas 
phase when the fluid leaks from the underground fluid 
pipe. A permeable tube (12) is buried in the soil in a 
position above an underground fluid transfer pipe. At 
least on end of the permeable tube is terminated in a 
recess vault (14) for access to the end of the permeable tube 
and sampling soil gases from the permeable tube. Should 
any fluid leak (15) occur in the underground fluid transfer 
pipe, the escaping tracer escapes in liquid form and, 
upon encountering free air in the subsurface soil, 
vaporizes to the gas phase and diffuses through the soil 
surrounding the underground fluid transfer pipe and into 
the permeable tube for collection and analysis.

Title: Oil-in-water emulsions
Inventor: DAHMS GERD HERBERT
IPC: B01F23/00
Filed: 1993-01-26
Abstract: An oil-in-water emulsion containing 0.5% to 30% metallic oxides having a particle size of less than 0.2 micron, less than 10% total emulsifier, 5% to 30% of an oil phase and at least 60% of an aqueous phase is provided. The invention also makes available a method of preparing such emulsions in which the emulsion is formed by use of a dispersion in water of the metallic oxide particles. By comparison with previously known emulsions of this type relatively small quantities of emulsifiers are used and it is possible to use an emulsion system with a low HLB value (e.g. less than 6). Preferably no hydrophilic emulsifiers are used. The emulsions are suitable for preparing UV-absorbing compositions such as sunscreens, moisturisers and after-sun lotions. The ability to use no, or little, hydrophilic emulsifiers is advantageous since, in, general, these emulsifiers are not biodegradable whereas hydrophobic emulsifiers generally are biodegradable.

Patent EP-0694883-A3 (EP)
Inventor: SAKURAI TAKASHI
IPC: H04W4/04
Filed: 1995-07-19
Abstract: After a vehicle-mounted unit determines that a
vehicle has entered a toll chargeable area (101, 301), if
communication is determined to be allowable through a flag F
(102), communication operations are performed (103, 303) and
after finishing communication operations, the flag F is set
and communication operations thereafter are prohibited (104).
Next, the unit determines if a travel distance N has exceeded
a toll chargeable distance A (105, 307). The travel distance
N is measured by counting the number of vehicular speed pulses
received after the end of the communication operations (Steps
201, 202), and the toll chargeable distance A is set to be
equal or greater than the travel distance needed by the
vehicle to enter the communication area and leave it. If it
is determined that travel distance N has exceeded toll
chargeable distance (307), the flag F is reset, communication
prohibition is released and communication thereafter is
allowed (106).

Abstract: A cordless telephone arranged for operation in a frequency hopping system
includes multiple portable units configured for operation with a base unit and with each other
by having the base unit pseudo randomly select from a plurality of communication channels
available in the frequency hopping system a different starting channel for each one of the
portable units. Each portable unit then provides initial communications with the base unit
over the selected starting channel of the portable unit. For maintaining communications
during a frequency hopping cycle between a portable unit and the base unit, the portable unit
and base unit both generate a set of communication channels from the starting channel
assigned to the portable unit for subsequent use in communicating over the radio frequency
link. Each of the portable units is configured for operation with the base unit and with each
other during a registration procedure. Information indicative of the starting channel for each
portable unit and also a security code is transmitted to each of the portable units from the
base unit during this registration procedure and on a predetermined communication channel
at a radiated energy level well below the level normally used for normal communications.
