Mitnahme der jeweiligen Platine (1) verstellbar. Die Ansteue­
rung der definierten Verstellung kann auf mechanischem 
oder elektromechanischem Wege erfolgen, im letzteren Fall 
insbesondere über eine elektromagnetische Ansteuerung. 
Eine solche Ansteuerung ist erreichbar, wenn das Abdrucke­
lement (9) mittels eines Abdruckelement (9) mittels eines Ab­
druckmessers (25) bewegbar und in einer der beiden Stellun­

Patent EP-0201149-A3 (EP)
Title: Condition monitoring system (tyre pressure)
IPC: B60Q9/00
Filed: 1982-05-19
Abstract: A monitoring system for monitoring the condition in a vehicle wheel mounted tire. The system includes first and second LC circuits disposed within the tire and interconnected by a diode multiplier in series with a pressure switch. An exciter establishes an energetic electromagnetic field of a first frequency such that a first LC circuit is resonant at the same first frequency. This first frequency is converted into energy of a second frequency by a harmonic multiplier diode and is impressed upon a second LC circuit which is resonant at the second frequency, the second frequency being either an even or odd harmonic of the first (exciting) frequency. A receiver tuned to the second frequency interrogates the second LC circuit for presence of harmonic energy at the second frequency. A pressure switch opens when the tire pressure falls below a predetermined pressure which prevents activation of the second LC circuit so that the receiver will not sense the second frequency to which the second LC circuit is resonant, in which case there is provided an indication that the tire pressure is below the desired pressure. A scanner scans the receiver successively from one tire to another of a vehicle.

material in a cutting machine of the type retaining the mater­
ial by means of a vacuum applied from below the supporting bed 
is manufactured from a sheet of reticulated polyurethane foam 
material which has been compressed under heat and pressure so

of one inch and retained under pressure for 10 minutes at a 
temperature of about 400°F. In accordance with another 
embodiment, the supporting bed is manufactured from a composite 
structure of starting material including individual layers of 
reticulated foam material separated by layers of a hot melt 
adhesive web.

Abstract: The charging apparatus for lead-acid-accumulators controls 
the charging current and the charging voltage above the 
gassing voltage level according to a linearly declining 
characteristic. The charging current and the charging vol­
tage are converted to a current signal (50) and a voltage 
signal (60) which are normalised (70,80) and combined (150) 
into an indicating signal (160) which is constant as long 
as the charging current and the charging voltage follow the 
linear characteristic. A regulating device (130,140,40) 
compares the indicating signal (160) to a reference signal 
(132) for correcting the charging current and the charging 
voltage. The current signal (50) and the voltage signal 
(60) are converted to the indicating signal (160) by means 
of a weighted summation. For performing the summation there 
is provided an operational amplifier circuit.

Abstract: A process for preparing a porous polymeric filter body in which a 
deformable, porous, polymeric body, in which the 
porosity is in the form of a series of cavities jointed by 
interconnecting holes constituting a series of pathways through the 
body, is deformed comprises imparting a deformation to the polymeric 
body so as to change the dimensions of pathways so as to 
effect the filtering characteristics of the body with the polymeric 
body itself retaining the deformation so as to form a 
substantially rigid filter body. Filter bodies can thus be pre-formed 
or can be formed in situ to desired filtration 
characteristics.

Title: Methods and apparatus for measuring transverse dimensions of workpieces
IPC: G01B7/12
Filed: 1988-11-28
Abstract: In computer control of machine tools there is a need to 
measure the diameters of cylindrical workpieces automatically and 
preferably without touching the workpiece. For this purpose an 
inductive proximity sensor 14 is mounted for circular or linear 
movement along a path adjacent to a cylindrical workpiece 10 and 
in a plane normal to a radius of the workpiece. A discrete fast 
Fourier transform (FFT) is carried out on the output of the sensor 
as it moves along the path and the amplitude of the second ac 
component of the FFT is an indication of the workpiece diameter. 
By calibrating with workpieces of different diameters, the said 
amplitude can be used as a measure of workpiece diameter.
