Patent EP-0296509-A3 (EP)
IPC: B60N2/90
Filed: 1988-06-18
Abstract: A vehicle seat (1) mounted for relative 
vertical movement has, a rolling lobe air spring 
support (2). The air spring (2) includes a piston 
(24), a plug (26) and a flexible tubular sleeve (25) 
extending between and connected at its opposite ends to 
the piston (24) and plug (26). The piston (24) has a 
positively, radially outwardly tapered control surface 
(56) on the piston sidewall (28). The control surface 
(56) has a plurality of segments of different 
respective tapers. The positive taper of the control 
surface (56) has a composite radial increase in 
segmented steps from (58, 59, 60) to control surface end 
closest to the plug to the control surface end farthest 
from the plug. The segmented, positive taper piston 
control surface (56) provides a variable spring rate as 
the tubular sleeve lobe (37) rolls along the piston 
control surface (56) during spring compression caused 
by seat loading. The variable spring rate created by 
the piston control surface provides a soft feel to the 
seat occupant under normal load conditions and provides 
rapid air pressure build up in the air spring (2) 
during increased load conditions to slow or arrest seat 
movement. The positively tapered control surface 
provides a progressively larger piston area giving the 
piston (24) more lifting ability at the same pressure 
increases as the lobe (37) rolls down the piston (24). 
The pressure increases faster and the piston (24) also 
becomes more effective as the lobe (37) rolls down the 
surface as compared to a cylindrical or negative taper 
piston.

Patent EP-0276935-A3 (EP)
IPC: G01N11/00
Filed: 1988-01-18
Abstract: Apparatus for unattended retrieval of samples 
of material to be tested for viscosity provides 
substantially continuous monitoring capability for 
a blending plant. A single device is used for both 
retrieving the samples from a pipe (10) conveying the 
material and for delivering the samples to a 
measuring chamber of a viscometer. The device, 
such as a pump (12, 14) or a solenoid operated valve, is 
controlled by a sequence timer (16) programmed to 
generate a timed sequence of signals. Preferably, 
the device is operated to provide a new sample to 
the viscometer when the measuring chamber is being 
heated, thereby displacing the previous sample 
without requiring a cleansing agent.

Title: Process for microinjection into living cells and apparatus therefor
IPC: C12M3/00
Filed: 1989-02-16
Abstract: In the microinjection of liquids or suspensions of substances into living cells, a stage and a needle, which is movably mounted and inclined with respect to the latter, are connected together so as to be movable relative to one another. The cells are located in a culture vessel on the stage. The needle is adjusted, by moving in a plane z1 which is parallel to the stage above the cell material, with its tip as pointer above a cell so that the tip of the needle is located exactly over the required injection site. Then the needle is moved backwards, depending on the angle of inclination of the needle to the said plane in a direction which is determined by the direction of the needle in its projection onto the plane, by a distance which is so long that, at the end of the backwards movement, the needle is in a position in which the extended axial direction intercepts the cell at the required injection site. The needle is then moved axially to puncture the cell, after which the direction of movement of the needle is reversed.
