Title: Wheel suspension
IPC: B60G11/14
Filed: 1988-08-05
Abstract: A helical compression spring (3), particularly for a wheel suspension, is presented and specified, with a spring strut  having a shock absorber and the helical compression spring (3) and connected on one side to the body and on the other to the wheel, and with a transverse control arm. 
<??>When the helical compression spring (3) according to the invention is used on a wheel suspension, the transverse forces occurring on the piston rod of the shock absorber are reduced in that the helical compression spring (3) has a curved spring centre line (7) in the unloaded state. Owing to the fact that the spring centre line (7) is curved, transverse forces (FX, FY) and moments (MO, MU) are initiated as a result of which the line of application (9) of the spring force does not coincide with the spring centre line (7).

Title: Antibody heteroconjugates for use in regulation of lymphocyte activity
IPC: A61K39/42
Filed: 1989-04-04
Abstract: The present invention relates to novel antibody heteroconjugates and their use in the enhancement or inhibition of T or B lymphocytes. The heteroconjugate are comprised of at least two molecules cross-linked to each other, each antibody being reactive with a different cell surface antigen on the same cell. The heteroconjugates appear to act by binding to lymphocytes via the interaction of the antibodies of the heteroconjugate with their respective cell surface antigens and bringing those antigens into physical proximity to each other, resulting in enhanced or reduced activation and function of the lymphocytes. The heteroconjugates, methods and compositions of this invention are therefore useful in the regulation of lymphocyte function, resulting in the improvement of cellular immune responses in various disease states.
Patent EP-0361497-A3 (EP)
IPC: G11C8/04
Filed: 1989-09-29
Abstract: A semiconductor memory unit suitable to be employed 
in a microcomputer system includes an address counter for 
fetching address information from an microcomputer in 
response to an address latch signal from the microcomputer.  
     The address counter further receives an updating control 
signal from the microcomputer and updates the fetched 
address information by one in response to each updating 
control signal. The memory device further includes a 
program memory for storing a string of instructions and 
an address decoder circuit for accessing the program 
memory in response to the address information from the 
address counter. Since the address information is 
updated by the updating control signal, the microcomputer 
fetches and executes the successive instructions without 
supplying the respective address information to the memory 
device.
Patent EP-0374487-A3 (EP)
IPC: C23C18/20
Filed: 1989-11-17
Abstract: Certain organic polymeric materials are capable of 
reversibly accepting or donating electrons from a 
reducing entity. The redox sites in the polymer accept 
electrons and, as a result, a change in the properties 
of the polymer occurs. This change is useful in 
modifying or etching the polymeric material. The 
material can be modified by incorporation of metallic 
seeds into the material at a controlled depth. The 
seeds are incorporated by interaction of cations of 
the metals with the redox sites in the polymer, which 
cause the reduction of the cations to form the neutral 
metallic seeds. Subsequent exposure of the polymeric 
material containing the seeds to an electroless bath 
causes further deposition of metal having the de­
sirable characteristic of good adhesion to the poly­
meric material. Etching of the polymeric material can 
be carried out as a result of an increase in solubility 
of the polymer in aprotic solvents when its redox 
sites have accepted electrons. The increased solubility 
allows openings to be etched in certain areas of the 
polymeric material that have been reduced, leaving 
other areas unchanged.

Title: Flat stationary field light beam scanning device
IPC: H01S3/101
Filed: 1989-10-06
Abstract: A light beam scanning device (100) and method 
comprises a first light source (102) for providing a 
scanning light beam (104) and a flat stationary scanning 
surface (134) to be scanned by the beam. An f sine theta 
slens system (136) focuses the light beam onto the flat 
stationary scanning surface. A galvanometer mirror (138) 
provides for repetitively scanning the light beam across 
the flat stationary scanning surface in a first fast scan 
direction while a pivoting mirror (140,142) provides for 
receiving the light beam (104) and scanning it onto the 
galvanometer mirror (138) in a second slow scan direction 
perpendicular to the first direction. The cooperative 
operation of the galvanometer mirror (138) and the 
pivoting mirror (140,142) raster scan the light beam (104) 
onto the flat stationary scanning surface (134). A second 
light source (150) generates a reference light beam (152) 
which is directed onto a rear mirror surface (138B) of the 
galvanometer mirror (138) from which it is directed to a 
nonlinear grating (154) having line spacing proportional 
to 1/(sine theta) for defining the position of the 
scanning beam in the first direction. The grating (154) 
is scanned by the reference beam (152) as it is reflected 
from the galvanometer mirror (138) and passes from the 
grating to a detector (156) for generating a control 
signal representative of the position of the scanning 
light beam (104) in the first direction. The grating 
(154) may be reciprocally moved relative to the 
galvanometer mirror to compensate for distortion of the 
image scanned in the flat stationary scanning surface 
(134).

Title: Method for controlling the peer-to-peer processing of a distributed application across a synchronous request/response interface using push-down stack automata
IPC: G06F11/14
Filed: 1989-07-24
Abstract: A method for coordinating recursive requests and responses 
in the peer-to-peer processing of a distributed application 
across a synchronous request/response interface. The method 
utilizes, on each side of the interface, a decision table and 
a local LIFO stack of generated and received requests, responses, 
and input from the application. The local stack is run in 
a push-pop manner and assists the local decision table in 
conducting the peer- to-peer processing until the LIFO stack 
becomes exhausted. A fault on either side of the interface 
results in undoing the processing by unwinding each stack back 
to a predetermined point. If one side operates as a persistent 
server, its application program environment is saved from 
one request to another by a dynamic save and simulated return 
to the application. Lastly, a request/demand is substituted 
for a demand/request by the server so as to change the server 
and requester roles of either side of the interface.

Title: A hydraulic active suspension system for a vehicle for controlling the attitude of vehicle body responding to lateral acceleration
IPC: B60G17/016
Filed: 1990-04-11
Abstract: In a hydraulic active suspension system, a plurality of 
actuators (1FR,1FL,1RR,1RL) having working 
fluid chambers (2FR,2FL,2RR,2RL) are provided corresponding 
to vehicle wheels. Each actuator is adapted to increase and 
decrease vehicle height in response to the pressure within its 
working chamber, which is controlled by a pressure control device. 
Vehicle speed and lateral acceleration are detected by 
corresponding sensors (234,238). A control device is further provided for 
controlling the pressure control device by compensating values 
determined based upon the lateral acceleration detected. The 
control device is adapted to reduce the compensating values in 
magnitude when the vehicle speed is lower than a predeterminate 
value under which the lateral acceleration sensor sometimes 
detects a flase lateral acceleration, thereby reduce the 
possibility that the vehicle body may generate an unpleasant roll 
due to the erroneous control on the pressures within the working 
fluid chambers based upon a flase lateral acceleration.
