Patent EP-0250113-A3 (EP)
IPC: B60C11/24
Filed: 1987-05-29
Abstract: In order to detect early uneven wear patterns on new tires 
resulting from vehicle misalignment, the treads of the tires are 
provided with groups (8,10) of grooves of varying depths, so that the 
grooves will wear away at varying rates. Preferably a group (8,10) of 
at least five grooves is provided on the outermost ribs of the 
tire adjacent each shoulder (6) and at the same circumferential 
position. Also, the grooves (8,10) are preferably made of different 
lengths corresponding to their depths for easy identification. 
By observing how fast the grooves of one group on one shoulder 
rib wear away relative to the grooves on the other shoulder rib, 
uneven wear of the shoulder ribs can be detected at an early time 
in the tire's life.

IPC: H01R13/71
Filed: 1987-07-15
Abstract: The connector is of the type allowing signals generated 
in a communication apparatus or the like to be measured or switched 
without instantaneous shut-off. The connector is made up of a 
socket (32) having two first contacts (38, 40) which resiliently 
make contact with each other, and a plug (34) having two second 
contacts which engage the first contacts respectively as the 
plug is pushed into the socket. The plug also has a projection 
(46c), or breaking member, which is made of an insulating 
material. When the plug is fully inserted into the socket, 
the projection forces the first contacts (38, 40) apart and 
interrupts the resilient contact therebetweeen.

in a substantially uniform mixture, and 
cutting said spheres into short fibres by 
the aid of beating knives, a hammer mill 
or the like, and then conveying said 
medium to the growing site or to a packaging 
by the aid of an air jet.

Title: Method and circuit for trimming the frequency of a frequmethod and circuit for trimming the frequency of a frequency source ency source
IPC: H04B7/24
Filed: 1988-10-19
Abstract: In order to adjust the frequency of an oscillator in a substation of a network to a reference frequency of the network, a reference station is provided with a high precision oscillator which is connected to a clock input of a counter. If this counter has a defined counting state, a start signal is generated and transmitted to said substation. At another defined counting state a stop signal is generated and transmitted to said substation. In the substation the oscillator to be adjusted is connected to a local counter, which counts the pulses of the oscillator between said start and stop signals. The count of this counter then is used as a measure for the frequency deviation of the oscillator and can be used for generating a control signal to adjust the frequency of the oscillator of the substation.

IPC: B05B15/10
Filed: 1988-05-23
Abstract: A sprinkler includes a housing (11) with an inlet port (23) 
through which to supply a flow of liquid to the housing (11) 
interior and a stem (12) disposed at least partially within the 
interior of the housing (11) for movement between a retracted 
position and an extended position. A piston (50) disposed 
within the interior of the housing (11) responds to the flow of 
liquid to move the stem (12) from the retracted position to the 
extended position. The stem (12) defines a passageway 
extending from a lower portion of the stem (12) to an upper 
portion of the stem, and the lower portion of the stem 
defines an opening (30) through which the flow of liquid can 
pass from the interior of the housing (11) into the passageway. 
A valve element (33) moveably mounted on the stem (12) at least 
partially blocks the opening (30), and a shaft (15) rotatably 
mounted on the housing (11) extends to a position outside of 
the interior of the housing (11). The shaft (15) is coupled to the 
valve element (33) so that the valve (33) can be rotated by rotation 
of the shaft (15) for purposes of restricting the flow of 
liquid through the opening (30) a selected amount.

Title: Shock absorber with an adjustable damping characteristic
IPC: B60G17/08
Filed: 1989-05-05
Abstract: A shock absorber wherein a piston divides the internal space of a cylinder into two cylinder chambers and has a passage of variable cross-sectional area for the flow of damping fluid between the cylinder chambers. The piston has a first section which is connected with a piston rod and is in sliding engagement with the internal surface of the cylinder, and a second section which is reciprocable in the first section and has two sets of surfaces which are acted upon by damping fluid. The passage is defined by the two sections. One set of surfaces is acted upon by damping fluid which is pressurized as a result of axial movement of the piston in the cylinder, and the other set of surfaces is acted upon by damping fluid which fills a plenum chamber of the piston and is acted upon by a valving element forming part of an electrically operated fluid pressure regulating unit. The difference between the forces which the damping fluid applies to the two sets of surfaces determines the axial positions of the two sections of the piston with reference to each other and hence the cross-sectional area of the passage for the flow of damping fluid between the cylinder chambers.

Title: Colloidal composition and its use in the production of paper and paperboard
IPC: D21H17/43
Filed: 1989-09-19
Abstract: The composition comprises a water dispersible colloidal 
siliceous material, such as a swelling clay, in intimate 
association with a low molecular weight water soluble high 
charge density organic polymer, such as a polyacrylic acid

Abstract: A print head for a light emitting diode printer has a 
row of LEDs (11) on a mother plate (10) and an end mounting 
plate (16) secured at each end of the mother plate (10). A 
linear lens array (14) is positioned over the LEDs (11).

image analyzer (41) for analyzing the quality of image from 
an individual LED (11) projected onto the face of the 
analyzer (41). The total conjugate or spacing between the

optical analyzer (41). The spacing of the second end of the 
lens array (14) is then adjusted for maximizing the quality 
of an image of an LED (11) near the other end of the row 
(11). The adjustment steps may be repeated for optimizing 
the LED images. After adjustment, the position of the lens 
array (14) is locked in the end mounting plates (16). A

locked against a reference surface (48) on the analyzer 
(41). when the print head is mounted in a printer, the 
reference surfaces (38,39) on the end mounting plates (16) 
serve to position the print head with the LED images focused 
on the photoreceptive surface (36) of the printer.

Title: Low dielectric composite substrate
IPC: H05K1/03
Filed: 1989-02-28
Abstract: The cracking experienced during thermal cycling of 
metal:dielectric semiconductor packages results from a 
mismatch in thermal co-efficients of expansion. The 
non-hermeticity associated with such cracking can be 
addressed by backfilling the permeable cracks (33) with a 
flexible material (35). Uniform gaps between the metal 
(32) and dielectric materials (31) can similarly be filled 
with flexible materials to provide stress relief, bulk 
compressibility and strength to the package. Furthermore, 
a permeable, skeletal dielectric can be fabricated as a 
fired, multilayer structure having sintered metallurgy and 
subsequently infused with a flexible, temperature-stable 
material to provide hermeticity and strength.
