Patent EP-0232223-A3 (EP)
IPC: C04B35/58
Filed: 1987-01-27
Abstract: A method for manufacturing ceramic/metal or ceramic/­
ceramic composite articles is disclosed. The articles can be 
useful for the production of aluminum in fused salt electroly­
sis cells, as armour plates for the protection against pro­
jectiles, cutting tools, or in abrasion resistance applications. 
The temperature slope of the process if optimized such that 
one of the reactants in the manufacturing proceeds through 
peritectic decomposition at a heating rate of low temperature 
increase for desirably uniform temperature distribution over 
the reaction mixture. Then the temperature increase is 
greatly elevated to obtain a reaction sintering condition for 
avoiding grain growth of undesired reaction products. Eleva­
ted temperature reaction sintering conditions can be main­
tained to decompose undesired components before they are 
entrapped by the reaction product.
Patent EP-0255502-A3 (EP)
Inventor: VAN CAMP GUIDO
IPC: B60K17/34
Filed: 1987-07-28
Abstract: Power distribution system in a more-axle transmission, 
where the power is distributed to the wheels diagonally-wise. 
This is based on the fact that in most of the situations the 
diagonal sums of the covered distances are nearly equal. 
Therefor the diagonal transmissionlines - transmitting the 
power to diagonal opposite wheels - are coupled. By in­
fluencing the couple distribution front/rear in each diagonal, 
we can use this system to steer the powerdistribution left/­
right on one axle determinated by the distances covered by 
the diagonally opposite wheels.

Title: Apparatus for continuous decaffeination of green coffee
IPC: A23F5/20
Filed: 1988-10-08
Abstract: During decaffeination of green coffee, the green coffee beans swell to about double their volume. To prevent blockage, coffee beans are therefore kept moving during the pre-swelling, but this leads to detachment, from the surface of the beans, of fine particles, which then clog an adsorber for caffeine adsorption. It is proposed that, at least in the first treatment step, a container is used whose side walls run at least substantially at an angle to each other, forming a conical container space.

Patent EP-0370616-A3 (EP)
Title: A control arrangement for an air core gauge
IPC: G01D13/22
Filed: 1989-10-16
Abstract: A control arrangement including a 
computer-based controller (30) and bipolar driver 
(20-28) for bidirectional current control of air core 
gauge coils (Sx,Sy) by pulse-width-modulation (PWM). 
The computer-based controller processes input 
information to determine the desired deflection of 
the pointer, and looks-up previously stored PWM duty 
cycle commands for energizing the gauge coils. The 
bipolar PWM drivers modulate the polarity of the 
voltage applied to the coils in accordance with the 
duty cycle commands. Since the drivers are bipolar, 
a zero strength magnetic field vector is achieved 
with a duty cycle command of 50 percent. This 
eliminates discontinuities in the region of zero 
strength magnetic field vector, and avoids the 
requirement of generating duty cycles of 0 percent 
and 100 percent to achieve a full 360 degrees of 
pointer deflection. Potential discontinuities in the 
generation of the duty cycles due to input data 
processing requirements is eliminated by scaling the 
duty cycles into the range of (DELTA)% to (100 - 
DELTA)%.

Title: Tensioning device for a ski boot
IPC: A43B5/04
Filed: 1990-09-10
Abstract: The shank of the clamping device is connected to the actuating element via a freewheel and is supported on the cover via a counteracting further freewheel. Located on the shank fixedly in the terms of rotation and displacement is the first coupling part which interacts with a second coupling part mounted at a fixed location. The latter is connected to the winding-up element for the clamping cables via a bevel gear. Formed on the actuating element is a slot-shaped groove which slides along the fixed guide pin during the pivoting of the actuating element. For tensioning the clamping cables, the actuating element is pivoted in such a way that the groove part is located at the guide pine. The shank is thereby lifted into the upper clamping position and the coupling is closed. During the pivoting of the actuating element to and fro, the clamping cables are wound onto the winding-up element. To release the clamping cables, the actuating element is pivoted in such a way that the groove part is located at the guide pin. The shank is thereby lowered into the lower release position, the first coupling part separating from the second coupling part. The winding-up element is thereby freely rotatable.
