Patent EP-0357399-A3 (EP)
IPC: H01M6/18
Filed: 1989-08-30
Abstract: An electrochemical cell is described comprising a relatively 
thin strip of anode material, first and second electrolyte 
layers coated on the opposing surfaces of the anode strip, and 
first and second relatively thin strips of cathode material 
contacting the first and second electrolyte layers, thereby

anode strip and a single cathode current conductor strip. 
The laminate strip is deformed such that both of the first 
and second strips of cathode material contact the single 
cathode current conductor strip along substantially the 
entire length thereof. In one embodiment, the cell takes 
the form of a spiral, in which the conductor strip is 
superposed to the laminate strip and the combination is 
rolled lengthwise, and in another embodiment, the cell takes

Patent EP-0370639-A3 (EP)
Title: Signal analysis
IPC: G01R23/16
Filed: 1989-10-30
Abstract: To analyse its spectrum, a radio signal is beat 
with an intermediate signal in a heterodyne circuit having 
a local oscillator (6) sweeping a range of intermediate 
frequencies. The oscillator signal also beats with the 
output from a comb generator (12) to produce signals 
marking intervals in its frequency sweep. The magnitude of 
the filtered intermediate frequency signal is measured 
between intervals marked by the frequency interval signals 
to output a frequency spectrum of the input signal. 
Preferably, the intermediate frequency signal is filtered 
in a homodyne demodulating unit employing a further 
local oscillator (74) tuned to the intermediate frequency. 
A spectrum data display employs a memory (34) storing the 
signal magnitudes at successive frequency steps at 
respective addresses associated with individual frequency 
steps. The magnitude values are assigned to their 
addresses by the spectrum frequency interval signals. For 
reading the stored data onto a two-dimensional 
magnitude:frequency display, control signals access the 
addresses and simultaneously step through the frequency 
dimension in the display. The signals read out from each 
address thereby generate magnitude values of the dispiay 
which are located at their appropriate frequency positions 
by the control signals.

Abstract: A device for amplifying an input optical 
signal includes an optical amplifier having a gain 
control region (14) in which the input optical signal is 
amplified, a first detecting region (13) for detecting 
the input optical signal, and a second detecting

The gain of the optical amplifier is controlled by a 
gain control signal from a signal source (17). A 
controller (18), responsive to detecting signals (S1,S2) from the 
first and second detecting regions (13,15), produces a 
source control signal which is supplied to control 
the signal source (17).

Title: Communication channel reallocation
IPC: H04Q11/04
Filed: 1989-11-21
Abstract: A call processing method and 
apparatus in which a channel that was 
allocated to one terminal for processing 
a call is reallocated to allow another 
terminal to process the call. The channel 
is one of several channels of the digital 
subscriber line (31, 41). In processing a call, 
the switching system (1000) allocates a channel for the 
exclusive use of a terminal (2300-2302, 2400-2404) sharing the 
digital subscriber line. While the channel is 
allocated to the terminal, only that 
terminal can use the channel. The switch enables 
another terminal sharing the digital 
subscriber line to process the call by reallocating 
the channel for the exclusive use of the other terminal.

Title: A composite ceramic-metal material
IPC: C04B38/00
Filed: 1990-07-18
Abstract: To date, highly porous ceramic materials have been infiltrated with a metal melt so that the product produced therefrom has a predominantly metallic structure. This ceramic-metal composite (CMC) is substantially metal-like in its properties, so that the requirements with regard to hardness, heat stability and wear are well below the values of the purely ceramic materials. The properties of the ceramic materials with regard to flexural strength, toughness, modulus of elasticity, hardness and resistance to wear are to be improved while retaining or increasing the properties such as hardness, temperature behaviour and resistance to wear, which are superior compared with metallic materials. The metal-ceramic composite is characterised in that the ceramic is composed of several layers, the layer thickness being between 10 and 150  mu m and the mean pore radius between 100 and 1000 nm with a final open porosity of 5-14% and a total porosity of 5-30%, and the metal fills the pore volume except for a residual pore volume of 0.1 to 10%, based on the initial porosity. The ceramic-metal composite is preferably used for binding to metal structures, such as welded or soldered ceramic/metal constructions.

Filed: 1990-11-12
Abstract: A heating plate for a domestic electric cooker has, in a known manner, a protector with a connecting block to which the leads coming from the domestic cooker controller are connected. Until now, the leads led from the connecting block to a further connecting block, which is likewise connected to the heating plate, from which the leads coming from the protector are connected to the heating resistors of the heating plate. It is intended to simplify the complete arrangement in such a manner that all the cable connections of a cable harness can be connected to a common plug on it. In this arrangement, it is also intended that the additional connecting block for making contact with the heating resistors for the heating plate be omitted. This object is achieved in accordance with the innovation in that all the connecting tabs (7) for plugging on a common plug of a cable harness are provided on the connecting block (6) for the protector. This solution according to the innovation allows the making of the contact with the heating plates to be significantly speeded up, it also being possible to use untrained personnel. The additional connecting block can be omitted. <IMAGE>

Title: Helicopter, high load rotor speed enhancement
IPC: G05D1/08
Filed: 1990-05-17
Abstract: A helicopter engine speed reference (66) is 
increased (113, 103-105) in response to heavy rotor 
loading (108). The reference speed is faded up (113, 
104) at a rather rapid rate to 107% of rated speed 
(114). After a fixed time interval (118), reduced 
rotor loading (119) will cause the reference speed to 
be faded down slowly (120, 103-105) to rated speed 
(121). If torque exceeds 111% of rated torque (117), 
the reference speed is similarly faded down (120, 
103-105).
