Title: Printed-circuit board for an indication board
IPC: H05K7/08
Filed: 1987-04-29
Abstract: As a rule, printed-circuit boards with conductor paths on both sides and through-plated contacts are used for boards with a high component density. In order to reduce this high cost, a simplification of the conductor path layout is proposed in which a printed-circuit board (1) for an indication board for information and display purposes is fitted with light-emitting diodes (4) and driver modules (5) such that the terminal legs (3) of the light-emitting diodes (4) are always connected by the shortest and direct route to the connecting pins (6) of the driver modules (5), without taking into account the circuit arrangement in the driver module (5). The jumble produced in this way is alleviated by a measured-value correlation in the driver module (5). <IMAGE>

Patent EP-0271740-A3 (EP)
Title: Device for switching an apparatus mounted in a vehicle on or off
IPC: B60R16/02
Filed: 1987-11-21
Abstract: As a rule, ignition locks of motor vehicles have three positions - "Off", "Park" and "On". This provides the opportunity firstly to switch off an electronic appliance fitted in the motor vehicle on leaving the vehicle, via the ignition lock, and secondly to operate such an appliance when the ignition is not switched on or the engine is not running. As a result of the new arrangement, these possibilities are also to be retained when ignition locks are used on which a park position is no longer provided. For this purpose, the switching device coupled to the ignition lock has a logic level corresponding to the current position of the ignition lock. In addition, a bistable trigger circuit is provided which, on every actuation of the additional switching device arranged in the electronic appliance itself, alters its switching status and supplies a logic level corresponding to the current switching status. The digital signals thus obtained are linked via a switching logic which generates the control signal necessary to switch the appliance on or off. The arrangement is particularly suited to car radios. <IMAGE>

Filed: 1987-11-05
Abstract: An infrared radiation detection device uses a pyroelectric 
polymer film (10), such as a poled vinylidene fluoride copolymer 
film, on one surface of which, facing incoming radiation, a front 
electrically resistive electrode (20) is disposed and on the 
opposite surface of which a back electrode (21) is disposed. 
Radiation absorption characteristics of the device for a given 
wavelength range of interest, for example 5 to 15µm, are 
optimised by giving the front electrode a high resistance per 
square value and forming the polymer film between the electrodes 
with an optical thickness substantially one quarter of a selected 
wavelength within the wavelength range at which wavelength 
radiation absorption at the front electrode is to be 
substantially a maximum. The back electrode preferably is 
reflective, having a low resistance per square. More detector 
elements may be provided defined by respective portions of a 
common polymer film.

Title: Method and apparatus for simultaneous detection of target gases in ambient air
IPC: G01N27/12
Filed: 1988-02-24
Abstract: A gas sensing thick film is positioned on an insulating 
substrate in contact with a pair of electrodes. A non-porous 
glass layer surrounds the film to stabilize it on the substrate. 
A heating element maintains the film at a preselected elevated 
temperature. The gas sensing thick film has a response 
characteristic for a preselected target gas to be detected which 
is enhanced by impregnating the film with platinum or palladium 
chlorine free compounds. The response characteristic of the gas 
sensing film is further increased by promoting combustion of 
interference gases on an outer filter layer fabricated of either 
conductive or nonconductive material. The incorporation of an 
insulating material between the gas sensing film and the outer 
filter layer also serves to increase the relative response of the 
gas sensing film to a preselected target gas.
Patent EP-0308266-A3 (EP)
IPC: H01L39/24
Filed: 1988-09-16
Abstract: A method and apparatus is disclosed for the 
formation of thin film superconducting oxide 
materials, for example materials of the general 
formula (A 1-x B x ) y Cu z O w , by deposition onto a 
substrate of the reaction products of a microwave 
excited plasma subjected additionally to a magnetic 
field and with the deposition being effected again 
under the action of magnetic and/or electric fields 
directed so as to obtain preferential crystal 
orientation and in some cases epitaxial crystal growth 
in the deposited film. By use of microwave excitation 
a hybrid resonance is established within the plasma 
leading to an abundance of excited oxygen within the 
plasma whereby the introduction of elemental 
constituents of the required superconducting oxide 
material, preferably in aerosol or spray form, can 
result in a plasma reaction wherein the 
superconducting material is the reaction product. If 
a spoiling agent is introduced additionally into the 
plasma in the first part of a two part process, a non-­
superconducting film of essentially the same crystal 
structure and crystal orientation as the required film 
can be deposited to form a surface for formation of 
the desired superconducting film.

Title: Ammunition loading device for a gun in a tank
IPC: F41A9/16
Filed: 1989-10-10
Abstract: A tank (1) with an overlying gun (2) which is mounted in a 
cradle (3) disposed on the crew turret (4) also includes a loading 
pendulum (16) which is disposed in a journal ring (15) pivotal in 
relation to the crew turret. The loading pendulum and the gun are 
asymmetrically journalled, which implies that the positions of the 
gun and the loading pendulum are dependent upon the elevation/­
depression of the gun. This problem is solved in that the gun is 
longitudinally/vertically displaced in the plane of elevation on 
elevation/depression. This is achieved in that the cradle is 
retractably disposed in the plane of elevation with the aid of a 
member (7) determining the degree of retraction, and that the gun 
may be elevated/depressed about an abutment (11) journalled in the 
revolving portion, or turret, and the gun, this abutment being 
movable in the plane of elevation. The above-mentioned devices (7, 
11) and the cradle are arranged so as, in the different 
elevations/depressions, to adapt the position of the breech of the 
gun to the pivotal movement of the loading pendulum about its 
pivotal centre (20).
