A thin film electroluminescent display panel is fabricated by using ion implantation at selected locations in a host layer. By this method, strips of electroluminescent material with different dopants can be created, and these different stripes can be addressed by separate electrodes in order to obtain a multicolor display panel.

A wall or lining structure for shafts, ducts or barriers comprises panel members (11) supported by studs (10) having spaced paralleled flanges (13,15). The panels are held against the inner surface of at least one flange by an independent spacer member (14) having different cross-sectional dimensions in different directions. Different numbers of thicknesses of panel can be accommodated between the...

An acid gold electroplating bath contains gold in an electrodepositable form, (e.g. potassium gold cyanide), together with 3-(3-pyridyl) acrylic acid or 3-(3-quinolyl) acrylic acid, and optionally a metallic additive. The metallic additive is preferably a cobalt, nickel or iron salt.

A colorimetric detector such as a gas dosimeter, contains a strip-like carrier with a detection reagent in a transparent housing that can be opened at least at one end thereof. The detector is expanded in terms of its use to such reagent systems in which the pigment formed diffuses beyond the reaction zone. For this purpose, the detection reagent is provided such that it is contained in impregnate...

A mirror (24) absorbing radiation of wavelength greater than 4 micrometres and transparent to other radiation has an outer face opposite the object (20), and an inner face on which is placed a probe (32). The latter makes it possible to ascertain the temperature of the mirror, which itself is a function of that of the object (20) and of the ambient temperature. In order to avoid edge effects, the ...

Pesticidal compounds of formula I RACR3=CR4CHDRBI in which formula: RA represents a group ArCR1R2-in which Ar represents a phenyl or naphthyl group optionally substituted by one or more halogen, alkoxy, haloalkoxy, methylenedioxy, C1-C6 alkyl or haloalkyl groups; R1 and R2 together with the carbon to which they are attached represent a C3-C6 cycloalkyl group optionally substituted by one or more h...

Adjustable vehicle seat comprising a seat (1), which is supported by a frame (2) or by a frame-like part of the vehicle, and a back support (3), which may be pivotably connected with the seat (1) and can be folded forwards or backwards at right angles to the longitudinal direction of the seat (1), with the seat (1) being connected with the frame (2) via supporting means (5.1, 5.2) of which one or ...

The given digital word is fed to the input of a digital-analogue convertor (15) working with two reference voltages (V1, V2), the voltages being shifted dependent upon a binary control signal (b3) so that for a given binary value in the signal the first reference voltage (V1) is fed to a primary point (16) in the converter, and the second voltage (V2) fed to a secondary point (17). For the opposit...

The gripper (9) has two components (10,11) movable to and from one another, and which engage a load. The crane folding arm (7) is formed with a stirrup (20), and at least one component (10) of the gripper is insertable in the stirrup to be retained in a position alongside the folding arm (7).

An operating arrangement for a pivotable window 17 in a glass roof supported by beams 10 with lateral flanges 12 comprises a pneumatic piston assembly 20 which is mounted on one of the beams 10, which delimit those sides of the window opening, which are at right angles to the hinge axis 19 of the window and are parallel to the body part of the beam 10. The piston rod 21 of the piston assembly 20 i...

The combustion unit has an outer part (3) outside the heating boiler, and a component for introduction of combustion air from below through the perforated grid. Driven units (42) feed in fuel in stages from the outer part into the fire box (7), and others feed out slag and ash from the boiler. A number of spikes are distributed over the width of the fire box, and are impelled (50) over the length ...

A cathode for electrolytic cleaning of metals is claimed. A plate of for example, of stainless steel or titanium is welded to a supporting beam of the same material. The upper surface of the beam is explosively welded to a copper bar in such a way as to provide a good electrical contact between the metals. The copper is exposed on the undersides of the beam ends.
