Patent EP-0174743-A3 (EP)
IPC: C01B21/06
Filed: 1985-08-13
Abstract: Chemical vapour deposition process for depositing a 
transition metal nitride coating on a substrate. The coating has 
utility as a conductor in a microelectronic device. The transition 
metal source material for the process is a transition metal azide or 
aliphatic amine, optionally halogenated, which is a liquid at 
bubbler temperature. The compound is transported to a deposition 
chamber containing a substrate; in one embodiment transport is 
effected by a carrier gas comprising a mixture of hydrogen with 
hydrazine vapour or nitrogen. The deposition chamber containing the 
substrate is maintained under pyrolytic conditions to decompose the 
transition metal compound source material and to form a transition 
metal nitride on the substrate.
Patent EP-0180419-A3 (EP)
IPC: B41M1/10
Filed: 1985-10-24
Abstract: An intaglio plate for a pad or gravure printing 
method comprises a base plate 1 having a flat-bottomed 
recess 2 formed in the surface thereof.  A resin 
intaglio printing plate 4 is securely attached within 
the recess to the base plate, that printing plate having 
the design to be printed formed therein for example by a 
photographic process.  The upper surface of the resin 
plate is substantially co-planar with or just below the 
surface of the base plate 1, so that when the intaglio 
plate is doctored by means of a suitable doctor blade, 
the pressure force of the doctor blade is borne largely 
by the base plate and not by the resin plate.

Title: Method for storing voice information intended for a subscriber of a communication system in a central memory unit
IPC: G06F3/16
Filed: 1986-03-07
Abstract: The voice information is represented within a framework of synchronous operating sequences as pulse-code modulated data words obtained from samples. Before storage, a preprocessing (VA1) takes place for the purpose of bit rate reduction. During this process, several samples are in each case combined to form a new information word for which a synchronous transmission to the memory unit (SP) is provided. For this purpose, this new information word contains a preceding start bit and at least one terminating stop bit in addition to the user part. Although the new information word is based on the PCM bit clock for determining the word format, it is only transmitted to the memory device when there is also data present. <IMAGE>

Patent EP-0254992-A3 (EP)
IPC: G01R19/165
Filed: 1987-07-17
Abstract: The duration of time during which an AC power voltage 
sinusoidal waveform remains between negative voltage 
threshold -V1 volts, nominally 5% of negative peak voltage 
-V2 volts, and positive voltage threshold +V1 volts, nomi­
nally 5% of peak positive voltage +V2 volts, is detected. By 
the change in voltage with time exhibited by a sinusoidal 
waveform in the region of zero voltage crossing, the expected 
time duration between voltage thresholds is approximately 
5% of one-half period of such sinusoidal waveform. If the 
actual time between voltage thresholds exceeds (nominally) 
twice this value, or 10% of one-half period, then a power 
black-out condition is sensed, and a power fault signal is pro­
duced.

Patent EP-0273832-A3 (EP)
IPC: G01L13/02
Filed: 1987-12-29
Abstract: A liquid filled differential pressure detector 
comprises two pressure sensors. Each sensor is constructed 
of one or more capsules, which are pairs of diaphragms sealed 
at their periphries. The innermost diaphragms are 
interconnected by a tube which contains a rod assembly. The 
interior of the sensors and interconnection tube form a 
sealed volume filled with a incompressible liquid. The rod 
assembly contacts the outermost diaphragm of the sensors and 
is displaced by expansion and contraction of the capsules 
caused by a differential pressure change against the outer 
surface of the sensors. The motion of the rod assembly is 
transformed into an electrical signal to indicate the 
pressure measurement. The apparatus is symmetrical about the 
center point of the tube to reduce error caused by the 
fluid's thermal expansion by causing equal and opposite 
forces to cancel, thereby preventing motion of the rod 
assembly. An overpressure condition results with one sensor 
completely collapsing with one diaphragm bottoming out 
against the other, but causes no damage to the capsules due 
to complementary facing of the diaphragm pairs. The 
compliance of the diaphragms is chosen to be small enough to 
cause any gaseous bubbles to be driven into solution during 
the initial prepressurization of the fluid, ensuring its 
incompressibility. In a second embodiment, the rod assembly 
is replaced with a core assembly located at the midpoint of 
the tube, suspended in a magnetic fluid which separates the 
incompressible fluid into two identical volumes. The motion 
of the core assembly, which is due purely to the displacement 
of the incompressible fluid, is transformed into an 
electrical signal to indicate a pressure measurement.

Filed: 1988-02-17
Abstract: A child resistant dispensing closure (10) characterized by a closure member (12) and a lid member (14) which is mounted on the closure member (12) for movement between closed and open positions. A peripheral edge of the lid member (14) abuts an annular shoulder (22) provided on the closure member (12) in the closed position, the point of abutment being concealed by an annular ring (24) provided on the closure member (12). In the closed position, thickened portions provided on the peripheral edge of the lid member (14) engage in recesses formed in the annular shoulder (22). The lid member (14) is adapted to be moved upwardly from the closed to an open position when a user applies with one hand a manual compressive force to a panel provided on the exterior skirt (18) of the closure member (12). This manual force results in deformation of the panel inwardly into a slot formed clearly through an enlarged portion of the shoulder (22). As a result, a slight separation occurs between the peripheral edge of the lid member (14) and the shoulder (22) so as to allow the user, with the other hand and while continuing to compress the panel, to engage the peripheral edge of the lid member (14) for moving the lid member (14) to the open position.
