Patent EP-0234455-A3 (EP)
IPC: G02B6/02
Filed: 1987-02-13
Abstract: Disclosed is BeF₂-based optical fiber. Such 
fiber can have, in addition to low loss, other 
advantageous properties. For instance, BeF₂-based 
dispersion shifted single mode fiber can have lower 
core-cladding index difference and larger core diameter 
than the corresponding SiO₂-based fiber, and BeF₂-based 
graded index multimode fiber can have larger bandwidth 
than the corresponding SiO₂-based fiber. The inventive 
fibers have a core and a cladding containing at least 
30 mol% BeF₂, and may contain up to 40 mol% of AlF₃, and 
one or more members of the group consisting of NaF, KF, 
MgF₂, CaF₂, PbF₂, PF₅, and SiF₄. An exemplary and 
currently preferred glass has nominal composition (in 
mol percent) 30KF-(l5-x)CaF₂-xPbF₂-l0AlF₃-45BeF₂ with 
x 
</= 
 l5. Single mode fibers according to the invention 
have minimum total dispersion in the range l.5-2.0 µm, 
and typically have 0.25% 
</= Δ esi  
</= 0.6%, and 
2.5 µm 
</= 
 a esi  
</= 3.4 µm, where Δ esi  and a esi  are the 
equivalent step index core-cladding index difference and 
core radius, respectively. Rules and techniques that 
can advantageously be used to design BeF₂-based single 
mode fibers are also disclosed.

Patent EP-0389673-A3 (EP)
IPC: H01P1/11
Filed: 1989-09-14
Abstract: A reciprocal transceiver to radiator coupling 
circuit uses both microstrip and waveguide modes of 
RF signal transmission (including a pair of 
nonreciprocal hybrid mode phase shifters) to gain 
size and weight advantages useful in feeding large 
scale phase arrays. At the same time, the radar 
cross section of such array apertures is reduced by 
arranging separate nonreciprocal receive and transmit 
branches of the circuit to route spurious 
intra-circuit reflections of incoming RF signals to a 
matched termination.

Title: Digital modulator
IPC: H04L27/20
Filed: 1989-01-19
Abstract: Signal modulation apparatus for the transmission of binary data 
signals embodying a process which results in superior side-lobe 
suppression compared with other forms of modulation such as frequency 
shift keying. The apparatus generates two carrier waves, the 
difference between whose frequencies is an integral multiple of the 
data signal bit-rate, amplitude modulates the two waves by a low-pass 
filtered data signal and an inverted version thereof respectively and 
then sums the resulting modulated waveforms to produce a frequency 
keyed waveform having continuous phase and almost negligible envelope 
ripple. The apparatus can be used with most forms of digital 
communication systems and may be demudulated by a conventional 
receiver such as ratio detector or phase-locked loop.

Title: Transformation of divisor and dividend in digital division
IPC: G06F7/507
Filed: 1989-07-14
Abstract: A method of and means for adjusting the divisor 
and dividend, for application to a divider, so that the 
divisor is transformed to be within a known limited 
range. The limiting of the transformed divisor range 
enables the complexity of the quotient select logic to 
be reduced accordingly. Once the divisor is restricted 
to the selected range, the dividend is adjusted 
proportionally so the quotient is unchanged.

Abstract: A radio telephone apparatus comprising a main 
station (1) connected to a wire telephone line (3) and having 
a subsidiary telephone set (28), and a radio telephone set (2) 
connected with the main station (1) via a radio circuit, 
wherein the radio telephone set (2) effectively or 
ineffectively controls a function of releasing the hold state 
by the off-hook operation of the subsidiary telephone set (2). 
By the operation of the radio telephone set (2), telephone 
communication can be switched between a self-hold state and a 
complete hold state. The self-hold state can be released only 
by the radio telephone set (2) while the complete state hold 
can be released by any one of the radio telephone set (2) and 
the subsidiary telephone set (28). In the complete hold 
state, the radio circuit between the main station (1) and the 
radio telephone set (2) is disconnected. If the complete hold 
state is released by the radio telephone set (2), the radio 
circuit is again established between the main station (1) and 
the radio telephone set (2).

Patent EP-0386467-A3 (EP)
IPC: H04N5/782
Filed: 1990-02-03
Abstract: To simplify the preprogramming of receivers, particularly of video recorders, taking into consideration timeshifts in the programme contribution concerned, it is known to generate additional information items such as programme source information, day of the week, start time and end time at the transmitting end, which are transmitted together with the television signal. These additional information items are also contained in the programme tables of a teletext signal and can be input into a memory of the receiver on command. When the transmission is shifted, for example by one "VPS day" or more, a further additional information item is generated at the transmitting end, by means of which updating, in particular correction, of additional information items already stored in the receiver is made possible. The novel method can also be used for controlling receivers which only contain a VPS decoder for decoding the additional information items. <IMAGE>

Title: Radiation activated hydrosilation reaction
IPC: A61K6/90
Filed: 1990-05-17
Abstract: This invention relates to a hydrosilation process involving 
the reaction of a compound containing silicon-bonded 
hydrogen with a compound containing aliphatic unsaturation 
in the presence of actinic radiation. While there are 
catalyst systems that provide an alternative to ultraviolet 
initiated hydrosilation, several limitations of these 
systems can be cited. First, the systems require both a 
visible light absorbing sensitizer and a stable ultraviolet 
absorbing photohydrosilation catalyst, for example, an 
(η⁵-cyclopentadienyl)trialkylplatinum complex. Second, 
relatively high concentrations of the platinum catalyst, up 
to 1000 ppm platinum, are sometimes essential for rapid 
cure. Third, these systems have a limited depth of cure. 
Finally, these systems have only a moderately long 
shelf-life at room temperature. This invention provides a 
process for the actinic radiation-activated addition 
reaction of a compound containing silicon-bonded hydrogen 
with a compound containing aliphatic unsaturation, said 
addition being referred to as hydrosilation, comprising 
using, as a platinum hydrosilation catalyst, a complex 
represented by the formula: 
   
     wherein R¹ and R² independently represent hydrogen, an 
alkyl group, or an aryl group, R³, R⁴, R⁵, and R⁶ 
independently represent an alkyl group, an aryl group, or 
an alkoxy group. The invention also provides novel 
compositions, capable of undergoing hydrosilation, 
containing the platinum complexes disclosed herein. 
An important application of the process and compositions of 
the invention is as a visible light curable impression 
material for dental applications.
