Patent EP-0352758-A3 (EP)
IPC: H03K17/95
Filed: 1989-07-25
Abstract: The invention relates to a method for detecting rapid 
damping changes in the oscillator input circuit of a 
proximity switch. A high-frequency oscillation gener­
ated by the oscillator and amplitude-modulated by the 
damping changes is demodulated such that a demodulated 
signal voltage which fluctuates with the frequency of 
the damping changes is obtained. This signal voltage is 
amplified as ac voltage and the amplified signal vol­
tage is converted by means of threshold switching de­
vices to a pulse sequence with a pulse sequence fre­
quency which corresponds to the frequency of the vol­
tage changes in the signal voltage.
Patent EP-0354589-A3 (EP)
Title: Coin analyzer system and apparatus
IPC: G07D5/08
Filed: 1989-08-12
Abstract: A coin analyzer system and apparatus that 
provides a detection circuit for comparing a tested 
coin with at least two different sample coins. Two 
different sample coins are located in a magnetic 
field, and the tested coins pass through another 
region of the magnetic field. In the event the 
tested coin does not match either sample coin, a 
rejecting gate forces the tested coin out of the coin 
chute in a laterally normal direction and into a 
rejected coin chute. In the event that the tested 
coin matches either sample coin, the rejecting gate 
is opened and the tested coin drops through a 
substantially vertical accepted coin chute. Credit 
is not extended the tested coin until the coin passes 
a confirmation sensor, and the determining circuit 
may be adjusted to vary the credit value extended to 
at least one of the sample coins. A lockout circuit 
rejects and prevents a subsequent coin from being 
analyzed during the time that the circuit is 
crediting a prior tested coin with multiple credits.

Title: Food product packaging
IPC: B65D25/16
Filed: 1989-11-07
Abstract: A food product 12, for example a filled dough 
product, is baked in a container 10 closed by a web 14 
of controlled-porosity paper or plastics. After baking 
and before or after cooling, the closed container is 
subjected to an inert-gas atmosphere for 60 to 90s, 
during which time oxygen in the container is replaced 
by inert gas to extent sufficient to prevent subsequent 
deterioration of the product. To this point, the 
controlled-porosity paper acts as a barrier to entry 
into the container of micro-organisms which would cause 
deterioration of the product. After treatment with 
inert gas, the container is packaged in a gas-­
impermeable envelope. The cooking, gas-treatment and 
packaging steps may be carried out on products 
continuously conveyed on a conveyor belt.

Title: R. f. switching circuits
IPC: H01L29/423
Filed: 1989-12-04
Abstract: An advanced MESFET switching structure includes an 
interdigitated source region (48a, 48b) and an interdigitated drain 
region (46a, 46b, 46c), and a gate electrode region disposed between 
adjacent portions of the interdigitated source and drain regions 
having a series gate electrode (47a-47d) in Schottky barrier 
contact therewith. The use of the series connect gate electrode 
(47a-47d) rather than conventional parallel coupled gate fingers 
eliminates the need for airbridge overlays to interconnect the 
source regions as in a conventional MESFET transducer. Moreover, 
the topography permits smaller MESFET structures and thus higher 
integration of circuits employing the advanced MESFET switch 
structure. The smaller transistors have lower parasitic reactances. 
All interconnections (46, 47e, 47f, 47h, 47i, 48) for drain, gate, 
and source electrodes are disposed on the active layer portion (44a) 
of the transistor providing an even smaller transistor structure.

Patent EP-0427354-A3 (EP)
Title: Apparatus for introducing a cable into a cable guide tube
IPC: G02B6/50
Filed: 1988-04-26
Abstract: Apparatus for installing cables with a certain stiffness, more in particular glass fibre cables, into a duct (6, 24) of a channelization system, using the working of a compressed gas, which apparatus is adapted to exert pushing forces on a cable (26) being introduced in order to support the compressed gas working on the cable in the duct. The apparatus comprises cable advancing means and gas inserting means. The cable advancing means include a hollow, substantially rectilinear cable lead-through channel (3) with an entrance end (4) and an exit end (5), at least one pair of wheels (8, 10; 9, 11) mounted opposite to each other for moving on a cable (26) disposed between these wheels into the direction of the outlet end (21) of the duct (6), and a pneumatic motor (15) coupled to at least one of said wheels for providing a driving couple to it. At least one of the wheels is coupled to a pneumatic piston/cylinder combination (13, 14), in such a way that when compressed gas is supplied to the pneumatic cylinder (14), transverse forces will be exerted on the cable (26) disposed between the wheels (8, 10; 9, 11). The gas inserting means include a gas channel (7), which debouches into the cable lead-through channel (3) and which is adapted for inserting compressed gas into the lead-through channel (3) between the wheels and the exit end (5) of the lead-through channel (3). The motor (15) is capable of providing a driving couple, which is larger than the driving couple, which has to act on the cable (26) to compensate a pressure difference existing at the inlet end of the duct between the pressure inside and the pressure outside the cable lead-through channel (3) as a consequence of inserting the compressed gas via the gas channel (7) into the cable lead-through channel (3). The pushing forces are exerted by the wheels on the cable (26) as a consequence of the cooperative effect of the driving couple and the transverse forces. The gas channel (7), the pneumatic motor (15) and the piston/cylinder combination may be coupled to the same compressor. For use in a tandem arrangement the apparatus comprises further a coupling unit (18) to be coupled to an outlet end (21) of a preceding duct section (24), and which includes a mainly hollow housing (19), an outlet pipe (23) for diverting a flow of gas, which may leave the outlet end (21) of the duct section (24), and an outlet opening (22) through which a cable may be led into the direction of the entrance end (4) of the cable lead-through channel (3). Advantages: the exerted transverse forces are very acurately adjustable and substantially constant; the apparatus is non-destructive to the cable when cable introduction is slowing down or stagnates; in a tandem arrangement the apparatus needs hardly any human interference and is safe for the operating staff. <IMAGE>
