Patent EP-0080841-A3 (EP)
Title: Dual coupler fiber optic recirculating memory
IPC: G02B6/28
Filed: 1982-11-18
Abstract: A fiber optic recirculating memory is disclosed which utilizes dual couplers (110, 210) to form a splice-free recirculating memory device from a length of single mode optical fiber (112) forming a loop (140) which acts as a delay line and a second length of single mode optical fiber (130) which provides an input end (132) and an output end (134) for the device. A single signal supplied as an input to the device will result in a series of output signals identical to the input signal, although at smaller, decreasing amplitudes; the invention prevents the first output signal from being substantially larger than the rest of the output signals, thus eliminating the need for protective circuitry on the output end (134) or the rejection of the first output signal. In addition to being useful as a recirculating memory device for use in a system where data is generated at a rate faster than it can be accepted by a data processor, the invention may be used as a tap filter to pass a selected fundamental frequency and its harmonics, and to attenuate all other frequencies.
Patent EP-0095277-A3 (EP)
IPC: G01N33/00
Filed: 1983-05-09
Abstract: The housing 1 of a gas sensor carries a diffusion barrier 
2 for restricting the access of gas to the sensing element 4 
and a filter 3 mounted between the diffusion barrier 2 and the 
sensing element 4. As a result, gas reaching the filter 3 must 
first pass through the diffusion barrier 2 so that its flux is 
substantially reduced and the life of the filter is increased 
correspondingly.

IPC: F24S20/20
Filed: 1983-10-14
Abstract: A tube panel (16) incorporates both vapor generating 
tubes (20) and superheating tubes (30). At least two parallel 
vapor generating tubes (20) are spaced apart to provide a 
gap (40) therebetween. A superheating tube (30) is con­
tiguous with each of the two vapor generating tubes (20) and 
is disposed rearwardly of the gap (40) to span the gap for 
receiving radiation energy (42) from forwardly of the gap to 
ensure a proper distribution of incident heat flux among the 
vapor generating and superheating tubes while eliminating 
the need for complex and expensive vibration support 
members for the vapor generating tubes. A support member 
(48) is disposed rearwardly of and adjacent the superheating 
tube (30) and extends transversely to the longitudinal 
direction thereof, and the vapor generating tubes (20) are 
supported by tie bars (54) connected between the respective 
vapor generating tubes and the respective support member 
to effectively support the superheating tube (30) between the 
vapor generating tubes (20) and the support member (48).

Abstract: A vertical roller mill has a grinding table (1), rollers (3) 
and a separator (6) for separating ground material, which is 
conveyed to the separator in an air stream supplied through 
an inlet (7), into a fine fraction, which passes out through an 
outlet (8), and a coarse fraction which is returned for further 
grinding through an outlet (10). A part of the ground material 
is conveyed through an outlet (11) to a second separator (13), 
where it is separated from the air and returned for further 
grinding via an outlet (14) and an inlet (9) for fresh material to 
the mill. This provides a flatter grain size distribution curve in 
the finish ground material.

Title: Method for electrically connecting non corrodible anodes to the corrodible core of a power supply cable, power supply cable and tubular anode connected to said cable
IPC: C23F13/00
Filed: 1984-06-22
Abstract: The invention relates to an improved method to connect one or more non corrodible, valve metal anodes which surface has been activated by a deposit of non passivatable material, to a power supply cable insulated by a sheath of rubber or other elastomeric material, to make flexible anode assemblies to be used for the cathodic protection of metallic structures, either in water or soil environments.Each anode is provided with a valve metal sleeve, which may be inserted along the cable and then swaged first directly onto the cable's conducting core, previously stripped of its insulating sheath, in correspondence of the central portion of the sleeve, and subsequently swaged at the two ends directly onto the insulating sheath of the cable.Bushes of a ductile metal or alloy, preferably anodically dissoluble, are disposed onto the valve metal sleeve before swaging, in order to take up the wrinkling and allow a more uniform circumferential reduction of the valve metal sleeve over the cable.

Patent EP-0123563-A3 (EP)
IPC: H03M5/06
Filed: 1984-04-26
Abstract: A converted digital signal is provided in NRZI code with 
a dc component of zero and with a maximum number of four 
bits between level transitions in the signal. The base digital 
signal is divided into 8-bit base words, each of which is then 
converted into a 10-bit converted word to form a converted 
digital signal suitable for recording. Of the 1024 (2¹⁰) possible 
10-bit combinations, there are 193 that begin with no more 
than two digital zeros, end with no more than one digital 
zero, have no more than three consecutive digital zeros 
anywhere else and have a dc component of zero when 
NRZI-coded. Each of these 193 primary 10-bit combinations 
is used to represent one 8-bit base word. Each remaining 63 
of the total 256 (2⁸) base words is converted into a secondary 
10-bit combination which has a "convention" dc component 
of +2 or -2, defined as the dc component when the 
combination is NRZI-coded and the preceding combination 
ends at the signal's lower level, but which otherwise meets 
the description of the 193 primary 10-bit combinations. 
Beginning with the first bit of one secondary combination, 
the number of level transitions in the converted digital 
signal, when NRZI- coded, are detected up to the end of the 
10-bit combination immediately preceding the next secon­
dary combination. Depending on the number of level 
changes, the first bit of the next secondary combination is 
provided to give that secondary combination a convention 
dc component which eliminates the actual dc component in 
the portion of the signal containing the pair of secondary 
combinations.

photosensor and renders the sound reproductive system 
operative.

Abstract: A power supply system has a primary power source S1 
which is energized from the mains, and a secondary power 
source S2 which is a battery and which is to be switched in 
automatically when the mains power fails, to supply a load 
L. The two power supplies are connected to the load by 
means of the emitter-collector paths of two respective tran­
sistors Q1 and Q2. The two transistors have a common base 
resistor R. Whichever power supply produces the higher volt­
age turns its transistor on and the other off. This circuit in­
volves relatively low voltage drops (compared e.g. to the use 
of steering diodes), and is therefore suitable for low voltage 
supplies, e.g. 3 V.
