Patent EP-0282932-A3 (EP)
Title: Frequency-modulated track current circuit
IPC: B61L1/18
Filed: 1988-03-12
Abstract: A circuit is described in which the bandwidth of the track circuit receiver (8) is design to be so narrow that it is virtually impossible for it to be subjected to interference. To permit interpretation of the frequency-modulated track voltage, the frequency deviation of which far exceeds the bandwidth of the receiver, the narrow band characteristic is achieved by means of an adjustable bandpass filter (7), the centre frequency of which is controlled so that it precisely follows the frequency of the track circuit transmitter (2). For this purpose, the output signal from the track circuit transmitter is fed to the track circuit receiver via a special lead (9). <IMAGE>

Title: Seal device for a container and containers thus obtained
IPC: B65D51/22
Filed: 1988-07-28
Abstract: The proposed seal device comprises a capsule (1) and a container 
insert (11). The insert (11) ends in a hole sealed by a membrane 
(13) having a thinner joining edge (14a) so as to be breakable and 
equipped in the centre with a first engaging means. The capsule 
(11) is equipped with a second engaging means matching the first, 
facing towards the first and having in its lower part a cutting 
surface (6) facing the breakable joining edge (14a) of said 
membrane (13). The capsule (1) preferably has a band (9) at its 
lower end attached with small breakable ribs, forming an outer 
guarantee seal, limiting the movement of the capsule (1) when the 
product is new, so as to prevent the membrane (13) from being 
broken.

Title: Damping spacer for bundle conductors of high voltage overhead electric lines with optic fibres cable inside the bundle
IPC: H02G7/14
Filed: 1988-08-30
Abstract: The present invention concerns a damping spacer for bundle con­
ductors of high voltage overhead electric lines, particularly for a 
bundle of electric sub-conductors inside which there is positioned an 
optic fibres cable. The spacer comprises a stiff body, onto which there 
are hinged a plurality of support arms, each through a springing hinge, 
to the end of each arm there being associated a clamp for connection and 
anchorage to each sub-conductor of the bundle. The stiff body has a 
nonsymmetrical configuration, eccentric in respect of the central axis of 
the bundle of conductors, which leaves free the central zone of the 
bundle. The stiff body also carries at the centre a hinge for a 
supplementary rocking arm, the end of which projects towards said central 
zone of the bundle and carries a connection clamp for an optic fibres 
cable.

Title: Catalytic gas calorimeter systems and methods
IPC: G01N25/30
Filed: 1988-08-16
Abstract: A novel catalytic gas calorimeter system and 
method. The system comprises a catalytic reactor 
which includes a catalyst capable of oxidizing the 
sample gas. The catalyst is configured within the 
reactor so as to maximize the catalyst surface area 
available to the sample gas, such as, for example, by 
depositing the catalyst on a bed of small beads of 
porous surface structure or on a porous monolithic 
substrate. The reactor temperature and space 
velocities are maintained at a level which will ensure 
substantially complete oxidation of the sample gas.  
     The catalytic reactor of the present invention is 
surrounded by one or more temperature shields to 
isolate the reactor from the surrounding environment. 
A sensor device is positioned within the reactor to 
measure the temperature within the reactor. The 
calorimeter system also includes means for measuring 
and controlling the volume of gas and air entering the 
catalytic reactor and means for measuring the relative 
humidity of the gas stream leaving the catalytic 
reactor. These measurements are then used to 
calculate the net heating value (NHV), gross heating 
value (GHV) and the specific gravity of the sample gas 
under consideration.

drawbar (32) and disposable within the vessel portion to be tested. Also, the 
deformable member is located between the sleeve outer end (38) and the 
drawbar outer end (46) such that movement of the drawbar relative to the 
sleeve causes the respective pressure-generating and pressure-releasing 
radial expansion and contraction of the deformable member.
