Title: Device for eliminating hydrogen
IPC: C01B5/00
Filed: 1987-02-07
Abstract: An arrangement for the elimination or removal of hydrogen from a hydrogen-containing gas mixture through the intermediary of foils which are fastened within a closable container, wherein the material of the foils produces an elimination of hydrogen, whereby the foils are so arranged at such spacings with respect to each other as to form interspaces between the foils which can be streamed through by the gas mixture. At least one supporting member having the foils adhering thereto is arranged within the container in such a manner that the foils will extend into the surroundings upon opening of the container. Especially suitable for this purpose are spirally-wound supporting members which will extend out of the container under the effect of gravity or under the action of a mechanical spring force, and in this manner provide a direct contact between the effective foil material and the explosively dangerous gas mixture.

IPC: H01L21/316
Filed: 1987-07-03
Abstract: A multiple recess isolation technology avoids 
stress induced defects while providing a substantially 
planar surface. A silicon substrate (10) is patterned and 
etched, creating active moat regions (18) and recesses 
(20a-b and 21a-b). The recesses are filled with oxide by 
growing a field oxide (40) in wide recessed regions (21) 
using a LOCOS process, while depositing a planarization 
field oxide (44) in narrow recessed regions (20). After 
etching the structure to obtain a planar surface, standard 
procedures are used to fabricate the active devices. The 
process uses a single photolithographic masking step and 
results in only a very small loss of the width 
electrically active regions.

IPC: B62K3/02
Filed: 1987-07-06
Abstract: There is provided a bicycle frame, particularly one cast in a 
lightweight alloy or metal such as magnesium, characterised in 
that a mounting for a chain guide sprocket for a rear derailleur 
comprises a bracket 22 adapted to receive the guide sprocket 
mechanism in a threaded hole 28, and pivotally mounted on the 
frame so as to pivot rearwards as indicated in dashed lines from 
its normal position of use to create a clearance for the removal 
of a rear wheel mounted by means of a spindle in a slot l3. 
Preferably the bracket 22 is made of a plastics material which is 
less structurally strong than the metal of the frame, so that the 
bracket 22 will snap preferentially or sacrificially in the event 
of an impact, so that the frame itself will not be damaged, and 
the bracket 22 merely needs to be replaced. The bracket 22 may 
be somewhat yielding so as to absorb light impacts prior to 
fracture. The bracket 22 may be pivoted onto the frame by means 
of a snap-in pin 23.

invention is particularly suited to securing replaceable 
segments on a rotary work member and also has particular 
utility in the textile field for connecting staves to a 
base roller or the like.

Patent EP-0289051-A3 (EP)
IPC: H04N5/85
Filed: 1988-04-29
Abstract: In a recording system operable in response to a 
sequence of image signals to record a sequence of 
recording signals on a main image recording medium, 
efficient coding is carried out by the use of parameters 
which are adaptively changed from one to another through 
a parameter controller (35) acting as a man-machine 
interactive device. The image signals are repeatedly 
given to the recording system to be subjected to the 
efficient coding with reference to a sequence of 
predictive value signals V(i). The predictive value 
signals are displayed on a monitor display device (37) 
to be monitored by an operator. The operator can change 
the parameters from one to another until an optimum 
image is displayed by the use of optimum parameters, 
watching the display device. The optimum parameters are 
sent on a magnetic tape (36). The image signals are 
subjected to the efficient coding into a sequence of 
coded image signals which are recorded on the main image 
recording medium in synchronism with the optimum 
parameters after the optimum image is obtained.

Abstract: A position coupler for connecting reinforcing bar in concrete 
construction where neither bar is able to rotate either conveniently or not 
at all includes a sleeve (17) at least a portion of which is internally 
cylindrically threaded and which receives at least one split collar insert (18). 
The insert has external cylindrical threads (27) which match the internal 
cylindrical threads (28) of the sleeve and also has internal tapered threads 
(31) which match the tapered external threads (45) on the bars (42, 43) to be 
joined. The inserts, in addition to being longitudinally split are provided 
with either a transverse slot (39) or a hex head (122) on their outer ends to 
receive a wrench. When a transverse slot (39) is provided a spanner wrench 
(49) may be inserted between the bar and sleeve. The tightening of the 
insert creates a wedge action which hoop stresses the sleeve locking the 
parts together and reduces slippage. The insert may be locked anywhere 
along the interior of the cylindrical thread portion of the sleeve to connect 
bars at different axial spacings. In a preferred form the sleeve (17) is 
machined from stock with the cylindrical threads (22) receiving the insert 
being formed on one end while the opposite end is provided with a taper 
thread socket having taper threads which match the external tapered 
threads (44, 45) of the bars to be joined. In another embodiment the sleeve 
is formed of tube with the internal cylindrical threads extending the length 
of the sleeve and an insert for each bar is employed. The sleeve may be 
provided with opposite hand threads (71, 72) so that rotation of the sleeve 
will draw the rods together before the inserts are fully torqued and locked.

Foucault dans le tube (5). La diminution de la sensibi­
lité due à l'augmentation de la résistivité du tube (5) 
avec l'augmentation de la température est compensée par 
l'augmentation de la sensibilité due à l'augmentation de 
la perméabilité de la tige (4) avec l'augmentation de la 
température. Le détecteur est de faible poids et encom­
brement et il est compensé en température dans une plage 
comprise entre - 40°C et + 250°C.
