Patent EP-0200357-A3 (EP)
IPC: H02K33/02
Filed: 1986-03-26
Abstract: A non-linear electromagnetic vibration device (20) includ­
ing a first vibration part (6) and a second vibration part (5). A 
non-linear bellows plate spring set (9) is connected between 
the first (6) and second (5) vibrating parts. Each spring set (9) is 
composed of sequentially coupled bellows plate springs (17), and 
each plate spring (17) is elastic according to a predetermined 
particular waveform and has a plate structure of a prede­
termined shape. The waveform is selectable among many in­
cluding portions of an exponential curve. The plate struc­
ture of each spring (17) is rectangular with an edge (fig. 9A-9D) which is 
straight, convex, or concave in contour. The first vibra­
tion part (6) of the device (20) is rigidly connected to a corres­
ponding section of each spring set (9) and the second vibration 
part (5) of the device (20) is coupled to a different or second area 
of each spring set (9). An electromagnetic core (6) and armature (5) 
of an electromagnetic source are respectively included in a 
different one of said first and second vibration parts, and 
stable reciprocating structural components each of a par­
allelogram shaped configuration are formed. Harmonic reso­
nance frequency conversion can be obtained conveniently via 
mechanical adjustment of the number of plate springs (17) in 
each sectionalized waveform plate spring set (9).

Title: Connecting piece for a percutaneous access device
IPC: A61M1/00
Filed: 1986-05-02
Abstract: A removable head is provided for connection to an immovable percutaneous passage device giving access to a fluid circuit in a living organism, a fluid distribution housing and a system comprising this connection head and this fluid distribution housing. Through the connection head of the invention a percutaneous passage, implanted in the blood network of a living organism, can be connected to an apparatus for treating the blood. It comprises a base, screwable on the percutaneous passage, forming a guide cylinder, for a tubular body through which are formed at least two channels. Means for actuating the head impart to the tubular body a translational movement which establishes in turn a direct flow between the channels then places them independently of each other in contact with the organism. The head of the invention further comprises safety devices and is motorizable.
Patent EP-0199669-A3 (EP)
Title: Choke valve especially used in oil and gas wells
IPC: E21B34/04
Filed: 1986-04-11
Abstract: A choke valve especially used for regulating the flow volume and with it the back pressure of liquids or gas while drilling through shallow gas bearing formations from an off-shore drilJing platform comprises a flexible cylindrical valve element (8) positioned in the flow passage of the valve housing (1), the valve being designed such that the valve element's (8) flow area can be reduced by a radial reduction of the valve element. The flow area of the valve element (8) is equal to or larger than the remaining flow area of the valve. The valve has devices (10) for constricting the end of the valve element (8) being nearest to the outlet opening (3) of the valve. The valve element (8) is long enough that it is possible to compensate for the wear, to which the end is exposed, by sliding the valve element against the constricting devices (10) or by moving the latter along the valve element as wear proceeds. Only the valve element (8) is exposed to wear and no other parts of the valve are positioned within the wearing zone. The valve element (8), in its withdrawn position, has its total diameter free allowing a full flow through the valve. Accordingly, the valve does not disturb the flow under normal conditions and is not exposed to any wear. At a gas kick the well can be controlled during a long period as it is possible to compensate the wear on the valve element during operation.

Title: Method of removing electrical shorts and shunts from a thin-film semiconductor device
IPC: H01L27/142
Filed: 1987-11-17
Abstract: A method of removing electrical shorts and shunts from a 
thin-film semiconductor device having pairs of electrodes with 
exposed contact surfaces wherein each pair of electrodes is sepa­
rated by a semiconductor film. The disclosed method comprises 
the steps of coating the exposed contact surfaces with an ionic 
solution and successively applying a reverse-bias voltage between 
the exposed contact surfaces of each pair of electrodes. The 
ionic solution has an etching rate that increases with increased 
temperature so that the leakage current flowing through shorts 
and shunts located between each respective pair of electrodes in 
response to the reverse-bias voltage will create a local tempera­
ture increase at the shorts and shunts and selectively etch or 
oxidize the shorts and shunts, rendering them substantially non­
conductive. The exposed contact surfaces can be coated using a 
sponge applicator or spray apparatus. The preferred ionic solu­
tion comprises an acid mixture diluted to one part in at least 
five parts water.

Title: Controlling responding by users of an intercommunications bus
IPC: G06F13/378
Filed: 1988-11-21
Abstract: Each user of an intercommunication bus is associated 
with a distinct channel of an arbitration bus and 
maintains a priority record indicating its current 
priority status against each other user. During a 
contention interval each user then seeking to use the 
intercommunication bus bids for use of it by 
transmitting a bus request signal and makes an 
analysis of the signals to ascertain if it has a 
dominating priority for initiating a transaction on 
the bus, and access is granted accordingly. During 
the use-signal interval a user then using the 
intercommunication bus transmits an in-use signal 
used to update priority records with the effect of 
giving the last using user lowest priority. For 
transactions which require a response from a user 
other than the one initiating the transaction, a 
second round of bidding is conducted to determine 
whether any user is qualified to respond and if so 
which will be enabled to do so. When the response 
bidding shows no bidders the system immediately 
initiates bidding for a new transaction.

Filed: 1988-12-05
Abstract: The method for driving nails into materials to be connected, the nails being connected by wires or the like to form a band and being able to be formed into a roll of nails spirally in one plane or a flat cone, is characterised by the following features: the nail to be driven in is supplied to the tool head in such a way that it protrudes slightly from the lower end of the tool head, so that, on striking, the nail tip is the first part to come into contact with the material to be connected, the driving-in energy being applied by a striking member which in the process overcomes the action of at least a weak spring urging it away from the nail head, so that it is separated from the nail head in the rest position. The device according to the invention is characterised in that a nail-guiding unit (2) positions the next nail to be driven in in the device in such a way that the nail tip projects beyond the underside of the head (2g), and in that the device has a striking member (1) which strikes the nail head and the striking surface of which is separated from the nail head in the rest position, a spring (4) pushing the striking member away from the nail. <IMAGE>
