Patent EP-0077306-A3 (EP)
IPC: H02K7/20
Filed: 1982-09-23
Abstract: The present invention relates to a rotating, also selfworking 
device for the production of costless electric energy being 
composed of a preferably direct current electric motor (5), which, 
by means of interposed gears (2 and 4) idly mounted on a fixed 
casing, causes the operation of the power shaft of a generator (7) 
which is able to supply electric energy to possible utilizers and 
also to give back to said motor a quantity of energy sufficient to 
allow it to work, upon its transformation into direct current by 
means of an appropriate transformer-commuter-chopper (11), 
the starting of said device being assured by a storage battery (10) 
which supplies said motor.
Patent EP-0105490-A3 (EP)
IPC: G06F3/153
Filed: 1983-09-29
Abstract: A font display and text editing system 10 is disclosed. 
The system includes a display medium 40 for displaying text 
characters. A memory 24 stores digital information describ­
ing the shape of each alphabetical character of a plurality of 
sets of alphabetical characters, each of the set of alphabetical 
characters defining a respective font. An input device 38 
sequentially generates a first signal identifying one of the 
alphabetical characters as a base character and a second 
signal identifying a different one of the alphabetic characters 
as an overlay character. A circuit 11-22 and 26-36 responsive 
to the signals displays the base and overlay characters as a 
single complex character on the display medium.

Title: Ink jet printer
IPC: B41J2/005
Filed: 1984-03-19
Abstract: A method is proposed for fabricating components of an ink droplet generator for generating a sequence of charged, detected and deflected ink droplets for an ink jet printer, as is proposed an ink droplet generator fabricated thereby. The method which is based upon multi-layer technology involves forming the charging electrodes and the detection electrodes by removing unnecessary metal coating from a support element metallically coated on at least one side of the support element and forming the deflection electrodes by removing unnecessary metal coating from a polyimide foil coated on at least one side thereof. The polyimide foil is mounted on a substrate constructed as a support element. The arrangement defining the ink droplet generator comprises a first module formed from both board or panel-like support elements and a second module formed from both board or panel-like support elements.
Patent EP-0138039-A3 (EP)
Title: Electrical termination block for flat conductor cable
IPC: H01R12/59
Filed: 1984-09-06
Abstract: A tansition block connector serves as a fastening point 
for a plurality of terminal screws which extend through 
holes in the spaced-apart conductors of a flat flexible cable. 
To provide fastening points for the spaced-apart screws, 
and to accomodate variations in the spacing between them, 
mating fasteners are moveably mounted in a housing which 
is formed of electrically insulating material. The moveable 
mounting includes a recess in the housing for each fastener 
which has internal dimensions larger than the external di­
mensions of the fastener, and a portion of the fastener has 
a non-circular exterior configuration which cooperates with 
a portion of the recess having a non circular configuration 
to prevent rotation of the fastener within the recess while 
permitting lateral displacement of the fastener relative to 
the housing. The housing is formed in two parts which define 
an internal shoulder which in turn cooperates with an exter­
nal shoulder on the fastener to prevent withdrawal of the 
fastener from the recess when the two parts of the housing 
are joined together. A conductive support plate coupled to 
the housing includes an electromechanically coupled 
threaded fastener which cooperates with a through opening 
in the housing to permit coupling of a conductor of a flat 
cable directly to the support sheet for grounding purposes.

IPC: G01D5/20
Filed: 1985-06-12
Abstract: A method and apparatus for producing a color strip 
display (18) of eddy current test data from a test signal 
produced by an eddy current detector (1) which varies in 
amplitude and in phase relative to a reference signal as the 
detector (1) is displaced along a test body. To produce the 
display (18), signals representative of the relative displace­
ment of the detector (1), signals representative of the 
amplitude o the detector signal, and signals representative of 
the relative phase shift of the detector signal from the 
reference signal are produced, for elected frequencies. The 
representative signals are processed and transmitted to a 
color display device (15) for producing a strip display (18) of 
the signal at each selected frequency. The single composite 
display produced for each frequency represents the relative 
displacement of the detector (1) along the body (2), the 
amplitude of the detector signal, and the relative phase of the 
detector signal depicted by a colored trace of the signal peak, 
the hue of which corresponds to the depth of the fault.

Title: Games racket
IPC: B29K105/12
Filed: 1985-06-24
Abstract: The invention relates to a hollow racket frame, e.g. for tennis, made by injection moulding of reinforced thermoplastics material. The frame has a head and handle portions and pairs of integrally-formed stringing holes (26, 27) are in the outer circumference (23) and are in the inner circumference (22) of the head respectively. Each stringing hole is defined by an integrally-moulded reinforcing tubular projection (24, 25) projecting inwardly of the hollow frame. The two opposed projections are of insufficient length to meet inside the hollow frame. The integrally-formed holes and tubular projections are made using suitably shaped mould pins (15) passing through holes in a fusible mould core (10) around which the thermoplastics material is injected. Pins (15) are a tight fit in their holes for the centrai portion of their lenght which provides positive location during moulding.
