Patent DE-3900351-A1 (DE)
Title: Lens hood (lens shade), having a variable angular field and being format-related, for sliding variable-focus lenses, having synchronous wing adjustment corresponding to the focal length
Inventor: GEGGERLE SIGMUND DR
IPC: G03B11/04
Filed: 1989-01-07
Abstract: To obtain a lens hood which fits precisely for each desired and possible angular field of a variable-focus lens it is necessary to correspond to the angular field of the respectively used focal length in that the four wings of the lens hood assume a fitting angular position in that they are suspended on a telescope-like linkage, the possibility of movement is produced with the aid of hinges, and this linkage is correspondingly controlled by a pin which engages in a guiding curve (leading curve) accommodated in a carrier, which then leads to the respectively desired angular position of the wings. This can also be achieved by means of an electric motor, without carriers, pins and guiding curve.

Title: Method and device for tensioning a screen-printing frame
Inventor: PLOETSCHER KLAUS
IPC: B41F15/36
Filed: 1989-04-03
Abstract: A device (1) serves for pretensioning screen-printing frames (2), their frame limbs (4) being deformed and prestressed elastically inwards. For this purpose, the device (1) has tension arms (13) with claws (14) located at the free ends for hooking into the frame limbs (4). By applying tension to the tension arms (13), the frame limbs (4) are then drawn inwards and, during this process, are slightly elastically deformed. In this case, the deformation force corresponds approximately to the prestressing force of a printing fabric (3) to be connected to the frame (2), such that, when the fabric tension is transferred to the respective frame (2), no further deformation of the frame occurs and the fabric tension is thus maintained (Figure 5). <IMAGE>

Title: Cranioplastic bone replacement - by using specified fibre mat cutting and specified plastic implant
Inventor: PEIXOTO JOSE-MILTON
IPC: A61L27/16
Filed: 1989-07-14
Abstract: An infected or defective trepanned bone of the skull is replaced by an implant of plastic material (PMM). A flexible silicone fibre burl mat is cut to the size of the trephined area and a layer of plastice is applied to permit the points of the burl to penetrate the layer. After hardening in situ the implant is separated from the mat and the contours of the implant are moulded to the trephined area. ADVANTAGE - This requires no special formation of fine holes (needed for elution of the antibiotics used and for better perfusion) and minimises the final trimming.

Title: Ultrasonically sealing packages in film - machine draws plastic film over top front and bottom of packages, presses film round rear and underside, and applies sonotrode underneath
Inventor: LUEDTKE PETER
IPC: B65B51/22
Filed: 1989-09-07
Abstract: Plastic packaging films are ultrasonically welded in binding round or sealing packages or stacks longitudinally in reference to their direction of movement; in the process the packages/stacks are passed through a curtain of the film so that they are covered on three sides, and a strip of the curtain is projected so as to cover the fourth side behind the package/stack. A device takes a loop of the curtain over an ultrasonic welding head to a cutter.

Patent DE-3930165-A1 (DE)
Title: Parallel data compression for testing, esp. in computer structures - using signature method with input and output data association devices for signature register
Inventor: STOPP ANDREAS DR ING
IPC: G06F11/277
Filed: 1989-09-09
Abstract: The method of parallel data compression involves processing multiple bit width input data vectors (A) in parallel during one clock cycle. Signature processing logic is used to implement the algorithm system for multiple step serial signature registers. The clock step width is greater than or equal to the input data width and the characteristic polynomial of degree 1 is irreducible and prime. An input data associator (1) switches the input bits to lines which are connected to the signature register (2) inputs via two antivalance gates. The register outputs are single bit output or signature vectors which are fed back to thee antivalance gates. The input data associator and an output data associator (4) are switchable (S1,S2) between signature and generator mode and control and observation mode states. ADVANTAGE - Ensures high probability of fault location during testing of integrated circuits at low component cost and with reduced testing time.

Title: Biological waste-water treatment plant - by adsorption process, in which performance is improved by addition of final denitrification filtration stage
Inventor: BOEHNKE BOTHO PROF DR ING DR
IPC: C02F3/30
Filed: 1989-10-06
Abstract: Biologically activated back-flushing de-nitrification filter, for an-oxygenic operation, is downstream of the biologically intensified filtration stage in a biological adsorption waste water treatment plant. The sludge handling system incorporates a heated prepn. device for part (approx. 20%) of the sludge flowing from the adsorption tank, and the treated sludge is supplied as an organic material feed into the de-nitrification filter via a sieving stage and a pipe system. The denitrification filter opt. contains an activated carbon filtration material, and the heated sludge prepn. device may incorporate an autoclave. USE/ADVANTAGE - Used in the design of biological water treatment plants which operate by means of an adsorption process. The proposed system reduces the space and ground area, which is normally considerable, occupied by the plant in an economical manner, and to a large extent eliminates the micro-impurities of the prod. water - i.e. the organic and partly poisonous substances which normally exist in small concns. in the water leaving treatment plants of this type.
Patent DE-3934826-A1 (DE)
Title: Processing nuclear pebble pile elements - by crushing and adding to steel melt
IPC: G21C19/44
Filed: 1989-10-19
Abstract: Spherical pellets used for fuel or absorber/moderator elements of pellet pile reactors consist of graphite or silicon carbide with a nucleonic admixture of uranium and thorium having a radioactivity depending on whether they are virgin elements or have been irradiated.  They are crushed and passed in a steel melt where graphite or SiC are absorbed by the melt and the nucleonic additives are extracted in the gas phase and separated from the gas. The reactor elements should be crushed to the millimetre range. After absorption of the graphite or silicon the melt can be refined by an oxygen blast.  The outgoing gases are purified and freed from radioactive constituents. ADVANTAGE - This is simpler than conventional chemical processes and produces compact radioactive waste requiring little space for final deposition.

Patent DE-4001225-A1 (DE)
Title: Magnetic reading head
Inventor: NEGISHI KENJI
IPC: G11B5/187
Filed: 1990-01-17
Abstract: A magnetic reading head has a controller with a surface (33) placed opposite to the recording surface of a magnetic disc (13) or a reading head mounting (21) for producing a vacuum between the controller and the magnetic reading head, in order to draw the rotating magnetic disc and the magnetic reading head together, producing an adequate, satisfactory vacuum in the vicinity of the magnetic reading head and a good contact with it.  This appts. offers a compact mechanism and an enlarged recording surface on the magnetic disc, compared with other appts. which use a magnetic reading head and stabilising disc separately to produce a vacuum to draw the magnetic disc to the magnetic reading head. It also removes the need for a series of operations to position the single reading head and the stabilising disc separately, which considerably reduces manufacturing processes and production costs.

Title: Automatic station selection process for RDS preselect receiver - using stored list of alternative network frequencies to initiate follow-up tuning sequence if required
Inventor: MIYANO KOICHI
IPC: H04B1/16
Filed: 1990-12-07
Abstract: The multiplied Radio Data System (RDS) transmission signal contains blocks of digital information data; i.e. programme identification data (PI) and lists of alternative network frequencies (AF data). Selection of a pre-select station by the receiver initiates an audio-mute tuning process which ends when an RDS station is found whose transmission strength achieves a preset level and whose programme identification data (PI) matches that of the preselected station. - If the RDS receiver fails to achieve selection of the desired station an automatic follow-up sequence selects an alternative transmitter frequency from the receivers stored list (AF data) of networks broadcasting the same programme.
