Title: Hand-wheel adjustment for offset printing press - has coupling between worm and hand-wheel giving limited free movement within which motor-reversing switch is actuated
Inventor: BLASER PETER THEOBALD
IPC: B41F13/14
Filed: 1992-03-17
Abstract: The hand adjustment is for the angular position of the press cylinders, using the driving electric motor to turn a rotary component of the driving mechanism. This component (1) is coupled to the worm wheel (7) of a worm gear (7, 8). The worm in turn is coupled by a selector (11-14) to the handwheel (4), so as to allow some angular free movement. During this free movement, the direction of rotation of the handwheel causes a switch (15) to operate selecting the direction fo rotation of the motor, and switching the latter on. USE/ADVANTAGE - Offset printing press adjustment gives angular adjustment by motor analogous to handwheel angle and dependent on speed of handwheel.

Title: Alpha-silicon nitride filament prodn. with larger aspect ratio than whisker - by reacting volatile silane with ammonia in hydrogen over transition metal catalyst, giving quasi-mono-crystalline filament
IPC: C04B35/591
Filed: 1992-06-17
Abstract: In the prodn. of alpha-Si3N4 filaments (I) with length/dia. (L/D) ratio greater than that of whiskers, by reacting volatile SiHx cpds. (II) with NH3 in an atmos. contg. H2, a transition metal (III) is used as catalyst. Pref. (II) are produced in situ from H2 and metallic Si. (III) is Fe, pref. in granular form or with nucleation points produced by structurising the surface. USE/ADVANTAGE - The (I) obtd. have a greater L/D ratio than carcinogenic whiskers and are quasi-monocrystalline. In this way, they differ from continuous fibres made by thermal degradation of inorg. polymers, which are amorphous or polycrystalline and hence not strong enough for long-term use as reinforcement, in e.g. ceramics for high temp. applications. (I) of cm-length can be grown.

Title: Field effect transistor mfr., e.g. for MESFET or HEMT prodn. - applying mask on gate region active semiconductor layer and forming ohmic contact in second step between semiconductor layer and metallising material
Inventor: RISTOW DIETRICH DR
IPC: H01L21/265
Filed: 1992-06-17
Abstract: The mask (2) has apertures in source gate, and drain regions. The ohmic contact between the semiconductor layer (4) and the suitable metallising material is formed in anisotropic manner in oblique impingement direction. In the two mfg. steps, the mask thickness and the impingement angle are chosen such that the ohmic contact material does not reach the mask gate aperture. In a third step, a metallisation (5) is applied in anisotropic manner over the entire surface orthogonally to the semiconductor layer. In the fourth step, the parts of the metallisation between source and gate, and between gate and chain are removed. In the fifth step the metallisation is sintered by heat treatment. ADVANTAGE - Ohmic metal-semiconductor regions are self-adjusting for gate region formation.

Title: Signal processor for audio reproduction, e.g. for CD player - has detector to identify pre-emphasis based on 4 bit code to control de-emphasiser coupled to amplifier gain control
Inventor: ISHIMITSU SHUNSUKE
IPC: H04B1/62
Filed: 1992-06-30
Abstract: The audio processor has a variable gain amplifier (1) that is adjusted dependent upon the input from a CD player. The amplifier acts as a compressor for the output stage. The input signal is received by a de-emphasiser stage (3) in the form of a filter that attenuates the signal above a cut-off frequency. An emphasis detector (5) receives a 4 bit input (Q) that indicates whether pre-emphasis is applied to either 2 or 4 channel signals. When emphasis is present the de-emphasiser generates an output to an input signal level detector (4), to control the amplifier gain. USE/ADVANTAGE - Car radio, tape player, radio etc. Amplifies quiet music sections without affecting louder ones.
Patent DE-4225623-A1 (DE)
Inventor: HEHL KARL
IPC: C04B33/02
Filed: 1992-08-03
Abstract: The invention concerns a method of producing powder-form moulding compounds for the injection-moulding of ceramic materials, the compounds being mixed, before injection-moulding, with a binder which is liberated after injection-moulding. The invention calls for a preliminary stage to be introduced involving a heat treatment or a pressure treatment or both and in which water of crystallization contained in the crystal lattice is driven off. This makes it possible to use ceramic materials in injection-moulding processes. This is of particular advantage in the use of such compounds in porcelain manufacture, i.e. in firing such mouldings to produce porcelain.
Patent DE-4229376-A1 (DE)
Title: Colour embossing method for image signals - transforming foreground colour difference signals into polar coordinate to provide colour transition between foreground and background
Inventor: GEHRMANN RAINER
IPC: H04N9/75
Filed: 1992-09-03
Abstract: The embossing system method is applied to combine a background image signal with a foreground image signal, recorded via an embossing colour, with a transformation process allowing transition colours to be obtained between the colours of the foreground image signal and the background image signal. The colour difference signals (cr,cb) for the foreground image signal are converted into polar coordinate signals (L,W) within the proportional zones where the image signals overlap. Pref. the colour difference signals (crk,cbk) for the embossing colours are subtracted from the colour difference signals for the foreground image signal before their transformation into polar coordinates. ADVANTAGE - Provides colour transition between foreground and background colours.

Patent DE-4237695-A1 (DE)
Title: Non destructive testing of nuclear reactor pressure vessel openings - using an advanced positioning method and equipment to create a regular annulus around the control rod feed tubes for eddy current testing
Inventor: HALLER HANS
IPC: G01N27/90
Filed: 1992-11-07
Abstract: Process and equipment for the non-destructive testing of a circular opening within a nuclear reactor pressure vessel top. The opening is in the form of a feed pipe (3) welded into the pressure vessel top (2). In normal operation a tube (5) is inserted from above the reactor through the feed pipe (3), leaving a regular annular space between the two in the reactor core. Non-destructive testing within the annular space is then achieved using an eddy current probe. However if the feed tube does not project axially through the reactor top (2) the space is not annular and the testing cannot take place. The claimed development uses a pressure device to displace the tube (3) sufficiently so that the eddy current probe (40) can be extended through a hollow (41) in a pressure piece (37) to the hollow annulus (7). The pressure vessel has a groove in which is fixed a manipulator which supports a frame with a bush and housing for a rotating plate (14). Attached to the rotating plate is a vertically adjustable lifting cylinder. At its free end is a piston rod (21) which abuts a special drive (22). The other end of the piston rod is fixed to a support ring which overlaps the tube (5). The free piston end is attached to the pressure piece (37) by means of a bolt (36). Opposite to the pressure piece (37) is a further opposing positioner (39). USE/ADVANTAGE - The feed pipes (3) are used for the insertion of the control rods into the reactor core. Non destructive testing of the annular space region is necessary to check for damage (cracks) within the constituent metal. The process and equipment permit testing to take place when the pressure vessel top has been slightly deformed, during its cooling down, causing eccentric positioning of the tubes (5) within their feed pipes (3).
