Title: Process for moulding raw sausages, long-keeping sausages and comparable products
Inventor: KORTSCHACK FRITZ
IPC: A23L13/60
Filed: 1989-04-10
Abstract: The process enables the starting material to be chopped to the particular desired grain size in the cold (frozen) state in the cutter or other apparatuses. The cuttered sausagemeat (emulsion) ready for filling is charged loosely into a mould. With the aid of a stamp, the composition is compressed and held in the mould under pressure by means of an apparatus (sprung cover). The previously unavoidable fluid motion of the raw sausage emulsion during the filling operation is avoided, therefore no fat films can form. The short production time and the possibility of processing completely frozen raw material considerably improve the hygiene status. In addition to production reliability, the expense of the previous filling operation (filling machine and labour) is reduced several times and the use of casings is dispensed with.

Patent DE-3919302-A1 (DE)
Inventor: EBISU KOJI
IPC: H04N1/32
Filed: 1989-06-13
Abstract: A system for transmitting image data by amplitude modulation in which alternate pixel data a, b, c..... are modulated in a modulator 14 so as to correspond to positive and negative half periods of a carrier signal Sc. The modulated data are then demodulated by a demodulating circuit 20. As a result of this technique, the transmission rate and the recording density of the image data can be doubled as compared with a system in which data is modulated over full periods of the carrier signal. The system may be used in the recording of still images on a portable audio cassette recorder with the provision of suitable frame memories for colour or black and white image signals. Using the technique a single still frame takes about 2.8 seconds to reproduce. Sound and vision signals may be recorded one in each of two stereo tracks available. <IMAGE>

Title: Detecting artificially generated random number series - analysing arithmetic features in sequential samples to classify any given random series as natural or artificial
IPC: G06F7/58

Title: X-ray laser for shorter wavelengths - consists of photon accelerator to reduce the wavelength of photons generated by the pumping laser
Inventor: BLUM JUERGEN
IPC: H01S4/00
Filed: 1989-07-31
Abstract: The feature, is that high energy type 4 photon oscillations are generated with low or high frequency and in high energy magnetic fields, the photon accelerator is based on the principle of the laser-transformer, the anti-stokes-Raman laser and the water-jet pump. The core of the accelerator consists of a laser-crystal rod constructed as follows, Cr-isotope, Nd:GSGG and Cr, Nd:GSGG laser crystals of a concn. depending on the energy and frequency of the photons, Nd:YAG, Cr, Nd:GSGG laser crystals, polycrystalline Ag-halogenides or chalocogenide glasses. The first coating mantle consists of a mixt. of quartz glass and the laser crystal Nd:YAG and has an optical transparency of 67%, a mixt. of quartz glass and the laser crystal Cr, Nd:GSGG with the same transparency or polycrystalline material with a transparency of 67%. The second coating mantle consists of the Nd:YAG crystal tube, the Cr, Nd:GSGG laser crystal tube or a polycrystalline tube. The outer laser crystal is cut into 7 equal pieces of which the optical transparency is modified by additives in the region of photons of 1-21 eV as follows,: zones 1.7:87% zones, 2,6:77%, zones 3/5:72% and zone 4, 69%. The ends of the zones are polished and the parts fused together using zone melting. On the upper and lower side of the outer mantle the 2 connecting fibres from the laser-pulse transformer are attached. The light conducting sec. of the transformer acts as pumping source. The photons generated by the Nd:YAG laser in the core are accelerated by the photon current of the system to the energy level required. USE/ADVANTAGE - The system allows harder X-ray-lasers to be mfd. i.e. acceleration into X-ray and gamma-ray region is possible. The Xray laser is used in the phot-lithography processes of high density, small feature size integrated circuits, e.g. 4M Drams.

Patent DE-3931092-A1 (DE)
Inventor: KISS AKOS DR
IPC: C09C1/00
Filed: 1989-09-18
Abstract: The greyish black occlusion pigments according to the invention, which are based on zirconium silicate as occluding substance and carbon black particles as occluded phase, are prepared by calcining a mixture of zirconium dioxide, a source of silicon dioxide, the carbon blacks and mineralisers under reducing conditions at 900 - 1400  DEG C. The process is characterised by the use of zeolites having an SiO2/Al2O3 molar ratio of greater than 4, preferably greater than 10, as SiO2 source. By including a coupling agent, in particular a silicone oil, it is possible to increase the depth of shade. The use of zeolites makes it possible to use different zirconium dioxide grades and the preparation of pigments having a higher carbon black occlusion rate.
