Title: Nozzle head arrangement for mouth douche - involves U=shaped head inside which are multiple spray nozzles
Inventor: EENBOOM ALGUND DR MED
IPC: A61C17/02
Filed: 1990-09-15
Abstract: The U-shaped nozzle head (1) is provided with spray nozzles from which spray jets (8a, 8b) are ejected, in the area of two arms. The nozzles are located at a specific min. distance from the surface of the teeth which guarantees that the spray jets are formed separately from one another, thus maximising the cleansing effect. This min. distance is achieved by distance pieces in the form of end areas (7) of the central zone of the nozzle head. The U-shaped nozzle head is therefore located around the teeth bell or collar-fashion. This means that the end surfaces of the end areas (7) are guided on to the surfaces of the teeth (6). USE - For teeth and mouth cleansing.

Title: Tempering firm organic material esp. thermal disinfection of bone transplant - using two independent heat sources and incubator filled with sterile water under control comparing temp. difference with stipulated value
IPC: A61L2/12
Filed: 1990-11-28
Abstract: The first heat source warms the organic material directly, preferably in the centre region. The second source indirectly heats the material (4) by the water in the incubator (2). The temperatures (T1,T2) pertaining in the organic material and the heat-conducting medium (3,7) are measured. In a control (6) the difference of these measurement values (delta T1) is compared with a stipulated value (delta T5). The first heat source is only activated until the latter value is attained. Then this source is deactivated until the difference of the measured values (T1,T2) equalises, i.e. disappears. The second heat source is then either continuously activated or only while the first source is deactivated. This cycle is repeated until the organic material has reached a predetermined temperature without a temperature gradient remaining in it. ADVANTAGE - Reduced disinfecting time without exceeding local handling temperature which could lead to reduction of functional efficiency of the organic material. Partical or completely automatic control possible.

Title: Hologram printing on paper or cardboard at high speeds - has varnish layer on web print material to be hardened by UV setting
Inventor: MATTHIESEN JOHANNES
IPC: G03H1/02
Filed: 1991-09-30
Abstract: To apply holograms etc. to printing paper and cardboard, at least the varnish layer to hold the microstructure can be set by radiation, esp. by UV. Varnish is set from the matrix side and through the matrix, which is transparent to radiation, through the plate cylinder or matrix carrier. Pref. varnish layer is hardened before the print material in contact with the matrix is removed. On rotary printing, the varnish layer is hardened by radiation while it rotates round the plate cylinder, and through the cylinder wall from an inner radiation source, providing ultraviolet or electron beam heat. Shaping matrix is a single matrix, continuous belt loop, a cylinder or cylinder sleeve. Shaping medium has 0.2-2.0 wt.% of a separator to release the hardened forming medium and prevent clamping of the holographic positive/negative fine structure, with a chemical which has greater adhesion to the print material than to the matrix. Print material is a clear or opaque plastics film or paperweb, or polyester paper, a fabric and pref. a dimensionally stable fine woven plastics. Material can also be a smooth film which acts as a carrier during the shaping and hardening stages to give a self supporting film to hold the microstructure and be rolled. Heat activated separator is applied to the polyester carrier followed by a radiation setting varnish layer. Separator contains wax or Si. After the hologram structure has been shaped, a reflective metallising is applied over the varnish to be covered by a transparent protective layer which is set by pref. UV radiation. Reflective metal layer can be applied before the hologram structure is formed and inserted into a second varnish layer. ADVANTAGE - Cheap and direct application of holograms and other fine structures to paper or cardboard or opaque film, at high printing speeds.
