Title: Process for the production of wine with residual sweetness suitable for diabetics
Inventor: KIESGEN HANS RUDOLF DIPL ING
IPC: C12G1/02
Filed: 1993-03-19
Abstract: Wine is produced having all tastes from dry to extremely sweet. The legislator has restricted the indication "suitable for diabetics after consultation with a doctor" to 0 to 4 g/l of residual sugar. By currently conventional processes, the glucose content increases above 4 g/l of residual sugar, above the range harmless for diabetics. By influencing the fermentation it is possible to control the conversion of the various sugars in wine to alcohol in such a way that only a small amount of glucose remains when the process is ended early. The means of influencing this are as follows:     1. Inoculation with defined yeasts   2. Temperature   3. Microbial reduction   4. Microbial removal   Production of wine suitable for diabetics.

Title: High-discrimination binoculars (field glasses)
Inventor: DIAMANTIDIS GEORG
IPC: G02B5/20
Filed: 1993-08-07
Abstract: The invention relates to binoculars with high discrimination capability by using light of relatively small wavelength ranges. Both in military and in civil use, for example hunting, it can be important, when viewing the surroundings through binoculars, to detect camouflaged objects and object structures at a greater distance with more ease. As a result of the transmission of the binoculars, which exhibit two transmission bands (Figure 1), a short-wave transmission band with a transmission maximum at 445 nm and an additional long-wave transmission band with a transmission maximum at 750 nm, interferences of the light waves at the object can be noticed, at a great distance, which lead to the detection of contours and separation lines of the camouflaged object. <IMAGE>

Title: Apparatus for the level-contour grinding-off of elevations or grinding-out of defects in the form of edge-free grinding geometries
Inventor: HENTSCHEL FRANK DR ING
IPC: B24B21/16
Filed: 1993-10-05
Abstract: The belt grinding machine is an apparatus for the level-contour grinding-off of elevations and for the edge-free grinding-out of surface defects, which is preferably intended for use with industrial robots. On grinding out surface defects with the aid of the manipulator-guided belt grinding machine, it is possible to achieve a high surface quality of the machining location and edge-free transitions to the unmachined material surface (no secondary burrs) by means of a simple movement control. Prerequisites are the fashioning and arrangement of the drive, contact and tension rollers, and also the flexible grinding tool rotating on these rollers, which is capable of adapting, in the region of the free belt portion, to the workpiece surface to be machined. By virtue of the constructional features of the grinding-belt guiding system, the belt grinding machine is able to absorb forces transversely to the direction of rotation of the grinding belt without endangering the running stability of the grinding belt.

Title: Lighter
Inventor: BLOCK HUBERT K
IPC: F23Q2/16
Filed: 1993-12-08
Abstract: Prior art / criticism: A known disposable lighter according to the generic type is not sufficiently conceived - depending on the situation, for offering a light. After removal from a bag or pocket, a disposable lighter also often has to be brought into the functional position by turning it longitudinally and/or transversely. This can sometimes already be slightly inconvenient, e.g. when intoxicated and/or in disco lighting. Advertising surfaces on the disposable lighter often receive only limited notice by the owner. Object of the invention: Provision of a disposable lighter which is designed more appropriately and/or can be handled more practically - without turning it transversely - and/or is designed to be more effective in terms of advertising. Achievement: a) The disposable lighter is designed to be longer or to be made longer. It has two lighter heads - one at each end. It can be produced from two commercially available small ladies' lighters, e.g. with a transparent advertising cover surrounding the tanks. b) The extended disposable lighter has on the narrow side a web strip which is easily guided, is connected to the gas button, has in the region of the tank body a T-shaped cross-section of a cylinder of a lock, passes over the metal head of the lighter, as a flat body, forms a film hinge at the top in a bent portion and ends as a part fitted onto the gas button.
