Title: Photographing moving objects with video camera - provides scanning mirror in beam path between object and camera with deflection such that movement of object image is compensated
Inventor: TROPF HERMANN DR ING
IPC: G01N21/89
Filed: 1992-03-05
Abstract: The method is carried out using a video camera (2). The deflection results cyclically with a frequency corresponding to the full field or the half field frequency or alternatively to a whole number multiplication or a whole number fraction of this. An oscillating or rotating or other cyclically moving mirror (3) is used as the deflector. An oscillating or rotating or other cyclically moving transparent panel with parallel faces is used as the deflector.

Title: Fibre strand winder used to wind rounds - has pins at edges of winding mandrel to prevent slippage on a direction change
Inventor: ZANKL WOLFGANG
IPC: B29C53/80
Filed: 1992-04-10
Abstract: The appts. to wind fibre strand material round a winding mandrel (10) has pins (16) at the ends of the mandrel (10) where the material carrier (20) changes its winding direction, to prevent material slippage. The pins (16) are pref. at intervals of 2.5-3.0 mm. The winding mandrel (10) is cylindrical, rotating round the cylinder axis (33). The material carrier (20) moves parallel to the cylinder axis (33). the pins (16) are around the edges of the mandrel (16), round its circumference. A ring unit, pref. of Teflon (RTM), can be at the edges of the mandrel (10), to hold inserted pins (16) without prior drillings. USE/ADVANTAGE - The appts. is used to wind rovings or fibre strand material to form a spirally-wound fibre bonded component. The width and thickness of the wound layers can be varied, and the same appts. is used for a variety of windings. The roving is protected from shearing, with optimum material consumption. Light tracking errors in the winding are neutralised through the direction change.
Patent DE-4212307-A1 (DE)
Inventor: GROS GERHARD DR
IPC: C21D1/76
Filed: 1992-04-13
Abstract: Nitrogen produced by non-cryogenic methods, such as those using pressure-change adsorption or membrane installations, cannot owing to its high oxygen content of about 0.1 to 5 % V/V, be used for the heat treatment of metals, or can only be used to a limited degree. The invention proposes an endothermic catalytic conversion of the oxygen contained in the nitrogen by means of hydrocarbons to give a protective gas which is suitable for the heat treatment of metals.

Patent DE-4221312-A1 (DE)
Title: Automatic aspiration and injection set - gives automatic insertion free of pain with accurate location of vein alignment and depth
Inventor: HAG RENE
IPC: A61M5/42
Filed: 1992-06-29
Abstract: The automatic aspiration and injection set uses physical effects to locate the direction of a vein. It can use ultrasonics, with at least two dopplers, with a clock indicator to show the alignment of the vein as the instrument is moved across the skin. A further indicator shows the depth of the vein. When the orientation and depth of the vein have been registered, the injection point is disinfected automatically, and the injection point is treated with procaine to suppress pain. The system can be adapted for vein aspiration and blood removal. A control gives exact positioning and stability, and a further control prevents the injection of an air bubble. With an intramuscular injection, the insertion is shot into the tissue for pain relief. The system can have a blood pressure cuff/meter to allow vein aspiration or removal to correct the blood pressure ratio. When used for infusion/transfusion, a drop counter or injection time monitor allows optimum settings, and give the timing for blood to be taken as a laboratory sample. For an intracutaneous or subcutaneous injection, a disc is fitted to the cone of the cannula which can slide, be fixed and be angled. The instrument can be charged from an ampoule, free of pyrogen. USE/ADVANTAGE - The instrument is for intravenous and intramuscular injections and the like. The instrument gives a pain-free action, with accurate location of the point of insertion and insertion depth.

Patent DE-4228770-A1 (DE)
Inventor: WEYH WERNER DIPL ING
IPC: B67D1/07
Filed: 1992-08-28
Abstract: Carbonator apparatus used in connection with a postmix beverage dispenser system includes a water delivery branching circuit for the water fed under pressure from a fresh water source and which is used to fill a storage tank for carbonated water produced therein and to supply fresh water to a recirculating type of fresh water cooling structure which includes a water circulating coil located in the bottom of the storage tank and/or a water channel guide located on the outside of the storage tank. The branching system selectively enables fresh water to be fed into a carbonator storage tank where the water is blended with CO2 gas or is guided around it while being cooled without being carbonated so that either cooled carbonated water or non-carbonated water is delivered to a mixing station along with a drink concentrate.

Abstract: Additives (I) for paper prodn. comprise cationic polymers with reduced viscosity 0.1-10 dl/g (at 0.1 g/dl in 1N-salt soln. at 25 deg. C), contg. 20-90 mole% units of formula (1) and/or (2), 0-2 mole% units of formula (3), 0-70 mole% units of formula (4) and 0-70 mole% units of formula (5); or (I) can contain 50-90 mole% units (1) and/or (2), pref. with 2-20 mole% units (3), 0-48 mol% units (4) and 0-49 mole% units (5). In the formulae, R1, R2 = H or Me; R3 = H or 1-4C alkyl; X = anion. USE/ADVANTAGE - Used as an additive in paper prodn. for improving the degree of beating, the filler retention and the strength of the paper (claimed). (I) have excellent properties as paper prodn. additives (see above); they are very stable (even in dil. aq. soln.) and are pref. used under neutral or weakly alkaline conditions, i.e. with cheap CaCO3 as filler. Prior-art cationic polymers are not sufficiently dissociated under these conditions, and also require large amts. of Al sulphate when used for binding anionic strength improvers, which causes machine wear, loss of paper quality and contamination of effluent.
