Title: Plastics working tool - having thin ceramic coating on its plastics-contacting surface
Inventor: KELEMEN LAJOS DIPL ING
IPC: B29C48/35
Filed: 1990-05-31
Abstract: In a plastics working tool, esp. for extruding or rolling thermoplastics, in which at least the major part of the plastics-contacting surface of the tool is a ceramic surface, the novelty is that the ceramic surface is formed by a 0.3-0.5 mm thick ceramic layer deposited on the rotational face of a metallic tool body. Prodn. of the tool involves (a) preparing a metallic tool body having dimensions, at any place where a ceramic face is to be formed, which differ from the nominal tool dimension by the intended thickness of the ceramic layer; (b) subjecting the tool body to degreasing, conditioning by powder blasting, and preheating; (c) depositing a base layer and an at least 0.7 mm thick ceramic layer by flame or plasma spraying; and (d) grinding the ceramic layer to the final thickness of 0.3-0.5 mm. USE/ADVANTAGE - The tool is useful as an extruder nozzle or foil roller e.g. for processing molten polyolefins such as linear polyethylene. It is resistant to baked-on eg-deposits so that cleaning operations can be eliminated, has a thin ceramic layer so that thermal conductivity of the tool is not significantly affected, and is not significantly more expensive than conventional tools since the expense of usual operations such as polishing and Cr plating is avoided.
Patent DE-4017806-A1 (DE)
IPC: F26B23/02
Filed: 1990-06-01
Abstract: The process according to the invention, in which the heat from flue gases generated in a combustion chamber is utilised in a drier charged with the material to be dried, is characterised in that the flue gas-free vapours leaving the drier are recirculated to the drier and, upstream of the drier, heated indirectly by the flue gases leaving the combustion chamber to the temperature required for drying the material to be dried, a vapour part-stream being branched off from this circulation and taken to the combustion chamber. 
<??>The apparatus for carrying out the process provides that, from the cyclone or cyclones (12) used in such processes for precipitating the dry material, a pipe (13) for the vapours leads back to the drier (8), that a heat exchanger (7) for the indirect heating of the vapours by the flue gases leaving the combustion chamber (1) is arranged in the pipe (13), and that a line (6), branching off from the pipe (13) upstream of the heat exchanger (7) in the direction of flow and leading to the combustion chamber (1), is provided. This invention makes it possible, at low cost, to maintain lower pollutant emission limits than those hitherto prescribed, to improve the efficiency and at the same time to reduce the explosion risk.

Title: Treatment of surfaces e.g. metal surfaces - using vortex-bed reactor in which filling is mixt. of inorganic and organic granulated substance and is environmentally friendly
Inventor: KRUEGER MANFRED PROF DIPL ING
IPC: B01J8/32
Filed: 1991-01-24
Abstract: In treatment of surfaces, partic. cleaning reaction space is of a vortex-bed reactor in which the filling is a mixt. of at least one inorganic and at least one organic granulated substance. Granulated beechwood, cherry stones, walnut shells, peach stones and rough-ground maize - separately or in combinations with one another - are used as the organic constituent of the mixt.. Glass and/or ceramic materials are used as the inorganic constituent. Al2O3 may be used as an inorganic ceramic constituent. Vol. of inorganic materials is less than that of organic materials which also form the cover layer on top of the vortex layer. Organic acids are used to prevent electrostatic charges forming in the reaction space. Inert or noble gases can be used instead of air in the reactor. USE/ADVANTAGE - Used to clean (decrease, spotlessly dry) various types of metal surfaces, partic. sensitive, highly shiny metal surfaces. Method is environment-friendly and poses no problems connected with the disposal of the used filling material.
Patent DE-4106040-A1 (DE)
Title: Supersonic projectile e.g. bullet speed and impact position measurement - using fixed pressure sensors to measure time and space characteristics of bow wave
Inventor: NIEKE HELMUT DIPL ING
IPC: G01P3/64
Filed: 1991-02-22
Abstract: The method uses fixed sensors (6,7) along the trajectory of a supersonic body (1), pref. a projectile, to measure the bow wave pressure at two points (6,7). The time lapse between the pressure variations at the sensors gives a measure of the body's speed. Similar measurements using additional sensors (12,13) not on the trajectory enable bow waves from other supersonic bodies to be distinguished. The impact point of the projectile on a plane target can be accurately determined by measuring the arrival times of the bow wave at three pressure sensors in a plane close to and fixed geometrically w.r.t. the target. USE/ADVANTAGE - In shooting practice or competition enables every bullet's performance to be characterised. Present optical methods measure only speed and use sacrificial sample whose behaviour may not correspond to that of all batch.
Patent DE-4107496-A1 (DE)
Inventor: SCHULZE ECKEHART
IPC: F16K31/06
Filed: 1991-03-08
Abstract: In a 4/3 way magnetic valve with spring-centered basic position 0, a pulsed current of relatively high frequency, e.g. a frequency fi of 10 kHz, flows through each of the two exciter coils (18 and 19) for setting the alternate excited function positions I and II and for setting defined flow cross-sections in these functions positions. These pulsed direct currents undergo square-amplitude modulation so that current flows through the exciter coils alternately for time-intervals T1 and T2. The frequency of this amplitude modulation, whose period T is equal to the sum of the excitation time-intervals, T1 and T2, of the two exciter coils, is approximately 400 Hz. The magnetic valve (10) has a central position (69) rigidly mounted in the housing and a mobile valve element in the form of a soft iron sleeve (68) which is also the armature of the double-stroke magnetic system (17). The function position and deflection of the armature are chosen in function of the ratio T1/T2 of the time-intervals for which current flows alternately through the exciter coils (18 and 19).
