Patent DE-3900833-A1 (DE)
Title: Apparatus for the rapid cooling of metal-containing melts, in particular metal-oxide melts
Inventor: KUHN PETER PROF DR
IPC: B22D11/06
Filed: 1989-01-13
Abstract: An apparatus for the rapid cooling of metal-containing melts, in particular metal-oxide melts, to form a solid product strip has two rotating solids of revolution, if necessary subjected to forced cooling, which at the start of the cooling process are in contact along a common generatrix and by moving away from one another form a gap for the passage of the melt which has accumulated in front of the gap in the direction of rotation. To avoid seals for the gap, provision is made for the common generatrix of the solids of revolution to have a curved arcuate shape and the axes of rotation of the solids of revolution to be arranged spatially relative to one another in such a way that the end points of said generatrix are their geodetically highest points, and for the level of the melt to be adjustable on the line joining the end points or below the same. In this way, a depression for receiving the melt is formed, which is closed up to the geodetically highest points and delimited solely by the surfaces of the solids of revolution.

Title: Hydraulic spiral motor
Inventor: SPEER ANTON DIPL ING
IPC: F01B13/00
Filed: 1989-01-18
Abstract: A hydraulic spiral motor HSM has a special device by means of which a brief external energy is required only at the start (actuation or at the end to bring to a stop) in order to convert the said motor into an open permanent force system. (According to a spiral function r = f( phi ).) The open force system with permanent resulting torque acting about the centre of rotation of the rotation disc of the spiral motor brings about permanent rotation. A spiral motor has a long service life, does not require any explosive or combustible fuels thus not giving rise to any pollution of the environment, is very environmentally friendly and quieter than electric motors when it is operating. The overall volume of said motor corresponds approximately to that of a conventional motor of the same kW power. It is suitable for motor vehicles of all kinds, and for industrial applications, the aircraft industry, for vehicles and in electric power stations for driving electric generators to produce power. Therefore, this ballast with explosive and combustible fuels in the tanks which conventional motors require is eliminated. Such spiral motors are independent of any fuel consumption and have a very long service life.

Title: Controlling movement of ring rail in spinning machine or twister - uses drive which is switched over to reverse rail movement direction
Inventor: REYER HERBERT DIPL ING
IPC: D01H7/64
Filed: 1989-04-17
Abstract: A process is to control the movement of a ring rail of a spinning machine or a twister and uses a drive which can be switched over to reverse the movement direction of the ring rail. The rail movement is registered by means of an incremental emitter which emits pulses. The pulses emitted during the downward movement of the rail are counted. When a preselectable pulse number is reached, the drive is switched over to the upward movement.  The preselected pulse number to be counted during the upward movement is bigger than the pulse number to be counted during the downward movement. ADVANTAGE - The adjustment of the up and down movement of the ring rail is simple and the need for time consuming assembly and adjusting operations is eliminated.

Title: Automatic sound level adjuster for car audio system - has ARI receiver and variable amplifying circuit deriving compensating valve from noise and audio signals
Inventor: KATO SHINJIRO
IPC: H03G3/00
Filed: 1989-07-13
Abstract: The system has a receiver for traffic information transmissions.  A variable amplifier circuit (6) receives the audio signal, while a sound level compensation magnitude is derived by a control circuit (7) according to the level of a noise signal (24) and the audio signal level. The amplification is controlled by the sound level compensation magnitude for the sound level adjustment. A memory stores a value after receiving the traffic information transmission by subtracting the sound level compensation magnitude during the reception from the sound level directly prior to the reception. The amplifying factor of the circuit is controlled at the time point of the traffic information transmission reception such that the sound level equals a summation value of the stored value and the sound level compensation magnitude. ADVANTAGE - Continuous sound level control for traffic information transmissions.

Title: Ceramic heating plug using embedded ceramic resistor - has improved resistance to thermal cycling as result of material selection and dimensions
Inventor: KIMURA YUKIHIRO
IPC: F23Q7/00
Filed: 1989-07-26
Abstract: A green sheet is prepd. consisting of an organic binder and electrically conducting ceramic, pref. nitrides or carbides of the elements Ti, Zr, Hf, V, Nb, Ta, Cr, Mo or W. A suitable resistor shape is stamped out, pref. as a U-shape. The resistor is embedded in ceramic powder based on  Si-nitride. The product is then compressed with a suitable pressure in a direction parallel to the width of the resistor and sintered. Also calimed is a product made by compression during sintering which reduces the distance between the parallel tracks (22-25) of the resistor. The product claimed pref. has a cylindrical shape or is a sheet. The main resistor cross section area is pref. 1/10,000-1/38 of that of the ceramic end-product. In addn. the total area of the resistor cross ection is less than 1/6 of that of the ceramic end product. Also claimed is a min. distance between the centre of the resistor tracks and the outside surface of the element which is more than 0.15 times the element dia.  or thickness, but less than 0.5 times this dimension. USE/ADVANTAGE - The element uses better matched parts than currently available elements making it more resistant to thermal cycling. The dimensions are chosen to produce  acceptable stresses. As a result the heating element survives 20,000 cycles, without suffering cracks, of switching on and off at 1200 deg C followed by fast cooling with an airstream. The rapid heating elements are used in diesel engines and other applications requiring a fast temp. rise.

Title: Fluidising indirectly heated drying bed - by evolved vapour before processing vapour to fitness for emission
Inventor: WOLF BODO DR ING
IPC: F26B17/10
Filed: 1989-12-30
Abstract: The fluidising medium for a bed of lignite, peat, filter cake, slurry etc. indirectly heated while drying derives from the vapour, esp. of water, emitted during drying. The solids when dried are extracted for tipping or any other desired processing, while the emitter vapour is collected for purificn., cooling and possibly re-use after the heat content has been recovered. Ratio between added wet material and extracted dry material is controlled to provide a bed temp. only vapourising materials below specific b.pt. Non-condensible fractions and materials insoluble in condensate are sepd. by cooling and condensing emitted vapour before entry into atmos. possibly after de-odourising. Supplied solids, depending on grain size, may be mixed with condensate to form a pumpable slurry sprayed onto the bed surface. Wed sludges are converted to fluidisable consistency by mixing with previously dried material. ADVANTAGE - A large fraction of drying energy is recovered, e.g.  78% in a lignite dryer.
