Patent DE-19750983-A1 (DE)
Title: Separation of mixtures based on specific gravity difference in fluid medium
IPC: B03B9/06
Filed: 1997-11-18
Abstract: Comminuted plastic mixtures are introduced separately from a separation liquid into a stirred vessel (17) with a conical base. Concentration in the liquid is ca. 10-20 wt.%. Variable-pitch, bladed stirring to uniform distribution with laminar flow ensues, such that sinks, including heavy metals, accumulate in the cone. The mixture leaves by a side exit at a central level. Sinks leave via the base, extracted periodically. The mixture enters the separation vessel (1) above its conical base, through a specially shaped distributor with conical sections. The mixture is introduced turbulence-free into the separation fluid, past flow-calming vanes. Particles of about 25 mm size rise or sink, producing floats and one or more dense fractions. A flexible siphon tube (12), one section of it elevated by block and tackle (13) to the fluid level in the tank, is connected through a basal valve, to control the fluid phase and fraction extracted. The light fraction leaves at the top via a drain pipe and overflow weir system. Heavy fractions leave via the conical base. Fractions leaving are screened (23, 26) and filtered (24, 27) from the liquid phase which enters a buffer tank (25) for recycling (28). Products are dried and stored. An Independent claim is included for the apparatus for the above process. Preferred Features: The medium is water, or an aqueous solution of various inorganic salts, controlling its density. It is alternatively a lighter, organic fluid. Other valuable heavy fractions are recovered, especially metals.

Patent DE-19805367-A1 (DE)
Inventor: RUNKEL DIETMAR
IPC: C08B31/04
Filed: 1998-02-11
Abstract: The invention relates to a method for producing compostable starch esters which can be subsequently converted into thermoplastically deformable products, said method being carried out in a continuous or discontinuous way. The activation of starch with carboxylic acid anhydrides is carried out under intensive influence of mechanical energy, pressure or cavitation whereby the organophoby of starch particles is overcome. Consequently, the carboxylic acid anhydride penetrates quickly and quasi-thoroughly in the starch particles, without any change in the partially crystalline structure of said particles, at the time when the acid carboxylic anhydrides simultaneously react with residual moisture of the natural or modified starches, without any noticeable destructuring. According to the invention, activation is carried out at a temperature ranging from 10 to 140  DEG C and at a pressure comprised between 0.001 and 100 bars, preferably at a temperature ranging from 15 to 100  DEG C and at a pressure comprised between 0,01 and 1000 bars.

Title: Foldable bed with wooden sides, head- and foot part for more attractive appearance
Inventor: LANGEGGER JOSEF
IPC: A47C19/12
Filed: 1998-03-18
Abstract: The bed (1) has a frame comprising two side walls (6,7,11,12), a head- (3) and a foot part (4) and a center part (5,24) to which the sides (6,7) are pivotally joined. The gap (20) between sides (11,12) and center (24) is almost invisible when the bed (1) is opened. Two wooden sheets (26,27), joined to an adjusting mechanism (32-38) are simultaneously pulled to the sides or pushed to the center for either folding or unfolding and are used to bridge the gap between the slats (19) positioned on both halves of the bed (1). The specific design creates a more ''permanent'' look of the bed (1) because all the details of the folding mechanism are hidden behind a wooden cover.

Abstract: A CVD reactor has a fluid inlet unit which is temperature controlled by a positive temperature gradient created by a purge gas at its upper side and by the CVD media at its underside. A CVD reactor has: (a) a fluid (CVD media, etc.) inlet unit comprising a hollow body which is spaced from the reactor lid and which has an apertured underside heated by thermal radiation and/or conduction from the susceptor (wafer holder); and  (b) a purge gas inlet positioned between the upper side of the hollow body and the reactor lid for introducing a purge gas to achieve temperature control by heat conduction into the gas.  The hollow body heating and cooling conditions are adjusted such that the underside is temperature controlled by the CVD media without external temperature control medium supply and such that a positive temperature gradient is created between the upper side and underside of the hollow body.

Patent DE-19831763-A1 (DE)
Title: Throttle control for IC engine
Inventor: SATO KUNIHIKO
IPC: F02D41/08
Filed: 1998-07-15
Abstract: The IC engine has an electronic control for the throttle valve setting which includes an idling speed control. The control system computes a target speed for the engine. If this coincides with the idling speed then the control ensures that the appropriate correction is applied to reach the target speed. If the target speed is different to the idling speed then the correction is inhibited and the target speed can be attained. The control system selects a target speed different to the normal idling speed if, for instance, the engine coolant temperature is less than a set level ie. cold starting. The computed target speed takes into account any application of the throttle control.

Title: Industrial electrostatic air filter in which the air stream is split up into parallel paths so that a high throughput is possible
Inventor: GUTMANN RUDOLF
IPC: B03C3/02
Filed: 1998-08-20
Abstract: Air is drawn through the filter casing from inlet (2) to outlet (3) by fan (18). An easily demountable metal grid (4) removes the coarse particles before the air passes into a number of parallel tubes (11) that contain conventional electrostatic filters. The air then exits into a common chamber to equalize the pressure before the fan passes it into a similar chamber above the apex of a conical filter (19). This filter is made of activated charcoal, principally to remove any ozone produced by the electrostatic discharge. A portion of the outer casing near the fan is provided with sound absorbent material (37). A modification, where each tube (11) has its own, smaller, fan is considered as a means to reduce noise. A further design using a rectangular outer casing is described.
