Title: Method for growing a single crystal
Inventor: SCHMITTBERGER HORST
IPC: C30B7/00
Filed: 1988-03-02
Abstract: A method is described for growing a single crystal by evaporation of a solvent from a corresponding droplet which is held without contact in a stationary sound field (sonic field). In order to set a specific concentration of the solution in the droplet, a stock of solution having a predefined concentration is placed in the process chamber at a distance from the droplet, so that, via diffusion processes between the droplet and the stock of the solution, the desired concentration of the solution in the droplet is set.

Abstract: The invention relates to a straight connection piece (1) for in each case engaging partially, preferably about halfway, in hollow profiles which are to be interconnected at their end faces and preferably serve as spacing elements for insulating glass panes or the like. In this case, the outer cross-sectional shape of the straight connection piece (1) like the hollow profile, whose inner hollow cross-section is adapted thereto, has at the transition point of the wall of the hollow profile which is remote from the gap in the insulating glass pane or the like in the use position and the profile webs facing the pane faces an approximately oblique or rounded transitional surface (3). The straight connection piece (1) according to the invention is characterised in that there is provided on either side of the centre of the straight connection piece (1), which corresponds to the butting point of the profiles, a ramp (4) which rises towards the centre of the straight connection piece (1). In this arrangement, a clearance is provided between the straight connection piece (1) and the inner side of the hollow profile at the beginning of said ramp (4) which is remote from the centre, and at the end of which the straight connection piece (1) has a sliding or clamping fit in relation to the hollow profile or the ramp (4). The object of the straight connection piece (1) according to the invention is to align mutually distorted hollow profile ends of, in particular, a thin- walled hollow profile in their longitudinal mid-planes (E1, E2). <IMAGE>

Patent DE-3819027-A1 (DE)
Inventor: MEYER WERNER
IPC: B29C43/56
Filed: 1988-06-03
Abstract: In methods of this type, the parts to be fixed or the roll material to be laminated are/is transported between two air-impermeable conveyor belts through a heating-pressing zone and thereafter through a cooling zone. 
<??>As practice shows, inclusions of air and vapour in the parts to be glued to each other under the effect of heat and pressure often impair the uniform adhesion of the parts glued to each other over their surface. 
<??>To remedy this, it is proposed to generate a partial vacuum in the intermediate space (Z) between the two conveyor belts (1.1/1.2, 2.1/2.2). For this purpose, use is made of channel-shaped suction nozzles (8), having flexible sealing strips (8.21, 8.22) and connected to a suction turbine (10), between which nozzles the conveyor belts, arranged one above the other, preferably slide on both sides.

Title: Double cover system for lock vessels
Inventor: FABIAN HANS JOHANN DR
IPC: B01J3/02
Filed: 1988-06-06
Abstract: A double cover system gas-tightly closing at superatmospheric pressure and under vacuum is specified for a lock vessel. The lock vessel (1) can be connected to boxes (4) (Fig. 1), which can be operated at superatmospheric pressure or under vacuum. For connection to these boxes, the lock vessel has, as a double cover system, a vessel cover which can be connected gas-tightly to the vessel flange (11) of the lock vessel and has a lock cover (8) which can be connected to the vessel cover in such a manner that the lock vessel flanged to the box, after equilibration of the pressure to the pressure prevailing in the box can be opened to the work space of the box by lifting off the lock cover. In order that the double cover system can be easily opened and closed from the work space of the box, a pin lock (9) is mounted on the vessel cover (3), the bolt (10) of which pin lock, when the lock vessel is closed, engages in a closing plane (12) on the vessel flange (11) in such a manner that the vessel cover is displaced in an axial direction and is pressed onto a sealing ring (14). The sealing ring is laid in a flange plane of the vessel cover, the normal of which plane runs parallel to the vessel axis (2). For attachment to the lock cover, the vessel cover has a further pin lock (30) which, after flanging the lock vessel to the box and gas-tight connection via a further sealing ring (23) which is inserted between vessel flange and box, and after opening ...

Title: Air-cooled internal combustion engine
Inventor: BOJE HERBERT H
IPC: F01P11/08
Filed: 1988-06-14
Abstract: In the arrangement of the engine oil cooler on the pressure side of the air-cooling fan, the cooling air needed for the engine oil cooler must be brought to the pressure level of the engine cooling air. This has an unnecessary cost in terms of power and noise. By arranging the engine oil cooler outside the pressurised air flow of the cooling fan and acting on this with a low pressure fan, the rate of air flow and hence the power and noise level of the air cooling fan is reduced. The invention relates to air-cooled internal combustion engines. <IMAGE>

Title: Water recovery from natural air humidity for cultivating plants, breeding animals and for human needs
Inventor: WEBER ADOLF PROF DR RER NAT
IPC: F25B21/02
Filed: 1988-09-09
Abstract: In areas of high air humidity and high insolation with a simultaneous lack of a natural occurrence of water, the intention is to recover water, by means of suitable devices, from the air with small or large, mainly self-sufficient systems. These are distinguished in that the required temperature differences are achieved in most cases by direct or indirect utilisation of the insolation and/or of the radiation towards the night sky. The outlay for assisting the natural air movement and for other drives and controls such as may be required is comparatively low. Provision of additional cover by photovoltaics is possible in all cases.

Patent DE-4002209-A1 (DE)
Inventor: KLENK MARTIN DIPL ING
IPC: G01M15/11
Filed: 1990-01-26
Abstract: A process for identifying a misfiring cylinder in an internal combustion engine with Z cylinders comprises the following steps. For each cylinder z (z of 1 - Z), a time-interval T(z) in which the crankshaft rotates through a given crank angle in the combustion cycle of the cylinder is measured, and for each cylinder the time difference DT(z) = T(z) - T(z-1) is calculated. The existence of misfiring is detected by any cylinder-nonspecific process. The first time that misfiring occurs during the process, the mean differential value for each cylinder is calculated and compared with a threshold value. When a predetermined mean value-threshold value criterion is met for one cylinder, this cylinder is considered to be misfiring. A misfiring cylinder can be reliably identified by this process without using special sensors.
