Title: Electrostatic powder coating system
Inventor: KRAEMER ERICH
IPC: B05B15/12
Filed: 1988-03-01
Abstract: The invention specifies an electrostatic powder coating system which has a chamber in which the material to be coated is coated during the electrostatic powder coating process. The filter device for recovering the powder from the powder-air mixture in the chamber in this case comprises an air receiver, in which a vacuum prevails, and one or more revolving, endless filter belts, the filter device partially or completely extending over the wall surfaces of the chamber. With this filter device the powder is continuously and constantly filtered out of the powder-air mixture and then transported with the aid of the filter belt to one or more powder-collecting containers. With the aid of an electrostatic blow-off device the powder remaining stuck on the outside of the filter belt is blown into the powder-collecting container, the powder beforehand passing through a screening device. The filter device may be subdivided into a plurality of filter subunits which are, for example, assigned to the side-wall surfaces, the bottom surface and/or the ceiling surface and/or the rear wall. The blow-off device is arranged in a vacuum-free zone. A description is also given of an embodiment of such a system in which the chamber walls are formed directly by the filter device and the system has a scaffolding-like basic frame on which the filter device and/or the filter subunits then ...

Title: Device for uniform laying down of the filaments in the manufacture of a bonded fabric using the direct method
Inventor: HEINZE ACHIM
IPC: D04H3/03
Filed: 1988-03-08
Abstract: The device can be used for installations which orientate with compressed air the filaments extruded from an extrusion die arrangement, and in which the formed fabric is laid down on a perforated transport belt. According to the invention, jet screens 5 are arranged at an angle 5@ </= ss </= 15@ to the vertical. They have openings with a diameter 1 mm </= d </= 3 mm, the horizontal spacing of which is 1.5 d </= a </= 3 d and the vertical spacing of which is 2 d </= b </= 6 d. Blowing heads 2 are angled from the vertical towards the jet screens by 15@ </=  lambda  </= 25@. By means of angled blowing heads/jet screens and the perforation of the jet screens, pulsating individual air flows are created at the openings, which bring about the filament spreading which is necessary for a uniform laying down of the filament bonded fabric. The formation of the individual air flows is further favoured by arched sections 9. Outgoing-air shields 10 also bring about, by air accumulation, an additional spreading. <IMAGE>

Title: Thread-milling tip which can be fastened to a holder
Inventor: LINK HANS JOERG
IPC: B23B27/14
Filed: 1988-03-10
Abstract: The known thread-milling tips are designed in such a way that they have to be fastened obliquely in the holder in order to achieve the requisite clearance angle. But in a thread-milling tip fastened to the holder in this way, it can be difficult or even impossible to set the optimum rake angle. The novel thread-milling tip is therefore to be designed in such a way that there is an adequate clearance angle in the working position of the thread-milling tip and it can nevertheless be provided with an optimum rake angle. This is achieved by the end face of the thread-milling tip having a circular reduced portion. <IMAGE>

Title: Special harvesting bucket
Inventor: LOHSE HEINZ
IPC: A45F5/00
Filed: 1988-03-15
Abstract: For the fruit harvest, baskets, buckets or similar containers have previously been used. If the abovementioned harvesting aids are used on a ladder, the fruit harvesting becomes, because only one hand is free, a dangerous balancing act as is borne out by accident statistics of the trade associations. The special harvesting bucket is made of PVC and is worn around the neck in front of the body with a continuously adjustable strap. By these means, the special harvesting bucket is always conveniently reachable during picking and both hands are free, as a result of which the safety on the ladder is considerably increased. The design of the hanging strap (6) with a hook (5) as well as carrying handles (2) with half-eyes (4) make possible very practical handling during hooking on and unhooking (which is carried out by lifting with both hands at the sides, the carrying handle being held firmly also). Emptying also is very convenient as a result of the gripping strip on the bottom part (9). The special harvesting bucket is an ideal harvesting aid and designed especially for the small gardener, domestic gardener and hobby gardener as it is universally usable for all types of fruit (hard and soft fruit). <IMAGE>

Title: Brake valve for delaying the lowering movement and positioning of the working piston of a cylinder/piston arrangement
Inventor: VOSS WALTER
IPC: F15B13/01
Filed: 1988-03-31
Abstract: A brake valve with a differential piston, a pressure-medium inlet bore and a pressure-medium outlet bore with which the differential piston forms a main valve. Arranged upstream of the differential piston is a control piston which actuates a control valve. The differential piston has a coaxial orifice bore, adjoining which is a control bore with a control chamber in between. The control bore leads to the control valve. The actuation of the control piston, which is acted upon by an adjustable compression spring, is effected via a pressure-medium feed bore and a pressure-medium return bore which, like the pressure-medium inlet bore and the pressure-medium outlet bore, can be attached to a cylinder/piston arrangement having a working piston with a multi-way valve in between. The brake valve works as overpressure protection, relief valve and non-return valve and in addition serves to position the loaded working piston. A pilot-controlled brake valve is realised in which the working part with the differential piston and the control part with the control piston are mechanically separate from one another. <IMAGE>

Title: Process for the preparation of methyl tert-butyl ether from n-butenes
Inventor: GAILLARD JEAN-FERDINAND
IPC: C07C41/06
Filed: 1988-04-22
Abstract: A process is described in order to obtain methyl tert-butyl ether, starting from a charge of n-butenes. The process includes a stage of structural isomerisation (20), at least one fractionation stage (22) in order to obtain a fraction which is enriched in isobutene and butadiene, one stage of etherification (23) of this fraction with methanol (9) and one stage of fractionation (24) in order to obtain methyl tert-butyl ether (10) and a residual fraction (11) which is depleted in isobutene and contains butadiene. This residual fraction is then fed to a zone of selective hydrogenation (25) in such a way that an efflux is obtained which contains 100 to 800 ppm of butadiene which is returned to the zone of structural isomerisation (20) and the use as fuels for automobiles. <IMAGE>
Patent DE-3819165-A1 (DE)
Title: Cast annular lid with concrete
Inventor: EICHELMANN HORST DIPL ING
IPC: E02D29/14
Filed: 1988-06-04
Abstract: There are lids for manhole covers made of cast iron with a cast-iron surface with fluting and lids of cast iron with concrete filling. In some cases, e.g. for design reasons, a lid with a cast surface is required. However, this lid is more expensive than a lid with concrete filling. The innovation shows lids of cast iron with a fluted cast surface with one or two reinforcing rings on the underside. To save weight, the entire annular space or the annular space between the outer and inner cast ring is filled with concrete. Concrete is a material which is especially suitable for absorbing compressive forces. When the lids are loaded, tensile stresses occur in the bottom cast-ring area and compressive stresses occur in the top concrete area. These compressive stresses in the concrete partly compensate for the tensile stresses in the bottom cast-ring area, since the concrete in the top area counteracts a deflection of the lid. This means that the cast ring or cast rings can be kept lower and thinner.

Title: Piston-connecting rod connection of a trunk piston internal combustion engine
Inventor: RIPBERGER EMIL
IPC: F16J1/16
Filed: 1988-11-11
Abstract: In a piston-connecting rod connection it is proposed that the force be transmitted as close as possible to the piston axis and confined to this area. For this purpose the piston bosses accommodating the piston pin are situated radially inwards and supported at the centre of the piston head, essentially independently of the piston skirt. The force-transmitting bearing surfaces of the small end and of the piston bosses are designed with different sizes on the piston head and piston foot sides. A central, narrow, annularly enclosed small end section alone serves to absorb the inertial forces of the piston in its upwards movement, the small end altogether comprising only one piece.

Title: Internal combustion engine
Inventor: OETTING HERMANN DR
IPC: F02B1/04
Filed: 1988-11-17
Abstract: An internal combustion engine (1) is described with at least one piston (3) sliding in a cylinder (2) and with a working chamber of variable volume enclosed between the end wall (11a) of the piston (3) and a cylinder head (4), which chamber close to the top dead centre of the piston forms a combustion chamber (5), in which the cylinder charge, composed of a fuel-air mixture, is ignited and burnt. In order to improve and even out the ignition and the combustion, it is proposed that a body (12) of a highly heat-resistant material with low thermal conductivity and low head capacity be held on at least one wall (11) defining the combustion chamber (5). The said body (12) is preferably to be held on the end wall (11a) of the piston (3) in the area essentially lying axially opposite the spark plug (10), the body at least partially surrounding the spark plug (10) in the area of the top dead centre of the piston (3). <IMAGE>

Title: Installation for the decentralised, all-embracing energy supply, preferably of households
Inventor: MARTENS JOERN
IPC: F03D9/25
Filed: 1989-01-19
Abstract: The invention relates to an "installation for the decentralised, all-embracing energy supply, preferably of households", that means, in this case, that all energies needed in the relevant (private) household, including the indirectly generated energies, are generated by this installation and can also be stored, in various intermediate stages. Primary energy sources are in this case wind energy and the energy of sunlight (solar energy/photovoltaic). It would, however, also be possible to use other energy sources if these, for example water power, were available favourably in the relevant case. The installation has a plurality of energy stores which make uniform the energy supply and make possible the coverage of peak loads. The provision of energy and the use of energy are thus made uniform, and thus the supplying of the relevant household is ensured, for the generated quantities of energy correspond to those consumed in the case of correct dimensioning of the installations, at least when viewed over a relatively long period of time. An available power is thus distributed and stored in such a way that as much work as possible can be carried out therewith. Elements for room heating and the kitchen equipment, developed specially for saving energy, ensure a balanced energy balance of the installation. <IMAGE>

Title: Reduction of the noise from laser transmitters
Inventor: SCHICKETANZ DIETER DR ING
IPC: H01S5/068
Filed: 1989-04-03
Abstract: In the case of laser transmitters, the laser noise can increase as a result of reflection to such an extent that the transmission is interfered with, particularly at high bit rates and with wide bandwidths. The invention proposes that the laser noise be minimised by setting a specific separation between the laser diode and the input optics or fibre ends, the minimising being achieved by means of a temperature change of the laser module. This is enabled in a simple manner by an actuating signal which is dependent on the laser noise being produced and by this signal being passed to the temperature regulator of the Peltier cooler contained in the laser module.
