Title: Process and apparatus for treating organic waste products made of solids and liquids, in particular slurry (liquid manure)
Inventor: LANGER PAUL G
IPC: C12M1/107
Filed: 1988-12-24
Abstract: In a process for treating organic waste products made of solids and liquids, in particular slurry, to reduce the throughput times and to achieve high quality biogas and highly growth-promoting fertiliser which can be applied during the growth phases it is provided that in a first stage, the fresh waste products, in particular the fresh slurry, are first introduced into a hydrolysis reactor (6) and stored and the gases forming, in particular CO2 and H2S, are taken off, and only then fed to a solids separator (10) and are brought in a second stage into a fixed-bed continuous flow reactor (14) where essentially methane gas is taken off. <IMAGE>

Title: Process and installation for producing hollow bodies from building material mixtures, preferably concrete mixtures
Inventor: GABLIA JURIJ ALEKSANDROVIC
IPC: B28B21/38
Filed: 1989-02-08
Abstract: The process is characterised in that the distribution of the mixture in a ready-assembled mould (3) takes place by the movement of a cavity former over the feed zones, starting from the end face away from the supply of the mixture, and the compaction is performed in two stages, first of all zone by zone in the feed zones at a pressure of 0.1 to 0.6 MPa and, after filling of the mould (3), by impulse action of an additional pressure of correspondingly 0.2 to 0.8 MPa. The installation for realising the process includes an injection device (1) and a mould (3) with a cavity former, which has an inner, axial cavity (A). The cavity former is made up of two coaxial sections, of which one serves as a stabiliser (11) and the other serves as a distributor (10). The latter has on the side face openings (''b), which are connected with the aid of channels (13) running at an acute angle with respect to the longitudinal axis of the installation to the inner, axial cavity (A) of the cavity former, which in turn is in connection with the injection device (1). <IMAGE>

Title: Method and device for optical data traffic
Inventor: TAKADA HIROHISA
IPC: H04B10/2587
Filed: 1989-02-22
Abstract: In a system for optical data traffic, a central station (20) is used which transmits light in both its transmitting and receiving modes. However, the transmitted light is unmodulated during the receiving mode. It is reflected, in modulated form, by a secondary station (35). This arrangement requires no more than one secondary station, which does not have its own light source. The reflected light is modulated, for example, with a liquid crystal display. The secondary station can then be very small, e.g. no bigger than a cheque card. In order to simplify the adjustment between the central station (20) and a secondary station (35), the reflector in the secondary station preferably contains a directional reflector, i.e. an optical component which reflects light beams essentially in the direction of incidence. A directional reflector of this type is also used advantageously in bar codes. <IMAGE>

Abstract: The invention relates to a method for manufacturing a tubular article, subjecting a thermoplastic material in the form of a powder or granules with the addition of chemical cross-linking agents as well as additives and auxiliaries to a high pressure in a pressure chamber, the temperature of the mixture increasing to about 110 DEG C, whereupon the mixture is passed through channels of an extrusion apparatus and heated to cross-linking temperature whilst still within the extrusion apparatus, the extruded hollow strand is drawn continuously through a moulding tool in the same working process and the hollow strand thus obtained is cut to length and, in order to produce a flange element with shaped head piece by means of a correspondingly designed mould, at least one end       a. is heated partially above the crystalline melting point, or b. is compressed under high pressure in the cold state (at room temperature), whereupon the heated or pressed hollow strand end permanently assumes the desired change in shape, and, to produce a flange joint from two thus-formed hollow strand ends (1, 2) with moulded-on flange parts, the shaped head piece of each flange element has an outer collar (3, 4) which is integrated with the hollow strand and the outside diameter of which is greater than the outside diameter of the hollow strand and which extends in the axial direction of the hollow strand beyond its end or is set back by this amount. In the fitted state of the flange joint, in each case a metal ring lies against the face of the outer collar running perpendicularly to the pipe body and the metal rings of the flange joint are pressed together with the aid of clamping elements. The outer collar (4, 5) of the shaped head piece of the hollow pipe strand or pipe end (1, 2) is designed as right-angled in cross-section or has an oblique face with respect to the pipe end. <IMAGE>

Patent DE-3933136-A1 (DE)
Inventor: FRAESSDORF DIETER DIPL ING
IPC: B04B3/00
Filed: 1989-10-04
Abstract: 2.1 A method in which two or more centrifuging stages situated spatially one above the other with intervening mashing are carried out in a common housing has not hitherto been possible in the case of highly viscous suspensions or/and suspensions which tend to form lumps. Such a method is used, for example, in the sugar industry, to treat the second sugar massecuite, and the object of the invention is to make it usable also for such highly viscous massecuites. 
<??>2.2 This object is achieved in that, before it enters the first centrifuging stage, the material to be centrifuged is viscosity-reduced and homogenised by the action of shearing force to such an extent that it can be fed to the centrifuging as a creamy massecuite and distributes itself uniformly on the screen of the first centrifuging stage. 
<??>2.3 This method is suitable for all highly viscous suspensions or/and suspensions which tend to form lumps, in particular in the sugar industry for treating the low-grade sugar massecuite, the so-called C sugar.

Patent DE-3935538-A1 (DE)
Inventor: KOBLITZ RUDOLF DR
IPC: H01L27/02
Filed: 1989-10-25
Abstract: In BICMOS circuits, the complementary MOS logic requires more transistor functions than does a I2L logic in bipolar circuits. By means of an improved MOS gate structure similar to that of I2L (CWL logic), the space requirements of the MOS logic are considerably reduced, while maintaining the noise-voltage sensitivity at the same level as in prior art CMOS logics. Because of the slower logic behaviour, the analog circuit structures are exposed to lower levels of noise radiation.
