Patent DE-4207038-A1 (DE)
Title: Connection to existing main drain by new pipe - where seal is formed by inverting resin soaked packing into joint and holding under pressure until hardened
Inventor: SCHREINER HERBERT
IPC: E03F3/06
Filed: 1992-03-06
Abstract: The main drain pipe (1) has a branch pipe (3) connected to it. A seal is made between the two by a resin soaked collar and insert (16,18). The insert is aligned flush with the branch line opening (10) and then inverted by pressure into the branch line. The pressure is maintained until the resin cures to form a water and air tight joint.A rubber mantle is used to seal the joint against air or liquid leakage. USE/ADVANTAGE- Form connections between new branch lines and existing main sewer.

Title: Automatic tracking for video recorder with inserted time reference - picking up defined change in signal series in period before and/or after useful signal gaps
Inventor: KAADEN JUERGEN DIPL ING
IPC: G11B5/588
Filed: 1992-04-15
Abstract: The tape recording format consists of diagonal tracks of width 18 mm at an angle of 6 deg. (alpha). A reference signal is generated by the video recorder head drum, and the time difference (t1) from this w.r.t. a synchronising signal in the recorded data is used to control the automatic track following (ATF) circuit. The synchronising signal is a transition from f1 to f2 in the recorded data, which may be a phase of frequency transition. The time error (delta t) in the case of a 50 per cent tracking error is about 6 microseconds. The synchronising signal is introduced by the recording circuitry. USE/ADVANTAGE - Used for HDTV recorders, avoiding loss of recording during separate synchronising signal. Not based on amplitude evaluation of ATF signals. Requires only small additional recording surface for ATF signals. Gives sufficient track regulation for even small deviations.

Title: Mfg. metal-oxide semiconductor MOSFET - depositing insulating film on substrate of first conductivity type and etching both film part and substrate to preset thickness
Inventor: SHIN HYUNG SOON
IPC: H01L29/78
Filed: 1992-04-16
Abstract: A substrate of first conductivity type is coated with an insulating film, whose preset part is etched, together with the substrate to a preset thickness to form in it a depression. Then a second insulating film is grown on the entire exposed surface of the first insulating film and substrate.

The remaining first insulating film is removed, and a third such film is formed on the exposed substrate and gate electrode surface, followed by drain and source regions of low concentration of second conductivity. The gate electrode is surrounded by a side wall and high concentraton drain and source regions are formed on the low concentration ones. ADVANTAGE - Overlapping n-regions of lower carrier concn. by deep set gate type reduces capacitance and size as well as effects of doping of MOSFET.

Title: Process for recovering metal from scrap sheet
Inventor: WESTERMANN HANS-HEINRICH
IPC: C22B7/00
Filed: 1993-02-25
Abstract: In a process for recovering metal from scrap sheet which is contaminated by paints containing heavy metal compounds, in particular from scrap metal packaging containing paint residues, and for disposal of the heavy metal compounds or heavy metals, the scrap sheet is introduced into a metal-melting furnace and molten to give a melt. The melt is mixed with a slag liquefier which contains fluorspar (CaF2) or consists of fluorspar, which forms a slag with the heavy metal compounds and/or the heavy metal of the heavy metal compounds. The fluorspar content is adjusted such that a slag is formed which can be dumped in landfills for building rubble. The temperature of the melt is adjusted such that the slag settles as a surface layer on the melt which has been mechanically smoothed. The still liquid slag is then decanted and, after solidification taken to a landfill for building rubble, and the metal is taken to re-use.

Title: Method and arrangement for signal transmission between an audio device and a telephone device
Inventor: JAHN ALFRED
IPC: H04H60/80

Patent DE-4315952-A1 (DE)
Inventor: STALTMEIR ANTON
IPC: A62B1/06
Filed: 1993-05-12
Abstract: An ascending and descending device for lowering and raising persons or loads on a rope, having an abseil pulley (2) around which a rope (1) is wound and which is arranged on a supporting pin (5) so as to be freely rotatable in the one direction of rotation and locked in the other direction by means of a free-wheel and non-reversing lock in such a way that, when the load to be lowered on the rope acts on one end of the rope, the rope slides on the locked abseil pulley and the frictional force developing here brakes the load and, when a tensile force acts on the other end of the rope, the abseil pulley runs freely. The ascending and descending device is to be designed in such a way that incorrect positions of the rope windings can be eliminated so that the functional reliability of the device is improved. This is brought about by the rope pulley being enclosed by an essentially tubular component (3), the distance between the tubular component and the rope being less than the rope diameter, and the tubular component having two slot-like openings (7, 8) through which the two ends of the rope run. Here, the rope guide surfaces (9a, 9b) are conveniently arranged on the inside of the tubular component. In addition, the tubular component can contain a viewing slot which enables the number of rope windings to be checked. It is especially advantageous to form the tubular component from a transparent material. <IMAGE>

Abstract: A very compact and easy-to use wireless information transmission system of the internal corporate radio data transmission (radio data LAN) type has a standardised plug-in serial interface (15) which in each case can be plugged directly into small-housing radio modules (12) to receive or transmit data (18) and also a rod antenna (14) to transmit or receive the correctly coded data (18) in the VHF frequency range, so that, even when broadcast through buildings, no phase shifts occur which interfere with reception and revert to reflex phenomena. In addition to the transmitted data (18), an identifier (19) is transmitted to switch only specific contactable modules (12) to reception. The modules (12) can be plugged directly into the externally accessible serial interfaces (15) of computers (28, 30) or peripheral devices (32) and operated. The interface (26) in the module (12) can also be designed, however, to convert the information into a fax protocol in order to operate this module (12) when directly plugged into a fax socket (35). <IMAGE>

Filed: 1993-08-13
Abstract: In the case of an arrangement for determining the polarisation of electromagnetic waves by evaluating the amplitude and the phase difference of the signal components of two orthogonally polarised receive antennas, the two signal components are fed one after the other via a commutator to one input of a compensation mixer as measurement signal and a signal derived from the same wave to be measured is fed to the other input of the compensation mixer as reference signal, and the polarisation is then determined in an evaluation device from the real-part and imaginary-part components of the compensation mixer, which components correspond to the instantaneous phase difference and the instantaneous amplitude ratio of reference signal and measurement signal in each commutator circuit.

Title: Process and apparatus for biological waste water purification
Inventor: SEKOULOV IVAN PROF DR ING
IPC: B01D21/00
Filed: 1993-08-26
Abstract: The invention relates to a process and apparatus for biological waste water purification, in which process or apparatus water constituents are respired with feed of air or oxygen by bacteria suspended in the activated sludge/waste water mixture in an activation tank, and then the mixture and excess sludge being transferred (13) into a secondary clarification tank (12) in which the bacteria are separated from the water by sedimentation and are returned (14) to the clarification tank (10). It has become noticeable as a disadvantage in the previously known activated-sludge processes and apparatuses that a dry matter content of only about 2.5 to 5 g/l can be achieved in the activation tank, which greatly restricts the purification efficiency. The invention provides a remedy here by the biomass or bacterial content in the activation tank (10) being increased by lamella packs (18) arranged running inclined upwards and which are arranged at the end of the flow path of the activation tank (10) upstream of the outlet at a distance from the latter, or the activated sludge being thickened, so that in the activation tank (10) a dry matter content of > 5 to 7 g/l can be set (cf. Fig. 8). <IMAGE>
