Title: Oil feed with return prevention device for bucket tappets with hydraulic valve clearance adjustment
Inventor: REITZ JOHANNES
IPC: F01L1/25
Filed: 1984-06-08
Abstract: The patent application describes a bucket tappet with hydraulic valve clearance adjustment, which in addition to the reliable venting of the high pressure chamber by virtue of the sintered bushing (2) according to DE 2942926 A1, returns the oil displaced from the high pressure chamber as it drops by way of a bore (9) into the reservoir chamber (4).   a) By means of a diaphragm (14) Fig. 6, it is proposed to prevent oil from running out of the tappet when the engine is at a standstill. b) If the cam is in an unfavourable position, the diaphragm (14) is intended to catch the oil expelled from the high pressure chamber (11). This is done according to the position of the diaphragm between the limits (14 and 14a). The chambers R1 and R2 are thereby formed. c) When starting up again, the oil in the chamber R2 is fed directly to the high pressure chamber (11) by way of the high pressure piston. If, in the process, air passes initially from the oil supply duct (13) into the oil reservoir chamber (4), only the chamber R1 is affected by this. The amount of oil from R2 is generally sufficient to fill the high pressure chamber. This is sufficient for starting. d) Finally an entirely closed system is possible by means of the innovation described.   The description is aimed at silent starting of the valve gear with the minimum or no tappet oil requirement, so that the risk of contamination and polymerisation is reduced or excluded.

Title: Door case, in particular rebate lining with metal subconstruction, welded in the mitre
Inventor: FINK WERNER OTTO
IPC: E06B1/34
Filed: 1984-11-22
Abstract: The careful renovation of doors has until now been relatively extensive; all door elements present were removed, including door frame. A new frame was built onto the masonry and a new door inserted. This method is expensive and often leads to consequential damage which is not to be underestimated. More simple possibilities have been sought:   1. Lining the existing door - the disadvantage is that doors thus renovated do not look completely genuine. 2. Construction of a dimensioned lining with a screw-on band which is turned over the existing lining. Disadvantage: the stop region is displaced by the wall thickness of the rebate lining - possibly different floor coverings become visible. A thin-walled rebate lining is thus necessary. The required mechanical stability of the door can, however, not be achieved if only wood is used as construction material.   The use of a thin-walled metal reinforcement (e.g. aluminium) avoids the abovementioned, expensive shortcomings.

Title: Method and configuration for determining the properties of rocks
Inventor: DANNENBERG FRIEDRICH KARL DIPL
IPC: G01N33/24
Filed: 1985-03-01
Abstract: A method and configuration for determining the properties of rocks are proposed in which a sample of the rock is insonified with ultrasonic waves in three directions - which are preferably perpendicular to one another - and by measuring the time and the path, the speed of sound in the rock is measured. The values thus determined are compared for the three directions with values of known rocks. For each direction, a plurality of measurements can be carried out, randomly distributed over the rock face. More extensive, wider-ranging, more accurate and more fundamental information can be obtained on rocks than by using conventional methods. The method according to the invention provides a very broad, general information spectrum, requires little time and causes little cost.
Patent DE-3509336-A1 (DE)
Title: Optical time domain reflectometer with heterodyne reception
Inventor: KNOECHEL REINHARD DR
IPC: G01M11/00
Filed: 1985-03-15
Abstract: The invention relates to an optical time domain reflectometer for determining the attenuation of an optical fibre by measuring the back-scattered component of light pulses transmitted into the fibre. If the receiver is constructed in accordance with the heterodyne principle, drifting of the frequency of the transmitting laser causes a substantial deviation in the intermediate frequency over the narrow bandwidth of a filter. In order to avoid this disadvantage, it is proposed that a light beam (6) branched off from the light (1) of the transmitter (L) is led into a frequency discriminator (FD) which forms an electrical signal (SL, S'L) which is independent of the optical frequency and is fed to a comparison circuit which compares the signal SL received during the transmission time  tau S and the signal S'L received during the receiving time  tau E following thereupon and converts it into an electrical difference signal Sd whose magnitude corresponds to the difference of the laser frequencies, and that there is superimposed on the output signal SD of the optical receiver (D) a compensation signal SK whose frequency is proportional to the electrical difference signal and is adjusted in such a way as to produce the value (fL-f'L), fL being the optical transmitting frequency during the transmission time  tau S, and f'L being that during the receiving time  tau E. <IMAGE>

Patent DE-3517178-A1 (DE)
Title: Process for producing nodular cast iron
Inventor: BRANDENBERGER URS DIPL ING
IPC: C21C1/10
Filed: 1985-05-13
Abstract: A process for producing nodular cast iron is proposed, wherein the treatment of the molten iron is carried out with metallic magnesium. By addition of CaSi, the sulphur content of the unstable compound MgS in the slag is converted into the stable compound CaS. This prevents a return of the sulphur, released from the compound MgS during prolonged standing times, back into the melt and a reaction therein with the dissolved magnesium, forming Mgs anew. The binding of the sulphur in the slag itself effectively prevents resulphurisation. The slag can remain on the surface of the melt for a prolonged period and has a heat-insulating effect, so that any longer standing times, caused by production conditions, can be accepted.

Title: Sterilising filtration process and water sterilisation apparatus therefor, in particular having a sterilising filter and/ôor a fine clarifying filter
Inventor: GRUNDMANN PETER WALTER
IPC: B01D29/00
Filed: 1985-09-24
Abstract: The invention "sterilising filtration process and water sterilisation apparatus therefor, in particular having a sterilising filter and/ôor a fine clarifying filter" makes possible a simplified water treatment. In this case, even a "sterilising filtration" is possible without complex pretreatment of the raw water in a pretreatment bag, possibly after dissolution of added chemical agents, by pumping the raw water through fine clarifying filters and sterilising filters. According to the invention, raw water is pumped from a small vessel through a coarse filter and fine clarifying filter and/ôor sterilising filter in such a way that simultaneously to pumping raw water into the metering cylinder of the pump, to vortex this liquid standing in the sterilising filtration vessel and now to be filtered, liquid, which was sucked into a storage space during the preceding pressure stroke, is passed into this. The introduction or suction of these liquids preferably takes place in this case in the vicinity of the vessel bottom, opposing liquid streams forming in circulation above this. As a result of the vortex flow forming in the raw water above the vessel bottom or upstream of the feed to the metering cylinder of the pump, the pump remains functional and a solution of the chemicals possibly added to induce freedom from bacteria and a good mixing of the raw water occur.
