Patent DE-3808559-A1 (DE)
Title: Method and device for monitoring the power limit of a starter battery
Inventor: HERLT RAINER
IPC: G01R31/36
Filed: 1988-03-15
Abstract: In a method and a device for monitoring the power limit of a starter battery, particularly in motor vehicles, a lower terminal limit voltage is calculated in dependence on a measured temperature and a particular discharging current of the starter battery, taking into consideration battery-specific parameters. This terminal limit voltage is compared with a measured terminal voltage and a warning device is activated when the terminal voltage is less than the terminal limit voltage. To increase reliability in the monitoring and indication of the power limit of a starter battery and for reducing the output of false alarms, the warning device is only activated when the terminal voltage is less than the terminal limit voltage over a predetermined period, and the warning device is only switched off when the accumulated charge quantity is greater by a predetermined amount than the charge quantity lost.

Filed: 1988-05-31
Abstract: 2.2 In the method according to the invention, a corner connector or T-connector (3) is provided in the areas of the joint with at least one depression or one perforation (13), introduced into the inner cavity of a plastic section member (8) or a transom member, and the wall of the frame or transom member which lies adjacent to the depression or perforation in the connector is plasticised by means of a heated stamp, and the plasticised material is pressed into the depression or perforation in the connector by means of an embossing stamp and cooled to the solidification temperature. The possibility also exists of using a connector which is made from thermoplastic material, in which case both the material of the wall of the frame or transom member and a part of the adjacent material of the wall of the connector are plasticised by means of a heated stamp. An embossing stamp is then used to combine the plasticised materials of the walls of the profile and of the connector, under compressive stress, and they are cooled to the solidification temperature. <IMAGE>

Title: Nitrogen washing of ammonia synthesis gas - starts at prodn. process with double distn. stage
Inventor: BAUER HEINZ DIPL PHYS DR
IPC: C01B3/50
Filed: 1989-08-03
Abstract: CO and/or Ar are produced by pressurised low temp. washing with liq. N2 of NH3 synthesis gas consisting of H2,N2,CO and impurities which include Ar. At least part of the washed liq. output stream is split into prod. streams in a multi-zone deep temp. distillation column. In a first output stream the head fraction is partly condensed by heat exchange with liq. N2, while the sump fraction is partly evapd. by heat exchange with  condensing gaseous N2. This produces a CO-rich stream and a sump prod. contg. liq. Ar, which is treated by a further distn. process to form a liq. Ar stream. ADVANTAGE - Division into two deep temp. distn. zones permits prodn. of high purity Ar, and the simplified method uses same N2 stream to cool both head and sump.

Title: Inhibiting oxidn. of carbon fibre reinforced carbon moulding - by chemical vapour infiltration or deposition of pyrolytic carbon and opt. silicon carbide
Inventor: PAPENBURG ULRICH DIPL ING
IPC: C04B41/52
Filed: 1989-10-04
Abstract: Prodn. of carbon-fibre reinforced carbon mouldings protected against oxidn., the mouldings of any geometrical shape, produced by moulding and carbonisation in conventional manner, which have a C fibre-reinforced porous C-C matrix, are subjected to chemical vapour phase infiltration (CVI/CVD) with pyrolytic carbon, so that each individual C fibre or fibre bundle is sealed with a dense protective C layer. The density (1.2-1.8 g/cc) and open porosity can be regulated by the amt. of pyrolytic C infiltrated and/or the reaction time of the CVI process. The moulding may then be infiltrated or filled by CVI or CVD with SiC or infiltrated with liquid Si (alloy) and opt. finally reacted with N2 to convert the free Si to Si3N4 to give a multilayer effect increasing the long-term resistance to oxidn. and wear. The process can be carried out with 1-, 2- and 3-dimensional mouldings and mouldings consisting of short fibres (random and quasi-isotropic) and felts. Pref. resins matrices for making the mouldings are phenolic resins, silicone resins and/or resins contg. Si-C, Ti:and/or W. The resin content is 10-50 wt.% w.r.t. C fibres. The gas-tight pyrolytic C coating is 10-3000 microns thick. An inert sepg. layer may first be produced on the fibres (bundle) by CVI, pref. with BN or AIN. ADVANTAGE - The treated moulding has good resistance to oxidn., extremely low porosity, characteristic texture, high purity and an esp. high flexural strength of min. 300 N/mm2 at a density of 1.2-1.8 g/cc and also an E modulus of min. 90 GPa (claimed). The purity can be extremely high, at under 5 ppm, which completely eliminates out-gassing (claimed). The moulding has good resistance to O2 up to over 1800 deg. C, in conjunction with high strength and pseudo-plastic fracture.
