Patent DE-3905128-A1 (DE)
Title: Fully bonding rope anchor
Inventor: NORKUS HANS
IPC: E21D20/02
Filed: 1989-02-20
Abstract: In rope anchors placed to improve the stability of strata, bonding over the entire length is ensured, since the rope body encloses a rope core forming a hollow tube, carries a non-return head at the back of the borehole and has a threaded piece to which a connection for a pump hose is allocated. Resin material is injected through the rope core, comes out at the back of the borehole and from there uniformly fills the entire hollow space between borehole wall and surface of the rope anchor. By distributed bores and passages in the rope anchor, a discharge of the resin material can also be specifically ensured here at various further locations. Owing to the fact that a connection is created for a pump connection and in the process preferably with plug-type connection, it is possible to inject the resin material into the borehole at an appropriately high pressure. <IMAGE>

Title: Data output buffer circuit for byte-wide memory
Inventor: LIM HYUNG-KYU
IPC: H03K17/16
Filed: 1989-03-31
Abstract: An output buffer circuit for a byte-wide memory is described. The circuit has a circuit (Mdep1, Mdep3) to delay the rising or falling time of the gate voltage of a pull-up transistor (Mpu3, Mpu4) of an output driver (OD). The circuit (Mdep1, Mdep3) is arranged between a p-channel transistor (M9, M13) and an n-channel transistor (M10, M14) of the pull-up inverter (I1, I3). The circuit has another circuit to delay the rising time of the gate voltage of a pull-down transistor (Mpd3, Mpd4) of the output driver. This is arranged between a p-channel transistor (M11, M15) and an n-channel transistor (M12, M16) of the pull-down inverter (I2, I4). The described delay circuits may include a depletion transistor (Mdep1, Mdep3, Mdep2, Mdep4), the gate and source of which are connected to each other. By providing such delay mechanisms, generation of noise on both voltage and earth lines can be reduced. <IMAGE>

Patent DE-3929079-A1 (DE)
Inventor: DREIZLER HELMUT PROF DR
IPC: G01N22/00
Filed: 1989-09-01
Abstract: In a procedure for analysing gaseous media, in particular for determining the concentration of a gas in a gas mixture, by means of microwave spectroscopy, the microwave radiation is coupled in pulsed form into a resonator which can be tuned to different frequencies and which is situated in an evacuated receiving vessel. The gas mixture to be examined is admitted as a pulsed molecular beam into the receiving vessel using air as carrier gas. The mixed state formed by the microwave pulse produces an emission which, during the intervals in the incident microwave pulses, is coupled out from the resonator into a receiving unit. After down-conversion to frequencies preferably in the region below 50 MHz, the test signal is digitised and evaluated, during which process a Fourier analysis may be carried out.

Title: Convective heat treatment unit for e.g. semi-finished wire - uses gas steam for rapid cooling of wire positioned transverse to flow in venturi-line guide
Inventor: KRAMER CARL PROF DR ING
IPC: C21D9/573
Filed: 1989-10-27
Abstract: Convective heat treatment unit, esp. for rapid cooling of cylindrical semi-finished products e.g. wire, in a gas stream has the novelty that the product is moved in the direction of its longitudinal axis transverse to the gas flow in the region of the narrowest flow cross-section through a flow guide which at first narrows and then broadens out. The inlet and outlet cross-sections are approximately equal; more specifically the ratio of the outlet and outlet cross-section to the narrowest cross-section is between 2:1 and 4:1 or 3:1. The flow guide is two-dimensional with the semi-finished product positioned in the direction of the third dimension. ADVANTAGE - The flow design coupled with the use of gas avoids the environmental impact of existing treatment systems based on e.g. lead baths.

Title: Prepn. of extracts of rhizoma petasitidis - by extraction with compressed carbon di:oxide and subsequent sepn. of the extract by reducing the density
Inventor: ZOBEL RUDOLF
IPC: C07C67/58
Filed: 1990-02-01
Abstract: The prepn. of an extract of Rhizoma petasitidis with a low content of pyrrolizidine alkaloids comprises extracting the drug with condensed CO2 and then separating the extract from the solvent by reducing the density. The extraction is pref. carried out at 100-300 (esp.  130-260) bar, and at 25-45 (esp.32-40) deg.C. Pref. 5-50 kg CO2 are used per kg starting material. The sepn. of solvent is pref. carried out at 30-50 bar and 10-30 deg.C. The water content of the extract is pref. removed by drying. USE/ADVANTAGE - The process can be used to prepare an extract from the petasites rhizome which contains high yields of the spasmolytic Petasin as main ingredient (up to 40%) and which has a low content of pyrrolizidine alkaloids (no more than 1ppm) such as senecionine. Compared to the original drug, the pyrrolizidine content is reduced by at least 95% and the yield of petasin is at least 90%. The process is less technically complicated than previous processes using alcohol and cation exchangers, in which, on account of the temp. sensitivity of the petasin the sepn. of alcohol and water poses problems.
