Inventor: HERRLING SIEGFRIED DIPL CHEM D
IPC: C07D513/04
Filed: 1977-03-24
Abstract: New medicaments contain as active substance one or more pyrimido-thiadiazole derivs. of formula (I) and/or pharmaceutically utilisable salt thereof. In (I), R is H, a pharmaceutically utilisable cation, or 1-5C alkyl; and R1 is H, 1-5C alkyl; aralkyl, phenyl, thienyl or pyridyl opt. substd. by halogen, 1-4c alkyl or 1-4c alkoxy; or 5-7c cycloalkyl. Cpds. (I) in which R1 is other than CH3, and their pharmaceutically utilisable salts, are claimed as new cpds. (I) bring about a marked stimulation of the immune system and are useful in the treatment of diseases where an increase in the body's defence mechanisms is required, e.g. in viral infections, bacterial infections, systemic lupus erythematosis, tumours (e.g., to inhibit metastases), etc. Specific cpds. (I) include 7H-1,3,4-thiadiazolo 3,2-a -pyrimidin-7-one-5-carboxylic acid methyl ester. In an example, this was prepd. by reacting 2-amino-1,3,4-thiadiazole (10.1g.) in tetrahydrofuran (100 ml.) for 3 days with dimethyl acetylenedicarboxylate (14.2g.).

Title: Guide for cutting lengths of paper, plastics etc. from rolls - has cutting knife fixed to block sliding on transverse bar
Inventor: KIRCHNER HANS-MARTIN
IPC: B26D1/04
Filed: 1977-03-30
Abstract: Material such as paper, plastic film etc. which is sold in lengths to suit the customer is usually stored in large rolls and cut transversely as required. A square straight cut can be ensured by means of a board (1) which is bolted by its end flanges (11b) to the roll storage cupboard. The free end of the material is threaded under the spring loaded rollers (8) mounted on the shaft (7). The material is passed under the guide bar (14) and then clamped under the hinged strip (3). A knife (18) is attached to a block (16) which slides on the transverse guide bar (14). The blade of the knife can travel in a slot (2) in the board (1) and so cuts through the material as it is pushed along the length of the slot.

Title: Three=dimensional integrated circuit prodn. - has epitaxially grown substrate with components produced by alternate doping
Inventor: KRAUSE GERHARD
IPC: H01L27/06
Filed: 1978-07-20
Abstract: The integrated circuit consists of an epitaxially grown semiconductor substrate, contg. elements produced by doping, both on its surface and inside. The epitaxial and doping steps are alternated, in order to obtain a high precision for positioning the individual elements, as well as good reproducibility of the individual doping gradients. Pref. the alternating epitaxially and doping steps are separated by an interval of approx. one min. The doping is typically ion implantation in structured steps, typically controlled by a computer. In such instance an ion-optical mask is used. A temp. gradient may be generated orthogonally to the treated substrate surface which thus becomes hotter than the other one.

Title: Open channel flow measurement with tidal effect compensation - using characteristic function dependent on fluid level in channel
Inventor: RUDOLFSEN ING GRAD ALFRED
IPC: G01F1/34
Filed: 1979-08-30
Abstract: The appts. is used for determining the flow in open channels applicable to tidal systems. They enable the effects of tidal time variations in flow to be easily accounted for. The drop in fluid level and the level at a reference are measured in a channel section of constant flow cross-section and held in memory. The flow in the channel is then derived by computer from the measured values and a typical flow function for the channel which is fluid level dependent. The flow is determined from the speed, a roughness factor, the hydraulic radius, the flow cross- section and the drop in the channel. The channel characteristic function is found empirically.

Patent DE-2945621-A1 (DE)
Inventor: STOEBI JOHANN
IPC: D06B17/02
Filed: 1979-11-12
Abstract: Arranged at the web-entry and at the web-exit end of a J-shaped dwell chamber are drawing units (7, 31) which move a textile web (B) continuously through the dwell chamber (14). A single apparatus (13) causes, on the one hand, the plaiting of the web supplied and, on the other hand, the subdivision of the plaited web into bundles which then pass intermittently into the dwell chamber (14). This apparatus (13) comprises two flaps (32, 33) pivotably mounted opposite one another at the entrance to the dwell chamber (14). By means of a switching unit dependent on time, on web length or on web weight, the flaps can be pivoted out of a closed position, in which they project into the dwell chamber in a funnel-shaped manner and in which they plait a specific web length supplied to them and retain it in the form of a bundle, into an open position. In the latter, the flaps bear against opposite walls (2, 5) of the dwell chamber (14) and thereby release the web bundle. This falls under its own weight onto the web stack located in the dwell chamber and has an equalising effect on the folding of the latter. <IMAGE>
