Title: Pharmaceutical preparations in retard form - with active materials in core having semipermeable coating of film former and polymer
Inventor: STRICKER HERBERT DR
IPC: C07D498/04
Filed: 1978-07-15
Abstract: Pharmaceutical prepn. in retard form comprises a core contg. >=1 active substance together with a carrier or excipient. The core is coated with a semipermeable coating of 20-90% water-insoluble film former (I) (e.g. ethyl cellulose) and 10-80% water-soluble polymer (II), e.g. PVP, PEG or methyl cellulose. The release of active substance is independent of pH in the body fluid over the whole period of its activity. The core pH may be reduced by inclusion of acidic material to reduce disintegration time. Dosage regimens are simplified, and initial very high blood levels may be avoided. The core may be in the form of a tablet. The coating pref. has the same permeability over its whole surface. The core may contain an organic food acid to reduce the disintegration time of the core, e.g. citric or tartaric acid is used. The coating may also contain up to 70% water insol. polymer e.g. cellulose acetate.

Title: Heat dissipating pipe for underground power cables - is installed with cable and wholly buried to distribute heat over earth
Inventor: ROHNER PETER DR RER NAT
IPC: H01B7/29
Filed: 1978-07-27
Abstract: A heat conductive pipe removes heat dissipated by underground power cables to achieve a more intensive cooling without servicing or any above ground installations. One end of the pipe is attached to, or near, the cable while the other end is placed some distance away in the soil. Heat is thus transferred away from the cable, and the isotherms in the soil made to follow a more favourable pattern. The pipe is, with advantage, made as a meander with successive hot and cold sections.

Patent DE-2911679-A1 (DE)
Inventor: BERGMANN KURT WERNER DIPL CHEM
IPC: D21H19/60
Filed: 1979-03-24
Abstract: A method for the coating of a raw paper or cardboard substrate wherein the substrate is prepared having a pH of less than about 6.5, and a coating is applied thereto composed of an aqueous dispersion of a plastic and an inorganic pigment, the coating having a pH of more than about 6.5 wherein the particles of the plastic in the dispersion have a non-cation-active charge and wherein the coating also contains a material which does not affect the preparation or storage stability of the coating, but which in the pH range below about 6.5 becomes highly cation-active, and then drying the thus applied coating. Using this method, the coating solidifies at the time of contact of the coating and the paper surface thereby minimizing penetration of the coating into the paper. As a result, improved coated papers are obtained.

Title: Moisture supervision of telephone cables with synthetic insulation - employing moisture sensitive material separating two conductors connected to insulation resistance monitor
Inventor: ROHNER PETER DR RER NAT
IPC: H01B7/32
Filed: 1979-03-24
Abstract: The appts is for telephone cables employing synthetic insulation on the individual conductors, and having transposed cores. In order to detect the presence of moisture, for example due to damage to the cable sheath, two conductors in the cable are insulated with a moisture sensitive material. When the cable is installed the two conductors are connected to an insulation resistance monitor which indicates a low reading if moisture is present. A variety of materials are suitable for the special insulation. Examples are salts or mixtures which form an electrolyte in the presence of water a felt material with high absorbent properties, or paper. Without the appts. as described the entry of moisture into a cable with synthetic insulation is difficult to detect before it enters a jointing box.

Title: Optically active alpha-substd. alanine and glycine derivs. prodn. - from optically active alanine and glycine or their alkyl ester(s) by asymmetric synthesis via piperazine-2,5-di:one cpds.
Inventor: HARTWIG WOLFGANG DR
IPC: C07D241/08
Filed: 1979-08-24
Abstract: New processes are claimed for the prodn. of pure or substantially pure optically active alpha-aminoacid derivs. of the formulae Me-C(R1)(NH2)-COOR' (Ia) and R1-CH(NH2)-COOR' (Ib) in which R1 is a non-aromatic organic residue and R' is H or 1-4C alkyl. The first step in the prodn. of (Ia) comprises self-condensation of pure or substantially pure optically active alpha-alanine or its 1-4C alkyl ester to give (R,R)-3,6-dimethyl piperazine-2,5-dione (IIIa) or (S,S)-3,6-dimethylpiperazine-2, 5-dione (IIIb). The first step in the prodn. of (Ib) comprises reaction of glycine or a glycine 1-4C alkyl ester with a pure or substantially pure optically active alpha-methyl-phenylalanine deriv. of the formula Me-C(R2)(NH2)-COOR' (IIc) (where R2 is benzyl opt. substd. in the phenyl residue) to give a 3R- or 3S-3-methyl-3-R2-piperazine-2, 5-dione (IIIc) or (IIId); alternatively, (IIIc) or (IIId) may be prepd.via the corresponding open chain dipeptides by conventional methods. Subsequently, (IIIa)-(IIId) are reacted with an alkylating agent to give a corresponding 2,5-di(1,4-C alkoxy)-3,6-dihydropyrazine deriv.(IVa-d). This is reacted at least an equivalent amount of a strongly basic organometallic cpd. to give a deriv. of (IVa-d) monosubstd. in the 6-position by the metal of the organometallic cpd., and the metal deriv. is reacted with a cpd. R1-Y(V) (where Y is a residue which can be split off as an anion). The resulting deriv. of (IVa-d) substd. in the 6-position by R1 is hydrolysed by means of an acid, and (Ia) or (Ib) is isolated from the hydrolysis mixture by conventional methods. Also claimed are corresponding 2,5-dialkoxy-3,6-dihydro-pyrazine derivs.

Title: Roof suspension bracket for cable pipes - has open base for top bolt access and contoured sides with overlap base plus bolt fixing
Inventor: MUELLER FRANZ
IPC: F16L55/035
Filed: 1979-11-22
Abstract: The design is for easy installation of the top bolt for suspension and the access to it for tightening etc. when the bracket has been closed. The bracket has a top mounting hole (15) for the suspension bolt (22). The top plate (16) of the bracket is flat with side plates (17) curving away to the bottom sections (11,13) which overlap. When the bracket is closed the top first angle (19) on either side of the suspension bolt (22) pulls into a right angle, the bottom parts (11,13) overlap with one at the bottom (13) and the top one (11) carrying a threaded centre section (12). The overlapping bottoms may be soldered or sweated together. When closed the sides (17) are symmetrical to ensure even loading on the suspension bolt (22). The outer (13) bottom plate also has a hole (14) which coincides with the threaded one (12) in the other base. A second unit can be bolted below using the threaded (12) base for fixing. A catch (25,26) prevents the bottom (11,13) springing apart when it is being assembled. All holes can be vibration damped with bushes if required.
