Patent FR-2456731-A1 (FR)
Title: Guanidino and amino benzoate(s) and phenyl sulphonate(s) - and related cpds. inhibit protease(s) and have bacteriostatic and fungistatic activity
Inventor: CHOAY PATRICK
IPC: C07C279/18
Filed: 1979-05-16
Abstract: Substd.-arylamines and aryl-guanidines which inhibit protease (esp. serine-protease) activity and their enantiomers and acid addn. salts are new. Cpds have formula R1R2Ph-X-Y-Z (I), (where R1R2Ph-X- is known as the acylating part and -Y-2 as the acylated part of the molecule; R1 is opt. substd. guanidino (G) in position meta or para, primary amino in position meta or para, tert. amine having alkyl substituents in position para or nitro in position meta or para; R2 is alkoxy or when R1 is G then R2 may also be halo or alkyl in position meta or para according to whether the G gp. is meta or para; X is -CO- or -SO2-; Y is O, S or opt. substd. -NH-; Z is H (with the condition that when R1 is G it is in position 3 and that R2 is not halo in position 4), a cyclic group, esp. aryl (opt. substd. by guanidino, nitro or amino), a heterocyclic esp. opt. substd. pyrimidyl, morpholinyl or succinimide. R1 and R2 may also be H with the condition that they are not both H when Z does not contain a guanidino gp. Cpds. are protease inhibitors, which are particularly useful as inhibitors of serine proteases such as trypsin, plasmin and thrombin, bacteriostats and fungistats. (I) inhibit proteases by acylation of their active serine centre with the acylating part of the cpd., whilst the acylated part has excellent anticoagulant activity. The best bacteriostats have a lipophilic group on the non-acylating part and a meta- or para-guanidino gp. on the acylating part. Typical fungistats are diguanidines and cpds. have an ester gp. on the non-acylating part and a guanidino gp. on the acylating part. Activity tests are described.

Title: Transistorised ignition system for petrol engine - uses two transistor circuit operated by ignition contact points to drive ignition coil primary
IPC: F02P3/04
Filed: 1979-10-08
Abstract: The electronic components of the system are mounted on a printed circuit board, and the assembly enclosed in a ventilated plastic box. The power transistor heat sink is fixed to the lid of the box. To protect the power transistor from over-voltages induced by the ignition coil, a series pair of Zener diodes is connected from its collector to ground. The base of the npn power transistor is driven by a pnp transistor connected to the ignition contact points. The pnp driver transistor is also protected against collector base overvoltage by a Zener diode. Diodes in the bias circuits of both transistors increase thermal bias stability.

Title: Dust and flame suppression during slag removal from molten iron - after desulphurisation of crude iron using agent contg. calcium carbide, graphite and polyethylene
Inventor: FREISSMUTH SONNENLEITE
IPC: C21C1/02
Filed: 1980-01-07
Abstract: The agent contains CaC2, plus cpds. (I) releasing gases and 2-10% CaF2, so dust and flames are eliminated. The pref. mixt. also contains carbon, and possibly metals possessing a reducing effect, plus metal carbides. The pref. compsn. of the desulphurisation agent, by wt., is 30-90%, esp. 50-85% CaC2; 2-10%, esp. 3-8% CaF2; 2-10% carbon or graphite; and 2-70% cpds. (I), which pref. include 5-40% diamide lime. An esp. pref. compsn. (II) is 85% CaC2, 6% CaF2, 6% graphite, and 3% polyethylene. When slag-free iron in a ladle is treated with a mixt. of CaC2 and diamide lime (a mixt. of CaCO3 and carbon), sulphur is removed from the iron and a slag is formed which is tipped out on the ladle into slag buckets, but this slag creates excessive dust and flames. The invention eliminates this highly undesirable feature.
