Patent DE-3908671-A1 (DE)
Title: Probe for corrosion monitoring
Inventor: PFEFFINGER HARALD DIPL ING
IPC: G01N17/02
Filed: 1989-03-16
Abstract: A probe for corrosion monitoring in the coolant circuit of an internal combustion engine consists of two electrodes which are arranged in the interior of a probe housing, insulated with respect to the coolant. A part of the probe housing consists of a foil of low thickness, which is produced from the same material as the material occurring in the coolant circuit. When the protective effect of corrosion-preventing additives in the coolant diminishes, this foil is destroyed so that coolant reaches the two electrodes. In consequence, a current circuit is made between the electrodes and this fact is reported by a signal output carried out by means of an evaluation unit.

Inventor: EHLERS ACHIM
IPC: A61C13/083
Filed: 1989-10-10
Abstract: In the retentions for applying plastic linings in the dental field the retentions are made of non-metallic material with approx. the same colour as the lining or, alternatively, can be given the same colour through its thickness. The preferred retentions are polymers, glass or ceramic. The base shape/moulding is coated with an adhesive to bond the non-metallic retentions. The retentions concerned will not show through, even where the edges of the plastic liner are thinner. The retentions can also be used in addition to metallic retentions on the main surface. The plastic linings are applied on top of the retentions e.g. by curing under pressure at 100-150 deg.C.. A dental adhesive is best which withstands the temp. concerned. These retentions can be used wherever metal retentions are not available or visually feasible. ADVANTAGE - The retention is not visible through the plastic material even in faulty workmanship such as accidentally grinding the retention or failure to have sufficiently thick lining and especially at the edge. The retentions also ensures that the plastic material is safely bonded to the basic shape at the edges, even if the latter is smooth.

Abstract: The prepn. of 3-arylpyrrole derivs. of formula (I) comprises reacting an N-(arylsulphonylmethyl) foramide of formula Ar1-SO2CH2NHCHO (II) with phosgene or diphosgene in the presence of a base and then directly reacting the reaction mixt. thus obtd. in one step with a cinnamoyl deriv. of formula ArCH+CRA (III); Ar = opt. substd. aryl; R = CN or CO(X)nR1; R1 = H, alkyl, haloalkyl or opt. substd. aralkyl or aryl; X = O or NH; n = 0 or 1; Ar1 = opt. substd. aryl; A = COR1, CONHR1 or SR2; R2 = alkyl, haloalkyl or opt. substd. aralkyl or aryl. USE/ADVANTAGE - (I) are pesticides, e.g. fungicides. The process avoids the use of phosphorus oxychloride previously used. When phosgene is used, the destruction of excess phosphorus oxychloride with water and sepn. of the aq. phase which contains the decomposition prod. is avoided. Excess phosgene is easily removed by blowing N2 through or by satn. with ammonia gas. When diphosgene is used the dosing of equimolar amts. is unproblematic so taht in this case there is also no need for aqueous treatment of the reaction mixt. The use of phosgene or diphosgene rather than phosphorus oxychloride gives considerably higher yields and purer end prod. and can therefore be used on an industrial scale, being favourable both economically and environmentally (no phosphorus contg. effluent).
